[Endarterectomy of the femoral and popliteal arteries].

The experience of 127 operations for endarterectomy of occlusions of the femoral and popliteal arteries in 122 patients is analyzed. The remote results were observed for 10 years. The cumulative analysis within 10 years after operations have shown 27% of endarectomized arteries to remain passable. The best results were obtained when using the gaseous method modified by the authors, for correction of short occlusions in combination with good outflow pathways. With this form of pathology 68% of arteries are found to be passable within 10 postoperative years.

Cystic adventitial degeneration as a cause of dynamic stenosis of the popliteal artery: a case report.

Cystic adventitial degeneration, which is generally localized in the popliteal artery, leads to a dynamic, exercise-dependent flow inhibition. The cysts of the adventitia, which increase in size with exercise, cause an increasing degree of stenosis which can be completely reversed after a longer period if rest. Angiographic presentation may therefore be misleading. Functional examination with Doppler sonography is able to identify the obstruction in such cases. Resection of the involved vessel and restoration of flow by interposition of a vein graft is the therapy of first choice.

Adventitial cystic disease of the popliteal artery: early recurrence after CT guided percutaneous aspiration.

Adventitial cystic disease of the popliteal artery is a rare condition of debated aetiology. The recommended treatment has been cyst removal with or without replacement of the artery. Recently percutaneous aspiration has been suggested as another method of treatment for this condition. In this case, percutaneous aspiration was performed twice. Surgical intervention was eventually performed because of early cyst recurrence. Our experience suggests that aspiration is a treatment option but, if used, close long-term follow-up is necessary to detect recurrence.

[Entrapment and cystic degeneration of the adventitia as a cause of occlusion of the popliteal artery].

The entrapment syndrome and the cystic adventitial degeneration of the popliteal artery are diseases affecting relative young patients. Four cases of entrapment and one case of cystic degeneration are demonstrated. In one patient also an entrapment of the popliteal vein is demonstrated. In all patients the outcome of vascular reconstruction was good. For the entrapment syndrome the posterior approach is prefered.

Risk factors for arthroscopic popliteal artery laceration.

A case report is presented in which a patient with well-documented pigmented villonodular synovitis sustained a disruption of the popliteal artery without evidence of penetration of the posterior capsule. The patient had had several extensive open synovectomies in the prior 20 years. These included popliteal space exposure and dissection. At the time of open arterial repair, multiple nodules of pigmented scar were noted densely binding the popliteal artery to the surrounding muscle and fascial tissues. The arthroscopist should be aware that distension and instrumentation of the knee joint in such patients should be performed with extreme care to avoid arterial disruption.

Ultrasound diagnosis of popliteal arterial aneurysms.

"B" mode ultrasound scanning is useful in the diagnosis of popliteal arterial aneurysms. It offers advantages over physical examination and arteriography, since these aneurysms are sometimes difficult to palpate and may be partially filled with laminated clot. The technique is noninvasive and without known hazard in this location. "B" mode ultrasound scanning promises to be useful in the diagnosis of aneurysms of other extremity arteries. It has already been useful in confirming the presence of femoral false aneurysms. Greater familiarity with the technique and improvepd technology will result in even greater reliance on ultrasound diagnosis.

True aneurysm of popliteal artery due to trauma: a case report.

Incidence of true aneurysm of popliteal artery due to trauma is extremely rare and not yet known. Medlar search failed to reveal any report. This case is presented due to its rarity and atypical clinical manifestations. An awareness of this can help in preventing unnecessary amputations.

Popliteal artery injuries: civilian experience with sixty-three patients during a twenty-four year period (1960 through 1984).

Our experience with 63 patients who had popliteal artery injuries sustained in civilian accidents is reported. Blunt injuries occurred in 53 patients and 49 had associated skeletal injuries. Eighteen patients suffered knee dislocation; six of these patients had associated fractures. Fractures of the upper third of the tibia occurred in 21 patients. Five patients had irreversible ischemia and required primary amputation. Thirteen amputations were required in 58 patients in whom arterial repair was performed, for an amputation rate of 22%. There were no amputations in 19 patients treated less than 6 hours after injury was sustained. Four deaths occurred. Fasciotomy was performed in 20 patients. Skeletal injuries were usually treated with external fixation.

The surgical treatment of blunt and penetrating injuries of the popliteal artery.

Thirty-six patients sustaining blunt and penetrating injuries to the popliteal artery underwent vascular reconstruction with an average ischemic interval of eight and one-half hours (range: four to 14 hours). There were 16 associated venous injuries, 15 nerve injuries, and 20 fractures with or without knee dislocations. Arterial repair was performed by saphenous vein interposition graft in 23 patients and by end-to-end anastomosis in 16 patients (three patients had more than one operation). Eight of the venous injuries were reconstructed and the remaining eight veins were ligated. Fasciotomy was performed in 22 patients. Skeletal stabilization by external support was necessary in 12 instances and by internal fixation in eight patients. Five patients required amputation after vascular reconstruction failed. The presence of an ischemic interval greater than ten hours, associated fractures, and/or knee dislocation carried a serious prognosis for limb survival.

Popliteal artery entrapment syndrome: collaborative experience of the Joint Vascular Research Group.

BACKGROUND: Popliteal artery entrapment syndrome (PAES) is rare and probably underdiagnosed. This study reviewed a collected experience. METHODS: Patients were identified by the Joint Vascular Research Group (vascular surgeons from ten hospitals serving a population of approximately four million) during 1984-1995. Case notes were reviewed. RESULTS: Twenty-one legs in 17 patients were identified with PAES. There were 15 men and two women. The median age at presentation was 29 (range 14-45) years. One patient was excluded because no further information was available. PAES was bilateral in four patients in whom three legs were asymptomatic. At presentation, the duration of symptoms ranged from a few hours (acute leg ischaemia) to intermittent claudication of 6 years' duration. Primary investigation included angiography (20 patients), duplex imaging (four), plain radiography (one) and magnetic resonance imaging (one). In two cases, attempted thrombolysis failed. Surgery was carried out on 17 legs but failed in two. No amputations were required. Following surgery, 12 legs were asymptomatic and five had residual symptoms. CONCLUSION: PAES should be excluded in young patients with intermittent claudication or acute ischaemia.

Intermittent claudication in an athlete--popliteal artery entrapment: a case report.

This case study reports a 26 year old female athlete who presented with a history of cramp-like right calf pain. She was limited to a walking distance of only three blocks. She had been referred to the Sports Medicine Clinic with a diagnosis of "shin splints". On examination of the pedal pulses it was found that the right posterior tibial pulse was absent. A diagnosis of popliteal artery entrapment was made which was confirmed by Doppler studies following treadmill walking and femoral arteriograms. Surgery was performed which included resection of the entrapped artery by the plantaris tendon and endarterectomy, plus patch graft angioplasty. The artery had been completely occluded. The patient resumed full activity pain free. This case report emphasizes that all leg pains in athletes are not variants of "shin splints". Popliteal artery entrapment is an uncommon condition that requires early detection. A detailed history and thorough examination of the peripheral pulses is essential to prevent long term sequelae of arterial deficiency.

Femur ostochondroma and secondary pseudoaneurysm of the popliteal artery.

Osteochondroma is the most common skeletal benign tumour. It may present in a solitary form or as part of an autosomal dominant hereditary syndrome affecting several bones simultaneously. It is found most often in the knee region. It is generally asymptomatic although it may cause complications, including vascular disorders. In view of anatomical circumstances, the popliteal artery is most frequently involved in this type of complication. This is a case report of a 9-year-old boy who referred with pain in the distal third of his femur. Osteochondroma was initially diagnosed through plain X-ray. In view of worsening symptoms, an ultrasound and magnetic resonance imaging were performed and the patient was diagnosed with pseudoaneurysm of the popliteal artery.

Cystic adventitial degeneration of the popliteal artery: lectin-histochemical study.

A case of cystic adventitial degeneration (CAD) of the popliteal artery is presented. Histologically the cyst appeared localised in the adventitia, outside the elastic lamina. A lectin-histochemical study evaluated the following peroxidase conjugated lectins: Peanut agglutinin, Concanavalin A, Ulex Europaeus (UEA I) and Wheat Germ Agglutinin. The lack of UEA I reactivity excluded an arterial origin of the cyst. Moreover, the lectin binding pattern of CAD appeared to be similar to the reactivity pattern of normal synovia.

Future perspectives in the treatment of femoro-popliteal arterial occlusions.

Femoro-popliteal occlusive disease represents the most frequent localization of atherosclerosis in the lower extremities. Treatment of this disease has changed remarkably in the last decade. A definite treatment strategy has still to be established. The pathophysiology is described. A general overview of the state-of-the art treatment modalities and the most recent developments is given. This is divided into non-interventional preventive and supportive therapy, endovascular interventional therapy, and surgical interventional therapy. The development of medical therapy has expanded enormously and is progressing still. In the wide range of interventional treatment modalities, there has been a change from invasive bypass surgery to more refined techniques like endarterectomy and percutaneous endovascular therapy. This trend towards restoring the patency of the artery using the vessel wall itself as a conduit, leads to a term encompassing all these treatment modalities, known as restorative intervention. Peri-procedural risks of restorative interventions are of a much lesser degree compared to bypass surgery. Reports of patency rates show a steady increase. It is expected that patency rates will eventually equal or even surpass those of bypass surgery. In conclusion, a treatment strategy for femoro-popliteal occlusions in the future is proposed as follows: the first line of interventional therapy in femoro-popliteal occlusions should be a restorative intervention. With adequate adjuvant medical therapy and sufficient monitoring, this will be the definite treatment for the majority of patients. Bypass surgery should be regarded as the second line of interventional therapy and should be reserved for those patients in whom restorative interventions fail.

Complications after percutaneous transluminal angioplasty in the iliac, femoral, and popliteal arteries.

During a 5-year period percutaneous transluminal angioplasty (PTA) was attempted in 134 iliac, femoral, and popliteal arteries in 127 patients. Complications were systematically registered and classified as major, minor, and radiologic. Seventeen major complications (12.7%), including three deaths, occurred, as well as five minor (3.7%) and 13 radiologic complications (9.7%). The last group showed no clinical symptoms. The frequency of complications in our series is high compared with that found in a survey of 13 studies with 2043 patients. The most marked discrepancy was our high frequency of septic symptoms. A mortality rate of 2.2% was also higher in our series, but we have consequently registered the 30-day mortality rate to make comparisons with surgical series relevant. Radiologic alterations are usually not reported in other series probably because they are regarded as a part of the method, but we consider these alterations as potentially dangerous and important to report because they can result in clinically relevant complications. Because of the complications PTA should only be performed in centers in which complications can be optimally treated.

[False aneurysm of the popliteal artery after implantation of an alloplastic bypass: surgical treatment].

The false aneurysm of the popliteal artery is a rare complication in bypass surgery after the implantation of an alloplastic prosthesis. We saw this complication in 0.7 % of our patients. We report on 6 cases successfully treated by surgery. The false aneurysm developed within 2 weeks up to 44 months following the operation. We describe the symptoms, the details of diagnosis and of surgical treatment. In most cases the false aneurysm is symptomatic and should be operated immediately.
