“…to re-open the umbilical vein. In fact, more than 75% of umbilical veins can be used for re-catheterization (8). Numerous studies have been conducted regarding umbilical vein catheterization, but we did not find a similar study that demonstrates the association between neonatal age and success rate of umbilical vein cut down.…”

Background: Umbilical vein cutdown in neonates as an important method of accessing vascular is very important in cases in which peripheral vein is not available and it is not possible to cut down another vein. The umbilical vein is believed to become thrombotic and lumen is closed and unusable one week postpartum. Methods: In this cross-sectional study, all neonates who were admitted to the surgical ward of Mohammad Kermanshahi Hospital in Kermanshah, who needed emergency vein access and who were unable to have vein cutdown elsewhere during 2012-2014 were enrolled. The participants were divided to four age groups (one week to four weeks) and the possibility of umbilical vein cutdown was assessed in each group. Results: Of all participants, 25 infants were girls and 20 were boys. The umbilical vein cutdown was successful in 39 patients (86.7%), and failed in 6 patients (13.3%). The procedure was successful in all infants younger than 3 weeks old except for one case, while the success rate rapidly decreased after 3 weeks old. Conclusions: Umbilical vein cutdown was successful in infants under three weeks old and it was not possible afterward due to umbilical vein thrombosis. One-week age restriction for umbilical vein cutdown is questionable and requires further randomized trials with a control group to reach definitive conclusions.

“…A total of 53 perfusate fractions originating from seven different monkeys were assayed, (b) In vivo: Eight monkeys (three of these having implanted hypothalamic cannulas) were anesthesized with Ketamine HC1, and cannulas were placed in the portal vein and the femoral vein. The portal vein was cannulated by the technique of Malt et al 19 By a small midline supraumbilical incision the cannula was passed through the round ligament (the collapsed umbilical vein) that connects with the left branch of the portal vein. Immediately after cannulation and for five minutes prior to the injection of the hypothalamic perfusate, two baseline samples were obtained ( -5 minutes and 0).…”

Hypothalamic Regulation of Insulin Release in Rhesus Monkeys

et al. 1977

Evidence of a neurohumoral factor capable of stimulating insulin and glucagon secretion was found in perfusates from ventrolateral hypothalamus (VLH) of rhesus monkeys. The perfusates from the VLH were collected via push-pull cannulas and injected into the peripheral circulation. Increase in portal insulin and glucagon was observed following the injection of six different perfusates. The amount of insulin released from isolated rat islets incubated with perfusates was significantly increased at glucose concentrations greater than 5 mM. The perfusates from the VLH appear to have effects on insulin and glucagon secretion that are opposite those of somatostatin.
