Diagnosis of colo-rectal cancer revealed by haemorrhagic complication of intraarterial thrombolysis.

Haemorrhage is a recognized complication of catheter-directed thrombolysis. We report one case of an afore unknown colo-rectal carcinoma, which was detected due to rectal bleeding following intraarterial thrombolysis. As reported with warfarin induced gastrointestinal bleeding complications, patients with unknown tumor developing rectal bleeding after thrombolysis procedure, should receive full diagnostic work-up of the gastrointestinal tract in order to exclude serious but potentially curable disease.
