Platypnea-orthodeoxia syndrome in a patient with poor activity of daily living: Struggling with a definitive diagnosis.

Unlabelled: A 73-year-old female patient was diagnosed with lumbar spinal stenosis by an orthopedic surgeon. During admission for further evaluation, she was found to have hypoxemia. Contrast-enhanced computed tomography revealed a 43-mm ascending aortic aneurysm, but there were no signs of pulmonary embolism, and no abnormalities were detected in the lung fields.

Clinical Course of Asymptomatic Isolated Distal Deep Vein Thrombosis of the Leg: A Single-Institution Study.

: The natural history of asymptomatic isolated distal deep vein thrombosis (DVT) of the leg is unclear. This study aimed to describe a 3-month and 1-year clinical course after diagnosis of asymptomatic isolated distal DVT of the leg. : This study included 127 patients with asymptomatic, sonographically proven isolated distal DVT who did not receive anticoagulant therapy and were retrospectively evaluated at our hospital between May 2014 and September 2016.

Stanford type B aortic dissection is more frequently associated with coronary artery atherosclerosis than type A.

Background: The relationship between aortic dissection and coronary artery disease is not clear. The purpose of this study was to clarify the difference in the rate of coronary artery atherosclerosis between Stanford type A and type B aortic dissection by reviewing our institutional database.

Methods: One hundred and forty-five patients (78 males, 67 females; mean age: 60 ± 12 years) admitted to our hospital with acute aortic dissection who underwent coronary angiography during hospitalization from 2000 through 2002 were enrolled in this study.

[Effectiveness of the Waffle Procedure for Constrictive Pericarditis].

A 66-year-old woman was referred to our hospital with dyspnea. Right-sided congestive pleural effusion of an unknown etiology was detected and she was diagnosed with constrictive pericarditis. Pericardiectomy was performed via median sternotomy under extracorporeal circulation because severe adhesion was observed.

[Surgical Repair of Coronary-pulmonary Artery Fistulae with Giant Coronary Aneurysm].

A 69-year-old woman was referred to our hospital due to dyspnea on exertion and a heart murmur. A chest X-ray showed a bulge at the left 3rd arch and chest computed tomography( CT) revealed a giant mass adjacent to the right ventricular outflow. Multidetector-row CT and coronary angiography showed a giant coronary aneurysm (55×45 mm) and fistulae arising from the left main coronary trunk and entering into the main pulmonary artery (PA).

Frequency and implication of ST-T abnormalities on hospital admission electrocardiograms in patients with type A acute aortic dissection.

Although patients with Stanford type A acute aortic dissection often show ST-T abnormalities at presentation, the frequency and implication of such findings remain unclear. To clarify these points, admission electrocardiograms from 233 patients admitted ≤6 hours after symptom onset who underwent emergency surgery for type A acute aortic dissection were studied. The prevalence of electrocardiographic (ECG) patterns was 51% for ST-T abnormalities (4% for ST-segment elevation and 47% for ST-segment depression and/or negative T waves), 30% for normal ECG findings or no significant ST-T changes, and 19% for ECG confounders such as bundle branch block or left ventricular hypertrophy.

Endovascular repair of a presumed aortoduodenal fistula.

This report describes the use of transluminal endovascular grafting for the treatment of a presumed aortoduodenal fistula. The patient was a 71-year-old man who had undergone resection and graft replacement for an abdominal aortic aneurysm. Three years after operation, melena was caused by perforation of the duodenal wall by a pseudoaneurysm at the proximal graft anastomosis.
