While it is often asymptomatic, it can lead to significant problems such as arrhythmias and cyanosis. Besides, it can cause serious complications during vascular interventional procedures or the surgical treatment of cardiac anomalies (CA). The clinical significance of PLSVC depends on the drainage site and the accompanying CA. In this article, we will describe the epidemiology, embryology, and anatomic variations of PLSVC. Possible accompanying CA and heterotaxy spectrum will be reviewed with the help of multidetector computed tomography (MDCT) images. Radiological pitfalls, differential diagnoses, and the clinical importance of PLSVC will be highlighted.<\/jats:p>","DOI":"10.1186\/s13244-020-00906-2","type":"journal-article","created":{"date-parts":[[2020,10,15]],"date-time":"2020-10-15T06:02:48Z","timestamp":1602741768000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":185,"title":["Persistent left superior vena cava: clinical importance and differential diagnoses"],"prefix":"10.1186","volume":"11","author":[{"given":"Aynur","family":"Azizova","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Omer","family":"Onder","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sevtap","family":"Arslan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Selin","family":"Ardali","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tuncay","family":"Hazirolan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,10,15]]},"reference":[{"key":"906_CR1","doi-asserted-by":"publisher","unstructured":"Perles Z, Nir A, Gavri S et al (2013) Prevalence of persistent superior vena cava and association with congenital heart anomalies.
