AIMS Many investigators have speculated that hyperintense plaques (HIPs) of the carotid artery on non-contrast T1-weighted imaging (T1WI) in magnetic resonance indicate the presence of mural or intraplaque haemorrhage containing methemoglobin. Coronary plaque imaging with T1WI is challenging, and the clinical significance of coronary HIP on T1WI remains(More)
SUMMARY Contralateral carotid artery occlusion is thought to represent a significant risk factor in carotid endarterectomy (CEA). There is also evidence that intraoperative and postoperative hypotention may cause contralateral hemodynamic ischemia. As such, contralateral carotid artery occlusion is regarded as a risk factor for carotid angioplasty and(More)
SUMMARY To examine the long term results of endovascular treatment of cerebral aneurysms with the Guglielmi detachable coil (GDC) system, follow- up (F/U) angiography was performed at 6, 12 and 24 months after the procedure. We analyzed 45 cases, 49 procedures of GDC treated cerebral aneurysms from 1997.6. to 2000.5. Follow- up angiography was achieved at(More)
SUMMARY We summarize our clinical experience of the local fibrinolysis for the middle cerebral artery (MCA) embolism.We added residual CBF factors of the ischemic territories to the usual criteria for the indication of fibrinolysis by Xe-SPECT CBF measurement. Forty-nine cases of local fibrinolysis for MCA embolism were reviewed and the results were(More)
SUMMARY We summarized our clinical experience of thrombolytic therapy for cerebral embolism to evaluate the relation between the prognosis and the occlusion site, and the role of pre-treatment CBF measurement for supratentorial cerebral embolism. 56 cases of thrombolysis were analyzed and results were compaired with conservative medical therapy group.
