作者研究了24例应用球囊扩张的各类胃肠道狭窄性病变,11例为上胃肠道狭窄,13例为直肠病变。24例中男8例,女16例,年龄26～87岁。所有病例在扩张前均作了造影检查。扩张使用Lun-derquist-Owman球囊导管,直径为15mm,最大径为22mm。球囊长度分别为6cm和8cm。未充胀的15mm球囊导管外径为14F,22mm球囊外径为19F。充胀的球囊具有最大径,如果充胀压超过此极限(15mm球囊导管为15PSI,22mm球囊导管为9PSI),球囊会爆裂。导管尖端长约4cm。有的病变太窄不能通过标准导管,先使用9mm的血管成形球囊
The authors studied various gastrointestinal stenoses in 24 patients with balloon dilatation, 11 with upper gastrointestinal stenosis and 13 with rectal lesions. 24 cases of male 8 cases, 16 females, aged 26 to 87 years. All cases were dilated before angiography. The Lun-derquist-Owman balloon catheter was expanded for use with a diameter of 15 mm and a maximum diameter of 22 mm. The balloon lengths are 6 cm and 8 cm, respectively. The non-inflated 15mm balloon catheter has an outer diameter of 14F and a 22mm balloon diameter of 19F. The inflated balloon has the largest diameter and if the inflation pressure exceeds this limit (15 psi for a 15 mm balloon catheter and 9 psi for a 22 mm balloon catheter), the balloon will burst. The catheter tip is about 4cm long. Some lesions too narrow can not pass the standard catheter, the first use of 9mm angioplasty balloon
