Technique of modified inguinal lymphadenectomy.

1. Placement of inguinal incisions
2. Incising to Scarpa's fascia
3. Dissection of the saphenous vein with ligation of its tributaries, and cephalad en bloc dissection of nodal package. Saphenous vein is not divided.
4. View following dissection of the superficial nodes. Fascia lata is intact. Dissection extends from 2- cm superior to the incision inferiorly to 4-cm below the lower edge of the incision.
5. Catalona's modified inguinal lymphadenectomy. Lower dissection ends at the lower limit of the fossa ovalis. Dotted border indicates classical lymphadenectomy limits.
6. Detail of Catalona's dissection, when deep inguinal nodes are included.
