Proximal humerus fracture is a common arm trauma and rarely occurs with vascular injury which however is a serious complication. In this case report, we present a long segment dissection of the axillary and brachial arteries as a rare complication due to fragmented proximal humerus fracture and shoulder dislocation. An 80-year old female patient was seen at the emergency department. Radiograph examination has revealed a fragmented proximal humerus fracture besides dislocation of the head of humerus towards the axillary area...

Background The use of radial-artery grafts for coronary-artery bypass grafting (CABG) may result in better postoperative outcomes than the use of saphenous-vein grafts. However, randomized, controlled trials comparing radial-artery grafts and saphenous-vein grafts have been individually underpowered to detect differences in clinical outcomes. We performed a patient-level combined analysis of randomized, controlled trials to compare radial-artery grafts and saphenous-vein grafts for CABG. Methods Six trials were identified...

INTRODUCTION: Brachial artery aneurysms are relatively uncommon and generally due to infectious, post-traumatic or iatrogenic etiology. They seem to affect 4.5% of arteriovenous fistula. The usual manifestation is an accidental finding of a pulsatile, painless, and asymptomatic mass. Complications include sac thrombosis, thromboembolic ischaemic events, and disruption with profuse bleeding. METHODS: The aim of this study is to present a case of true brachial artery aneurysm in end-stage renal disease patient after arteriovenous fistula creation...

OBJECTIVES: Despite claims of feasibility, to date no study has examined the effect of systematic bilateral internal mammary artery (BIMA) use in a large cohort of real-world unselected patients. The CATHolic University EXtensive BIMA Grafting Study (CATHEXIS) registry was designed to assess the feasibility and safety of systematic BIMA grafting. METHODS: The CATHEXIS was a single-centre, prospective, observational, propensity-matched study. The study was supposed to include 2 arms of 500 patients each: a prospective arm and a retrospective arm...

BACKGROUND: Cardiovascular disease (CVD) is the major cause of mortality worldwide. Coronary artery disease (CAD) contributes to half of mortalities caused by CVD. The mainstay of management of CAD is medical therapy and revascularisation. Revascularisation can be achieved via coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). Peripheral arteries, such as the femoral or radial artery, provide the access to the coronary arteries to perform diagnostic or therapeutic (or both) procedures...

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether the anterolateral or the inferior wall served as a better location for the 2nd arterial graft in a 3-system coronary artery bypass grafting procedure. In total, more than 1800 papers were found, of which 6 represented the best evidence to answer the clinical question. All papers demonstrated equivalent early postoperative mortality and morbidity. The 3 largest studies comparing bilateral internal thoracic arteries showed no difference in perioperative mortality and morbidity regardless of whether the 2nd internal thoracic artery was used to graft the left or right system...

The aim of this study was to evaluate in the Wistar rat the efficacy of various autologous nerve conduits with various forms of blood supply in reconstructing a 10-mm-long gap in the median nerve (MN) under conditions of local ischemia. A 10-mm-long median nerve defect was created in the right arm. A loose silicone tube was placed around the nerve gap zone, in order to simulate a local ischemic environment. Rats were divided in the following experimental groups (each with 20 rats): the nerve Graft (NG) group, in which the excised MN segment was reattached; the conventional nerve flap (CNF) and the arterialized neurovenous flap (ANVF) groups in which the gap was bridged with homonymous median nerve flaps; the prefabricated nerve flap (PNF) group in which the gap was reconstructed with a fabricated flap created by leaving an arteriovenous fistula in contact with the sciatic nerve for 5 weeks; and the two control groups, Sham and Excision groups...

Various methods have been reported to treat forearm nonunions with good results. However, in the presence of infection, inadequate vascularity of surrounding tissues, or failed prior grafts, vascularized bone grafts are a valid alternative. We describe the surgical technique to obtain distal radius vascularized bone graft pedicled on the radial artery (RA) and its clinical application in 1 case of an ulnar nonunion. We studied the surgical technique in 12 freshly injected cadavers. In the distal forearm, the RA provides several periosteal branches to supply the distal radius metaphysis...

BACKGROUND AND AIMS: The lungs participate in the modulation of the circulating inflammatory factors induced by coronary artery bypass grafting. We investigated whether aprotinin-which has been suggested to interact with inflammation-influences lung passage of key inflammatory factors after coronary artery bypass grafting. MATERIAL AND METHODS: A total of 40 patients undergoing coronary artery bypass grafting were randomized into four groups according to aprotinin dose: (1) high dose, (2) early low dose, (3) late low dose, and (4) without aprotinin...

BACKGROUND: The multiarterial grafting survival advantage noted in the overall population undergoing coronary artery bypass grafting is not well defined in the obese. We investigated the early to late survival effects of the radial artery in left internal thoracic artery-based multiarterial bypass grafting (radial artery-multiarterial bypass grafting) versus single arterial bypass grafting (left internal thoracic artery-single arterial bypass grafting) in obese patients. METHODS: We analyzed 15-year Kaplan-Meier survival in 6102 patients receiving primary, left internal thoracic artery-based coronary artery bypass grafting with 2 or more grafts divided into body mass index groups: nonobese (<30 kg/m2 ) and all-obese, comprised of mildly obese (30-35 kg/m2 ) and morbidly obese (>35 kg/m2 )...

We report the case of a 68-year-old patient, operated on in our department of a quadruple coronary bypass grafting. The grafting strategy consisted initially on harvesting the left internal thoracic artery and the left radial artery. The harvest of this latter failed because of a rare anatomical variation of the radial artery, which rose from the confluence of two branches: a superficial and a deep radial artery at the proximal third of the forearm approximately 10cm below the elbow.

BACKGROUND: Distal transradial access in the anatomical snuffbox has advantages over standard access in terms of patient and operator comfort levels and risk of ischemia. Radial artery preservation could be a relevant issue in patients requiring multiple radial artery procedures and coronary bypass with the use of a radial graft. One relevant drawback is the challenging puncture of a small and weak artery, with a steeper learning curve. AIM: The study was aimed at proving feasibility and safety of right and left transradial access in the anatomical snuffbox...

OBJECTIVE: Blood flow across the mitral valve during early left ventricular (LV) filling produces a 3-dimensional rotational fluid body, known as a vortex ring, that enhances LV filling efficiency. Diastolic dysfunction is common in elderly patients, but the influence of advanced age on vortex formation is unknown. The authors tested the hypothesis that advanced age is associated with a reduction in LV filling efficiency quantified using vortex formation time (VFT) in octogenarians undergoing coronary artery bypass graft (CABG) surgery...

Percutaneous coronary intervention (PCI) of mammary artery bypass grafts through a trans-radial (TR) approach can present unique challenges, including coaxial vessel engagement of the guiding catheter, adequate visualization of the target lesion, sufficient backup support for equipment delivery, and the ability to reach very distal lesions. The GuideLiner catheter, a rapid exchange monorail mother-in-daughter system, facilitates successful interventions in such challenging anatomy. We present a case of a patient undergoing PCI of a right internal mammary artery (RIMA) graft via TR access in whom the graft could not be engaged with any guiding catheter...

INTRODUCTION    The excess pressure-time integral (excess PTI) and reservoir pressure-time integral(reservoir PTI) are new measures derived from blood pressure (BP) waveform decomposition. Thesemarkers predict cardiovascular (CV) complications and are associated with target organ  damage inpa tients on antihypertensive treatment or those with chronic and acute heart failure. OBJECTIVES    We investigated whether reservoir PTI or excess PTI predict future CV events (death, stroke, myocardial infarction [MI]) in patients with acute coronary syndrome (ACS) and reduced ejection fraction (EF)...
