Aims: Long-term freedom from atrial fibrillation (AF) after catheter ablation (CA) and consequently the potential for stroke reduction remain unpredictable. Percutaneous left atrial appendage closure (LAAC) is an effective mechanical alternative to oral anticoagulation (OAC) for stroke prevention in AF patients. This study aims to evaluate long-term clinical results of combined CA and LAAC in one single procedure. Methods and results: Patients with non-valvular AF who underwent combined CA and LAAC procedure were included in the retrospective compilation of independent prospective general LAAC registries at the individual centres...

BACKGROUND: Differentiation between normal renal cellular structures and renal tumors can be a diagnostic challenge during fine needle aspiration. It is of particular relevance during percutaneous thermal ablation because of the small size of tumors and when performing rapid on-site evaluation. METHODS: A cyto-histological correlation study assisted by immunocytochemistry was performed. The study was based on 10 nephrectomy specimens. For the identification of proximal tubular cells we used CD10 and α-methylacyl coenzyme A racemase (AMACR)...

A 70-years-old male with a history of hypertension and drug resistant paroxysmal atrial fibrillation (AF) presented to our hospital for catheter ablation to his symptomatic AF. He had no prior surgical or percutaneous procedure to close or exclude the left atrial appendage (LAA). A transesophageal echocardiography (TEE) was performed to rule out intra-cardiac thrombus prior to the ablation procedure. Although the TEE imaging at multiple acquisition angles was obtained, the LAA could not be visualized and an absence of the LAA was suspected...

Thermal ablation is an alternative treatment for colorectal cancer liver metastasis (CRLM). However, prognostic factors in patients with CRLM who have undergone microwave ablation (MWA) have not been clearly defined. Therefore, this study aimed to analyze the risk factors associated with early recurrence in patients with CRLM treated with MWA.Herein, we retrospectively analyzed data for 140 patients with CRLM who underwent MWA from 2013 to 2015 in our institution. Patients were grouped by median pretreatment carcinoembryonic antigen (CEA) level into the high CEA level (>3...

BACKGROUND: When a major hepatic resection is necessary, sometimes the future liver remnant is not enough to maintain sufficient liver function and patients are more likely to develop liver failure after surgery. AIM: To test the hypothesis that performing a percutaneous radiofrecuency liver partition plus percutaneous portal vein embolization (PRALPPS) for stage hepatectomy in pigs is feasible. METHODS: Four pigs (Sus scrofa domesticus) both sexes with weights between 25 to 35 kg underwent percutaneous portal vein embolization with coils of the left portal vein...

Uterine fibroids are the most common benign pelvic tumor of the female genital tract and tend to increase with age; they cause menorrhagia, dysmenorrhea, pelvic pressure symptoms, back pain, and subfertility. Currently, the management is based mainly on medical or surgical approaches. The nonsurgical and minimally invasive therapies are emerging approaches that to the state of the art include uterine artery embolization (UAE), image-guided thermal ablation techniques like magnetic resonance-guided focused ultrasound surgery (MRgFUS) or radiofrequency ablation (RF), and percutaneous microwave ablation (PMWA)...

Objective: Cryoablation of renal tumors adjacent to the ureter or pelvicalyceal system carries risks for thermal injury of the collecting system. Although cold antegrade perfusion has been described for radiofrequency ablation, warm saline perfusion for renal cryoablation has not been well-characterized. The purpose of this study was to determine the safety and feasibility of antegrade and retrograde warm saline perfusions during percutaneous renal cryoablation. Material and methods: A retrospective review was performed on 136 patients treated with percutaneous renal cryoablation at a single academic institution between 2009 and 2015...

BACKGROUND: Radiofrequency ablation is the recommended treatment for patients with hepatocellular carcinoma who have lesions smaller than 3 cm and are therefore not candidates for surgery. Microwave ablation is a more recent technique with certain theoretical advantages that have not yet been confirmed clinically. We aimed to compare the efficacy of both techniques in the treatment of hepatocellular carcinoma lesions of 4 cm or smaller. METHODS: We did a randomised controlled, single-blinded phase 2 trial at four tertiary university centres in France and Switzerland...

Open saphenous removal, phlebectomy, and venous ligation were historic mainstays of surgical treatment of venous disease. Duplex ultrasound has become standard to diagnose venous insufficiency. Percutaneous modalities have allowed treatments to include thermal and nonthermal endovenous ablation. These treatments vary in preoperative planning, procedural steps, and postprocedural care, but all are safe and effective. An individualized approach should be taken in determining which modality is offered to each patient...
