PURPOSE: To assess a novel tibial artery perfusion score (TPS) for predicting limb salvage in critical limb ischemia (CLI) patients undergoing percutaneous vascular intervention (PVI). PATIENTS AND METHODS: A consecutive cohort of 115 CLI patients undergoing PVI in 144 limbs from 2011 to 2016 was analyzed. TPS comprised a 27-point scale based on: (1) patent tibial vessels following PVI, (2) severity of calcification of the tibial arteries, (3) presence of an intact pedal arch following intervention, (4) whether or not revascularization was direct or indirect based on the target angiosome, (5) presence of angiosome blush at the completion of index intervention...

PURPOSE: To determine the effects of prostatic artery embolization (PAE) on prostatic elasticity as assessed by Ultrasound Elastography (US-E), as well as to describe the feasibility and role of US-E as a novel tool in both pre- and post-PAE evaluation. MATERIALS AND METHODS: This is a prospective, single-center investigation that included eight patients undergoing PAE for treatment of lower urinary tract symptoms (LUTS) attributed to benign prostate hyperplasia (BPH)...

Ischemic neuropathy is an exceedingly rare complication after peripheral artery embolization. We report a case of ischemic damage to the tibial and peroneal nerve after embolization of the vasa nervorum that served as feeding collaterals to a surgically excluded popliteal artery aneurysm.

OBJECTIVE: To report the technique of hydrodissection of the gallbladder bed, in order to separate the gallbladder wall from the liver surface during microwave ablation of liver malignancies located in segment V. MATERIALS AND METHODS: Between January 2018 and March 2018, percutaneous hydrodissection of the gallbladder fossa was performed during four microwave ablation procedures in three patients (One patient was treated twice for the same lesion, making a total of four procedures for three lesions...

OBJECTIVES: The aim of this study was to evaluate the clinical course and vascular remodeling of spontaneous isolated intramural hematoma of the superior mesenteric artery (SIHSMA) after treatment. METHODS: In this retrospective study, 24 consecutive patients with SIHSMA admitted from January 2009 through December 2016 were included in this study. The clinical characteristics, type and location of the dissection, clinical outcome and vascular remodeling were analyzed retrospectively...

BACKGROUND: Percutaneous vertebroplasty (PV) is an alternative option to treat pain after an osteoporotic vertebral compression fracture (OVCF). Controversy exists as to whether PV increases the risk of new OVCFs or prevents further vertebral height loss in treated levels. We assessed both during 1-year follow-up in patients with acute OVCF randomised to PV or a sham procedure. METHODS: VERTOS IV is a prospective, multicentre, randomised controlled trial comparing PV with sham therapy in 180 patients...

PURPOSE: To evaluate long-term primary and secondary patency results of drug-eluting balloon angioplasty for the treatment of juxta-anastomotic stenoses in distal radiocephalic arteriovenous fistulas. MATERIALS AND METHODS: Thirty-eight patients with juxta-anastomotic stenotic distal radiocephalic arteriovenous fistulas who underwent endovascular treatment with drug-eluting balloons between January 2014 and August 2016 in our interventional radiology department were included in this retrospective study...

PURPOSE: To retrospectively evaluate the short-term outcomes of lymphangiography and lymphatic embolization in the treatment of pelvic lymphocele after radical prostatectomy in patients with prostate cancer. MATERIALS AND METHODS: The data of nine, consecutive patients who underwent lymphangiography and lymphatic embolization for pelvic lymphocele after radical prostatectomy with pelvic lymph node dissection (PLND) between January 2016 and May 2018, were retrospectively reviewed...

INTRODUCTION: Proximal oesophageal stent deployment continues to provide challenges due to the proximity of the upper oesophageal sphincter and the associated subsequent complications such as globus sensation and stent migration. Patients with cervical oesophageal cancer have previously had limited stenting options available to them with a paucity of the literature describing the radiological technique for successfully placing these high-risk stents. In this paper, we present our experience using the Taewoong Niti-S CERVICAL Oesophageal Stent...

PURPOSE: The present study is a register-based observational study of an unselected consecutive patient cohort with pulmonary arteriovenous malformations (PAVMs) from a single national hereditary hemorrhagic telangiectasia and PAVM embolization center. The aim was to investigate the frequency of re-embolizations and the clinical outcome after embolization with the use of different embolization materials further, to define which PAVM morphology and size of feeding arteries that most often were re-embolized, and to estimate the clinical outcome of the patients including those that were re-embolized...

BACKGROUND: Endovascular stents are commonly used during neurointerventional procedures; however, the concomitant use of dual anti-platelet treatment (DAPT) can limit their use. There is a need to develop stent coatings that mitigate requirement for DAPT. METHODS: The hydrophilic polymer coating is a novel glycan-based multilayer polymer that inhibits platelet adhesion. After Institutional Animal Care and Use Committee approval, 18 New Zealand white rabbits (mean weight 4...

In their recently published pooled analysis of four drug-coated balloon (DCB) studies, which focused on the impact of patient and lesion characteristics on LLL at 6 months (Albrecht T et al. Cardiovasc Intervent Radiol. 2018 Dec 11. ), the authors reported slightly inaccurate 2-year mortality rates.

This systematic review and meta-analysis investigated post-biopsy manoeuvres to reduce pneumothorax following computed tomography-guided percutaneous transthoracic lung biopsy. Twenty-one articles were included with 7080 patients. Chest drain insertion rates were significantly reduced by ninefold with the normal saline tract sealant compared to controls (OR 0.11, 95% CI 0.02-0.48), threefold with the rapid rollover manoeuvre to puncture site down (OR 0.34, 95% CI 0.18-0.63), threefold with the tract plug (OR 0...

PURPOSE: To provide insight into the current use and results of ultrasound-facilitated catheter-directed thrombolysis (USAT) in patients with high-risk pulmonary embolism (PE). INTRODUCTION: Systemic thrombolysis is an effective treatment for hemodynamically unstable, high-risk PE, but is associated with bleeding complications. USAT is thought to reduce bleeding and is therefore advocated in patients with high-risk PE and contraindications for systemic thrombolysis...

Endovascular aneurysm repair (EVAR) has become the most utilized treatment for abdominal aortic aneurysms (AAA), but the presence of common iliac dilatation or aneurysm may prevent the achievement of effective distal seal and fixation. Ideal repair in these cases should involve both effective preservation of the pelvic circulation and durable exclusion of the AAA. Unilateral or bilateral internal iliac artery (IIA) preservation with iliac branch devices (IBD) is safe, feasible and effective with technical and clinical outcomes comparable to standard EVAR...

BACKGROUND AND PURPOSE: Data on the management of large vessel occlusion in patients with anterior circulation acute ischemic stroke (AIS) due to underlying intracranial stenosis are scarce. The aim of this retrospective study was to compare endovascular treatment and outcome in AIS patients with and without underlying stenosis of the M1 segment. MATERIALS AND METHODS: A total of 533 acute stroke patients with an isolated M1 occlusion who underwent mechanical thrombectomy between 02/2010 and 08/2017 were included...

BACKGROUND: Twenty percent of the patients with AAA have an aneurysm involving the common iliac arteries. Large common iliac diameter can be treated with an iliac branched device or extension of the stent graft to the external iliac artery with occlusion of the ipsilateral internal iliac artery (IIA) to prevent type 2 endoleaks. This study describes and evaluates a embolization technique using Onyx in conjunction with EVAR in aneurysms with poor landing zones in the common iliac arteries...
