Veins of the Abdomen and Pelvis01:18

Veins of the Abdomen and Pelvis

The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

  • Umbilical venous catheters (UVCs) are critical for treating critically ill neonates in the NICU.
  • Improper UVC positioning is associated with a significant risk of major adverse events.
  • Current methods for confirming UVC tip position, primarily X-rays, have limitations.
