In this small study, no differences were detected in the efficacy or the safety of EBL vs. EHP in the management of bleeding gastric Dieulafoy's lesions.
SMAC using left paramedian compression technique failed to improve CPP during CPR and resuscitation outcomes. Furthermore, this method could not avoid liver laceration.
ObjectiveThe study was performed to evaluate whether thallium reinjection RI distinguishes viable from nonviable myocardium among myocardial segments which showed persistent perfusion defect PD in patients with acute myocardial infarction AMI . Materials and Methods We studied 22 patients underwent PTCA after AMI. SPECT was performed in all patients using dipyridamole stress-4 hour redistribution RD followed by 24 hour RI protocols. Dysfunctional segs were classified into 5 groups 1 normal, 2 reversible, 3 mild to moderate PD, 4 severe PD and 5 reverse redistribution RR . All patients underwent follow up echocardiography after 4 months to assess regional wall motion WM improvement such as a criteria of viable myocardium. Results A total of 127 segs with abnormal WM was analyzed. Of 74 segs with PD, 17 23% showed enhanced uptake after 24 hour RI. Five of 17 segs 29% with PD that responded to RI with enhanced thallium uptake showed WM improvement. WM improvement were seen in the 24 of 57 segs 42% not responding to RI. All four segs 100% with RR that responded to RI showed improvement. WM improvement were not seen in the 5 of 8 segs 71% with RR not responding to thallium RI. Eleven 73% of 15 segs with mild-moderate PD after RI showed improvement, but 33% of segs with severe PD after RI did not showed improvement. Segs with mild-moderate PD after RI and fill in after RI showed improvement in comparison to segs with severe PD after RI p 0.05 . Conclusions These data indicate that because only small proportion of PD showed further perfusion improvement after RI and predictive value by the uptake after RI was low, there was limited role of RI after myocardial infarction. Usefulness of RI could be found in segs showing RR responding to RI in AMI reflects viable myocardium.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
