Role of imaging in the evaluation of vascular complications after liver transplantation.

Clinical manifestations of liver transplantation complications can be subtle and non-specific. Medical imaging, mainly Doppler ultrasound, plays an important role to detect and grade these. Colour Doppler ultrasound exams are routinely performed at 24-48 h, on the 7th day, the first and third month after transplantation. MDCT and MR images are acquired based on the Doppler ultrasound (DUS) findings, even in the absence of abnormal liver function. As vascular complications appear early after surgery, DUS should be performed by experience personnel. Diagnostic angiography is seldom performed. This pictorial review illustrates the key imaging findings of vascular complications in patients with liver transplantation: hepatic artery complications (such as thrombosis, stenosis of the anastomosis and pseudoaneurysms), portal vein abnormalities (such as occlusion and stenosis) and hepatic veins and/or inferior vena cava flow changes (Budd-Chiari syndrome).

ALPPS monosegmento: una nueva variante de las técnicas de regeneración hepática rápida. Revisión crítica de los resultados iniciales de nuestra serie / Monosegment ALPPS: A new variant of the techniques for rapid hepatic regeneration. Critical review of the initial results of our series

La hepatectomía secuencial, descrita en la literatura anglosajona con el acrónimo ALPPS (Associating Liver Partition and Portal vein ligation for Staged hepatectomy) es una técnica novedosa que ofrece un crecimiento rápido y efectivo del volumen remanente hepático, y que permite la resección quirúrgica de lesiones hepáticas consideradas inicialmente irresecables. Los resultados a corto y largo plazo y la conveniencia de realizar esta técnica son cuestiones que permanecen en discusión a la espera de los resultados finales de los registros multicéntricos. El objetivo del presente trabajo es la revisión crítica de los resultados de la serie de casos realizados en nuestro centro (n = 8). Por otra parte, es posible con esta técnica dejar un único segmento hepático como remanente y realizamos una descripción de esta variante técnica novedosa (ALPPS monosegmento), llevada a cabo en uno de los casos

Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) is a novel surgical technique that provides fast and effective growth of liver remnant volume, allowing surgical resection of hepatic lesions initially considered unresectable. Short and long-term results and the convenience of carrying out this technique are issues that still remain under debate while waiting for the final outcomes of the multicenter registries with larger number of cases. The aim of this paper is to describe, from a critical point of view, the outcomes of the cases performed at our center (n = 8). On the other hand, it is possible to leave only one hepatic segment as a liver remnant and we illustrate this new surgical procedure (ALPPS monosegment) performed in one patient
