BACKGROUND: Adventitial cystic disease (ACD) is an unusual arteriopathy; case reports and small series constitute the available literature regarding treatment. We sought to examine the presentation, contemporary management, and long-term outcomes using a multi-institutional database. METHODS: Using a standardized database, 14 institutions retrospectively collected demographics, comorbidities, presentation/symptoms, imaging, treatment, and follow-up data on consecutive patients treated for ACD during a 10-year period, using Society for Vascular Surgery reporting standards for limb ischemia...

OBJECTIVES: The radial artery (RA) is often used as a second arterial conduit in preference to the right internal thoracic artery in obese patients undergoing coronary artery bypass grafting (CABG) to minimise the risk of sternal wound complication. However, obesity has been found to promote RA vasoreactivity and early atherosclerotic degeneration, which may compromise graft patency when used in patients having CABG. Therefore, we investigated the effect of the RA as a second conduit compared with the saphenous vein (SV) on long-term survival in obese and non-obese patients undergoing first-time CABG...

AIMS: The purpose of this study was to assess the incidence and predictors of graft failure prior to discharge. Multi-slice computed tomography has the ability to evaluate graft patency in a non-invasive way. METHODS AND RESULTS: Of 145 consecutive patients who were screened, 73 were included in the study (78% male, mean age 65 years). A total of 206 grafts were analysed (2.8±0.9 grafts/patient). Of the 206 grafts, 126 were venous, 72 were left internal mammary, five were right internal mammary and three were radial grafts...

OBJECTIVES: We conducted propensity score matching to determine whether the use of the right internal thoracic artery (RITA) confers a survival advantage when compared with the radial artery (RA) as second arterial conduit in coronary artery bypass grafting. METHODS: The study population included a highly selected low-risk group of patients who received the RITA (n = 764) or the RA (n = 1990) as second arterial conduit. We obtained 764 matched pairs that were comparable for all pretreatment variables...

BACKGROUND: Transradial catheterisation is known to be associated with occlusion of the radial artery with an estimated incidence of 2-10% (1). There are very few studies looking at the patency of radial artery as a bypass graft after utilisation for catheterisation. METHODS: We conducted a retrospective review of patients undergoing coronary artery bypass grafting (CABG) utilising a radial artery graft. RESULTS: Long term patency rates were 59% in radial artery grafts utilised for catheterisation prior to CABG, compared to 78% if it were not (p= 0...

AIM: To evaluate the abnormalities and variations of the arterial system of upper extremities and superficial palmar arch with computed tomography angiography and to guide the clinician during this procedure. METHODS: A total of 156 upper extremities of 78 cases were retrospectively analyzed using computed tomography angiography. The study was approved by the local ethics committee of the hospital. From the analysis of the computed tomography angiography images, the following information was recorded; the diameters and abnormalities of radial, ulnar and brachial arteries in both upper extremities, the presence of atherosclerotic changes or stenosis in these arteries, whether the superficial palmar arch was complete or incomplete, and arterial dominance...

BACKGROUND: Nonunion of the scaphoid as a result of proximal fractures, failed surgical reconstruction, and especially avascular fragment necrosis are possible indications of vascularized bone grafts. Various techniques of vascularized (pedicled and free) grafts have been described. Pedicled grafts from the direct vicinity of the wrist provide several benefits. Harvest-site morbidity is reduced and preserved graft perfusion, without the need for blood vessel anastomosis, may lead to an improved consolidation...

BACKGROUND: Left ventricular (LV) dysfunction after orthotopic heart transplantation (OHT) is multifactorial and can be an indicator of graft rejection or coronary artery vasculopathy. Analysis of rotational mechanics may help in the early diagnosis of ventricular dysfunction. Studies describing the left ventricular rotational strain in children after OHT are lacking. It is important to establish the baseline rotational mechanics in pediatric OHT to pursue further studies in this population...

Regulation of the growth of vascular endothelial cells (ECs) and smooth muscle cells (SMCs) with artificial vascular grafts at vascularization is well-known to regenerate functional blood vessels for treating cardiovascular disease; however, little research has been published on this subject. Here, a novel polymer vascular graft is presented, whose inner surface contains an assembled circular microgroove pattern decorated with a combination of concentric circular microgrooves and radial, straight microgrooves inspired by the orientation of SMCs and ECs in natural tissues...

We describe the use of a composite flap composed of a sural neurofasciocutaneous flap and a vascularized peroneus longus tendon for the reconstruction of severe composite forearm tissue defects in a patient. A 43-year-old man had his left arm caught in a conveyor belt resulting in a large soft-tissue defect of 18 × 11 cm over the dorsum forearm. The extensor carpi radialis, superficial radial nerve, and radial artery were severely damaged. A free neurofasciocutaneous composite flap measuring 16 × 11 cm was outlined on the patient's left lower leg to allow simultaneous skin, tendon, nerve, and artery reconstruction...

BACKGROUND: As arterial myocardial revascularization is proved to provide great results, radial artery use as a graft and its consequences remain an important issue. OBJECTIVES: The aim of the study was to evaluate how patients assess their forearm and hand function after radial artery harvest for coronary artery bypass grafting (CABG). METHODS: 50 patients (mean age 52.2 ± 7.4 years) who underwent CABG at least 6 months (median follow up 11...

The radial artery (RA) is a commonly used conduit for coronary artery bypass grafting, and recent studies have demonstrated that it provides superior long-term patency rates to the saphenous vein in most situations. In addition, the RA is also being used with increasing frequency as the access point for coronary angiography and percutaneous coronary interventions. However, there has been concern for many years that these transradial procedures may have a detrimental impact on the function of RA grafts used in coronary artery bypass grafting, and there is now comprehensive evidence that such interventions cause morphologic and functional damage to the artery in situ...

Saphenous vein graft aneurysms are rare but are potentially fatal and their optimal management is not clearly established. Herein, we report a case of a saphenous vein graft aneurysm that was successfully treated with surgical intervention, including aneurysmal resection and re-grafting. The aneurysm, detected 36 years after coronary artery bypass grafting, was located at the proximal part of the saphenous vein graft to the posterolateral branch; the flow of the left anterior descending coronary artery was limited due to compression of the left internal thoracic artery by the adjacent aneurysm...

Giant serpentine and dolichoectatic aneurysms (GSDAs) are a small subgroup of intracranial aneurysms that often have poor clinical outcomes and are hardly to be treated by either conservative or endovascular management. We assessed seven patients who underwent internal maxillary artery bypass using radial artery graft interposition followed by parent artery occlusion to treat GSDAs. Intraoperative Doppler ultrasonography was used to assess the patency of the graft. CT angiogram or DSA were used postoperatively...

PURPOSE: The selection of optimal grafts for the right coronary artery remains controversial. This study aims to evaluate the short- and long-term results of radial artery (RA) grafts and saphenous vein grafts (SVGs) to the right coronary artery. METHODS: We reviewed, retrospectively, isolated coronary artery bypass grafts, placed between 1997 and 2007, and compared the long-term results of patients who received RA (n = 110) grafts with those of patients who received SVGs (n = 264) using propensity-score matching for risk...

BACKGROUND: There is a lack of evidence for the choice of the second conduit in coronary surgery. The radial artery (RA) is a possible option, but few data on very-long-term outcomes exist. OBJECTIVES: This study describes 20-year results of RA grafts used for coronary artery bypass grafting and the effects of RA removal on forearm circulation. METHODS: We report the results of the prospective 20-year follow-up of the first 100 consecutive patients who received the RA as a coronary bypass conduit at our institution...
