Summary
This study introduces videoendoscopic vascular surgery for aortoiliac occlusive disease, showing promising results in animal models. Further research is needed to optimize this minimally invasive approach for potential clinical use.
Area of Science:
- Vascular Surgery
- Minimally Invasive Surgery
- Endoscopic Techniques
Background:
- Conventional surgery for aortoiliac occlusive disease carries risks of postoperative complications.
- A novel videoendoscopic approach for infrarenal aortoiliacal artery surgery was developed to mitigate these risks.
Purpose of the Study:
- To evaluate the feasibility and efficacy of a new videoendoscopic vascular surgery technique.
- To assess the safety and patency of videoendoscopic aortofemoral bypass grafting and iliac patchplasty in an animal model.
Main Methods:
- Development of specialized instruments for endoscopic vascular surgery.
- Acute and long-term animal studies in piglets (32 +/- 2 kg) using the developed techniques.
- Ultrasonic monitoring of femoral artery blood flow and evaluation of systemic/hemodynamic parameters.
Main Results:
- Positive outcomes observed in ultrasonically monitored blood flow and hemodynamic parameters post-videoendoscopic reconstruction.
- All animals in long-term studies (2-7 weeks post-aortofemoral bypass grafting) showed positive recovery.
- Angiographic examination confirmed the patency of the prostheses.
Conclusions:
- The endoscopic vascular method can be performed adhering to conventional surgical standards.
- Further research and instrument development are essential to optimize this innovative surgical approach.
- Ongoing long-term animal studies aim to refine and validate the videoendoscopic technique.
