How to embolize wide-necked aneurysms? Two embolization techniques for wide-necked aneurysms
1Department of Neurosurgery, Fukuoka University School of Medicine; Fukuoka, Japan.
Summary
Novel endovascular techniques, including the double Guglielmi detachable coil (GDC) technique and stent-coil combinations, offer safer treatments for wide-necked and fusiform aneurysms. These methods show promise in achieving complete embolization and preventing rebleeding with good patient outcomes.
Area of Science:
- Neurosurgery
- Interventional Radiology
- Vascular Surgery
Background:
- Limitations exist with current Guglielmi detachable coil (GDC) systems for wide-necked aneurysms.
- Novel endovascular approaches are crucial for safer and more definitive aneurysm treatment.
Purpose of the Study:
- To review the usefulness of the double GDC technique (DGT) for wide-necked aneurysms.
- To review the usefulness of stent placement and coil deposition (CTSC) for fusiform aneurysms.
Main Methods:
- The DGT involves scaffolding a GDC coil as a stabilizing frame, reinforcing it with a second coil, and releasing both.
- CTSC involves artery reconstruction with a stent and GDC packing through stent interstices.
Main Results:
- A patient with a wide-necked internal carotid artery aneurysm treated with DGT showed complete embolization at three months with no adverse events.
- A patient with a dissecting fusiform vertebral artery aneurysm treated with CTSC had an uneventful six-month follow-up, with confirmed aneurysm exclusion and good flow.
Conclusions:
- The double GDC technique is effective for wide-necked aneurysms.
- The combination of stent placement and coil deposition is a viable option for fusiform aneurysms, preventing rebleeding.

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...
01:29Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
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...
