RESUMO

This article analyzes mainly the X-ray imaging acquisition parameters in AXIOM Artis X-ray equipment, the relationship between the parameters, and how to select acquisition parameters in cardioangiography. We have sought a set of X-ray imaging acquisition parameters for producing optimal image in cardioangiography.

RESUMO

<p><b>BACKGROUND</b>To investigate the indication, complication and efficacy of bronchial artery embolization for the management of lung cancer with massive hemoptysis.</p><p><b>METHODS</b>Thirty-eight cases of lung cancer with massive hemoptysis were retrospectively analyzed in our hospital from January 1996 to January 2003. All cases presented with acute hemoptysis from 220 to 980 ml daily, with a mean of 290 ml daily. A digital subtracted bronchial arteriogram was perfomed and bleeding arteries were embolized.</p><p><b>RESULTS</b>Hemoptysis decreased gradually in all cases and ceased in 3 or 4 days after embolization. Recurrence was found only in one case 2 months after embolization and second embolization was applied to control hemoptysis. No serious complications occured.</p><p><b>CONCLUSIONS</b>Bronchial artery embolization is safe and efficient for the management of lung cancer with massive hemoptysis.</p>

RESUMO

Objective To study the methods and value of emergency interventional therapy in digestive tract bleeding.Methods 61 cases with digestive tract bleeding accepted emergency angiography.According to find out positions and causes of bleeding during angiography,these patients accepted arterial embolization and /or perfusion of vasoconstrictor substance.Results In 29 cases accepted arterial embolization and 32 cases accepted perfusion of vasoconstrictor substance,the stoped bleeding immediately occured in 100% and 82.7% respectively.Bleeding recurrence was 3 cases in the patients with arterial embolization one week later and 25 cases of the patients with perfusion of vasoconstrictor substance forty-eight hours later.Conclusion To treat the digestive tract bleeding by arterial embolization or vasoconstrictor substance perfusion are safe and effective hemostatic ways during emergency angiography.Though the bleeding recurrent rate is high after vasoconstrictor substance perfusion,these ways can race against time for surgical operation.

RESUMO

Objective To investigate the clinical efficacy,indications and complications of transcatheter arterial embolization for the treatment of traumatic hemorrhage of liver.Methods Retrospectively analyzed 33 cases of traumatic hemorrhage of liver admitted to West China Hospital from May 1996 to May 2006.Twenty-four cases underwent hepatic arterial angiography and were diagnosed as hepatic arterial pseudoaneurysms and followed by superselective embolization of the feeding vessel with gelatin sponge and/or spring coils.Results Embolization was succeeded technically in 28 pseudoaneurysms of 24 cases.Rebleeding occurred in 2 cases and a second embolization was performed with one recovered uneventfully.The other died of rebleeding and severe abdominal infection one week after the second embolization.Fever unrelated to embolization occurred in 9 cases.Conclusion Transcatheter arterial embolization is safe,prompt and effective for the treatment of hemorrhage due to hepatic injury.(J Intervent Radiol,2007,16:226-228)
