Pre-operative interventional radiology: could it have a role before complex laparoscopic surgery?
2021
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 …
Image-Guided Mini-Invasive Treatments for Vascular and Oncologic Diseases: Embolization Therapy
2020
Transcatheter Embolization, also called Embolotherapy, is a mini-invasive, non-surgical therapeutic solution used in Interventional Radiology to close blood vessels deliberately. A wide range of embolic agents is available in clinical practice, including metal coils and liquid agents. More recent advances in biomaterials such as shape-memory foam and in-situ gelling solutions have led to the development of new pre-clinical embolic agents. This review offers a brief overview of current and emerging technologies in the field of endovascular embolization. The focus is on devices, materials and techniques.
