[Correlations between the type of distribution of the branches of the inferior mesenteric artery and the aspect of the mesocolon]. / Corelatiile dintre tipurile de distributie a colateralelor arterei mezenterice inferioare si aspectul mezoului.

ABSTRACT

Emergence pattern of inferior mesenteric artery (IMA) branches leaded to description of 6 types of arterial distribution, each of them being correlated with a certain mesocolon aspect. The height of mesosigmoid depends on coalescence pattern and grade, and has a particular importance in terminal colic and retroperitoneal viscera's surgery. For each of the 6 types of distribution are described different ways of differential ligatures, for elongation and descending the colon, initially establishing the predominant collateral trunks. For practicing these ligatures we have to take count of preoperative paraclinic investigations, general and particular haemodynamic conditions and some intraoperatory parameters.
