[Distant heart procurement for transplantation]. / Procuración a distancia de corazóncon fines de trasplante.

BACKGROUND: The low availability of organ donors is a serious hindrance to heart transplantation. Long-distance organ procurement has been accepted as an option despite longer ischemic time for the heart. METHODS: Long-distance procurement from outside Mexico City in adult patients with terminal heart failure submitted to orthotopic heart transplantation between February 1st 2011, and January 31st 2012, was assessed. Ischemic time, distance from Mexico City, and perioperative and short-time mortality were determined. RESULTS: There were 14 orthotopic heart transplants during the analyzed period. In 12 cases long-distance heart procurement was required. Mean age of recipients was 42.7 years (range between 17 and 61 years). Seven patients were male and five female. Mean ischemic time was 228.58 minutes. The longest distance of procurement for land and air travel was 2,319 km; and the lowest, 22.5 km. Perioperative mortality was 8.33% (one patient), and there were 2 short-term deaths due to non-cardiac complications. In this series we included a case of heart-kidney transplantation from same donor. CONCLUSION: At our hospital, long-distance procurement for heart transplantation is a useful procedure with good results.

[Experience in liver transplantation (1996-2011) at the UMAE, General Hospital Gaudencio González Garza, National Medical Center La Raza, Mexican Institute of Social Security, Mexico City, D.F]. / Experiencia en trasplante hepático (1996-2011) en la UMAE, Hospital General Gaudencio González Garza, Centro Médico Nacional La Raza, Instituto Mexicano del Seguro Social, México, D.F.

We present the experience of General Hospital CMN La Raza from 1996 to 2011. In this period, we have made 40 liver transplants in adults and 22 pediatric liver transplants. A 100% of adult population received a graft from deceased donor; while in the pediatric age group, 60% were from deceased donor and 40% from living donor. The long-term follow-up is shown only for adult group due to lack of data in the pediatric group. The mean age for the adult group is 42 years old and 4.5 years for the pediatric group. The main indications for liver transplantation in adults were: cirrhosis due to chronic hepatitis C in 47.5% and cirrhosis due to alcohol abuse in 15% of the group. In the pediatric group was more likely the biliary atresia (60%) as an indication for liver transplantation followed by fulminant hepatitis (15%). We show the evolution of the hepatectomy's technique in the adult group: it was initially using conventional technique and later it changed to preservation of cava vein (Piggy Back). In the same way, the reconstruction of the bile-duct was initially made using a T-tube stenting and currently, we use end to end bile-duct reconstruction. The patient's survival at 1, 5, and 10 years was 41.5, 27.2, and 13.6%, respectively; with a median of global survival of 6.2 months. Long-term patient's survival has improved after 2004 compared to previous period.

Autotransfusión en cirugía cardiaca / Autologous blood transfusion in cardiac surgery

Se describe la utilización de transfusión autóloga por depósito previo (TADP) en 75 pacientes con comuniación interauricular o interventricular que requirieron cirugía entre julio de 1992 y septiembre de 1996 en el Centro Médico La Raza. La mayoría correspondió al sexo femenino (93.3 por ciento), la edad promedio fue de 29 años y 64 por ciento perteneció al grupo sanguíneo O factor Rh positivo; 8 por ciento no requirió unidad de TADP, 2.6 por ciento requirió una 2.6 necesitó dos y 86.8 por ciento requirió tres. En 10.6 por ciento se utilizó sangre homóloga adicional. No existieron complicaciones atribuibles a la TADP. El objetivo de evitar la utilización de sangre homóloga se alcanzó en 89.4 por ciento de los casos
