The pancreaticoduodenal arteries in human foetal development
Folia Morphol 2004;63(3):281-284.
Abstract
Knowledge of the course of the pancreaticoduodenal arteries is of great importance
in pancreatic surgery. Lack of care in the preparation of these vessels may
lead to ischaemia or necrosis of the duodenum, the first loop of the jejunum,
the head of the pancreas and even the liver, bile ducts and transverse colon. In
such events, the surgeon would need to diagnose the course of the vessels and
their anastomoses intraoperatively. Anatomical dissection in this special area
diminishes the risk of early complications in the form of bleeding and late complications
in the form of narrowing of the anastomoses, fistulas, necrosis and
intestinal ileus after surgical resection or drainage. The aim of the present study
was to determine the variability of the pancreaticoduodenal arteries in human
foetuses. The material examined consisted of 60 human foetuses of both sexes
(33 male, 27 female) from spontaneous abortion or stillbirth and ranging in age
from the 16th to 38th week of prenatal life. White latex solution to of volume
between 15 ml and 30 ml was injected into the thoracic aorta. The results of this
were that a typical pancreatic supply from the coeliac trunk and superior mesenteric
artery was observed in all cases. The coeliac trunk, splenic artery and gastroduodenal
artery also appeared invariably. However, variability was observed
in further generations of branches. The gastroduodenal artery with its branches,
the anterior and posterior pancreaticoduodenal arteries, was constantly present.
Irrespective of the sex of the foetus, in 10% of cases a large vessel was observed
which ran horizontally on the anterior surface of the pancreas from head to tail
and which originated in the anterior superior pancreaticoduodenal artery. We
termed this vessel the "anterior pancreatic artery". In all cases there were anterior
and posterior pancreaticoduodenal arcades, but in two cases (3.3%) a double
anterior pancreaticoduodenal arcade was observed.
