    Abstract We report the case of a 38-year-old woman who underwent orthotopic 'split' liver transplant, complicated by hepatic artery thrombosis on the first postoperative day. The patient was successfully treated with an endovascular approach by mechanical thromboaspiration of the hepatic artery, using neurovascular devices, angioplasty and stenting at the site of the surgical anastomosis.

    Abstract An 83-year-old man experienced left upper limb uncontrolled movements preceded by intense gasping during night rest, which progressed to unconsciousness and respiratory arrest requiring intubation. He was diagnosed with acute stroke due to distal occlusion of the basilar artery and received indication for endovascular thrombectomy. Standard endovascular approach includes percutaneous puncture of the femoral or radial arteries; however, the presence of unfavourable vascular anatomies (stenotic origin and tortuosity) did not allow catheterisation of the intracranial vessels through conventional access, and based on the consistent time lapse from onset of symptoms and deterioration of the clinical condition, a direct right vertebral artery ultrasound-guided puncture was performed. After one attempt of a triaxial technique, a complete recanalisation of the basilar artery and of its distal branches was achieved. Direct percutaneous puncture of the vertebral artery represents a rescue access strategy for treatment of posterior circulation stroke when other routes are not feasible.

    Abstract We have recently reported significant associations between exposure to polychlorinated biphenyls (PCB) and alterations on genome-wide methylation of leukocyte DNA of healthy volunteers and provided evidence in support of an etiological link between the observed CpG methylation variations and chronic lymphocytic leukemia. The present study aimed to elucidate the effects of PCB in human lymphocytes' methylome in vitro. Therefore, U937 cells and human peripheral blood monocytes (PBMC) were exposed in vitro to the dioxin-like PCB-118, the non-dioxin-like PCB-153, and hexachlorobenzene (HCB) and thorough cytotoxicity, genotoxicity and global CpG methylation analyses were performed. All compounds currently tested did not show any consistent significant genotoxicity at all exposure periods and concentrations used. On the contrary, extensive dose-dependent hypomethylation was observed, even at low concentrations, in stimulated PBMC treated with PCB-118 and PCB-153 as well as a small but statistically significant hypomethylation in HCB-treated stimulated cells.

    Abstract The liver is the major drug-metabolizing and drug-detoxifying organ. Many drugs can cause liver damage through various mechanisms; however, the liver response to injury includes a relatively narrow spectrum of alterations that, regardless of the cause, are represented by phlogosis, oxidative stress and necrosis. The combination of these alterations mainly results in three radiological findings: vascular alterations, structural changes and metabolic function reduction. Chemotherapy has changed in recent decades in terms of the drugs, protocols and duration, allowing patients a longer life expectancy. As a consequence, we are currently observing an increase in chemotherapy-associated liver injury patterns once considered unusual. Recognizing this form of damage in an early stage is crucial for reconsidering the therapy regimen and thus avoiding severe complications. In this frontier article, we analyze the role of imaging in detecting some of these pathological patterns, such as pseudocirrhosis, "yellow liver" due to chemotherapy-associated steatosis-steatohepatitis, and "blue liver", including sinusoidal obstruction syndrome, veno-occlusive disease and peliosis.

    Abstract Objective: This study aims to describe the results achieved in the management of rectus sheath hematoma (RSH) using glue embolization.
    Method: Data about all consecutive patients presenting with RSH, between January 2005 and December 2020 were retrospectively reviewed. RSHs were classified according to the Berna CT scan Classification. Clinical and technical outcomes were evaluated during in-hospital period and 1-month follow-up.
    Results: Among 74 patients presenting with RSH, CTA revealed an active bleeding in 61 (n = 42, 69% women; median age = 68.8 y range: 47-91). 19 cases of type 1 RSH (25.7%), under anticoagulation therapy and hemodynamically stable, were successfully managed conservatively. Conversely, endovascular embolization with cyanoacrylate glue diluted with ethiodized oil (Lipiodol Ultrafluid, Guerbet, France) was needed in n = 42 (56.8%) patients, in 16 cases after failure of conservative management; a single session of percutaneous glue embolization was adequate to achieve technical and clinical success in all patients with stabilization or progressive improvement of hemoglobin values after procedure (7.1 + 1.8 g/dL pre-procedure vs 11.1 + 1.6 g/dL post-procedure). No major complications occurred. Two minor complications were reported: 1 case (2.4%) of puncture site-related complication (local self-limiting hematoma) and 1 case (2.4%) of post-embolization syndrome (abdominal pain) spontaneously regressive. The median hospital stay was 7 d. At 30-day follow-up, 2 patients (2.7%) died of multiorgan failure.
    Conclusions: In the management of RSH, glue embolization was shown to be safe and efficacious. Glue allowed the immediate occlusion of both the "front and back doors" of bleeding without the need to reach the bleeding point, preventing potentially life-threatening recurrence.

    Abstract Purpose: Inflammatory pseudotumors of the liver (IPTL) are not exceptional benign lesions with various etiologies, histology, and imaging appearances. The incomplete knowledge of this pathology and the wide polymorphism sometimes resembling malignancy often induce long and expensive diagnostic flow, biopsy and occasionally unnecessary surgery. We propose a systematic revision of MRI literature data (2000-2021) with some narrative inserts and 10 new complete MRI cases, with the aim of organizing the data about IPTL and identifying some typical features able to improve its diagnosis from imaging.
    Methods: We performed a systematic revision of literature from 2000 to 2021 to obtain MRI features, epidemiological, and clinical data of IPTL. The basic online search algorithm on the PubMed database was "(pseudotumor) AND (liver) AND (imaging)." Quality assessment was performed using both scales by Moola for case report studies and by Munn for cross-sectional studies reporting prevalence data. A case-based retrospective study by collecting patients diagnosed with IPTL from three different university hospitals from 2015 to 2021 was done as well. Only cases with MR examinations complete with T1/T2/contrast-enhanced T1/Diffusion-Weighted (W) images and pathology-proven IPTL were selected.
    Results: After screening/selection 38 articles were included for a total of 114 patients. In our experience we selected 10 cases for a total of 16 IPTLs; 8 out of 10 patients underwent at least 1 MRI follow-up. Some reproducible and rather typical imaging findings for IPTL were found. The targetoid aspect of IPTL is very frequent in our experience (75% on T1W, 44% on T2W, 81% on contrast-enhanced T1W (at least one phase), 100% on Diffusion-W images) but is also recurrent in the literature (6% on T1W, 31% on T2W, 51% on CE-T1W (at least one phase), 18% on Diffusion-W images, and 67% on hepatobiliary phase). In our experience, Apparent Diffusion Coefficient map values were always equal to or higher than those of the surrounding parenchyma, and at MRI follow-up, nodule/s disappeared at first/second control, in six patients, while in the remaining 2, lesions persisted with tendency to dehydration.
    Conclusion: A targetoid-like aspect of a focal liver lesion must raise diagnostic suspicion, especially if IgG4-positive plasma is detected. MRI follow-up mainly shows the disappearance of the lesion or its reduction with dehydration.

    Abstract Objectives: To investigate the outcomes of patients with calcific lesions in the common femoral artery undergoing endovascular procedures with atherectomy device and scoring balloon angioplasty combined with treatment of steno-occlusive disease of the remaining arterial districts of the lower limb.
    Methods: Between January 2015 and December 2018, 11 diabetic patients at high risk for "major amputation", with calcific lesions of the common femoral artery and ischemic ulcers requiring endovascular treatment were retrospectively evaluated. Technical success was defined as revascularization of the common femoral artery with a residual stenosis lower than 30%. Primary endpoints were an immediate increase of perilesional transcutaneous oxygen pressure (TCPO
    Results: The success rate of the revascularization procedures was 100%. No patient underwent surgical conversion. One case of peri-operative bleeding at the brachial access site was observed. There were no cases of arterial dissection or undesired distal embolization. The average baseline value of perilesional TCPO
    Conclusions: Endovascular approach for severely calcified atherosclerotic lesions of the common femoral artery seems to represent a valid therapeutic option associated with promising results in terms of clinical outcome and low complication rates.

    Abstract Objective: The objective is to report a single centre experience in the embolization of visceral artery pseudoaneurysms with N-butyl-cyanoacrylate-methacryloxy sulfolane (NBCA-MS).
    Methods: A retrospective observational cohort study was conducted on data about all consecutive patients treated for visceral artery pseudoaneurysms in the Interventional Radiology Unit of SS Annunziata Hospital, in Taranto (Italy) between January 2016 and July 2020. Only patients treated with NBCA-MS embolization were included. Clinical and technical outcomes were evaluated during in-hospital stay and at 3-month follow-up by computed angiotomography (CTA).
    Results: Among 89 patients undergoing treatment for visceral artery pseudoaneurysm, a total of 58 (65.2%) patients (n = 32, 55.2% men; median age 45.8 years, range: 35-81) treated with NBCA-MS only were enrolled. Pseudoaneurysms were located in the renal artery (n = 18 cases, 31%), in the splenic artery (n = 27, 46.6%), in the intra-parenchymal hepatic artery (n = 3, 5.2%), in the common hepatic artery (n = 4, 6.9%) or in the pancreatic artery (n = 6, 10.3%). N-butyl-cyanoacrylate was diluted 1:1 with Lipiodol ultra-fluid, and mean volume injected was 0.6 ± 0.3 mL (range: 0.2-2.8 mL). Embolization was technically and clinically successful in all patients (n = 58, 100%) with an immediate total thrombosis of the pseudoaneurysm at the completion angiography. No systemic complications were noted in all cases. Five cases (8.6%) of non-target vessel embolization occurred without any clinical complication. No pseudoaneurysm recurrence was detected at the CTA control 1 day postoperatively. In one case (1.7%), a recurrence was detected 4 days after the initial treatment and successfully managed by a repeated NBCA-MS embolization. During the hospital stay, 56 patients recovered well but 2 (3.4%) died from multi-organ failure not related to the embolization. No recurrences were detected at the 3-month postoperative CTA in the remaining patients.
    Conclusions: In properly selected patients affected with visceral artery pseudoaneurysms, NBCA-MS represents a definitive and safe embolization agent.
