OBJECTIVE To determine whether graft survival over a 5-year follow-up period using corneal tissue from donors older than 65 is similar to graft survival using corneas from younger donors. DESIGN Multicenter prospective, double-masked, controlled clinical trial. PARTICIPANTS One thousand ninety subjects undergoing corneal transplantation for a moderate-risk condition (principally Fuchs' dyst...
Aplastic anemia is usually treated with immunosuppression or allogeneic transplant, depending on patient and disease characteristics. Syngeneic transplant offers a rare treatment opportunity with minimal transplant-related mortality, and offers an insight into disease mechanisms. We present here a retrospective analysis of all syngeneic transplants for aplastic anemia reported to the European G...
BACKGROUND In this study, the relationship between patency of saphenous vein (SV) graft and different sizes of aorta wall punches was investigated during the follow-up period after coronary artery bypass graft surgery. We also evaluated the other possible factors affecting SV graft patency. METHODS This study consisted of 266 consecutive and symptomatic patients with postoperative angiography...
Background & Aim: Previously, patients with end stage renal failure(ESRF) and lower urinary tract abnormality(LUTA) were often considered high risk for renal transplantation. In order to examine the degree of risk, 48 patients who received renal transplants in Labafi Nejad Hospital were evaluated between 1986 and 2003. Patients & Method: In this retrospective cohort study, the mean age of t...
Vein graft failure following bypass surgery is a frequent and important clinical problem. The vascular injury caused by arterialization is responsible for vein graft intimal hyperplasia, a lesion generated by medial smooth muscle cell proliferation and migration into the intima, increased extracellular matrix deposition, and formation of a thick neointima. Development of the neointima into a ty...
Purpose and Methods: Penetrating keratoplasty (PK) in herpes simplex keratitis (HSK) is increasingly performed not only for visual purposes but also to remove viral antigen from the cornea and to reestablish the structural integrity of the eyes. With the improvement of medical management and surgical techniques which lead to a higher survival rate of the graft, PK in HSK still carries a high co...
Outcomes of allogeneic hematopoietic stem cell transplantation (AHSCT) using HLA-half matched related donors (haploidentical) have recently improved due to better control of alloreactive reactions in both graft-versus-host and host-versus-graft directions. The recognition of the role of humoral rejection in the development of primary graft failure in this setting has broadened our understanding...
BACKGROUND The majority of distal biceps tendon injuries can be repaired in a single procedure. In contrast, complete chronic tears with severe tendon substance deficiency and retraction often require tendon graft augmentation. In cases with extensive partial tears of the distal biceps, a human dermal allograft may be used as an alternative to restore tendon thickness and biomechanical integrit...
The number of Kidney transplants has increased in last decades for many advances in diagnostic and therapeutic reasons. Kidney transplantation results in superior life expectancy and better quality of life if compared to dialysis treatment for patients with endstage renal failure. The success of graft survival after kidney transplantation is closely associated with early graft function based on...
Objective To compare the outcomes of securing full-thickness skin grafting (FTSG) with through-and-through mattress suturing versus the classic tie-over and pressure dressing and identify the associated risk factors of graft failure. Methods A single-institution, retrospective case series of patients who had undergone excision of head and neck skin lesions requiring FTSG over a 10-year period...
