Computerized Angiographic Occlusion Rating for Ruptured Clipped Aneurysms is Superior to Subjective Occlusion Rating.
BACKGROUND AND PURPOSE The computerized occlusion rating to estimate angiographic occlusion of embolized aneurysms is superior to the subjective occlusion rating. In this study, we compared the 2 methods in the analysis of aneurysms clipped after subarachnoid hemorrhage. MATERIALS AND METHODS The pre- and postoperative angiographic images (DSA) of 95 selected patients were analyzed and strati...
متن کاملComputerized occlusion rating: a superior predictor of aneurysm rebleeding for ruptured embolized aneurysms.
BACKGROUND AND PURPOSE The initial angiographic occlusion rate is the strongest predictor of later rebleeding in previously ruptured coil-embolized cerebral aneurysms. Angiographic estimations of aneurysmal occlusion rates are, however, subjective in nature and confounded by methodologic problems. COR has been developed, and its superiority has been experimentally established to overcome subjec...
متن کامل3D computerized occlusion rating of embolized experimental aneurysms using noninvasive 1.5T MR imaging.
BACKGROUND AND PURPOSE For embolized cerebral aneurysms, the initial occlusion rate is the most powerful parameter to predict aneurysm rerupture and recanalization. However, the occlusion rate is only estimated subjectively in clinical routine. To minimize subjective bias, computer occlusion-rating (COR) was successfully validated for 2D images. To minimize the remaining inaccuracy of 2D-COR, C...
متن کاملComputerized assessment of angiographic occlusion rate and coil density in embolized human cerebral aneurysms.
BACKGROUND AND PURPOSE Computerized methods have been introduced for more objective quantification of angiographic occlusion rate and coil density as parameters of successful embolization. This study aimed 1) to evaluate this new computerized method for angiographic occlusion rating and coil density calculations by comparison with corresponding histometric parameters from retrieved human aneury...
متن کاملLate adverse events in coiled ruptured aneurysms with incomplete occlusion at 6-month angiographic follow-up.
BACKGROUND AND PURPOSE Patients with coiled ruptured aneurysms with incomplete occlusion at 6 months are not only at risk for rebleed during further follow-up but also for complications of angiographic follow-up and retreatment, and for progressive mass effect by uncontrollable aneurysm growth. We assessed the frequency and outcome of all these possible aneurysm-related events in 124 patients w...
