Title: Ultrasonic aid in transvenous instrumental dilatation for patients with membranous stenosis of the hepatic portion of the inferior vena cava. Author: Yamazaki Y, Terashima M, Otani S, Yazawa M, Eguchi S, Tsukada K, Tsuchiya Y. Journal: Jpn J Surg; 1985 May; 15(3):209-14. PubMed ID: 3162056. Abstract: We report two cases of a membranous stenosis of the hepatic portion of the inferior vena cava. Membranotomy was performed with a specially designed instrument similar to a Tubbs' dilator following balloon membranotomy. During the procedures, ultrasonographic observations were made and this technique was confirmed to be effective for proper placing of a balloon and a dilator in the stenotic portion. Follow-up evaluation of the procedures was also feasible with this ultrasonic aid.[Abstract] [Full Text] [Related] [New Search]
