Chinese Journal of Cerebrovascular Diseases 2006;3(10):433-436
Objective: To compare the therapeutic efficacy between thrombin injection and local compression on femoral pseudoaneurysms by using color Doppler flow imaging (CDFI). Methods: Thirty-eight patients with intervention-induced femoral pseudoaneurysms were randomly assigned to ultrasound-guided thrombin injection (group A, n = 19) and ultrasound-guided local compression (group B, n = 19). The volume, diameter of abnormal channel, and systolic peak velocity (SPV) of pseudoaneurysms before and after the treatment, as well as the obliterating time after the treatment were measured by CDFI. The follow-up observation was done immediately after the treatment, at day 3 and day 7. Results: The obliterating time of abnormal charmels was 4.0 ± 1.7 minutes in group A. It was significantly shorter than group B (3.6 ± 3.0 d, P=0.000). Three days later, the effective cases (19/19) in group A were significantly higher than that of group B (13/19, P=0.020) during the follow up period. Seven days later, the mean volume of hematomas in both groups was 26 ± 15 mm3, and it was significantly smaller than that before the treatment (34 ± 18 mm3, P = 0.000). The mean volume decreased 9.4 ± 8.6 mm3 in group A. There was no significant difference as compared with group B (8.6 ± 8.7 mm3, P = 0.784). One patient in group B developed deep vein thrombosis of lower limbs. Conclusion: CDFI may objectively evaluate the morphology of femoral pseudoaneurysms and the hemodynamic changes before and after the treatment. The therapeutic effect of the ultrasound-guided thrombin injection for femoral pseudoaneurysms is superior to ultrasound-guided local compression.

Objective To investigate the risk factors and prognosis of perioperative myocardial infarction in the patients undergoing noncardiac surgery. Methods Clinical data of 562 patients who had accepted non-cardiac surgery was collected and retrospectively analyzed. The risk factors, treatments and outcomes of all these patients were recorded and analyzed. Results A total of 19 out of the 562 patients had perioperative myocardial infarction ( PMI) . The incidence was 3. 4% . The mean occurrence time was (43. 5 ± 12. 7)h after operation. Eleven PMI patients (11 ∕ 19) were non-ST-segment elevation myocardial infarction and eight patients (8 ∕ 19) were ST-segment elevation myocardial infarction. Thirteen PMI patients were left coronary artery occlusion and six patients were right coronary artery occlusion. Advanced age, history of myocardial infarction, unstable angina, change of ST-T segment on electrocardiography (ECG), multivessel diseases, diabetes,hypertension,and high risk non-cardiac surgery were the risk factors of PMI and positively correlated to PMI. Sixteen PMI (16 ∕ 19) patients accepted PCI treatment and three patients (3 ∕ 19) accepted drug conservative treatment. Two patients had unstable angina attack after treatment and one patient had arrhythmia. The heart function in two patients decreased by one or more than one class within the follow up of 1 year. No patient had recurrent acute myocardial infarction or deceased during follow-up. Conclusions Many factors could lead to PMI. Making preoperative assessment, recognizing patients of high risks and dealing with patients who had PMI in time was necessary.
