Compression stenosis of the celiac trunk or Dunbar syndrome, a clinical and anatomical syndrome characterized by chronic abdominal pain, is congenital pathology based on compression median arcuate ligament diaphragm. The narrowing lumen entails hemodynamic disturbances in artery itself branches extending from it, which leads to shortage blood supply organs digestive system. Inadequate arterial ...

BACKGROUND AND PURPOSE Many reports have confirmed that endoscopic ultrasonography (EUS) can differentiate gastric submucosal tumor from extragastric compression, but only a few specifically concentrated on EUS in identifying the causes of external compression. MATERIALS AND METHODS From May 1993 to May 2001, we used EUS in 238 patients to diagnose gastric submucosal tumor or external compres...

May–Thurner syndrome (or iliocaval compression syndrome) is defined as a compression of the iliac vein that results in decreased flow in the vein and the left lower extremity due to a vascular malformation. It may result in left leg edema, pain, iliofemoral DVT, and postthrombotic syndrome. Compression of the left common iliac vein by the right common iliac artery against the underlying fifth l...

This article introduces 2 new cardiopulmonary resuscitation (CPR) concepts: (1) the use of only rhythmic abdominal compression (OAC) to produce blood flow during CPR with ventricular fibrillation and (2) a new way of describing coronary perfusion effectiveness, namely, the area between the aortic and right atrial pressure curves, summed over 1 minute, the units being millimeters of mercury per ...
