The Electrified Wire Technique in Complex Aortic Interventions: A Case Series.

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Medical Devices

Background:

• Electrosurgery is established in endovascular procedures.
• Its application in aortic interventions is limited, with only case reports available.
• A novel electrified wire technique offers a new approach for complex aortic procedures.

Purpose of the Study:

• To present a case series on the use of an electrified wire for catheter-based electrosurgery in complex aortic interventions.
• To evaluate the feasibility, safety, and effectiveness of this technique.

Main Methods:

• A retrospective case series of patients undergoing complex aortic surgery from October 2020 to August 2023.
• The electrified wire technique was used for dissection flap perforation, LSA in situ fenestration, and aortic atresia crossing.
• Methods included detaching insulation from a PTFE-coated guidewire and attaching an electrocautery pen.

Main Results:

• The technique was applied in 12 cases (11 aortic dissections, 1 aortic atresia).
• Successful application was achieved in all cases, including flap perforation, cheese-wire technique, and LSA fenestration.
• No complications related to the electrified wire technique were reported.

Conclusions:

• The electrified wire technique is a feasible, readily available, and safe tool for complex aortic interventions.
• It is particularly useful for perforating aortic tissue and performing in situ fenestrated repairs.
• The technique has potential applications in various vascular procedures requiring vessel or prosthetic crossing.
