Thoracic endovascular repair is considered the first-line treatment in complicated acute type B dissection. Central venous catheters provide valuable vascular access during endovascular treatments. However, central venous catheters are not without complications. Herein, we report a case of central venous catheter insertion into the false lumen of a complicated acute type B aortic dissection by direct aortic puncture. The tip of the central venous catheter was in the false lumen. The central venous catheter was left in place initially and was removed after graft stent deployment...

Embolic events from infective endocarditis can cause acute coronary syndrome. Mortality rate is high and optimal management might be different from those chosen in setting of classic atherosclerotic coronary artery disease. We present a case of 56-year-old male who had received 5 weeks of antibiotics for aortic valve endocarditis and developed acute ST segment elevation myocardial infarction in hospital settings. Interestingly, patient had recent left heart catheterization that was normal. This was recognized as embolic event from sterile vegetation...

AIMS: Self-expanding (SE) valves are characterized with long stent frame design and the radial force of the device exists both in the inflow and outflow level. Therefore, we hypothesized that device success of SE-valves may be influenced by ascending aortic dimensions (AAD). The aim of this study was to determine the influence of AAD on acute device success rates following SE transcatheter aortic valve replacement (TAVR). METHODS & RESULTS: In 4 centers in the United States and Asia, 214 consecutive patients underwent SE-TAVR...

Endovascular redo aortic operations are a challenging undertaking. Techniques for treatment date almost as far back as the original open repair itself. Risk factors for failure following aortic repair include larger AAA necks, severe neck angulation, as well as clinical variables such as age, family history, obesity and chronic obstructive pulmonary disease. The armamentarium of endovascular treatments is vast and increasing. Aside from provisional embolization of endoleaks or deferment to open repair conversion, attention should be directed toward obtaining adequate proximal and distal sealing...

PURPOSE OF REVIEW: To provide an overview of current recommendations and techniques used to image coarctations of the aorta. RECENT FINDINGS: Imaging of coarctation of the aorta in adults is moving away from conventional techniques such as echocardiography and invasive angiography. Echocardiography may assist in making the diagnosis but is limited in its ability to quantify the severity of coarctations. Current guidelines recommend that every patient with a coarctation must undergo a computed tomography (CT) or MRI scan for accurate delineation of morphology...

Some studies consider the different physical properties of the stent graft when compared with the blood vessel on the basis of vascular lesions that may require further intervention. We present a case in which a patient developed an intramural hematoma at the distal landing of previous thoracic endovascular aortic repair (TEVAR) that required the relining with a flared prosthesis. During follow-up, we observed the appearance of more caudal hematoma. We decided to observe this lesion with close radiological controls...

Understanding of the hemodynamics of Type B aortic dissection may improve outcomes by informing upon patient selection, device design, and deployment strategies. This project characterized changes to aortic hemodynamics as the result of dissection. We hypothesized that dissection would lead to elevated flow reversal and disrupted pulsatile flow patterns in the aorta that can be detected and quantified by non-invasive magnetic resonance imaging. Flexible, anatomic models of both normal aorta and dissected aorta, with a mobile intimal flap containing entry and exit tears, were perfused with a physiologic pulsatile waveform...

Late collapsing of a stent graft is an extremely rare event, with one existing report describing this phenomenon. A 65-year-old man with a history of endovascular aortic repair for an abdominal aortic aneurysm presented with paraplegia and bilateral lower limb ischaemia. Contrast-enhanced computed tomography showed a dissection of the descending thoracic aorta and a collapsed stent graft, resulting in bilateral lower limb ischaemia. Subsequent axillo-bifemoral bypass resolved his lower extremity functions. The patient required haemodialysis due to acute kidney failure...

Delivery of stent grafts during thoracic endovascular aortic replacement can be challenging, especially in aortic arches with severe angulation. Several techniques have been recommended to achieve this. We introduce a simple technical method, transfemoral snare-assisted device advance, which was successful in a 72-year-old woman with an aneurysm in a severely angulated aortic arch and review various technical tips.
