Summary
Intracranial serpentine aneurysms (SA) are rare. Treatment involves surgery or embolization, but evaluating collateral circulation is crucial. Careful management ensures satisfactory outcomes for most SA patients.
Area of Science:
- Neurology
- Neurosurgery
- Vascular Neurology
Background:
- Intracranial serpentine aneurysms (SA) are rare vascular malformations.
- Limited multi-case studies exist, necessitating literature review for understanding.
Purpose of the Study:
- To review the literature on the formation, natural history, clinical presentation, imaging, and treatment of intracranial SA.
- To provide insights into the management of this rare condition.
Main Methods:
- Comprehensive literature review of PubMed.
- Analysis of case studies focusing on SA characteristics and treatment outcomes.
Main Results:
- Intracranial SA can be treated surgically or via endovascular embolization.
- Pre-treatment evaluation of collateral circulation using tests like the balloon occlusion test (BOT) is essential.
- Direct excision or embolization is feasible with adequate collateral flow; bypass surgery is needed for poor collateral circulation.
- While most patients achieve satisfactory results, aneurysm enlargement can occur post-embolization, and mass effect requires careful consideration.
Conclusions:
- Careful patient selection and treatment planning, including collateral circulation assessment, are key to successful SA management.
- Surgical and endovascular techniques can yield good results, but potential complications like aneurysm enlargement and mass effect must be monitored.

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.

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

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...
