Outcomes of Planned Two-Stage Hybrid Aortic Repair With Dacron-Replaced Proximal Landing Zone

Two stage hybrid approach for complex aortic coarctation repair

BACKGROUND Management of an adult patient with aortic coarctation and an associated cardiac pathology poses a great surgical challenge since there are no standard guidelines for the therapy of such complex pathology. Debate exists not only on which lesion should be corrected first, but also upon the type and timing of the procedure. Surgery can be one- or two-staged. Both of these strategies ar...

Endografting in the aortic arch - does the proximal landing zone influence outcome?

OBJECTIVES To analyse early and midterm results of thoracic aortic endografting (TEVAR) in the aortic arch. METHODS Between January 1997 and February 2009 178 patients received TEVAR in the aortic arch at our institution. This population was subdivided into four groups according to the proximal landing zone (LZ) classification in the aortic arch by Ishimaru et al. and a retrospective analysis...

Hybrid Three-Stage Repair for Extended Thoracoabdominal Aortic Aneurysm: Report of A Case.

A 67-year-old man complicated with back pain. The computed tomography (CT) scan showed an extended thoracoabdominal aneurysm. We successfully performed a three-stage hybrid repair using the visceral-renal debranching technique. For the first stage operation we performed Y-grafting with the debranching technique to create a distal landing zone. Then, for the second stage operation, we performed ...

A Two-Stage Hybrid Flowshop Scheduling Problem with Serial Batching

In this paper the problem of serial batch scheduling in a two-stage hybrid flow shop environment with minimizing Makesapn is studied. In serial batching it is assumed that jobs in a batch are processed serially, and their completion time is defined to be equal to the finishing time of the last job in the batch. The analysis and implementation of the prohibited transference of jobs among the mac...
