Severe anaphylactic reaction after blue dye injection for sentinel lymph node biopsy in breast surgery: Report of two cases and literature review.

Anaphylactic reactions, and especially the severe ones (types III and IV), should be kept in mind as considerable adverse effects while using blue dyes for SLNB.

The validity of current vascular imaging methods in the evaluation of aortic anastomotic aneurysms developing after abdominal aortic aneurysm repair.

The aim of this cross-sectional study was to evaluate the validity of current imaging methods for diagnosing anastomotic false aneurysms (AFA) of the aorta. One hundred four patients who had undergone elective abdominal aortic aneurysm repair between January 1, 1985, and May 31, 1991, were studied. All of them were investigated for potential development of an aortic anastomotic aneurysm by B-mode ultrasonography, CT scanning, digital subtraction arteriography, and MRI.
