Percutaneous transluminal renal angioplasty (PTRA) is a well-established method to treat renal artery stenosis (RAS) in children and adults. However, a significant number of stenoses might not be treated by interventional techniques due to the inability to dilate the RAS. Conventional balloon angioplasty with a high-pressure coronary angioplasty balloon at 20 atm was unable to dilate a significant RAS in a 12-year-old child with severe renovascular hypertension (RR 195/125 mm Hg). After using a 4 mm cutting balloon, we achieved wide patency of the renal artery and an instant normalization of blood pressure without further need of antihypertensive therapy. PTRA using the cutting balloon technique may offer an additional therapeutic option for selected patients in whom conventional balloon angioplasty was not able to dilate RAS.
经皮腔内肾血管成形术(PTRA)是治疗儿童和成人肾动脉狭窄(RAS)的一种成熟方法。然而,由于无法扩张肾动脉狭窄,相当一部分狭窄可能无法通过介入技术治疗。使用20个大气压的高压冠状动脉成形术球囊进行传统球囊血管成形术,无法扩张一名患有严重肾血管性高血压(RR 195/125 mmHg)的12岁儿童的显著肾动脉狭窄。使用4毫米切割球囊后,我们实现了肾动脉的广泛通畅,血压立即恢复正常,无需进一步的抗高血压治疗。对于传统球囊血管成形术无法扩张肾动脉狭窄的特定患者,使用切割球囊技术的PTRA可能提供一种额外的治疗选择。
