Comparative StudyRecovery from oculomotor nerve palsy due to posterior communicating artery aneurysms: results after clipping versus coiling in a single-center series.
Oculomotor nerve palsy (ONP) is a common clinical manifestation of ruptured or unruptured posterior communicating artery (PcomA) aneurysms. Although microsurgical clip ligation has been proven a safe and durable treatment, endovascular management is emerging as an increasingly popular alternative. The aim of our study is to compare the recovery rate from ONP and assess the safety and long-term durability of both techniques. ⋯ Despite the small number of patients, our study suggests that both surgical clipping and embolization are safe and effective methods in regards to functional recovery (complete ONP recovery in about 85 % of the cases). However, coiling may lead to delayed recurrence of third cranial nerve (CN) palsy at long-term follow-up, requiring additional treatment.

Complications of titanium cranioplasty--a retrospective analysis of 174 patients.
Titanium cranioplasty (TC) has been associated with high complication rates, but abundant data are lacking. We aimed to determine the incidence and type of complications following TC and risk factors for complications. ⋯ In the largest UK study on cranioplasty to date, we have demonstrated that size of defect, traumatic aetiology and bifrontal insertion are risk factors for complications. Our results suggest that the timing of cranioplasty may be important with late (> 12 months) TC associated with a higher rate of complications, although further prospective studies on the optimal timing of TC are required to establish the observed trend. Our data can help clinicians stratify risk to inform the consent process and aid pre-operative planning.

Sinovenous thrombosis associated with skull fracture in the setting of blunt head trauma.
Emerging literature suggests that closed head injuries may be an important etiology of cerebral venous sinus thrombosis (CVST). Fractures over the dural sinuses, in particular, may predispose such patients to this secondary complication. The purpose of this study was to determine the incidence and characteristics of CVST resulting from skull fractures overlying cerebral venous sinuses at a single tertiary care center. ⋯ This report suggests that over 10 % of skull fractures involve cerebral venous sinuses, thus emphasizing the need to rule out CVST in patients suffering blunt head trauma. We propose including a venogram as part of the initial trauma work-up for these patients. Moreover, our data suggest that pediatric patients may be predisposed to less severe injuries than their adult counterparts.

Four-year trends in the treatment of cerebral aneurysms in Poland in 2009-2012.
The dilemma concerning the appropriate treatment of the intracranial aneurysms (IAs) has not yet been resolved and still remains under fierce debate. This study refers to the recent trends in the use of and outcomes related to coiling compared with clipping for unruptured and ruptured IAs in Poland over a 4-year period. ⋯ Data analysis revealed an increase in overall number of IAs treated in Poland between 2009-2012. A significant upward trend of endovascular procedures was found, whereas the number of clipped aneurysms remained relatively steady over the study period.

Overcoming CSF overdrainage with the adjustable gravitational valve proSA.
Despite progress in shunt valve technology, CSF overdrainage is still one of the most frequent complications in shunt-treated hydrocephalus. Particularly with regard to young and adolescent patients, treatment of manifest overdrainage is complicated by several hardly influenceable factors such as increasing height and mobility. Therefore, the aim of this study was to evaluate the therapeutic efficiency of the new adjustable gravitational valve, proSA. ⋯ The postoperative adjustability of the opening pressure level is the advantage of the new gravitational valve. The good clinical outcome is attributed to the new valve technology. The proSA appears to be a promising shunt valve to overcome overdrainage in adolescent and adult hydrocephalus patients.
