Femoro-popliteal artery thrombolysis with intra-arterial infusion of recombinant tissue-type plasminogen activator--report of a pilot trial.

Recombinant tissue-type plasminogen activator (rt-PA) was infused at a rate of 10 mg/h into 50 thrombosed femoral and popliteal arteries. Patency was restored in 43 but a secondary angioplasty led to 2 reocclusions and in 3 patients early rethrombosis occurred. A favourable clinical result was thus obtained in 38 patients (76%). Thirteen bleeding complications occurred in 10 patients, mainly haematomas at puncture sites. One patient required blood transfusion for gastro-intestinal bleeding from a previously unknown ulcer. The angiographic recanalisation rate in 16 patients who received a slower infusion of rt-PA (5 or 3 mg/h) was 94% and the clinical success rate in this series was 81%. However, the incidence of bleeding complications was not decreased by the slower infusion rate. The data obtained confirm the feasibility of rt-PA thrombolysis in peripheral arterial thrombosis and warrant a comparative study with streptokinase.

[Hypertrophy of the gastrocnemius muscles: possible etiology of the popliteal artery entrapment syndrome?].

Excessive hypertrophy of the both heads of gastrocnemius has been reported as a possible etiology of a popliteal artery entrapment syndrome. However, this syndrome is rather unusual among all those young adults and athletes with hypertrophied gastrocnemius. An other factor must exist in addition of hypertrophy. We describe a patient presenting a more cranial migration of the both heads of gastrocnemius with a shorter and more proximal tendinous attachment above the femoral epicondyles. Thus, excessive hypertrophy of the both heads of gastrocnemius may be in fact the cause of a popliteal artery entrapment syndrome when there is a congenital abnormality of muscular migration.

[Aneurysms of the popliteal artery. Intravascular bypass using the internal saphenous vein].

We used the internal saphenous vein to create an intravascular bypass for the treatment of aneurysms of the popliteal artery. The saphenous vein was positioned within the lumen of the aneurysmal popliteal artery and in the superficial femoral artery at its origin. Two end-to-end anastomoses were made including the venous wall within the suture. This new surgical technique is based on 3 criteria. i) anatomic: the venous bypass follows the exact path as the artery since it is situated within the lumen; ii) haemodynamic: end-to-end anastomoses are used to avoid turbulence created with end-to-side sutures; iii) histologic: the venous endothelium protects better against thrombus formation ensuring good long-term permeability.

[Atherectomy with over-the-wire type catheter for femoro-popliteal artery stenosis: initial and eight month follow-up results].

Percutaneous atherectomy using Atherotrack was performed in 5 patients with symptomatic femoro-popliteal artery stenosis. All patients were men and ages ranged from 37 to 70. Four lesions were atherosclerotic and 1 lesion was post-operative anastomotic stenosis following traumatic popliteal artery injury. There was no technical failure and all lesions were successfully dilated with no or minimal residual stenosis. API returned within normal limit and patients were symptom-free immediately after the procedure. We experienced no major complication related to this procedure. Excised specimen included thickened fibrous intima, atherosclerotic materials, calcification, internal elastic lamina and fibrous media. Follow-up DSA 5 months after procedure showed good patency in 4 cases, and they remained free from symptoms in this follow-up period. In those patients, lesions were generally short and eccentric, run-off was good, and only thickened intimal tissue was obtained. Those factors seem to promise long-term patency and to be good indications of atherectomy. Restenosis as well as recurrence of claudication, however, developed in one patient with DM, who had long, tight, complex stenosis and poor run-off. Considerable amount of medial tissue was found in this specimen. We suspect that those factors were associated with reduced long-term patency rates.

Improved limb salvage in popliteal artery injuries.

This study reviews the recent experience with popliteal artery injuries at the Massachusetts General Hospital. Twenty-two patients suffered 24 injuries. The overall limb salvage was 83%. Blunt trauma accounted for 19 of the cases and was associated with femur fractures, knee dislocations, and tibia-fibular and plateau fractures: four amputations (21%) resulted. There were five penetrating injuries from three gunshot wounds, one stab wound, and one laceration: no amputations occurred. The major factor in the amputated limbs was delay in diagnosis and therapy of the arterial injury associated with blunt trauma. Arterial disruption secondary to penetrating injuries was recognized more quickly and had a better outcome. A higher index of suspicion in blunt trauma may improve results. Recommendations for therapy are: arterial reconstruction should generally precede orthopedic operation. Venous ligation was not associated with increased limb loss, but we recommend repair if possible. Arterial repair includes thrombo-embolectomy in distal arteries. If necessary, reverse saphenous vein is grafted. When operation is unsuccessful, revision should be performed.

Popliteal artery aneurysm.

Fourteen patients with atherosclerotic aneurysms of the popliteal artery, which were bilateral in 13, have been managed in a vascular unit where ultrasound, xerography, and isotope angiography are available for investigation. Although these methods are useful in confirming a suspected diagnosis, they cannot replace an awareness of the condition and clinical methods of examining the ischaemic lower limb. Reconstructive vascular surgery was effective in preserving the presenting leg in 5 cases and amputation was needed in 6, while no operation was needed in 3. Elective arterial surgery was carried out on the asymptomatic contralateral leg in 7 cases with good results and this active approach to treatment is recommended.

[Injury of the popliteal artery].

Injuries to the lower limbs are now commonplace, in particular due to the increased number of car accidents, work accidents, injuries from knives or fire arms, or sporting injuries. The popliteal artery is involved in 6% of all these injuries. A clinical case is described of a subject who was injured, causing laceration to the popliteal artery, and brought to our attention six months after the event.

[Complicated course of a compression syndrome of the popliteal artery in a 36-year-old patient].

The popliteal entrapment syndrome is an entity increasingly reported over the past few years. Anatomical variations should be considered if a localized stenosis or occlusion of the popliteal artery is diagnosed in a young, otherwise healthy individual. This case report documents a complicated course of the disease in a young man in whom diagnosis was made only after futile attempts of intraarterial lysis and dilatation at the time of a second operation. A complex crural reconstruction was necessary in order to revascularize the treatment limb.

[A patient with cystic adventitia degeneration and entrapment syndrome of the popliteal artery].

Adventitial cystic disease and entrapment syndromes of the popliteal artery are rare causes of ischemia in the lower leg in younger patients without cardiovascular risk factors. The 38-year-old male patient described in this case report showed both types of these rare abnormalities in the same vessel, both usually requiring surgical revision even in causing only few symptoms.

Popliteal artery entrapment. (Report of a case).

A case of popliteal artery entrapment syndrome caused by an anomalous gastrocnemius muscle is described. The diagnosis, made before operation, was facilitated mainly by the presence of a "hot knee" in the affected leg. The etiology of this clinical sign is described and its diagnostic value, especially in obscure cases is accentuated. In this respect the usefulness of thermometric study and of thermography is presented. The literature of the condition is reviewed.

Infective aneurysm of the popliteal artery due to Salmonella enteritidis.

Infected aneurysms of the popliteal artery are rare and Salmonella enteritidis infection in this site has not been previously reported. In the case reported herein, septic thrombophlebitis was found to be in contact with the aneurysm. Preoperative diagnosis was made through arteriography, computed tomographic (CT) scan, and positive blood cultures. The infected aneurysm was treated by resection without any reconstruction while phlebitis was treated by thrombectomy. Appropriate antibiotic therapy was administered. The patient made an uneventful recovery.

Adventitial cystic disease of the popliteal artery communicating with the knee joint. A case report.

We describe the case of a patient with adventitial cystic disease of the popliteal artery in which a direct anatomic communication between the cysts and the nearby knee joint was demonstrated by magnetic resonance imaging and confirmed by surgery. This unusual observation could shed some light on the much debated question of the cause, the pathogenesis, and the management of the affection. Moreover, it emphasizes the importance and the role of magnetic resonance imaging in the diagnosis of adventitial cystic disease of the popliteal artery.

Cystic adventitial disease of the popliteal artery. Clinical aspects and etiology.

Cystic adventitial disease of the popliteal artery is a rare and benign disease. The appearance of claudication in a young male nonsmoker and the typical angiographic findings usually confirm the pathology. The treatment of choice is incision evacuation of the cyst. Long-term follow-up of two cases proved to be excellent with this therapy. A saphenous bypass graft provides a good alternative if incision evacuation fails to restore good peripheral pulses. The etiology of this lesion proves to be similar to a ganglion and is well demonstrated in two cases.

Acute popliteal artery occlusion after arthroscopic posterior cruciate ligament reconstruction.

Arthroscopic posterior cruciate ligament reconstruction may carry certain risks of complications, including injury to the neurovascular structures in the popliteal region. Acute occlusion of the popliteal artery, a limb-threatening complication, was reported after total knee arthroplasty. We report a case of acute popliteal artery occlusion after arthroscopic posterior cruciate ligament reconstruction. The possible causes included underlying artherosclerosis, the use of pneumatic tourniquet, surgical manipulation, and arterial spasm. Early diagnosis and prompt surgical treatment are the keys to success in the treatment of this limb-threatening complication. Spontaneous resolution of the thrombus such as is reported in this case is exceptional.

Community-acquired methicillin-resistant Staphylococcus aureus endocarditis with septic embolism of popliteal artery: a case report.

A 20-year-old man presented with a 14-day course of fever. Physical examination showed petechiae of the conjunctivae, Janeway lesions on both hands, a grade III/VI systolic murmur over the apex, pulseless dorsal pedal artery and posterior tibial artery of the right leg, and a pale right foot. Femoral arteriogram of the right leg revealed total occlusion of the popliteal artery with collateral circulation of the posterior tibial artery. Transthoracic echocardiogram showed trace mitral regurgitation. Embolectomy of the right popliteal artery was done, and penicillin and gentamicin treatment was administered. However, postoperative fever developed intermittently. Transesophageal echocardiogram disclosed vegetation over the anterior leaflet of the mitral valve. Methicillin-resistant Staphylococcus aureus (MRSA) was isolated from all three cultures of blood drawn at admission and from the septic embolus during operation. He had neither evidence of underlying heart disease, nor history of intravenous drug abuse or hospitalization. Exploratory cardiotomy with removal of vegetation on the mitral valve was performed followed by a 4-week treatment with intravenous vancomycin. After discharge, he was well at 2-year follow-up.

[Surgical treatment of infectious aneurysm of the popliteal artery. Description of a case caused by Campylobacter jejuni and a review of the literature].

The authors describe a case of mycotic aneurysm of the popliteal artery secondary to Campylobacter jejuni-derived infectious endocarditis treated by excision and in situ femoro tibial venous bypass, and take the opportunity to review 14 literature cases of infectious aneurysm of popliteal artery. This diagnosis is most frequently evoked by the development in an infectious setting of a throbbing inflammatory mass in the popliteal fossa. Management is aimed at controlling the infection and insuring proper distal vascularization. Eradication of the infection rests with the excision of the aneurysm and adequate antibiotherapy for at least 6 weeks. Distal vascularization is best provided (2 cases) by extra-anatomical bypass. However, in situ bypassing (9) is possible provided apyrexia and negative blood cultures have been obtained by preoperative antibiotherapy. The material used must be a venous autograft, whenever possible.

Endovascular stent-grafts for aneurysms of the femoral and popliteal arteries.

Our objective was to investigate the preliminary use of endovascular stent-grafts for the treatment of femoropopliteal artery aneurysm. Ten patients with an aneurysm of the femoropopliteal artery referred for endovascular treatment were investigated. The series consisted of patients with a true aneurysm of the superficial femoral artery (n = 2); a true aneurysm of the popliteal artery (n = 4); an aneurysmal dilatation of a Biograft bypass (n = 2); a false aneurysm of the superficial femoral aneurysm (n = 1); and a false aneurysm of a composite bypass (n = 1). In 8 of the 10 patients the stent-graft was composed of one or more Palmaz stents sutured to an ePTFE tube graft; in the other 2 patients a venous covering was used in combination with Palmaz stents. The procedure was guided by angiography and intravascular ultrasound. The results of our investigation showed that endovascular stent-grafting of aneurysms of the femoropopliteal artery is a feasible but experimental technique that should be restricted to a selected group of patients.

High and low lateral approaches to the popliteal artery.

Using a series of 20 dissections and two anatomic transverse sections of a lower limb, the authors investigated the lateral approaches to the popliteal artery. The high lateral approach (above the knee) is not very aggressive and gives access to the retro-genicular part of the popliteal artery. After cutaneous and fascial incision, a simple gap between the vastus lateralis and biceps femoris mm. allows easy exposure of the popliteal vessels after backward retraction of the sciatic nerve. The low lateral approach to the artery (below the knee) is very aggressive for the vessels, nerves, and ligaments of the area. It involves the resection of the upper fourth of the fibula and the isolation and protection of the common peroneal nerve Nevertheless, these lateral approaches must be known and used when classic approaches (medial and posterior) are impossible.
