Renal oncocytomas account for approximately 5% of renal parenchymal tumors. Usually it has unilateral solitary oncocytic nodule, but bilateral multifocal renal oncocytomasis is rare. The term renal oncocytoma should be used to characterize a well-differentiated renal epithelial tumor with eosinophilic granular cytoplasm that has benign behavior and favourable progress. Also, multiple oncocytoma distributed diffusely in both kidneys is termed renal oncocytomatosis Because of the benign nature, multicentricity, possible bilaterality and absence of pathognomonic radiographic features, renal oncocytomas should be considered in differential diagnosis of solid masses, especially renal cell carcinoma. We report a patient with bilaleral multifocal renal oncocytomatosis, who had progressive renal failure. Renal oncocytomatosis was diagnosed pathologically after bilateral nephrectomy.

BACKGROUND: Pulmonary artery banding (PAB)in the functional univentricular heart (UVH)is a palliative procedure for staging toward the Fontan procedure;however,it is known to be a risk factor. MATERIALS AND METHOD: The records of all 37 patients with functional UVHs who underwent surgical palliation using PAB between September 1989 and August 1999 were reviewed retrospectively.We investigated the aortic arch obstruction,the development and progression of subaortic stenosis after PAB,and risk factor of mortality according to surgical method. RESULT: In 37 neonates and infants with single ventricular physiology,aortic arch obstruction was combined in 7.There were 6 early deaths (16.2%)after PAB and 3 late deaths (8.1%)after Fontan operation.The actuarial overall survival including early mortality at 3 and 5 years were 8 0 .7+/-6.6%,72.2 +/-8.2% respectively. Among 31 patients who survived PAB,27 patients (87.1%)could become candidates for Fontan operation;22 patients(71.0%)completed Fontan operation with 3 deaths and 5 were waiting bidirectional cavopulmonary shunt(BCPS)or Fontan operation (follow-up mean 4.5 year,minimal 2 year). Subaortic stenosis developed in 8 patients after PAB (8/29,27.6%);3 cases in the patients without arch anomaly (3/22,13.6%)and 5 in those with arch anomal y (5/7,71.4%).The subaortic stenosis was managed with Damus-Kaye-Stansel procedure (DKS)in 6 patients without operative mortality and conal septum resection in 2 without long-term survivor. Analysis of risk factors established that aortic arch obstruction was strongly associated with subaortic stenosis (p<0.001).The only risk factor of late mortality was Fontan procedure without staged palliation by BCPS (p=0.001). CONCLUSION: PAB is effective as an initial palliative step in functional UVH.And the high risk group of patients with aortic obstruction can undergo effective short-term PAB as an initial palliative step,with subsequent DKS for subaortic stenosis.This strategy,initial PAB and careful surveillance,and early relief of subaortic stenosis can maintain acceptable anatomy and hemodynamics for later Fontan procedures.

In off-pump coronary artery bypass grafting (CABG), multiple proximal anastomosis may increase the risk of cerebral embolism (air, debris) and aortic injury (dissection, pseudoaneurysm). Radial artery (RA) has no intraluminal valve such as saphenous vein. We applied Cabrol technique using aortic root replacement for proximal anastomosis in off-pump CABG. Cabrol technique using RA graft can reduce numbers of proximal anastomosis and reduce number of aortic manipulation in off-pump CABG. We report a Cabrol technique for proximal anastomosis in off-pump CABG with RA graft.
