研究目的: |
本研究将采用体外高能聚焦超声治疗机进行肾下极脂肪改性(PRFM)来治疗轻-中度原发性高血压,通过对接受该项非侵入性肾下极脂肪改性治疗的受试者的随访,评估该疗法对降低原发性高血压的疗效及安全性。通过本研究我们将尝试建立一种全新的非侵入性高血压辅助治疗手段,为临床上治疗高血压提供一种新的辅助方法。 |

Objectives of Study: |
The aim of this study was to assess clinical safety and efficacy outcomes of peri-renal fat modification(PRFM) in regulating blood pressure of primary moderate combined hypertension patients via an externally delivered, completely noninvasive, mechanical/thermal coupling effects,high-intensity focused ultrasound system(HIFU) |
||||||||||||||||||||||
|
药物成份或治疗方案详述: |
治疗方案:患者呈侧卧位,我们使用凸阵超声探头(3.5-MHz)垂直于患者两侧腰部(肾区)以及治疗床,肾下极脂肪定义为肾尾纤维膜和肾尾筋膜之间的脂肪组织。通过超声纵切面及横切面标记肾下极脂肪囊最大切面及直径。并且根据患者呼吸运动标测出安全治疗区域,通过HIFU超声聚焦产生的热效应及机械效应,破坏灭活肾下极脂肪组织。为了保证安全,我们时时监控治疗过程,前两个病人起始的治疗功率设定为80瓦特,后5个病人治疗功率设定为120瓦特,代确立了治疗技术安全性后,后续患者均以150瓦特得初始功率进行治疗,患者并未使用任何止痛药及镇静剂,我们将根据患者承受能力调整治疗功率。 |

Description for medicine or protocol of treatment in detail: |
We used a convex array ultrasound probe(3.5-MHz) located on the lateral abdominal wall with a side-lying position of patient and kept the probe perpendicular to the treatment bed .The volume of caudal perirenal fat each side was defined as the adipose tissue between the caudal fibrous membrane of kidney and caudal renal fascia. Transverse and longitudinal section scanning was carried out to measure and mark the caudal renal adipose capsule from the maximum section.With focusing the resulting ultrasound beam to the target area,the PRFM therapy was performed and the target area would be corrected in real time for motions associated with breathing and other patient movements.To maximise patient safety, we started the study by staging the procedure.The initial treatment power of the HIFU was set at 80 watt for the first two patients and 120 watt for 5 patients therafter. After establishing safety of the technique, we proceeded with initial power of 150 watt for both sides with no narcotic and sedative drugs. The power would be adjusted if beyond patients tolerance during the procedure. |

随机方法(请说明由何人用什么方法产生随机序列): |
本课题为前瞻性,非随机对照性,预初性研究。筛选方法: 1.门诊初步筛选:宣传及募集高血压病人至门诊根据诊室血压及降压药物服用情况行维持6周的初步筛选并预分组。 2.入院二次筛选:术前7天入院行24h动态血压监测及安全性指标检查进一步行二次筛选。 3.完成二次筛选的患者最终入选,并根据诊室血压及动态血压进行分组。 |
