Objective To explore the diagnosis and treatment of ruptured abdominal aortic aneurysm (RAAA). Methods Between January 1996 and December 2009, 14 patients with RAAA were treated. There were 13 males and 1 female with an average age of 65 years (range, 50-82 years). The main cl inical manifestations were abdominal pain and/or back pain. Ten cases had low blood pressure or shock. All cases were accurately diagnosed with CT, Doppler ultrasonography,or operation. The aneurysm diameter was from 4.5 cm to 8.0 cm. Eleven cases were treated by conventional operation, 1 by endovascular aortic repair, 1 by conservative treatment, and 1 case died after admission treatment. Results Perioperative death occurred in 6 cases (mortal ity rate was 50%) in 12 surgical patients. One case died after conservative treatment. The overall mortal ity rate was 57.14% (8/14). The causes of death included circulatory failure in 2 cases and multiple organ failure in 4 cases. The other 6 cases were cured. The postoperative hospital ization days were 12 to 34 days (14 days on average). A total of 4 cases were followed up 11 to 40 months without related compl ication. Conclusion Surgical treatment is still a main method to treat RAAA. Early diagnosis, appropriate resuscitation, and urgent surgical repair are crucial to reduce the mortal ity rate of RAAA.
Objective To summarize the advancement of hereditary thrombophilia. Methods Relevant literatures about hereditary thrombophilia published recently domestic and abroad were reviewed and analyzed. Results The hereditary risk factors of venous thromboembolism were different among different races. In western population, the main risk factors were activated protein C resistance (APC-R) and mutation of factor V Leiden, methylene tetrahydrofolate reductase polymorphism (C677T) and prothrombin G20210A. While in Chinese population, the disorder of protein C system and hyperhomocysteinemia were the major genetic risk factor. The existence of multiple genetic risk factors increased the incidence of primary and recurrent venous thromboembolism. Conclusion Further study on the relations between the hereditary risk factors and thrombophilia will be very important for prediction and prevention of the venous thromboembolism.
目的 探讨原发性主动脉消化道瘘的诊断和治疗。方法 报道1例原发性主动脉消化道瘘的诊治经过,并复习有关文献。结果 本例为67岁男性患者,以“腹部不适伴反复便血7个月”入院。急诊行剖腹探查，结合术中肠镜发现腹主动脉瘤十二指肠瘘。十二指肠第3段瘘口用5-0普理灵修补缝合； 行腹主动脉瘤切除，用16 mm×8 mm分叉涤纶人造血管行腹主动脉-人造血管-左髂总动脉、右髂外动脉吻合。术后静脉使用三代头孢抗生素3周,后改用口服抗生素，无发热，切口一期愈合，顺利出院。结论 原发性主动脉消化道瘘罕见、死亡率高,应注意与主动脉瘤患者的消化道出血鉴别。及时诊断和快速外科治疗是提高存活率的关键。
In order to evaluate the effect and indication of three kinds of deep-venous valve reconstruction surgery, 62 cases with venous reflux disease of the leg had been treated from Jan. 1992 to Jun. 1996. All the patients had varicose vein and tingle in varying degrees, besides swelling in 30 cases, pigmentation in 28 cases, ulcer in 14 cases. The course of disease ranged from 1 to 30 years (averaged 14.6 years). METHOD: 14 cases were treated by ringing of the superficial femoral venous 1st valve, 1 case was treated by repairing of the superficial femoral venous 1st valve, 47 cases were treated by formation of substitute valve outside the popliteal vein. The symptoms of all the patients were alleviated with an average follow-up for 20 months. Fourteen cases with ulcer were healed compeletely and no recurrence. The conclusion were: 1. ringing and repairing of the venous valve were suitable for level I-II venous valvular incompetence. 2. formation of substitute valve outside the popliteal vein was suitable for level III-IV venous valvular incompetence or congenital valvular defect. 3. the width of the ringing material should be increased to 2 cm according to the pathological basis. 4. both femoral veins should be ringed in the treatment of primary valvular incompetence of double deep vein deformity. 5. the formation of substitute valve outside the popliteal vein was also available in the treatment of popliteal vein with many branches.
Objective To explore the diagnosis and treatment for ruptured abdominal aortic aneurysm （RAAA）. Methods The clinical data of 20 patients with RAAA from January 2000 to December 2010 were analyzed retrospectively．Results There were 18 males and 2 females．The age was 31-82 years with an average 65.4 years．All the patients were abdominal pain and （or） back pain．Eleven cases had low blood pressure or shock．Seven cases had a history of abdominal aortic aneurysm．All the cases were accurately diagnosed by CTA，Doppler ultrasonography or operation．Nineteen cases were treated by conventional operation，1 by endovascular aortic repair．Survival of 16 cases recovered smoothly. Perioperative death occurred in 4 cases，mortality rate was 20% in 20 patients with RAAA．The causes of death included circulatory failure in 1 case and multiple organ dysfunction syndrome in 3 cases．Conclusions Surgery treatment is an effective treatment for RAAA．Early diagnosis and urgent surgical repair are crucial to reduce the mortality of RAAA．
Objective To explore the value of color Doppler ultrasonography and plasma D-dimer in diagnosis of lower limb deep venous thrombosis (DVT).Methods The clinical data of 70 cases of patients with lower limb DVT diagnosed clinically were retrospectively studied. The lower limb venous of each patient was examined by color Doppler ultrasonography and the plasma level of D-dimer were measured, furthermore the plasma levels of D-dimer in different phase and different type of thrombosis were compared. Results The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of plasma D-dimer and ultrasonography examination in lower limb DVT were 100%, 66.7%, 97.0%, 100%, and 97.1%, and 98.4%, 83.3%, 98.4%, 83.3%, and 97.1%, respectively. The plasma D-dimer in acute phase 〔(6 451±4 012.22) μg/L〕 and subacute phase 〔(2 063±1831.35) μg/L〕 of lower limb venous thrombosis were significantly higher than that in normal control group 〔(310±66.70) μg/L〕, Plt;0.01 and Plt;0.05, which was not different from that in chronic phase 〔(466±350.52) μg/L〕. Meanwhile, the plasma D-dimer in mixed limb venous thrombosis group 〔(4 464±3 753.16) μg/L〕 and central limb venous thrombosis group 〔(2 149±1 911.53) μg/L〕 were significantly higher than that in control group (Plt;0.05 and Plt;0.01), which was not different from that in peripheral limb venous thrombosis group 〔(560±315.62) μg/L〕. Conclusion Color Doppler ultrasonography is an optimal method and the plasma D-dimer is a predictive index in diagnosis of lower limb DVT.
