Summary
Coil embolization for intracranial aneurysms can be lengthy, with supportive devices, procedural morbidity, and large aneurysm size predicting longer procedure times. Most coiling procedures are completed within one to two hours with optimal logistics.
Area of Science:
- Neurosurgery
- Interventional Radiology
- Vascular Neurology
Background:
- The shift from surgical clipping to endovascular coiling for intracranial aneurysms has altered procedural logistics.
- Procedural duration for coiling varies significantly due to multiple influencing factors.
Purpose of the Study:
- To assess the procedural time for endovascular coiling of intracranial aneurysms.
- To identify independent predictors associated with prolonged coiling procedure duration.
Main Methods:
- Procedural time was measured from the first to the last angiographic run post-embolization.
- A long procedural time was defined as the upper quartile (70-158 minutes).
- Logistic regression analysis was employed to identify predictors of extended procedural duration.
Main Results:
- The mean procedural time was 57.3 minutes (median 52 minutes).
- Independent predictors for long procedural time included supportive device use (OR 5.4), procedural morbidity (OR 4.5), and large aneurysm size (OR 3.0).
- Aneurysm location, rupture status, gender, and clinical condition did not significantly predict longer procedure times.
Conclusions:
- Coiling of most intracranial aneurysms can be efficiently managed within one to two hours, encompassing pre- and post-procedural patient care.
- Optimizing logistics is key to achieving predictable and efficient endovascular coiling outcomes.

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...

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...
