Prevalence of ruptured small and very small aneurysms: a retrospective single-centre study.

Aim Of Study: To retrospectively assess the occurrence and consequences of subarachnoid haemorrhages (SAH) caused by ruptured intracranial aneurysms (RIA), particularly focusing on the treatment outcomes of small aneurysms treated with either endovascular embolisation or surgical intervention.

Material And Methods: We retrospectively analysed data from 408 patients (144 males and 264 females) who were hospitalised between 2013 and 2022 at the Department of Neurosurgery and Neurology in University Hospital Nr 2 in Bydgoszcz, Poland. Clinical conditions at admission, assessed using the Glasgow Coma Scale, Hunt-Hess scale (H-H), modified Rankin scale (mRS), as well as age and sex, were recorded.

Interspinous Process Devices Do Not Reduce Intervertebral Foramina and Discs Heights on Adjacent Segments.

Aim: Interspinous process device (IPD) placement is an attractive treatment option for lumbar spinal and foraminal stenosis. The goal of the treatment is to release the stress on facets joints as well as decompress the nerve roots by enlarging the intervertebral foramina and narrowed canal recesses.

Purpose: To evaluate possible structural changes in the lumbar spine after implantation of an IPD on operated and adjacent segments.
