Summary
Micrus 3D microcoils effectively serve as initial devices for treating wide-necked aneurysms, ensuring stable neck protection. This approach reduced technical failures in endovascular procedures.
Area of Science:
- Neurosurgery
- Interventional Radiology
- Medical Devices
Background:
- Wide-necked aneurysms pose treatment challenges.
- Secure coil placement is crucial for effective aneurysm occlusion.
Purpose of the Study:
- To evaluate Micrus 3D microcoils as primary devices for wide-necked saccular aneurysms.
- To assess the stability and compatibility of Micrus 3D microcoils during endovascular procedures.
Main Methods:
- Retrospective analysis of 22 wide-necked aneurysms treated with Micrus 3D microcoils.
- Calculation of sac diameter to neck width ratio (near unity).
- Endovascular coiling using Micrus 3D (Spherical) as first coils, followed by GDC or other Micrus coils.
Main Results:
- Micrus 3D microcoils demonstrated stability during placement and detachment.
- Coils were compatible with other embolic agents used for aneurysm filling.
- Procedures were successfully completed in 20 out of 22 aneurysms.
- Aneurysm bleeding in two cases was successfully managed.
Conclusions:
- Micrus 3D microcoils are suitable as initial devices for wide-necked saccular aneurysms.
- Their use enhances stable neck protection and reduces technical failure rates.
- This technique offers a reliable option for complex aneurysm treatment.

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...
01:22Aneurysm IV: Nursing Management
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...
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...

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...
