Atheroembolic involvement of renal allografts.

Renal atheroembolism is a well-recognized cause of renal insufficiency. Two renal allograft recipients with cholesterol atheroemboli in their allograft biopsies are described. In one patient, the origin of the atheroemboli was the recipient aorta while in the second patient the source was the donor.

Transplantation of multiple abdominal viscera.

Two children with the short-gut syndrome and secondary liver failure were treated with evisceration and transplantation en bloc of the stomach, small intestine, colon, pancreas, and liver. The first patient died perioperatively, but the second lived for more than 6 months before dying of an Epstein-Barr virus-associated lymphoproliferative disorder that caused biliary obstruction and lethal sepsis. There was never evidence of graft rejection or of graft-vs-host disease in the long-surviving child.

Transplantation of the liver for metastatic endocrine tumors of the intestine and pancreas.

In the Pittsburgh series of 1,000 orthotopic liver transplants (OLTx), from January 1981 to July 1987, the indication for transplantation in five patients consisted of unresectable hepatic metastases arising from endocrine tumors of gastrointestinal origin: glucagonoma, two patients; carcinoid, two, and gastrinoma, one patient. Three patients underwent resection of the primary tumor (two distal pancreatectomies and one ileal resection) at the time of the hepatic transplantation. All patients underwent extensive nodal dissection.

Liver transplantation: an unfinished product.

Liver transplantation has become an extraordinarily valuable and useful operation, but one that is not perfect and that has not been exploited to anything like its full potential. Better immunosuppression may become available soon as exemplified by developments with the Japanese drug, FK506. Improved preservation with the UW solution is already here.

Evidence for hyperacute rejection of human liver grafts: The case of the canary kidneys.

Sequential liver and kidney transplantation from the same donor was performed in 2 patients. The kidney in Patient 1, which was transplanted after the liver, was hyperacutely rejected and removed 6 hours later. The first liver as well as another liver transplanted 3 days later developed widespread hemorrhagic necrosis.

Hepatic artery thrombosis following pediatric liver transplantation: Assessment of blood flow measurement in allografts.

The purpose of this study was to define parameters which could be predictive of hepatic artery thrombosis, which continues to be a major complicating factor in pediatric liver transplantation. The hepatic blood flow of 14 pediatric liver patients (15 grafts) who weighed less than 15 kg was measured electromagnetically during orthotopic liver transplantation. The results of blood flow determination and the clinical data in 7 patients (8 grafts) who developed hepatic artery thrombosis were compared with those of 7 control patients.

Infection with human immunodeficiency virus in the Pittsburgh transplant population. A study of 583 donors and 1043 recipients, 1981-1986.

We performed a retrospective serologic survey of 583 organ donors and 1043 transplant recipients for antibodies to human immunodeficiency virus type 1 (HIV-1). Two (0.34%) of the 583 donors and 18 (1.

The University of Pittsburgh: a three and three-quarter-year experience with cadaveric renal transplantation under the point system.

Eight hundred and sixty kidney transplants were performed at the University of Pittsburgh over a 3.75-year period between January 1, 1986 and October 19, 1989. Recipient selection was by means of a computerized point system designed to allocate organs equitably.

Treatment of hepatic epithelioid hemangioendothelioma with liver transplantation.

Ten patients received liver transplants for unresectable epithelioid hemangioendothelioma (EHE). At the time of transplantation, four patients had microscopic metastases to the hilar lymph nodes, and one of the four also had metastases to a rib. The fifth patient had metastases to the lung, pleura, and diaphragm.

Orthotopic liver transplantation for alcoholic cirrhosis.

Fifteen patients with Laennec's cirrhosis underwent orthotopic liver transplantation between 1963 and the end of 1979. The first eight patients died perioperatively or within two months, but four of the next seven patients had long survival; three are still alive after 11 to 14 years. After the introduction of cyclosporine therapy, 41 more patients with alcoholic cirrhosis were treated with liver transplantation from 1980 to June 1987.

Liver transplantation in the treatment of bleeding esophageal varices.

From March 1980 to July 1987, 1000 patients with various end-stage liver diseases received orthotopic liver transplants. Of the 1000 patients, three hundred two had definite histories of bleeding from esophageal varices before transplantation. There were 287 patients with nonalcoholic liver diseases and 15 patients with alcoholic cirrhosis.

Antibody-mediated rejection of human orthotopic liver allografts. A study of liver transplantation across ABO blood group barriers.

A clinicopathologic analysis of liver transplantation across major ABO blood group barriers was carried out 1) to determine if antibody-mediated (humoral) rejection was a cause of graft failure and if humoral rejection can be identified, 2) to propose criteria for establishing the diagnosis, and 3) to describe the clinical and pathological features of humoral rejection. A total of 51 (24 primary) ABO-incompatible (ABO-I) liver grafts were transplanted into 49 recipients. There was a 46% graft failure rate during the first 30 days for primary ABO-I grafts compared with an 11% graft failure rate for primary ABO compatible (ABO-C), crossmatch negative, age, sex and priority-matched control patients (P less than 0.

Aplastic anemia complicating orthotopic liver transplantation for non-A, non-B hepatitis.

Aplastic anemia developed in 9 of 32 patients (28 percent) undergoing orthotopic liver transplantation for acute non-A, non-B hepatitis, at one to seven weeks after the procedure. No patient previously had evidence of hematologic dysfunction or conditions known to be associated with aplastic anemia. No other cases of aplastic anemia were identified among 1463 patients undergoing liver transplantation for all other indications at the four centers participating in the study (chi-square = 415, P less than 0.

Future aspects of renal transplantation.

New and exciting advances in renal transplantation are continuously being made, and the horizons for organ transplantation are bright and open. This article reviews only a few of the newer advances that will allow renal transplantation to become even more widespread and successful. The important and exciting implications for extrarenal organ transplantation are immediately evident.

Renal artery reconstruction for harvesting injuries in kidney transplantation with particular reference to the use of vascular allografts.

At the University of Pittsburgh during the calendar year 1986, an arterial injury occurred during harvesting in 20 (7.5%) of the 270 grafts used to perform kidney transplantation (KTx). Four cases required reconstruction, using extension iliac arterial allografts from cadaveric donors of the same blood type; 6 patients, remodelling of the aortic patch in multiple arteries; 4 cases, repairs for injuries to the smaller segmental/polar arteries; 6 cases, a combination of the above techniques.

The hepatic artery in orthotopic liver transplantation.

Hepatic artery thrombosis (HAT) is a dreadful complication of orthotopic liver transplantation (OLT). This complication occurred in 27 grafts (68% = 27/393 grafts) in 25 patients (9% = 25/313 patients). HAT was responsible for a high mortality (64% = 16/25 patients) despite a high retransplantation rate (70% = 19/27 grafts).
