Abstract:
A 46-year-old man with a medical history notable only for schizophrenia was admitted to hospital with complaints of general fatigue and high fever. Transthoracic echocardiography on day 6 after admission demonstrated a large vegetation (17 mm) on the anterior leaflet of the mitral valve with mild regurgitation and mild aortic regurgitation. The patient also complained of abdominal pain. Abdominal computed tomography showed a remarkable enlargement of the superior mesenteric artery aneurysm (SMAA). An excision of the SMAA and double valve replacement was performed, and the patient was administered a six-week course of intravenous antibiotic therapy.

Veins of the Abdomen and Pelvis
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...
Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
