Preservation of the recipient inferior vena cava in liver transplantation.

Twenty piggy-back (PB) liver transplantations (LT) were compared with 20 LT performed by the standard technique in order to evaluate whether or not the theoretical haemodynamic advantages of the preservation of the inferior vena cava (IVC) have any impact on the final results of the LT. Statistically significant differences were observed in the duration of the hepatectomy, which was longer for PB LT (192 min vs. 146 min), and in the duration of the anhepatic phase, which was shorter in that group (52 min vs. 76 min). There were no differences in the duration of the complete surgical procedure, consumption of blood products, incidence of postoperative acute renal failure, number of reoperations or survival.

[The pediatric liver transplant. The surgical aspects].

The Liver Transplant Program was begun at "La Paz" Children's Hospital on January 1986 after a long period of experimental activities. This was the first experience in the Madrid Community. From January 1986 to June 1989 we made 32 orthotopic liver transplants in 25 patients, seven received a second graft and one them received a liver segment because the donor had a large liver. 114 patients were evaluated but only 84 were considered candidates for liver transplantation. The different diseases of the transplants were: biliary atresia (9), Alagille syndrome (4), deficit alpha 1-antitrypsin (3), autoimmune hepatitis (2), neonatal hepatitis (1), Byler disease (1), Wolman disease (1). absent bile ducts (1), Wilson disease (1). Surgical technique was the same that has been described by Starzl using Eurocollins and lactate Ringer. In the 100% we made multiorgan procurement, liver and kidneys, 7% with heart and two heart-lung with hypothermia. In one occasion the donor operation was done out of the country (RFA--Düsseldorf). We never used by-pass during anhepatic phase. Arterial reconstruction was done by end-to-end anastomosis and in five patients we used aortic graft. Our arterial thrombosis rate was 18%. In one patient the portal vein was atrophic and we used a femoral graft between superior mesenteric vein and donor portal vein. For biliary reconstruction we used Roux-en-Y with intraluminal stent in 18 cases and choledocho-choledochus anastomosis in seven cases. Four patients had biliary complications: two biliary fistulas secondary to arterial thrombosis, biliary stenosis and bowel perforation by the intraluminal stent.(ABSTRACT TRUNCATED AT 250 WORDS)

[Hemoperitoneum secondary to acute cholecystitis in kidney transplant].

We present two cases of acute cholecystitis occurring more than two years after renal transplantation. The course of the acute event was complicated by the presence of hemobilia in one of the patients and severe hemoperitoneum in both patients. We comment the possible etiologic factors, the high efficiency of the diagnostic procedures and the importance of prompt cholecystectomy as the best treatment method.

[Aspects related to extraction and preservation in 60 cases of liver transplant].

Extraction and preservation are of special interest in any liver transplant program. The viability and correct early function of the graft are determinant factors of the success or failure of the transplant. Application of a restrictive criterion in the acceptance of donor livers has allowed us to achieve an optimal viability (96.7%) in our first 60 cases of liver transplant.

Special operative events in the first case of liver grafting after heart transplantation.

Combined heart-liver transplantation is the only therapeutic possibility for patients with familial hypercholesterolemia IIa. A 12-year-old boy with this metabolopathy underwent a double transplant in two steps (different donors). This original alternative was chosen to assure a safer procedure in this critical situation. Details of intraoperative events are described. Cholesterol and LDL decreased to physiologic levels after liver transplantation. The child's condition is optimal 1.5 years after surgery.
