Anatomic feasibility of a novel modular triple-branched endograft for patients with aortic arch pathologies
Insights
A new triple-branched endograft shows anatomical feasibility in 67.4% of patients with aortic arch diseases. Anatomical limitations, such as landing zone diameter, impact suitability for this aortic arch repair device.
Area of Science:
- Vascular Surgery
- Medical Device Engineering
- Radiology
Background:
- Aortic arch diseases pose significant treatment challenges.
- Novel endovascular solutions are needed for complex aortic arch pathologies.
- Modular endografts offer potential for tailored aortic arch repair.
Purpose of the Study:
- To evaluate the anatomical feasibility of a novel modular triple-branched endograft for treating aortic arch diseases.
- To identify anatomical factors influencing the suitability of the triple-branched endograft.
Main Methods:
- A cross-sectional study analyzed computed tomography angiography (CTA) scans of 132 patients with aortic arch pathologies.
- Three-dimensional reconstructions were used to quantify anatomical features relevant to endograft deployment.
- Logistic regression identified predictors of anatomical unsuitability.
Main Results:
- The triple-branched endograft was anatomically feasible in 67.4% of the studied patient cohort.
- Major reasons for unsuitability included large proximal landing zone diameter (27.3%) and small left common carotid artery diameter (9%).
- Large proximal landing zone and small left common carotid artery diameters were significant risk factors for unsuitability (p < 0.001 and p = 0.002).
Conclusions:
- The novel triple-branched endograft shows promising anatomical feasibility for a majority of patients with aortic arch disease.
- Anatomical constraints, particularly concerning the proximal landing zone and left common carotid artery, limit current applicability.
- Future endograft designs should aim to accommodate a wider spectrum of patient anatomy for broader clinical use.
Objectives:
This study aimed to assess the anatomical feasibility of a novel modular triple-branched endograft for aortic arch diseases.
Methods:
A cross-sectional study was conducted on 314 patients with aortic arch pathologies treated at a single center from January 2018 to December 2023. Preoperative computed tomography angiography images were analyzed with three-dimensional reconstruction to quantify anatomical features. Feasibility was based on endograft anatomical criteria, and logistic regression identified risk factors for unsuitability.
Results:
Out of 132 patients included in the study, 67.4% were deemed anatomically suitable for the triple-branched device. A total of 36 (27.3%) patients were deemed inapplicable due to a large diameter of the proximal landing zone, 12 (9%) patients due to a small diameter of the left common carotid artery, and 1 (0.8%) patient due to a small diameter of the left subclavian artery. Logistic regression identified large proximal landing zone diameter and small left common carotid artery diameter were significant factors for unsuitability (p < 0.001 and p = 0.002, respectively).
Conclusions:
The novel triple-branched endograft demonstrated promising anatomical feasibility in two-thirds of patients. However, anatomical constraints limited its applicability. Future device iterations should focus on accommodating a broader range of anatomical variations.
