Use of an intercostal vein for central venous access in home parenteral nutrition: a case report.

A key factor in the success of a home parenteral nutrition program is prolonged and safe access to the central venous system. There are some patients, however, in whom the cephalic, external jugular, internal jugular, subclavian, and saphenous veins cannot be used. In these patients, cannulation of an intercostal vein can be useful for central venous access. Such a patient was recently presented to our medical care facility with bilateral subclavian vein thrombosis, left external iliac vein thrombosis, and superior vena cava obstruction above the level of the azygous vein. A Broviac catheter was successfully introduced via a right intercostal vein cutdown with the catheter tip lying in the azygous arch. This is the first known description in an adult patient in the use of an intercostal vein to gain access into the central venous system.
