Initial experiences with percutaneous endovascular repair of popliteal artery lesions using a new PTFE stent-graft.

PURPOSE: To report the percutaneous endovascular management of popliteal artery lesions with a new polytetrafluoroethylene (PTFE) stent-graft. METHODS AND RESULTS: Three patients have undergone endovascular treatment in the popliteal region owing to: (1) an iatrogenic false aneurysm with arteriovenous fistula, (2) entrapment syndrome, and (3) an isolated arterial aneurysm. In each case, arterial occlusion was treated initially with thrombolysis. The underlying vascular lesions then were stented using the new Hemobahn endograft, a nitinol stent covered internally with PTFE. Each percutaneous procedure was completed successfully without major complications. During early follow-up (6 to 7 months), no signs of intimal hyperplasia, occlusion, or stent migration have been observed. CONCLUSIONS: Based on these early experiences, percutaneous treatment of stenotic and aneurysmal lesions in the popliteal artery using the Hemobahn endograft appears feasible and effective. Further experience and longer follow-up are required to evaluate this new prosthesis.

[Traumatic lesion of the popliteal artery. Synthesis of our experience].

The Authors reported experiences from 26 traumas of popliteal artery; 2 are related to continuous microtrauma from exotosis; 2 vasospasms implied vascular intervention. Tibial artery bypasses with vein grafts have been advocated to obviate any exploration of popliteal hematoma. A multidisciplinary approach consisting of orthopedist, plastic and vascular surgeons should be employed.

Reconstruction of the popliteal artery after war injury.

During the war against Croatia in 1991-1992, 85 wounded with war injuries of major vessels in the extremities were admitted to the Department of Surgery, Osijek Clinical Hospital. These 85 included 13 (15.3%) wounded with injuries of the popliteal artery. In 12 cases an allograft was used as a substitute conduit. One early thrombosis and two infections occurred. Two amputations had to be performed because of massive soft tissue destruction and infection in the leg tissue. Our experience shows that an allograft is an acceptable choice for popliteal artery reconstruction in a highly contaminated war wound.

[The physiopathology and medical treatment of acute traumatic occlusion of the popliteal artery. The point of view of the anesthesiologist-resuscitator].

The acute occlusion of the popliteal artery involves: 1. A regional disease: muscular ischaemia with an increase of capillary permeability and oedema. The recovery of the circulation brings with it the formation of free radicals. 2. Sometimes, a general and metabolic illness complicates the muscular ischaemia. It associates to varying degrees: hypovolemic shock, metabolic troubles, acute renal failure, disseminated intravascular coagulation, infection. It can compromise the vital prognosis. The reanimation which completes the surgical treatment includes two stages: 1. The prehospital stage when the first imperative is to commit the patient to the vascular surgeon's care as soon as possible and in the best hemodynamic conditions. 2. The hospital stage when the therapeutic objectives are represented by: a) the treatment of hypovolemia; b) the curing of acute renal failure (bicarbonates 2 mmol.kg-1, hypertonic mannitol 1 g.kg-1; c) fight against infection; d) Heparin: 1 to 2 mg.kg-1 (if there is no counterindication); e) hyperbaric oxygen treatment in some situations. Despite the progress of reanimation, the initially intended amputation is subject to discussion in the following circumstances: crushing which in fact accomplishes an amputation, prolonged and complete ischemia lasting more than 10 to 12 hours, severe I.V.D.C., associated serious lesions (cranial traumatism, pelvis crushing).

[The short bypass in the treatment of popliteal artery occlusion].

Authors present in case report a patient with occlusion of proximal section of popliteal artery which was resolved by the reconstructive vascular surgical procedure--short femoropopliteal bypass using autolognal saphenous vein as a graft. In discussion they deal with the problem of short bypass in traumatic injured lower extremities and also in atherosclerotic or other degenerative diseases of lower extremities arteries. On the account of particulars from literature they refer to the possibility of using various autolognal venous grafts and also artificial vascular protheses. They also deal with the adjuvant medical treatment from the point of view of prevention of a favourable closure of graft and its longterm patency. They presume that the short bypass is in indicated cases mainly in highly at risk patients fully justifiable.

[Aneurysm of the popliteal artery: clinical aspects and therapy].

Experience of the operative treatment of 45 popliteal aneurysms in 41 patients is reported. The importance of immediate surgical reconstruction whenever a popliteal artery aneurysm has been detected is stressed. In fact, the patency rate of the arterial substitutes which are utilised in the reconstructive technique, and therefore the fate of the affected limbs, is chiefly based on the presence of a sufficient run off. Ischaemic complication due to peripheral embolization or sudden thrombosis of the aneurysmatic sac is very often followed by the irreversible closure not only of the tibioperoneal arteries but also of most collateral vessels.

Popliteal artery injury following fracture or dislocation at the knee. Diagnosis and management.

Fracture dislocations or dislocations of the knee can produce an arterial injury that may be difficult to evaluate clinically. Aggressive diagnosis and treatment can produce satisfactory results in both vascular and orthopedic situations if performed early after the injury. Five cases of popliteal arterial injury were seen from April 1974 to August 1976. Three cases were following posterior knee dislocation, one was a femoral fracture displacement, and one was a rotary tibiofibular displacement. Four of the patients had complete popliteal artery transection and one had intramural hematoma and spasm. Initial diagnosis of severe arterial injury, although suspicious on clinical grounds, was not conclusive. Use of a Doppler flowmeter and arteriography was essential for the diagnosis of arterial injury. Peroneal nerve injury was present in two of five patients. Vascular surgery was successful in all cases. Skeletal instability was corrected at the time of vascular exploration, usually through same incision. Leg compartment edema or hematoma was common, but responded to fasciotomy in all cases. Vein graft reconstruction was preferred to direct repair because of wall contusion and the need for additional vessel length over edematous and contused tissue. Acceptable knee stability was obtained from initial repair in all cases.

Laser-assisted transluminal angioplasty of the superficial femoral and popliteal arteries.

During an initial 1-year experience with percutaneous laser-assisted balloon angioplasty at the Vancouver General Hospital, 9 of 61 patients considered suitable for intervention because of arterial occlusive disease were selected for laser treatment. The neodymium-YAG laser with a contact sapphire tip was chosen because the probes and tips are reusable, thereby reducing the cost per patient. The patients had either severe limiting claudication or pain at rest, involving the superficial femoral or popliteal artery. One of the patients had lesions in both legs, making a total of 10 lesions. In 8 of the 10 lesions, treatment initially was successful. In the other two instances, the laser perforated the arterial wall, but the patients suffered no ill effects; repair by bypass surgery was uncomplicated. Another patient had distal thrombosis at the time of angioplasty of the popliteal artery; this responded to fibrinolytic therapy and subsequent balloon angioplasty of the peroneal artery. The initial 80% success rate was reasonable, considering that all these patients would otherwise have undergone bypass surgery. One patient had recurrent stenosis 5 months after the procedure. The other seven had good results with relief of symptoms. However, follow-up has been short (mean 4.9 months), the longest being only 11 months.

Leiomyosarcoma of the popliteal artery: case report and review of the literature.

Vascular leiomyosarcomas are rare tumors, and only 21 have been described as developing in the systemic arteries. We present a case, the sixth in the literature, of a leiomyosarcoma originating in the popliteal artery of a 67-year-old woman treated with en bloc excision of the neoplasia and the artery followed by a popliteal tibioperoneal trunk bypass. The patient then was underwent adjuvant radiotherapy and chemotherapy. After 31 months of follow-up, the patient has mild claudication but does not have either recurrence or metastasis.

Contusive trauma of the popliteal artery.

The writers have reviewed thirteen cases of contusive trauma of the popliteal artery which came under their observation. The incidence of such lesions in arterial trauma is 22 per cent. The limb was saved in 76 per cent; but the result was only functionally good in only 46 per cent. The fundamental factors for successful revascularization are early diagnosis and precise technique. The operation of choice is a by-pass using the saphenous vein from the contralateral limb; this "jumps" right over the focus of arterial contusion.

Rupture of excluded popliteal artery aneurysm: implications for type II endoleaks--a case report.

The fate of popliteal artery aneurysms after ligation and bypass is believed to be relatively innocuous. The patient presented in this report, however, experienced spontaneous rupture of a popliteal aneurysm 11 years after ligation and bypass. Magnetic resonance angiography was used to establish the diagnosis of rupture, which was subsequently confirmed at surgery. Intraoperative arteriography demonstrated persistent collateral arterial perfusion of the excluded popliteal aneurysm sac. The collateral arterial flow originated from the superior and inferior lateral genicular arteries. The persistent arterial perfusion resulted in growth of the aneurysm from 4.2 to 7.0 cm over the 11-year period. The ruptured aneurysm was successfully treated by direct arterial exposure and suture ligation of the collateral vessels performed from within the aneurysm sac. The development of popliteal aneurysm expansion and rupture as a result of collateral arterial perfusion suggests that persistent collateral perfusion of abdominal aortic aneurysms after endovascular repair (type II endoleak) may lead to aneurysm rupture. Therefore, close observation and intervention for aneurysm expansion to prevent rupture of the excluded aneurysm are warranted.

An unusual variant of popliteal artery entrapment.

A 43-year-old woman presented with incapacitating exertional pain in the right foot, ankle, and lower calf of 1 years' duration following a minor ankle sprain. Evaluation by several physicians had been inconclusive. Physical examination identified normal pedal pulses at rest but obliteration of pulses with active plantar flexion. Segmental pressures were normal at rest and duplex scanning showed occlusion of the popliteal artery with active plantar flexion. The findings were confirmed by arteriography despite a normal course of the popliteal artery. Magnetic resonance imaging (MRI) showed no muscular abnormality. At exploration entrapment was noted to be the result of compression by branches of the sural nerve and vein as they coursed medially inserting into the medial head of the gastrocnemius muscle. Division of the neurovascular bundle resulted in complete resolution of symptoms and arterial compression on duplex examination postoperatively. This case was unusual because of the patient's age, sex, and the pathologic findings that had not been previously reported. In this case MRI was not useful in demonstrating a muscular or neurovascular bundle abnormality, supporting the use of duplex scanning as the noninvasive diagnostic modality of choice.

Long-term results of reconstructive surgery for femoro-popliteal arterial occlusive lesions.

A retrospective review of 156 reconstructions performed for femoro-popliteal arterial occlusive lesions in 141 patients was carried out in terms of the reconstructive procedure and the degree of out-flow in the distal vessel. The cumulative patency rate for 95 autogenous vein grafts was 60.7 per cent at 12 years and higher than the 27.4% patency rate for 50 endarterectomies (p less than 0.001). All of 11 synthetic bypass prostheses failed with late thrombosis within 3 years after operation. The cumulative patency rate in cases with good distal run-off vessel and those with fair distal run-off vessel were 77.1% at 11 years and 57.3% at 12 years, respectively, and these values were significantly superior to 10.3% in cases with poor distal run-off vessel. The patency rate for 41 in situ grafts was 72.2%, being superior to 65.5% for 42 free grafts.

Popliteal artery entrapment syndrome. Reconstruction of the transected medial head of the gastrocnemius muscle.

Popliteal artery entrapment syndrome (PAES) is an uncommon cause of arterial insufficiency, especially in younger, athletic patients. Surgical treatment should be performed in all cases of PAES whether the artery is occluded or not. Although transection of the compressing muscle or fascial band is required to obtain good results, controversy exists about reconstruction of the transected muscle or fascial band. We present a case of a young athlete with PAES for whom rapid recovery of the athletic activity was provided by reconstruction of the divided medial head of the gastrocnemius muscle.

False aneurysm of the popliteal artery: a rare complication of total knee replacement.

We describe a 72-year-old woman with a false aneurysm of the mid-popliteal artery after a total knee replacement, presenting with a pulsatile swelling and an audible bruit in the popliteal fossa. The diagnosis was confirmed by duplex ultrasound. Surgical repair was undertaken using a saphenous vein patch to reconstruct the arterial defect. A false aneurysm of the popliteal artery following total knee replacement is an extremely rare occurrence. To our knowledge, only four other cases have been reported in the English-language literature.
