==== Verminous endarteritis ====
*Caused by larvae of [[Strongylus vulgaris|''S. vulgaris'']] within the cranial mesenteric artery
*Also called "verminous aneurism" (misnomer as aneurism = dilatation/thinning of blood vessel wall; also, aneurisms are rare)
*Wall of artery grossly thickened (organising thrombi, inflammatory responses)
*Can be detected on rectal palpation
*Many cases asymptomatic
*May get embolism → infarction of areas of intestinal wall → colic or chronic ulceration (note: generally good collateral circulation; therefore colic is not inevitable)
*Aberrant larvae may cause thrombosis in other arteries; e.g. iliac, cerebral, coronary
*Avermectin/milbemycins or fenbendazole are used to control migrating ''S. vulgaris'' larvae
