Abstract

Background: A recent meta-analysis of randomized control trials demonstrated a significantly higher risk of major amputation in patients treated with drug-coated balloons (DCBs) compared with standard treatment, especially in high-dose paclitaxel-coated DCBs. Distal particulate embolization after DCB use was considered a potential cause of the higher incidence of major amputation. The current study aimed to histologically and biologically compare biologic drug effect and distal particulate embolization in 3 DCBs (a high-dose paclitaxel-coated DCB [IN.PACT Admiral] and 2 low-dose paclitaxel-coated DCBs [Ranger and Lutonix]).

Methods and results: The DCBs were inflated in the healthy descending aortas of 18 rabbits, followed by euthanasia 28 days after the procedure. The treated descending aorta and distal skeletal muscles were histopathologically evaluated, and paclitaxel concentrations were measured. The paclitaxel concentration of the treated lesion was highest for Ranger, followed by IN.PACT and Lutonix (Ranger vs IN.PACT vs Lutonix: 1089 [745-2170] pmol/mg vs 638 [160-2075] pmol/mg vs 25 [10-304] pmol/mg, respectively; p<0.0001). In the histopathological evaluation, the angle of severe medial smooth muscle cell loss was largest for Ranger followed by IN.PACT and Lutonix (12.8 [8.0-20.4] degree vs 1.4 [1.2-5.2] degree vs 0.8 [0.5-2.5] degree, respectively), with significant differences for Ranger vs IN.PACT (p=0.007) and Ranger vs Lutonix (p=0.002). However, paclitaxel concentrations of distal skeletal muscles were lowest for Lutonix, followed by Ranger and IN.PACT (12 [1-58] pmol/mg vs 15 [13-21] pmol/mg vs 42 [19-108] pmol/mg, respectively, p<0.0001). The numbers of arteries with downstream DCB effects were highest for IN.PACT, followed by Ranger and Lutonix (Ranger vs IN.PACT vs Lutonix, 3 [3-4] vs 4 [3-7] vs 2 [1-2], respectively), which was consistent with the measured tissue paclitaxel concentrations.

Conclusion: These findings suggest that Ranger demonstrates the strongest paclitaxel effect, as well as the second-best effect regarding distal particulate embolization, making it a good treatment option for patients with peripheral artery disease among the 3 DCBs evaluated in the current study. Further clinical head-to-head comparisons with larger numbers of patients are needed to explore which DCB is the most effective and safe treatment option.Clinical Impact:The findings of the current preclinical study suggests that Ranger demonstrates the strongest paclitaxel effect, as well as the second-best effect regarding distal particulate embolization making it a good treatment for patients with intermittent claudication and chronic limb-threatening ischemia.

三种紫杉醇涂层球囊治疗兔股骨腘动脉病变的生物药物效应和远端微粒栓塞的差异。
背景:最近一项随机对照试验的荟萃分析表明,与标准治疗相比,使用药物涂层球囊(DCB)治疗的患者发生大截肢的风险明显更高,尤其是使用高剂量紫杉醇涂层DCB的患者。使用DCB后出现的远端微粒栓塞被认为是导致大截肢发生率较高的潜在原因。本研究旨在从组织学和生物学角度比较 3 种 DCB(一种高剂量紫杉醇涂层 DCB [IN.PACT Admiral] 和两种低剂量紫杉醇涂层 DCB [Ranger 和 Lutonix])的生物药物效应和远端微粒栓塞情况:在 18 只兔子的健康降主动脉中充气 DCB,然后在手术 28 天后安乐死。对处理过的降主动脉和远端骨骼肌进行组织病理学评估,并测量紫杉醇浓度。Ranger治疗病变部位的紫杉醇浓度最高,其次是IN.PACT和Lutonix(Ranger vs IN.PACT vs Lutonix: 分别为1089 [745-2170] pmol/mg vs 638 [160-2075] pmol/mg vs 25 [10-304] pmol/mg;p结论:这些研究结果表明,Ranger 的紫杉醇效果最强,远端微粒栓塞效果次之,是目前研究中评估的 3 种 DCB 中治疗外周动脉疾病患者的最佳选择。临床影响:目前的临床前研究结果表明,Ranger的紫杉醇效果最强,远端微粒栓塞效果次之,是间歇性跛行和慢性肢体缺血患者的理想治疗方法。

期刊介绍: The Journal of Endovascular Therapy (formerly the Journal of Endovascular Surgery) was established in 1994 as a forum for all physicians, scientists, and allied healthcare professionals who are engaged or interested in peripheral endovascular techniques and technology. An official publication of the International Society of Endovascular Specialists (ISEVS), the Journal of Endovascular Therapy publishes peer-reviewed articles of interest to clinicians and researchers in the field of peripheral endovascular interventions.
