Clinical use of reserved guide wire fenestration and Viabahn-covered stent in Stanford type B aortic dissection with left subclavian artery involvement.
Zhu H & Zhu H • The Journal of international medical research • 2026
External stent fenestration with a reserved guide wire and Viabahn-covered stent demonstrated significant efficacy in treating Stanford type B aortic dissection involving the left subclavian artery, achieving full technical success with no postoperative deaths, minimal complications, and shorter hospital stay versus the conventional in-situ fenestration approach.
Key Findings
Results
The reserved guide wire external fenestration technique with Viabahn-covered stent achieved full technical success in vessel reconstruction for all treated patients.
Eight patients with Stanford type B aortic dissection involving the left subclavian artery were treated from March 2023 to May 2024.
The study was conducted at Yinzhou People's Hospital.
Technical success was achieved in 100% of cases with complete vessel reconstruction.
The novel technique was compared against traditional in-situ fenestration as the conventional approach.
Results
No postoperative deaths occurred in patients treated with the reserved guide wire external fenestration and Viabahn-covered stent technique.
All eight patients survived the procedure without mortality.
Minimal complications were reported in the treatment group.
Follow-up period ranged from 1 to 3 months.
The complication incidence was significantly reduced compared to the conventional in-situ fenestration approach.
Results
The novel external fenestration technique resulted in a shorter hospital stay compared to the conventional in-situ fenestration approach.
Hospital stay duration was reduced with the reserved guide wire plus Viabahn stent method versus traditional in-situ fenestration.
The study population consisted of eight patients treated over a period from March 2023 to May 2024.
Specific numerical values for hospital stay duration were not provided in the abstract.
The reduction in hospital stay was noted as one of the clinical advantages of the new technique.
Results
Fenestration complication incidence was significantly reduced with the reserved guide wire external fenestration technique during the follow-up period.
Follow-up was conducted over a period of 1 to 3 months.
The reduction in fenestration complications was described as 'significantly reduced' compared to the conventional approach.
The sample size was limited to eight patients, and the authors acknowledged the need for larger sample studies to verify results.
The technique was noted to result in 'substantial improvements in prognosis in terms of complications.'
