The authors reported a case of a dural arteriovenous fistula (DAVF) in the left transverse-sigmoid sinus, in which 3-dimensional computed tomography (CT) angiograms (3D-CTAs) by a 64-section multidetector row CT scanner were useful for its diagnosis and treatment. The DAVF in the left transverse-sigmoid sinus appeared on the digital subtraction angiogram. 3D-CTAs were obtained by a 64-section multidetector row CT scanner before an endovascular treatment. The feeders and draining veins of the DAVF were clearly demonstrated on the 3D-CTAs, which clarified the relationship between the normal dural sinuses and DAVF. The DAVF was successfully treated with endovascular surgery, a transvenous embolization through the mastoid emissary vein, which was easily detected by using the 3D-CTA, showing both the subcutaneous vein and calvalium. 3D-CTAs by a 64-section multidetector row CT scanner are useful for both diagnosis and treatment of DAVFs.

Images of dural arteriovenous fistula (DAVF) on computed tomography (CT) are usually normal when 110 hemorrhages have occurred from the DAVF. Therefore, it is difficult to diagnose DAVF by plain CT scans which are usually performed in an initial examination. We present a rare case with DAVF in the transverse-sigmoid sinus that Could be diagnosed by reversible speckled high-density spots on a plain CT scan. A 46-year-old man had suffered from depression and had taken some antidepressants for 4 years. He developed a Gerstmann's syndrome and came to our hospital. On a plain CT scan obtained on admission, multiple high-density spots were demonstrated scattered in the left temporal, parietal, and occipital lobes. Subsequently, a digital Subtraction angiography was performed. A DAVF in the left transverse-sigmoid sinus was apparent on the angiogram. The DAVF was successfully treated with endovascular Surgery. The speckled high density decreased on the postoperative plain CT scan. Multiple high-density abnormalities in the brain shown on a plain CT scan are a rare but important finding for diagnosis of DAVF. Further examinations such as magnetic resonance angiography or digital subtraction angiography should be performed in case with these changes to access the possibility of DAVF.

Many studies have shown that a motif of 11 consecutive arginines (11R) is one of the most effective protein transduction domains (PTD) for introducing proteins into the cell membrane. By conjugating this "11R", all sorts of proteins can effectively and harmlessly be transferred into any kind of cell. We therefore examined the transduction efficiency of 11R in cerebral arteries and obtained results showing that 11R fused enhanced green fluorescent protein (11R-EGFP) immediately and effectively penetrated all layers of the rat basilar artery (BA), especially the tunica media. This method provides a revolutionary approach to cerebral arteries and ours is the first study to demonstrate the successful transduction of a PTD fused protein into the cerebral arteries. In this review, we present an outline of our studies and other key studies related to cerebral vasospasm and 11R, problems to be overcome, and predictions regarding future use of the 11R protein transduction method for cerebral vasospasm (CV).

Rebleeding from a vertebral artery dissecting aneurysm after endovascular internal trapping: Adverse effect of intrathecal urokinase injection or incomplete occlusion? - Case report

A 67-year-old woman suffered rebleeding from a ruptured vertebral artery dissecting aneurysm after endovascular internal trapping. The dissecting aneurysm was initially successfully occluded with the affected vertebral artery using detachable coils. However, rebleeding from the aneurysm occurred on the next day. The rebleeding may have resulted from the thrombolytic effect of urokinase, which was injected intrathecally 3 hours before rebleeding occurred, or the relatively loose coil packing of the aneurysm. This case indicates the potential risk of intrathecal use of thrombolytic agents and the importance of complete tight coil packing of the whole dissected site in the treatment of ruptured vertebral artery dissecting aneurysms.

Introduction: Bow hunter's syndrome is a unique clinical entity caused by mechanical occlusion of the vertebral artery on head rotation. Although it is usually treated by direct surgical intervention, we report successful treatment using endovascular stent placement for contralateral vertebral artery stenosis. Case Description: A 56-year-old man presented with repeated vertigo and loss of consciousness caused by turning his head to the left. Right vertebral angiogram showed no abnormalities with the head in the neutral position. However, with the head rotated 60 to the left, the right vertebral artery was completely occluded at the C1-2 level. A three-dimensional angiogram with bone window clearly demonstrated vertebral artery compression at the C1-2 level by the bony structure. The left subclavian angiogram revealed severe stenosis at the origin of the left vertebral artery. Left vertebral artery angioplasty followed by stent placement was successfully performed under local anesthesia. The patient showed an uneventful postoperative course and his preoperative symptoms disappeared. At 6 months postoperatively, a left subclavian angiogram showed good patency of the stented left vertebral artery and the patient showed no recurrent symptoms. Conclusion: Vertebral artery stenting is a useful and less invasive option in the treatment of bow hunter's syndrome in the setting of contralateral vertebral artery stenosis. © Georg Thieme Verlag KG Stuttgart.

脳血管に対する外来蛋白質導入法としての「蛋白質セラピー法」の可能性を模索するため、11Rにマーカー蛋白質である緑色蛍光色素タンパク(EGFP)を融合させて(11R-EGFP)、脳血管に対する導入効率を検討した。ラット大槽内に11R-EGFP、EGFPまたは生理食塩水を注入し、注入2、6時間後に脳底動脈を取り出し凍結切片を作成し、蛍光顕微鏡で観察した。その結果、注入2、6時間後に11R-EGFPタンパク質は、脳底動脈壁へ著明に導入されていた。一方、11Rを付加していないEGFPは、くも膜下腔にその存在を認めたが、脳底動脈壁には導入を認めなかった。部位別に導入効果率を検討するため、Scionイメージで蛍光強度の測定を行ったところ、11R-EGFP群は、EGFPおよび生理食塩水注入群と比較して、特に中膜に高い蛍光強度を示した。蛋白質セラピーのこれらの特徴は、くも膜下出血後の脳血管攣縮や脳梗塞等の急性で一過性の脳血管障害の治療に適していると考えられた。
