Angiographical extravasation of contrast medium in hemorrhagic infarction. Case report.
Leakage of the contrast medium was noted on angiograms of a patient whose autopsied brain disclosed typical pathological findings of hemorrhagic infarction. The case was a 63-year old woman with mitral valve failure, who suddenly had loss of consciousness and right-sided hemiplegia. The left carotid angiography performed six hours after onset demonstrated middle cerebral arterial axis occlusion...
متن کاملContrast enhancement and contrast extravasation on computed tomography after intra-arterial thrombolysis in patients with acute ischemic stroke.
BACKGROUND AND PURPOSE The goal of this study was to determine the CT findings and clinical consequences of contrast enhancement and contrast extravasation on CT scans obtained after intra-arterial thrombolytic therapy for treatment of acute ischemic stroke. METHODS Sixty-two patients were treated with intra-arterial thrombolysis. All patients underwent nonenhanced CT scans immediately and 24...
متن کاملDelayed high dose contrast CT: identifying patients at risk of massive hemorrhagic infarction.
A prospective clinical study was done on 20 patients referred for computed tomography within 28 hr of a cerebral ischemic event. The patients were scanned before, immediately after, and 3 hr after a high dose of intravenous contrast medium was administered to produce prolonged high blood iodine levels. In seven patients the delayed scan demonstrated a heretofore undescribed type of contrast enh...
متن کاملHemorrhagic cerebral infarction--a prospective study.
In 65 cases of ischemic cerebral infarction, CT scans and quantitative assessments of the neurological disturbances were undertaken at specific intervals during the 4 week period after stroke. Forty-three patients underwent lumbar puncture to determine the serum/CSF albumin ratio. The etiology of the infarction was evaluated on the basis of angiographic, ultrasonic and cardiologic findings. A h...
متن کاملBone marrow-derived cells are the major source of MMP-9 contributing to blood-brain barrier dysfunction and infarct formation after ischemic stroke in mice.
Matrix metalloproteinase (MMP)-9 has been shown to contribute to blood-brain barrier (BBB) disruption, infarct formation, and hemorrhagic transformation after ischemic stroke. The cellular source of MMP-9 detectable in the ischemic brain remains controversial since extracellular molecules in the brain may be derived from blood. We here demonstrate that bone marrow-derived cells are the major so...
