HighlightsPseudoaneurysms of the deep femoral artery are uncommon and occur as a late complication of various traumas.We report two cases of profunda femoris artery injury which presented as false aneurysm secondary to penetrating trauma.As these cases illustrate, the diagnosis of pseudoaneurysm of deep femoral artery following trauma and orthopedic procedures requires awareness and a high index of suspicion.

IntroductionSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is currently known to lead to high rates of thrombotic complications. Of those, acute limb ischemia (ALI) was most frequently reported. Several case reports or case series had already described high mortality and amputation rates. The purpose of our study was to highlight the epidemiological, clinical, and management characteristics of coronavirus disease 2019 (COVID-19)-related ALI patients. MethodsThis was a monocentric, observational, and retrospective study. Records of all patients ≥18 years of age admitted with ALI and a confirmed diagnosis of COVID-19 infection between March 2020 and December 2021 were retrospectively examined. Data collected included demographics, co-morbidities, biological findings, COVID-19 pneumonia and ALI severity, anatomical location of arterial thromboembolism, treatments, and outcomes. ResultsDuring the study period, 22 patients with ALI infected with COVID-19 were evaluated. The median age was 67 years (45-88) and 18 (81.8%) were men. The main comorbidities were diabetes mellitus (36.4%), smoking (22.7%), and arterial hypertension (18.2%). All 22 patients were already diagnosed positive for SARS-CoV-2. The median duration between COVID-19 diagnosis and ALI symptom onset was six days (1-13 days). The computed tomography (CT) extent of pulmonary lesions was assessed according to the French Society of Chest Imaging. The ischemic syndrome was classified on Rutherford Stage IIA (30.4%) and IIB (43.5%). Regarding thrombotic locations, ALI had occurred essentially in the lower limbs (95% vs. 5%). A revascularization procedure was performed in 14 patients (63.6%) of the patients, and primary amputation was unavoidable in five patients (22.7%). Three patients (13.6%) did not undergo operative management, two because of their hemodynamic instability and one rejected surgery. We performed 23 revascularization procedures for 14 patients and three primary amputations. Thromboembolectomy (TE) was the technique of choice (92.8%). Below-the-knee (BTK) femoropopliteal bypass was performed in one patient. Selective tibial vessel thrombectomy was performed in four patients (28.6%). The mortality rate was 27.3%. Among survivors, two secondary amputations were needed with a limb salvage rate of 68.2%. ConclusionBy the apparent end of the pandemic, our study further supports the increased risk of ALI in COVID-19positive patients. Moreover, the results affirm the unfavorable outcomes highly impacted by rethrombosis, reinterventions, and consequently high rates of amputations and mortality.
