An Aneurysmal Degeneration of Venous Bypass for Popliteal Artery Entrapment Syndrome.

Popliteal artery entrapment syndrome (PAES) is a rare condition, and its long-term outcome after surgical treatment is scarcely reported. We report the case of an aneurysmal degeneration of a venous bypass performed to treat PAES, which ultimately led to rupture. Hybrid treatment combining embolization and surgery resulted in favorable outcome. This case emphasizes the need for long-term follow-up after surgical treatment of PAES.
