DIC\u2010CT was used in 277 consecutive patients (135\u00a0men, 142 women) and for the dissection and histologic study of 10 cadaver livers. We found 32 subvesical ducts in 28 (10.1%) of 277 patients. Irrespective of whether the terminals were extra\u2010 or intraparenchymal, the subvesical ducts often (17\/32 ducts, 15\/28 patients) drained into a subsegmental duct of S5 or S4. Notably, some displayed an \u201cintermediate\u201d course along the gallbladder fossa with an intraparenchymal origin and terminated at S5. Such ducts tended to be seen in the elderly. Another 15 ducts drained into a thick, centrally located duct, such as the right sectorial or hepatic duct. The anatomic study demonstrated that the subvesical duct likely included the cystic vein\u2010concomitant duct. A major type of subvesical duct, characterized by an intermediate course along its bed, appeared to result from degenerative exposure of a peripheral duct with aging. The subvesical duct draining into the thick duct included both a \u201cdaughter branch,\u201d such as seen in the lung, and the so\u2010called anomaly. Such ducts can be demonstrated with DIC\u2010CT, but the incidence might be limited. However, the cystic vein\/concomitant duct was difficult to identify radiologically. Consequently, although presurgical radiology is useful for avoiding bile leakage after laparoscopic cholecystectomy, surgeons should be aware of its limitations.<\/jats:p>","DOI":"10.1007\/s00268-004-7652-5","type":"journal-article","created":{"date-parts":[[2005,1,13]],"date-time":"2005-01-13T08:51:31Z","timestamp":1105606291000},"page":"217-223","source":"Crossref","is-referenced-by-count":26,"title":["Heterogeneity of Subvesical Ducts or the Ducts of Luschka: A Study Using Drip\u2010infusion Cholangiography\u2010Computed Tomography in Patients and Cadaver Specimens"],"prefix":"10.1002","volume":"29","author":[{"given":"Masahiro","family":"Kitami","sequence":"first","affiliation":[{"name":"Department of Diagnostic Radiology Tohoku University Graduate School of Medicine 2\u20101 Seiryo\u2010cho 980\u20108574 Sendai Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gen","family":"Murakami","sequence":"additional","affiliation":[{"name":"Department of Anatomy Sapporo Medical University School of Medicine South 1, West 17 060\u20108556 Sapporo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daisuke","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Department of Anatomy Sapporo Medical University School of Medicine South 1, West 17 060\u20108556 Sapporo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kei","family":"Takase","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology Tohoku University Graduate School of Medicine 2\u20101 Seiryo\u2010cho 980\u20108574 Sendai Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahiro","family":"Tsuboi","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology Tohoku University Graduate School of Medicine 2\u20101 Seiryo\u2010cho 980\u20108574 Sendai Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haruo","family":"Saito","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology Tohoku University Graduate School of Medicine 2\u20101 Seiryo\u2010cho 980\u20108574 Sendai Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shoki","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology Tohoku University Graduate School of Medicine 2\u20101 Seiryo\u2010cho 980\u20108574 Sendai Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,1,6]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.1953.01260030616008"},{"key":"e_1_2_5_3_2","first-page":"447","article-title":"The developmental basis for bile duct anomalies","volume":"107","author":"Hayes MA","year":"1958","journal-title":"Surg.Gynecol.
