Summary
The Navien guide catheter demonstrated high success in neurointerventional procedures, offering excellent trackability and distal access even in tortuous arteries with minimal complications.
Area of Science:
- Neurosurgery
- Interventional Radiology
- Medical Device Technology
Background:
- Catheter technology advancements enhance flexibility and trackability.
- Neurointerventional procedures require precise catheter navigation.
Purpose of the Study:
- To evaluate the efficacy and safety of the Navien guide catheter in neurointerventional cases.
- To assess the catheter's performance in achieving distal access and managing vessel tortuosity.
Main Methods:
- Retrospective analysis of 265 consecutive single-center neurointerventional cases.
- Data collected included procedure type, catheter size, access route, tip position, and complications.
- Vessel tortuosity was graded, and catheter success in navigating these segments was recorded.
Main Results:
- The Navien catheter (5F and 6F) was used in 265 procedures, with high success rates.
- Successful distal access was achieved in 93% of cases with proximal artery tortuosity (grade B or C).
- The overall success rate without catheter complication was 97%, with a low incidence of adverse events (0.8% total).
Conclusions:
- The Navien guide catheter is effective for neuroendovascular interventions, providing reliable distal access.
- It performs well even in challenging anatomies, including tortuous vessels.
- The catheter exhibits a low complication rate, supporting its use in neurointerventional practice.

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

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...

1.8K
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

1.2K
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
