Ruptured cerebral aneurysms operated on with only MRA. Reports of two cases.
Two cases of ruptured aneurysms of anterior communicating artery were reported. The aneuryms were showed only by means of MR angiography and operated on without conventional angiography, since patients' allergy to drugs and medium contrast. The MRA showed precisely the sites of the aneurysm and the directions of the sac, but underestimated the size of the sac. In spite of the lack of angiograms induced a great caution during the dissection of the aneurysm and made necessary a larger operative field, anyway clipping of the aneurysm's neck was performed without great difficulties.
