mycotic pseudoaneurysm of the ascending aorta is rare in patients undergoing coronary artery bypass graft (cabg) and usually caused by staphylococcus aureus. we describe a patient with a mycotic pseudoaneurysm of the ascending aorta at the proximal vein graft anastomosis site after cabg. culture from the sinus tract of the sternum and from the aneurysm sac was klebsiella pneumoniae. surgical te...

In this work, repaired crack in 6061T6 aluminum plate with composite patches presented, firstly we determine the displacement, strain and stress, also the first six mode shape of the plate, secondly we took the same model adding central crack initiation, which is located in the center of the plate, its seize vary from 20 mm to 60 mm and we compare the first results with second. Thirdly we repai...

Objectives: Truncus arteriosus (TA) continues to be associated with signi®cant morbidity and mortality, but there have been clinically signi®cant improvements with early repair. Methods: Sixty patients underwent physiological correction of TA between November 1978 and January 2000. The average age was 76 days (range, 3 days±20 months). Associated cardiac anomalies were frequently encountered, t...

The aim of this study was to evaluate the resorption process during the repair of autogenous bone grafts with or without coverage by an expanded polytetrafluoroethylene (e-PTFE) membrane in female rats with estrogen deficiency using the immunohistochemical technique. Eighty female rats were randomly divided into two groups (OVX and SHAM). The 40 female rats in the OVX group were subjected to ov...

For more than a century, since the introduction of modern hernia repair by Basinni, technical aspects of hernia surgery have been surrounded by controversies. The purpose of this article is to examine these controversies with special attention to (a) mechanical versus degenerative nature of hernias, (b) traditional tissue approximation repair (tension repair) versus tension-free mesh repair, (c...

Objectives: Pulmonary valve insufficiency and right ventricular dysfunction may contribute to early and late morbidity and mortality after repair of Tetralogy of Fallot. Right ventricular dysfunction may be attributed to ventriculotomy incision, especially, when it is combined with a transannular patch as employed in the transventricular repair. Transatrial/transpulmonary approach without ventr...

Various surgical techniques have been described to repair congenital supravalvular aortic stenosis, but the best technique is still controversial. The three-patch repair reconstructs a symmetric aortic root and is supposed to restore a normal physiology. We present two successfully operated patients who had congenital supravalvular aortic stenosis using symmetric three-patch repair. We will dis...

Repair of degenerative mitral insufficiency has extensively been shown to be superior to replacement. In the majority of cases, the culprit lesion is limited to the posterior mitral leaflet (PML), which is treated with quadrangular resection of the prolapsing PML, annular plication of the corresponding segment of the annulus, and prosthetic annuloplasty. Anterior mitral leaflet (AML) prolapse i...
