[Soft-tissue defects on the dorsum of the hand by extravasation of the cytostatic agents: surgical options of treatment].
Systemic treatment with chemotherapeutic agents is often applied by infusions over peripheral vein cannulae located on the hands and lower arms. Dislocation of the cannulae or vein perforation causes an extravasation of the cytostatic agent. This complication occurs in approximately 0.1 - 6 % of intravenous treatments and is rarely noticed before administration of greater volumes. Depending on the tissue toxicity of the administered substances, the extravasation results in tissue damage of different extents. In a few cases, only conservative therapy is required. The majority of patients, however, needs immediate surgical therapy. The reason for this is the severe tissue damage caused by the chemotherapeutic agent that accumulates in the subcutaneous fat where it destroys the connective and fat tissue, nerves, vessels, tendons and muscles, impairing the functionality of the entire hand and arm. In very severe cases, partial or complete amputation of the extremity is the only treatment. The application of antidotes has been discussed controversially and is not a standard procedure. In the past 11 years, 18 patients with extravasations of chemotherapeutics on the dorsum of the hand were admitted to our department. After radical debridement no primary closure of the resulting defect was advisable in the first operation. In all cases we could later perform a stable wound closure. In our opinion, this two-step procedure with primary radical debridement, temporary wound coverage and later wound closure should be performed regularly.
