Pseudoaneurysm of external iliac artery and compression of external iliac vein after total hip arthroplasty. Case report.

Serious vascular injury as a delayed complication of total hip arthroplasty is unusual. A case of pseudoaneurysm of the external iliac artery and compression of the external iliac vein following loss of acetabular fixation in an uninfected case is reported. There is no previous report of such a complication occurring in the absence of infection, which is considered by some as the main predisposing factor for the event.

Outcome of hepatic artery reconstruction in liver transplantation with an iliac arterial interposition graft.

BACKGROUND: In case of anomal hepatic arterial inflow, it can be necessary to perform revascularization of the liver allograft by iliac arterial interposition graft. METHODS: We analyzed retrospectively 613 liver transplants in a 16-yr period. The hepatic artery (HA) graft group (n = 101) consisted of patients with arterial inflow based on recipient infrarenal aorta using donor iliac artery graft tunneled through the transverse mesocolon. The control group (n = 512) consisted of patients who underwent liver transplantation with routine HA reconstruction. RESULTS: Both groups are homogeneous and comparable. In case of retransplantation, arterial conduit with iliac graft was adopted more frequently instead of conventional arterial anastomosis (24.8% vs. 9%, p < 0.0001). The 1-, 3- and 5-yr overall survival was 85.41, 79.42, 76.57% in the control group and 76.21, 73.43, 73.43% in the HA graft group, respectively (p = ns). The 1-, 3- and 5-yr graft survival was better in the control group (81.51, 73.66, 69.22% vs. 71.17, 62.50, 53.42%) (p = 0.01). In case of retransplantation, the 1-, 3- and 5-yr overall (57.81, 53.95, 41.96% vs. 60, 51.95, 49.85%) and graft survival (57.52, 53.68, 41.75% vs. 56, 50.4, 40.3%) was similar in control and HA graft group, respectively (p = ns). Hepatic artery thrombosis (HAT) rate is 21.8% vs. 8.6% (p < 0.0001) in HA graft group and control group, respectively. The only factor independently predictive of early HAT resulted arterial conduit (p = 0.001, OR = 3.13, 95% CI: 1.57-6.21). Retransplant procedure, donor age and arterial iliac conduit were found to be a significant risk factors for late HAT, at univariate analysis. At multivariate analysis, donor age >50 yr old resulted the only factor independently associated with late HAT (p < 0.0001, OR = 1.05, 95% CI: 1.02-1.07). CONCLUSION: Iliac arterial interpositional graft is an alternative solution for arterial revascularization of liver allograft in case of retransplantation when the use of HA is not possible. In case of primary transplantation, is better not to perform arterial conduit if it is possible, for poor graft survival and high incidence of early HAT, especially in case of liver donor aged over 50 yr.

[Five cases of locally advanced rectal cancer or local recurrence performed intra-arterial infusion chemotherapy via the internal iliac artery].

Intra-arterial infusion chemotherapy via the internal iliac artery was performed in 5 patients with locally advanced rectal cancer or recurrent rectal cancer. Arterial infusion chemotherapy was conducted into the internal iliac artery via bilateral femoral artery following a blood flow change with a coil. 5 FU 500 mg and l-leucovorin 125 mg/m2 were injected weekly. An average time of injections or its duration was 40 (17-74) times or 12.8 (5-23) months, respectively. Disappearance or improvement of symptoms was observed in 4 cases. A decrease of tumor size observed by CT was in 2 cases and a decrease of blood CEA level was in 3 cases. As for the complication of arterial infusion chemotherapy, dermatopathy was found in all of the cases, and sensory disturbance of lower extremities was in 3 cases, infection was in 2 cases and catheter obstruction was in 2 cases. A decrease of dosage or abundance of continuation was done during the course due to complications. Two patients with primary cancer died 1-3 years after the treatment, and 2 patients with recurrence died 7 months to 1 year after the treatment. One patient with primary cancer is continuing the treatment for the last 2 years though multiple metastatic diseases have been confirmed.

Ectopic vascularization of the right kidney by a contralateral origin of the main renal artery from the left common iliac artery: report of a case.

In daily practice, an atypical renal blood supply is a rare finding. An ectopic origin of the right main renal artery from the contralateral common iliac artery was observed when angiography was performed to diagnose irregularities in perfusion of the lower extremities and to determine the necessity for vascular surgical intervention in a 66-year-old man. Conservative treatment was successful in this patient, who suffered from intermittent claudication because of an obstruction of the superficial femoral arteries. The diagnostic approach with angiography is considered to be essential for revealing such anomalies. Conventional vascular surgical reconstruction would have threatened the perfusion of the right kidney in this case.

Internal mammary artery collateral to the external iliac artery: an angiographic consideration prior to coronary bypass surgery.

The role of routine selective angiography of the internal mammary artery prior to myocardial revascularization is controversial. We report a patient with coronary artery disease and peripheral vascular disease in whom the left internal mammary artery supplied blood flow to the left external iliac artery via a collateral network. Thus, selective angiography of the internal mammary artery did play a major role in the proper management of this patient who required coronary bypass surgery. A major potential postoperative complication of left lower extremity ischemia may have been prevented.

Pseudoaneurysm of the deep circumflex iliac artery: a rare complication at an anterior iliac bone graft donor site.

STUDY DESIGN: The formation of a pseudoaneurysm of the deep circumflex iliac artery after the harvesting of an anterior iliac bone graft for spinal fusion is reported. OBJECTIVE: To describe a rare complication at an iliac bone graft donor site. SUMMARY OF BACKGROUND DATA: The iliac bone is a common site for harvesting bone for spinal surgery. Although many complications have been reported, vascular injuries associated with this procedure are rare. To the authors' knowledge, deep circumflex iliac artery injury has not been reported as a complication. METHODS: A 70-year-old man with cervical myelopathy underwent anterior cervical decompression and fusion with an anterior iliac bone graft. Fracture displacement of the anterior superior iliac spine at the donor site was noted 1 week after a second operation, which was performed to reduce the displaced grafted bone. Five months after the second operation, he reported pain and swelling at the donor site. Removal of a hematoma was attempted, which led to massive bleeding that was difficult to control. RESULTS: Angiography demonstrated a pseudoaneurysm of the deep circumflex iliac artery. Selective embolization of the artery was performed, and the bleeding was arrested. CONCLUSIONS: Vascular injury after anterior iliac bone harvesting is rare but can occur. Selective arterial embolization was an effective solution.

Iliac arterial injuries after endovascular repair of abdominal aortic aneurysms: correlation with iliac curvature and diameter.

PURPOSE: To determine the relationship between iliac arterial tortuosity and cross-sectional area and the occurrence of iliac arterial injuries following transfemoral delivery of endovascular prostheses for repair of abdominal aortic aneurysms. MATERIALS AND METHODS: Iliac arterial curvature values and orthogonal cross-sectional areas were determined from helical computed tomographic (CT) data acquired in 42 patients prior to transfemoral delivery of aortic stent-grafts. The curvature and luminal cross-sectional area orthogonal to the median centerline were quantified every millimeter along the median centerline of the iliac arteries. An indicator of global iliac tortuosity, the iliac tortuosity index, was defined as the sum of the curvature values for all points with a curvature of 0.3 cm(-1) or greater, and cross-sectional area (CSA) was indexed for all points as the mean cross-sectional diameter (D = 2 radical[CSA/pi]). Following stent-graft deployment, helical CT data were analyzed for the presence of iliac arterial dissections independently by two reviewers. RESULTS: Eighteen dissections were detected in 16 patients. The iliac tortuosity index was significantly larger in iliac arteries with dissections (35.5 +/- 20.8 [mean +/- SD]) when compared with both nondissected contralateral iliac arteries in the same patients (26.1 +/- 21.0, P =.001) and iliac arteries in patients without any iliac arterial injury (20 +/- 9, P =.009). The tortuosity index was higher ipsilateral to the primary component delivery in 10 of 11 iliac dissections that developed along the primary component delivery route. CONCLUSION: A high degree of iliac arterial tortuosity appears to impart greater risk for the development of iliac arterial injuries in patients undergoing transfemoral delivery of endovascular devices.

Percutaneous transluminal angioplasty of the iliac arteries: 66 experiences.

Sixty-six iliac arteries in 45 patients, 25 male and 20 female, were treated with percutaneous transluminal angioplasty (PTA) for atherosclerotic occlusive disease. Of 103 lesions dilated, 51 were in common iliac and 51 in external iliac arteries. While iliac artery disease was the primary lesion in 18 patients, eight of whom had total occlusion, 27 patients had additional femoropopliteal disease. An overall primary success rate of 84% in dilatation of the stenotic lesions, and 33% in recanalization of totally occluded iliac arteries was achieved. In 12 patients, a prescheduled aortic bifurcation graft was cancelled. In one patient, in addition to recanalization of the occluded common iliac artery, the stenotic distal aorta was also successfully dilated. Angioplasty was unsuccessful in 12 patients. There were only three severe complications requiring surgical assistance. To date, less than 2 years, there has been a patency rate of 100%. Transluminal angioplasty is the treatment of choice for single stenotic lesions of the iliac arteries. Lack of calcification is not an absolute guarantee of success, but a favorable factor.

Extra-anatomic arterial reconstruction with ligation of common iliac arteries and embolization of the aneurysm for the treatment of abdominal aortic aneurysms in high-risk patients.

PURPOSE: The mortality of an unrepaired abdominal aortic aneurysm (AAA) generally exceeds the mortality associated with surgical repair. However, as our longevity increases, more frequently we see patients whose risk of surgical repair approximates the risk of rupture. We present an extra-anatomic bypass graft with complete aneurysm exclusion by iliac ligation and coil embolization of the aneurysm as an alternative for these high-risk patients. METHODS: An extra-anatomic bypass graft, followed by bilateral iliac artery ligation (retroperitoneal approach) and complete coil embolization of the AAA, was performed in eight patients (mean age, 77 years) found to be at prohibitive operative risk because of multiple comorbidities (American Society of Anesthesiologists class IV). Most patients (5 of 8) were symptomatic on presentation with a mean AAA diameter of 7 cm (range, 6.7-9.5 cm). We repair approximately 30 infrarenal aneurysms per year electively at our institution. RESULTS: All patients tolerated the surgical procedures. The average hospital stay was 8 days. All but two aneurysms demonstrated complete thrombosis by 48 hours. After 48 months there was no incidence of graft thrombosis, peripheral ischemia, visceral ischemia or thrombus infection. There was one perioperative death from aspiration pneumonia. Seventy-five percent (6 of 8) of patients have survived at least 1 year without surgical complications. No patient has had a ruptured aneurysm. CONCLUSION: Combining an extra-anatomic bypass graft and complete exclusion of the AAA by ligation of the common iliac arteries and a coil embolization is an effective, less invasive treatment option for patients with AAA and prohibitive operative risk. We emphasize the need for complete embolization documented by decreased aneurysm size.

Management of isolated common iliac artery aneurysms.

PURPOSE: Since isolated common iliac artery aneurysms are rare and there is no consensus regarding some aspects of their management, we reviewed our recorded experience with common iliac artery aneurysms from 1977 through 1993. METHODS: We were able to identify 25 patients having a total of 33 common iliac artery aneurysms on the basis of information maintained by our medical records staff, old surgical logs and a departmental registry that was implemented in 1989. Follow-up data were collected from outpatient charts and by telephone contact. New imaging studies were obtained for 14 patients who either underwent common iliac artery aneurysm repair without aortic replacement (aortic ultrasound scans, n = 7) or had no surgical treatment whatsoever (computerized tomography of the abdomen and pelvis, n = 7). RESULTS: All 25 patients were men (mean age, 71 years). Eighteen patients (72%) had elective (n = 14) or urgent (n = 4) operations to repair common iliac artery aneurysms with mean diameters of 3.8 cm and 5.8 cm, respectively. There was one postoperative death (5.5%) in conjunction with complementary renal revascularization in a patient with pre-operative renal insufficiency. During a mean follow-up period of 50 months, two (29%) of the seven patients who had not received bifurcation grafts at the time of their common iliac artery aneurysm procedures had developed infrarenal aortic aneurysms. Seven (28%) of the original 25 patients were observed without intervention for common iliac artery aneurysms measuring 2-2.5 cm in diameter. No common iliac artery aneurysm enlargement or new aortic aneurysms have been documented in any of these patients at a mean follow-up interval of 57 months. CONCLUSIONS: In our limited experience, the risk for spontaneous rupture appears to be concentrated among common iliac artery aneurysms exceeding 5 cm in diameter, while those that are less than 3 cm in diameter may fail even to enlarge under observation. Therefore, common iliac artery aneurysms measuring > or = 3 cm in size probably warrant surgical treatment, at which time simultaneous aortic replacement also should be a serious consideration.

Percutaneous transluminal angioplasty and stenting for iliac artery occlusive disease.

Atherosclerotic iliac artery stenoses respond well to simple balloon angioplasty and have the best results of all of the peripheral vessels. Nonetheless, initial technical failures occur in as many as 20% of patients, most of which can be salvaged with intravascular stenting, as can many of the potential complications; however, even though the initial technical success rates for stenting approach 100%, stenotic recurrences within stents are not infrequent. Whether promising new concepts, such as brachytherapy, gene therapy, and endoluminal grafting, will have a durable impact on the results of iliac angioplasty is yet to be seen. Meanwhile, the excellent results of endoluminal treatment of patients with iliac artery occlusive disease, combined with the relatively low risk for complications compared with surgical revascularization, ensure an enduring role for this modality of treatment and a diminution in the fraction of patients requiring surgery to correct their iliac artery occlusive disease.

Intravascular sonographic evaluation of iliac artery angioplasty: what is the mechanism of angioplasty and can intravascular sonography predict clinical outcome?

OBJECTIVE: The purpose of this study was to establish the arterial responses of the iliac artery after percutaneous transluminal angioplasty (PTA), using intravascular sonography, and to correlate intravascular sonography parameters with clinical outcome. SUBJECTS AND METHODS: The study included 21 patients studied with intravascular sonography before and after PTA of the iliac artery. Distinction was made between intravascular sonography cross sections collected from the common iliac and those from the external iliac artery. First, qualitative and quantitative intravascular sonography data obtained at the most stenotic site were compared with data derived from all corresponding cross sections of the dilated segment. Second, the predictive value of intravascular sonography parameters for the patient outcome was assessed. RESULTS: The free lumen and media-bounded areas seen in the common iliac artery were larger than those seen in the external iliac artery. Qualitative and quantitative effects of PTA observed with intravascular sonography on the two types of artery were not different. Vascular damage occurred in 81% of the patients. The frequency of vascular damage at the most stenotic site was slightly lower than in each dilated segment studied. The reduction in area stenosis after intervention was associated with an increase in the free lumen and media-bounded areas, whereas the plaque area reduced only slightly. The increase in the free lumen and media-bounded areas and the decrease in the plaque area at the most stenotic site after intervention were larger than the mean values. Qualitative data seen with intravascular sonography at the most stenotic site before and after intervention were not predictive of the patient outcome. In patients with an uneventful outcome after intervention, the free lumen area measured at the most stenotic site after PTA was larger and the area stenosis was smaller than in patients with a failure. CONCLUSION: This study of intravascular sonography established that although the common iliac artery is larger than the external iliac artery, the qualitative and quantitative effects of PTA in both types of artery were similar. The size of the free lumen area and the degree of stenosis seen with intravascular sonography after PTA at the most stenotic site may be predictive of a patient outcome.

Selection of patients with lower limb arterial occlusive disease for endovascular treatment of the iliac arteries with duplex scanning.

The aim of this study was to evaluate the role of duplex scanning in selection of patients with lower limb arterial occlusive disease for endovascular treatment of the iliac arteries. From January 1995 through May 2000, 183 patients having chronic lower limb arterial insufficiency who underwent duplex scanning of the lower extremity arteries with available aortoiliac scans within 3 months before conventional aortoiliac diagnostic angiography and/or endovascular intervention of the iliac arteries were studied retrospectively. The findings obtained from duplex scanning and angiography were analyzed in a blinded manner by 2 investigators. Limbs having category 1, 2, and 3 lesions according to duplex scan findings were interpreted as being suitable for endovascular intervention. The comparison between duplex scan findings and angiography was analyzed by the third investigator. During 93 percutaneous transluminal angioplasty (PTA) procedures, 133 arterial segments, common or external iliac, were dilated with stent placement in 70. Bilateral interventions were performed in 25 cases, and of 68 unilateral interventions, 57 were at only 1 arterial segment. The accuracy, sensitivity, specificity, and negative and positive predictive values of duplex scanning to appropriately categorize the iliac artery lesions into suitable or unsuitable for endovascular intervention were 90%, 95%, 83%, 90%, and 92%, respectively when the inconclusive duplex scans were excluded (11%). In 6 patients with lesions suitable for PTA according to duplex scanning and angiography, PTA was not performed owing to clinical reasons. The accuracy of duplex scanning in predicting the performance of endovascular intervention was 88%. It is concluded that iliac artery endovascular procedures in limbs with chronic occlusive disease can be reliably planned according to duplex scan findings.

Gluteal necrosis after acute ischemia of the internal iliac arteries.

Ligation of the internal iliac artery mostly remains without consequences because of the well established collateral network. In patients with compromised collateral circulation however, acute interruption of both hypogastric arteries during aorto-iliac surgery or transluminal embolisation can lead to necrosis of the gluteal muscles and other adjacent organs (rectum, bladder, lumbosacral plexus). Experience with 3 similar cases after aorto-iliac surgery demonstrates two main intraoperative mechanisms: 1. Embolisation, 2. Ligature of both internal iliac arteries in patients with compromised arteriosclerotic collaterals. Despite of adequate therapy, mortality is over 70%. The most important feature during aorto-iliac operations is to preserve at least one internal iliac artery by either reimplantation of the main stem or by an additional bypass to this artery.
