Ischemic colitis, mesenteric ischemia, gangrenous bowel, rectal bleeding, syncope, hypotension, hypovolemia, electrolyte disorders, suspected sphincter of Oddi spasm, bile duct stone, cholecystitis with elevated transaminases, and hypersensitivity reaction including rash, urticaria, pruritus, and serious allergic type 1 reactions have been reported,... 

Compared with brain ischemia spinal cord strokes are caused by more diverse etiologies. Up-to-now there is no satisfactory and accepted classification of spinal infarcts. Etiologies include circulatory arterial and venous disorders. From a clinical and pathoanatomical point of view it seems reasonable to differentiate between acute ischemic myelomalacia and subacute to chronic vascular myelopathy (Table 17.1). In most cases MRI enables the differentiation of these two main etiologies. A deficient spinal arterial blood flow generally has various causes, ranging from the occlusion of intercostal or lumbar arteries to affection of the intrinsic arteries of the spinal cord. ... 

Anterior ischemic optic neuropathy is a disorder whose pathophysiology is poorly understood. The difference between the intraocular pressure and the perfusion pressure in the posterior ciliary arteries determines the circulation in the optic disc, and a reduction in this difference may contribute to ischemia.
