Recent supermicrosurgical techniques have developed the possibility for vascular anastomosis of smaller vessels and it is now safe and sound to perform precise anastomoses between lymphatics and venules. Reported here is the 2 years experience on supermicrosurgical lymphaticovenular anastomosis and/or lymphaticovenous implantation combined with a nonoperative physical therapy for treatment of lower extremity lymphedema. Microlymphatic surgery was performed in 42 patients with unilateral lower extremity lymphedema. Thirty patients were women and 12 were men with a mean age of 34. Lymphaticovenular anastomoses were performed in 37 patients with an average of 2.5 anastomoses per patient, and lymphaticovenous implantations were made in 36 patients with an average of 2.4 implantations per patient. The lymphatics that were larger than 0.3 mm were anastomosed to venules with supermicrosurgical technique. Lymphaticovenous implantation technique was used for thinner lymphatics in a particular incision. Postoperatively, 18 patients used continuous compressive garments, 9 patients used garments but discontinued after 6 months, and no compression was used in 9 patients. The results of surgery were assessed both clinically with volume measurements and by lymphoscintigraphy and were classified as good, moderate, or ineffective. The mean decrease in the volume of the edema was 59.3% at an average follow-up of 11.8 months. Six outcomes were classified as ineffective, eight outcomes as moderate, and 28 outcomes as good. Supermicrosurgical lymphaticovenular anastomosis and/or lymphaticovenous implantation seems to be highly beneficial, especially in the early stages of peripheral lymphedema and may be offered as the treatment of choice in selected patients.
Although some authors previously stated that microlymphatic surgery does not have application to primary lymphedema, opposite views are reported based on the observations that the lymphatics were not hypoplastic in majority of these patients and microlymphatic surgery yielded significant improvement. The aim of this study was to compare the intraoperative findings and outcomes of primary and secondary lower-extremity lymphedema cases treated with lymphaticovenous shunts. Between December 2006 and April 2009, microlymphatic surgery was performed in 80 lower extremities with primary and 21 with secondary lymphedema. These two groups of extremities are compared according to the morphology of the lymphatic vessels and possibility of precise anastomoses, their response to the treatment, and final outcomes based on volumetric measurements during the follow-up period. The morphology of the lymphatics in secondary lymphedema was more consistent, and at least one collector larger than 0.3 mm was available for anastomosis in 20 of 21 extremities. In the primary lymphedema group, the lymphatics were smaller than 0.3 mm in 13 of 80 extremities. It was, therefore, possible to perform supermicrosurgical lymphaticovenous anastomosis in 84% of extremities with primary lymphedema and 95% of extremities with secondary lymphedema. Reduction of the edema occurred earlier in the secondary lymphedema group, but the mean reduction in the edema volume was comparable between the two groups. Microlymphatic surgery, although more effective and offered as the treatment of choice for secondary lymphedema, would also be a valuable and relevant treatment of primary lymphedema.
Described in this study is a surgical concept that supports the "consider and use a pedicled perforator flap whenever possible and indicated" approach to reconstruct a particular skin defect. The operation is entirely free-style; the only principle is to obtain a pedicled perforator flap to reconstruct the defect. The perforators are marked with a hand-held Doppler probe and multiple flaps are designed. The appropriate flap is elevated after identifying the perforator(s). Dissection of the perforator(s) or complete incision of the flap margins are not mandatory if the flap is mobilized adequately to cover the defect. Defects measuring 3 x 3 cm up to 20 x 20 cm at diverse locations were successfully reconstructed in 20 of 21 patients with 26 flaps. Pedicled perforator flaps offer us reliable and satisfactory results of reconstruction at different anatomic territories of the body. It sounds more practical and creative to use a free-style manner during pedicled perforator flap surgery, instead of being obliged to predefined templates for this type of procedure.
This is a report on a novel technique of neoglans reconstruction in a patient with an amputated glans penis as a result of a gunshot injury. A pedicled deep inferior epigastric artery perforator (DIEAP) flap measuring 7 x 4 cm and centralizing the uppermost perforators in the right abdominal region was used. The distal penile skin was used to elongate the urethra. A subcutaneous tunnel was created alongside the penis and underneath the mons pubis. The flap was passed through this tunnel, fashioned into the shape of a glans, and secured in place around the neourethra. The patient had a satisfactory neoglans and a functional urethra at 4-month follow-up. The pedicled DIEAP flap is a suitable option for reconstruction of the glans penis.
