Analysis of data on 170 consecutive patients transplanted with kidneys from living relatives.

Graft survival, mortality, histocompatibility and rehabilitation were studied in 170 consecutive patients receiving kidneys from living relatives. Average follow-up was 5 years and one month with a minimum post-transplant evaluation of 6 months. Overall patient survival was 93 per cent at one year and there was a remarkable decline thereafter. Overall graft survival was 84 per cent at one year, 73 per cent at three, and 67 per cent at five years. Among the 76 patients treated since 1979, both patients and graft survival have improved: 93 per cent and 80 per cent at three years, respectively, because of a decrease in serious complications. Although no correlation was found between HLA-A and B loci matching and graft survival in patients with no mismatch in the HLA-DR locus, there was a significantly higher graft survival. Infection, the leading cause of death especially in the early post-transplant period, has been brought under control. Aseptic necrosis of the femoral head which occurred in 27 (16 per cent) patients proved to be the most difficult problem. The majority of patients are functioning well socially and vocationally and reproductive functions have been restored. Transplantation offers a better quality of life for patients with chronic renal failure, as compared to hemodialysis. The increased procurement of cadaver kidneys must be given attention.

New assist method for orthotopic heart transplantation in the dog.

We used cross circulation as an assist method for orthotopic heart transplantation in eight dogs. Seven of the eight dogs could be extubated on the first to third postoperative day and were able to eat and walk several hours after extubation. The survival times and the causes of death in these eight dogs were as follows: 436 days (alive), 5 days (sudden death), 17 days (rejection), 17 days (pyothorax), 3 days (accidental death), 59 days (rejection), 19 days (pneumothorax), and 188 days (alive). None of the dogs died of any problems related to the use of cross circulation. Hematologic and biochemical studies revealed that the CK, CK-MB, LDH, GOT, GPT, and lactate levels increased shortly after the operation and returned to the preoperative values within 14 days. The blood urea nitrogen, creatinine, amylase, hematocrit, and total protein levels remained almost unchanged. No free hemoglobin was detected. These findings indicated that no severe damage occurred to the recipient's organs. The key factors for performing successful cross circulation are as follows: (1) The body weight of the support dog should be at least three times that of the recipient. (2) The systolic pressure of the support dog and the pressure gradient between the support and the recipient should be kept above 150 mm Hg and 50 mm Hg, respectively. (3) The flow rate in the arterial tube should be maintained at between 30% and 50% of the basal cardiac output of the recipient. In conclusion, cross circulation is a suitable assist method for orthotopic heart transplantation in the dog.
