Surgical revascularization of the lower extremity using bypass grafts to distal target arteries is an established, effective therapy for advanced ischemia. Recent multicenter data confirm the primacy of autogenous vein bypass grafting, yet there remains significant heterogeneity in the utilization, techniques, and outcomes associated with these procedures in current practice. ...

Thrombogenic occlusion, at the anastomotic microvessels, contributed impaired blood flow to flap failure. The effect of an orally active low molecular weight heparin (LMWH) derivative conjugated with deoxycholic acid (DOCA) on the patency of anastomosis of the crushed rat artery was investigated, expecting its antithrombogenic effect. 60 Femoral arteries of ...

The superiority of left internal thoracic artery (LITA) grafting to the left anterior descending artery (LAD) is well established. Patency rates of 80%-90% have been reported at 10-year follow-up. However, the superiority of sequential LITA grafting has not been proven. Our aim was to compare patency rates after sequential LITA ...

The impact of gender on outcome after coronary artery bypass grafting (CABG) is controversial. The aim of this study was to compare the differences of clinical and angiographic outcomes between female and male patients after CABG. The records of 954 patients who underwent isolated CABG between 2004 and 2009 were ...

In redo coronary artery bypass grafting (CABG), repeat median sternotomy is a routine approach when the graft to the left anterior descending artery (LAD) is occluded. However, it is important to avoid injury to the patent graft to LAD during repeat sternotomy. We retrospectively reviewed our cases to assess our ...

Some abdominal aortic aneurysms bridged with a minimally invasively introduced stent graft prosthesis increase in size without any diagnosable evidence of endoleakage (endotension). There are three possible pathways proposed through which undetectable low rates of blood flow may cause an aneurysm sac to be refilled: through the thrombus at the ...

Coronary artery bypass grafting (CABG) is a well-established therapy for patients with multivessel coronary artery disease, with excellent short- and medium-term results. This is best illustrated by studies comparing percutaneous coronary interventions (PCIs) with CABG surgery, where CABG continues to offer better event-free survival. However, there has been increasing concern ...

Graft occlusion is a well-documented etiology for arteriovenous fistulae failure. However, there is little morphologic information elucidating why synthetic vascular grafts fail. The purpose of this study was to examine the tissue responses occurring within and adjacent to explanted polytetrafluoroethylene grafts that were utilized during cardiovascular procedures and subsequently removed. ...

Composite sequential femoro-popliteal-distal bypass is a valuable option for treatment of critical limb ischemia when autogenous vein is limited and an isolated popliteal or distal arterial segment exists. We report a modified technique for composite sequential bypass and the results with its use over a 14-year period. Twenty-five modified composite ...

The 6-minute walk test (T6) is used to assess cardiopulmonary diseases due to its prognosis capacity, easy performance and reproducibility. Pulmonary hypertension (PH) is defined and classified as a hemodynamic consequence leading to increased pulmonary arterial pressure and may result in right ventricular failure and consequent death. This case reports ...

Sequential anastomoses in coronary artery bypass grafting (CABG) offer theoretical advantages including increased graft flow and more complete revascularisation. However, published studies concerning the safety and efficacy of this technique are not definitive. The objective of this study was to assess the effect of sequential anastomoses on outcomes following CABG. ...

Accelerated intimal hyperplasia (IH) is an important cause of morbidity and mortality in patients with atherosclerotic vascular disease treated with bypass vein grafts. We used an interposition vein graft model to determine the source of neointimal cells in a clinically relevant large animal model. Jugular vein segments from sex-mismatched, MHC-in-bred ...

Cerebral bypass procedures in the posterior circulation are difficult to perform and are considered to be high-risk surgery. Venous grafts, like that formed using the saphenous vein (SV), are simple to obtain without posing a high risk of morbidity. The main disadvantage of these high-flow grafts is the mismatch in ...

On-pump total arterial grafting is associated with improved long-term outcomes compared to conventional grafting using left internal thoracic artery and saphenous vein grafts, but there are no data to confirm the same for off-pump total arterial grafting. We assessed the impact of off-pump total arterial grafting on medium-term outcomes. From ...

Sutureless anastomosis devices have been developed to facilitate arterial bypass surgery on the beating heart. However, these devices can significantly alter the hemodynamics at the end-to-side anastomosis and in the host artery, leading to the formation of thrombus or/and intimal hyperplasia (IH). In this study, a numerical analysis was performed ...

For coronary artery bypass grafting, the use of free gastroepiploic artery is unpopular because of its tendency to vasospasm. We assessed the en-bloc free gastroepiploic artery graft, which has the gastroepiploic vein anastomosed to the right atrial appendage to prevent graft spasm, and compared it to the skeletonized free gastroepiploic ...

In this paper, the hemodynamics in a three-dimensional out-of-plane sequential bypass graft model is first investigated. Based on the advantageous flow characteristics observed within the side-to-side (STS) anastomosis in the sequential bypass graft simulation, a new CABG coupled-sequential anastomosis configuration is designed, entailing coupled STS and end-to-side (ETS) anastomotic components. ...

We describe a modified technique of anastomosis between dissected aortic stump and a Dacron tube graft (Sulzer Vascutek, Renfrewshire, Scotland) with the aim of minimizing suture line complications. After a stented graft was implanted into the stump or a Teflon felt strip (C.R. Bard, Inc, Tempe, AZ) was circumferentially placed ...

We report the case of a symptomatic spontaneous leak of a biosynthetic graft (Omniflow (II) treated endovascularly with a stentgraft. Potential degeneration of biosynthetic grafts with aneurysm formation is a well known problem with a reported incidence of up to 7 %. Implantation of a stentgraft for treatment of a ...

Acute aortofemoral graft occlusion is often effectively treated with endovascular therapy but a substantial proportion of patients experience failure or complications of this therapy, and most of them require definitive surgery for the underlying inflow, outflow, or graft disease. We describe a case of an aortofemoral graft occlusion that was ...

The Cabrol procedure is one of several techniques used for re-implantation of a coronary artery. After replacement of the ascending aorta and aortic valve using a composite graft, second Dacron tube grafts are used for anastomosis between the ascending aortic graft and the coronary arteries. Ostial stenosis is one of ...

A prospective analysis was made on 11 patients who received a brachial artery-external/internal jugular polytetrafluoroethylene jump graft for hemodialysis access. The procedure was chosen because of exhaustion of the veins in the upper extremity owing to previous multiple failed fistulas or grafts. In two patients, the procedure failed after several ...

Prosthetic vascular bypass grafting is associated with poor long-term patency rates. Herein, we report on the mid-term performance of expanded polytetrafluoroethylene (ePTFE) vascular grafts modified with a citric acid-based biodegradable elastomer. Through a spin-shearing method, ePTFE grafts were modified by mechanically coating a layer of poly(1,8 octanediol citrate) (POC) onto ...

Arteriovenous grafts (AVGs) for hemodialysis have a high failure rate, often due to the development of stenosis at the graft-to-vein anastomosis. Angioplasty (PTA) has been used for over two decades to treat AVG stenosis, with good technical success but limited AVG patency. Results of a prospective multi-center randomized trial, comparing ...

For the nephrologist and surgeon, maintaining vascular access is a significant challenge in hemodialysis (HD), because the portal is vulnerable to infection, stenosis, and thrombus. Vascular access options for HD include the placement of arteriovenous (AV) fistulas, AV grafts, and double-lumen, cuffed central vein catheters. Catheter use is generally associated ...
