Area of Science:

Neurosurgery
Interventional Radiology
Medical Devices

Background:

Endovascular technology for intracranial aneurysms is rapidly advancing.
The SMART coil is a new microcoil designed for improved deliverability in aneurysm treatment.

Purpose of the Study:

To evaluate the initial outcomes of aneurysm embolization using the novel SMART coil.
Assess the safety and efficacy of the SMART coil in a clinical setting.

Main Methods:

Retrospective cohort study of 32 patients with 33 intracranial aneurysms.
Analysis of baseline characteristics and initial outcomes following embolization with SMART coils.
Data collected from June 2016 to January 2017.

Main Results:

No serious procedural complications were observed.
A low rate of device malfunction (3%) was reported.
High rates of immediate aneurysm occlusion (modified Raymond-Roy grade I and II) were achieved in 75% of cases.

Conclusions:

The SMART coil demonstrates a favorable initial risk-benefit profile for selected intracranial aneurysms.
Further studies are required to establish mid-term and long-term outcomes.
The device appears safe and effective for initial aneurysm embolization.
