Clinical snapshot “Volleyball” Aneurysm of the Posterior Circumflex Humeral Artery
A 34-year-old male patient, a volleyball player, exhibited aneurysm embolization of the posterior circumflex humeral artery (PCHA; white asterisk). Since the patient initially presented with acute ischemia of the hand, surgical treatment by means of embolectomy was necessary. Although PCHA aneurysms are on the whole extremely rare, they are typical in overhead athletes, such as volleyball players. The most likely pathomechanism involves hyperabduction, external rotation, and extension of the shoulder in the above-mentioned group, leading to artery compression and potentially to subsequent aneurysm formation. A superimposed thrombus may be “milked out” and embolize. For the young, active patient, the decision was taken to perform open surgical aortic repair by proximal/distal ligation. The patient was discharged 5 days postoperatively and has since resumed regular sports activities.
