Femoral aneurysms are rare and even more so in the superficial femoral artery. These account for only 3% of all peripheral aneurysms. The objective of this study was to present the case of an true isolated aneurysm in the superficial femoral artery associated with blue finger syndrome. A 75-year-old male patient, smoker, with a personal pathological history of arterial hypertension, is reported to be urgently referred from his health area for presenting changes in coloration (cyanosis), coldness and pain in the sole and toes of the right foot (distal microembolisms). The contrasted computed tomography showed an isolated aneurysm in the superficial femoral artery of 4.5 cm transverse diameter. It was decided to operate on the patient and aneurysmectomy was performed with interposition of prosthetic graft with polytetrafluoroethylene, with a configuration of termino-terminal anastomosis. He had a satisfactory immediate and late postoperative clinical evolution. Among femoral aneurysms, those affecting the superficial femoral artery are less described and can be complicated by thrombosis, distal embolization, or rupture. There is a high consensus for their repair by removing the embolic source, preventing thrombosis, treating rupture, eliminating any mass effects and restoring perfusion of the distal limb. Since blue finger syndrome may be the first manifestation of this pathology, its rapid recognition, early diagnosis of the emboligenic source and medical-surgical treatment can prevent major amputation or death of the patient.
