Objective: To observe the effect of 5 F Tiger Ⅰ catheter shaping technique in complex coronary angiography. Methods: This study was a single-center, single-blind, randomized, parallel controlled trial and subjects were consecutively enrolled if the first coronary angiography could not be completed by 5 F Tiger Ⅰ catheterization at our department from January 2016 to June 2017 ( n= 159). The subjects were divided into 2 groups using a random number table method: 79 patients in the control group, and 6 F Judkins and Amplatz catheters were used to perform coronary angiography through the radial artery; 80 patients in the experimental group, and 5 F Tiger Ⅰ shaping technique were used to perform coronary angiography through the radial artery...

BACKGROUND:  The optimal choice of conduit and configuration for coronary artery bypass grafting (CABG) in diabetic patients remains somewhat controversial, even though arterial grafts have been proposed as superior. We attempted to clarify the role of complete arterial revascularization using the left internal thoracic artery (LITA) and the radial artery (RA) alone in "T-Graft" configuration on long-term outcome. METHODS AND RESULTS:  From 1994 to 2001, 104 diabetic patients with triple vessel disease underwent CABG using LITA/RA "T-Grafts" (Group-A)...

The purpose of the study was to elaborate an algorithm of treatment policy for post-puncture false aneurysms of the femoral artery (FAFA). The study was performed on the basis of the clinical material over 2014-2017 at the Regional Vascular Centre whose specialists have since 2017 been using the femoral arterial approach (FAA) only if the radial arteries are inaccessible for puncture or for inserting the endovascular tools and appliances. The obtained findings demonstrated that the number of coronary interventions performed with the use of the femoral arterial approach in patients presenting with acute coronary syndrome decreased from a total of 758 (100...

A femoral approach is the main access in stenting of carotid arteries, mainly due to rapid training in how to perform the procedure and a possibility of using large-diameter catheters. However, this approach is not always feasible in atherosclerosis, tortuosity of lower-limb arteries and in certain anatomical peculiarities of the aortic arch. Using a transradial approach is based on the desire to diminish the incidence rate of haemorrhagic complications in the zone of the puncture and to avoid the necessity of a long-term bed rest...

This is the first reported case of severe hand hematoma after cardiac catheterization through the distal radial artery, with the hematoma extending distally to the sheath insertion site. The distribution of the hematoma in our case is completely different compared to the hematomas observed after traditional radial catheterization, which used to extend to the forearm. Therefore, the traditional EASY classification may not apply to hematomas after catheterization through the distal radial artery.

BACKGROUND: Percutaneous coronary interventions (PCI) of old calcified saphenous vein grafts (SVGs) is challenging and is associated with a considerably high risk of adverse ischemic events in the short- and long-term as compared to native coronary arteries. We report a case in which a non-dilatable, calcified SVG lesion is successfully treated with rotational atherectomy followed by PCI and stenting with local stent delivery (LSD) technique using the Guidezilla™ guide extension catheter (5-in-6 Fr) in the "child-in-mother" fashion...

BACKGROUND: Surgical innovation is critical for the management of challenging cerebrovascular pathology. Flow-through free flaps are versatile composite grafts that combine viable tissue with a revascularization source. Neurosurgical experience with these flaps is limited. OBJECTIVE: To provide an in-depth technical description of the radial artery fascial (and fasciocutaneous) flow-through free flap (RAFF and RAFCF, respectively) for complex cerebral revascularizations...

Objectives Fingertip amputation is often encountered in emergency departments, especially in hospitals located near industrial areas. Replantation of the fingertip can be considered when the normal architecture is preserved in cases of sharp amputation. The goal of replantation is to preserve cosmesis and function, especially for the thumb because of its involvement in grasping and the key pinch. Even when microsurgical vascular anastomosis is applied, the absence of venous anastomosis along with the high rate of failure of arterial anastomosis in zone 1A fingertip amputation may lead to replantation failure...

Background and purpose The origin of migraine pain is still elusive, but increasingly researchers focus on the neuropeptides in the perivascular space of cranial vessels as important mediators of nociceptive input during migraine attacks. The parasympathetic neurotransmitters, pituitary adenylate cyclase activating peptide-38 (PACAP38) and vasoactive intestinal peptide (VIP) may be released from parasympathetic fibres and activate sensory nerve fibres during migraine attacks. Triptans are effective and well tolerated in acute migraine management but the exact mechanism of action is still debated...

BACKGROUND: This cadaveric study was designed to analyze the safety of endoscopic repair of distal biceps tendon (DBT) tears using 2 reattachment techniques. We evaluated the proximity of neurovascular structures to endoscopy portals; iatrogenic injury to neurovascular, musculotendinous, and osseous structures; and changes in compartment pressures. We hypothesized that an all-endoscopic repair of the ruptured DBT would be technically safe and the risk of iatrogenic injury would be low...

The anterior clinoidal meningiomas often engulf /encase or compress Internal Carotid artery (ICA) and its branches, Optic nerve (ON) and structures passing through superior orbital fissure (SOF). The trans-sylvain route of excising tumour poses a difficulty in exposing and safeguarding encased vessels. In addition, it may jeopardize the bulging brain and stretched veins, especially in large tumors. The objective is to present an operative video to demonstrate the technique of 'centrifugal opening' and removal of anterior clinoidal meningiomas...

INTRODUCTION: The purpose of the study is to develop an optimal TR-Band weaning strategy while minimizing vascular access site complications of hematoma or radial artery occlusion (RAO). METHODS: The trial was a randomized, prospective, single center study of 129 patients who underwent cardiac catheterization via the radial artery. Group A was an accelerated protocol in which weaning was initiated 20 min after sheath removal. Group B was an adjusted protocol, in which weaning was dependent on the amount of anti-platelet or anti-coagulation used...

OBJECTIVE: We sought to demonstrate that the combination of a local vasodilator (verapamil), modern materials, patent hemostasis, and intravenous anticoagulant only in the case of percutaneous coronary intervention, as compared to default heparin administration after sheath insertion, may optimize a combined endpoint, including radial artery oc-clusion (RAO), radial artery spasm (RAS), and access site complication. METHODS: This is a prospective, single-center, double-blind randomized trial...

PURPOSE: Radial artery occlusion flowing cardiac catheterisation has been linked to flow reduction and prolonged compression. We investigate whether these factors can be optimised following transradial cardiac catheterisation by using an accelerated band removal protocol facilitated by a haemostasis promoting pad, in combination with a patent haemostasis technique. METHODS: In this single centre prospective study, 389 consecutive patients undergoing TRA for coronary angiography or angioplasty were randomised to two haemostasis protocols: use of a Helix™ compression device alone (HC) or in combination with a haemostatic pad (StatSeal® disc) and an accelerated haemostasis protocol (AC)...

INTRODUCTION: Open reduction and internal fixation using plates is the gold standard for the treatment of displaced forearm bone fractures in adults. The ulna being subcutaneous throughout has a constant approach. However, the radius is approached from either the dorsal or the volar side. Both the dorsal and the volar approaches to the radial shaft involve meticulous dissection and preservation of important neurovascular structures. The posterior interosseus nerve is at risk in the dorsal approach and the radial artery and its branches in the volar approach...

OBJECTIVE: Mycotic aneurysms of the extremities occur infrequently but can cause severe life and limb complications. Traditional treatment typically includes debridement and revascularization, though in select patients ligation may be well tolerated. We reviewed our experience with these aneurysms treated with these two modalities. METHODS: A retrospective review of patients treated for peripheral mycotic aneurysms at one institution from January 2005 to December 2015 was performed under an Institutional Review Board-approved protocol...

PURPOSE: Transradial access (TRad) is becoming the preferred access for cardiac catheterization. The utility and safety of TRad in non-coronary and peripheral vascular interventions remains ill-defined and serves as the basis for this study. METHODS: Patients undergoing non-coronary and peripheral endovascular procedures via TRad from August 2010 to February 2013 at our institution were reviewed retrospectively. Demographic data, indications, interventions performed, sheath size, procedural outcomes and access site complications were evaluated...

Women undergoing cardiac catheterization, percutaneous coronary intervention, transcatheter aortic valve replacement, and other structural heart interventions have a significantly higher risk of vascular complications and bleeding than men, leading to significant morbidity and mortality. This review highlights the importance of recognizing female sex as a specific and independent risk factor, and focuses on mechanisms of increased risk and strategies to minimize that risk. Smaller caliber peripheral vessels, low body weight, variations in platelet reactivity, and inappropriate dosing of anticoagulant and antiplatelet agents are the currently identified mechanisms for elevated bleeding and vascular complication risk in women...

INTRODUCTION: Uterine artery (UtA) Doppler indices are one of the most commonly employed screening tests for pre-eclampsia worldwide. Abnormal indices appear to result from increased uterine vascular resistance, but anatomical complexity and lack of appropriate animal models mean that little is known about the relative contribution of each of the components of the uterine vasculature to the overall UtA Doppler waveform. Previous computational models suggested that trophoblast-mediated spiral artery remodeling has a dominant effect on the UtA Doppler waveform...
