Safety and Efficacy of the FRED Jr Flow Re-Direction Endoluminal Device for Intracranial Aneurysms: Retrospective Multicenter Experience With Emphasis on Midterm Results
Background and Purpose: Flow diversion is increasingly used as an endovascular
treatment for intracranial aneurysms. In this retrospective multicenter study, we analyzed
the safety and efficacy of the treatment of intracranial, unruptured, or previously treated
but recanalized aneurysms using Flow Re-Direction Endoluminal Device (FRED) Jr with
emphasis on midterm results.
Materials and Methods: Clinical and radiological records of 150 patients harboring 159
aneurysms treated with FRED Jr at six centers between October 2014 and February
2020 were reviewed and consecutively included. Clinical outcome was measured by
using the modified Rankin Scale (mRS). Anatomical results were assessed according to
the O’Kelly-Marotta (OKM) scale and the Cekirge-Saatci Classification (CSC) scale.
Results: The overall complication rate was 24/159 (16%). Thrombotic-ischemic events
occurred in 18/159 treatments (11%). These resulted in long-term neurological sequelae
in two patients (1%) with worsening from pre-treatment mRS 0–2 and mRS 4 after
treatment. Complete or near-complete occlusion of the treated aneurysm according to
the OKM scale was reached in 54% (85/158) at 6-month, in 68% (90/133) at 1-year, and
in 83% (77/93) at 2-year follow-up, respectively. The rates of narrowing or occlusion of
a vessel branch originating from the treated aneurysm according to the CSC scale were
11% (12/108) at 6-month, 20% (17/87) at 1-year, and 23% (13/57) at 2-year follow-up,
respectively, with all cases being asymptomatic.
Conclusions: In this retrospective multicenter study, FRED Jr was safe and effective in
the midterm occlusion of cerebral aneurysms. Most importantly, it was associated with
a high rate of good clinical outcome
External Carotid-Internal Jugular Fistula as a Late Complication After Carotid Endarterectomy: A Rare Case
WOS: 000287323200010PubMed: 20552193A 66-year-old man presented with mild amnesia, progressive fatigue, ataxia, visual hallucinations, and debility. His past medical history included right-sided carotid endarterectomy performed elsewhere 6 years previously. Cranial magnetic resonance imaging showed left parieto-occipital arteriovenous malformation-like tortous vessels, venous congestion, and ischemic areas. Cerebral angiography showed right-sided compound external carotid artery-internal jugular vein (IJV) fistula, and distal occlusion of the right IJV. Transvenous embolization via contralateral IJV was performed, and the fistula, together with fistulous portion of the distal IJV, was sealed using coils. Two years later, patient is well with normal neurologic examination findings. The presence of an arteriovenous communication after vascular surgery is a serious complication with potential long-term effects and therefore should be diagnosed and treated as promptly as possible.Microvention Inc.The authors Bulent Bakar and Ismail Hakki Tekkok declare that they have no conflict of interest.

Iliac Vascular Complication After Spinal Surgery: Immediate Endovascular Repair Following Ct Angiographic Diagnosis
Iliac arterial injuries are rare but important complications that can develop after spinal surgery. The presentation of these M. injuries is usually late, with symptoms such as leg swelling or cardiac failure. However, acute massive bleeding may be a sign of early presentation as in our patient. Herein, we present a case of life-threatening bleeding with early computed tomography angiographic diagnosis of common iliac artery pseudoaneurysm and iliac arteriovenous fistula secondary to spinal surgery which was successfully managed by endovascular stent graft treatment.WoSScopu

Long-term clinical and angiographic follow-up results of the dual-layer flow diverter device (FRED) for the treatment of intracranial aneurysms in a multicenter study.
Purpose Our aim was to determine the long-term safety and efficacy of the Flow Re-Direction Endoluminal Device (FRED) in this multicenter study with prospective design. Materials-method This study included 136 consecutive patients with 155 aneurysms treated between March 2013 and June 2016 in 10 centers. Twenty-two (16.2%) patients presented with rupture of the index aneurysm. Large/giant aneurysms comprised 1/3 of the cohort. Adjuvant coil use during the treatment was 15.5%. The effectiveness measure in the study was the percentage of aneurysms with stable occlusion at follow-up. Results Vascular imaging follow-up was performed at least once in 131/136 (96.3%) patients with 148/155 (95.5%) aneurysms up to 75 months (mean: 37.3 months; median: 36 months according to latest follow-up), and 102/155(65.8%) aneurysms in 90/136 (66.2%) patients had >= 24-month control. According to the latest controls, the overall stable occlusion rate was 91.9% (95% CI, 87.5 to 96.3%). Three out of 148 aneurysms with follow-up were retreated (2%, 95% CI 0.0 to 4.3%). Adverse events were noted in 19/136 (14%, 95% CI, 9 to 21%) patients with a morbidity of 1.5% (95% CI, 0.0 to 3.5%). Mortality was 1/136 (0.7%, 95% CI, 0.02 to 2.2%) and was unrelated to aneurysm treatment. In-stent stenosis (ISS) was detected in 10/131 of the patients with follow-up (7.6%, 95% CI; 3.1 to 12.2%), only one being symptomatic. No adverse events have occurred in any of the patients with follow-up after 24 months, except the one resulting from ISS. Conclusion In the treatment of cerebral aneurysms which were candidates for flow diversion technique, this study showed long-term efficacy of FRED with good safety and occlusion rates
