Blalock-Taussig 手術における吸収性縫合糸の有用性に関する臨床的研究

抄録

Absorbable sutures were used for anastomosing the subclavian artery to the pulmonary artery in 20 cases undergoing Blalock-Taussig operation and the results were compared with those obtained with nonabsorbable suture in 22 cases. 1) With absorbable sutures, gratifying operative results were obtained with as high a shunt patency rate as 100%, even though an additional shunt operation was required not infrequently. 2) There was no operative mortality, nor did occur rupture or aneurysm at the anastomotic site due to its diminished anti-tensile strength. 3) Cardio-angiographic evidence indicates that the use of absorbable sutures well prevented, the occurrence of stenosis at the anastomotic site, where inner vessel surfaces remained virtually smooth and, in some instances, the vessel itself was even growing. 4) Macroscopically, the anastomotic site was smooth-appearing and there were no visible sutures; histologically tissue reactions at the anastomotic site were modest. 5) From the facts that their use was associated with virtually nonoccurrence of stenosis of the anastomosed vessel and a good patency rate of the shunt, absorbable sutures were concluded to provide a useful suture material for use in Blalock-Taussig operation.
