Venous Drainage of the Craniocervical Junction: a Retrospective Anatomical Study (SVCR MR1)

N/AActive Not RecruitingNCT06815848

University Hospital, Brest160 enrolled

Overview

This study aims to examine the feasibility of distinctly visualizing the different cervical venous networks (subcutaneous, muscular, extra-canalicular, and intra-canalicular) using dedicated magnetic resonance imaging (MRI) sequences. Theoretically, these venous networks contribute to the complex distribution of blood drainage in the cervical region, but their precise identification on imaging remains challenging.The objectives of this research are twofold: first, to assess the ability of MRI to differentiate each venous network, thereby enhancing the anatomical and functional understanding of this region; and second, to explore the possibility of grouping patients according to the predominant venous network, which could reveal significant physiological variations and specific anatomical profiles.The results could not only refine the diagnosis of cervical vascular pathologies but also guide targeted therapeutic approaches.

Outcomes

Primary Outcomes

Number of venous vessel in the four venous networks (subcutaneous, muscular, extra-canal, and intra-canal).

Determine, for each patient, which cervical venous network is dominant and identify whether each patient exhibits all four venous networks (subcutaneous, muscular, extra-canal, and intra-canal).

Time frame: at the time of inclusion

Secondary Outcomes

Number of vessel in each groups

Assess the relative significance of each identified venous network.

Time frame: at the time of inclusion

number of vessel on the left and the right in one patient

Examine whether there is a dominance of venous drainage on the right or left side in the same patient
