Favorable Outcomes of an Infected Common Femoral Artery Aneurysm Triggered by Scabies-related Cellulitis after Elective Surgery

Abstract

The patient was a 52-year-old man diagnosed with diabetes but had not received medical care. Blood tests indicated leukocytosis and elevated HbA1c levels. Contrast-enhanced computed tomography (CT) revealed abnormal soft tissue shadows surrounding the right common femoral artery. The patient was then diagnosed with right femoral cellulitis and an infected femoral aneurysm. Antibiotic therapy and diabetic treatment were initiated accordingly. On the eighth day of hospitalization, edema appeared in the right lower extremity, and CT demonstrated femoral artery transformation into a pseudoaneurysm with an associated flattened femoral vein. Given the inadequate glycemic control and active infection, the decision was to defer surgery until euglycemia was achieved. After the cellulitis resolved, a dermatologist identified scabies in the right inguinal region, necessitating further surgery postponement due to the required isolation period. Following the isolation period, a preoperative CT scan revealed a thrombus in the right femoral vein. On the 35th day of hospitalization, the patient underwent an aneurysmectomy and a bypass procedure involving the right external iliac artery and superficial femoral artery, accompanied by venous ligation. The patient experienced a favorable postoperative recovery and was discharged on the 28th day to continue recuperation at home.
