Area of Science:

  • Neurosurgery
  • Vascular Surgery
  • Medical Simulation

Background:

  • Microsurgical cerebrovascular thrombectomy for stroke is underreported.
  • This technique offers potential as a primary or salvage treatment.
  • High skill is required, necessitating effective training methods.

Purpose of the Study:

  • To describe and validate an ex vivo simulator for stroke microsurgical thrombectomy.
  • To analyze operative nuances for improved training.

Main Methods:

  • Human placenta models simulated middle cerebral artery vessels with thrombus.
  • Neurosurgeons performed arteriotomies to excise thrombus.
  • Construct validity assessed task completion, vessel cleaning, stenosis, and leakage.

Main Results:

  • Human placenta models accurately replicated stroke microsurgical thrombectomy.
  • Transverse 1-mm arteriotomy yielded optimal results (P < 0.05).
  • This technique ensured complete thrombus removal, reduced stenosis, and minimized leakage.

Conclusions:

  • A human placenta simulator effectively reproduces stroke microsurgical thrombectomy tasks.
  • Transverse 1-mm arteriotomy followed by thrombectomy and sutures meets quality assurance standards.
  • This approach facilitates vessel opening, complete thrombus removal, and faster microsuture.
