Pre-operative interventional radiology: could it have a role before complex laparoscopic surgery?

Abstract

Bleedings occurring during a surgical intervention can be caused by haemostatic defects, but they are generally due to ineffective local haemostasis. Current coagulation systems may not be sufficient to achieve a good haemostasis, causing, at the same time, tissue dama-ge. Furthermore, the availability of such devices does not eliminate difficulties linked to the isolation of vessels, a crucial step of surgical procedures that require the removal of an organ or part of it, in case of inflammation or neoplasm. This difficulty is even more evident, and weighs more on operative times, when the surgeon engages with video-assisted surgery, where anatomical structures are difficult to detect and the manoeuvres of dissection and separation become more complex. The use of pre-operative radio-guided embolization of organ main arterial vessels with different embolic agents, could represent a great advantage, especially for mini-invasive procedures, such as laparoscopy in patients with high bleeding risk.
