conclusions in our patients, the ra grafts had an acceptable patency rate in 2 to 5 years’ follow-up. although the sv grafts had a relatively higher patency rate than ra grafts in our asymptomatic patients, the patency rates in ra and sv grafts were close to each other. the ra graft function was poor in the patients with a higher number of risk factors and in the females. background patency of ...

The left subclavian artery (LSA) origin can be intentionally covered by stent grafts, to provide adequate proximal landing zones during thoracic endovascular repair for Stanford type B aortic dissections (TBADs). To preserve the LSA, a novel single branched graft, named “Castor” was designed and clinical trial conducted investigate its suitability. From April 2013 March 2015, 73 patients with T...

The study seeks to empirically apply multiple performance evaluation techniques, including traditional approach to assess the performance of government projects. Studies have shown that while there is an increase in improved project management methods, tools and techniques, including performance evaluation techniques, organizations including governments are still relying on outdated or insuffic...

Introduction: In order to achieve a higher success rate for tympanoplasty, different techniques have been developed, and a wide variety of grafting materials have been developed. One of the techniques currently receiving considerable attention involves not lifting the remaining of eardrum from the malleus and embedding the graft underneath in order to repair the eardrum correctly in its origina...

A short cold ischemic time, an optimal HLA match and other pre-transplant factors are in a key role in the success of kidney transplantation. Over the past decades, the acute rejection rate of kidney transplants has fallen dramatically and the 1-year graft survival rate has increased to 90% in transplantations with deceased donors and 95% with living related donors. This increase in graft survi...
