In patients with known intestinal Behçet syndrome, CT can be useful in determining the extent of the lesions and in identifying cases in which complications are likely to occur.
The authors report two cases of orbital cavernous hemangioma diagnosed by Tc-99m RBC SPECT. Tc-99m RBC SPECT showed a typical scintigraphic pattern commonly seen in hepatic hemangioma in which there is intense focally increased uptake on delayed SPECT images. Tc-99m RBC SPECT in orbital cavernous hemangioma may be as useful a diagnostic modality as in hepatic hemangioma.
Purpose: To evaluate the clinical effectiveness of fluoroscopically guided balloon dilation in thetreatment of esophageal achalasia.Materials and Methods : Under fluoroscopic guidance, 21 balloon dilation procedures were performed in 14 patients with achalasia . A balloon with a diameter of 20 mm was used for the initial attempt. If the patient tolerated this welL the procedure was repeated with a 10-20mm balloon, placed alongside at the same session. If, however, the patient complained of severe chest pain and/or a postprocedural esophagogram showed an improvement, the additional balloon was not used. For patients whose results were unsatisfactory, the dilation procedure was repeated at sessions three to seven days apart.Results: Succesf 비 dilation was achieved in 13 of 14 patients(92.9% }, who needed a total of 20 sessions of balloon dilation , ranging from one to three sessions per patient(mean , 1.54 sessions). Esophageal rupture occured in one of 14 patients(7.1 %); of the 13 patients who underwent a successf비 dilation procedure, 12(92.3%) were free of recurrent symptoms during the follow -up period of 1 -56(mean , 18.5) months. The remaning patient(7.7%) had a recurrenceseven months after dilation.Conclusion: Fluoroscopically guided balloon dilation seems to be safe and effective in thetreatment ofesophageal achalasia.
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.
