PY - 2011 T2 - Venous and Lymphatic Diseases AB - Among the numerous causes of abdominal pain, vascular causes comprise an extremely important group that requires prompt recognition and detection. Although some of these abdominal events may be acute, others often present as a chronic debilitating disorder. Compromise of blood flow to and from the gastrointestinal tract may result in ischemia of varying degrees. Although most events are arterial in nature, 5% to 15% of cases involve the mesenteric venous structures. This vascular source of abdominal pathology often goes unrecognized and has a wide gamut of presentations. Most involve the superior mesenteric vein (SMV), but other processes involve the portal vein, splenic vein, hepatic vein, or inferior mesenteric vein (IMV). This chapter discusses the anatomy, etiology, pathophysiology, clinical presentation, diagnosis, and management of splanchnic venous disease. Furthermore, arteriovenous malformations (AVMS) of the gastrointestinal tract and certain rare vascular disorders are examined as related entities to splanchnic venous disease.
