Vascular Cross-Section, Rather Than Tortuosity, Can Classify First-Pass Outcome of Mechanical Thrombectomy for Ischemic Stroke.

ABSTRACT:

Background

Vascular geometry plays an important role in stroke thrombectomy outcomes, but few studies have examined complex characteristics of vessel morphology. The authors hypothesized that engineered vessel cross-section features could be used to predict thrombectomy first-pass effect (FPE).

Methods

The authors analyzed computed tomography angiography and noncontrast computed tomagraphy from 50 patients with anterior circulation stroke thrombectomy. After segmentation, traditional metrics (vessel tortuosity and angulation) were calculated from vessel centerlines that were transformed into the same coordinate system and same region of interest. Univariate statistical analysis and geometric morphometrics were used to interrogate differences in geometry between cases that di
