Editing Ischaemic colitis (section)

== '''Pathophysiology''' ==

* Disease location
** Tends to be segmental,      mostly splenic area, but rectosigmoid and caecum can be involved
** Can be isolated right-sided      in 25%
*** Worse prognosis, more       likely to need surgery
*** More associated with IHD,       CKD, AF
** Pan-colonic IC has bad      prognosis
* Schein says to differentiate     between those comorbid (IHD, smoking, CKD) patients who get 'spontaneous'     ischaemic colitis, and those who get it secondary to systemic     hypoperfusion from another cause. However, isn't this the same end result,     and wouldn't the former predispose to the latter, and wouldn't they be     treated the same? So not a clinically significant difference.
