PURPOSE: To report our initial experience of fully percutaneous deep venous arterialization (pDVA) for the treatment of chronic critical limb ischemia (cCLI) after failed distal angioplasty. MATERIALS AND METHODS: pDVA was performed in five consecutive patients by creating an arteriovenous fistula (AVF) between a below the knee artery and its satellite deep vein. In this early experience, only patients with failed prior interventional attempts at establishing flow with no distal targets for an arterial bypass were selected...

Less than 1% of patients with liver metastases from neuroendocrine tumors (NETs) are susceptible to liver transplantation. We report a case of a patient transplanted 13 years ago for NET metastases, with a lesion histologically proved for NET metastasis located at the cava vein anastomosis. He was treated with percutaneous radiofrequency ablation (RFA) after a first failed attempt of endovascular approach. The vascular heat sink, which RFA is susceptible to, was considered an advantage in this case, since it restricted the propagation of heat only to the tissue located in the very proximity of the RFA antenna, protecting the inferior vena cava vessel walls...

INTRODUCTION: Dysfunctional or infected hemodialysis polyester-cuffed catheters often require removal and are dissected out. The DermaPort™, percutaneous vascular access system (PVAS) permanently integrates a titanium mesh with the skin forming a stable, sterile barrier that allows for catheter placement, adjustment, or catheter exchange. This study aimed to describe the use and clinical outcomes of the DermaPort PVAS. METHODS: Thirty-eight patients who were receiving hemodialysis via a tunneled catheter were enrolled in this prospective open-label study...

PURPOSE: In patients with acute occlusions of the middle cerebral artery, the collaterals play an important role in infarct growth and potentially on clinical outcome. As the primary collateral pathway, the posterior cerebral artery with the posterior communicating artery (PComA) is important. We analyzed the influence of the presence of an ipsilateral PComA on infarct growth and clinical outcome. METHODS: We included 101 patients with M1 occlusions and subsequent endovascular treatment and differentiated patients without an ipsilateral PComA from those with an ipsilateral PComA...

PURPOSE: The aim of this study is to assess the feasibility of aspiration mechanical thrombectomy in patients with massive and submassive pulmonary embolism (PE) and contraindications to thrombolysis. MATERIALS AND METHODS: Eighteen patients presenting massive (8/18) or submassive (10/18) PE were prospectively enrolled between October 2016 and November 2017. All the patients enrolled had contraindications to thrombolysis (haemorrhagic stroke n = 1, ischaemic stroke in the preceding 6 months n = 7, central nervous system damage or neoplasms n = 1, recent major trauma/surgery/head injury in the preceding 3 weeks n = 5, gastrointestinal bleeding within the last month n = 4)...

PURPOSE: To experimentally investigate a new homogenously paclitaxel/resveratrol-coated balloon catheter in terms of transport of the coating to the treated tissue and local effects including histology and functional tests. METHODS: Adherence of the coating to the balloon was explored by in vitro simulation of its passage to the lesion. Paclitaxel and resveratrol transfer to the vessel wall was investigated in porcine coronary and peripheral arteries. Matrix-assisted laser desorption/ionization (MALDI) was used for direct microscopic visualization of paclitaxel in arterial tissue...

Venous thromboembolism (VTE) is a major public health issue; deep vein thrombosis (DVT) affects about 1/1000 patients. Each year, VTE kills more patients in Western Europe than breast cancer, prostate cancer, acquired immune deficiency syndrome (AIDS) and road traffic accidents combined and is responsible for the deaths of approximately 370,000 European citizens (Cohen et al. in Thromb Haemost 98:756-764, 2007; Bĕlohlávek et al. in Exp Clin Cardiol 18(2):129-138, 2013). The recently published ATTRACT trial (Acute Venous Thrombosis Thrombus Removal with Adjunctive Catheter-directed Thrombolysis) (Vedantham et al...

One area which has emerged as an important factor for predicting molecular profile and treatment outcomes in metastatic colorectal cancer (mCRC) is primary tumor location. The importance of molecular characteristics of colorectal cancer has been firmly established in terms of prognosis and treatment algorithms for many years. Recent studies have also suggested that molecular profiles are important in locoregional therapies as well, with some data suggesting changes in treatment algorithms based on tumor location...

INTRODUCTION: Conventionally, colonic stents are inserted with a retrograde trans-anal approach-however, stenting of right-sided or proximal transverse colon lesions may pose a challenge due to tortuosity or long distances. We report three successful cases of percutaneous antegrade colonic stenting in patients using a proximal trans-peritoneal colopexy technique. MATERIALS AND METHODS: Three patients underwent a proximal trans-peritoneal colopexy technique for antegrade colonic stent placement...

BACKGROUND AND AIMS: Hepatocellular carcinoma (HCC) in the caudate lobe is technically challenging for both radiofrequency ablation (RFA) and transarterial chemoembolization (TACE). However, each of these modalities has its strengths. This retrospective study compares the effectiveness of RFA and TACE in patients with caudate HCC within the Milan criteria. METHODS: This study was approved by institutional review board. Between November 2005 and August 2016, we retrospectively reviewed 74 patients with a single HCC ≤ 5 cm or up to three HCCs ≤ 3 cm without vascular invasion or extrahepatic metastasis who were treated with RFA (n = 43) or TACE (n = 31)...
