Zusammenfassung:Anastomotic pseudoaneurysms of interposition vein grafts are a rare entity that requires urgent management to prevent life-threatening complications, such as rupture and thromboembolism, especially when involving the carotid arteries. As these are rare complications and literature is sparse, we believe that this case report can aid the decision-making process in similar circumstances. A 49-year-old Ukrainian male patient presented with a false aneurysm of both distal and proximal anastomosis of an interposition vein graft between the common carotid artery and the internal carotid artery, which was previously performed as a bailout procedure after the patient developed a complication of carotid surgery. The patient was successfully treated with extra-anatomical interposition of a vein graft from the subclavian artery to the remnant of extracranial internal carotid artery and en bloc excision of the previous vein graft with the false aneurysms. Mycotic anastomotic pseudoaneurysms following carotid endarterectomy represent a rare yet serious complication in vascular surgery that requires urgent treatment. While endovascular techniques could represent an alternative option, open surgical repair is still the standard of care for this pathology, offering advantages in preventing postoperative ischemic complications and ensuring optimal long-term outcomes. The open approach provides direct visualization of the pseudoaneurysm. It allows the meticulous debridement of the infected tissues and an accurate reconstruction of the arterial wall with autologous or synthetic grafts. In light of the substantial evidence supporting its superiority, open surgical repair should remain the preferred approach in addressing mycotic anastomotic pseudoaneurysms following carotid endarterectomy. Future research should continue to explore advancements in other surgical techniques and refine treatment strategies to enhance patient outcomes in this challenging clinical scenario.
