Perioperative adverse events in percutaneous versus open brachial access.

OBJECTIVE: The objective of the present study was to compare the incidence of complications at the access site after percutaneous brachial access (PBA) and open brachial access (OBA) in the treatment of peripheral arterial disease. METHODS: From November 2016 to November 2021, all patients who had undergone peripheral artery revascularization with brachial access were included. The primary outcome was the 30-day rate of postoperative complications at the access site. The complications included hematoma, arteriovenous fistula, and pseudoaneurysms that had resulted in prolonged hospitalization and/or reintervention. RESULTS: Overall, 259 procedures with brachial access had been performed (PBA, n = 101; OBA, n = 158). The baseline clinical and demographic characteristics were well-balanced between the two groups. The sheath size was larger for the OBA procedures. Complications had occurred in 11 of 101 patients (11.1%) in the PBA group and 5 of 158 patients (3.2%) in the OBA group (P = .01). The mean duration of the procedure was significantly shorter for the PBA group (73.5 ± 46.5 minutes vs 101.2 ± 60.8 minutes; P = .0001). CONCLUSIONS: For patients who had undergone brachial access for peripheral vascular disease, the rate of access site-related complications was significantly lower for the patients who had undergone open access compared with that for the patients who had undergone percutaneous access.

A comparison of suprarenal and infrarenal fixation and renal volumetric analysis after endovascular aneurysm repair.

OBJECTIVE: Clinical and experimental studies of the stent-graft fixation impact on the renal volume after endovascular abdominal aortic aneurysm repair have focused on glomerular filtration rate, and the results were controversial. The aim of this study was to analyze and compare the impact of the suprarenal (SRF group) and infrarenal (IRF group) stent-graft fixation on the renal volume. METHODS: Between December 2016 and December 2019, all patients treated with endovascular aneurysm repair were retrospectively analyzed. Patients with atrophic or multicystic kidney, renal transplantation, ultrasound examination, or incomplete follow-up were excluded. The renal volume in both groups was extracted with a semiautomatic segmentation from contrast-enhanced computed tomography scan performed before the procedure, at 1 month, and at 12 months of follow-up. A subgroup analysis of the SRF group was performed in order to study the impact of the stent strut position relative to the renal arteries. RESULTS: A total of 63 patients were analyzed (SRF: 32 and IRF: 31). Demographic and anatomic characteristics were similar between the groups. The procedure contrast volume was higher in the IRF group (P = .01). At 12 months, we observed a decrease in the renal volume of 1.4% in the SRF group and 2.3% in the IRF group (P = .86). The SRF subgroup analysis showed only two patients with no stent struts crossing the renal arteries. In the remaining cases, struts crossed one renal artery in 60% of cases (19 patients) and two renal arteries in 34% of cases (11 patients). The renal volume decrease was not correlated with the presence of stent wire struts, crossing a renal artery. CONCLUSIONS: Stent graft with suprarenal fixation seems not to be correlated with renal volume deterioration. A randomized clinical trial with a higher effective and longer follow-up is needed to assess the impact of SRF on renal function.

Antegrade Superficial Femoral Artery Approach Using Manual Compression and 4-F Delivery System for Infrainguinal Occlusive Disease.

BACKGROUND: This study sought to assess the feasibility and safety of antegrade superficial femoral artery (SFA) duplex-guided puncture using a 4-F catheter sheath and manual compression for the treatment of infrainguinal occlusive lesions. METHODS: From March 2017 to March 2019, all patients who underwent endovascular treatment employing an antegrade SFA approach for femoropopliteal or below-the-knee lesions were included in this study. Follow-up included clinical and duplex ultrasound examinations at 1 month. The primary endpoint was the frequency of major complications at the puncture site. RESULTS: In all, 71 procedures were performed in 70 patients (46 men; mean age: 79.1 ± 11.5 years), most of whom presented with critical limb-threatening ischemia (n = 59; 83%). Of these 71 procedures, 35 (49.3%) were performed for isolated femoropopliteal lesions and 24 (33.8%) for multilevel lesions. The primary endpoint was observed in 4 patients (5.6%). There were 3 observed hematomas (4.2%): 2 required surgical treatment, and 1 necessitated transfusion without intervention. At 30 days, we reported 1 pseudoaneurysm (1.4%). CONCLUSIONS: Our results showed that antegrade SFA puncture is feasible and safe with duplex ultrasound guidance and use of a 4-F catheter sheath.

Epithelioid Hemangioendothelioma of the Lower Limb, Discovered by a Claudication.

Epithelioid hemangioendothelioma (EHE) is a rare case of a tumor with different clinical behaviors and a difficult anatomopathological diagnosis. The diagnosis of EHE is usually confirmed by postoperative histopathologic examination. Actually, it is a challenge to put a correct diagnosis and to propose aggressive treatment. We report a case of an EHE of the left lower limb discovered in a 53-year-old claudicant woman. Surgical resection, arterial, and venous bypass were performed. The histology demonstrated EHE with a low mitotic index, emerging for the femoral vein.
