Summary
Angiography effectively diagnoses strangulation intestinal obstruction by revealing organic signs. Functional changes, like slowed blood flow in the mesentery, indicate various intestinal obstructions.
Area of Science:
- Veterinary Medicine
- Diagnostic Imaging
- Gastroenterology
Background:
- Acute intestinal obstruction is a critical condition requiring prompt diagnosis.
- Angiography offers potential for visualizing vascular changes associated with intestinal obstruction.
Purpose of the Study:
- To evaluate the diagnostic utility of angiography in different types of acute intestinal obstruction.
- To identify specific angiographic signs for strangulation, obturation, and paralytic intestinal obstruction.
Main Methods:
- Experimental study involving 76 dogs.
- Induction of various forms of acute intestinal obstruction (strangulation, obturation, paralytic).
- Performance of diagnostic angiography to assess mesenteric and intestinal vasculature.
Main Results:
- Angiographic findings indicative of organic origin were predominantly observed in strangulation obstruction.
- Functional angiographic signs, including reduced arterial and venous blood flow velocity in the mesentery, were consistently present across all obstruction types.
- These functional changes highlight disruptions in mesenteric hemocirculation.
Conclusions:
- Angiography can differentiate organic causes of intestinal obstruction, particularly strangulation.
- Functional hemodynamic changes visualized via angiography are common indicators of mesenteric circulatory compromise in all forms of acute intestinal obstruction.
- Angiography provides valuable insights into the vascular status of the intestines during obstruction.
