General Thermography

In most cases, the Right internal jugular vein drains the majority of warm blood flowing from the brain due to its connection with the superior sagittal sinus, while the left internal jugular drains the cooler facial regions.149 The large internal jugulars are, like the arteries, too deep to be detected thermographically; however, the thermally-visible external jugulars anastomose with and run parallel to the internal jugulars, carrying much the same blood (and heat) (Figure 10.47).150 The differential temperature of the right and left external jugular veins in healthy subjects may serve as an indicator of cerebral activity. More research is needed to clarify this finding.
Designing for Head and Neck Anatomy

The venous blood from the head flows back toward the heart through the four major veins of the neck, the R and L internal jugular veins and R and L external jugular veins (Figure 3.13). The veins lie adjacent to the carotid artery at the side and near the front of the neck.

A 77-year-old man with a history of systolic heart failure due to nonischemic cardiomyopathy. He was in NYHA Class III symptoms with multiple readmissions for acute systolic heart failure exacerbation. He was referred for placement of CardioMEMSTM PA sensor. Using ultrasound guidance and micropuncture technique, the internal jugular vein was accessed. A Swan-Ganz catheter was advanced and used to perform right heart catheterization and to perform selective left pulmonary arteriography. The CardioMEMSTM PA sensor device was advanced over the Command wire 0.018 into the left pulmonary artery. At that point, there was inability to advance the delivery catheter of the CardioMEMSTM device over the wire. The wire was then pulled back, but it was locked in the delivery catheter and would not advance nor pullback inside the delivery catheter. We then decided to retrieve the assembly including the wire, delivery catheter, and PA sensor. The wire was stuck and could not separate from the catheter itself. This particular device was discarded and was returned to the manufacturer for examination. A new CardioMEMSTM device and delivery catheter were then advanced over the wire to the target site and the CardioMEMSTM device was deployed at that location with no issues [Figure 3].
