La enfermedad de Takayasu, es una enfermedad crónica, idiopática, inflamatoria que afecta principalmente a grandes vasos. Predomina en mujeres jóvenes cuyos síntomas pueden aparecer entre los 15 y 30 años. Se caracteriza por un infiltrado linfomonocitario y presencia de granulomas que progresan llegando hasta la reducción de la luz, desencadenando fenómenos trombóticos. En orden de frecuencia se pueden afectar las arterias subclavias (85 %), aorta torácica descendente (58 %), abdominal (20 %), vertebral (17 %), ilíaca (16 %), pulmonar (15 %) y coronarias, en menos del 10 %. Presentamos dos casos de localización poco usual y presentación atípica a nivel de vasos femorales, renales ademas de compromiso vascular en una gestante previamente hipertensa.

Introducción: la irrigación arterial del riñón, clásicamente descrita, se produce a partir de la arteria renal y sus dos ramas terminales exclusivamente. El objetivo de la investigación fue determinar la presencia y distribución de las arterias renales polares. Métodos: se realizó un estudio cuantitativo, longitudinal, prospectivo, observacional y descriptivo, en 37 bloques, provenientes de cadáveres sin cirugías aortorenales ni malformaciones congénitas renoureterales demostrables, en el Hospital Provincial Clínico Quirúrgico Docente Celia Sánchez Manduley, de Manzanillo, provincia Granma. Los bloques fueron lavados, fijados y disecados por el método macroscópico directo. Resultados: las arterias polares fueron más frecuente en el sexo masculino y en el lado derecho, demostrándose su presencia en 16 casos (43,24 %), donde 9 presentaban, al menos, una arteria polar superior; 3 presentaron, al menos, una arteria polar inferior; y 4 casos presentaron, al menos, una de cada arteria polar. Predominó el origen de ambas arterias polares como ramo directo de la arteria aorta. Conclusiones: las arterias polares no constituyen variantes anatómicas de rara presencia y su conocimiento es imprescindible en el planeamiento de la cirugía excerética y reconstructiva nefrourológica.

Objetivos. Evaluar el rendimiento diagnóstico de la angiografía renal (ARM) y urografía (URM) por Resonancia Magnética (RM) en potenciales donantes de riñón mediante la correlación con hallazgos quirúrgicos. Materiales y Métodos. Se evaluaron 55 potenciales donantes mediante protocolo angiográfico y urográfico en múltiples fases en un resonador de 1,5 T. La ARM valoró la existencia de variantes anatómicas o alteraciones estructurales arteriales o venosas y la URM valoró el parénquima renal y el sistema colector en fases nefrográfica y excretora. Los resultados fueron comparados con hallazgos quirúrgicos. Resultados. La correlación se realizó en 42 donantes efectivos. En ellos, se observó una especificidad de la ARM del 94% y una exactitud diagnóstica del 93%. Se identificaron variantes anatómicas y alteración estructural arterial en el 29% de los pacientes. La valoración venosa y urográfica de la RM resultó concordante quirúrgicamente en todos los casos. Conclusión. Las imágenes de RM proveen un método seguro y eficaz para la valoración prequirúrgica renal de forma integral en potenciales donantes de riñón.Objectives. To evaluate diagnostic accuracy of renal MRangiography(MRA) and MR- urography (MRU) in the assessment of normal anatomy and renal vascular pathology in potential renal living donors compared with surgical findings. Materials and Methods. Evaluation of 55 potential living donors performing one-step MR angiography and MR urography in a 1.5 T magnet. MRA evaluated the presence of anatomic variants or arterial or venous pathologic conditions. MRU depicted renal parenchyma anatomy and collector system. These results were compared with surgical findings. Results. MRA and MRU findings were actually compared with surgical findings in 42 effective donors. MRA specificity was 94 % and diagnostic accuracy was 93 %. Anatomic variants and arterial structural abnormalities were detected in 29 % of patients. Venous and excretory surgical findings were consistent in 100 % of cases. Conclusion. One-step MRA and MRU constitutes an accurate method for pre-operative assessment of renovascular and excretory anatomy in potential living donors.

Introduction: Knowledge of renal artery's variations is vital when performing surgical procedures, mainly in: renal transplants where such variations may complicate the procedure and jeopardize the viability of the organ; vascular reconstructions; nephrectomies caused by tumors or emergency nephrectomies in renal trauma; for which anatomical knowledge of renal pedicle is necessary to achieve a correct approach and management. Material and methods: Descriptive and observational study. 36 corpses with no aorto-renal surgeries nor renal-ureteral congenital malformations were dissected. Bilateral renal arteries' origin and mouth were analized in the period between January and August 2015. Results: 25 (69.44%) of it had renal arteries single-source and 11 (30.56%) of the corpses presented variations in the number of main renal arteries and the existence of accessory polar arteries. 4 (36.37%) were immediately divided his origin; 4(36.37%) of it presented double renal arteries 2 (18.18%) had one main stem plus a right lower polar artery and another two left main trunk more polar arteries. One case (9.09%) of left triple renal arteries. Conclusión: Anatomical knowledge of renal arteries is necessary for surgical residents to have a proper vascular control. [ABSTRACT FROM AUTHOR]

The knowledge of the arterial variations is very important for the diagnosis and the surgical procedures. The purpose of this study was determine the number and the origin-levels of the renal and superior mesenteric arteries in relation to the vertebral bodies. For this, we used the angiographies of 31 patients, Chileans, adult, of both sexes. The angiographies were obtained by Helicoidal Computed Tomography, in these we localized the origin points of the mentioned arteries. We divided the vertebral bodies in three parts, superior, middle and inferior, considering too the intervertebral disc. In 26 patients, in both sides the renal artery was only; in the right side it was double in 2 patients and in the left side in 3. The right renal artery originated from the level of L1 vertebra in 11 cases; from the level of L1-L2 intervertebral disc in 7; from the level of the L2 vertebra in 10 and from the level of the L2-L3 intervertebral disc in 2. The left renal artery originated from the level of the L1 vertebra in 9 cases; from the level of the L1-L2 intervertebral disc in 6; from the level of the L2 vertebra in 12 and from the level of the L2-L3 intervertebral disc in 2. The superior mesenteric artery was only in all cases; it origin level was always cranial to the renal arteries origin. The origin level of the superior mesenteric artery was observed in relation to the L1 vertebra in 16 cases and to the level of the L2 vertebra in 8. We considered specifical origin levels associated to the vertebral body division. The results of this study will complete the knowledge of these arteries and are a contribution to the surgical anatomy of abdominal region. [ABSTRACT FROM AUTHOR]
