A well-functioning vascular access is a mainstay to perform an efficient hemodialysis procedure, which directly affects the quality of life in hemodialysis patients. We use three main types of access: native arteriovenous fistula, arteriovenous graft, and central venous catheter. Arteriovenous fistula remains the first and best choice for chronic hemodialysis. It is the best access for longevity, the lowest related complications, and for this reason, arteriovenous fistula use is strongly recommended by guidelines from different countries, including Vietnam...

When fibrosis develops in Takayasu arteritis (TA), endovascular treatment may become necessary. A 63-year-old woman with TA underwent PTA with a nitinol-structured (chocolate-like) drug-coated balloon (C-DEB PTA). She remained in remission for >1 year. The case may foster research into the use of C-DEB PTA in TA.

Background: Mechanical thrombectomy (MT) is of clinical benefit for patients with extracranial-intracranial tandem lesions of anterior circulation. However, the optimal approach to the cervical lesion of the internal carotid artery (ICA) during MT has yet to be established. Data on a conservative approach for the proximal lesion during the acute phase are scarce. Methods: A retrospective study on an institutional, prospective database was conducted. We included patients with anterior circulation stroke presenting with a tandem lesion that was approached conservatively during MT...

BACKGROUND: Cerebral venous sinus thrombosis (CVST) is a relatively uncommon cause of stroke in pediatric and young adult. The clinical course of CVST is also highly variable. In particular, coma has been noted as a predictor of poor outcome. The standard treatment for CVST in adults is systemic anticoagulation, which can lead to recanalization. Endovascular mechanical thrombectomy (EMT) is considered as possibly indicated in the event of failure to respond to anticoagulation or a comatose state...

BACKGROUND: Pulmonary delivery of flecainide results in the rapid conversion of atrial fibrillation (AF) to normal sinus rhythm in large-animal models and is safe and well-tolerated by normal human volunteers. OBJECTIVE: We investigated the effects of pulmonary delivery of flecainide on atrial and ventricular depolarization and repolarization duration. METHODS: Intratracheal instillation (1.5 mg/kg, rapid push) of flecainide or sterile water (placebo) was performed in 12 closed-chest, anesthetized Yorkshire pigs with a catheter positioned at the bifurcation of the main bronchi...

AIMS: Adaptive immunity is critical in vascular remodelling following arterial injury. We hypothesized that acute changes in T cells at a percutaneous transluminal angioplasty (PTA) site could serve as an index of their potential interaction with the injured vascular wall. METHODS AND RESULTS: T cell subsets were characterised in 45 patients with Rutherford 3-4 peripheral artery disease (PAD) undergoing PTA. Direct angioplasty catheter blood sampling was performed before and immediately after the procedure...

The number of patients in dialysis increases every year. In this review, we will evaluate the role of percutaneous transluminal angioplasty (PTA) according to patency of arteriovenous fistula and grafts. The main indication of PΤΑ is stenosis > 50% or obstruction of the vascular lumen of an arteriovenous fistula and graft. It is usually performed under local anesthesia. The infection rate is as low as the number of complications. Fistula can be used in dialysis in the same day without the need for a central venous catheter...

OBJECTIVES: The authors sought to evaluate the performance of the Ranger paclitaxel-coated balloon versus uncoated balloon angioplasty for femoropopliteal lesions at 12 months. BACKGROUND: Drug-coated balloons (DCBs) are a promising endovascular treatment option for peripheral artery disease of the femoropopliteal segment, and each unique device requires dedicated clinical study. METHODS: The prospective, randomized RANGER SFA (Comparison of the Ranger™ Paclitaxel-Coated PTA Balloon Catheter and Uncoated PTA Balloons in Femoropopliteal Arteries) study (NCT02013193) enrolled 105 patients with symptomatic lower limb ischemia (Rutherford category 2 to 4) and stenotic lesions in the nonstented femoropopliteal segment at 10 European centers...

PURPOSE: To investigate the potential of real-time magnetic particle imaging (MPI) to guide percutaneous transluminal angioplasty (PTA) of vascular stenoses in a phantom model. MATERIALS AND METHODS: Experiments were conducted on a custom-built MPI scanner. Vascular stenosis phantoms consisted of polyvinyl chloride tubes (inner diameter 8 mm) prepared with a centrally aligned cable tie to form ~ 50% stenoses. MPI angiography for visualization of stenoses was performed using the superparamagnetic iron oxide nanoparticle-based contrast agent Ferucarbotran (10 mmol (Fe)/l)...

We report three consecutive patients with limb ischemia, where symptoms appeared several days to weeks prior to presentation. In all cases, initial over-the-wire thrombectomy failed due to adherence of the thrombus to the arterial wall. We adopted a new approach of stretching the whole obstructed segment by a series of ballooning using a percutaneous transluminal angioplasty (PTA) catheter. A subsequent thrombectomy was successful in all three cases. No further intervention, such as stenting or bypass surgery, was required...

BACKGROUND: Randomized controlled trials have reported favorable 1-year outcomes with drug-coated balloons (DCBs) for the treatment of symptomatic peripheral arterial disease when compared with standard percutaneous transluminal angioplasty (PTA). Evidence remains limited on the durability of the treatment effect with DCBs in the longer term. METHODS AND RESULTS: IN.PACT SFA is a single-blind, randomized trial (Randomized Trial of IN.PACT Admiral Paclitaxel-Coated Percutaneous Transluminal Angioplasty [PTA] Balloon Catheter vs Standard PTA for the Treatment of Atherosclerotic Lesions in the Superficial Femoral Artery [SFA] and/or Proximal Popliteal Artery [PPA]) that enrolled 331 patients with symptomatic (Rutherford 2-4) femoropopliteal lesions up to 18 cm in length...

Endovascular fenestration on the abdominal aorta is effective for preventing visceral malperfusion in aortic dissection. We report a case of stented balloon fenestration before residual entry repair using the frozen elephant trunk technique for chronic aneurysmal dissection after ascending aortic replacement for DeBakey I aortic dissection. We recognized poor communication between the true lumen and false lumen in the abdominal aorta, and visceral perfusion depended almost entirely on the proximal large entry...

Importance: Chronic cerebrospinal venous insufficiency (CCSVI) is characterized by restricted venous outflow from the brain and spinal cord. Whether this condition is associated with multiple sclerosis (MS) and whether venous percutaneous transluminal angioplasty (PTA) is beneficial in persons with MS and CCSVI is controversial. Objective: To determine the efficacy and safety of venous PTA in patients with MS and CCSVI. Design, Setting, and Participants: We analyzed 177 patients with relapsing-remitting MS; 62 were ineligible, including 47 (26...

Aim Percutaneous transluminal angioplasty (PTA) is a well-accepted method to re-establish patency in stenotic and reoccluded vessels. One tool to improve results may be to use paclitaxel drug-coated balloon (DCB) catheters. This systematic review investigates whether there is a class effect among different DCBs. Methods The primary endpoint was "Freedom from Target Lesion Revascularisation" (FfTLR) after 12 months. A systematic literature search was performed in PubMed and risk of bias was assessed of the included trials...
