Persistent left superior vena cava (PLSVC) is an uncommon anomaly, estimated to be present in about 0.3\u20130.5% of healthy individuals and in about 3\u201310% of patients with congenital heart disease. It results from the failure of the left anterior cardinal vein to degenerate during embryological development. Serious complications such as shock, angina and cardiac arrest have been described during catheterization in adults with a PLSVC. Since it frequently goes undiagnosed because of lack of symptoms when not accompanied by other anomalies, variations of the superior vena cava should be considered, especially when central venous catheterization via the subclavian or internal jugular vein is difficult. The embryological development, diagnosis, and clinical implications of a PLSVC are therefore reviewed in this article.<\/jats:p>","DOI":"10.1177\/112972980901000313","type":"journal-article","created":{"date-parts":[[2018,1,24]],"date-time":"2018-01-24T11:32:05Z","timestamp":1516793525000},"page":"207-211","source":"Crossref","is-referenced-by-count":40,"title":["Persistent Left Superior Vena Cava: What the Interventional                     Nephrologist Needs to Know"],"prefix":"10.1177","volume":"10","author":[{"given":"Antonio","family":"Granata","sequence":"first","affiliation":[{"name":"Departments of Nephrology & Dialysis, Internal Medicine & Radiology, Vittorio Emanuele-Ferrarotto-S.
