Area of Science:

  • Vascular surgery
  • Interventional radiology
  • Medical device technology

Background:

  • Vascular interventions like angioplasty and fibrinolysis are crucial for treating occlusive lesions.
  • Accurate visualization of vascular structures and procedural changes is essential for successful interventions.
  • Current imaging modalities may have limitations in visualizing fine details during intravascular procedures.

Purpose of the Study:

  • To evaluate the efficacy of a combined endoscope and high-pressure saline irrigation system for vascular interventions.
  • To assess the utility of vascular endoscopy in guiding and monitoring aneurysm occlusion and vascular lesion treatment.
  • To compare the visualization capabilities of endoscopy with traditional angiography.

Main Methods:

Related Experiment Videos

  • A combined system of an endoscope and high-pressure saline irrigation was utilized.
  • The system was tested for occlusion of experimental aneurysms.
  • Angioplasty and fibrinolysis of canine femoral artery occlusive lesions were performed using the system.
  • Endoscopic visualization was compared with angiographic findings.

    • Main Results:

    • Endoscopy provided detailed visualization of the aneurysmal orifice and lumen, aiding balloon placement and detachment.
    • The system facilitated visualization of dynamic changes during thrombolysis.
    • Endoscopy revealed fine intimal injuries from angioplasty that were not visible on angiography.
    • Vascular endoscopy proved valuable for pre-, intra-, and postoperative assessment.

    Conclusions:

    • The combination of endoscope and high-pressure saline irrigation is effective for aneurysm occlusion and treating vascular occlusive lesions.
    • Vascular endoscopy offers superior visualization of procedural details compared to angiography.
    • Vascular endoscopy is a valuable tool for comprehensive evaluation of intravascular interventions.
