BACKGROUND: Pulmonary artery (PA) @entity439 are rare and their related complications like dissection or @entity397 have been so far reported in a few reports, and a systematic description of the disease is lacking. To identify @entity1 with PA @entity439 , at high-risk for complications, is critical. We performed a systematic review of the literature to determine characteristics that could identify high-risk @entity1 . METHOD: A systematic search strategy was established and executed in Pubmed, Embase, Cochrane Central Register of Controlled Trials and Google scholar. Case reports were included if a minimal set of data were described. RESULTS: After executing the search strategy and exclusion of non-relevant or duplicate articles, 38 original articles, reviews and 169 case reports could be included. Articles were classified in high and low-pressure PA @entity439 and subdivided in six groups on basis of the causative mechanisms. PA dilatation was most common in association with @entity120 , but only one dissection was reported in 6 original articles containing 153 @entity1 . Analysis of the case reports suggests that predictors of high-risk @entity1 are: @entity120 in @entity299 , fast PA diameter growth (>2 mm/year), tissue weakness due to @entity281 and possibly pregnancy especially in combination. Except for 2 cases, PA dissection did not occur, when the PA diameter was <75 mm and the PA pressure <50 mmHg. CONCLUSION: High-risk PA @entity439 maybe identified by evaluating: the causative mechanism(s) for PA dilatation, absolute PA diameter and growth rate and by evaluating the PA systolic pressure.
