Angiologic analysis of abdomino-anal resection variants of the rectum

The angiotensiometry of inferior mesenterial artery, its branches, marginal arterial arch and intramural vessels of the rectum in supposed reduction zone in abdomino-anal resection variants during 66 operations is performed. The occlusion variants all may result in such arterial pressure value when the necrosis develops. The optimal variant of extraorganic vessels ligation may be determined and the resection level of the rectum with adequate intraorganic hemodynamics may be chosen to prevent the ischemic necrosis of the reduced rectum in all cases using angiotensiometry data.
