In presence of a normally developed system of the deep collecting veins of the lower limb and within the pelvic outflow we are talking about a persisting marginal vein (MV). Hypoplasia or even aplasia of the main deep veins in contrary defines the persisting embryonal vein (EV). Already in childhood these truncular dysplastic veins tend to develop varicose enlargement, causing severe reflux of a huge volume of blood \u2013 even more when being associated with av-fistulas (46%). In consequence a rapidly growing chronic venous insufficiency will guide to additional injuries. Patients and results: We have analysed 97 patients showing a persisting MV (n: 92 ) within a total of 102 legs. A persistent embryonal vein (EV) was seen 10 times within this clientel. The persisting truncular veins, associated with phlebectasias and typical clinical symptoms have been examined in a diagnostic \u201cstep-by-step\u201d procedure, mainly phlebographically (ascending leg phlebography and varicography), including direct venous blood pressure measurements (phlebodynamometry) and \u2013 if needed \u2013 by arteriography, showing av-shunting fistulae in 46% of cases. CT and MRI were consulted for the exact therapy planing (frequently initially offered as a non-invasive, however, inadequate key of diagnostic). Actually now these techniques cannot replace pre-operatively the angiographic imaging techniques. Conclusions: The analysis of clinical, morphologic and functional signs, guiding to a specific therapy-relevant classification of MV\u2019s and EV\u2019s will be presented. And a specific strategy of surgical repair, interventional treatment of av-fistulas and conservative compressive follow-up treatment attempting palliative recompensation of the diseased venous outflow will be discussed also. <\/jats:p>","DOI":"10.1024\/0301-1526.35.2.67","type":"journal-article","created":{"date-parts":[[2006,6,1]],"date-time":"2006-06-01T02:42:49Z","timestamp":1149129769000},"page":"67-77","source":"Crossref","is-referenced-by-count":13,"title":["Congenital vascular malformations: The persistence of marginal and embryonal veins"],"prefix":"10.1024","volume":"35","author":[{"family":"Weber","sequence":"first","affiliation":[{"name":"Diagnostische Angiologie und Inventions-Radiologie, Klinik Dr. Guth, Hamburg"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Daffinger","sequence":"additional","affiliation":[{"name":"Handchirurgie, Diakonie-Klinikum Hamburg-Elim, Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"101","container-title":["Vasa"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/econtent.hogrefe.com\/doi\/pdf\/10.1024\/0301-1526.35.2.67","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,5,8]],"date-time":"2022-05-08T10:20:16Z","timestamp":1652005216000},"score":1,"resource":{"primary":{"URL":"https:\/\/econtent.hogrefe.com\/doi\/10.1024\/0301-1526.35.2.67"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2006,5,1]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2006,5,1]]}},"alternative-id":["10.1024\/0301-1526.35.2.67"],"URL":"https:\/\/doi.org\/10.1024\/0301-1526.35.2.67","relation":{},"ISSN":["0301-1526","1664-2872"],"issn-type":[{"value":"0301-1526","type":"print"},{"value":"1664-2872","type":"electronic"}],"subject":[],"published":{"date-parts":[[2006,5,1]]}}}
