Percutaneous Transluminal Angioplasty for Atherosclerotic Stenosis of Vertebral Artery Origin.

: In patients with vertebral artery origin (VAO) stenosis and concomitant stenoses of other cerebral feeding arteries, data on the risk of percutaneous transluminal angioplasty (PTA) alone and with stent placement (PTAS) for VAO stenosis are limited. We aimed to determine how the presence of polystenotic lesions in other cerebral feeding arteries and concomitant carotid artery stenting (CAS) affect the periprocedural risk and long-term effect of PTA/S for atherosclerotic VAO stenosis. : In a retrospective descriptive study, consecutive patients treated with PTA/S for ≥70% VAO stenosis were divided into groups with isolated VAO stenosis and multiple stenoses.

Complex endoleak treatment after failed endovascular aortic repair.

Background: Endovascular aneurysm repair (EVAR) has created new possibilities for patients with abdominal aortic aneurysms (AAAs), and in recent years it has become tremendously popular. Use of EVAR in selected groups of patients allows mortality and morbidity to be reduced in comparison to open repair. However, complications such as endoleaks (ELs) can be of great concern and warrant urgent therapy to prevent sac rupture.

Transjugular Intrahepatic Portosystemic Shunt in Liver Transplant Recipients: Outcomes in Six Adult Patients.

Objectives: Transjugular intrahepatic portosystemic shunt (TIPS) is regularly used in treatment of clinically significant portal hypertension. Liver transplant recipients are, however, rarely indicated for the procedure. The study retrospectively examines the results of TIPS placement in 6 patients after OLT.

Percutaneous cholecystostomy in the management of acute cholecystitis - 10 years of experience.

Introduction: The preferred treatment for acute cholecystitis is cholecystectomy, but for patients with precluded general anesthesia due to critical illness or multiple medical comorbidities it is not suitable. Cholecystostomy could be a minimally invasive therapeutic alternative.

Aim: To retrospectively evaluate the indications, technical features, efficacy, complications, patients' development and relationships among monitored parameters of percutaneous computed tomography (CT)-guided cholecystostomies in cases of acute cholecystitis and find the role of this procedure in appropriate treatment selection.

Outcomes of Urgent Carotid Endarterectomy for Crescendo Transient Ischemic Attacks and Stroke in Evolution.

Background: Carotid endarterectomy (CEA) after an unstable neurological presentation is still a controversial issue. The aim of this study was to evaluate outcomes of urgent (≤48 hr) CEA in patients with crescendo transient ischemic attack (cTIA) or stroke in evolution (SIE).

Methods: A retrospective analysis was performed using prospectively collected data from all consecutive neurologically unstable patients who underwent urgent CEA during the period from January 2013 to November 2018.

Endovascular Treatment of Symptomatic Thoracic Aneurysm Due to Periaortic Lymphoma.

An aggressive periaortic lymphoma could very rarely invade the aortic wall. We present a unique case of a patient with symptomatic thoracic aneurysm and imminent rupture due to the periaortic lymphoma, in which endovascular treatment using stent graft was applied. After stabilization of the aorta and histological confirmation of aggressive B-cell lymphoma by computed tomography-guided biopsy, the antilymphoma therapy was initiated.

Fibrin Clot Architecture in Acute Ischemic Stroke Treated With Mechanical Thrombectomy With Stent-Retrievers - Cohort Study.

Background: The composition of intra-arterial clots might influence the efficacy of mechanical thrombectomy (MT) in ischemic stroke (IS) due to the acute occlusions within large cerebral arteries. The aims were to assess the factors associated with blood clot structure and the impact of thromboembolus structure on MT using stent-retrievers in patients with acute large artery IS in the anterior circulation.

Methods and results: In an observational cohort study, we studied the components of intra-arterial clots retrieved from large cerebral arteries in 80 patients with acute IS treated with MT with or without i.

Safety of Early Carotid Endarterectomy after Intravenous Thrombolysis in Acute Ischemic Stroke.

Background: The timing of carotid endarterectomy (CEA) after intravenous thrombolysis (IVT) is still a controversial issue. The aim of this study was to assess the safety of early carotid interventions in patients treated with thrombolysis for acute ischemic stroke.

Methods: A retrospective analysis was performed using prospectively collected data from consecutive patients who underwent CEA for symptomatic internal carotid artery stenosis within 14 days after the index neurological event during the period from January 2013 to July 2016.

Preservation of the Photoreceptor Inner/Outer Segment Junction in Dry Age-Related Macular Degeneration Treated by Rheohemapheresis.

Aim. To evaluate the long-term effect of rheohemapheresis (RHF) treatment of age-related macular degeneration (AMD) on photoreceptor IS/OS junction status. Methods.

Diagnosis, etiology and management of the Budd-Chiari Syndrome: a bloodcoagulation and hepatological study on the course of the disease treated with TIPS.

Background: Budd-Chiari Syndrome (BCS) is characterized by obstruction of blood flow in hepatic veins. The aim of the study was to analyze diagnosis, etiology and management of BCS.

Methods: We analyzed 44 patients (32 females, 12 males, the mean age <35y of age) treated with TIPS.

Integration of endovascular therapy of ruptured abdominal and iliac aneurysms in the treatment algorithm: a single-center experience in a medium-volume vascular center.

Purpose: To evaluate the influence of endovascular therapy of ruptured abdominal or iliac aneurysms on total mortality.

Materials And Methods: We analyzed the mortality of 40 patients from 2005 to 2009, when only surgical treatment was available. These results were compared with the period 2010 to 2013, when endovascular aneurysm repair (EVAR) was assessed as the first option in selected patients.

Influence of the secondary deployment of expanded polytetrafluoroethylene-covered stent grafts on maintenance of transjugular intrahepatic portosystemic shunt patency.

Purpose: To evaluate the effects of secondary deployment of expanded polytetrafluoroethylene (ePTFE)-covered stent grafts in the treatment of dysfunctional transjugular intrahepatic portosystemic shunts (TIPSs) in comparison with other common approaches (conventional angioplasty or implantation of bare metal stents).

Materials And Methods: A retrospective review of 121 dysfunctional bare metal TIPS presenting between 2000 and 2004 was conducted. The group was divided into four subgroups according to the type of intervention: conventional angioplasty (52 cases; 43%), bare metal stent deployment (35 cases; 28.

TIPS creation in patients with persistent left superior vena cava.

Transjugular intrahepatic portosystemic shunt is a minimally invasive endovascular procedure that has played an important role in the treatment of acute or repeated variceal bleeding or refractory ascites. The standard venous access route for this procedure is the right jugular vein. Sometimes it is better to use the left jugular vein because of lower probability of life threatening complication or technical failure.

Effect of intravascular iodinated contrast media on natural course of end-stage renal disease progression in hemodialysis patients: a prospective study.

We evaluated the impact of intravascular iodinated contrast medium on residual diuresis in hemodialyzed patients. Two groups of clinically stable hemodialyzed patients with residual diuresis minimally 500 ml of urine per day were studied. The patients from the first group were given iso-osmolal contrast agent iodixanol (Visipaque, GE Healthcare, United Kingdom) in concentration of iodine 320 mg/ml with osmolality 290 mOsm/kg of water during the endovascular procedure.
