An 81-year-old man was hospitalized because of fever and pain in the temporal region. Temporal artery biopsy revealed temporal arteritis; steroid therapy was started. Chest computed tomography and kidney biopsy revealed interstitial pneumonia and necrotizing crescentic glomerulonephritis, respectively. Because his myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) level was 215.0 U/mL, a diagnosis ...

The use of thrombolytic therapy in the treatment of thrombosed infrainguinal native arteries and bypass grafts has increased over the years. Main limitation of this treatment modality, however, is the occurrence of bleeding complications. Low intensity ultrasound (US) has been shown to accelerate enzymatic thrombolysis, thereby reducing therapy time. So ...

Acute revascularization is associated with improved outcomes in ischemic stroke patients. It is unclear which method of intra-arterial intervention, if any, is ideal. Promising approaches in acute stroke treatment are likely a combination of intravenous and endovascular revascularization efforts, combining early treatment initiation with direct clot manipulation and/or PTA/stenting. In ...

Isolated iliac artery aneurysms are uncommon, comprising less than 2% of all abdominal aneurysmal disease. Although they have a fairly innocuous natural history, when they have attained a large size they carry a significant risk of rupture. Rupture is associated with significant morbidity and mortality. Therefore, an early diagnosis and ...

Intracerebral haematoma (ICH) occurs in one-third of patients with aneurysmal subarachnoid haemorrhage (SAH) and is associated with poor prognosis. Identification of risk factors for ICH from aneurysmal rupture may help in balancing risks of treatment of unruptured aneurysms. We assessed potential clinical and aneurysmal risk factors for ICH from aneurysmal ...

This monograph reviews currently accepted criteria for extirpation of the aneurysmal thoracic aorta. Presence of symptoms suffices to justify resection regardless of size. For asymptomatic patients, resection of the ascending aorta at 5 to 5.5 cm is warranted. The descending aorta can be watched until slightly larger sizes (ie, 5.5-6 ...

Pulmonary arterial hypertension (PAH) is a serious, progressive condition, which can present idiopathically or secondary to conditions such as systemic sclerosis or congenital heart disease. The condition exists in both adult and paediatric forms, which possess several similar characteristics. Adult and paediatric PAH can, however, be distinguished based on underlying ...

Exercise electrocardiography test (EET) has limited sensitivity and specificity. Recently, color M-mode-derived propagation velocity of the descending thoracic aorta (APV) has been shown to be associated with coronary artery disease (CAD). We evaluated the incremental value of APV for better prediction of CAD in EET-positive patients. Color M-mode APV was ...

Aortic arch aneurysms present a significant clinical challenge. Historically, open repair has been the mainstay of therapy, but it is associated with significant morbidity and mortality. In particular, the risk of stroke is not insignificant. The development of endovascular therapies has allowed for the less invasive treatment of thoracic aortic ...

A 36-year-old woman suffered meningioma in her right cerebellopontine angle. Air embolisms often complicate sitting-position surgeries. Because TEE guides the localization of central venous catheters and promptly locates air embolisms promptly enough for effective treatment, TEE is an effective monitoring method for sitting-position surgeries.
