Robot-assisted endovascular treatment of hepatic artery aneurysm: A case report.

Objective: Robot-assisted endovascular surgery has emerged as a new alternative to interventional procedures, with its application expanding to peripheral and visceral approaches. The objective of this paper is to describe a robot-assisted endovascular treatment in splanchnic arteries.

Methods: A case report of an asymptomatic male patient with an incidental finding of a saccular aneurysm of the proper hepatic artery measuring 3.7 × 2.7 cm and distant 0.6 cm from the origin of the gastroduodenal artery.

Results: Using a robot-assisted endovascular technique CorPath GRX platform - Siemens), 2 guidewires were advanced in parallel: the first one was placed inside the aneurysm sac, while the second one was placed in the proper hepatic artery distal to the aneurysm; through the first guidewire, a balloon was advanced, positioned distally to the aneurysm, and through the second one, a microcatheter was advanced. Embolization of the aneurysm was performed with the use of coils and Onyx. Control exam performed 120 days after embolization revealed treated aneurysm and preserved distal arterial flow.

Conclusion: Using a robotic platform for navigation in splanchnic territory is safe and effective.
