Surgical treatment of spindle aneurysms in V4 segment of vertebral artery / 中国医师进修杂志

ABSTRACT

Objective To explore the surgical treatment of spindle aneurysms in V4 segment of vertebral artery. Methods The clinical data, surgical methods and prognosis of 6 patients with V4 spindle aneurysms of vertebral artery admitted from 2011 to November 2018 in Sanbo Brain Hospital were retrospectively analyzed,Results There were 4 males and 2 females aged from 45 to 65 years. Aneurysm rupture and bleeding occurred in 3 cases. Far lateral approach was used in all patients. One case was clipped with window aneurysms, 2 cases were treated with occipital artery (OA)- posterior inferior cerebellar artery (PICA) bypass, and 3 cases were treated with vertebral artery occlusion. Postoperative patients were generally in good condition. Postoperative CT arteriography confirmed that the bypass vessels were unobstructed in 2 cases. All vertebral aneurysms were treated satisfactorily and PICA arteries were preserved. Tracheotomy was performed in 5 patients (1 case was incised before operation). Three patients were removed 3 months after operation. The Glasgow Prognosis Score (GOS) was 4 points. Long-term tracheotomy was performed in 1 case, and GOS score was 3 points. Two patients died 4 months and 3 years after operation. Conclusions Craniotomy is an important method for the treatment of spindle aneurysm of V4 segment of vertebral artery. Different surgical methods should be selected according to the size of the aneurysm, the relationship between the location of the aneurysm and PICA, and the compensation of the vertebral artery.
