Peritoneovenous Shunt
An operation for the continuous emptying of ascitic fluid into the venous system. Fluid removal is based on intraperitoneal and intrathoracic superior vena cava pressure differentials and is performed via a pressure-sensitive one-way valve connected to a tube traversing the subcutaneous tissue of the chest wall to the neck where it enters the internal jugular vein and terminates in the superior vena cava. It is used in the treatment of intractable ascites.
Parenteral Nutrition, Total
The delivery of nutrients for assimilation and utilization by a patient whose sole source of nutrients is via solutions administered intravenously, subcutaneously, or by some other non-alimentary route. The basic components of TPN solutions are protein hydrolysates or free amino acid mixtures, monosaccharides, and electrolytes. Components are selected for their ability to reverse catabolism, promote anabolism, and build structural proteins.
Pericardiectomy
Lymphangiomyoma
A tumorlike condition characterized by SMOOTH MUSCLE and ENDOTHELIUM proliferation of LYMPHATIC VESSELS and LYMPH NODES in the MEDIASTINUM and retroperitoneum, also in the lung. It may be manifested by chylous PLEURAL EFFUSION and ASCITES.
Lymphangiectasis, Intestinal
Jejunostomy
Pericarditis, Constrictive
Inflammation of the PERICARDIUM that is characterized by the fibrous scarring and adhesion of both serous layers, the VISCERAL PERICARDIUM and the PARIETAL PERICARDIUM leading to the loss of pericardial cavity. The thickened pericardium severely restricts cardiac filling. Clinical signs include FATIGUE, muscle wasting, and WEIGHT LOSS.
