RESUMEN
Realizar un estudio anatómico in vivo con la especial y pequeña disección quirúrgica durante una colecistectomía laparoscópica sobre las variaciones de la arteria cística. Estudio prospectivo de 38 meses, en 2000 pacientes consecutivos sometidos a colecistectomía laparoscópica programada, sin signos de inflamación aguda, ni alteración que impida disección y correcta evaluación del triángulo hepatocístico. Se disecó quirúrgicamente identificándose la arteria cística y posible duplicación, eran clínicamente importantes aquellas con diámetro mayor a 1,5 mm, requerían maniobra hemostática. Se anotaron los hallazgos en planilla especial a los fines del presente estudio. En 1831 casos había arteria única en medio del triángulo hepatocístico. Hubo 169 variaciones (8,45 %). En 97 casos doble vascularización, con una arteria en situación normal y otra ubicada lateralmente al triangulo hepatocístico. En 44 pacientes había una arteria única lateralmente al conducto cístico que no lo cruzaba nunca. En 22 casos existía una arteria cruzando el colédoco y el cístico entrando en el triángulo. En 6 oportunidades una doble arteria, una en el triángulo hepatocístico y otra lateralmente que no cruzaba el cístico ni colédoco. En una oportunidad se observó una sola arteria importante que salía directamente de la placa cística entre segmento 4 y 5, y en otro caso solo pequeñas arterias proveniente de la placa cística. Podemos dividirlas en arterias únicas o dobles, en base exclusiva a la necesidad de maniobra hemostática. Podemos decir que las variaciones estarán presentes en aproximadamente 1/12 casos y necesitará una maniobra hemostática especial en 1/20 casos.
ABSTRACT
This is an anatomical study with the special and small dissection of a laparoscopic cholecystectomy on the surgically important variations of the cystic artery. A prospective, 19-month study was conducted in 2000, including consecutive patients undergoing programmed laparoscopic cholecystectomy, without signs of acute inflammation, or alteration, that would prevent dissection and correct evaluation of the cystohepatic triangle. It was surgically dissected, identifying the main cystic artery and its possible collateral arteries. Those with a diameter greater than 1.5 mm being considered as clinically important, requiring haemostatic maneuver (clipping and / or electrocoagulation). The findings were recorded on a special form for the purposes of this study. The classic, single-artery arrangement in the middle of the cystohepatic triangle was found in 1831 cases. The variations found were 169 (8.45 %). In 97 cases there was double vascularization, with one artery in normal position and another outside the cystic duct. In 44 patients, a single artery that did not cross the cystic was observed. In 22 cases an artery outside the cystic but crossing it before the duct. In 6 cases a double artery, one in the cystohepatic triangle and another outside the triangle, did not cross the cystic or the bile duct. In one instance, a single major artery was seen emerging directly from the cystic plaque between segments four and five. These can be divided into single or double arteries, based exclusively on the need for hemostatic maneuver. Knowledge of anatomical variations of the cystic artery is important for the surgeon. The variation presents in 1 of 12 cases, and requires a special hemostatic maneuver in 1 of 20 cases.
