This case series illustrates a radial access complication seen in 7 of 9 consecutive patients (age range, 44-53 y) undergoing uterine artery embolization in May and June 2017. Demonstrative images and videos identify a transient and clinically consequential skin ischemia caused by intraprocedural saline solution infusion through the occlusive radial artery sheath. All complications documented were classified as mild adverse events (class A) according to Society of Interventional Radiology criteria. Complication severity ranged from transient blanching to ischemic necrosis of the skin...

The percutaneous transradial artery approach for coronary angiography and intervention has been recognized as a safe and effective method, however, it is limited for endovascular therapy (EVT) for femoro-popliteal artery because of lack of devices with longer shaft. Herein, we report two EVT cases for superficial femoral artery disease treated with a long shaft balloon through the radial artery. Although femoro-popliteal artery intervention with this approach has several limits for available devices and technical issues, it is effective for particular patients who are impossible in EVT with femoral artery approach...

INTRODUCTION: Aerobic exercise has a favorable effect on systemic vascular function, reducing both central (large elastic artery) and peripheral (smaller muscular artery) stiffness. The effects of resistance exercise (RE) on arterial stiffness are more complex. Acute RE increases central artery stiffness while decreasing peripheral stiffness. To date, the majority of studies have been performed in predominantly male participants. PURPOSE: To examine the effect of acute RE on central and peripheral arterial stiffnesses in women, a secondary purpose was to explore the influence of cyclic changes in estrogen status across the menstrual cycle on the arterial response to acute RE...

Hand knob infarction (HKI) is a rare clinical condition which is often misdiagnosed as peripheral neuropathy. This study aimed to identify the clinical characteristics and risk factors of HKI. Nine HKI patients admitted between January 2013 and March 2016 were confirmed by magnetic resonance imaging. Their medical records were collected and analyzed. The modified Rankin Scale was used to assess clinical outcomes. Routine laboratory tests, electrocardiogram, echocardiography, cranial magnetic resonance imaging, magnetic resonance angiography, computed tomography angiography, and Doppler ultrasonography examinations were performed...

BACKGROUND: More than 90% of coronary artery bypass grafting (CABG) is performed with a single-arterial bypass graft (SABG), based on the left internal thoracic artery (ITA) with supplemental vein grafts. This practice, often justified by safety concerns with multiple-arterial grafting (MABG), defies evidence of improved late survival achieved with bilateral ITA (BITA-MABG) or left ITA plus radial artery (RA-MABG). We hypothesized that MABG and SABG are equally safe. METHODS: We analyzed The Society of Thoracic Surgeons National Database (2004 to 2015) to assess the operative safety of BITA-MABG (n = 73,054) and RA-MABG (n = 97,623) vs SABG (n = 1,334,511)...

BACKGROUND: Duplex ultrasound (DUS) mapping of the veins and arteries of the upper extremity is a well-established practice in arteriovenous fistula creation for long-term hemodialysis access. Previous publications have shown that vein diameters varying from 2 to 3 mm are predictive of success. Regional anesthesia is known to result in vasodilation and thus to increase the diameter of upper extremity veins. This study compares the sizes of veins measured by preoperative DUS mapping with those obtained after regional anesthesia to determine whether intraoperative DUS results in increased vein diameters and thus changes in the operative plan...

BACKGROUND: During transradial (TR) access, it remains unclear whether differences in baseline patients characteristics and hemostasis care impact the rate of radial artery occlusion (RAO). We sought to compare the rate of RAO after TR access with the 6 French(Fr) Glidesheath Slender (GSS6Fr, Terumo, Japan) or a standard 5 Fr sheath in Japanese and non-Japanese patients. METHODS AND RESULTS: The Radial Artery Patency and Bleeding, Efficacy, Adverse evenT (RAP and BEAT) trial randomized 1,836 patients undergoing TR coronary angiography and/or interventions to receive the GSS6Fr or the standard 5 Fr Glidesheath (GS5Fr, Terumo, Japan)...

INTRODUCTION: Mechanical thrombectomy (MT) has been widely accepted as a safe and effective treatment for acute ischemic stroke (AIS). Development of stent retriever devices has been intensively developed over the past two decades. In this study, we compared the effectiveness and safety of a new thrombectomy device with Solitaire FR for the treatment of AIS models. METHODS: Mechanical performance of stent retrievers was tested in vitro. Thrombin-induced thrombus was pre-injected into the right distal external carotid-maxillary artery in 18 dogs to create an acute thrombus occlusion model, and these animals were divided into a Tonbridge group (n=9, with Tonbridge stent Tonbridge Medical Technology) and a Solitaire group as control (n=9, with Solitaire stent, ev3 Neurovascular)...

Intracoronary acetylcholine (ACh) provocation test is useful to diagnose vasospastic angina. Although outpatient coronary angiography has been widely performed in current clinical settings, the feasibility and safety of ACh provocation test in outpatient services are unclear. A total of 323 patients, who electively underwent ACh provocation test in hospitalization and outpatient services, were included. Coronary angiography was performed after insertion of a temporary pacing electrode in the right ventricle...

BACKGROUND: Nasal reconstruction after burn injury can be challenging due to limited availability of local flaps. We present our experience of free flap reconstruction for full-thickness nasal defect after severe facial burn injury. METHODS: Between August 1998 and September 2015, six patients underwent nasal reconstruction with seven free flaps after burn injury. Among them, flame burn occurred in two patients, chemical burn in two, explosive burn in one, and contact thermal burn in one patient...

BACKGROUND: Native arteriovenous fistula (AVF) is considered the gold standard of vascular access for hemodialysis due to its longer survival, fewer complications, lower mortality and costs. Patency is important for effective dialysis treatment and this remains a challenge in nephrology. There are no well-defined prognostic factors for early and long-term AVF survival. The aim of this study was to evaluate comorbidity, analytical and ultrasound (US) variables as prognostic factors for early failure and AVF patency...

BACKGROUND Hypothenar hammer syndrome is a relatively rare disease process caused by repetitive stress or injury to the hypothenar eminence leading to chronic injury to the ulnar artery. This chronic stress (usually as a result of occupational or sport activities) may result in arterial constriction or thickening, which may lead to thrombosis or aneurysm formation. A review of current literature revealed that reports related to management of hypothenar hammer syndrome are limited. CASE REPORT A 33-year-old male without significant past medical history presented with left hand/digit pain, skin discoloration, and coolness of the hand/digits after a mechanical accident experienced 12 hours prior to presentation...

OBJECTIVE: Handgrip exercise is an emerging strategy for resting blood pressure (BP) reduction requiring minimal time and exercise effort. However, the research literature is currently limited to handgrip protocol designs predominantly prescribing sustained grip contractions, with little assessment of alternative options. Furthermore, our understanding of the utility of handgrip exercise would be strengthened by an evaluation of the physiological mechanisms driving BP reductions and an assessment of the interindividual response variability...

PURPOSE: Atrial fibrillation (AF) is associated with an increased risk for cardiovascular morbidity and mortality, not entirely explained by thromboembolism. The underlying mechanisms for this association are largely unknown. Similarly, high blood pressure (BP) increases the risk for cardiovascular events. Despite this the interplay between AF and BP is insufficiently studied. The purpose of this study was to examine and quantify the beat-to-beat blood pressure variability in patients with AF in comparison to a control group of patients with sinus rhythm...

In this article, we report two cases in which recurrent adhesive hand neuropathy with allodynia were successfully treated with radial and ulnar artery adipofascial perforator flap coverage. Treatment of recurrent neuropathy, such as recurrent carpal tunnel syndrome and re-adhesion after neurolysis using free and pedicle flaps to cover the nerves, has been reported to show good results. However, for severe painful nerve disorders, such as complex regional pain syndrome, the efficacy of this treatment was unclear...

Superficial ulnar artery (SUA) is defined as arterial variation of an ulnar artery of high origin that lies superficially in the forearm. Because an SUA may be mistaken for a superficial vein, there is a risk of arterial damage. During routine dissection of the cadaver, we incidentally detected a case of unilateral SUA in the left arm. SUA arose from the axillary artery and descended superficial to the axillary artery and median nerve. At the wrist, the SUA crossed over palmaris longus (PL) tendon from the radial side to the ulnar side...
