Assessment of the Abdomen III: Palpation01:23

Assessment of the Abdomen III: Palpation

5.6K
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...

Assessment of the Cardiovascular System III: Palpation

1.6K
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Technology

Background:

  • Calvarial lesions present diagnostic challenges due to their location near critical structures.
  • Traditional biopsies may involve significant radiation exposure and complex surgical approaches.

Observation:

  • An 86-year-old female with a left parietal lytic skull lesion underwent biopsy using Surgical Augmented Reality (AR).
  • The AR system provided hands-free, image-guided navigation, registering via fiducials and a QR code ground truth.

Findings:

  • The frameless AR navigation system facilitated precise localization and visualization of the calvarial lesion.
  • A successful biopsy was performed in 35 minutes with intraoperative pathology confirming metastatic carcinoma.
  • The AR system operated without obscuring the surgical field or requiring extensive setup.

Implications:

  • Augmented reality offers a promising, radiation-sparing alternative for complex calvarial lesion biopsies.
  • AR navigation can enhance accuracy and efficiency in neurosurgical procedures involving difficult-to-access lesions.
  • This technology may improve patient outcomes by reducing surgical risks and improving diagnostic yield.
