title: Autotransplantation of the greater omentum in the treatment of chronic lymphedema.
abstract: We evaluated the use of transplantation of the greater omentum in the management of chronic lymphedema in 21 patients. The omentum provides a large surface with fluid absorbing capability and potentially therefore is useful in management of patients with primary or hypoplastic peripheral lymphatics. Based on the angio- and lymphangio-architecture of the gastroepiploic architecture, we used large segments of greater omentum as a free autotransplant with microrevascularization to the femoral or axillary artery and vein thereby avoiding technical drawbacks of a pedicle graft with the feeding vessels traversing the abdomen. Elongation of the omentum must be done properly because omental lymphatic arcades do not consistently follow the blood vascular arcades in its more distal part. Accordingly, if not properly mobilized the blood supply may be retained whereas the lymph circulation is interrupted. We combined omental implantation with lymph nodal-venous anastomoses using an omental vein with a nearby systemic venous tributary. In 19 of the 21 patients followed from 3 months to 2 years after operation, remission of lymphedema was good (reduction in swelling more than 50%) in 14 patients and satisfactory in 5 (approximately 25-50% reduction in swelling) with improvement gradually increasing with the passage of time.
