PTA catheter

Ulf Karl-Martin Teichgräber, Christof Klumb
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...

OBJECTIVE: Percutaneous transluminal angioplasty (PTA) of the internal jugular veins (IJVs) has been proposed in recent years to treat chronic cerebrovascular venous insufficiency, with discordant results. Moreover, very little is known about the efficacy of PTA in restoring a normal cerebral venous outflow. The aim of this study was to investigate the anatomic factors and patient characteristics that might influence the efficacy of PTA of the IJV. METHODS: There were 797 consecutive patients with venous outflow anomalies who underwent standardized, operator-independent catheter venography and PTA of the IJVs...

BACKGROUND: The effect of the insertion of guidewires and catheters on fusion accuracy of the three-dimensional (3D) image fusion technique during iliac percutaneous transluminal angioplasty (PTA) procedures has not yet been investigated. METHODS: Technical validation of the 3D fusion technique was evaluated in 11 patients with common and/or external iliac artery lesions. A preprocedural contrast-enhanced magnetic resonance angiogram (CE-MRA) was segmented and manually registered to a cone-beam computed tomography image created at the beginning of the procedure for each patient...

Background/Aims: The strategy of access care at out center involves the use of ultrasound (USG) in case of physical examination (PE) abnormality. USG determines the need of angiography. This study investigated the possible association between the need for percutaneous transluminal angioplasty (PTA) and hemodynamic parameters of USG. The study also assessed the effects of this monitoring strategy on outcomes in comparison with a historical control. Methods: A retrospective study of the medical records of 127 patients (65 PTA, 62 non-PTA) was conducted...

Venous thrombosis of pancreas transplant allografts often leads to graft loss. It is an worrisome complication and difficult to treat, forming the most common nonimmunological cause of graft loss. Multiple risk factors have been implicated in the development of venous thrombosis of pancreas transplant. Color Doppler ultrasonography enables early diagnosis of venous thrombosis, thus increasing the possibility of graft-rescue treatments. Endovascular management of pancreatic transplant vascular complications is scant and in the form of case reports...

BACKGROUND: The widespread use of central venous catheters, ports, pacemakers, and defibrillators has increased the incidence of benign superior vena cava syndrome (SVCS). This study aimed at reviewing the results of open and endovascular treatment of SVCS. METHOD: Medical literature databases were searched for relevant studies. Studies with more than five adult patients, reporting separate results for the SVC were included. Nine studies reported the results of endovascular treatment of SVCS including 136 patients followed up for a mean of 11-48 months...

Peripherally-inserted central catheters (PICC) have a greater retention time and less complications compared to central venous catheters (CVC). The study was conducted from From January of 2014 to December 2015 at Beijing DiTan Hospital, Beijing, China, and comprised 70 patients undergoing devascularisation. Of the total, 36(51.4%) patients underwent placement of PICC (Group A), while 34(48.6%) underwent had CVC (Group B). Venous catheterisation was successful in all patients. The median duration of venous catheterization in Group A was greater than that in Group B (p=0...

Monocytes are mononuclear cells characterized by distinct morphology and expression of CD14 and CD16 surface receptors. Classical, quiescent monocytes are positive for CD14 (lipopolysaccharide receptor) but do not express Fc gamma receptor III (CD16). Intermediate monocytes coexpress CD16 and CD14. Nonclassical monocytes with low expression of CD14 represent mature macrophage-like monocytes. Monocyte behavior in peripheral arterial disease (PAD) and during vessel wall directed treatment is not well defined...

OBJECTIVES: To review our experience in robot-assisted radical cystectomy, assessing the complications and oncological and functional results. MATERIALS AND METHODS: From 2007 to 2014, we performed 67 robot-assisted radical cystectomies combined with lymphadenectomy in 61 cases. The operations were performed on 37 patients due to muscle-invasive tumours and on 30 due to high-risk nonmuscle-invasive tumours. Urinary diversion was conducted extracorporeally, using a Studer neobladder in 47 cases...

PURPOSE: Paclitaxel-coated balloons (PCB) inhibit neointimal proliferation in arteries. The purpose of this retrospective analysis was to investigate the effect of PCB in in-stent restenosis after transjugular intrahepatic portosystemic shunt (TIPS) in patients with cirrhotic liver disease. MATERIALS AND METHODS: Six patients (mean age: 65 ± 10 years) with recurrent in-stent restenoses in TIPS (5 bare stents, 1 covered stent) underwent a single percutaneous transluminal angioplasty (PTA) with PCB (3 µg paclitaxel/mm(2))...

BACKGROUND: As one of the primary etiologies of the post-thrombotic syndrome, chronic venous occlusion is a huge burden on patient quality of life and medical costs. In this study, we evaluate the short-term and midterm results of endovenous recanalization by angioplasty and stenting in chronic iliofemoral deep venous occlusions. METHODS: This is a retrospective observational study set in a tertiary medical referral center. Patients with venous claudication or C4-6 venous disease combined with duplex and magnetic resonance-confirmed iliofemoral or caval occlusion were included...

BACKGROUND: Inferior vena cava (IVC) filter placement is not indicated for thrombolytic interventional treatment for deep vein thrombosis (DVT). We analyzed the efficacy and feasibility of retrievable IVC filter placement for the preventive management of embolic shedding during catheter-directed thrombectomy (CDT) for DVT of lower extremity. METHODS: Seventy patients (35 males and 35 females) who underwent retrievable IVC filter placement to prevent thrombus dislodgement during CDT in all symptomatic DVT with thrombus age suspected within 4 weeks of the lower extremity between March 2008 and January 2014 were included in this study...

In 1974, at the Medical Policlinic of the University of Zürich, German-born physician-scientist Andreas Grüntzig (1939-1985) for the first time applied a balloon-tipped catheter to re-open a severely stenosed femoral artery, a procedure, which he initially called "percutaneous transluminal dilatation". Balloon angioplasty as a therapy of atherosclerotic vascular disease, for which Grüntzig and Charles T. Dotter (1920-1985) received a nomination for the Nobel Prize in Physiology or Medicine in 1978, became one of the most successful examples of translational medicine in the twentieth century...

PURPOSE: Neointimal hyperplasia (NH) causes vascular access (VA) stenosis, which results in serious under-dialytic morbidity in hemodialysis patients. We sought to assess whether a vitamin D intervention to NH lesions leads to better VA patency and examined clinical and in vitro studies. METHODS: A pilot clinical study of six hemodialysis patients was conducted to elucidate whether 0.5 μg calcitriol injection to stenotic lesion after balloon angioplasty (PTA) maintains better vessel patency until the next follow-up angiography...

BACKGROUND: The aim of this paper was to evaluate the efficacy of percutaneous transluminal angioplasty and the intra-arterial infusion of thrombolytic drugs in the treatment of lower extremity (LE) arterial occlusion during thromboangiitis obliterans (TO). METHODS: Between February 2008 and October 2013, 13 consecutive patients with TO and LE arterial occlusion underwent 18 sessions of PTA. One LE was affected in 11 patients and both LEs in two patients. An antegrade approach with transfemoral access was used in 17 procedures, and a retrograde approach via the contralateral common femoral artery (CFA) in one procedure...
