Vascular endoscopy offers a reliable, real-time method for assessing blood flow restoration during reconstructive surgery. This technique provides superior 3D lumen visualization, improving surgical outcomes and reducing the need for repeated imaging.

Area of Science:

  • Vascular Surgery
  • Minimally Invasive Techniques
  • Diagnostic Imaging

Background:

  • Intraoperative assessment of blood flow is crucial in reconstructive vascular surgery.
  • Conventional methods like angiography have limitations in real-time, detailed lumen assessment.
  • Vascular endoscopy, introduced in 1969, has seen significant improvements in recent years.

Purpose of the Study:

  • To highlight the advancements and applications of vascular endoscopy in improving intraoperative assessments.
  • To compare the advantages of vascular endoscopy over traditional methods like angiography.
  • To demonstrate the utility of vascular endoscopy in various vascular surgical procedures.

Main Methods:

  • Vascular endoscopy requires temporary blood flow interruption, saline perfusion for visualization, and specialized endoscopes.

  • Utilizes small-calibre endoscopes (1.7-2.7 mm diameter) for access to various vessel sizes.
  • Applications include thromboendarterectomy, embolectomy, graft surveillance, and thrombectomy.

    • Main Results:

    • Vascular endoscopy provides reliable, three-dimensional lumen control.
    • It offers advantages over angiography, including ease of use, time savings, and avoidance of X-ray exposure.
    • Enables immediate diagnosis and correction of technical faults or missed vascular lesions.

    Conclusions:

    • Vascular endoscopy is a valuable tool for intraoperative assessment in vascular surgery.
    • Its improved technology and small-calibre instruments expand its application to smaller vessels.
    • It enhances surgical precision, patient safety, and potentially reduces complications.
