“…The VA has fewer critical perforators, and FD deployment in the VA is always considered a safe choice. However, in theory, because the occlusion of an unpaired ASA can result in medial medullary syndrome, FD deployment in the VA still causes concern regarding medullary ischemia from ASA ostia coverage ( 101 , 102 ).…”

The cervical anterior spinal artery (ASA) is a very important artery arising from the intracranial vertebral artery (VA). It can play different roles in endovascular treatment (EVT) of spinal vascular diseases. The current understanding of these roles is incomplete; therefore, we performed this review. We found that cervical ASA can be involved in many spinal vascular diseases, such as arteriovenous fistula (AVF), arteriovenous malformation (AVM), and aneurysm, and can serve as a collateral channel in proximal VA occlusion. In AVF and AVM, when the cervical ASA is involved, it often plays the role of an accomplice or victim because it acts as the feeder or as a bystander that does not provide blood flow to the AVF and AVM. In cervical ASA aneurysm, the ASA is a victim. During EVT of VA aneurysms or stenoses, the cervical ASA ostia can be covered or occluded, resulting in ASA ischemia. In this situation, the ASA is a victim. In VA occlusion or the subclavian steal phenomenon, the cervical ASA can serve as a collateral channel to provide blood flow to the posterior circulation. In this case, the ASA plays the role of a friend. According to the role of the cervical ASA in spinal vascular diseases, EVT should be determined “case by case.” Most importantly, when EVT is performed to treat these diseases, the cervical ASA axis must be preserved. Therefore, understanding the role of the cervical ASA in spinal vascular diseases is crucial.

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.
