“…For direct surgery, multiple studies have reported PAO with bypass, [2,5,8] but our case was the first, in which surgical clip occlusion was executed without bypass because the unaffected VA was intact. According to Morgan and Sekhon, [8] the reason that direct surgery was selected was that the dissection ranged from the VA ostium to the V2 segment.…”

“…Seven cases of traumatic EVAD treated with PAO were reported [Table 1]. [2,4,5,[7][8][9] Most cases occurred in younger patients, on the right side and on the V2 segment of the VA dissection. However, our case was the only one in which the cerebral infarction recurred after medical therapy.…”

“…[1,3,6] Surgical treatment is suggested for patients with traumatic EVAD accompanied by recurrent cerebral ischemia despite medical therapy. [5,7] Endovascular or direct surgery is selected on an individual basis.…”

“…However, our case was the only one in which the cerebral infarction recurred after medical therapy. Endovascular and direct surgery was performed in three [4,7,9] and five [2,5,8] cases, respectively. Cohen et al [4] reported an involved coil embolization of the right VA. A stent was used to treat the left VA due to bilateral EVAD.…”

“…[1,3,6] Despite the continuation of medical therapy, if a recurrent ischemic stroke occurs, which often presents as transient ischemic attacks or aneurysms, surgical parent artery occlusion (PAO) is performed. [2,4,5,[7][8][9] We report a rare case of traumatic EVAD with recurrent cerebral infarction. e patient was effectively treated with surgical clip occlusion of the V3 segment of VA and had no recurrence of cerebral infarction.…”

Background: Recurrent cerebral infarction caused by traumatic extracranial vertebral artery dissection (EVAD) is treated medically and surgically. We report a case of EVAD that was treated using surgical clip occlusion of the V3 segment to prevent recurrent cerebral infarction. Case Description: A 48-year-old man was admitted for a cerebral infarction caused by EVAD and was treated using 200 mg/day cilostazol. Afterward, the cerebral infarction recurred. Digital subtraction angiography revealed that initial severe stenosis of the VA ostium resulted in the final occlusion and that collateral vessels to the VA remained. We continued antiplatelet therapy, but the cerebral infarction recurred due to thromboembolism of the collateral vessels. Parent artery occlusion was planned. We exposed the V3 segment of the VA and clipped it to prevent the recurrence of cerebral infarction. Conclusion: Surgical clip occlusion of the V3 segment was effective for treating recurrent cerebral infarction caused by traumatic EVAD that had remained an issue despite continuing medical therapy.

Objective: Occipital artery anatomy should be well known in order to minimize complications that may occur in the occipital artery, which is closely adjacent to this nerve, during greater occipital nerve blockade. In this study, it is aimed to evaluate the morphometric relationship of the occipital artery with neighboring anatomical structures in order to prevent damage during clinical applications. Materials and Methods: This study was carried out using CTA images of the head and neck region of patients who applied to Balikesir University Medical Faculty Training and Research Hospital for various reasons between 2015 and 2021. In the study, CTA images of 85 individuals aged 35-63 years were evaluated morphometrically using Radiant DICOM viewer 64-bit computer software. The obtained data were transferred to SPSS Version 25 software and analyzed quantitatively. Results: According to the results obtained from the study, no significant difference was found between the variables and genders. As the age of the individual increased, it was observed that the left occipital artery was located more inferolateral to the external occipital protuberance. As a result of the data obtained, a negative correlation was observed between the closest distance between the right OA-ML and the right EOP-ML and the spinous process of the seventh cervical vertebra. Conclusion: In line with the average values obtained as a result, it is thought that an injection to the central point of the triangular area, which is formed as a result of combining the reference points in the posterior occiput, may be safer in order to protect the occipital artery.
