Stent-assisted coiling of intracranial aneurysms arising from small vessels (≤ 2.0 mm) is a common procedure. However, data regarding its treatment outcomes are scarce. This study evaluated the clinical and radiologic stent-assisted using low-profile stents for parent arteries.From November 2015 to October 2020, sixty-four patients with 66 arteries ≤2.0 mm were treated Low-Profile Visualized Intraluminal Support Junior (LVIS Jr) or Neuroform Atlas stent in single institution. The...
BACKGROUND AND OBJECTIVES: Postclipping cerebral infarction (PCI) remains a major concern after treatment for unruptured intracranial aneurysms (UIAs). However, studies of microsurgical clipping based on diffusion-weighted imaging are limited. We aimed to present the incidence, risk factors, and types PCI its radiological clinical characteristics. METHODS: This was retrospective single-center study in which patients were scheduled undergo anterior circulation UIAs. The overall incidence...
Up to 15% of all patients with brain metastases have no clearly detected primary site despite intensive evaluation, and this incidence has decreased the use improved imaging technology. Radiosurgery been evaluated as one treatment modality for limited metastases. In study, we effectiveness radiosurgery from unknown tumors.We retrospectively 540 who underwent gamma knife (GKRS) radiologically diagnosed between August 1992 September 2007 in our institution. First, were grouped into...
Here we report a case of penetrating neck injury to the posterior fossa that was shown, using high-resolution computed tomography (HRCT) and digital subtraction angiography (DSA), involve no vascular injury. A 54-year-old man brought emergency department after left side occipital area with knife. He in an intoxicated state could not communicate readily. On initial examination, his vital signs were stable there active bleeding from site. Because concern about possible adjacent vessels,...
On March 11, 2020, the World Health Organization declared coronavirus disease 2019 (COVID-19) outbreak a pandemic. 1Many countries have tried to prevent spread of COVID-19 by avoiding physical contact and improving personal hygiene in public life.In medical institutions, further restrictions also been implemented under limited resources, most resources used cope with pandemic.However, these efforts CO-VID-19 caused significant changes diagnosis treatment processes acute illness clinical...
Deciphering the anatomy of posterior communicating artery (PCoA) aneurysms in relation to surrounding structures is essential determine adjuvant surgical procedures. However, it difficult predict through preoperative imaging studies. We aimed present anatomical using high-resolution three-dimensional proton densityweighted turbo spin-echo magnetic resonance (PDMR) with simple classification.From January 2020 April 2022, 30 patients underwent PDMR before microsurgical clipping for unruptured...
BACKGROUND AND OBJECTIVE: Perioperative low-dose aspirin (ASA) management for open craniotomy surgery lacked information. We analyze to establish the perioperative ASA strategy minimize both hemorrhagic and thromboembolic complications. METHODS: The investigators designed a multicenter retrospective study, which included patients scheduled have clipping unruptured intracranial aneurysm. incidence risk factors were analyzed postoperative complications major cardio- cerebrovascular events...
Abstract Background This retrospective cross-sectional study aimed to investigate the course of newly onset moderate-to-severe headaches in patients who underwent endovascular treatment (EVT) for unruptured intracranial aneurysms (UIAs). Methods Between September 2009 and May 2022, 412 were included, all met following criteria: (1) presence UIAs on computed tomography angiography or magnetic resonance angiography; (2) headache (Numeric Rating Scale, NRS ≥ 4) around time diagnosis; (3) EVT...
The survival rate of aneurysmal subarachnoid hemorrhage (aSAH) has gradually increased, leading to more clinical cases de novo intracranial aneurysms (DNIAs).To identify the characteristics patients with DNIA growth or rupture.We included 1601 aSAH treated by clipping from January 1993 May 2010. According inclusion and exclusion criteria, 233 had no DNIAs, 63 77 DNIAs. We assessed incidence DNIAs risk factors for formation. After dichotomizing group into heed (patients rupture growth) stable...
<h3>Introduction</h3> The Surpass Evolve Flow Diverter (SE-FD) was launched in 2019 as a new generation FD of Streamline. <h3>Aim Study</h3> We aimed to assess and report the effectiveness safety SE-FD insertion for unruptured intracranial aneurysms at six-month one-year follow-up. <h3>Methods</h3> Between November October 2021, total 106 patients with 108 were treated single institution. Of these, performed 40 41 aneurysms. At follow up, clinical radiologic outcomes retrospectively...
Surpass Evolve Flow Diverter (SE-FD; Stryker Neurovascular, Kalamazoo, MI, USA) was launched in 2019 as a new generation FD of Streamline. The aim this study to report the effectiveness and safety SE-FD insertion for unruptured intracranial aneurysm at one-year follow-up.Between November October 2021, total 106 patients with 108 aneurysms were treated single institution. Of these, performed 40 41 aneurysms. At follow-up, clinical angiographic outcomes retrospectively evaluated from...
Abstract BACKGROUND AND PURPOSE: Ventriculostomy-associated infection (VAI) is a serious complication of external ventricular drainage (EVD). Infection rates and risk factors are variable in the literature due to heterogeneity EVD procedures management. This study aimed investigate incidence VAI its associated two institutions with identical procedural management protocols. METHODS: The authors reviewed medical records patients older than 18 years who received placements between January 2015...
