[Hemodynamics of the transverse sinus using cine angiography]

Area of Science:

• Neurology
• Radiology
• Anatomy

Background:

• The transverse sinus (TS) is a critical venous structure in the brain.
• Previous research focused on TS anatomy but lacked hemodynamic insights.
• Cerebral angiography is a key diagnostic tool for vascular imaging.

Purpose of the Study:

• To investigate the hemodynamics of the transverse sinus (TS).
• To classify TS blood flow patterns using advanced imaging techniques.
• To provide a detailed understanding of TS blood flow dynamics.

Main Methods:

• Cerebral angiography with cinematographic films was employed.
• 35 patients underwent multi-vessel angiography using Seldinger's method.
• Contrast material infusion and manual administration were utilized.

Main Results:

• Patients were categorized into three groups based on TS features.
• Type I (dominant right TS) comprised 54.3% of cases, with diverse left TS flow patterns.
• Type II (similar bilateral TS size) accounted for 40.0%, mostly showing symmetrical flow.

Conclusions:

• Hemodynamic variations in the transverse sinus are significant.
• Cerebral angiography with cinematography effectively visualizes TS blood flow.
• This study establishes a classification for TS hemodynamics.
