We took all the 6 patients in our study and followed them up.

All of the 6 repairs were successful, and no CSF leak was found just after the operation in 6- to 48-month follow-up.

We recommend our modified novel temporoparietal myofascial flap as a very good option in case of failed cases of postoperative CSF leak.

Commissural fibers are necessary for bilateral integration, body coordination, and complex cognitive information flow between the hemispheres. The anterior commissure (AC) has a complex architecture interconnecting areas of the frontal, temporal and occipital lobes. The present study aims to demonstrate the connections and the course of the anterior (ACa) and posterior (ACp) limb of the AC using fiber dissection and diffusion tensor imaging (DTI) of the human brain.

Fiber dissection was performed in a stepwise manner from lateral to medial on 6 left hemispheres. The gray matter was decorticated and the ACa-ACp was exposed. The ACa and ACp tracts were demonstrated using a high-spatial-resolution DTI with a 3T magnetic resonance unit in 13 cases.

Using both techniques showed that the AC has complex interconnections with large areas of the frontal (olfactory tubercles, anterior olfactory nucleus, olfactory bulb, and the orbital gyri), temporal (amygdaloidal nuclei, temporal and perirhinal cortex), and occipital (visual cortex) lobes. The ACp makes up the major component of the AC and is composed of temporal and occipital fibers. We observed that these fibers do not make a distinct bundle; the temporal fibers joined the uncinate fasciculus and the occipital fibers joined the sagittal striatum to reach their targets.

Being aware of the course of the AC isimportant during transcallosal and interforniceal approaches to the third ventricle tumors and temporal lobe epilepsy surgery. The intermingling fibers of the AC can provide a better understanding of the unexplained deficit that may occur during regional surgery.

Conventional coiling is standard for treatment of ruptured intracranial aneurysms. We compared clinical and angiographic outcomes between intrasaccular flow disruption with the Woven EndoBridge (WEB) and conventional coiling in patients with aneurysmal subarachnoid hemorrhage (aSAH) using a propensity score-matched analysis.

This is a retrospective study of consecutive patients with aSAH treated with the WEB or conventional coiling between 2010 and 2019. Baseline characteristics, procedural complications, angiographic results, and functional outcome were compared between both groups.

Fifty-two patients treated with the WEB and 236 patients treated by coiling were included. The WEB group was characterized by a higher patient age (P= 0.024), a wider aneurysm neck (P < 0.001), and more frequent location at the posterior circulation (P= 0.004). Procedural complications were comparable between WEB (19.2%) and coiling (22.7%, P= 0.447). In-hospital mortality rates were higher in the coiling group (WEB 5.8%s, in particular for those with wide-necked and thus challenging anatomy.

Surgery is the definitive treatment option for symptomatic Chiari malformation I (CMI), but there is no clear consensus as to the preferred surgical method. This study aimed to quantitatively assess and compare the effect and safety of dura splitting decompression (DSD) and posterior fossa decompression with duraplasty (PFDD) in treating patients with CMI.

A literature search of EMBASE, MEDLINE, PubMed, Cochrane Library, and Web of Science databases was conducted. References from January 1990 to September 2020 were retrieved. We only included papers containing original data, comparing the use of DSD and PFDD in CMI patients.

Overall, 11 relevant studies were identified, wherein 443 patients treated for CMI by DSD were compared with 261 patients treated by PFDD. No difference was observed between PFDD and PFD in terms of clinical improvement (P= 0.69), syringomyelia improvement (P= 0.90), or reoperation (P= 0.22). DSD was associated with shorter operation durations (P= 0.0007), shorter length of stay (P=te, especially those related to incidence of CSF-related complications. More evidence from advanced multicenter studies are needed to require to validate the findings.

Neurosurgery is a specialty associated with high risk of malpractice claims, which can be influenced by quality and safety of care. Diagnostic errors have gained increasing attention as a potentially preventable problem. Selleck Tamoxifen Despite the burden of diagnostic errors, few studies have analyzed diagnostic errors in neurosurgery. We aimed to delineate the effect of diagnostic errors on malpractice claims involving a neurosurgeon.

This retrospective study used the national Japanese malpractice claims database and included cases closed between 1961 and 2017. To examine the effect of diagnostic errors in neurosurgery, we compared diagnostic error-related claims (DERCs) with non-DERCs in indemnity, clinical outcomes, and factors relating to neurosurgeons.

There were 95 closed malpractice claims involving neurosurgeons during the study period. Of these claims, 36 (37.9%, 95% confidence interval [CI] 28.7%-47.9%) were DERCs. Patient death was the most common outcome associated with DERCs. Wrong, delayed, and missed diagnosis occurred in 25 (69.4%, 95% CI 53.1%-82.0%), 4 (11.1%, 95% CI 4.4%-25.3%), and 7 (19.4%, 95% CI 9.8%-35.0%) cases, respectively. The most common presenting medical condition in DERCs was stroke. Subarachnoid hemorrhage, accounting for 85.7% of stroke cases, led to 27.8% of the total indemnity paid in DERCs.

DERCs are associated with higher numbers of accepted claims and worse outcomes. Identifying diagnostic errors is important in neurosurgery, and countermeasures are required to reduce the burden on neurosurgeons and improve quality. This is the first study to focus on diagnostic errors in malpractice claims arising from neurosurgery.
