Contrast media injection into right coronary artery caused thrombus extraction to aorta that may have resulted in left main trunk thrombosis.

A 59-year-old man with inferior acute myocardial infarction underwent an urgent coronary angiography and as a result a total occlusion of the ostial right coronary artery (RCA) was observed. Interestingly, the thrombus in the RCA clearly shortened within 2.3 s during the contrast media injection.

Hyperuricemia as a risk factor for progressive renal insufficiency after coronary intervention in patients with chronic kidney disease.

The development of renal insufficiency after percutaneous coronary intervention (PCI) is associated with increases in morbidity and mortality. Recent studies have reported that hyperuricemia (HU) results in hypertension, intrarenal vascular disease, and renal injury. We postulated that HU contributes to progressive renal disease after PCI.

Risk factors for death in 224 cases of hepatocellular carcinoma after transcatheter arterial chemoembolization.

Background/aims: Transcatheter arterial chemoembolization (TACE) has been reported as effective therapy for unresectable hepatocellular carcinoma (HCC), however, few have described methods for predicting prognosis, especially in patients treated by repeated TACE. To determine risk factors for death and try to predict the prognosis, we evaluated clinical data.

Methodology: We retrospectively analyzed the clinical parameters of 224 patients with unresectable HCC treated with repeated TACE from January 1997 to December 2007.
