Summary
The LVIS Jr stent-assisted coiling technique is technically feasible for complex aneurysms. This single microcatheter approach shows good early to mid-term radiographic and clinical outcomes, with a low retreatment rate.
Area of Science:
- Neurosurgery
- Interventional Neuroradiology
- Vascular Neurology
Background:
- The LVIS Jr device offers advantages but presents technical challenges, particularly for complex multistent constructs.
- Y-stent-assisted coiling with the LVIS Jr requires evaluation for feasibility and outcomes.
Purpose of the Study:
- To assess the technical feasibility and early to mid-term outcomes of Y-stent-assisted coiling using the LVIS Jr device with a simple, single microcatheter technique.
- To evaluate radiographic and clinical results in patients treated for aneurysms.
Main Methods:
- Retrospective review of 18 aneurysms in 17 patients treated over three years.
- Assessment of technical success, radiographic occlusion (modified Raymond-Roy score), and clinical outcomes (modified Rankin Scale).
Main Results:
- Successful stent deployment in all cases; 94.4% initial aneurysm occlusion rate.
- All follow-up imaging showed modified Raymond-Roy grade 1 or 2.
- Low morbidity (5.5%) and 0% mortality; all patients had modified Rankin Scale ≤2.
Conclusions:
- Y-stent-assisted coiling with the LVIS Jr via a single microcatheter technique is technically feasible.
- This method yields favorable radiographic and clinical outcomes for aneurysm treatment.

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...

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...

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...
