a 52-year-old post-menopausal female was admitted to the emergency room due to acute onset of abdominal pain in the right lower quadrant. there was no history of trauma of the abdomen. contrast-enhanced multi-detector computed tomography (mdct) of the abdomen and pelvis revealed a massive right retroperitoneal hematoma and contrast extravasation from a right ovarian artery aneurysm. digital sub...

Introduction: Arteriovenous malformations (AVMs) are uncommon vascular lesions that can arise in any part of the body. Case Report: In this case study, we presented a huge AVM of the upper lip in a 70-year-old man that he noticed since 5years ago with slow growth in this period. Computed tomography angiography revealed a large AVM with feeders from the right...

22 anesthetized dogs were given a barium sulfate suspension intravenously in a dose sufficient to double mean pulmonary artery pressure. 10 sec breath-holding carbon monoxide diffusing capacity (D(LCO10)) was measured before and after this standard embolization in each dog. No post-embolic decrease in D(LCO10) was observed. In the study of this apparent paradox, it was found that the potential ...

Massive hemoptysis is a life threatening respiratory emergency with high mortality and the bronchial artery (BA) is its most frequent source. Herein, we report a case of a 76-year-old man with recurrent hemoptysis due to an aberrant right BA arising from the right internal mammary artery (IMA), an extremely rare origin, that was clearly depicted on pretreatment computed tomography angiography (...

RATIONALE Dieulafoy lesions are aberrantly large submucosal arteries most frequently associated with gastrointestinal hemorrhage. They are rarely identified in the bronchial submucosa and can cause massive hemoptysis. PATIENT CONCERNS We present three episodes of massive hemoptysis in two patients, the first with comorbid Alagille syndrome including multiple cardiac and pulmonary vascular abn...

Hemoptysis constitutes a common and urgent medical problem. Swift and effective management is of crucial importance, especially in severe, life-threatening cases. Because of bronchial artery or a branch of pulmonary artery erosion due to cavitary infiltration, bronchiectasis, fungus ball, broncholithiasis, or destroyed lung, the bleeding can lead to highly compromised gas exchange or sometimes ...
