Low-molecular-weight Heparin for Preventing Deep-vein Thrombosis after Regional Operations for Rectal Carcinoma

Objective To evaluate the efficacy and safety of low-molecular-weight heparin(LMWH) in preventing deep-veint hrpmbosis(DVT) after regional operations for rectal carcinoma. Methods From October 1999 to December 2002,we performed regional operations for rectal carcinoma for 37 controlpatients and for 33 patients who had been given low-molecular-weight heparin for preventing deep-vein thrombosis.All patients received colar ultrasonic diagnosis of the limbs after operation.
