Tricuspid regurgitation is considered to be the main cause of RPF in patients with chronic heart disease, but the precise pathomechanism of this PV flow pattern has not yet been resolved. We descibe for the first time a RPF of the PV in a young patient with a mediastinal haematoma after inadvertent puncture of the subclavian artery. In this patient, transcutaneous echocardiography demonstrated normal valves without any tricuspid regurgitation as well as normal diameters of the cardiac cavities. The RPF of the PV in this patient resolved spontaneously within 7 days. An increased hepatic outflow resistance with transmission of hepatic artery pulsations across arterioportal communications seems the most likely pathomechanism to explain our finding.<\/jats:p>","DOI":"10.1259\/bjr.74.886.740962","type":"journal-article","created":{"date-parts":[[2014,6,13]],"date-time":"2014-06-13T02:13:40Z","timestamp":1402625620000},"page":"962-964","source":"Crossref","is-referenced-by-count":3,"title":["Reversed portal vein pulsatility on Doppler ultrasound secondary to an iatrogenic mediastinal haematoma"],"prefix":"10.1093","volume":"74","author":[{"given":"C","family":"Go\u0308rg","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B","family":"Wollenberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J","family":"Beyer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2014,3,5]]},"reference":[{"key":"2025060608115827000_R1","doi-asserted-by":"crossref","unstructured":"Taylor KJ, Burns PN, Woodcock JP, Wells PN.
