The association of abdominal aortic aneurysms with aneurysmal disease of the thoracic aorta is well established. However, rupture of a descending atherosclerotic thoracic aortic aneurysm in association with an infrarenal abdominal aortic aneurysm can present a difficult diagnostic and therapeutic problem to the treating physician. This article presents a case of rupture of an atherosclerotic descending thoracic aortic aneurysm in the face of what clinically appeared to be a leaking or ruptured abdominal aortic aneurysm.

This case is an example of an unsuspected abdominal aortic aneurysm. The patient's symptoms and the history obtained were suggestive of osteoarthritis. The patient sought medical attention for low-back pain through a compensation and pension exam.

We evaluated the safety, pharmacokinetics, and pharmacodynamics of diaspirin cross-linked hemoglobin (DCLHb) solution in patients after repair of abdominal aortic aneurysm. We performed a randomized, single-blind controlled study with 10 patients in the surgical intensive care unit of a tertiary care facility. Within 24 hours after repair of an abdominal aortic aneurysm, each patient received an infusion of DCLHb (50 mg/kg or 35 mL for a 70-kg patient) or an equal volume of hetastarch. Variables were measured before infusion, at 15 and 30 minutes postinfusion, and at hourly intervals up to 72 hours. Compared with controls, the experimental group had significantly greater mean pulmonary artery pressure at 30 minutes (mean +/- SD, 26.4 +/- 3.18 vs. 22.8 +/- 2.86 mm Hg), greater mean arterial pressure through 30 minutes (100.8 +/- 8.67 vs. 81.6 +/- 13.8 mm Hg), and greater plasma hemoglobin through 2 hours (69.3 +/- 6.08 vs. 1.8 +/- 0 g/dL). Cardiac output was significantly less in the DCLHb group at 2 hours (5.34 +/- 7.92 vs. 6.18 +/- 0.54 L/minute), levels of serum bilirubin were significantly less at 24 and 48 hours (94 +/- 0.26 vs. 1.56 +/- 0.73 mg/dL), and platelet counts were significantly greater at 24 hours (128 +/- 35.8 vs. 101 +/- 55.7 mg/dL). The two groups did not differ in oxygen delivery or consumption. One patient treated with DCLHb had a myocardial infarction 36 hours postinfusion. No patient had antibodies to DCLHb. At this dosage, DCLHb was well tolerated without severe organ dysfunction or toxicity. However, its use may lead to decreases in cardiac output because of increases in afterload, which may pose serious problems with left ventricular function.

A patient presented to the emergency department with undifferentiated shock 4 days after discharge from a hospitalization for a lower gastrointestinal bleed. The patient fulfilled 4/4 of the Systemic Inflammatory Response Syndrome criteria and 3/3 of the quick Sequential Organ Failure Assessment criteria on presentation to the emergency department, notably, without a localized source of infection and no localizing symptoms. After admission, the patient's hemoglobin was found to have dropped more than expected after intravenous (IV) fluid administration, suggesting a potential alternative or concurrent etiology of the patient's shock state. A digital rectal and focused assessment with sonography in trauma exam were performed and negative. The patient was then diagnosed with a ruptured infrarenal abdominal aortic aneurysm contained in the retroperitoneum by repeat point-of-care ultrasound. The patient was hemodynamically stabilized and taken for emergent grafting without confirmatory imaging. The patient was later found to also have 4/4 blood cultures positive with methicillin-sensitive Staphylococcus aureus associated with an aortic valvular vegetation and a mycotic aneurysm which contributed to the abdominal aortic aneurysm rupture. This case supports the use of comprehensive point-of-care ultrasound imaging to more rapidly and more definitively differentiate types of shock and etiologies of a shock state which can lead to more timely changes in management and improvement in outcomes.
