Background And Aims: Anti-tumor necrosis factor-α inhibitors (anti-TNFs) are the established treatment for perianal Crohn's disease (pCD), but relapse and non-response are common. Data on second- and third-line biologics are limited. We present the first direct comparison of second- and third-line biologics in pCD patients with active perianal disease previously treated with first-line anti-TNFs.

Purpose: The vertebral artery (VA) pierces the dura mater and continues with the intradural V4 segment. Once entered into the dura mater, the VA ascends from the infero-lateral to the antero-superior side of the medulla. Scarce reports of VAs compressing the medullospinal junction (MSJ) are available.

- The vertebral arteries (VAs) help supply blood to the brain and can form something called the basilar artery. The posterior inferior cerebellar artery (PICA) usually comes from these VAs.
- A study looked at 225 CT scans and discovered there are different ways PICA can start: it can be missing, come from outside the VA, through the VA's dural ring, or from inside the VA.
- Most of the time, PICA was found coming from inside the VA, but some were either missing or came from different places, which could make surgery tricky.
An Update on the Superior Cerebellar Artery Origin Type.
Medicina (Kaunas)
December 2023
Article Synopsis
- - The study focuses on the anatomical variations of the superior cerebellar artery (SCA) and its origins from the basilar artery (BA), identifying specific types including absent, preterminal, collateral, and connections from the posterior cerebral artery (PCA).
- - A total of 205 angiographic records were analyzed, revealing that the majority of SCAs originate as type 1 (71.29%), with various bilateral combinations documented, the most common being types B (1 + 1) and C (1 + 2).
- - The findings indicate that there are complex variations of SCA anatomy that are not typically covered in standard anatomy lectures, suggesting the need for tailored approaches in individual cases regarding the ends of the
: Anatomical variations of the arterial circle of Willis (cW) are common. A posterior cerebral artery (PCA) fed mostly or exclusively from the internal carotid artery is a fetal PCA (FPCA), partial (p-FPCA), or full/complete (f-FPCA), respectively. Because FPCA occurs in different anatomical configurations of the cW sides, we aimed to document in detail these morphological possibilities of FPCA within the cW.
