Percutaneous trans-hepatic rescue and neo-creation of a post-surgical complete hepaticojejunostomy dehiscence.

Biliary leakage complicating hepaticojejunostomy is a therapeutic dilemma for surgeons, gastroenterologist, and interventional radiologist. It is a major cause of postoperative morbidity. Percutaneous biliary intervention techniques have been developed for treating benign post-surgical biliary disease in patients not having severely compromised clinical conditions. Interventional radiology manoeuvres are especially indicated as the first line of treatment if endoscopic procedures are unfeasible for patients due to postsurgical anatomical modifications. We present a case of post-surgical complete hepaticojejunostomy dehiscence that was treated totally by percutaneous techniques with trans-hepatic rescue and hepaticojejunostomy neo-creation.

Hepatic artery aneurysms: Endovascular therapeutic techniques.

Hepatic Artery Aneurysm (HAA) is a rare disease, but it can be a life-threatening pathology if it is ruptured. Multi-Detector Computed Tomography has to be considered the "gold standard" diagnostic imaging in detecting HAA and it is essential for treatment planning. Treatment for HAA can be surgical or endovascular. Endovascular approaches in HAA, compare to conventional abdominal surgery, benefit in less invasive treatments. The aim of our paper is to emphasize the three possible endovascular therapeutic techniques in HAA: packing embolization, isolation embolization and stenting deployment.

Non-invasive removal of self-locking entrapped nephrostomy tubes.

INTRODUCTION: The removal of an encrusted nephrostomy tube can be a challenging maneuver. Urological literature is very bare in detailing techniques for removal of entrapped percutaneous catheters. We present a simple, safe and non-invasive technique of nephrostomy removal using a vascular introducer sheath, useful to manage complicated situations such as nephrostomies blocked for severe encrustations or disabled in their self-locking system. SURGICAL TECHNIQUE: The nephrostomy tube is cut and the stump is passed with a suture needle. The suture is passed through the inner vascular introducer sheath tip, and the introducer is then removed. The introducer sheath is advanced over the nephrostomy until joining the pigtail segment, under fluoroscopy guidance. Thus the suture is pulled out with strenght to contrast the opposite stiffness of the encrusted coil, until the nephrostomy has safely come out. COMMENT: The sheath exchange technique is quick, involves less manipulation through the perirenal fascia and kidney, and is suitable for different conditions of entrapped nephrostomies.

Percutaneous management of bone metastases: state of the art, interventional strategies and joint position statement of the Italian College of MSK Radiology (ICoMSKR) and the Italian College of Interventional Radiology (ICIR).

Interventional radiology provides local management of bone metastases (BM) with a palliative intent in most cases, or with a curative intent in selected patients. Its role has rapidly expanded in the last decade, offering new treatment solutions often in combination with surgery, radiation therapy and medical treatments. The aim of the present paper is to increase awareness, acceptance and adoption of interventional radiology procedures for the treatment of BM; and to present the joint position of the Italian College of Musculoskeletal Radiology and the Italian College of Interventional Radiology.

Which needle in the treatment of thyroid nodules?

Thyroid nodules are a common finding in general population, with a prevalence of 20% to 70% at ultrasound (US) examination. Many of them are benign but treatment can be necessary to relief compressive symptoms. In the last years, percutaneous ablations have achieved amazing development in the treatment of thyroid nodules as they provide a minimally invasive but effective approach. We aimed to summarize the main aspects related to treatment of thyroid nodules with radiofrequency ablation (RFA), focusing on the use of different types of needles. A narrative review was performed and all papers analyzed reported good results in terms of nodule's size reduction and symptoms relief. No major complications have been reported, even though needles of bigger size seemed related with major risks of post-procedural local edema. Thus, thinner internally cooled multi tined needles [18-19 Gauge (G)] rather than larger needles (14 G) seem to have better results and less complications.
