[Femoropopliteal angioplasty: Short- and mid-term results]. / Angioplastie de l'axe fémoro-poplité : résultats à court et à moyen terme.

BACKGROUND: Percutaneous endovascular therapy is becoming a primary option for managing femoropopliteal occlusive disease. The purpose of this study was to evaluate the mid-term results of endovascular treatment of femoropopliteal arterial disease. METHODS: Femoropopliteal percutaneous transluminal angioplasty was performed on 162 consecutive limbs (160 patients) from January 2006 to January 2016. RESULTS: In our study, 87.6% of patients had critical limb ischemia. Lesions were classified as Trans-Atlantic Inter-Society Consensus (TASC) A (43%), B (43%), C (7%), and D (7%). Femoropopliteal interventions included angioplasty only in 70 cases (43.2%), and the remaining 92 (56.8%) received at least one stent. Technical success was achieved in 98.7% of patients, with three deaths and a major morbidity rate of 15%. The actuarial primary patency at 12 and 36 month was 65.4% and 40.2%, respectively, 33 peripheral reinterventions were performed after femoropopliteal axis occlusion, resulting in an actuarial primary limb preservation rate of 94.4 at 12 months. Comparison between angioplasty only and the use of stent show no difference in primary patency (P=0.832) and limb salvage (P=0.67). Negative predictors of primary patency determined by univariate analysis included popliteal location (P<0.001) and TASC D (P<0.001). However, diabetes mellitus (P=0.001) and poor run off (P<0.001) were the principal predictive factors of limb loss. CONCLUSION: Femoropopliteal angioplasty can be performed with a low morbidity and mortality. Intermediate primary patency is directly related to TASC classification and popliteal localization.

[Endovascular treatment of acute limb ischemia occurred after popliteal stent fracture]. / Traitement endovasculaire d'une ischémie aiguë survenue après fracture d'un stent poplité.

Angioplasty stenting of popliteal artery lesions is a common procedure in endovascular surgery. Stent fractures in popliteal artery maybe asymptomatic or cause restenosis, false-aneurysm or acute thrombosis. We report one case of acute limb ischemia occurred after a popliteal stent fracture placed four months earlier. The patient underwent an angioplasty stenting, completed with thrombolysis and thrombectomy. This case-report aims to illustrate complications of stent fracture in popliteal artery and possibility's to manage it by endovascular approach.

[Popliteal artery pseudoaneurysm caused by femur exostosis: A pediatric case]. / Faux anévrisme de l'artère poplitée secondaire à une exostose fémorale chez un enfant : à propos d'un cas opéré.

Exostoses, or osteochondromas are benign bone tumors that have developed on the bone surface. These benign tumors can be asymptomatic or lead to complications, for instance arterial pseudoaneurysm. We report a case of a pseudoaneurysm of the popliteal artery treated surgically in a 17-year-old girl with a solitary exostosis of the right femur. Surgery was closure of the pseudoaneurysm and a bypass using a venous graft.

[Management of popliteal artery pseudoaneurysms as a result of limb trauma and orthopedic surgery or associated with osteochondromas]. / Prise en charge des faux anévrismes de l'artère poplitée associés aux ostéochondromes et ceux dus aux traumatismes des membres ou secondaires à la chirurgie orthopédique.

Most published articles regarding popliteal artery pseudoaneurysms (PAPs) are case reports and in English language literature. In this context, no study with robust data was previously published. The exact epidemiology of these APs is not well-known and their management is not yet codified. We wanted to summarize the current knowledge on diagnostic and therapeutic features of PAPs as a result of limb trauma and orthopedic surgery or associated with osteochondromas. An electronic research on MEDLINE and EMBASE between 1953 and March 2015 was performed; using the key words "popliteal pseudoaneurysm". The referenced articles were selectively read and this systematic review included 116 articles. Patient demographics; clinical presentations; diagnostic and therapeutic features were reviewed. In sum, 122 cases were analyzed. Overall young adult (average age=30.48±21.25 years old) represented the majority of the affected population with a masculine preponderance (79%). The main etiologies included femoral exostosis (63%), followed by the orthopedic surgery (25%) and direct trauma into the knee (10%). Painful swelling (44%) and/or pulsatile mass (39%) represented the most commonly presenting symptoms. The commonest radiological investigations used included arteriography (49%) and CTA (27%). The treatment was open surgical repair (85%) or endovascular stenting graft (14%). Post-therapeutic courses were often uneventful (98%). The morbidity rate was low at about 2%. The treatment of direct post-traumatic PAPs was usually open surgical repair (83%) with saphenous vein grafting. Endovascular stenting may be an ideal option for managing PAPs following orthopedic surgery (88%). Open surgery for vascular repair and maximum exostectomy must be undertaken concomitantly in the setting of APs associated with osteochondromas.

Popliteal pseudoaneurysm and arteriovenous fistula after acupuncture.

Most popliteal arteriovenous fistula and pseudoaneurysm formation are related to trauma. Few cases have previously been reported after acupuncture therapy. Such events are typically observed when the procedure is performed by non-medical acupuncturist. They may present with acute ischemia, recent claudication, distal emboli, or less commonly rupture. Duplex ultrasound should be considered as the 1st method of investigation. Computed tomography scanning is particularly accurate in making the diagnosis. Treatment strategies consist of surgery or endovascular management. The most commonly performed surgical technique for popliteal pseudoaneurysm repair is resection with bypass grafting, whereas popliteal arteriovenous fistula are usually treated surgically with ligation and primary repair. Endovascular procedure using a stent-graft is thought to be a reasonable option for treating popliteal false aneurysm or even arteriovenous fistula. We will describe two cases of an arteriovenous fistula and pseudoaneurysm of the popliteal artery that developed after acupuncture needling in the region of the popliteal artery.
