BACKGROUND AND PURPOSE In acute ischemic stroke, the hyperdense artery sign (HAS) on noncontrast computed tomography (CT) is thought to represent intraluminal thrombus and, therefore, is a surrogate of arterial obstruction. We sought to assess the accuracy of HAS as a marker of arterial obstruction by thrombus. METHODS The Third International Stroke Trial (IST-3) was a randomized controlled t...

The arterial switch operation (Jatene procedure) is the treatment of choice for transposition of the great arteries with intact ventricular septum (TGA-IVS) in neonatal age, because of the low mortality and morbidity during long term follow up. Right ventricular outflow obstruction is the most frequent postoperative complication, occurring with suYcient severity to require reintervention in up ...

OBJECTIVES The goal of our study was to report our intermediate-term results with aortic root translocation plus arterial switch for d-transposition of the great arteries with left ventricular outflow tract obstruction. BACKGROUND A d-transposition of the great arteries with left ventricular outflow tract obstruction represents a difficult surgical problem. The Rastelli procedure is the usual...

More than any other chronic respiratory disease, asthma is characterized by functional and clinical variability: expiratory flow obstruction, dyspnoea and wheezing may be absent, mild, or severe. Moreover, pulmonary gas exchange often does not closely relate to measured airway obstruction. Accordingly, the correlation between arterial oxygen tension and airflow (Pa,O2) rate indices of obstructi...

 We report a case of Nicolau syndrome in a 15 months old girl following of an intramuscular injection of penicillin 6.3.3 in her left buttock. This case is unique because she developed compartment syndrome in her left calf far from her injection site. Her toe’s tips gangrened in the course of her ailment. We hypothesized that the compartment syndrome might be produced by a probable intra-arteri...

There are enough commonly known causes of backache to torment, as well as to test the skill of, the practising physician. In addition to the more recognised causes. backache from vascular obstruction must be considered. The following observations support this fact. The term claudication properly means limp. and in some instances there may be no pain but only weakness of the legs with disturbanc...

Arterial hypoxemia is a common finding in acute pulmonary embolism, and its severity is generally assumed to be proportional to the extent of pulmonary artery obstruction. We studied blood gases (during room air breathing and 100% oxygen breathing) and hemodynamic data is seven patients with massive pulmonary embolism and circulatory failure. All measurements were made before and 30 minutes aft...

BACKGROUND Disturbed breathing during sleep, with episodic upper airway obstruction, is frequent after major surgery. Ventilatory responses to hypercapnia and hypoxia during episodes of airway obstruction are difficult to investigate because the usual measure, that of ventilation, has been attenuated by the obstruction. We simulated the blood gas stimulus associated with obstruction to allow in...
