The Sutureless Excimer Laser Anastomosis Clip Pilot Study: a feasibility and safety study

Area of Science:

• Neurosurgery
• Vascular Surgery
• Medical Device Development

Background:

• The excimer laser-assisted non-occlusive anastomosis (ELANA) bypass technique is advantageous for complex aneurysms but technically demanding.
• A novel sutureless ELANA Clip device (SEcl) was developed to simplify the ELANA technique by eliminating the need for intricate suturing.
• This study evaluates the clinical feasibility and safety of the SEcl technique for treating challenging intracranial aneurysms.

Purpose of the Study:

• To investigate the clinical feasibility and safety of the sutureless ELANA Clip (SEcl) device.
• To assess the applicability and technical aspects of the SEcl technique in complex aneurysm cases.
• To evaluate patient outcomes following SEcl bypass surgery for last-resort aneurysm treatment.

Main Methods:

• Three patients with complex, large anterior circulation aneurysms unsuitable for standard treatments were selected.
• SEcl bypass surgery was performed after multidisciplinary consensus, preoperative evaluation, and informed consent.
• The study assessed the applicability, technical aspects, and patient outcomes of the SEcl technique.

Main Results:

• Successful exclusion of all aneurysms from circulation was achieved.
• Intracranial anastomosis creation using the SEcl device was faster and easier.
• No device-related serious adverse events occurred, with favorable patient outcomes (one stable, two improved).

Conclusions:

• The sutureless ELANA Clip (SEcl) anastomosis technique is feasible and relatively safe for difficult-to-treat, last-resort aneurysm cases.
• SEcl represents a viable treatment option for complex intracranial aneurysms where other methods are unsafe.
• Further research is recommended to minimize clip size and explore SEcl applications in cardiac surgery.
