Fifty consecutive patients undergoing abdominal aortic aneurysm resection were studied prospectively for the presence of deep venous thrombosis (DVT) after surgery.
Bilateral venography was performed 5 days after surgery in all patients. There were 42 men and 8 women, with a mean age of 70 years (range 60 to 83 years). No patients received DVT prophylaxis before surgery.
Nine (18%) of 50 patients had a venogram positive for acute DVT. Nine (21%) of 42 men and none of eight women had DVT. Six patients had DVT in the left leg and three patients in the right leg. No patients had symptoms to suggest DVT. Seven (78%) of the nine patients with DVT had thrombi in the calf veins and two patients (22%) had thrombi in the more proximal venous segments, representing 14% and 4% of the entire series, respectively. No clinically evident pulmonary emboli were observed.
Eighteen percent of 50 consecutive patients undergoing abdominal aortic aneurysm resection had DVT. Because of this high incidence, a study should be undertaken to determine whether DVT prophylaxis can lower the incidence of DVT after abdominal aortic aneurysm resection.
对连续50例行腹主动脉瘤切除术的患者进行前瞻性研究，以观察术后深静脉血栓形成（DVT）情况。
所有患者于术后5天行双侧静脉造影。其中男性42例，女性8例，平均年龄70岁（60至83岁）。术前无患者接受DVT预防措施。
50例患者中9例（18%）静脉造影显示急性DVT阳性。42例男性中有9例（21%）发生DVT，8例女性中无一例发生。6例患者左下肢出现DVT，3例患者右下肢出现DVT。无患者有提示DVT的症状。9例DVT患者中7例（78%）血栓位于小腿静脉，2例患者（22%）血栓位于更近端静脉段，分别占整个研究系列的14%和4%。未观察到临床明显的肺栓塞。
连续50例行腹主动脉瘤切除术的患者中18%发生DVT。鉴于这一高发病率，应开展一项研究以确定DVT预防措施能否降低腹主动脉瘤切除术后DVT的发生率。
