[Vena iliaca externa thrombosis after open operation of the bladder and prostate]

Since 1986, we have performed total cystectomy or partial cystectomy with ureteroneocystostomy in 64 cases and prostatectomy in 182 cases. 5 cases developed vena iliaca external thrombosis (VIET) or thrombophlebitis postoperatively. Three of them recovered after treatment, and 2 died of pulmonary embolism 7 and 16 days after operations. VIET is a very serious complication. Once develops pulmonary embolism, the patient may die soon. We suggested that patients be encouraged to increase limbs activities, be given medicines of antilipemic and antiatherogenic preoperatively. And during the surgical operation, patients' blood pressure should be kept steady, and hypopietic shock should be avoided as long as possible. The vena iliaca external should never be constricted when a deep hook is used for exposure or gauze is used to stop bleeding. After operation, the patient should be encouraged to exercise on bed or around bed as early as possible, so as to increase venous flow. The veins of lower limbs should be avoided by using infusion. Styptic should not be applied abusively. Infusion of dextranum-40 and orally taking of persantinum may also be used to prevent this kind of complication.
