Insights

This study presents a novel technique for treating challenging peripheral chronic total occlusions (CTOs) using a readily available guidewire. This method offers a cost-effective alternative when advanced devices are inaccessible, though it carries a risk of distal atheroembolism.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Medical Devices

Background:

  • Peripheral chronic total occlusions (CTOs) present significant challenges in endovascular interventions.
  • Existing techniques and devices for CTO crossing are often expensive and not universally accessible.
  • There is a need for cost-effective and readily available methods to improve CTO recanalization success rates.

Purpose of the Study:

  • To describe a novel, cost-effective technique for crossing calcified peripheral CTOs.
  • To evaluate the feasibility of using the stiff end of a Terumo glidewire for recanalization.
  • To report the outcomes and potential risks associated with this sharp recanalization method.

Main Methods:

  • The study involved two cases of peripheral CTO recanalization.
  • The stiff end of a Terumo glidewire was utilized to penetrate and cross the occlusions.
  • This technique was employed when conventional methods failed and advanced devices were unavailable.

Main Results:

  • Successful recanalization of peripheral CTOs was achieved in both reported cases using the glidewire technique.
  • The method proved effective for crossing calcified lesions.
  • A potential risk of distal atheroembolism was noted as a complication.

Conclusions:

  • Sharp recanalization with the stiff end of a Terumo glidewire is a viable technique for peripheral CTOs.
  • This approach offers a practical solution for calcified CTOs when advanced, costly devices are not accessible.
  • Clinicians must be aware of and manage the associated risk of distal atheroembolism.
