ABSTRACT

Introduction: aneurysms are focal and permanent dilations of an artery; in pseudoaneurysms, the normal layers of the blood vessel are replaced by fibrous tissue. Due to their low incidence, as well as the diagnostic and therapeutic challenge they represent; our objective is to present the clinical case of a pseudoaneurysm of a digital artery of the hand and to carry out a systematic review of this pathology. Material and methods: literature search in Medline, using the terms "digital artery" and "aneurysm." Studies of vascular dilation pathology affecting the hand and fingers were incorporated. Studies with pathology of proximal involvement of the hand were excluded. Case presentation: a 79-year-old female patient who, after a sharp force trauma to the fifth finger of the left hand, develops a rapidly growing necrotic tumor. She had ultrasound and angiography that suggested hematoma. Surgical management was decided, during which it was observed that the tumor involved ulnar collateral digital artery of the fifth finger. The lesion and the arterial segment involved were resected. Post-surgical course without complications. The histopathological diagnosis of pseudoaneurysm of the lesion was confirmed. Discussion: traumatic etiology is the most frequent cause of digital aneurysms. Risk factors for pseudoaneurysms include sharp force trauma and alterations of the coagulation pathways, as in the case presented. Conclusion: the pseudoaneurysm of a digital artery is a rare pathology with great variability of therapeutic management. Surgical resection of the lesion with vascular flow reconstruction is the recommended treatment.
