[Complex supraclavicular false aneurysm. Case report].
The authors report the clinical case of a 29 year-old caucasian male, previously healthy, victim of traffic accident with head and chest trauma, resulting in a prolonged stay (around 60 days) in an intensive care unit. After hospital discharge, the patient noticed a slow growing of a left supraclavicular pulsatile mass, associated with pain, both local and irradiating to the left arm. The diagnostic investigation revealed a complex false aneurysm with associated arterio-venous fistulae, dissecting cervical muscle planes and involving the braquial plexus. He was submitted to surgical intervention consisting in the ligation of a scapular afferent artery and ligation of communication to the internal jugular vein, with significant decrease in the intra-luminal blood flow velocity. He was subsequently submitted to percutaneous eco-guided thrombin injection under Valsalva manouver, with complete thrombosis of the false aneurysm. There was a quick resolution of the clinical complaints and a progressive reduction of the mass volume (6 month follow-up). A discussion is made on the main features of this entity, normally its etiopathogeny, surgical management and false aneurysm exclusion by means of eco-guided injection of thrombin.
