Document Summary

Riu 436 vascular procedures for general ultrasound i. 1. the image below represents tcd findings from a 6-year-old male who underwent abdominal surgery for perforated bowel, which was complicated by recurrent episodes of ventricular fibrillation and cardiac arrest, requiring cardiopulmonary resuscitation. This tcd was performed on day 4 due to absent pupilary reflex and poor gag reflex. Alternating flow spectra were obtained from the right middle cerebral artery (mca) and basilar artery while left mca demonstrated only systolic spikes. What is this finding indicative of: sickle cell disease, vasospasm, intracranial occlusion, brain death. 2. a 61-year-old male with a history of smoking and hypertension was found lying on the floor with right facial droop, right sided paralysis, and aphasia. He had a large hematoma on the left forehead. A head ct showed a left basal ganglia and subinsular region infarct. A cta showed occlusion of his left ica. A tcd was done to evaluate for collateral flow.
