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.

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.

The intraoperative portable CT scanner-based spinal navigation: a viable option for instrumentation in the region of cervico-thoracic junction.

Purpose: Innovative intraoperative imaging modalities open new horizons to more precise image acquisition and possibly to better results of spinal navigation. Planning of screw entry points and trajectories in this prospective study had been based on intraoperative imaging obtained by a portable 32-slice CT scanner. The authors evaluated accuracy and safety of this novel approach in the initial series of 18 instrumented surgeries in anatomically complex segment of cervico-thoracic junction.

Prognostic impact of hemoglobin level prior to radiotherapy on survival in patients with glioblastoma.

Purpose: To evaluate prognostic factors in patients with glioblastoma treated with postoperative or primary radiotherapy.

Patients And Methods: From 1989 to 2000, a total of 100 patients underwent irradiation as part of their initial treatment for glioblastoma. All patients had undergone surgery or biopsy followed by conventional external-beam radiotherapy.
