Summary
Newly developed platinum minicoils enable effective super-selective embolisation in patients. This technique simplifies procedures, reducing the need for additional surgery and offering controlled vascular interventions.
Area of Science:
- Interventional Radiology
- Vascular Surgery
- Medical Device Technology
Background:
- Super-selective embolisation is crucial for treating various vascular pathologies.
- Minimally invasive techniques are increasingly preferred for improved patient outcomes.
- The development of novel embolic agents is essential for advancing interventional procedures.
Purpose of the Study:
- To evaluate the clinical usability and effectiveness of new mechanically applicable minicoils.
- To assess the performance of wire-attached minicoils for super-selective embolisation.
- To determine the safety and efficacy of this novel embolisation system.
Main Methods:
- Platinum minicoils attached to a guide wire were used in 16 patients (ages 28-90).
- Indications included haemorrhages, false aneurysms, traumatic lesions, and arteriovenous fistulas.
- Application was performed via microcatheter using a coaxial technique.
Main Results:
- Successful percutaneous embolisation was achieved in all patients.
- No additional surgical intervention was required post-embolisation.
- The system demonstrated ease of manipulation and controlled embolisation, with one recoverable instance of peripheral displacement.
Conclusions:
- The minicoils facilitate effective super-selective embolisation.
- Due to cost considerations, their use should be prioritized in vascular regions with minimal risk of displacement.
- Adequate experience with embolisation techniques is necessary for optimal application.
