Clinical Interpretation of Dynamic Positron Emission Tomography with C-11-methyl-d-glucose Before and After STA-MCA Anastomosis
Neurologic examination, case history, and paraclinical investigations should help in diagnosing and providing the most beneficial therapy for cerebrovascular diseases. Doppler measurements, angiography, serial radionuclide scintigrams, and rCBF measurements are the methods of choice. Positron emission tomography and nuclear magnetic resonance will become future methods for evaluating the extent of a cerebral ischemic event; at present, however, these procedures have only minor importance in clinical practise because of our lack of knowledge about surgically treated stroke patients. Thus it was our goal to sample a series of patients suffering from different grades of cerebral ischemia and undergoing surgery. From the neurosurgical point of view we examined the patients before and after an extra-intracranial arterial bypass (EIAB) operation. Some patients were not operated upon and considered as a medically treated control group. Like the surgically treated group, they were given ASS and, in accordance with Heiss (1983), piracetam (Nootrop).
