When approaching a palpable mass in the upper limbs, the possibility of a peripheral nerve tumour should always be considered. It is important to look for typical signs of schwannomas, such as a positive Tinel sign and peripheral paraesthesia. Imaging assessment with magnetic resonance imaging (MRI) and ultrasonography enables the determination of where the tumour takes its origin and from which nerve. Microsurgical techniques and know-how are recommended in approaching the resection in order to respect as many nerve fibres as possible.

In prospective, non-randomized study of patients with cirrhosis, we found under-dilation of PTFE-SGs during TIPS placement to be feasible, associated with lower rates of PSE, and effective.

Total-body three-dimensional (3D) MRA allows a fast, safe, and accurate assessment of the arterial system in patients with arteriosclerosis and can be considered an alternative to DSA in the management of patients with steno-obstructive disease of the peripheral arteries.

Peripheral Nerve Sheath Tumors (PNSTs) are extremely uncommon and it is almost certain that no individual upper limb surgeon will gain great experience in a lifetime with these lesions. Benign and malignant PNSTs are separately analyzed in this descriptive review and discussed focusing the attention towards the most important features. A comprehensive and summarized overview of this topic is offered to the reader in order to improve the complex management of these tumors from diagnosis to treatment. A systematic search in PubMed was carried out using the keywords (and synonyms) written below in order to find relevant and most cited papers. Reckoning the rarity of the pathology, few selected case reports were taken into account. A compendium of each PNST was created to sum up the personal experience of the Authors who wrote the articles, critically inspected and analyzed. Every section of the paper is meant to provide useful tips to the reader.

Persistent left superior vena cava (SVC) is a rare congenital malformation of the thoracic venous system. We report a case involving a 7-year-old boy, who was admitted to our CT scanning room because of an incidental discovery of low blood-oxygen levels (90–94% in good health). A persistent left SVC was depicted, with drainage in the left atrium and a resultant right-to-left shunt;right SVC was present, draining to the right atrium. A small bridging vein was depicted. A comprehensive cardiological assessment with echocardiography was performed, but no other anomalies were found. He was successfully treated with a percutaneous endovascular approach and vascular plug deployment. A complete occlusion of the left SVC was obtained, with normalization of the oxygen saturation. Persistent left SVC is a rare vascular anomaly, often incidentally detected. Physicians should be aware because it may have significant clinical implications, especially during catheterization procedures or when associated with other cardiac malformations.
