Summary
CT angiography (CTA) can now identify active bleeding from brain aneurysms. This finding of active aneurysmal hemorrhage on CTA may alter treatment plans and follow-up imaging strategies.
Area of Science:
- Neurology
- Radiology
- Neurosurgery
Background:
- Subarachnoid hemorrhage diagnosis increasingly relies on CT angiography (CTA).
- Identifying active bleeding from intracranial aneurysms is crucial for patient management.
- CT angiogram findings of active aneurysmal hemorrhage are not well-documented.
Observation:
- A case of an actively bleeding anterior communicating artery aneurysm was visualized using CTA.
- The initial CTA revealed contrast extravasation, indicating active hemorrhage.
- A subsequent CT scan confirmed ongoing bleeding and extension into subarachnoid spaces and ventricles.
Findings:
- CT angiography can visualize active aneurysmal hemorrhage.
- Extravasation of contrast on CTA signifies ongoing bleeding.
- Hemorrhage progression can be monitored with serial CT scans.
Implications:
- Recognizing active aneurysmal hemorrhage on CTA can guide immediate treatment decisions.
- CTA findings may influence the necessity and timing of follow-up imaging.
- Early identification of active bleeding can potentially improve patient outcomes in subarachnoid hemorrhage cases.

01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
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...
01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:26Aneurysm III: Interprofessional Care
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...
01:30Aneurysm I: Introduction
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...
