[The study of different operative style for abdominal aortic aneurysm during surrounding operation].

Objective: To compare the the similarities and differences during the surrounding operation of endovascular repair (EVAR) and open surgical repair (OSR) for abdominal aortic aneurysm.

Methods: 112 patients with abdominal aortic aneurysms (AAA) were selected from 2004 to 2009: among them, 66 patients were treated with EVAR, 46 patients with OSR. Data of two groups were collected and analyzed during surrounding operation.

[Analysis of death-related factors of type B aortic dissection treated medically during the acute phase].

Objective: To analyze the death-related risk factors of type B aortic dissection treated medically during the acute phase (symptoms presenting within 14 d), and to determine the predictors of surgical indications for acute type B aortic dissection.

Methods: Clinical data of 42 patients with acute type B aortic dissection admitted from January 2007 to May 2009 was retrospectively reviewed. There were 33 male and 9 female with a mean age of (50 +/- 12) years old.

Method: The clinical data of 37 patients treated from January 1996 to August 2007 was retrospectively reviewed.

Results: Of the cases, 19 (51.
