Summary
Pituitary dysfunction is frequent following aneurysmal subarachnoid hemorrhage (aSAH). However, this endocrine abnormality does not impact patient outcomes at six to twelve months post-event.
Area of Science:
- Neuroendocrinology
- Neurosurgery
- Critical Care Medicine
Background:
- Pituitary dysfunction following aneurysmal subarachnoid hemorrhage (aSAH) is not well understood.
- The impact of post-aSAH pituitary abnormalities on patient outcomes requires further investigation.
Purpose of the Study:
- To determine the prevalence of pituitary dysfunction after aSAH.
- To assess the effect of pituitary dysfunction on clinical outcomes in aSAH patients.
Main Methods:
- Prospective cohort study of adult aSAH patients admitted to the ICU across three centers.
- Endocrine function testing in the acute (≤48h), subacute (1-3 weeks), and chronic (6-12 months) phases post-aSAH.
- Clinical outcomes assessed at 6-12 months using the modified Rankin Scale.
Main Results:
- Fifty-six patients were included in the study.
- High prevalence of pituitary dysfunction observed: 92.3% acute, 83.3% subacute, and 83.3% chronic phases.
- Pituitary-gonadal axis dysfunction was the most common abnormality; no correlation found between pituitary dysfunction and clinical outcome.
Conclusions:
- Pituitary dysfunction is a common complication after aSAH.
- Post-aSAH pituitary dysfunction does not appear to influence clinical outcomes at 6 to 12 months.

Aneurysm II: Clinical Manifestations and Diagnostic Studies
124
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aneurysm III: Interprofessional Care
163
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Aneurysm I: Introduction
195
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
