Aneurysm III: Interprofessional Care

Aneurysm 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...

Hemorrhagic Stroke l: Introduction

Hemorrhagic 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...

Aneurysm 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...

Aneurysm I: Introduction

Aneurysm 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...

Hemorrhagic Stroke ll: Pathophysiology

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

Summary

Giant aneurysms (GAs) over 25 mm are rare. Fusiform GAs, a rare subtype, have a better prognosis than saccular GAs, especially when presenting with mass effect.

Background:

Giant aneurysms (GAs) are defined as intracranial aneurysms exceeding 25 mm in diameter, accounting for 3-5% of all aneurysms.
GAs are classified into saccular and fusiform types, with fusiform aneurysms being exceptionally rare, comprising only 1% of all intracranial aneurysms.
Fusiform GAs commonly affect the internal carotid artery (ICA), basilar, or vertebral arteries and rarely present with rupture.

Observation:

Treatment for unruptured giant aneurysms remains a subject of debate.
Fusiform GAs, particularly those causing mass effect, demonstrate a more favorable prognosis compared to saccular GAs.
Saccular GAs are associated with an 80% mortality rate within a few years of diagnosis.

Findings:

This manuscript reviews the literature on infrequently encountered intracranial fusiform giant aneurysms.
The discussion highlights the distinct characteristics and clinical behavior of fusiform GAs.

Implications:

Understanding the better prognosis of fusiform GAs, especially with mass effect, can guide clinical management strategies.
Further research into the optimal treatment of these rare aneurysms is warranted.
This review contributes to the knowledge base for managing complex cerebrovascular conditions.
