Objective To summarize the clinical characteristics of and therapeutic approaches to deep venous thrombosis(DVT)caused by pelvic tumors,in the fact that some patients with pelvic tumors may present DVT as the first sign of the tumor. Methods The clinical data of 36 patients admitted between January 1997 and April 2009 suffering from pelvic tumor induced DVT were analvzed retrospectively.Result In all of these 36 patients,the occurrence of limb sweUing wag chronic and progressive with insidious onset.Regular DVT treatment Was given to 25 cases yielding no effect before the cause Was revealed.Ultrasound and CT were used for detection of the pelvic tumor.and compression of the iliac vein by the tumor was detected in an the cases.Pelvic tumor resection with iliac vein ligation was done in 29 cases(5 cases had iliac artery reconstruction with prothesis graft),in the remaining cases the pelvictumors were left untreated. Elastic stocking compression and venotropie preparations. microcirculation-improving agents were routinely applied in all the pafients.All the cases got improvement with different degrees.Conclusion DVT Call be a precursor of pelvic tumors.A thorough consideration of this posibility Is important when limb swelling Was chronic and progressive,or no improvement was observed after regular DVT treatment.Surgical resection of the pelvic tumors and conservative therapy of the involved limb is the therapeutic principle.
