Arteriography in ponies with Strongylus vulgaris arteritis.
Abstract: Radiographs of the aorta and abdominal arteries were obtained from a normal anesthetized pony following catheterization of a femoral artery for nonselective, semiselective or selective arteriography. The arteries had smooth borders and regular diameters and the branches of the cranial mesenteric artery could be followed distally on the angiogram through to the smaller branches proximal to the bowel wall. Following arteriography, the pony walked normally and there were minimal alterations of the levels of serum muscle enzymes and blood lactate. The procedures for arteriography were repeated in three days. At that time the femoral artery was patent and satisfactory angiograms were obtained. Similiarly, radiographs were obtained from two ponies artificially infected with Strongylus vulgaris. The cranial msenteric artery and some of its branches, the right renal artery and segments of the aorta had irregular borders and were enlarged. Branches of the cranial mesenteric artery could not be followed distally because the flow of the contrast material was blocked. Following the above procedures, euthanasia of all ponies was expedited and the findings of arteritis, thrombosis and dilatation of arteries at necropsy compared favorably with interpretations from the radiographs. At least in the pony, arteriography can be a valuable research and diagnostic tool for the demonstration of lesions associated with verminous arteritis.

The study examines the use of arteriography as a diagnostic tool in ponies for identifying lesions associated with verminous arteritis caused by the Strongylus vulgaris parasite.
Study Overview
- The study used a healthy anesthetized pony to lay the baseline results for radiographs of the aorta and abdominal arteries. These were obtained after catheterization of a femoral artery using nonselective, semi-selective, or selective arteriography.
- The radiographs showed smooth borders and regular diameters, with arteries and their branches observable up to the smaller branches near the bowel wall.
- The pony exhibited normal behavior post-experiment and showed minimal changes in serum muscle enzymes and blood lactate levels, indicating that the procedure was relatively risk-free.
- The procedures were repeated three days later and produced satisfactory results, with visible, unmuted angiograms confirming the patency of the femoral artery.
Strongylus vulgaris Infection Experiment
- The same procedures were conducted on two ponies that had been artificially infected with Strongylus vulgaris.
- The aorta, certain branches of the cranial mesenteric artery, and the right renal artery showed irregular borders and enlargement.
- In contrast to the healthy pony, the cranial mesenteric artery branches were not fully traceable in the angiogram due to blockage of the contrast material flow – pointing towards an obstructive effect of the infection.
Post-Procedure Euthanasia and Necropsy
- All ponies were euthanized after the procedures, and a necropsy was performed to further investigate the vascular changes.
- The post-mortem findings of arteritis, thrombosis, and arterial dilatation agreed with the radiographic interpretations – suggesting that arteriography is a reliable method for observing these vascular modifications.
Conclusion
- The study concludes that arteriography can serve as a valuable research and diagnostic tool in the case of verminous arteritis, at least in ponies infected with Strongylus vulgaris.
