External iliac arterial dissection after robot-assisted radical cystectomy with an intracorporeal ileal conduit and extended pelvic lymph node dissection

Introduction: External iliac arterial dissection after robot-assisted laparoscopic procedures is an extremely rare complication. It may cause severe adverse outcomes, such as lower limb necrosis.

Case presentation: A 73-year-old man was diagnosed with cT2 ≤ N0M0 bladder cancer and underwent robot-assisted radical cystectomy. After surgery, he complained of severe left lower leg pain. Computed tomography showed external iliac arterial occlusion. Furthermore, the emergency operation revealed external iliac arterial dissection and occlusion.

Conclusion: The robot arm does not have any sense of force or touch. Thus, it is necessary to pay sufficient attention to the traction of blood vessels and contact with major organs.
