Popliteal artery aneurysms: is endovascular reconstruction durable?

PURPOSE: To describe an endovascular method of performing femoropopliteal in situ saphenous vein (SV) bypass and popliteal artery aneurysm (PAA) embolization. METHODS: Twenty-two patients underwent PAA operations. Twelve patients had conventional SV bypasses with PAA proximal and distal ligation, whereas 10 underwent PAA embolization and an endovascular in situ SV bypass (EISB). The endovascular procedure was performed using an angioscopically guided side branch coil occlusion system. The PAAs were coil embolized under fluoroscopic surveillance. RESULTS: No deaths or wound complications occurred in the EISB group. The mean hospital length of stay (LOS) was 2.1 days. Seven EISB procedures were performed through 2 incisions, whereas 3 operations required an additional incision. One graft occluded at 3 months. All PAAs remained occluded by color-flow ultrasonography at follow-up ranging from 4 to 23 months (mean 13.6); cumulative primary patency was 89%. In the conventional bypass group, no deaths occurred, but 3 (25%) patients had wound complications. The mean LOS was 6.2 days, and 1 graft occluded, giving an 86% cumulative primary patency at 42 months. CONCLUSIONS: This minimally invasive technique obviates an extensive incision to harvest the SV and ligate the PAA proximally and distally. If long-term endovascular bypass graft patency and PAA occlusion rates prove to be similar to open operative results, the benefits of reduced wound complications, decreased hospital LOS, and increased health care savings support further investigation of this endovascular approach for the treatment of PAA.

Civilian popliteal artery trauma: an eleven year experience with 83 injuries.

Limb loss is the outcome in one third of previously reported popliteal artery injuries. This report summarizes 83 injuries with an amputation rate of 9.6%. Penetrating traumas accounted for 61 (73%) injuries and blunt traumas for 22 (27%). The incidence of amputation varied with injury type from none in seven stab wounds to three of 19 (15.8%) shotgun wounds. Distal ischemia or a pulse deficit highlights the presence of arterial trauma, and the external wound defines its site in most patients. Urgent operation is indicated by these findings. Equivocal findings suggest less compromised flow, and such patients are managed best by arteriographic confirmation before operation. Early systemic anticoagulation is indicated to decrease distal small-vessel thrombosis. The successful management of these injuries requires early and complete restoration of arterial and venous flow. This is accomplished most effectively by priority definitive reconstruction. Compulsive attention to complete restoration of arterial flow during the initial procedure is mandatory. Resection or bypass of all damaged arterial wall, liberal use of autogenous vein grafts, and repair of concomitant venous injuries enhance continued arterial patency. Routine distal catheter thrombectomy and frequent intraoperative arteriography promote and confirm complete reconstruction. Early performance of four quadrant fasciotomy is indicated if compartmental hypertension is suspected. Thorough debridement of injured and questionably viable soft tissue and adequate fracture stabilization are integral parts of successful revascularization.

[New criteria for the classification of the popliteal artery entrapment syndrome. Our experience with 14 extremities].

Authors explain their experiences with eight patients (14 affected limbs) with a popliteal artery entrapment syndrome. Classification, diagnosis and treatment were reviewed. Six limbs, with any malformation and presenting as a unique sign an important hypertrophy of their intern gastrocnemius muscle, couldn't be classified. As a result, a new classification of this pathology is presented being based on the anatomical and arteriographic aspects as well as oh the surgical indication. The important correlation between anomaly, physical complexion typus athletic and sports is noted.

Popliteal artery aneurysm treated with a minimally invasive endovascular approach: an initial report.

PURPOSE: To report a minimally invasive approach to popliteal artery aneurysm (PAA) treatment. METHODS AND RESULTS: A 48-year-old male with a 3-cm PAA was treated electively with an endovascular in situ saphenous vein bypass and transluminal antegrade coil embolization of the PAA prior to completion of the proximal anastomosis. Two short incisions at the anastomosis sites resulted in no wound complications, and the patient was discharged after 2 days. After 14 months of follow-up, the patient is asymptomatic with continued patency of the in situ bypass and occlusion of the PAA. CONCLUSIONS: This endovascular approach for minimally invasive femoropopliteal in situ saphenous vein bypass grafting appears feasible for treatment of PAAs. This method may reduce the rate of wound complications attending classic open in situ bypass grafts.

[Sub-adventitial cystic degeneration of the popliteal artery. One case (author's transl)].

On the basis of a new case of sub-adventitial cystic degeneration of the popliteal artery, the authors review the characteristics of this condition. The diagnosis may be suspected on the basis of clinical and arteriographic findings in an individual in whom the arterial system is otherwise normal. The various aetiological hypotheses are recalled. Treatment in the majority of cases consists of simple excision of the cyst. Intimal changes or segmental obstruction impose the need for resection with restoration of continuity by bypass.

Gastroesophageal tumor embolization to the popliteal arteries.

Arterial tumor embolization is an unusual cause of acute arterial occlusion and is reported primarily in the oncologic literature. We report a case of acute bilateral popliteal artery emboli from adenocarcinoma of the distal esophagus. Arterial tumor emboli are infrequent but should be considered in the differential diagnosis by the vascular surgeon caring for patients with malignancy.

[Aneurysm of the popliteal artery following arthroscopic meniscectomy].

As a result of a case report, a bibliographic review was made about false aneurysms on the popliteal arteries accidentally produced following a meniscectomy by arthroscopy. Such type of aneurysms can be defined by its false wall, its sack-shape and extensive haematoma and its clinical presentation as an acute ischemia of an extremity. It should be noted that, in all cases, an important delete in the diagnosis time was registered. It is also remarkable that an early treatment reduced the sequels of this pathology.
