[Rotational atherectomy for acute and chronic lower limb ischemia]

Area of Science:

• Vascular Surgery
• Endovascular Interventions
• Peripheral Arterial Disease

Background:

• Rising living standards correlate with increased incidence of diabetes, atherosclerosis, and hypertension, leading to more lower extremity arterial ischemic lesions.
• Lower extremity ischemia presents a significant challenge in vascular surgery, with traditional treatments like bypass surgery and thrombectomy having limitations.
• Despite advances, lower extremity ischemia is associated with high rates of morbidity, mortality, and limb loss, necessitating early diagnosis and prompt intervention.

Purpose of the Study:

• To review modern studies and clarify the effectiveness of innovative rotational atherectomy systems in treating acute and chronic lower limb ischemia.
• To summarize current evidence on the efficacy of rotational atherectomy for peripheral vascular disease.

Main Methods:

• Systematic review of recent studies on rotational atherectomy systems (Rotarex, Jetstream).
• Analysis of clinical outcomes related to blood circulation restoration in lower limb ischemia.
• Evaluation of safety and efficacy data from various patient cohorts.

Main Results:

• Rotarex and Jetstream rotational atherectomy systems demonstrate effectiveness in restoring blood circulation for chronic thrombosis, particularly in atherosclerotic and diabetic arterial lesions.
• These systems are recommended for patient use, considering specific indications and individual lesion characteristics.
• Studies confirm the safety and efficacy of rotational atherectomy, but highlight the need for careful patient selection.

Conclusions:

• Rotational atherectomy is a viable option for managing chronic lower limb ischemia, offering effective blood flow restoration.
• Careful patient selection and further large-scale studies are crucial to optimize the use of rotational atherectomy and address existing limitations.
• Continued research is essential to fully establish the long-term benefits and refine the application of these innovative endovascular technologies.
