Endovascular treatment for acute ischemic stroke in patients with tandem lesion in the anterior circulation: analysis from the METRICS study.

Background: Acute ischemic stroke (AIS) due to anterior circulation tandem lesion (TL) remains a technical and clinical challenge for endovascular treatment (EVT). Conflicting results from observational studies and missing evidence from the randomized trials led us to report a recent real-world multicenter clinical experience and evaluate possible predictors of good outcome after EVT.

Methods: We analyzed all AIS patients with TL enrolled in the prospective national study METRICS (Mechanical Thrombectomy Quality Indicators Study in Czech Stroke Centers).

Mechanical Thrombectomy Quality Indicators Study in Czech Stroke Centers: Results of the METRICS Study.

Background And Purpose: Rigorous and regular evaluation of defined quality indicators is crucial for further improvement of both technical and clinical results after mechanical thrombectomy (MT) for acute ischemic stroke (AIS). Following the recent international multi-society consensus quality indicators, we aimed to assess trend in these indicators on national level.

Material And Methods: The prospective multicenter study (METRICS) was conducted in Czech Republic (CR) in year 2019.

Instrumentation of C1 lateral mass via insertion of the posterior arch of atlas - a morphometric study.

Introduction: Instrumentation of the lateral mass of atlas via posterior arch attachment (PALMS) is a method that, unlike the traditional direct screw insertion into the lateral mass, prevents damage to the periarticular venous plexus and C2 nerve root. The method itself may be, however, limited by the anatomical situation. The small cranio-caudal pedicle dimension may lead to vertebral artery damage.

[Simple technique of percutaneous ligation of accessory veins for salvage of failing arteriovenous fistulae].

Introduction: Non-maturing arteriovenous fistula is a common problem in hemodialysis units. The main reasons for maturation failure include a poor venous system, vein stenosis, stenosis in an anastomosis, or the presence of collateral veins. Currently, the usual approach to eliminate collateral vein drainage consists in surgical ligation or coil embolization; however, these procedures are time-consuming, logistically demanding and expensive.

Causes of poor outcome in patients admitted with good-grade subarachnoid haemorrhage.

Background: Surgical risk in patients with unruptured aneurysms is well known. The relative impact of surgery and natural history of subarachnoid haemorrhage (SAH) on patients in good clinical condition (World Federation of Neurological Surgeons [WFNS] grades 1 and 2) is less well quantified. The aim of this study was to determine causes of poor outcome in patients admitted in good grade SAH.
