Overview
abstract
Before 1985, surgery on incompetent perforator veins in patients with severe, chronic, venous insufficiency and venous ulcerations was generally performed utilizing long skin incisions through diseased skin and subcutaneous tissues. Known as "the Linton operation," wound infections and poor healing complicated this procedure. In 1985 G. Hauer demonstrated a new surgical technique for identifying and ligating incompetent perforator veins using an endoscopic approach in the limbs' subfascial space. This seminal contribution marked the advent of subfascial endoscopic perforator surgery (SEPS). From 1996 to 2003 our group prospectively collected data on 86 patients with chronic venous insufficiency (CVI) who underwent a SEPS procedure. Preoperative assessment consisted of color-flow duplex ultrasound scanning and ascending and descending phlebography. The patient's ages ranged from 42 to 82 years (mean 60). A total of 98 limbs underwent the SEPS procedure from the cohort group of 86 patients. The CHEAP classification of the limb disease was used: 45 limbs were classified as group C5, 53 limbs group C6. Ninety-eight SEPS procedures were performed without significant morbidity on 86 patients. Of the 53 limbs in class C6, 41 had ulcer healing within 12 weeks. The remaining 12 limbs in class C6 had ulcer healing within 6 months. In this latter group, 9 had ulcers greater than 4 cm in widest diameter. These patients underwent a split-thickness skin graft at the time the SEPS procedure was performed. The grafts have remained intact after 2 years in this cohort group. The results of this study demonstrate that the SEPS procedure incorporated into the overall treatment plan for patients with CVI produces excellent healing with minimal postoperative complications. The study also underscores the important role incompetent perforator veins have in the formation of venous ulcers.
