ABSTRACT
BACKGROUND: This study evaluated the clinical and functional efficiency of deep femoral artery (DFA) revascularization in treating thigh claudication associated with ipsilateral internal iliac artery (IIA) occlusion. PATIENTS AND METHODS: The files of patients presenting with proximal claudication, ipsilateral IIA occlusion, and conventional surgical revascularization of DFA were retrospectively reviewed. Each patient benefited from preoperative and postoperative measurement of dynamic transcutaneous pressure of oxygen (TcPO2) and presented with preoperative proximal stress-related ischemia and with the clinical symptoms of buttock, thigh, or groin pain. RESULTS: Between May 2001 and December 2009, 23 DFA revascularizations were performed on 19 patients. Proximal stress-related pain disappeared in 17 lower limbs (74%). No postoperative thromboses were noted. Mean maximum walking distance (MWD) significantly improved (149±113 vs. 414±257 m; P<0.025), as did the ankle to arm systolic pressure index (0.71±0.17 vs. 0.90±0.19; P<0.005). Disappearance of proximal stress ischemia, revealed through postoperative dynamic TcPO2, measurement, occurred in 6 lower limbs (26%). Patency of ipsilateral superficial femoral artery, ipsilateral to the symptoms, seemed to be a predictive factor of MWD improvement (P<0.05). CONCLUSIONS: DFA revascularization is an efficient treatment for thigh claudication in case of IIA occlusion, even if the results are less satisfactory than those obtained through direct revascularizations of this artery.

BACKGROUND: The aim of this study was to evaluate the feasibility of outpatient peripheral angioplasty in patients who were treated for lower limb claudication. METHODS: Between February 1 and December 31, 2007, a monocentric observational study was carried out on 98 consecutive patients who presented with claudication (mean age: 63 years [range: 31-90]; 81 men) and were treated by using a percutaneous femoral approach for either iliac (n = 62) or femoropopliteal lesions (n = 36). Exclusion criteria were requiring a renal angioplasty or an associated surgical procedure, having a creatinine clearance value of <30 mL/min/1.73 m(2), body mass index exceeding 35 kg/m(2), and critical ischemia or vascular surgery history at the site of femoral puncture. Treatment involved manual compression and/or use of a closure system, after which the patients were made to wear a compression bandage. After 4 hours, the patients were carefully examined for the presence of a local complication (puncture site), a general complication (thoracic pain), or a complication related to the surgical procedure (early thrombosis). When no complications were detected, the patients were allowed to get up and walk. At the sixth hour, the patients were again examined for the presence of the aforementioned complications. In the absence of any complications, the patients were deemed as "fit to be discharged" and were allowed to stroll about inside the hospital. The following day, a final evaluation was carried out just before their discharge. The risk factors and comorbidities were evaluated. RESULTS: At the sixth postoperative hour, 78 patients (80%) were deemed as "fit to be discharged." The remaining 20 (20%) were deemed as "unfit to be discharged" because of either a major hematoma (n = 3, including two redo surgeries and a blood transfusion) or a minor evolutive hematoma. All the complications (n = 17) occurred before the fourth postoperative hour. Bilateral femoral puncture was the only risk factor found to be associated with contraindication to being discharged in the evening (OR = 3.8, p = 0.02). CONCLUSION: Ambulatory treatment for patients with claudication treated with an endovascular approach was possible because complications that required overnight surveillance always occurred within the first 4 postoperative hours. Bilateral femoral puncture is a potential risk factor for failure of outpatient management.
