[Technique of endoscopic subfascial CO2 insufflation-dissection of perforator veins]

Endoscopic subfascial dissection of perforating veins (ESDP) represents a new additional technique for treatment of greater saphenous system varicosities. We present a modification of ESDP, entitled endoscopic subfascial insufflation-dissection of perforating veins (ESIDP). In ESIDP CO2-insufflation induced enlargement of subfascial space (subfascial pneumocave) facilitates identification and dissection of perforating veins. From 1.1.1998 to 1.7.2000, 150 procedures of ESIDP have been conducted in 127 patients (90 females, 37 males). Identification of incompetent perforating and superficial veins and assessment of deep veins were performed preoperatively using duplex sonography. In addition to a description of the surgical technique, we present an overview about indications for ESIDP and possible ESIDP-related postoperative complications.
