Intrahepatic bile duct and portal vein anatomy revisited

Seventeen normal cadaver livers were studied to assess the anatomic relationship of bile ducts to portal veins. The common bile duct, main portal vein, and hepatic artery were cannulated and injected with air, dilute contrast medium, and mineral oil, respectively. The livers were placed in anatomic position and examined with computed tomography. In the lateral segment of the left hepatic lobe, the bile ducts were anterior to the portal vein in seven cases, posterior in seven, and tortuous (ie, both anterior and posterior) in three. In the medial segment of the left lobe, the bile ducts were anterior in four cases, posterior in four, tortuous in three, and not seen in six. In the right lobe, the bile ducts were anterior in nine cases, posterior in five, tortuous in one, and not seen in two. In the porta hepatis, the bile ducts were anterior in ten cases, posterior in one, tortuous in five, and not seen in one. Histologic findings confirmed the anterior and posterior location of the bile ducts relative to the portal veins. These findings contradict the commonly held view of intrahepatic bile ducts being anterior to the portal vein and are clinically significant for techniques such as bile duct drainage.

Training Occupational Therapy Managers

There is a need for occupational therapists to become competent managers in a diverse range of health care settings. In this paper, the author's continuing education course on management which they have conducted at the West Australian Institute of Technology (now Curtin University of Technology) over the past four years. Details of participants, their reasons for attending and their comments on the course are included. The authors emphasise the need for more continuing education in management and the provision of skills for coping with organisational life, in particular in a female dominated profession such as occupational therapy.
