Posttraumatic Vascular Anomalies in Hand Surgery—A Case-based Approach

Abstract

Summary:. The field of vascular anomalies (VA) has been subject to changes during the last few decades. The current classification of the International Society for the Study of Vascular Anomalies (ISSVA) offers a simple diagnostic structure. Hand surgeons commonly appear to have limited exposure to VA. Already recognized for more than 120 years, pyogenic granuloma (PG) is by far the most commonly described VA by different disciplines with accordingly diverse treatment strategies and theories behind it. Arteriovenous fistula (AVF), venous aneurysms (VAN), and venous malformations (VM) are, however, rare in hand surgery. With a compilation of four illustrative cases of posttraumatic entities such as AVF, VAN, VM, and PG, we would like to highlight possible daily exposure to VA in the general hand surgery practice. We discuss diagnostic and therapeutic options as well as the current literature with focus on posttraumatic VA.
