Unique robotic vascular surgery procedures.

INTRODUCTION

Based on their experience with robot-assisted vascular surgery, the authors present some unique types of procedures they have performed in this area.

METHODS

From November 2005 to February 2022, a total of 560 robotic vascular procedures were performed, of which 70 were orphan operations, corresponding to 12.5%. The most common was robotic decompression of the coeliac trunk (18 times) in Dunbar syndrome, followed by robotic repair of type II endoleak after stent graft implantation (15 times) and robotic repair of splenic artery aneurysm (11 times). Less common were isolated pelvic artery aneurysm surgery (8 times), aortic thromboenderectomy and abdominal aortic patch repair (8 times) and hybrid surgery (6 times). Completely unique are renal artery reconstruction (2 times), operation of internal mammary artery aneurysm (1 time) in a patient with Marfan syndrome and paracaval biopsy (1 time) in a cancer patient.

RESULTS

In 3 cases (4.2%) the operation had to be converted to open surgery. Twice in the management of splenic artery aneurysm due to flat adhesions in the abdominal cavity and once in the endoleak operation, when due to the very fragile wall of the dilated and pulsating abdominal aortic aneurysm sac, we considered manipulation with robotic instruments to be highly risky. There was zero mortality in this cohort; one patient had to undergo laparoscopic diaphragm repair for diaphragmatic hernia at another institution after deliberation of the coeliac trunk and in one case open surgery was needed for persistent endoleak.

CONCLUSION

The use of the robotic system can be beneficial also in less frequent procedures, offering the patients all the advantages of robotic surgery. However, the need of extensive experience in robotic surgery should be emphasized because these operations are rare and perfect anatomical knowledge of the area is necessary.
