There is a significant variety of vascular conduits options for coronary bypass surgery. Adequate graft selection is the most important factor for the success of the intervention. To ensure durability, permeability, and bypass function, there must be a morphological similarity between the graft and the coronary artery. The objective of this review was to analyze the morphological characteristics of the grafts that are most commonly used in coronary bypass surgery and the coronary arteries that are most frequently occluded...

Myonecrosis after coronary artery bypass graft (CABG) surgery is associated with excess mortality. Tranexamic acid (TA), an anti-fibrinolytic agent, has been shown to reduce peri-operative blood loss without increasing the risk of myocardial infarction (MI); however, no large study has examined the association between TA treatment and post-CABG myonecrosis. In the MC-1 to Eliminate Necrosis and Damage in Coronary Artery Bypass Graft Surgery II trial, inverse probability weighting of the propensity to receive TA was used to test for differences among the 656 patients receiving and 770 patients not receiving TA...

Iatrogenic aortic dissection (AD) is quite a rare complication during percutaneous coronary intervention (PCI). The exact mechanism of iatrogenic AD during PCI is unknown. A standard of care in the management of iatrogenic AD is still lacking. We describe a case of an 83-year-old man, with an aortocoronary bypass graft, who underwent complex PCI with rotational atherectomy catheterization with a radial approach for a chronic right coronary artery stenosis, complicated by AD. According to our experience, retrograde dissection into the aorta during PCI can be sealed with a coronary stent that covers the coronary ostium and should be treated conservatively in most circumstances, unless complication like extension of dissection into other vessels or pericardial effusion or hemodynamic instability occurs...

Bilateral cavernous carotid aneurysms (CCAs) are often not amenable to neurosurgical clipping or endovascular coiling. Here, we report the case of a 50-year-old female who presented with a 1-year history of gradual severe headache. Preoperative angiograms revealed bilateral CCAs. Among these findings, the right giant CCA had been trapped after the external carotid artery-saphenous vein-middle cerebral artery (ECA-SV-MCA) bypass 8 years prior. Additionally, the left CCA was again trapped after the internal maxillary artery-radial artery-middle cerebral artery (IMA-RA-MCA) bypass, followed by parent artery occlusion (PAO), because of the enlargement of a 0...

Subclavian artery (SCA) perforation is a rare complication while performing SCA intervention. In our present report, a 73-year-old female, with stenosis of the left SCA and situs inversus, presented with exercise-induced left arm weakness. The SCA stenosis was treated with direct stenting with a balloon-expansible Express LD 10×25 mm stent. However, it caused iatrogenic SCA perforation and hemothorax. The perforation was sealed by endovascular repair with operator-modified Endurant II graft stent, which complicated with occlusion of left common carotid artery...

BACKGROUND: The potential survival benefit of bilateral internal thoracic artery (BITA) grafting in patients undergoing off-pump coronary artery bypass graft surgery (OPCABG) is controversial owing to the technical complexity of these operations. Our objective was to compare the outcome of patients undergoing OPCABG with BITA to the outcome of patients undergoing OPCABG with a single internal thoracic artery (SITA) and saphenous vein grafts or radial artery. METHODS: Five hundred and thirty-five consecutive patients who underwent OPCABG BITA at our institute between 2000 and 2008 were compared with 422 patients who underwent OPCABG with SITA...

BACKGROUND: Transradial coronary angiography (TRA) has been associated with increased radiation doses. We hypothesized that contemporary image noise reduction technology would reduce radiation doses in the cardiac catheterization laboratory in a typical clinical setting. METHODS AND RESULTS: We performed a single-center, retrospective analysis of 400 consecutive patients who underwent diagnostic and interventional cardiac catheterizations in a predominantly TRA laboratory with traditional fluoroscopy (N=200) and a new image noise reduction fluoroscopy system (N=200)...

We investigated the impact of preoperative ultrasonography of the forearm circulation on radial artery conduit selection. Preoperative ultrasound of the forearm circulation was performed routinely in 536 patients planned for radial artery harvesting. The safety assessment of the harvest included the following algorithm of tests: the ultrasound, the Allen test, and pulse oximetry. The quality criteria that were used to exclude a radial artery from harvesting were small size of the artery, diffuse atherosclerosis, calcifications, and severe neointimal hyperplasia...

BACKGROUND: Coronary artery bypass grafting (CABG) with a composite Y-graft made of the left internal thoracic artery (LITA) and another arterial graft has a risk for hypoperfusion. Changes over time in the diameter of the LITA anastomosed to the left anterior descending coronary artery (LAD) are not known. METHODS: Data were collected for 71 patients who had undergone coronary angiography (CAG) immediately and at 1 year following off-pump CABG with a composite Y-graft made of the LITA and either the radial artery or the right gastroepiploic artery...

BACKGROUND: Graft reperfusion poses a critical challenge during liver transplantation and can be associated with hemodynamic instability/postreperfusion syndrome. This is sequel to ischemia-reperfusion injury and normothermic machine preservation (NMP) may affect hemodynamic changes. Herein, we characterize postreperfusion hemodynamics in liver grafts after NMP and traditional cold preservation. MATERIALS AND METHODS: Intraoperative records of patients receiving grafts after NMP (n = 6; NMP group) and cold storage (CS) (n = 12; CS group) were compared...

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...
