The carotid angiograms of 96 patients who had died from non-missile head injury were reviewed and assessed for evidence of arterial spasm, slowing of the cerebral circulation, and the presence of intracranial haemotoma. As bilateral angiography had been done in 44 cases the results are based on a correlation between the angiographic appearances and the presence or absence of ischaemic brain dam...

A Model for Experimental Cerebral A rterial Spasm • Vasospasm of the basilar artery of the dog was induced by subarachnoid injection of arterial blood through the cisterna magna. Cerebral angiography was employed to evaluate quantitative assessment of the spasm. Chronic vasospasm was successfully induced in 100% of surviving dogs. Biphasic vasoconstriction was observed. The acute phase occurred...

Coronary artery vasospasm following administration of sublingual (SL) nitroglycerin (NTG) was first described in the literature by Feldman and colleagues in 1978 [1]. The frequency of this finding and its clinical significance is unknown; however, it is corroborated by other reports of paradoxical blood pressure elevation after nitroglycerin administration [2] and anecdotally noted rare patient...

Background. It has been suggested that recurring coronary artery spasm may lead to the development of fixed atherosclerotic coronary obstructions. Methods and Results. We studied 10 patients with typical Prinzmetal's variant angina in whom the disease remained active for years and in whom occlusive coronary spasm occurred reproducibly at the same arterial site during repeat coronary arteriograp...

BACKGROUND Coronary artery spasm (CAS) is defined as a reversible, sudden epicardial coronary artery stenosis that causes vessel occlusion or near occlusion. CASE REPORT In this article, we present a clinical case of CAS in a 48-year-old woman undergoing elective aortic valve replacement surgery for aortic stenosis. On the 3rd post-operative day, the patient suffered from chest pain and dyspn...

Three patients had hypertrophic obstructive cardiomyopathy and coronary artery spasm. The clinical diagnosis of hypertrophic obstructive cardiomyopathy, in all patients, was confirmed by echocardiography and angiography. Significant spasm of the right coronary artery was demonstrated in each patient by selective coronary arteriography. One patient had atherosclerotic obstructive three vessel di...

Coronary arteriography was performed before and after the intracoronary injection of nitroglycerin to determine the presence or absence of spasm in patients within the first 12 hours of acute myocardial infarction. Coronary arterial spasm was demonstrated in six of fifteen (40%) acute myocardial infarctions associated with coronary artery disease. In five of the six instances the interval from ...

We report a 67-year-old Japanese man who presented with worsening heart failure with asymptomatically transient ischemic ST-segment depression. Left ventriculography showed diffuse hypokinesis; asymptomatic coronary artery spasm was evoked by the acetylcholine provocation test. Endomyocardial biopsy exhibited hypertrophic cardiomyocytes and scattered microscopic focal myocardial necrosis with a...

Nine cases of hemifacial spasm have been treated by posterior fossa exploration without mortality or significant morbidity. In only three was definite pathology found, but the hemifacial spasm was abolished in eight patients and markedly diminished in the remaining patient. The condition has reccurred in one patient. Microsurgical techniques make the operation safe and accurate. We suggest that...
