Treatment of a femoral venous aneurysm with foam-sclerotherapy

Cesarone M. R., Belcaro G., Nicolaides A. N., Geroulakos G., Caciagli F., Cornelli U.

Venous aneurysms are uncommon. Venous dilatation and large varices could be treated with injections of foam and sclerosing agents followed by local compression which obliterate or thrombose the aneurysmal space. However, the use of foam-sclerotherapy to obliterate venous aneurysms has never been reported before. The obstruction or sclerosis of the aneurysmal space should be obtained without altering the femoral flow. The patient is a 65-year old lady without history of trauma involving the femoral region. A compressible lump is present at the third, internal part of the left femoral fold. The lump is painless and easily obliterated by compression. Color duplex shows a large cavity (4 x 4 x 6 cm) and venous flow is visible. Flow produces a venous jet, visible with color and ejecting from the common femoral vein. A first injection is made under ultrasound guide using a foaming agent: 10 ml of foam including 4 ml of 3% sclerosing solution are injected. During the injection the femoral vein is compressed with the probe to avoid passage of the sclerosing foam into the femoral vein. After 2 weeks, ultrasound indicate only a partial occlusion of the aneurysm. The procedure is repeated and after 2 more weeks the ultrasound scan shows a complete occlusion of the aneurysm. The femoral vein and the long saphenous vein are patent. After 12 weeks the situation is unchanged and the results appear to be permanent. This new method, never described before is an important, minimally invasive method in case of venous aneurysms. Results from larger studies should be available to define indications and modalities of treatment.
