conclusions it seems that there is no difference in the use of heparinized and normal saline solutions to prevent catheter occlusion of arterial and central venous pressure. patients and methods in the current randomized controlled trial, 100 patients, with an age range of 18 - 65 years of valve and coronary artery surgery were studied in rajaie heart center, tehran, iran. patients were randomi...

OBJECTIVE To assess whether the x-ray attenuation of intra-arterial obstruction measured on non-contrast CT in ischemic stroke can predict response to thrombolysis and subsequent functional outcome. METHODS The Third International Stroke Trial (IST-3) was a multicenter randomized-controlled trial of intravenous thrombolysis (rt-PA) given within six hours of ischemic stroke. Ethical approval a...

Arteritis due to Strongylus vulgaris is a well-known cause of colic in horses and donkeys. The current report describes a fatal incidence of arterial obstruction in cranial mesenteric artery caused by S. vulgaris infection in an adult donkey in which anthelmintic treatment was not regularly administered. Necropsy findings of the abdominal cavity revealed a complete cranial mesenteric arterial o...

PURPOSE In this study, the pulmonary arterial computed tomography obstruction index ratio, which indicates the degree and extent of thrombotic arterial occlusion, was calculated in cases with pulmonary thromboembolism. Our objectives were to investigate the value of this index for the identification of cases with massive pulmonary thromboembolism and to search for correlations between this inde...

We present a 69-year-old woman with a duodenal obstruction after successful selective transcatheter arterial embolization (TAE) for a duodenal diverticular hemorrhage. Two weeks after TAE, the patient showed abrupt symptoms of duodenal obstruction. Resolving hematomas after successful selective transcatheter arterial embolization should be thoroughly observed because they might result in duoden...

1. In 12 unselected outpatients with chronic obstructive pulmonary disease and six controls, arterial pH, PaO2, PaCO2 and oxygen saturation (SaO2), forced expiratory volume in 1.0 s (FEV1.0) and vital capacity were measured. Subjects were grouped into those with or without obstruction based on the Tiffenau index. The Baseline Dyspnoea Index was employed to objectify the severity of dyspnoea and...

Cardiac output and arterial blood gases were studied before, during, and after intermittent positive pressure breathing, using 40% oxygen (IPPB i02). The subjects of this study were eight patients with lung disease, seven of them with chronic airflow obstruction and eight control subjects without respiratory symptoms. During IPPB/02, cardiac output was definitely lowered without a significant d...

Retrograde arterial catheterization in children and young adults carries a risk of vessel damage and occlusion. The management of 29 such injuries is presented. The first patient in this series died after amputation of his lower extremity for gangrene. In all patients in whom distal pulses were absent 8 hours after catheterization arterial obstruction was complete. Claudication developed in the...
