BackgroundWhile a growing number of reports offer evidence for the potential of drug eluting stents (DES) in treating atherosclerotic stenosis of the extracranial vertebral artery, their efficacy when compared with bare metal stents (BMS) is uncertain due to the lack of a large prospective randomized trial.MethodsA search strategy using the terms ‘stents’, ‘drug-eluting stents’, ‘atherosclerosis’, ‘vertebral artery’, and ‘vertebrobasilar insufficiency’ was employed through Medline. Five studies met the criteria for a comparative meta-analysis. The technical/clinical success, periprocedural complications, target vessel revascularization (TVR), rates of restenosis, recurrent symptoms, and overall survival were compared.ResultsThere was no significant difference in the technical success (OR=1.528, p=0.622), clinical success (OR=1.917, p=0.274), and periprocedural complications (OR=0.741, p=0.614) between the two groups. An OR of 0.388 for no restenosis in the BMS to DES arms (p=0.001) indicated a significantly higher restenosis rate in the BMS group relative to the DES group (33.57% vs 15.49%). When compared with the DES group, the BMS group had a significantly higher rate of recurrent symptoms (2.76% vs 11.26%; OR=3.319, p=0.011) and TVR (4.83% vs 19.21%; OR=4.099, p=0.001).ConclusionsA significantly lower rate of restenosis, recurrent symptoms, and TVR was noted in the DES group compared with the BMS group.

✓ A simple technique is described for extracranial vertebral artery vein bypass grafting, utilizing an internal shunt that avoids prohibitively dangerous vertebral artery cross-clamping. This procedure was carred out successfully in a patient with vertebrobasilar insufficiency.

Hunter's Syndrome

Bow hunter's syndrome is an uncommon cause of vertebrobasilar insufficiency resulting from rotational compression of the extracranial vertebral artery. While positional compression of any portion of the extracranial vertebral artery has been reported to result in bow hunter's syndrome, the most common site of compression is the V2 segment as it passes through the foramen transversarium of the subaxial cervical spine. A 43-year-old woman presented with increasingly frequent pre-syncopal and syncopal episodes upon leftward head rotation. Pre-operative angiographic studies with the neck rotated to the left demonstrated occlusion of the left vertebral artery by a C4-5 osteophyte arising from the C4 uncinate process. The patient underwent microsurgical decompression of the vertebral artery at C4-5 through a standard anterior transcervical retropharyngeal approach. Selective vertebral artery intraoperative angiography performed with the head passively rotated to the left before and after left vertebral artery decompression showed marked improvement in the luminal diameter and blood flow. The patient's symptoms resolved post-operatively. This case illustrates the second instance of intraoperative angiography used to confirm adequate vertebral artery decompression for bow hunter's syndrome. Intraoperative angiography can be safely used to decrease the extent of vertebral artery decompression in order to minimize the risk of operative complications.

Abstract Intracranial vertebral endarterectomy was performed on six patients with vertebrobasilar insufficiency in whom medical therapy failed. The patients underwent operations for stenotic plaque in the intracranial vertebral artery with the opposite vertebral artery being occluded, hypoplastic, or severely stenosed. In four of the patients, the stenosis was mainly proximal to the posterior inferior cerebellar artery (PICA). In this group, after endarterectomy, the vertebral artery was patent in two patients, and their symptoms resolved: in one patient the endarterectomy occluded, but the patient's symptoms improved; and in one patient the endarterectomy was unsuccessful, and he continued to have symptoms. In one patient, the plaque was at the origin of the PICA. The operation appeared technically to be successful, but the patient developed a cerebellar infarction and died. In one patient the stenosis was distal to the PICA. During endarterectomy, the plaque was found to invade the posterior wall of the vertebral artery. The vertebral artery was ligated, and the patient developed a Wallenburg syndrome. The results of superficial temporal artery to superior cerebellar artery anastomosis are better than those for intracranial vertebral endarterectomy for patients with symptomatic intracranial vertebral artery stenosis. The use of intracranial vertebral endarterectomy should be limited to patients who have disabling symptoms despite medical therapy, a focal lesion proximal to the PICA, and a patent posterior circulation collateral or bypass.
