Purpose: To assess the role of OR in treatment of AAA patients, we reviewed the indications and our current results of OR of AAA. Methods: We retrospectively investigated the database of 366 patients (mean age, 68.3±8.7 years, male 86%) who underwent open surgical (n=291, 80%) or endovascular treatments (n=75, 20%) of AAA in a tertiary referral center between Sep. 2003 to Aug. 2010. Treatment-related morbidities and mortality rates within 30 days were investigated according to the indications for treatment, clinical features, anatomic location, and underlying causes of AAA. Results: According to the location of AAA, we treated 343 (94%) infrarenal, 17 (5%) juxtarenal and 6 (2%) suprarenal AAAs. Underlying causes of AAA were degenerative (90%), infected (3%), inflammatory (3%), Marfan’s syndrome (2%), and vasculitis (0.5%). Clinically, 338 (92%) were non-ruptured and 28 (8%) were ruptured AAAs. 75% of patients were treated with OR after the inception of reimbursement of aortic device while 25% of patients were treated with EVARs. The operative mortality rates of OR was 0.4% in patients with non-ruptured infrarenal AAA, 0% in patients with non-ruptured juxta- and suprarenal AAA and 21.4% in ruptured AAA patients. Conclusion: In an era of endovascular treatment of AAA, we have experienced excellent surgical results after OR in patients with non-ruptured AAA with various clinical features. Though EVAR is rapidly replacing OR in treatment of infrarenal AAAs, OR has its own role in treatment of AAA patients with unfavorable conditions for EVAR. The role of OR should not be underestimated.

Purpose: Between combined and staged operations of carotid endarterectomy (CEA) and coronary artery bypass grafting (CABG) for patients with concurrent coronary and carotid disease, each treatment strategy has its own advantages and disadvantages. We attempted to compare early surgical results between the two operations. Methods: We retrospectively reviewed medical records of 71 patients who underwent either combined CEA & CABG (n=37) or staged CABG & CEA (n=34) in a single institute between January 2001 and March 2010. After comparing patients’ demographics and preoperative neurologic and cardiac status, we compared early (<1 month) postoperative cardiac or neurologic complications and surgical mortality between the 2 groups. Results: There was no significant difference in patients’ demographics and indications for operation the between 2 groups. There were 2 (5.4%) cases of postoperative stroke in combined groups and 1 (2.9%) in staged group. However, there was no myocardial infarction or death. In staged operation group, during the interval time between the two operations, 5 cases (14.7%) of stroke developed, of which, all patients recovered without any sequelae by anticoagulation. Conclusion: After experiencing low postoperative cardiac or neurologic morbidity or mortality after combined CABG and CEA, we conclude that combined CABG and CEA was a safe and feasible treatment option for patients with neurologic symptoms and in stable cardiac status. In the staged operation group of patients, we observed development of neurologic events during the interval period between CABG and CEA. To attain optimal treatment strategy in asymptomatic patients, further prospective study would be required.

BIT(Built-In Test)란 S/W 또는 H/W 의 기능 및 상태를 진단하고 오류에 대응하기 위한 방법론으로 기능에 대한 신뢰성 및 빠른 오류 복구를 보장하기 때문에 다양한 분야에서 BIT 처리를 통해 시스템의 안정성을 높이고 있다. 현업에서의 BIT 는 도메인 특성에 따라 처리해야 하는 작업의 변화가 크기 때문에 구조화 되지 않은 형태로 각각 개발되고 있다. 따라서 BIT 개발 시 반복적인 작업이 수반되며 처리 과정의 수정 또는 처리 범위의 확장을 위해서는 많은 시간 및 인력이 요구된다. 이 에 본 논문에서는 BIT 처리를 구조화하기 위하여 처리과정에 필요한 정보들을 일반화된 형태로 기록할 수 있도록 하는 BIT 처리 명세 방안과 BIT 처리 명세를 기반으로 한 자동 코드 생성 체계를 제안한다. 이를 통해 개발 과정의 편의성과 생산성을 향상하고 BIT 처리의 유연성과 확장성을 높일 수 있다.
