Clavicle fractures are common; however, complications are unusual. Two such complications, subclavian artery pseudoaneurysm and brachial plexopathy, are rare events that can cause significant morbidity and mortality. We report the case of a 53-year-old man who presented with shoulder swelling and right arm weakness for 1 week. Three weeks before, ...

The role of internal mammary artery grafts in facilitating retrograde chronic total occlusion interventions is controversial. We describe two cases demonstrating: (a) retrograde wiring via a left internal mammary artery graft; and (b) using the left internal mammary graft for vessel visualization while retrograde crossing to the right coronary artery ...

Right pulmonary artery to left atrium fistula is a rare anatomic variation of pulmonary arteriovenous malformation in which the initial connection exists between a pulmonary artery and a pulmonary vein, but during vascular development the pulmonary vein gets incorporated into the left atrium. Though nearly 60 such cases have been ...

Although 15 to 20 percent of patients with subarachnoid haemorrhage (SAH) do not have a vascular lesion on four-vessel cerebral angiography, venous injury is a potential cause. This case describes an intracranial catheter associated with nonaneurysmal SAH. It suggests that intrathecal catheters can cause vascular injury, and that nonaneurysmal perimesencephalic ...

Diagnostic and interventional coronary procedures via cannulation of the radial artery have proven to be useful in patients with acute coronary syndrome (ACS) ST-segment elevation myocardial infarction, non-ST-segment elevation ACS, and non-ACS clinical syndromes. In many patients, vascular access and catheter advancement can be difficult due to vessel size, vasospasm, ...

Endovascular treatment of pseudoaneurysms that develop as a complication of pancreatitis is increasingly more common. A case of a pseudoaneurysm of the abdominal aorta initially treated by implantation of a straight aortic stent-graft is presented. In the 4 months after the procedure, chronic inflammation of the retroperitoneal space caused a ...

Extracranial carotid artery aneurysm (ECAA) is an uncommon but serious condition. The morbidity and mortality of ECAA are assumed to be high when untreated. ECAA treatment presents a challenge because of accessibility of the carotid artery and lack of evidence-based guidelines. When exclusion of the aneurysm is considered, surgical resection ...

Acute stent thrombosis is a rare, life-threatening, and challenging complication of left main stenting. Equally challenging is treating a chronic saphenous vein graft occlusion. Though considered class III indication per ACC/AHA guidelines, the saphenous vein graft may be the only potential conduit for revascularization. Coronary perforation during chronic total occlusion ...

Agenesis of the internal carotid artery is a rare, usually asymptomatic congenital anomaly. Patients may remain asymptomatic because a network of collaterals develops in response to agenesis of the internal carotid artery, which is usually diagnosed as an incidental finding after magnetic resonance imaging. The collateral circulation is prone to ...

The established superiority of the internal thoracic artery as a coronary arterial conduit has led to its mandatory use in coronary artery bypass grafting surgery. Therefore, the damage of the internal thoracic artery during harvesting is an abysmal complication, after which the conduit is usually discarded. An alternative approach is ...

Reconstructive valve surgery in acute aortic dissection type A (AADTA) remains challenging. We describe a case of successful combined repair of the aortic and mitral valves, and replacement of the ascending aorta after AADTA with aortic and mitral insufficiency. Mitral valve repair was achieved by quadrangular resection of the posterior ...

The right ventricle (RV) is in charge of pumping blood to the lungs for oxygenation. Pulmonary arterial hypertension (PAH) is characterized by high pulmonary vascular resistance and vascular remodeling, which results in a striking increase in RV afterload and subsequent failure. There is still unexploited potential for therapies that directly ...

Anatomical variations of the digestive system arteries are important due to their clinical significance. However, anomalies in the inferior mesenteric artery (IMA) are the least common compared with the celiac trunk and superior mesenteric artery. This report describes the case of a 67-year-old man with an extremely rare variant in ...

The transradial approach (TRA) in coronary angiography is used less frequently than the transfemoral approach; the learning curve and transradial failure (TRF) have slowed its widespread use. We evaluate the incidence, causes, and predictors of TRF in TRA coronary angiographies in an unselected population. All elective coronary angiographies using TRA ...

Transesophageal echocardiography (TEE) has become an important monitoring tool for the anesthesiologist during repair of intracardiac defects. Although the incidence of reported complications associated with its use is low, one should be careful during the insertion and use of TEE probe, as it may result in potential devastating problems. We ...

Existing mouse artery ex vivo perfusion models have utilized arteries such as carotid, uterine, and mesenteric arteries, but not the aorta. However, the aorta is the principal vessel analyzed for atherosclerosis studies in vivo. We have devised a mouse aorta ex vivo perfusion model that can bridge this gap. Aortas ...

Transcatheter aortic valve implantation (TAVI) is associated with a risk of coronary obstruction. This complication is potentially lethal when the origin of the coronary arteries is anomalous. We describe two cases of TAVI with the SAPIEN XT (Edwards Lifesciences) and CoreValve devices (Medtronic) in patients with a single coronary artery. ...

In this study, we noted the common risk factors with atherosclerosis and chronic renal disease. We, therefore, hypothesized that the placement of a dialysis catheter would be a useful marker in identifying populations at increased risk of vascular disease (carotid, renal, and aortic). To further explore this issue, we examined ...
