Congenital Anomalies of Arteries and Veins 27 



A. Hepatica 



This vessel shows more irregularities than any other of the 

 group. It may be double. Rossi found an accessory branch to 

 the left lobe 21 times in 102 bodies, and I have seen the same 

 number in 160 subjects and 12 cases in which the right branch was 

 double. Sussloff (1907) found the left branch present 17 times 

 and the right double 9 times in 131 subjects. Other cases of 

 aberrant arteries are reported by Walther (1729), Petsche (1736), 

 Haller (1746), Rudolph (1781), Barkow (1868), Dupis (1874), 

 Jacqu'emet (1894), Guibe (1901), Gentes (1906), Branco (1912), 

 Budde (1906), Lipschutz (1917). 



The condition of three hepatic arteries is a rarer condition. I 

 have encountered it only once, in which case a branch to the right 

 lobe and one to the left arose from the coeliac, while a second 

 branch to the gall bladder came from the superior mesenteric. 

 Other cases are reported by Tiedemann (1822), Meckel (1825), 

 Green (1830), Lauth (1833), Labatt (1837), Dubrueil (1847), 

 Barkow (1868), Rolleston (1889), Franz (1896), Brewer (1903), 

 Budde (1906), Gerard (1914). 



Four vessels have been recorded by Lauth (1833), Cruveilhier 

 (1841), Rossi (1904), Budde (1906). 



The hepatic ma:y arise from the superior mesenteric, a condition 

 which is very interesting morphologically, but which is readily 

 accounted for developmentally. See cases as follows : Mayer 

 (1783), Quain (1844), Barkow (1868), Davies (1873), Farabeuf 

 (1885), Hochstetter (1886), Struthers (1892), Tandler (1904), 

 Rossi (1904), Hecht (1905), Leriche (1907), Sussloff (1907), 

 Gentes (1907), Piquand (1909). 



The hepatic may arise normally from the coeliac, or the aorta 

 and an accessory artery may spring from the superior mesenteric, 

 or an anastomosing trunk between the two.
