Contribution of Digital Subtraction Angiogram in Diagnosis and Anatomic Recognition of Traumatic Pulsatile Mass.

Traumatic pulsating masses are difficult to make a definitive diagnosis due to anatomic variation of malformed vessels and rarely clinical incidence. It is essentially to recognizing the anatomy of such vessels, otherwise it may lead to an improperly treatment or serious complication. Digital subtraction angiogram (DSA) has a distinct advantage in both diagnosis and treatment of this subject. Here the authors report a case of venous malformation in the supraclavicular fossa with an underlying arteriovenous fistula following nonoperative management of a clavicle fracture in an adult, and discuss how to rule out potential differential diagnoses and get minimally invasive treatment with DSA.
