## Overview Strongylus vulgaris larvae migrate through the cranial mesenteric artery, causing arteritis, thrombus formation, and potentially thromboembolic colic from intestinal infarction. Clinical signs include recurrent colic, weight loss, intermittent fever, and diarrhea. Widespread use of modern dewormers has made clinical disease uncommon, but arterial lesions are still found in some populations. ## Causes Migration of Strongylus vulgaris fourth-stage larvae. ## Diagnosis Clinical signs, history of inadequate deworming, and sometimes ultrasound or surgical findings. Definitive diagnosis is often at necropsy. ## Treatment Anthelmintics and supportive care for colic. Infarcted bowel requires surgery. ## Recovery and Prognosis Variable. Acute infarction has a poor outlook. ## Prevention Regular strategic deworming that includes larvicidal activity against Strongylus vulgaris.
