[The popliteal artery entrapment syndrome. Clinical experience].

The authors report their experience in treating three cases of popliteal artery entrapment. The analysis is based on the onset and the gap of time between the symptoms and the diagnostic certainty referred to the age of the patients. The diagnostic approach and follow-up is discussed including magnetic resonance of popliteal fossa. The surgical approach was constantly a shaped dorsal incision, and the reconstruction was performed in two cases with carbon coated dacron grafts of 6 mm diameter for the inadequacy of veins available. Any true aneurysm formation was identified. All grafts are patent on follow-up and the viability of the popliteal artery that underwent to simply myotomy is confirmed too by doppler ultrasound. Any recurrence of symptoms is recognized, in only one case was observed a concomitant entrapment in the other leg, not treated now is underlined. The advantage available for the patient in a physiokinetic therapy program, forerunner of a complete functional restoring, especially in athletic patients.

[Reconstructive surgery in occlusive lesions of the femoral and popliteal arteries].

The analysis of 306 reconstructive operations performed in 297 patients with occlusion lesions of the femoral and popliteal arteries was made. Remote results were observed as long as 11 years. The collateral shunting by synthetic prostheses was performed in 43 patients, endarterectomy--in 127 cases, autovenous transplantation--in 79 cases, and plasty of the profound artery of the femur--in 58 cases. The data obtained enabled the efficacy of different reconstructive operations on femoral and popliteal arteries to be assessed. The indications and contraindications for their fulfillment are determined. The causes of postoperative rethromboses are discussed.

Popliteal artery entrapment syndrome. A report of 2 cases.

Popliteal artery entrapment results from compression of the artery between the medial femoral condyle and the muscles of the popliteal fossa, either through an abnormal muscle origin or through an abnormal course of the artery. The consequence of this entrapment is intermittent claudication, often presenting at a young age. Two cases are presented with a brief review of the condition.

[A case of adventitial cystic disease of the popliteal artery preoperatively diagnosed by magnetic resonance imaging].

A rare case of adventitial cystic disease of the popliteal artery in 34-year-old male was encountered. The patient visited our hospital with a complaint of intermittent claudication and numbness in the left leg when bending. Angiography indicated a crescent stenosis in the popliteal artery. Magnetic resonance imaging (MRI) showed the mass having high density at T2 imaging as which might be compatible to adventitial cystic disease of the artery. Cystectomy was performed and resulted in improvement of symptoms.

[Magnetic resonance tomography and magnetic resonance angiography in diagnosis of complicated popliteal artery aneurysm].

Regarding the frequency of aneurysms, the popliteal artery comes third behind the abdominal aorta and the iliac arteries. In up to 50% of cases a sudden limb-threatening thrombotic occlusion may occur. Early surgical intervention is the therapy of choice. We report the case of a 56-year-old patient whose popliteal aneurysms (PAs) in both legs had been bypassed with a venous graft some years previously. He presented with acute pain and tumescence in the left popliteal fossa combined with inflammatory symptoms. Neither ultrasonography nor DSA could distinguish between an extravascular inflammatory process, an anastomotic aneurysm and a partial reperfusion of the original PA due to a leaking anastomosis. The correct diagnosis was provided by MRI in combination with MRA, confirmed by the intraoperative findings. The value of MRA in the diagnostic imaging of the vasculature of the lower extremities is discussed and compared alternative methods.

Surgical treatment for popliteal artery entrapment syndrome.

PURPOSE: This study was a retrospective review of 11 limbs of 10 patients with popliteal artery entrapment syndrome (PAES) treated surgically in a 20-yr period. METHODS: The patients were aged 34.7 +/- 17.4 SEM yr. Arteriographic findings varied, showing medial deviation in two limbs, poststenotic dilatation in four limbs and occlusion of the popliteal artery in five limbs. In addition, computed tomographic (CT) scanning showed positive findings of PAES in all the limbs. RESULTS: The surgical procedures consisted of musculotendonous section (MTS) with autogenous saphenous vein (ASV) graft in seven limbs, MTS and ASV patch angioplasty with or without thromboendarterectomy in three limbs, and MTS alone in one limb. All the ASV grafts were found to be patent during the postoperative follow-up period (10.9 +/- 4.0 yr). CONCLUSION: CT scanning was demonstrated to be the most sensitive diagnostic modality for PAES, and MTS with or without ASV grafting method was considered to be the best surgical procedure for PAES.

Delayed presentation of traumatic popliteal artery pseudoaneurysms: a review of seven cases.

OBJECTIVES: to examine the management and outcome of patients with traumatic popliteal artery pseudoaneurysms with delayed presentation. MATERIALS: over a 2-year period 7 patients with traumatic popliteal pseudoaneurysms presenting to a tertiary referral unit after a delay of 1 month were reviewed. METHODS: a retrospective review of clinical records. RESULTS: the median interval between injury and presentation was 1.5 months (range 1-24 months). Penetrating trauma from gunshot wounds was the cause of the initial vascular injury in 6 patients and a stab wound in one. All patients had large pseudoaneurysms of more than 8 cm filling the popliteal fossa with variable degrees of fixed flexion deformity (FFD) of the knee. Severe FFD of more than 40 degrees was noted in 2 patients and 3 others had mild flexion deformities of 10 to 20 degrees. Six patients underwent repair of the pseudoaneurysm. One patient required an above knee amputation due to an infected false aneurysm. There were no deaths or graft related complications. Despite aggressive post-operative physiotherapy only 2 patients were able to completely straighten the leg at the time of discharge. CONCLUSIONS: in patients with neglected popliteal artery pseudoaneurysms, morbidity is associated with the pre-operative degree of fixed flexion deformity of the knee.

20-year experience with operations for popliteal artery aneurysm.

At the 2nd Department of Surgery, St. Anne's University hospital Brno, a total of 76 operations for popliteal artery aneurysm were performed in 67 patients in the last 20 years, in period 1985-2004. 63 operations were elective and 13 urgent. For reconstruction, autologous saphenous vein was used in 53 cases, vascular prosthesis in 15 cases, and a cryopreserved vein allograft in 3 cases. In 5 cases, amputation for advanced lower limb ischaemia was performed without arterial reconstruction. Elective operation is indicated in all patients with popliteal artery aneurysm, and it is associated with a relatively low risk for the patient. In fact, it is a preventive operation. In the acute stage, there is a higher risk of complications and (potential) amputation (Fig. 1, Ref. 8).

Femoral avulsion fracture of the posterior cruciate ligament in association with a rupture of the popliteal artery in a 9-year-old boy: a case report.

Ruptures of the posterior cruciate ligament (PCL) and especially proximal bony avulsion fractures in children are very rare. This in combination with a rupture of the popliteal artery is extremely rare. Thus, an exact incidence is not available from the literature. Overall, these injuries are severe and often lead to chronic knee instability. We report a case of a 9-year-old boy who suffered a traumatic displacement of the left knee with a rupture of the popliteal artery. Prior to transfer to our department, he was treated by a saphenous vein bypass graft and by a transfixation of the knee using two oblique percutaneous pins. We performed magnetic resonance imaging (MRI) scan of the knee which revealed a femoral avulsion fracture of the PCL. Other ligaments and menisci were intact. A transosseous femoral fixation using non-absorbable stitches was carried out. A 1-year follow-up after surgery demonstrates intact peripheral perfusion and sensation, straight axes of both legs and a physiological gait. Minimal differences of the length and circumference of both legs could be measured. The posterior laxity (Lachman-test) was about 5/8 mm (right/left knee) and 2/5 mm (right/left knee) in 90 degrees flexion. The range of motion (extension/flexion) was 5/0/140 degrees -/5/100 degrees (right-left knee). Intact cruciate ligaments were confirmed by MRI. Minimal experience exists in treatment of combined injuries to the PCL and the popliteal artery in children.

Entrapment of popliteal artery and vein.

Entrapment of the popliteal vessels is reported to be rare. Lack of knowledge of this entity may result in a low reported incidence. To help wider appreciation and early recognition of this condition, we report five cases of popliteal vessel entrapment and discuss the associated features.

Popliteal artery injury associated with knee dislocation: improved outlook?

Popliteal artery injury due to knee dislocation is an injury complex that is being reported with increasing frequency. A review of the literature from 1974 to 1978 reveals 40 new cases. Of these cases, 85 per cent underwent successful arterial repair, an encouraging figure. although few, large individual series exist, it is felt that an improved prognosis may be expected. Four case reports from the last year at the author's institution are presented. Various aspects of diagnosis and treatment are analyzed and recommended.

Adventitial cyst of the popliteal artery. Report of a case.

A case of cystic degeneration of the popliteal artery in a 58-year-old male is reported. Symptoms consisted of a claudication of abrupt onset and the correct diagnostic clue was initially given by magnetic resonance of the knee and confirmed by angiography. Treatment consisted of surgical removal of the cyst and saphenous vein angioplasty of the popliteal artery, with good anatomic and functional result at one year follow-up. Diagnostic tools and treatment of the condition are briefly discussed.

The continuing challenge of aneurysms of the popliteal artery.

This report is an analysis of 252 popliteal artery aneurysms (PAA) in 167 patients treated surgically at the University Hospital in Zurich during a 27 year period from 1965 to 1991. The predominance of male patients (95 percent) was consistent with that of other reports. PAA were bilateral in 51 percent of the patients and were associated with aneurysms at other sites in 38 percent. Atherosclerosis was by far the most common cause (98 percent). PAA were symptomatic in 75 percent of the patients, the predominant findings being ischemia from emboli, thrombosis or rupture. Primary amputation was required in 23 extremities. Surgical reconstruction with bypass was performed for 229 PAA. A secondary amputation was necessary in 18 limbs. The risk of complications from popliteal aneurysms, and the good results from surgical treatment suggest that a revascularization procedure in the asymptomatic stage should be recommended unless specific contraindications exist. We conclude that surgical treatment should be performed in symptomatic and asymptomatic PAA larger than 2 centimeters in diameter. Long term results of surgical reconstruction are improved if an autogenous saphenous vein is used and if reconstruction is performed before the occurrence of complications. Polytetrafluoroethylene prostheses should be used when an autologous saphenous vein is not available. The use of Dacron (polyester fiber) grafts is no longer indicated.

Distal profunda femoris to popliteal artery bypass for patients with a short length of long saphenous vein.

A technique of distal profunda femoris to popliteal artery bypass is described in two patients in whom the length of long saphenous vein available for grafting was too short for a conventional femoropopliteal bypass. Because each patient has a large profunda system which was free from proximal disease, a bypass was constructed betweeen the distal profunda femoris and the upper popliteal arteries, utilizing the short length of long saphenous vein available. Both patients had complete relief of their symptoms and objective evidence of improvement.

Post stenotic aneurysm in popliteal artery entrapment syndrome.

In a retrospective review of 74 cases of Popliteal Entrapment Syndrome collected over a 16 year period, 10 cases of aneurysm were found (13.5%). This represents an incidence of 26% of the 38 cases of popliteal aneurysm of any etiology seen during the same period of time. In contrast to atherosclerotic aneurysms, these aneurysms were seen in a young age group (21-30 years of age) and all were associated with popliteal entrapment. Evidence is presented to support our opinion that these aneurysms are post-stenotic in origin. We feel that young adults with symptoms of leg ischaemia and evidence of an aneurysm of the popliteal artery should be investigated for popliteal entrapment and treated before complications occur. We have found a posterior approach to be the most satisfactory method of exploring the popliteal fossa.
