BACKGROUND: Good results have been reported for angioplasty and stenting of post-thrombotic lesions of the iliac and proximal femoral veins. If lesions at the origin of the superficial femoral and profunda veins are stented, the intraluminal synechiae can be pushed against the orifices of inflow vessels, potentially decreasing stent inflow. Surgical disobliteration of the common femoral vein (endophlebectomy) has been suggested to mitigate this problem. Because of a temporary increase in thrombogenicity, this procedure may be accompanied by arteriovenous fistula creation...

PURPOSE: Balloon angioplasty is the standard treatment for dysfunctional hemodialysis fistulas, but angioplasty response of stenotic lesions located in different segments of the dialysis circuit has not been explicitly evaluated. The purpose of this study is to describe the distribution of stenotic lesions in the most common types of arteriovenous fistulas and to investigate the response to balloon angioplasty of stenotic lesions located in various segments of the fistula circuit. MATERIALS AND METHODS: This single-center, retrospective study was approved by the Institutional Review Board...

OBJECTIVE: Peripheral venous reconstruction surgery may be necessary for appropriate oncologic resection; however, the operative approach and surgical outcomes are not well described. We report our experience with these complex reconstructions to identify best practice. METHODS: We retrospectively reviewed all adult patients who underwent peripheral vein reconstruction for tumor resection at Mayo Clinic, Rochester (2000-2015). Patients were classified into three subgroups by the location: iliac (IL), lower extremity (LE), and upper extremity (UE)...

AIMS: Recent frequency-domain optical coherence tomography studies showed that a complete removal of thrombotic materials is rarely achieved after percutaneous coronary interventions for ST segment elevation myocardial infarction. Residual intrastent thrombus can embolize distally leading to microcirculatory injury. The aim was to find a possible correlation between residual intrastent thrombus and angiographic indexes of myocardial reperfusion. METHODS: The population consisted of 128 ST segment elevation myocardial infarction patients enrolled in the COCTAIL II trial...

PURPOSE: To investigate whether accessory vein embolization (AVE) improves long-term performance of salvaged nonmaturing arteriovenous fistulae (AVFs). MATERIALS AND METHODS: This retrospective review included 72 patients who underwent percutaneous balloon angioplasty for salvage of nonmaturing AVFs between 2008 and 2014. AVE was performed on 32 patients between 2008 and 2011 (mean age, 59 y [range, 33-85 y]; men, n = 21; women, n = 11; upper arm, n = 17; forearm, n = 15), whereas the procedure was not performed on 40 patients after 2011 (mean age, 62 y [range, 28-85 y]; men, n = 26; women, n = 14; upper arm, n = 26; forearm, n = 14)...

Cerebral vasospasm associated with hyperthyroidism has not been reported to cause cerebral infarction. The case reported here is therefore the first of cerebral infarction co-existing with severe vasospasm and hyperthyroidism. A 30-year-old woman was transferred to our hospital in a stuporous state with right hemiparesis. At first, she complained of headache and dizziness. However, she had no neurological deficits or radiological abnormalities. She was diagnosed with hyperthyroidism 2 months ago, but she had discontinued the antithyroid medication herself three days ago...

We evaluated whether primary percutaneous coronary intervention (pPCI) during off-hours is related to an increased incidence of contrast-induced nephropathy (CIN). We retrospectively analyzed the incidence of CIN mortality among 2552 patients with consecutive ST-segment elevation myocardial infarction treated with pPCI during regular hours (weekdays 8:00 am to 5:00 pm) and off-hours (weekdays 5:01 pm to 7:59 am, weekends and holidays). Patients in the off-hour group were more frequently admitted with acute heart failure symptoms (16...

AIMS: To perform a meta-analysis investigating the outcomes of patients undergoing percutaneous revascularization with drug-coated balloon (DCB) angioplasty because of femoropopliteal in-stent restenosis (ISR). METHODS AND RESULTS: We searched scientific databases for studies of DCB angioplasty for femoropopliteal ISR. The primary outcome was target lesion revascularization (TLR). The main secondary outcome was recurrent ISR. Other outcomes of interest were Rutherford class (RC) improvement, ankle-brachial index (ABI) and death...

Mexico has been positioned as the country with the highest mortality attributed to myocardial infarction among the members of the Organization for Economic Cooperation and Development. This rate responds to multiple factors, including a low rate of reperfusion therapy and the absence of a coordinated system of care. Primary angioplasty is the reperfusion method recommended by the guidelines, but requires multiple conditions that are not reached at all times. Early pharmacological reperfusion of the culprit coronary artery and early coronary angiography (pharmacoinvasive strategy) can be the solution to the logistical problem that primary angioplasty rises...

Prognostic relevant pathways of leukocyte involvement in human myocardial ischemic-reperfusion injury are largely unknown. We enrolled 136 patients with ST-elevation myocardial infarction (STEMI) after primary angioplasty within 12 h after onset of symptoms. Following reperfusion, whole blood was collected within a median time interval of 20 h (interquartile range: 15-25 h) for genome-wide gene expression analysis. Subsequent CMR scans were performed using a standard protocol to determine infarct size (IS), area at risk (AAR), myocardial salvage index (MSI) and the extent of late microvascular obstruction (lateMO)...

BACKGROUND AND OBJECTIVES: Subintimal angioplasty is a common treatment choice for chronic total occlusions (CTO) in the iliac and femoropopliteal arteries. This article describes the technical aspects and early outcomes of two different re-entry devices and comparison with manual re-entry technique. SUBJECTS AND METHODS: A retrospective review of 61 patients (re-entry group) treated with Outback or Pioneer Plus catheters was carried out. A matched cohort of patients (n=62) who underwent lower extremity interventions without the use of re-entry devices (manual re-entry group) were also analyzed (overall 123 patients were analyzed)...

BACKGROUND: Primary angioplasty with immediate stenting (IS) is the gold standard for ST-segment elevation myocardial infarction (STEMI). Deferred stenting (DS) has been proposed to limit periprocedural complications, and may influence stent size because of thrombus and spasm alleviation. AIM: We sought to study the effect of DS on stent size. METHODS: Over the study period, 258 patients underwent primary angioplasty for STEMI (DS, n=84; IS, n=174)...

BACKGROUND: The extent of coronary disease affects clinical outcomes and may predict the effectiveness of coronary revascularization with either coronary artery bypass graft (CABG) surgery or percutaneous coronary intervention (PCI). The SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) score quantifies the extent of coronary disease. OBJECTIVES: This study sought to determine whether SYNTAX scores predicted outcomes and the effectiveness of coronary revascularization compared with medical therapy in the BARI-2D (Bypass Angioplasty Revascularization Investigation 2 Diabetes) trial...

BACKGROUND: Critical limb ischemia (CLI), despite revascularization, may result in minor or major amputations with devastating psychological effects and a negative impact on patient survival. Randomized clinical trials demonstrated that drug-eluting stents improve 1-year primary patency and decrease target lesion revascularization, compared to standard angioplasty and bare-metal stents, in patients with short occlusive below-the-knee lesions. OBJECTIVES: This prospective clinical study was designed to evaluate if one straight-line flow revascularization to the foot, using Xience-Prime Everolimus-Eluting Stent (EES), is an effective treatment of patients in Rutherford-Becker category 4 to 5 with distal popliteal and proximal tibial arteries long occlusive lesions up to 10 cm...
