“…The largest lesion diameter is calculated on the tumor portion that appears “vital” ( Table 1 ) [ 34 ]. The viable tumor ( Figure 1 ) can be assessed with protocols including a combination of arterial, portal venous and delayed phase, based on the tumor (e.g., should be measured during the arterial phase for hypervascular tumors and on portal phase for hypovasular tumors) [ 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ].…”

Background: Imaging methods and the most appropriate criteria to be used for detecting and evaluating response to oncological treatments depend on the pathology and anatomical site to be treated and on the treatment to be performed. This document provides a general overview of the main imaging and histopathological findings of electroporation-based treatments (Electrochemotherapy—ECT and Irreversible electroporation—IRE) compared to thermal approach, such as radiofrequency ablation (RFA), in deep-seated cancers with a particular attention to pancreatic and liver cancer. Methods: Numerous electronic datasets were examined: PubMed, Scopus, Web of Science and Google Scholar. The research covered the years from January 1990 to April 2021. All titles and abstracts were analyzed. The inclusion criteria were the following: studies that report imaging or histopathological findings after ablative thermal and not thermal loco-regional treatments (ECT, IRE, RFA) in deep-seated cancers including pancreatic and liver cancer and articles published in the English language. Exclusion criteria were unavailability of full text and congress abstracts or posters and different topic respect to inclusion criteria. Results: 558 potentially relevant references through electronic searches were identified. A total of 38 articles met the inclusion criteria: 20 studies report imaging findings after RFA or ECT or IRE in pancreatic and liver cancer; 17 studies report histopathological findings after RFA or ECT or IRE; 1 study reports both imaging and histopathological findings after RFA or ECT or IRE. Conclusions: Imaging features are related to the type of therapy administrated, to the timing of re-assessment post therapy and to the imaging technique being used to observe the effects. Histological findings after both ECT and IRE show that the treated area becomes necrotic and encapsulated in fibrous tissue, suggesting that the size of the treated lesion cannot be measured as an endpoint to detect response. Moreover, histology frequently reported signs of apoptosis and reduced vital tissue, implying that imaging criteria, which take into account the viability and not the size of the lesion, are more appropriate to evaluate response to treatment.

“…The main concern about the presented post-surgical pseudoaneurysm was the proximity with coronary ostia that makes an interventional treatment more complex and rules out the possibility of deploying an endograft because the proximal landing zone does not have enough length and safety. Previously, several reports have shown the feasibility and safety of percutaneous embolization of aneurysm and pseudoaneurysm in cerebrovascular and peripheral interventions [2][3][4].…”

A 45 years old man underwent a surgical replacement of ascending aorta and aortic arch for a type A aortic dissection. A 3 months CT follow-up documented a significant pseudoaneurysm close to the aortic root. A percutaneous intervention was successfully performed with the deployment of four Penumbra Coil inside the pseudoaneurysm, ensuring a proper exclusion as highlighted in long-term CT follow-up.

“…Only embolization of hilar or intraparenchymal aneurysms with vessel sacrifice can cause splenic infarcts which are usually limited, not clinically significant and managed conservatively. Coil packing density is crucial to prevent aneurysm revascularization [ 109 ]. To enhance the embolic effect in large vessel such as splenic arteries, coils have been associated with adhesive or non-adhesive liquid embolic agents, like glue [ 110 ] and Squid [ 68 ].…”

Visceral artery aneurysms (VAAs) are rare, usually asymptomatic and incidentally discovered during a routine radiological examination. Shared guidelines suggest their treatment in the following conditions: VAAs with diameter larger than 2 cm, or 3 times exceeding the target artery; VAAs with a progressive growth of at least 0.5 cm per year; symptomatic or ruptured VAAs. Endovascular treatment, less burdened by morbidity and mortality than surgery, is generally the preferred option. Selection of the best strategy depends on the visceral artery involved, aneurysm characteristics, the clinical scenario and the operator’s experience. Tortuosity of VAAs almost always makes embolization the only technically feasible option. The present narrative review reports state of the art and new perspectives on the main endovascular and other interventional options in the treatment of VAAs. Embolization techniques and materials, use of covered and flow-diverting stents and percutaneous approaches are accurately analyzed based on the current literature. Visceral artery-related considerations and targeted approaches are also provided and discussed.
