A comparison of conservative therapy and early selective ligation in the treatment of lymphatic complications following vascular procedures

Background: Lymphatic leakage is a relatively uncommon but serious complication following vascular procedures. A conservative approach consisting of bed rest, leg elevation, prophylactic antibiotics, compressive dressings, and intermittent aspiration is the most commonly used treatment. Because of the long time it takes to cure this condition and the potential for infections, a more aggressive approach consisting of wound exploration and ligation of the leaking lymphatic has been proposed. We review our experience of the past 3 years treating 17 of these complications by using 1 of these 2 approaches. Patients and methods: Seventeen groin complications were seen over a period of 3 years. Ten (59%) patients were treated by selective ligation assisted with isosulfan blue dye injection, and the remaining 7 (41%) were treated conservatively. Results: Mean hospital stay was 2.4 days (range 1 to 4) for the operative group versus 19 days (range 14 to 42) for the conservative group. One complication was seen in the operative group, whereas 4 (57%) patients developed groin infections following conservative therapy. One (10%) patient developed a recurrence following ligation that was treated successfully by reoperation. Conclusion: Our experience with the use of surgical ligation of leaking lymphatic assisted by isosulfan blue, when compared with conservative treatment, has led to a decrease in hospital stay, lower complication rates, and fewer recurrences. In our view, this approach represents the best form of treatment for postoperative groin lymphatic complications.
