Neutrophil-to-Lymphocyte Ratio: A Comparative Study of Rupture to Nonruptured Infrarenal Abdominal Aortic Aneurysm.

Background: Neutrophil-to-lymphocyte ratio (NLR) has recently emerged as a useful predictor of cardiovascular risk and adverse outcomes. According to previous studies, an NLR >5 has the highest sensitivity and specificity for postoperative morbidity and mortality in cardiovascular disease. This study aims to evaluate the NLR in cases of infrarenal unruptured abdominal aortic aneurysm (uAAA) and ruptured abdominal aortic aneurysm (rAAA) and to assess the role of NLR as a prognostic marker of 30-day mortality in patients with uAAA and rAAA who underwent surgical repair.

Giant Infrarenal Aortic Aneurysm Rupture Preceded by Left Lower Limb Motor Deficit.

This report presents the surgical repair and postsurgical outcomes following a ruptured infrarenal aortic aneurysm with a maximum transverse diameter of 20 cm. Its association with acute lower limb motor deficit is rare. Open surgery of giant abdominal aortic aneurysms is often the only available treatment, favored over an endovascular approach in the presence of increased aneurysm size with dislodged abdominal organs, adhesions, and short and angled proximal infrarenal aortic neck, presenting significant additional surgical and anesthesiological challenges.
