Transcatheter Arterial Embolization of Arterial Esophageal Bleeding with the Use of N-Butyl Cyanoacrylate

چکیده
OBJECTIVE To evaluate the clinical efficacy and safety of a transcatheter arterial embolization (TAE) with N-butyl cyanoacrylate (NBCA) for the treatment of arterial esophageal bleeding. MATERIALS AND METHODS Between August 2000 and April 2008, five patients diagnosed with arterial esophageal bleeding by conventional angiography, CT-angiography or endoscopy, underwent a TAE with NBCA. We mixed NBCA with iodized oil at ratios of 1:1 to 1:4 to supply radiopacity and achieve a proper polymerization time. After embolization, we evaluated the angiographic and clinical success, recurrent bleeding, and procedure-related complications. RESULTS The bleeding esophageal artery directly originated from the aorta in four patients and from the left inferior phrenic artery in one patient. Although four patients had an underlying coagulopathy at the time of the TAE, angiographic and clinical success was achieved in all five patients. In addition, no procedure-related complications such as esophageal infarction were observed during this study. CONCLUSION NBCA can be an effective and feasible embolic agent in patients with active arterial esophageal bleeding, even with pre-existing coagulopathy.

We read with great interest the article by Park et al. (1), recently published in the Korean Journal of Radiology, whom reported on the effectiveness of selective emboliza-tion using N-butyl cyanoacrylate (NBCA) in patients with acute arterial esophageal bleeding. We have several comments: over the last decade, transcatheter arterial embolization (TAE) has gained widespread acceptance as a firs...

We present two cases of acquired uterine arterial venous malformation (AVM) which was diagnosed because of massive genital bleeding successfully treated with transcatheter arterial embolization (TAE), using N-butyl-2-cyanoacrylate (NBCA) under balloon occlusion. Balloon occlusion at the uterine artery was performed in both patients for diffuse distribution of NBCA in multiple feeding branches, ...
