Magnetic Resonance Angiography for Monitoring Prophylactic Endoscopic Treatment of High Risk Esophageal Varices

Abstract

MRA is useful for evaluating portal hemodynamics. With the aim of avoiding recurrence of esophageal varices, EIS was suitable for patients who had a hepatofugal supply vein for the varices because recurrence could be prevented by embolization of the supply vein. EVL may be expected to be efficacious in patients where no image of a hepatofugal supply vein is found on MRA.

Sclerotherapy for gastric fundal variceal bleeding: Is complete obliteration possible without cyanoacrylate?

“…The basic concept of the sclerotherapy method used in the present study and the main differences were as follows: (i) intravariceal injection of EOI under fluoroscopic guidance embolized not only the varices but also the feeders; (ii) EOI was retained in the varices and feeders by infusion of vasopressin during sclerotherapy; and (iii) secondary bleeding from the puncture site was prevented by using thrombin glue and our special needle removal technique. These concepts were based on our previous study of sclerotherapy for esophageal varices using magnetic reasonance angiography, which showed that retention of EOI in the feeding vein of the varices led to a better outcome 31 . In the present study, successful retention of EOI was seen in 16/30 patients (53.4%), and initial hemostasis was achieved in 28 patients (93.3%).…”

Esophageal Varices: Evaluation with Transesophageal MR Imaging—Initial Experience

“…Few morphologic studies have been performed to assess the presence and dimensions of esophageal varices (32)(33)(34).…”

MR angiography of esophageal mural veins in portal hypertension: a correlation with endoscopic grades of esophageal varices

“…From a diagnostic standpoint, the utility of these methods depends on their potential to visualize portal venous anatomy with all its tributaries in any imaging plane. These imaging techniques also permit visualization of the varicose veins in the esophageal wall without discomfort to the patient and without additional cost and complication risk (7).…”

“…In addition to these methods, upper gastrointestinal barium studies, endoscopic Doppler ultrasonography, magnetic resonance imaging (MRI), MR angiography, computed tomography (CT), and transesophageal MRI are the techniques that can be used in the diagnosis of esophageal varices (2)(3)(4)(5)(6)(7)(8).…”
