Endovascular repair of a tuberculous aneurysm of descending thoracic aorta / 中华医学杂志(英文版)

Tuberculous aortic aneurysm (TBAA) is an extremely rare clinical event with life-threatening implication. Management for this condition is challenging and its therapeutic option has not been yet established. A few recent reports described endovascular repair rather than open surgery as the method for treatment. Although this remains controversial, endovascular exclusion has been gaining acceptance for some surgeons. We present a case of TBAA who was treated by endovascular stent grafting for a descending thoracic aortic aneurysm with simultaneous anti-tuberculous medication. The outcome was favorable.

Evaluation of efficacy of the anticoagulation and thrombolysis for deep venous thrombosis via local vein approach and peripheral vein approach / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the efficacy of anticoagulation and thrombolysis for deep venous thrombosis via local vein approach and peripheral vein approach to guide clinical treatment.</p><p><b>METHODS</b>There were 225 patients with deep venous thrombosis admitted from January 2001 to May 2008. The cases were divided into two groups by therapy procedures. The patients in group A were treated by deep femoral vein catheter-directed anticoagulation and thrombolysis, including a total number of 71 patients, with right lower extremity in 20 patients, left lower extremity in 47 patients and bilateral lower extremities in 4 patients. One hundred and fifty-four patients were included in group B with anticoagulation and thrombolysis through peripheral vein, among them right lower extremity in 27 patients, left lower extremity in 121 patients and bilateral lower extremities in 6 patients. The efficacy was evaluated and compared by observing clinical symptoms and measuring of changes in limb circumference.</p><p><b>RESULTS</b>Symptoms were alleviated in all patients in 3 d after the treatment, but the efficacy of group A was better than group B (94.4% vs.69.5%, P < 0.01). The efficacy of group A was also better than group B in 7 days after treatment, but with no significant difference (85.9% vs. 75.3%, P > 0.05). A mean follow-up period was (43 ± 18) months. There was no significant difference in incidence of complication and recurrence between two groups.</p><p><b>CONCLUSIONS</b>The earlier efficacy of anticoagulation and thrombolysis via femoral vein approach is better than via peripheral vein approach in earlier period of deep venous thrombosis. While peripheral intravenous therapy has also good results after long-term treatment.</p>

Inflammatory abdominal aortic aneurysm: clinical features and long term outcome in comparison with atherosclerotic abdominal aortic aneurysm / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Inflammatory abdominal aortic aneurysms (IAAAs) are rare but distinct clinical entities of atherosclerotic abdominal aortic aneurysms (aAAAs). In this study we report a 20-year single institution experience for IAAA and analyze their clinical features and long term outcome in comparison with aAAA.</p><p><b>METHODS</b>Between 1988 and 2008, 412 cases of abdominal aortic aneurysms (AAAs) underwent elective surgical operations, 11 (2.7%) of whom were diagnosed as IAAAs and 389 (94.4%) were diagnosed as aAAAs. The former group was matched in a case control fashion to a group of 33 patients with aAAAs having similar characteristics of age, gender, and preoperative risk factors. All available clinical, pathologic, and postoperative variables were retrospectively reviewed, and the two groups were compared.</p><p><b>RESULTS</b>The two groups did not differ significantly in clinical characteristics and preoperative risk factors, although patients with IAAAs were significantly more symptomatic (100% vs. 42.4%, P = 0.001) and had larger aneurysms on admission ((7.4 +/- 0.7) cm vs. (6.3 +/- 0.9) cm, P = 0.006). In IAAAs, the preoperative erythrocyte sedimentation rate was found to be significantly elevated compared to aAAA group ((44.5 +/- 9.1) mm/h vs. (11.4 +/- 5.4) mm/h, P < 0.05). Surgical morbidity and mortality rates did not differ between the two groups. The operation time for patients with IAAAs was significantly longer than that for patients with aAAAs ((308 +/- 36) minutes vs. (224 +/- 46) minutes, P < 0.05), but the cross-clamp time was similar in both groups ((41.5 +/- 6.2) minutes vs. (41.8 +/- 6.2) minutes, P = 0.92). A five-year survival rate analysis showed no significant difference between the two groups (P = 0.711).</p><p><b>CONCLUSIONS</b>Despite having more symptoms, larger size and longer operation time, patients with IAAA can now be treated with approaches that cause low morbidity and mortality, similar to patients with aAAA. Long term outcome of IAAA patients is of no difference from aAAA patients.</p>
