Comparison of clinical outcomes between ABO-compatible and ABO-incompatible spousal donor kidney transplantation

BACKGROUND: Kidney transplantation (KT) is the treatment of choice for end-stage renal disease patients. The spouse is a major donor in living KT. Clinical outcomes of spousal donor KT are not inferior to those of living related donor KT. In this study, we compared clinical outcomes between ABO-compatible (ABOc) and ABO-incompatible (ABOi) spousal donor KTs. METHODS: Thirty-two cases of spousal donor KT performed from January 2011 to August 2013 were analyzed retrospectively. Twenty-one ABOc KTs and 11 ABOi KTs were performed. We investigated patient survival, graft survival, acute rejection, graft function, and complications. RESULTS: During follow-up, patient and graft survival rates were 100% in both groups. There were no significant differences in the incidence of delayed graft function, acute rejection, and the change in graft function between the 2 groups. Medical and surgical complications were not significantly different between the groups. CONCLUSION: The clinical outcomes of ABOc and ABOi spousal donor KTs were equivalent. In ABOi KT, an emotionally motivated spousal donor KT may be a good alternative to the problem of the absolute shortage of kidney donations.

Successful Treatment of Lower Extremity Malperfusion Caused by Acute Aortic Dissection / 대한흉부외과학회지

Organ malperfusion may mask the presence of aortic dissection and is one of major cause of death in patient with aortic dissection. Several key mechanism appear to contribute to the development of malperfusion, therefore optimal choosing of treatment is necessary to obtain better result. In cases of extremity malperfusion, open bypass procedures have been used for primary treatment, but noninvasive interventional procedures are also recommended as good alternatives in some cases. Here in, we report a case of successful aortic replacement followed by stent insertion in patient with extremity malperfusion caused by acute aortic dissection.

Trapping of Massive Thrombus in an Inferior Vena Cava Filter: Treatment with Additional Filter Placement and Aspiration Thrombectomy

For the patients suffering from extensive deep vein thrombosis (DVT), the placement of an inferior vena cava (IVC) filter in conjunction with anticoagulant therapy has been used to prevent pulmonary embolisms. However, for the patients who anticoagulant is contraindicated or if this is complicated, the use of an IVC filter without concurrent anticoagulation may become the sole treatment for pulmonary embolisms. In this situation, the thrombi trapped in the IVC filter may cause significant clinical problems. We report here on a case of IVC filter thrombosis that was successfully treated by aspiration thrombectomy after placing another filter proximal to the previous filter.

Retrospective Study Comparing Cyclosporine Microemulsion and Tacrolimus in Living Donor Renal Transplant Recipient / 대한이식학회지

PURPOSE: In order to achieve an adequate immunosuppression and avoid side effects of immunosuppressant, various combination of immunosuppressant have been tried. METHODS: To review the result of living donor renal transplantation according to the type of calcineurin inhibitor (group 1: microemulsion cyclosporine with mycophenolate mofetil and steroid (n=53) / group 2: tacrolimus with mycophenolate mofetil and steroid (n=44)), we retrospectively reviewed renal transplant recipients between January 1997 through December 2001 in Dongsan medical center. RESULTS: The biopsy proven acute rejection rate were 30.2% in cyclosporine group, while 20.5% in tacrolimus group. Among the 9 cases of acute rejection in tacrolimus group, four cases were associated with BK virus infection. The response rate of acute rejection to steroid pulse therapy was 75.0% and 66.7% in group 1 and 2 respectively. There were no statistical difference in serial changes of serum creatinine after transplantation, number of recipients whose serum creatinine more than 2.0 mg% and proteinuria more than 100 mg/dL, checked at one year. To treat the side effect and intractable acute rejection, calcineurin inhibitors were exchanged each other in 5 recipients. Average steroid daily dosage at one year was 7.10+/-2.82 mg in cyclosporine group while 5.27+/-1.45 mg in tacrolimus group. Overall graft survival were no significant difference between groups up to 24 months but in recipients who developed acute rejection showed better graft survival in cyclosporine group while recipients without acute rejection had better survival in tacrolimus group. CONCLUSIONS: Tacrolimus based immunosuppression showed lower incidence of acute rejection and better steroid sparing effect but developed more polyoma virus infection which eventually deteriorate graft function and survival up to two years.
