Inhaled nitric oxide in acute pulmonary embolism: a systematic review.

Acute pulmonary embolism (PE) is usually a complication secondary to migration of a deep venous clot or thrombi to lungs, but other significant etiologies include air, amniotic fluid, fat, and bone marrow. Regardless of the underlying etiology, little progress has been made in finding an effective pharmacologic intervention for this serious complication. Among the wide spectrum of PE, massive PE is associated with considerable morbidity and mortality, primarily due to severely elevated pulmonary vascular resistance leading to right ventricular failure, hypoxemia, and cardiogenic shock.

Superior mesenteric artery syndrome in a patient with cerebral palsy.

Superior mesenteric artery syndrome involves compression of the third part of the duodenum due to narrowing of the area between the aorta and the superior mesenteric artery (SMA). We will describe the case of a 34-year-old with cerebral palsy who presented with abdominal pain, nausea, vomiting, and weight loss and was diagnosed with SMA syndrome via CT-imaging. With failure of conservative measures, our patient underwent a duodenojejunostomy after which improvement in her weight as well as relief of her abdominal symptoms was noted.
