Kedar S Lavingia, Anahita Dua, Jordan R Stern
The advancement of endovascular therapy has led to minimally invasive solutions to increasingly complex aortic pathology, including thoracoabdominal aneurysms and those involving the visceral segment. Upper extremity access is beneficial in a variety of these complex interventions, and may be absolutely required for certain procedures such as placement of parallel chimney grafts. Traditionally, the brachial artery has been the primary access site on the arm, using either a percutaneous or open approach. Brachial access is safe and effective, and remains suitable for the majority of clinical situations...

Use of coronary artery bypass grafting (CABG) has had a resurgence, as clinical trial data emerged showing that it remains the standard of care for patients with complex lesions. Debate exists regarding various factors, including endoscopic vs open vein-graft harvesting, single vs bilateral mammary artery grafts, radial artery vs saphenous vein grafts, right internal mammary artery vs radial artery grafts, and on-pump vs off-pump surgery. More recent developments include minimally invasive approaches, robotics, and hybrid revascularization, which are changing the risk-benefit ratio for this patient population...

Background -Whether a second arterial conduit improves outcomes after multi-vessel coronary artery bypass grafting remains unclear. Consequently, arterial conduits other than the left internal thoracic artery are seldom used in the United States. Methods -Using a state-maintained clinical registry including all 126 non-federal hospitals in California, we compared all-cause mortality and rates of stroke, myocardial infarction, repeat revascularization, and sternal wound infection between propensity score-matched cohorts who underwent primary, isolated multi-vessel coronary artery bypass grafting with the left internal thoracic artery, and who received a second arterial conduit (right internal thoracic artery or radial artery, N=5,866) or a venous conduit (N=53,566) between 2006 and 2011...

BACKGROUND: Transradial access (TRA) is preferred for coronary angiography (CA) or percutaneous coronary intervention due to reduced access-related complications, and mortality especially for patients with ST elevation myocardial infarction. Radial artery occlusion (RAO) is a known complication of TRA, and precludes its use as a future access site, conduit for coronary artery bypass grafting or for hemodialysis fistula placement. Although a standard dose (SD) heparin of 5000 Units is used during TRA, the risks of RAO and hematoma compared to lower dose (LD) remain unclear...

BACKGROUND: Arteriovenous graft (AVG) infections can present as major life-threatening hemorrhage or sepsis in a chronic kidney disease patient. Frequently, all these patients present in critical condition which need prompt and expeditious management. Various procedures are described for management of infected grafts and its bleeding complications. However, these procedures are associated with postop-operative bleeding and persistent infection. The aim was to study brachial artery ligation (BAL) near the elbow joint in the management of an infected AVG...

A false aneurysm or pseudoaneurysm (PA) is the formation of a pulsatile and encapsulated hematoma in communication with the lumen of a perforated artery. Its origin is different but most cases are associated with a traumatic event. Currently, the referenced treatment is endovascular surgery but it is not feasible for the majority of vascular surgeons working in a tropical environment. The aim of this study was to describe the diagnostic and therapeutic aspects of arterial PA (APA) encountered in our institution and to evaluate the place of open surgical technique in their management...

Recent evidence shows that multi-arterial coronary artery bypass grafting (MABG) based on bilateral internal thoracic (BITA) or left internal thoracic (LITA) and radial artery (RA) improves long-term outcomes compared with single arterial coronary artery bypass grafting (SABG) (LITA + saphenous vein graft). How this evidence affected the worldwide use of MABG, if at all, is not well defined. Accordingly, we report 10-year temporal trends of MABG utilization from 2 continents. A study population of 1,683,434 non-emergent, primary, isolated LITA-based coronary artery bypass grafting (CABG) (≥2 grafts) patients was derived from the Society of Thoracic Surgeons (STS) (1,307,528 (79...

A tailored therapy to patient requirements by combining endovascular and surgical steps can be necessary to prolong the life of a vascular access. Stent grafts play a growing role for the therapy of dialytic access complications. Randomized multi-center trials, however, support the on-label use of stent grafts in the treatment of graft venous outflow and in-stent restenosis. The main contraindication to their use is an ongoing infection. We report two cases of new off-label application of Viabahn (Gore, flagstaff, USA) stent graft...

Performing resection of a biliary tract malignancy with a hepatic artery aneurysm is very challenging. Resection of the extrahepatic bile duct and extra-anatomical reconstruction can be successfully performed using free radial artery autografts from the aorta to the right hepatic artery. Hepatic artery thrombosis can be prevented with intimal preservation.

Radial artery graft spasm in the perioperative or postoperative period of coronary bypass surgery necessitates urgent treatment due to risk of graft failure and mortality. Herein, we evaluated the effect of iloprost, a prostacyclin (PGI2) analogue, against the contractions produced by noradrenaline and potassium chloride on isolated human radial artery. Following the determination of endothelial and vascular relaxing capacities of the arteries, iloprost (10(-9)M-10(-6)M) was cumulatively applied on rings precontracted submaximally with the spasmogens...

Celiac trunk aneurysms are uncommon vascular lesions; treatment is usually an open surgical operation; in the medical literature, only few cases of celiac aneurysm treated with endovascular technique are reported; coil positioning or stent-graft placement are described using a femoral vascular access as first choice.Here we describe the case of a 57-year-old man with an asymptomatic large celiac trunk aneurysm involving the origin of the splenic, left gastric and hepatic arteries. The patient was treated in an elective clinical setting with a totally endovascular procedure performed through the left radial artery...

BACKGROUND The use of decellularized biological scaffolds for the reconstruction of small-diameter vascular grafts remains a challenge in tissue engineering. Thrombogenicity is an important cause of obstruction in these vessels due to decellularization. Seeding of the decellularized vascular constructs with endothelial cells is therefore a prerequisite for the prevention of thrombosis. The aim of this study was to seed decellularized baboon arteries with endothelial cells and to compare the thrombogenicity to that of decellularized arteries after circulation of blood...
