Perioperative and oncologic outcomes of open radical nephrectomy and inferior vena cava thrombectomy with liver mobilization and Pringle maneuver for Mayo III level tumor thrombus: single institution experience.

Background: Scarce data are available regarding the technique and outcomes for patients with RCC and Mayo III caval thrombi. The aim of this study was to report surgical and oncological outcomes of RCC patients with Mayo III thrombi treated with radical nephrectomy and thrombectomy after liver mobilization (LM) and Pringle maneuver (PM).

Methods: Retrospective analysis of surgical technique, outcomes and cancer control in 19 patients undergoing LM and PM in a single tertiary care institution were analyzed.

Comparison between percutaneous and laparoscopic microwave ablation of hepatocellular carcinoma.

Based on patient and tumor characteristics, some authors favor laparoscopic microwave ablation (LMWA) over the percutaneous approach (PMWA) for treatment of hepatocellular carcinoma (HCC). We compared the two techniques in terms of technique efficacy, local tumor progression (LTP) and complication rates. A retrospective comparative analysis was performed on 91 consecutive patients (102 HCC tumors) who underwent PMWA or LMWA between October 2014 and May 2019.

Covered stenting and transcatheter embolization of splenic artery aneurysms in diabetic patients: A review of endovascular treatment of visceral artery aneurysms in the current era.

Diabetes mellitus is associated with both microvascular and macrovascular complications, which can result in visceral aneurysms as for example splenic artery aneurysms: in their management, an endovascular treatment, less invasive than surgery, is generally preferred. Endovascular treatment of splenic artery aneurysms can be based either on covered stenting (CS) or transcatheter embolization (TE). CS generally allows aneurysm exclusion with vessel preservation, while TE usually determines target artery occlusion with potential risk of distal ischemia.

Endovascular Repair of 40 Visceral Artery Aneurysms and Pseudoaneurysms with the Viabahn Stent-Graft: Technical Aspects, Clinical Outcome and Mid-Term Patency.

Purpose: Endovascular repair of true visceral artery aneurysms (VAAs) and pseudoaneurysms (VAPAs) with stent-grafting (SG) can simultaneously allow aneurysm exclusion and vessel preservation, minimizing the risk of ischemic complications. Our aim was to report a single-center experience on SG of visceral aneurysms, focusing on technical aspects, clinical outcome and mid-term patency.

Materials And Methods: Consecutive patients affected by VAAs-VAPAs and submitted to endovascular treatment were retrospectively reviewed, and SG cases with the self-expandable peripheral Viabahn stent-graft were analyzed (2003-2017).

Endovascular Treatment of Visceral Artery Aneurysms and Pseudoaneurysms in 100 Patients: Covered Stenting vs Transcatheter Embolization.

Purpose: To retrospectively report a large single-center experience of visceral artery aneurysms (VAAs) and pseudoaneurysms (VAPAs) treated with covered stenting (CS) as the first therapeutic option vs transcatheter embolization (TE).

Methods: One hundred patients (mean age 59±14 years; 58 men) underwent 59 elective and 41 emergent endovascular procedures to treat 51 VAAs and 49 VAPAs. Seventy patients had TE and 30 received CS (27 Viabahn and 3 coronary stent grafts).

Microwave ablation of liver malignancies: comparison of effects and early outcomes of percutaneous and intraoperative approaches with different liver conditions : New advances in interventional oncology: state of the art.

Liver thermal ablation is an alternative treatment for hepatocellular carcinoma (HCC) and secondary liver malignancies. Microwave ablation (MWA) produces large ablation zones (AZ) in short time; however, AZ prediction is based on preclinical ex vivo models, rising concerns about reproducibility and safety in humans. We aimed to investigate the effects produced by a new-generation MWA system on human liver in vivo with different approaches (percutaneous or intraoperative) and liver conditions (cirrhosis or previous chemotherapy treatment), in comparison with manufacturer-provided predictions based on ex vivo animal models.

Technique, complications, and therapeutic efficacy of percutaneous transplantation of human pancreatic islet cells in type 1 diabetes: the role of US.

Purpose: To retrospectively evaluate the role of ultrasonography (US) with regard to the technique, complications, and therapeutic efficacy of percutaneous intrahepatic transplantation of human pancreatic islet cells with combined US and fluoroscopic guidance.

Materials And Methods: The institutional review board approved the study, and informed consent was obtained from all patients. After kidney transplantation, 34 uremic diabetic patients (20 men, 14 women; mean age, 40.

Complications after percutaneous transaxillary implantation of a catheter for intraarterial chemotherapy of liver tumors: clinical relevance and management in 204 patients.

Objective: The purposes of the study were to evaluate the complications of patients who underwent percutaneous transaxillary implantation of a permanent catheter-port system for intraarterial hepatic chemotherapy and determine their clinical relevance and specific management. SUBJECTS AND METHODS. Catheter-port systems were placed in 204 patients with liver tumors (86.

Successful endovascular treatment for gastroduodenal artery pseudoaneurysm with an arteriovenous fistula after pancreas transplantation.

The aim of this study was to demonstrate the usefulness of endovascular treatment for gastroduodenal artery pseudoaneurysm with an arteriovenous fistula after simultaneous pancreas-kidney transplantation. We describe the case of a 38-year-old man who underwent successful simultaneous pancreas-kidney transplantation. An asymptomatic pseudoaneurysm of the donor gastroduodenal artery with an arteriovenous fistula was incidentally diagnosed by routine color flow Doppler ultrasound (CDU) examination and confirmed by 3-D gadolinium-enhanced magnetic resonance angiography (MRA) 15 days after transplantation.

Hemorrhage from a right hepatic artery pseudoaneurysm: endovascular treatment with a coronary stent-graft.

Purpose: To report a novel case demonstrating the successful endovascular treatment of a right hepatic artery pseudoaneurysm using a balloon-expandable coronary stent-graft.

Case Report: A 60-year-old woman underwent surgical treatment for a Klatskin tumor, but her postoperative course was complicated by serious blood loss. An emergent celiac angiogram through a right transfemoral approach demonstrated a small iatrogenic pseudoaneurysm in the proximal right hepatic artery.

Percutaneous vs. surgical placement of hepatic artery indwelling catheters for regional chemotherapy.

Background/aims: Intra-arterial hepatic chemotherapy based on floxuridine infusion is an effective treatment for hepatic metastases from colorectal cancer. The aim of the present study is the comparative analysis of surgical and percutaneous transaxillary approaches to implant a catheter into the hepatic artery for intra-arterial hepatic chemotherapy with floxuridine.

Methodology: Fifty-six patients received an arterial device for intra-arterial hepatic chemotherapy.
