Die kollaterale Gefäßversorgung des linken Hemikolons

Abstract

The low incidence of an additional communication (Riolan's arch) and possible additional impairment of the blood supply should be taken into account during operation.

Novel Visceral-Anastomosis-First Approach in Open Repair of a Ruptured Type 2 Thoracoabdominal Aortic Aneurysm: Causes behind a Mortal Outcome

“…Hypoperfusion of the left colon may have been caused by back-bleeding from segmental arteries causing a steal effect through visceroparietal collaterals [12, 13], by haemodynamic instability towards the end of the operation, and by accidental obstruction of the axillobifemoral graft just proximally to the left groin. Accidental compression of the axillobifemoral graft can be potentially detectable and preventable by femoral pressure or flow monitoring and by the use of externally ring-supported prosthesis [1].…”

Bridging the Gap with an Ileocolonic Graft after Extensive Colorectal Resections

“…However, transection of the MCA potentially puts additional bowel segments at risk and is impossible when there is insufficient arterial collateralization between the ileocolic and middle colic arteries. In addition, even if a normally calibrated MA is seen, atherosclerosis may become relevant, especially in elderly patients when the blood supply of the right colon solely depends on the ileocolic pedicle [20].…”
