Article Synopsis
  • Crossing Y-stent-assisted coiling (CYSAC) is a promising method for treating challenging wide-neck bifurcation aneurysms, although it can be technically difficult.
  • A study involving 37 patients treated with Y-stent-assisted coiling using LVIS EVO stents showed that a significant majority (83.8%) achieved excellent occlusion immediately after treatment, with high success rates maintained over an average follow-up of nearly 33 months.
  • The researchers' "drill turn" technique for stent crossing was effective, leading to safe outcomes and stable occlusion rates, demonstrating the method's feasibility for treating these aneurysms.

Objective: The aim of this study was to determine the incidence of pressure ulcers (PUs) in patients treated for acute ischaemic stroke (AIS) and to evaluate comorbid/confounding factors.

Method: The study included patients treated for AIS who were divided into three treatment groups: those receiving intravenous tissue plasminogen activator therapy (tPA); patients receiving mechanical thrombectomy (MT); and those receiving both tPA and MT. PUs were classified according to the international classification system and factors that may influence their development were investigated.

Background: Currently, there is still no clear consensus on bridging thrombolysis (BT) before mechanical thrombectomy (MT). In this study, we aimed to compare clinical and procedural outcomes and complication rates of BT versus direct mechanical thrombectomy (d-MT) in anterior circulation stroke.

Methods: A total of 359 consecutive anterior circulation stroke patients who received d-MT or BT in our tertiary stroke center between January 2018 and December 2020 were retrospectively analyzed.

Purpose: The predicting bleeding complications in patients undergoing stent implantation and the subsequent dual antiplatelet therapy (PRECISE-DAPT) score predicts the risk of bleeding in patients with dual antiplatelet therapy (DAPT) after percutaneous coronary interventions (PCIs). Patients with carotid artery stenting (CAS) are also treated with DAPT. In this study, we aimed to investigate the performance of the PRECISE-DAPT score in predicting bleeding in patients with CAS.

Article Synopsis
  • The LVIS EVO is a new self-expandable stent designed for treating wide-necked intracranial aneurysms, offering full visibility and a high metal coverage ratio.
  • A study involving 103 patients showed a technical success rate of 100%, with 77.7% achieving complete occlusion immediately after the procedure and 89% maintaining this occlusion at follow-up.
  • The treatment proved to be safe and effective, with a low complication rate and most patients achieving good neurological outcomes.

Introduction: The aim of this study is to present a series of six cases with thoracoabdominal aneurysm treated with hybrid technique in our center.

Methods: Between May 2015 and December 2018, the data of six patients with thoracoabdominal aneurysms and various comorbidities who underwent visceral debranching followed by endovascular aortic aneurysm repair were reviewed retrospectively.

Results: Patients' mean age was 65.

Background: Self-expandable stents have been increasingly used for endovascular treatment of intracranial aneurysms. Because the usage of intracranial stents has increased overall, total numbers of complications associated with these devices have increased. Thrombosis, distortion, or incomplete opening of stents are potential complications that may result in occlusion of the parent artery.

Article Synopsis
  • The study evaluated the technical success and safety of the Silk Vista (SV) device for treating intracranial aneurysms across multiple institutions.
  • It reviewed data from 57 procedures involving 60 aneurysms, showing high success rates in device opening (91%) and complete wall apposition (92%).
  • The findings indicated that the SV device is both feasible and technically safe, with a low rate of complications and no reported mortality.

Background/aim: In this study, we aimed to investigate what should be regarded as potential determinants of treatment strategies when evaluating 3D digital subtraction angiography (DSA) images.

Material And Methods: Our inclusion criteria were as follows: (1) presence of at least one intracranial aneurysm demonstrated by conventional angiography, (2) having both 2D and 3D images, and (3) being over 18 years old. First, two-dimensional (2D) and then 3D angiography images of 226 aneurysms of 150 patients were scanned.
