Rare Case of Left Colic Flexure is Supplied by a Branch from Splenic Artery - a Case Report

脾動脈分支供應結腸左曲(脾曲)之變異 ─ 病例報告

摘要


在本例中發現一條脾動脈的分支,在從脾動脈發自腹腔動脈起源之不遠處發出後,向下外側斜行到達橫結腸與降結腸的交接處,即結腸左曲(脾曲)。結腸左曲在胚胎發育時乃源自後腸,一般是由下腸繫膜動脈分之左結腸動脈負責供應血液。本例中變異之動脈發源自供應前腸之脾動脈,再跨越了胚胎中腸部份,而供應原屬於後腸發育出之結腸左曲,實為一種罕見的變異狀況。

A variation of a branch of the splenic artery was reported in a Taiwanese male cadaver during dissection in 1999. This artery arose from the splenic artery and ran inferiolaterally to the area of the left colic flexure. Since left colic flexure is a segment of embryonic hindgut and the splenic artery typically supplies the foregut, the condition in which an artery of foregut crosses midgut to supply an area of the hindgut becomes interesting.
