External iliac artery and lumbosacral plexus injury secondary to an open book fracture of the pelvis: report of a case.

Lumbosacral plexus or external iliac artery injuries associated with pelvic fracture are reported rarely in the literature. A case involving a noncompound open book pelvic injury with diastasis of the symphysis pubis and combined ipsilateral lumbosacral plexus and external iliac artery injury is reported. Repeated clinical examination to diagnose vascular lesions with evolving pulse deficits is emphasized.

The early development of the lymphatic system in mouse embryos.

The early development of the lymphatic system was studied in embryos of an inbred strain of the laboratory mouse. During the first stage of its development the system is represented by a more or less regular series of small and blind-ending outgrowths of the major embryonic veins which develop in a cranio-caudalward direction from the jugular to the pelvic region. As a result of differences in growth rates of adjacent anatomical structures this series of early lymphatic primordia becomes subdivided into 4 singular primordia and 12 groups of primordia. After the constituents of each group of early primordia have fused, 16 isolated lymphatic plexuses (sacs) are formed of which 14 are in bilaterally symmetric and 2 are in a median line position: i.e. bilaterally: (1) the jugulo-axillary lymph sac situated lateral to the anterior cardinal vein and dorsal to the primitive ulnar vein and its major branch, the external mammary vein, (2) the paratracheal lymph plexus situated medial to the anterior cardinal vein, (3) the internal thoracic lymph plexus situated lateral to the thoracic part of the posterior cardinal vein, (4) the thoracic ducts situated medial to the thoracic part of the posterior cardinal vein, (5) the lumbar lymph plexus situated dorso-lateral to the abdominal part of the posterior cardinal vein, (6) the subcardinal lymph plexus and (7) the iliac lymph plexus situated ventro-lateral to the abdominal part of the posterior cardinal vein; and in the median line: (8) the subtracheal lymph plexus situated at the confluence of the pulmonary veins and (9) the mesenteric lymph plexus situated near the confluence of the splenic and the superior mesenteric veins. Except for some openings at the jugulo-subclavian confluence all connections with the veins disappear. From the primordia extensions grow out centrifugally. They invade the surrounding tissues and, in part, fuse with similar sprouts of adjacent primordia. In this way a continuous system of lymph truncs is formed that opens into the venous system at the jugulo-subclavian confluence.

Ischemic injury to the spinal cord or lumbosacral plexus after aorto-iliac reconstruction.

Between January 1, 1980, and June 30, 1989, 9 patients (6 males and 3 females) developed ischemic injury to the spinal cord or lumbosacral plexus following 3,320 operations on the abdominal aorta (0.3%). The incidence of this complication was 0.1% (2 of 1,901) after elective and 1.4% (3 of 210) after emergency abdominal aortic aneurysm repair, and 0.3% (4 of 1,209) after repair for occlusive disease. Three of the latter had prior clinical evidence of distal embolization. Eight grafts were bifurcated (aorto-iliac:four, aorto-femoral: three, aorto-ilio-femoral:one). One patient underwent extra-anatomic revascularization. Only two patients had supraceliac aortic cross-clamping and one patient underwent exclusion of both internal iliac arteries. Four patients had hypotension. Early mortality was 22% (two of nine). Severe perioperative complications, mostly due to associated visceral and somatic ischemia and sepsis, were present in seven of the nine patients. The extent and type of the neurologic injury correlated with long-term outcome. Patients with ischemic injury of the lumbosacral roots or plexus had better recovery. Attention to the pelvic circulation and the collateral blood supply is important. Use of gentle technique to prevent embolization, avoidance of hypotension and prolonged supraceliac cross-clamping, revascularization of at least one internal iliac artery, and the use of heparin may decrease but not eliminate paraplegia. Once this unexpected complication occurs, careful neurologic evaluation should be done to localize the lesion and aid prognosis.

Influence of ligation of the internal iliac veins on the venous plexuses around the sacrum.

Excessive bleeding is a significant problem during total sacrectomy. Ligation of the internal iliac veins to control bleeding from the pelvic venous plexus has been reported to be mandatory. However, despite ligation of the internal iliac veins, excessive hemorrhage from the pelvic and epidural venous plexuses is often encountered. We postulated that ligation of the internal iliac veins increases blood loss during total sacrectomy and we investigated the influence of ligation of the internal iliac veins on the pelvic and epidural venous plexuses in white rabbits. We also investigated the influence of the animal's operative position on the epidural venous pressure. Venography was performed to study the differences in blood flow patterns before and after ligation of the internal iliac veins. Without ligation, contrast medium passed into the inferior vena cava, but not into the epidural venous plexus. The epidural venous plexus was contrast-filled when the internal iliac veins were ligated. The pressure in the internal iliac veins was increased with their ligation, and decreased with ligation of the abdominal aorta. The pressure was also decreased with intentional bleeding from the epidural venous plexus, and with changing the animal's position to headdown. Ligation of the internal iliac veins leads to congestion of the pelvic venous and epidural venous plexuses. Ligation of the internal iliac arteries and positioning the animal headdown were effective ways to resolve the congestion in these venous plexuses.

Sexual function following aortoiliac reconstruction.

Impotence due to atherosclerotic disease of the aorta and iliac arteries presents as failure to achieve erection. Sterility after aortoiliac reconstructive surgery is more common and presents as inability to ejaculate. If the superior hypogastric sympathetic plexus (presacral nerve) is preserved, sexual function can be maintained in 90% of cases.

Sexual function after aorto-iliac vascular reconstruction. Which is more important, the internal iliac artery or hypogastric nerve?

Sixty patients undergoing surgical reconstruction by classical or modified methods for aorto-iliac vascular disease were studied as to postoperative sexual function. Preoperative impotence was present in approximately half of the patients with abdominal aortic occlusion. Although internal iliac arterial blood flow was regarded as an important factor in sexual function, only a slight correlation was noted between circulatory insufficiency and postoperative sexual dysfunction. Preservation of both trunks or the left trunk of the hypogastric nerve led to a marked decrease in the incidence of ejaculation disturbances. We concluded preservation of the hypogastric nerve was more beneficial than maintenance of internal iliac arterial blood flow.

Preservation of ejaculation in stage I non-seminomatous testicular tumours.

The loss of ejaculation is the most serious postoperative complication of patients having stage I non-seminomatous testicular tumours. In order to preserve the capability for ejaculation even after retroperitoneal lymphadenectomy (RPA) the preservation of paravertebral sympathetic ganglia but that of the sympathetic nerves in the territory of aortic bifurcation and common iliac arteries to be ulcessary.

The influence of the sampling point on testicular steroid concentrations in spermatic venous blood: a physiological approach to evaluate testicular secretion.

In the present study, we have evaluated the influence of the location of the blood sampling in the spermatic vein on the steroid concentrations observed. Simultaneous blood sampling at two different points of the spermatic vein (iliac level and pampiniform plexus) was perfomed in the same patients during a surgical protocol for varicocelectomy. In order to further evaluate which of the two sampling points is more useful to investigate testicular secretion, we have performed both forms of sampling in 4 volunteers given an HCG stimulation 24 h before the surgical procedure. It was found that levels of testosterone (T) and 17 alpha-hydroxyprogesterone (17-OHP) were higher in the pampiniform plexus (scrotal) than at the iliac sampling point (T scrotal 1,168.343 +/- 142.65 nmol/l, iliac 850.63 +/- 143.411 nmol/l, n = 21, p less than 0.01; 17-OHP scrotal 260.130 +/- 43.14 nmol/l, iliac 164.46 +/- 31.02 nmol/l, n = 17, p less than 0.01). This indicates that spermatic blood collected at the scrotal sampling point has received more blood coming from the testis than the blood collected at the iliac point. We did not observe significant differences in progesterone and delta 4-androstenedione (delta 4) levels between the two samplings. The T/delta 4 ratio was significantly lower in the iliac than in the scrotal sampling (T/delta 4 scrotal 31.420 +/- 6.69; iliac 15.41 +/- 3.84; p less than 0.05). After HCG stimulation, testosterone concentrations were higher in the pampiniform plexus than in the iliac sample. This suggests that the first sampling point is more proper for studying testicular secretion.(ABSTRACT TRUNCATED AT 250 WORDS)

Arterial supply to the hypogastric and presacral nerves.

The hypogastric nerves take an arterial supply from the internal iliac artery either directly or from one of its main branches close to its origin from the parent trunk. Sometimes the supply is from the lower end of the common iliac artery. In half the cases examined the presacral nerve takes an arterial supply from the aorta at its bifurcation.

Total laparoscopic iliac artery aneurysm repair using endoscopic techniques and endovascular balloon occlusion.

UNLABELLED: We present a novel total laparoscopic technique to treat patients with iliac and aorto iliac aneurysms. The laparoscopic procedure does not require clamping of the iliac arteries because of a hybrid approach. REPORT: Laparoscopic exposure of the aorta is performed using transperitoneal left retrorenal access. A transfemorally placed balloon catheter blocks the external iliac artery. Two haemostatic sheaths are inserted directly through the skin into the abdominal cavity. Balloons are passed through these sheaths to block the common iliac artery and the hypogastric artery, allowing bypass grafting to be performed with appropriate haemostatic control. DISCUSSION: The technique described preserves inflow into the hypogastric arteries . This is accomplished by a combination of laparoscopic and endovascular techniques reducing the problems that can be caused by clamping diseased arteries.

Impotence after aorto-iliac surgery: current concepts.

The retrospective study of 38 male patients undergoing aorto-iliac reconstructive and abdominal aortic aneurysm surgery was carried out. The study demonstrates the deficiency in the pre-operative, intra-operative, and post-operative evaluation of these patients regarding the factors affecting impotence. Recommendations are made, and a flow sheet is compiled to assist the vascular surgeon in the evaluation and management of these patients.
