n't proved effective," said lead author on the study David W. Chang, M.D., professor in the Department of Plastic Surgery and Director of the Plastic Surgery Clinic at M. D. Anderson. "Surgical techniques, in particular, have been limited and therefore have been met with skepticism by surgeons, making it extremely important to determine which new techniques promise to bring real benefits to patients."

In lymphaticovenular bypass surgery, surgeons use tiny microsurgical tools to make two to three small incisions measuring an inch or less in the patient's arm. Lymphatic fluid is then redirected to microscopic vessels - approximately 0.3 - 0.8 millimeters in diameter - to promote drainage and alleviate lymphedema. The procedure is minimally invasive and is generally completed in less than four hours under general anesthesia, allowing patients to return home from the hospital within 24 hours. M. D. Anderson is among a few institutions in the United States to offer this technically complex surgery.

"Lymphedema is like a massive traffic jam with no exit," Chang said. "This procedure does a lot to help relieve lymphedema by giving the fluid a way out. While it does not totally eliminate the condition, there is very little downside for the patient and we may see significant improvement in its severity."

Chang notes that while most effective when completed in earlier stages before the affected arm is fibrotic, almost any breast cancer patient suffering from lymphedema stage I, II or III is a candidate. Though breast cancer was the focus of this study, the surgery can also be performed on patients who have lymphedema in the leg resulting from cancers involving pelvic regions.

Cancer treatment is not the only cause of lymphedema. Primary lymphedema can develop from developmental causes at birth, the onset of puberty or in adulthood. Secondary lymphedema can develop as a result of surgery, radiation, infection or trauma. In developing cou
