Article Synopsis
- This study compares two surgical techniques for treating Stanford type B aortic dissections with poor proximal landing zones: 3D printing-assisted extracorporeal pre-fenestration and Castor integrated branch stent.
- In a retrospective analysis of 84 patients, both methods had a 100% surgical success rate; however, the 3D printing group had longer surgery times.
- The 3D printing approach also showed lower rates of postoperative complications, like cerebral infarction, compared to the Castor method, indicating it may be a safer option despite the longer operative time.

Article Synopsis
- The study compared two techniques for repairing the Left Subclavian Artery in patients with Stanford Type B Aortic Dissection, focusing on outcomes of 3D-printing-assisted extracorporeal fenestration versus conventional extracorporeal fenestration.
- A total of 57 patients were reviewed, highlighting key metrics such as operative time, complication rates, and aortic remodeling, with findings indicating that the 3D-printing technique had a shorter operative time and lower endoleak risk.
- Both methods were deemed safe and effective, with 3D-printing providing advantages in certain outcomes, while the conventional method showed benefits in stent modification time.
