BACKGROUND: The ongoing shortage of donor livers for transplantation and the increased use of marginal livers necessitate the development of accurate pretransplant tests of viability. Considering the importance energy status during transplantation, we aimed to correlate peritransplant energy cofactors to posttransplant outcome and subsequently model this in an ex vivo setting. METHODS: Sequential biopsies were taken from 19 donor livers postpreservation, as well as 30 min after portal venous (PVR) and hepatic arterial reperfusion (HAR) and analyzed by LC-MS for energetic cofactors (ATP/ADP/AMP, NADH/NAD, NADPH/NADP, FAD, GSSG/GSH)...

BACKGROUND: Avulsion of the scalp is a rare but severe trauma and challenging to the reconstructive surgeon. It poses not only physical concussion but also significant persisting psychological distress to the patients. METHODS: Medical records from 5 patients who suffered scalp avulsion were reviewed retrospectively. The following data and methods were assessed: age, number of vessels repaired, method of replantation, vein grafts required, blood transfusion, ischemia time, total operating time, and percentage of scalp survival...

In renal transplant, multiple renal arteries in a donor require meticulous vascular reconstruction for successful allograft function in the recipient. Presence of more than 4 renal arteries is usually considered to be a relative contraindication for proceeding with renal donation. We report a living-donor renal transplant procedure where preoperative radiologic imaging of the donor showed 3 left renal arteries. Two additional arteries were identified intraoperatively. All 5 arteries were reconstructed during the back-table procedure, and the allograft was implanted in the recipient...

INTRODUCTION: Kidney transplantation (KT) is the preferred treatment for patients with end-stage renal disease (ESRD). To reduce the morbidity of the open surgery, a robotic-assisted approach has been recently introduced. Our aim is to evaluate surgical and functional results on 17 cases of robotic-assisted kidney transplantation (RAKT) performed at the same institution. MATERIALS AND METHODS: From July 2015 to June 2016, we performed 17 cases of RAKT from living donors in pre-emptive patients, who underwent laparoscopic nephrectomy...

Endothelial dysfunction and inflammation are key mechanisms of vascular disease. We hypothesised that heterogeneity of monocyte subpopulations may be related to the development of vascular dysfunction in coronary artery disease (CAD). Therefore, we examined the relationships between monocyte subsets (CD14(++)CD16(-) "classical - Mon1", CD14(++)CD16(+) "intermediate - Mon2" and CD14(+)CD16(++) "nonclassical - Mon3"), endothelial function and risk factor profiles in 130 patients with CAD undergoing coronary artery bypass grafting...

Assigned the universe of knowledge Ω as composed by one target and two exogenous signals, the conditional joint transfer entropy (CJTE), assessing the amount of information jointly transferred from the two sources to the target that can be uniquely linked to one of the two sources, was found useful to study cardiovascular control. We propose the assessment of CJTE from systolic arterial pressure (SAP) and respiration (R) to heart period (HP) conditioned on R (CJTESAP, R→HP|R) along the baroreflex, and from HP and R to SAP conditioned on R (CJTEHP, R→SAP|R) along the feedforward mechanical pathway, in 134 patients undergoing coronary artery bypass graft surgery before (PRE) and after (POST) the induction of general anesthesia...

The aim of this paper was to analyze the P-wave variability over time in patients suffering from Atrial Fibrillation (AF). Behind some time-domain and morphological features of the P-wave template, two novel indexes of P-wave variability have been estimated: one based on the cross-correlation coefficients among the P-waves (Correlation Index, CI), and one associated to variation of P-waves amplitude (Amplitude Index, AI). These indexes were estimated in two experimental models: patients suffering from persistent AF respect to control subjects and patients developing post-operative AF (POAF) after coronary artery bypass grafting respect to patients without POAF...

The physical and mental needs of patients with coronary heart disease are affected by both the disease and the heart surgery in different ways. Such diverse needs require different approaches. A continuous care model, which involves orientation, sensitization, control, and evaluation, may favorably influence patient outcomes following coronary artery bypass grafting (CABG). We were interested to ascertain whether a continuous care model might lead to improved quality of life, compared with a routine care model, in patients undergoing CABG...

BACKGROUND: Several proximal anastomosis devices have been developed to shorten the time required for a proximal anastomosis and to avoid aortic cross-/side-clamping during coronary artery bypass grafting. This study retrospectively examined the patency of saphenous vein grafts (SVGs) using the PAS-Port System (Cardia Inc, Redwood City, CA). METHODS: From 2004 to 2014, 451 patients underwent coronary artery bypass graft operations requiring at least 1 proximal anastomosis using a PAS-Port device...

OBJECTIVE: The Kidney Disease Outcome Quality Initiative and Fistula First Breakthrough Initiative call for the indiscriminate creation of arteriovenous fistulas (AVFs) over arteriovenous grafts (AVGs) without providing patient-specific criteria for vascular access selection. Although the U.S. AVF rate has increased dramatically, several reports have found that this singular focus on increasing AVFs has resulted in increased AVF nonmaturation/early failure and a high prevalence of catheter dependence...

BACKGROUND: Abdominal aortic aneurysms (AAAs) are a vascular condition with significant risk attached, particularly if they rupture. It is, therefore, critical to identify and repair these as an elective procedure before they rupture and require emergency surgery. Repair has traditionally been an open surgical technique that required a large incision across the abdomen. Endovascular abdominal aortic aneurysm repairs (EVARs) are now a common alternative. In this procedure, the common femoral artery is exposed via a cut-down approach and a graft introduced to the aneurysm in this way...

BACKGROUND: Aprotinin appears to be more efficacious than lysine analogues to reduce bleeding and transfusion of blood products in high-transfusion-risk cardiac surgical patients. However, in isolated coronary artery bypass graft (CABG) surgery, the results from head-to-head trials remain less conclusive. OBJECTIVE: Our objective was to compare the efficacies and safety of aprotinin and tranexamic acid (TXA) in patients undergoing isolated on-pump CABG. DESIGN: A large multicentre before-and-after study pooling individual data from published trials and unpublished data from three other databases...

BACKGROUND: The influence of coronary artery disease (CAD) on clinical and echocardiographic outcomes after transcatheter aortic valve replacement (TAVR) is still controversial. We sought to evaluate the impact of CAD severity as measured by the SYNTAX score (SS) on patients undergoing TAVR. METHODS AND RESULTS: A total of 377 patients who underwent TAVR in 2 high-volume centers in North America were included in our retrospective analysis. A blinded angiographic core laboratory calculated the SS on all available coronary angiograms with the use of quantitative coronary analysis...

Essential thrombocythemia (ET) is a myeloproliferative disorder characterized by persistent thrombocytosis (>450 × 10(9)/L). Patients with ET are at risk for thrombotic or hemorrhagic complications especially during cardiovascular operations. We discuss a patient with ET requiring coronary artery bypass grafting with a presenting platelet count of 1631 × 10(9)/L. Platelet reduction with an intraoperative autologous transfusion technique decreased the platelet count to 758 × 10(9)/L before initiation of cardiopulmonary bypass...

We present the case of a type AB thymoma in a 69-year-old man with previous coronary artery bypass grafting (CABG) in whom angiography revealed a left internal mammary artery graft supplying blood flow to a thymic neoplasm, which simultaneously occluded the graft. This required a redo sternotomy, lysis of pericardial adhesions, complete thymectomy, and redo one vessel off-pump CABG. This case seeks to sensitize physicians to the possibility of coronary adverse events in patients with a previous CABG in the setting of management of mediastinal neoplasms, and it presents the novel findings on cardiac imaging associated with this case...

Bioactive coatings which support the adhesion of late-outgrowth peripheral blood endothelial progenitor cells (EOCs) are actively being investigated as a means to promote rapid endothelialization of "off-the-shelf," small-caliber arterial graft prostheses following implantation. In the present work, we evaluated the behavior of EOCs on thromboresistant graft coatings based on the collagen-mimetic protein Scl2-2 and poly(ethylene glycol) (PEG) diacrylate. Specifically, the attachment, proliferation, migration, and phenotype of EOCs on PEG-Scl2-2 hydrogels were evaluated as a function of Scl2-2 concentration (4, 8, and 12 mg/mL) relative to human umbilical vein endothelial cells (HUVECs)...
