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...

The primary hypothesis of the ROMA trial is that in patients undergoing primary isolated non-emergent coronary artery bypass grafting, the use of 2 or more arterial grafts compared with a single arterial graft (SAG) is associated with a reduction in the composite outcome of death from any cause, any stroke, post-discharge myocardial infarction and/or repeat revascularization. The secondary hypothesis is that in these patients, the use of 2 or more arterial grafts compared with a SAG is associated with improved survival...

Congenital atresia of the left main coronary ostium is a rare coronary anomaly presenting in adulthood. A 48-year-old man presented with unstable angina. Coronary angiography showed an absent left coronary ostium with a super-dominant right coronary artery retrogradely filling the left system. Computed tomography-angiography with 3-dimensional reconstruction confirmed the absence of the left main coronary artery. In view of ongoing chest pain, the patient was offered coronary artery bypass surgery. Total arterial revascularization was performed with a left internal mammary artery-left radial artery Y-graft...

Transradial access is becoming the default strategy for routine coronary procedures, but there is still room for improvement. For instance, left radial access is known to offer some advantages for graft cases, less tortuosity, amongst other potential benefits. The downside has been the applicability of this access point on patients with a larger body mass index both from the viewpoint of the patient and the operator. The patient must lay with their arm in a supine position and the operator as a result must stand in a flexed position for an unknown period of time...

Bypass surgery is often used in the treatment of large and giant aneurysms. Major complications that often arise during the perioperative period include cranial nerve palsy, ischemic complications, and hyperperfusion. However, there have been a few reports about late onset complications such as anastomotic aneurysms. In particular, anastomotic aneurysm after high flow bypasses has never been reported. A 57-year-old woman who had been suffering from left eye pain was diagnosed with a large aneurysm of the left internal carotid artery (ICA) in the cavernous portion...

Although improved long-term outcomes obtained with the use of arterial grafts for coronary revascularization in comparison with the traditional association of a single arterial and saphenous vein grafts have been demonstrated in the overall population, the efficacy of this newer technique in the elderly is difficult to prove because their shorter life expectancy due to advanced heart disease, associated with severe comorbidities. Moreover, more widespread use of this technique is limited by the concerns on the potential morbidity, particularly the longer time required to perform the operation and the possibility of deep sternal wound infection in case of bilateral internal thoracic artery harvesting due to the decreased blood supply to the sternum and surrounding tissues...
