[Postoperative pulmonary embolism in neurosurgical practice: report of two cases].
Pulmonary embolism following postoperative deep venous thrombosis is a very serious complication with a high mortality rate. Though this disorder has been thought to be rare in Japanese, its occurrence seems to be increasing recently because of changes in eating habits, increase of average age and the frequent practice of venous catheterization. Two cases of the pulmonary embolism following deep venous thrombosis after surgery are reported, and possible causes of the deep venous thrombosis are discussed. Case 1: A 48 year-old obese female was operated on for a posterior fossa dural arteriovenous malformation. On the 4th postoperative day, she developed a pain and swelling in the left leg and low back pain. On the 18th postoperative day, she fell into a state of shock following the sudden onset of a severe back pain and respiratory distress. After diagnosis of the pulmonary embolism, she was immediately treated with urokinase, warfarin and aspirin. Her obesity was considered to be one of the risk factors of the postoperative deep venous thrombosis. Case 2: A 62 year-old female with a ruptured cerebral aneurysm could not get out of bed because of postoperative mental disturbance. A central venous pressure catheter was inserted into the right femoral vein for two weeks postoperatively. One month after surgery, she complained of swelling and a dull pain in the right leg without cardiorespiratory symptoms. Lung perfusion scintigraphy showed asymptomatic pulmonary embolism. She was treated immediately. Both long bed rest and femoral venous catheterization were considered as risk factors possibly leading to deep venous thrombosis.(ABSTRACT TRUNCATED AT 250 WORDS)
