Bow hunter's syndrome refers to symptomatic vertebrobasilar insufficiency provoked by physiologic head rotation. ⋯ This case describes the first use of intraoperative Doppler ultrasonography directly upon the vertebral artery to provide an unrestricted real-time assessment of the surgical decompression for bow hunter's syndrome.

Treatment strategy for giant aneurysms in the cavernous portion of the internal carotid artery.
As direct surgery to treat giant aneurysms of the ICA is difficult, ICA occlusion is the conventional treatment in patients with BTO tolerance. To determine whether bypass surgery should be performed after carotid occlusion by trapping or proximal occlusion, we developed a treatment strategy that includes BTO and SPECT. ⋯ Based on our experience, we recommend that patients with giant aneurysms in the cavernous portion of the ICA be evaluated by BTO and SPECT. In conjunction with bypass surgery, ICA trapping or proximal occlusion constitutes an effective treatment strategy.

We report on a 68-year-old woman with an abnormal loop of the extracranial VA enlarging the intervertebral foramen at C4-5 and compressing the C5 root causing radiculopathy. The diagnosis was confirmed on contrast enhanced CT and MR angiography after initial conservative treatment was unsuccessful. Microvascular decompression using an anterior approach was curative.

The protective effect against ischemic stroke by systemic hypothermia is limited by the cooling rate and it has severe complications. This study was designed to evaluate the effect of SBH induced by epidural cooling on infarction volume in a swine model of PMCAO. ⋯ The present study has demonstrated, with histologic confirmation, that epidural cooling may be a useful strategy for reducing infarct volume after the onset of ischemia.
