Towards safer reoperations: special aspects in aortic dissection☆

Acute type A aortic dissection: long-term results and reoperations.

OBJECTIVES The objective of this study was to report long-term results and incidence of reoperations after surgery for acute type A dissection. METHODS All 232 consecutive patients who underwent surgery for acute type A aortic dissection from 1972 to April 2011 were included. Patient, procedural and follow-up information was obtained from hospital records. RESULTS Mean age was 57.9 years (s...

management of aortic dissection

Technical aspects of total aortic repair in the surgical management of acute type A aortic dissection.

Traditional surgical techniques for the management of acute type A aortic dissection (ATAAD) focus on open distal anastomosis with or without hemiarch replacement under a period of deep hypothermic circulatory arrest. This is associated with high rates of false lumen (FL) patency, which exposes the patient to the risk of ongoing end-organ malperfusion and to the formation of complex arch and th...

Risk of late reoperations in patients with acute type A aortic dissection: impact of a more radical surgical approach.

OBJECTIVE To evaluate the incidence and risk factors for reoperations on the pre-isthmic aorta after repair of type A acute aortic dissection. METHODS From January 1979 to December 1996, 178 patients (125 males and 53 females with a mean age of 57 +/- 9 years) underwent emergency surgery for acute type A aortic dissection with an overall operative mortality rate of 21%. One hundred and forty-...

Towards Safer Spreadsheets!

Professional programmers are well aware that debugging, testing, code inspection, etc. are part and parcel of software development. Requiring end users to carry out the same activities to reduce spreadsheet errors might be asking too much. For one thing, they lack the expertise and for another, they might not be willing to invest the time and effort required by these activities. For example, te...
