Tracheal replacement by autogenous aorta
BACKGROUND Tracheal defects may occur after trauma or prolonged intubation. Resection of tracheal tumors also poses a major challenge for substitution. In an effort to solve this problem, different techniques have been tried with little success. We report on a new animal model which showed acceptable results with fewer complications. METHODS We replaced 5 cm of cervical trachea in 10 dogs wit...
متن کاملExtended replacement of the thoracic aorta.
OBJECTIVES We present our experience of total aortic arch replacement. METHODS Twenty-nine patients (21 males and 8 females; mean age 63.3 ± 13.3 years) with extended thoracic aortic aneurysms underwent graft replacement. The pathology of the diseased aorta was non-dissecting aneurysm in 11 patients, including one aortitis and aortic dissection in 18 patients (acute type A: one, chronic type ...
متن کاملProsthetic replacement of the ascending aorta increases wall tension in the residual aorta.
BACKGROUND Prosthetic replacement of the ascending aorta with nonelastic vascular grafts impairs the local Windkessel function. Whether this increases wall tension in the remaining aorta is still a not completely investigated hypothesis but is of clinical relevance with respect to postprocedural development of aneurysms and dissections, especially in the proximal descending aorta. METHODS Fre...
متن کاملSurgical Experience of Ascending Aorta and Aortic Valve Replacement in Patient with Calcified Aorta
BACKGROUND The conventional method of aortic cross-clamping is very difficult and increases the risk of cerebral infarct due to embolism of the calcified aorta in these patients. Accordingly, we analyzed our experience with 11 cases of ascending aorta and aortic valve replacement with hypothermic circulatory arrest. MATERIALS AND METHODS From January 2002 to December 2009, 11 patients had asc...
متن کاملGiant pseudoaneurysm of the ascending aorta after double-valve replacement.
A 47-year old man presented with a large chest swelling 10 months following aortic and mitral valve replacement. Computed tomography revealed a huge ascending aortic pseudoaneurysm (Fig. 1A and B). After establishing hypothermic circulatory arrest through an axillary-femoral bypass, a median sternotomy was performed. The defects were directly closed using two interrupted, pledgeted 4-0 Prolene ...
