Comparison of the diagnostic efficacy between virtual portal pressure gradient and hepatic venous pressure gradient in patients with cirrhotic portal hypertension.

Objectives: This study aimed to evaluate the performance of virtual portal pressure gradient (vPPG) and its associated hemodynamic parameters of 3-dimensional (3D) model in patients with cirrhosis.

Methods: Seventy cirrhotic patients who underwent both hepatic venous pressure gradient (HVPG) measurement and vPPG calculation were prospectively collected. The ideal-state model (ISM; n = 44) was defined by sinusoidal PH without hepatic vein shunt or portal vein thrombosis, whereas those not conforming to the criteria were classified as non-ISM (n = 26).

Endovascular treatment of symptomatic severe intracranial atherosclerotic stenosis with a novel intracranial dedicated drug-eluting stent: a more effective treatment approach.

Background: Endovascular treatment of severe intracranial atherosclerotic stenosis (ICAS) using coronary drug-eluting stents (DESs) significantly reduces the risk of in-stent restenosis (ISR) and stroke recurrence. However, there are few reports regarding the treatment of ICAS with intracranial dedicated DES. Herein, we present our experience with the feasibility, safety, and medium-term follow-up outcomes of a novel intracranial DES, named NOVA stent, in patients with symptomatic severe ICAS (≥70%).

Predictors of successful endovascular recanalization in patients with symptomatic nonacute intracranial large artery occlusion.

Background: Endovascular recanalization in patients with symptomatic nonacute intracranial large artery occlusion (ILAO) has been reported to be feasible, but technically challenging. This study aimed to determine the predictors of successful endovascular recanalization in patients with symptomatic nonacute ILAO.

Methods: The outcomes of endovascular recanalization attempts performed in 70 consecutive patients showing symptomatic nonacute ILAO with hemodynamic cerebral ischemia between January 2016 to December 2022 were reviewed.

Endovascular Treatment of Complex Vascular Diseases of the Internal Carotid Artery Using the Willis Covered Stent: Preliminary Experience and Technical Considerations.

The Willis covered stent (WCS) is used to treat complex vascular diseases of the internal carotid artery; however, its performance requires further investigation. This study aimed to present our single-center clinical results and experience of endovascular repair of complex vascular diseases of the internal carotid artery using the WCS. Patients who presented with complex vascular diseases of the internal carotid artery and who were treated with the WCS from December 2013 to September 2018 were retrospectively reviewed.

Endovascular recanalization for symptomatic subacute and chronic intracranial large artery occlusion of the anterior circulation: initial experience and technical considerations.

Purpose: This study aimed to report the clinical findings and initial clinical experience of endovascular recanalization for symptomatic subacute/chronic intracranial large artery occlusion (ILAO) of the anterior circulation.

Methods: From October 2015 to December 2017, 13 patients with symptomatic subacute/chronic ILAO of the anterior circulation were enrolled in this study and underwent endovascular recanalization. We collected the initial procedural results, including the rate of successful recanalization and periprocedural complications, and data pertaining to angiographic and clinical follow-up.

A single-center experience in the endovascular treatment of carotid siphon aneurysms using the Willis covered stent: a retrospective analysis.

Objective: To report the clinical results and initial clinical experience of endovascular isolation with the Willis covered stent for carotid siphon aneurysms.

Methods: Between November 2013 and December 2016, a total of 57 patients who presented with carotid siphon aneurysms were treated with the Willis covered stent. Results of the procedures, technical events, and complications were recorded.

Endovascular isolation of intracranial blood blister-like aneurysms with Willis covered stent.

Objective: Intracranial blood blister-like aneurysm (BBA) is a rare type of aneurysm that lacks all layers of the arterial wall. These fragile aneurysms have the propensity to rupture with minimal manipulation, which makes them hazardous and difficult to treat. The present study evaluated the safety and feasibility of endovascular treatment of BBAs with the Willis covered stent.

[Long-term outcome of interventional therapy for malignant biliary obstruction: a retrospective analysis of 109 cases].

Objective: To evaluate the long-term outcome and its relative influenced factors of interventional therapy in dealing malignant biliary obstruction (MBO).

Method: 109 MBO patients, 54 males and 55 females, aged (71 +/- 12), underwent interventional therapy: 55 patients received percutaneous transhepatic cholangiography and drainage (PTCD), and 54 underwent bile duct stent implantation. One week later, total bilirubin (TB), direct bilirubin (DB), and alanine transaminase (ALT) were examined, and Child-Pugh scoring was conducted.
