Objective: To investigate the effectiveness, safety, and efficacy of Atlas stents in the treatment of distal intracranial aneurysms (IAs).

Methods: We retrospectively analyzed patients with IAs who underwent stent-assisted coiling (SAC) from January 2018 to January 2022 and divided them into two groups: distal IAs treated with Atlas SAC and wide-necked aneurysms in other locations treated with SAC. The clinical data, imaging data, and postoperative follow-up data for the two groups of patients during hospitalization were collected.

Efficacy and Safety of a Dedicated Device for Cerebral Venous Thrombectomy: A Pilot Randomized Clinical Trial.

Background: Lack of a dedicated thrombectomy device for cerebral venous thrombosis hinders the recanalization ability of endovascular treatment (EVT). Novel NiTi-braided stent retriever (Venous-TD) is a dedicated venous sinus thrombectomy device. This study aims to demonstrate the safety and efficacy of Venous-TD.

Devices for aortoiliac occlusive disease.

Aortoiliac occlusive disease (AIOD) has traditionally been repaired with open surgery. However, with advancements in endovascular devices and techniques, many have adopted endovascular first approach, even for complex lesions. Stenting is the fundamental technique for endovascular treatment of AIOD, has been proven to be effective and safe.

Intravascular lithotripsy in infra-popliteal peripheral artery disease.

Chronic limb-threatening ischemia (CLTI) carries a significant risk of limb loss and thus demands urgent attention. Calcified atherosclerotic disease affecting the infra-popliteal (IP) arteries poses a formidable challenge for effective revascularization due to the narrow vessel diameter and the common presence of extensively calcified, long occlusive lesions. Intravascular lithotripsy (IVL) is an endovascular treatment that induces microfractures in the medial calcifications of blood vessels, thereby facilitating the clearance of calcified obstructive arterial lesions.

In-stent restenosis.

Endovascular arterial recanalization has become the mainstay therapy for peripheral arterial occlusive disease. Although immediate technical success is achieved in greater than 90% of cases, longer-term results continue to vary based on the clinical presentation, and the treated target lesion. In the current era, sustained patency can be expected following intervention in the carotid, coronary, renal, and iliac arteries.

Methods: Retrospective analysis of patients treated for visceral artery occlusion with thrombectomy using the AngioJet™ (Boston Scientific, MA, USA). Inclusion criteria: patients with stenotic or occluding lesion in visceral arteries including renal and mesenteric arteries, who received endovascular treatment with AngioJet™.

Imaging and endovascular management of haemoptysis in congenital heart disease.

Haemoptysis, a rare but serious complication that can arise in patients with congenital heart disease, necessitates prompt diagnosis and specialized care. The radiologist plays a critical role in this scenario, including identifying the source of haemoptysis, devising treatment plans, and delivering endovascular interventions. This article highlights the importance of imaging techniques, especially computed tomography, in identifying the cause of haemoptysis and the therapeutic value of endovascular interventions.

Interdisciplinary care of facial plexiform neurofibroma: a case report.

Background: Neurofibromatosis is considered a rare genetic disorder primarily affecting neural tissues. The most common type is neurofibromatosis type 1, which is characterized by plexiform neurofibromas.

Case Presentation: We report a case of a 30-year-old Rag-lay ethnic woman with facial plexiform neurofibroma, which not only infiltrated the left eye socket but also caused destruction of temporal bone and facial deformity.

CTP-Derived venous outflow profiles correlate with tissue-level collaterals regardless of arterial collateral status.

Background And Purpose: Tissue-level collaterals (TLC), which quantify the state of arterial blood flow transiting through cerebral ischemic tissue, have been shown to be related to the clinical outcomes of acute ischemic stroke (AIS), regardless of the arterial collateral status on computed tomography angiography(CTA). Herein, we investigated whether venous outflow (VO) profiles on computed tomographic perfusion (CTP) were linked to TLC, regardless of the arterial collateral status.

Methods: Consecutive anterior circulation AIS patients with large vessel occlusion(LVO) undergoing thrombectomy in a retrospective cohort were evaluated between January 2021 and August 2023 at two comprehensive stroke centers.

How I do it: Surgical interruption of high-flow dural arteriovenous fistulas at the foramen magnum region.

Background: Dural arteriovenous fistulas (dAVFs) in the foramen magnum region (FMR) are rare entity of dAVFs. There is no established treatment for FMR-dAVFs owing to their rarity and anatomical complexity. Herein, we report cases of high-flow dAVFs located at the posteromedial part of the FMR that were successfully treated by surgical interruption.

Natural Evolution of Incomplete Reperfusion in Patients Following Endovascular Therapy After Ischemic Stroke.

Background: A third of endovascularly treated patients with stroke experience incomplete reperfusion (expanded Thrombolysis in Cerebral Infarction [eTICI] <3), and the natural evolution of this incomplete reperfusion remains unknown. We systematically reviewed the literature and performed a meta-analysis on the natural evolution of incomplete reperfusion after endovascular therapy.

Methods: A systematic review of MEDLINE, Embase, and PubMed up until March 1, 2024, using a predefined strategy.

Methods: Retrospective analysis from a health system stroke registry, including consecutive thrombectomy patients treated within 24 hours from August 2020-December 2022 with an anterior circulation large vessel occlusion and CTP core infarct ≥50 milliliters.

Evaluation of Small Vessel Bifurcation Stenting Using the Double-Kissing Culotte and Culotte Technique in Acute Coronary Syndrome: 12-Month Clinical Outcomes.

Introduction: Patients with small vessels who undergo percutaneous coronary intervention (PCI) with subsequent multiple implantation of drug-eluting stents remain at a higher risk of unfavorable outcomes. In complex cases where maintaining flow to all side branches is part of contemporary practice, using two-stent techniques may be appropriate. This study aims to evaluate the efficacy of double-kissing (DK) culotte technique in comparison to culotte technique in the context of small-vessel therapy in patients with acute coronary syndrome (ACS).
