Extracranial vertebral artery aneurysms are rare complications from trauma and multiple diseases. However, the difference between clinical and surgical pro les is not well understood. ObjectiveTo investigate the clinical and interventional outcomes following extracranial vertebral artery aneurysms (VAA) treatment through a systematic review of the literature to date. MethodsAn electronic database search for full-text English articles was conducted following PRISMA guidelines. The search yielded results on clinical and surgical outcomes for extracranial VAAs. These results included patient-speci c risk factors, indications, and techniques. ResultsOur literature search yielded 561 articles, of which 36 studies were quali ed to be included in the analysis. A total of 55 patients with multiple various extracranial VAA incidents were included. The mean age of subjects was 42 years (ranging from 13 to 76 years), and most patients were males (71%, n = 39).Blunt trauma was the most frequent risk factor for extracranial VAA formation (35%, n = 19). The majority of aneurysms (60%) were dissecting in nature. The most common form of treatment for extracranial VAAs was a ow diverter (24%, n = 13). Overall, ve (9%) patients had long-term adverse neurological complications following intervention with 5% (n = 3) mortality, 2% (n = 1) resulting in unilateral vocal cord paralysis, and 2% (n = 1) resulting in a positive Romberg sign. The mortality rate is 15.7% in the surgical group, whereas the endovascular treatment did not result in any mortality. ConclusionThe endovascular approach is a safe and effective treatment of extracranial VAAs due to its relatively low overall complication rate and lack of resulting mortality. This contrasts with the surgical approach, which results in a higher rate of complications, recurrence, and mortality outcomes. An understanding of the factors and clinical outcomes associated with the incidence of extracranial VAAs is essential for the future improvement of patient outcomes.

Introduction: Extracranial vertebral artery aneurysms are rare complications from trauma and multiple diseases. However, the difference between clinical and surgical profiles is not well understood. Objective To investigate the clinical and interventional outcomes following extracranial vertebral artery aneurysms (VAA) treatment through a systematic review of the literature to date. Methods An electronic database search for full-text English articles was conducted following PRISMA guidelines. The search yielded results on clinical and surgical outcomes for extracranial VAAs.

Blunt trauma was the most frequent risk factor for extracranial VAA formation (35%, n = 19). The majority of aneurysms (60%) were dissecting in nature. The most common form of treatment for extracranial VAAs was a flow diverter (24%, n = 13). Overall, five (9%) patients had long-term adverse neurological complications following intervention with 5% (n = 3) mortality, 2% (n = 1) resulting in unilateral vocal cord paralysis, and 2% (n = 1) resulting in a positive Romberg sign.

Aneurysms in the V1 segment of the extracranial vertebral artery are extremely rare. Furthermore, half of the cases are giant aneurysms larger than 25 mm. This study reports a case of unruptured giant V1 aneurysm of the right vertebral artery that was successfully treated with endovascular coil embolization. An 85-year-old woman experienced dizziness sporadically. Magnetic resonance imaging demonstrated a mass in the right subclavian region. Radiological examinations showed an aneurysm originating from the V1 segment of the right vertebral artery. The aneurysm was successfully embolized with platinum coils, with preserved patency of the vertebral artery. Although aneurysms in the V1 portion of the vertebral artery are extremely rare, there is a possibility of thrombosis or rupture. Endovascular treatment such as coil embolization may be effective for a V1 vertebral artery aneurysm.
