Inferior mesenteric arteriovenous fistula with nonpulsatile abdominal mass
RATIONALE Inferior mesenteric arteriovenous fistula (IMAVF) is a rare condition principally characterized by portal hypertension and ischemic bowel disease. Up to now, only 30 cases have been reported. Presented here is an IMAVF patient with nonpulsatile abdominal mass as the main manifestation. PATIENT CONCERNS A 62-year-old Chinese male who complained of abdominal discomfort for a month was...
متن کاملNonpulsatile cerebral perfusion in patient with acute neurological deficits.
BACKGROUND AND PURPOSE An extremely low pulsatile cerebral perfusion can result in a massive cerebral infarction and poor outcome. We report a patient who had complete recovery from initial neurological deficits in spite of nonpulsatile perfusion in the middle cerebral artery. METHODS We used carotid duplex and transcranial Doppler to evaluate cerebral hemodynamics and the National Institutes...
متن کاملPostmortem demonstration of intrapulmonary arteriovenous shunting.
The measurement of the pressure required to drive a 2% solution of gelatin across the pulmonary vascular bed of a group of 49 infants dying suddenly at less than 44 weeks' postnatal age, has shown the presence of low pressure arteriovenous shunting in 30 cases (61%). Injection of polymethylmethacrylate beads in three cases has demonstrated that the vessels that form the shunts are up to 60 micr...
متن کاملClinical comparison of pulsatile and nonpulsatile perfusion during cardiopulmonary bypass.
Controversy exists concerning the utilization of pulsatile flow during cardiopulmonary bypass (CPB) with regard to improved patient outcomes. The purpose of the present study was to evaluate pulsatile perfusion in patients undergoing CPB in a clinical setting. Seventy patients undergoing open heart surgery for repair of valvular or congenital heart disease were prospectively entered into the st...
متن کاملIntramyocardial Blood Volume
We have measured the effects of barium-induced cardiac contraction on the intramyocardial blood volume content of all vessels and have independently measured the blood volume content of vessels with a diameter greater than 100 ,um in rat myocardium. Measurements of total intramyocardial blood volume were made by using [1251]albumin as a plasma marker and technetium-99m as a red blood cell marke...
