Venous outflow vessels important in microvascular breast reconstruction.
2003 OCT 2 - (NewsRx.com & NewsRx.net) -- Alternative venous outflow vessels can be important in microvascular breast reconstruction.
"The lack of adequate recipient vessels often complicates microvascular breast reconstruction in patients who have previously undergone mastectomy and irradiation. In addition, significant size mismatch, particularly in the outflow veins, is an. important contributor to vessel thrombosis and flap failure," scientists writing in the journal Plastic and Reconstructive Surgery report.
"The purpose of this study was to review the authors' experience with alternative venous outflow vessels for microvascular breast reconstruction. In a retrospective analysis of 1278 microvascular breast reconstructions performed over a 10-year period, the authors identified all patients in whom the external jugular or cephalic veins were used as the outflow vessels," wrote B.J. Mehrara and colleagues, Memorial Sloan-Kettering Cancer Center.
"Patient demographics, flap choice, the reasons for the use of alternative venous drainage vessels, and the incidence of microsurgical complications were analyzed," the researchers stated.
"The external jugular was used in 23 flaps performed in procedures with 22 patients. The superior gluteal and transverse rectus abdominis musculocutaneous (TRAM) flaps were used in the majority of the cases in which the external jugular vein was used (72% gluteal, 20% TRAM flap). The need for alternative venous outflow vessels was usually due to a significant vessel size mismatch between the superior gluteal and internal mammary veins (74%)," the researchers wrote.
"For three of the external jugular vein flaps (13%), the vein was used for salvage after the primary draining vein thrombosed, and two of three flaps in these cases were eventually salvaged. In three patients, the external jugular vein thrombosed, resulting in two flap losses, while the third was salvaged using the cephalic vein," the researchers ...
