Patients with dural arteriovenous fistulas (DAVFs) in the transverse-sigmoid sinus suffer from several symptoms: bruit, headache, visual impairment, and so on. But depression is rare in patients with DAVF. The authors reported a rare case presenting the improvement of depression after the treatment of a dural arteriovenous fistula in the left transverse-sigmoid sinus. A 46-year-old male had suffered from depression and was treated with antidepressants at a local hospital for four years. The patient was temporarily laid off due to his depression. Afterwards, he had Gerstmann's syndrome and came to our hospital. A DAVF in the left transverse-sigmoid sinus was demonstrated on the angiogram. The DAVF was successfully treated with endovascular surgery, coil embolization of the isolated diseased sinus through the mastoid emissary vein which was a draining vein from the fistula. After this treatment, his depression as well as Gerstmann's syndrome was improved and the quantity of the antidepressants decreased. The patient returned to work without any antidepressant two years after the treatment. DAVFs might be one of the causes of depression. It may be necessary to evaluate cerebral vessels in patients suffering from depression by using MRA or 3D-CTA even if there are not any abnormal findings on plain CT scans.

Introduction: Percutaneous transvenous embolization (TVE) using coils is a well-established treatment of cavernous sinus dural arteriovenous fistula (CSdAVF). However, it is sometimes difficult to achieve complete occlusion by coil embolization. In these two cases, we were able to obtain complete angiographic obliteration of the fistulas without complications by means of percutaneous TVE using n-butyl-cyanoacrylate (NBCA) after we failed when TVE using coils. Case 1: An 89-year-old woman presented with double vision. She was diagnosed as Barrow type D right CSdAVF draining only to the cortical vein. We treated the patient by TVE using coils, but the microcatheter was withdrawn before complete occlusion was attained. The repositioning of the microcatheter was difficult, so we used 30% NBCA for TVE, and obtained complete obliteration of the fistula. Case 2: An 87-year-old woman presented with right exophthalmos, and chemosis. She was diagnosed as Barrow type C right CSdAVF draining only to the right superior ophthalmic vein with very slow flow. We planned to treat her, using TVE with coils, but we could place only 3 coils and obtained only partial obliteration of the fistula. So we additionally used 25% NBCA for TVE, and obtained complete obliteration of the fistula. Conclusion: Compared to TVE using coils, TVE using NBCA gives rise to many problems, but, we can use NBCA as a second option if TVE using coils results in only partial obliteration as in these cases.

BACKGROUND: There are significant differences in the postoperative morphological and hemodynamic conditions of the carotid arteries between carotid artery stenting (CAS) and endarterectomy (CEA). OBJECTIVE: To compare the postoperative rheological conditions after CAS with those after CEA with patch angioplasty (patch CEA) through the use of computational fluid dynamics (CFD) based on patient-specific data. METHODS: The rheological conditions in the carotid arteries were simulated in 2 patients after CAS and in 2 patients after patch CEA by CFD calculations. Three-dimensional reconstruction of the carotid arteries was performed with the images obtained with computed tomography angiography. The streamlines and wall shear stress (WSS) were calculated by a supercomputer. Adequate boundary conditions were determined by comparing the simulation results with ultrasound flow data. RESULTS: CFD was successfully calculated for all patients. The differences between the flow velocities of ultrasound data and those of the simulation results were limited. In the streamline analysis, the maximum flow velocities in the internal carotid artery after patch CEA were around two-thirds of those after CAS. Rotational slow flow was observed in the internal carotid artery bulb after patch CEA. WSS analysis found regional low WSS near the outer wall of the bulb. High WSS was observed at the distal end of the arteriotomy after patch CEA and at the residual stenosis after CAS. CONCLUSION: CFD of postoperative carotid arteries disclosed the differences in streamlines and WSS between CAS and patch CEA. CFD may allow us to obtain adequate rheological conditions conducive to achieving the best clinical results.

脳血管攣縮 26 34 - 37 2011.2

Language：Japanese Publisher：スパズム・シンポジウム事務局

過去5年間にくも膜下出血発症48時間以内にクリッピングまたはコイル塞栓術を施行し、術後シルビウス裂末梢部に血腫が残存した92例のうち、World Federation Neurological Surgery(WFNS) grade 1〜3で、脳血管攣縮(VS)治療プロトコールに沿った治療においても治療困難であった5症例について検討した。その結果、2例はINVOSによるVS検知が不十分で、局所の攣縮や末梢性の攣縮を来たした。2例は循環器、呼吸器合併例で、VSの治療とは相反する脱水の是正、昇圧等を優先しなければならず、脳梗塞を引き起こしていた。1例は腹壁出血例であった。脳槽ドレーン脱落等によって、早期にくも膜下血腫線溶治療が行えず、結果としてVSを来した症例も散見された。
