BACKGROUND: This paper attempts to see if simple blood test results can predict the state of an emergency aneurysm as being non-ruptured, contained leak or free rupture. METHODS: Ninety-three patients who presented to our emergency room and were operated for abdominal aortic aneurysm (AAA) between January 1999 and March 2009 were evaluated retrospectively. Cases were classified as: chronic contained rupture (Group I), impending rupture (Group II), dissecting rupture (Group III), and free rupture (Group IV). RESULTS: Chronic contained rupture was determined in 15 (16.1%), impending rupture in 31 (33.3%), dissecting rupture in 14 (15.1%), and true (free) rupture in 27 (29%) cases. Aortocaval fistula was present in 3 (3.2%) patients, aortoenteric fistula in 2 (2.2%) and aorto biliary fistula in 1 (1.1%). Group IV was significantly different from Groups I, II and III with regard to hematocrit levels, white blood cell counts, neutrophils and lymphocyte rates, bicarbonate levels, and mortality rates. CONCLUSION: To avoid a delay in diagnosis, it is important to know the different presentations of emergency AAA. In the emergency room, simple laboratory parameters may be highly directive in suspicion of ruptured AAA.
