To know the characteristics of mortality from aortic aneurysms in Japan, the age-adjusted and age-specific mortality rates of the diseases were calculated based on the Vital Statistics of Japan published from the Statistics and Information Department, Minister's Secretariat, Ministry of Health and Welfare. The overall age-adjusted mortality rate increased 24.8-fold from 0.43 to 10.98 per 100,00...

BACKGROUND Recently, thoracic aortic stent grafting has emerged as an alternative therapeutic modality for patients with thoracic aortic aneurysms and aortic dissections. However, its application has been limited to descending thoracic aortic aneurysms distal to the aortic arch. We report our initial clinical experience of endovascular branched stent graft repair for aortic arch aneurysms. ME...

STUDY OBJECTIVE Lipoprotein(a) (Lp[a]) level is a risk factor for ischemic heart disease, cerebrovascular disease, and peripheral vascular disease. However, few data are available concerning the relationship between Lp(a) level and severity of thoracic aortic atherosclerosis. We hypothesized in this transesophageal echocardiography (TEE) study that Lp(a) level is a marker of severity of thoraci...

BACKGROUND Progressive medial degeneration and atrophy is thought to be a cause of ascending thoracic aortic aneurysms in the elderly. Extensive apoptosis of vascular smooth muscle cells (VSMCs) has been demonstrated in the media of abdominal aortic aneurysms. We investigated whether medial atrophy from loss of VSMCs occurs in primary ascending thoracic aortic aneurysms. METHODS AND RESULTS M...

The association between coronary artery disease (CAD) and thoracic aortic plaques has often been reported using transesophageal echocardiography. However, studies showing the association between CAD and abdominal aortic plaques are scarce. CMR can visualize plaques in both the thoracic and abdominal aortas. Using CMR, we investigated the associations of thoracic and abdominal aortic plaques wit...

Endovascular management concepts have recently emerged as valuable treatment options for both simple and complex disorders involving both the distal arch and descending thoracic aorta. With growing use of endovascular stent-grafts the technique has generated broad interest. Nevertheless, an ideal device for different thoracic aortic conditions is not available yet. After initially using the fir...

We present the findings in a 57-year-old man with a rupture of the thoracic aorta that originated in a penetrating atherosclerotic aortic ulcer. It formed a large hematoma that clinically mimicked a true saccular thoracic aneurysm. The possibility of penetrating aortic ulcer should be considered in the differential diagnosis of aortic aneurysm.

Pseudoaneurysm after thoracic endovascular aortic repair (TEVAR) is very rare. We report a case of thoracic aortic pseudoaneurysms due to flares at the proximal end of a stent graft after TEVAR for ductal aneurysm. We describe a total aortic arch replacement in this case using a modified cuffed anastomosis technique with an elephant trunk procedure leaving the partial stent graft in situ.

OBJECTIVE Mean platelet volume (MPV) plays a pivotal role in the pathophysiology of atherosclerotic disease. Thoracic aortic intima-media thickness (IMT) was reported as an earlier marker of preclinical atherosclerosis than carotid IMT. However, the relationship between MPV and aortic IMT was not investigated. We aimed to assess the relationship between thoracic aortic IMT and MPV in patients u...

OBJECTIVE Although recent progress has expanded the indications for thoracic aortic surgery to include elderly patients, the procedure remains extremely invasive. We performed a chart review to determine the early and late outcomes of thoracic aortic surgery using hypothermic circulatory arrest (HCA) and antegrade selective cerebral perfusion (ASCP) in octogenarians.
