Minimally invasive treatment for Klippel-Trenaunay syndrome / 中国微创外科杂志

ABSTRACT

Objective To summarize the clinical experience of minimally invasive treatment (sclerosing therapy, intravascular intervention, laser coagulation, etc) for Klippel-Trenaunay syndrome (K-TS). Methods A total of 32 patients with K-TS were treated in this hospital from February 1989 to November 2004. Vascular embolization was used in patients with abnormal arteriovenous fistula or abnormal collateral arterial pathway. The insufficient valves of the deep veins were minimally invasively repaired. Laser coagulation was utilized for treating bulky varicosities. For angiomas and engorged venous plexus of the limbs, the sclerosing agent was injected. Results Varicosis, including reticular venous dilation, subsided completely. Angiography revealed an immediate disappearance of arteriovenous fistula and abnormal blood supply of the femur. The enlargement of involved limbs was diminished gradually. The angioma became completely sclerous, disappeared or decreased in size, without dwindling under pressure. In patients with venous valve reconstruction, Doppler ultrasonography showed no reflux. Follow-up for 1~7 years (mean, years) in all the 32 patients found no recurrence. Conclusions Minimally invasive treatment, including intravascular intervention, laser coagulation, sclerosing agent injection, mini-incision valve repair and so on, is effective for the management of Klippel-Trenaunay syndrome.
