    Anastomoses vasculares no transplante renal pediátrico e uma nova estratégia para anastomoses em crianças de baixo peso

    Introduction: The technical aspects of renal transplantation (RT) performed in children should be specific, particularly with regard to vascular anastomoses (VA) in those that are lower-weight. Objectives: To assess the main VA options in paediatric renal transplantations and propose a new strategy for renal artery trajectory when using the aorta (Ao) and the inferior vena cava (iVC) on the right side. Methods: Data were obtained through a retrospective review of medical records. The sample was represented by 81 patients consecutively undergoing transplantation at Hospital Samaritano in the city of São Paulo, who were classified into two groups: Group 1 (G1) consisted of children under 16 kg, and Group 2 (G2) with children weighing 16 kg or more. Results: The smaller children (G1) received the graft predominantly on Ao and iVC (63%), while the options used for VA varied in children weighing 16 kg or more (G2), predominanting the anastomoses on the common iliac vessels (46%). In the first group, when the Ao was the selected vessel for anastomosis on the right side, the trajectory adopted for the transplanted kidney artery was posterior to the iVC. No vascular complications related to the surgical technique were observed. Conclusions: The Ao and the iVC were the main options for the VA in G1, while the common iliac artery and vein were commonly used in G2. The trajectory for the renal artery posterior to the iVC is feasible and can eliminate one of the possibilities of compression of this vein, and also allows the reconstitution of the usual anatomical pathway of the renal artery on the right side.

    Vascular anastomosis for paediatric renal transplantation and new strategy in lowweight children
    (Wiley-Blackwell, 2014-06-01) Gomes, Adriano Luis; Nogueira, Paulo Cesar Koch [UNIFESP]; Carvalho de Camargo, Maria Fernanda; Feltran, Luciana de Santis; Baptista-Silva, José Carlos Costa [UNIFESP]; Hosp Samaritano; Universidade Federal de São Paulo (UNIFESP); Hosp Rim & Hipertensao
    The technical aspects of RT in low-weight children should be specific, particularly with regard to VA. This retrospective study assesses the main VA options in paediatric RTs and proposes a new strategy for renal artery trajectory when using the Ao and the right iVC. the sample included 81 patients and was categorized into a group of children weighing <16kg and the other group of children weighing 16kg or more. the smaller children received the graft predominantly on the Ao and iVC (63%); however, the VA options varied in children weighing more than 16kg, with anastomoses predominantly to the common iliac vessels (46%). in the first group, when the Ao was the selected vessel for anastomosis on the right side, the trajectory adopted for the transplanted kidney artery was posterior to the iVC. This strategy may reduce the risk of compression of the iVC by the renal artery of the donor kidney and may reconstitute the normal anatomy of the renal artery. Moreover, it did not represent a risk factor for graft loss in this sample.
