AI Article Synopsis
- This study utilized 2D TOF MRV to analyze the shape of the transverse sinus in volunteers and to explore its relationship with intraocular pressure (IOP) in both eyes.
- A total of 105 participants (63 males, 42 females) were included, with those showing neurological or eye disorders excluded; they were categorized into five groups based on the transverse sinus morphology.
- Results indicated a significant correlation between asymmetry in transverse sinus shape and lower IOP in the right eye, while no correlation was found with the left eye's IOP, suggesting that a thicker transverse sinus may lead to better drainage and lower pressure in the right eye.
Article Abstract
Background And Objective: This study used two-dimensional time-of-flight magnetic resonance venography (2D TOF MRV) to show the shape of the transverse sinus and to determine whether there is a correlation between the asymmetry of the transverse sinus morphology and the intraocular pressure (IOP) of the two eyes.
Methods: In this study, 63 male and 42 female volunteers were included. Those with obvious neurological diseases and eye diseases were excluded. According to the morphology of the transverse sinus scanned with 2D TOF MRV, subjects were divided into five groups. The IOP of the volunteers was measured separately.
Results: The difference between group I and group V is statistically significant (Z = 6.78, P < 0.01). Statistically, significant differences also existed among the IOP of each group, including the mean values of both eyes and the difference between the right eye and the left eye. The asymmetry of the transverse sinus maintained a negative correlation with the right IOP (r = 0.51, P < 0.01) and the difference between the right eye and the left eye (r = 0.79, P < 0.01). The asymmetry and the left IOP had no statistical correlation.
Conclusion: The preliminary conclusion of this study is that if one side of the transverse sinus is thicker, the drainage-related ocular veins are relatively coarser, and the IOP is relatively lower. The 2D TOF MRV examination can be used as an examination to show the shape of the transverse sinus. It is a display method to provide a feasible means of inspection for a reasonable interpretation.

Objective: To evaluate the efficacy of pedicled supraclavicular flaps in hypopharyngectomy reconstruction, with a focus on preserving laryngeal function.
Methods: From August 2019 to June 2022, 14 patients with primary hypopharyngeal carcinoma who met the inclusion and exclusion criteria and underwent the repair of hypopharyngeal defects using pedicled supraclavicular flaps were included retrospectively. Relevant clinical evaluation indicators include patient characteristics, defect sizes, flap sizes, flap harvesting time, postoperative hospital stay, postoperative complications, recurrence, and survival outcomes.

Background: Malignant middle cerebral artery (MCA) infarction is one of the most devastating strokes. However, the role of the cerebral venous outflow pattern in malignant MCA infarction is not well established. We investigated the association between the transverse sinus (TS) shape and functional outcomes in patients with malignant MCA infarction.

Infantile dural arteriovenous fistula (IDAVF) is a rare complex dural arteriovenous fistulas. This study is to provide a comprehensive understanding of the angioarchitecture of arteriovenous shunts in IDAVFs and planning endovascular treatment. Five cases of IDAVF and a literature review were analyzed to characterize the shunt patterns of IDAVFs in terms of anatomic relations to the arterial feeder, sinuses, and cortical veins.

Hemifacial spasm (HFS) is an important condition for plastic surgeons to understand, as it significantly affects patients' quality of life and can complicate aesthetic and reconstructive procedures. Magnetic resonance imaging (MRI) has become vital in diagnosing HFS, assessing neurovascular relationships, and planning treatment. Transverse MRI scans often show an upward displacement of the inferior pons at the facial nerve attachment point, signaling neurovascular compression (NVC) in HFS.
