What is a contraindication for CVAD placement?

• A. Diabetes mellitus
• B. Coagulopathy or severe bleeding disorders
• C. Obesity
• D. History of infections

Answer: (B)

When considering contraindications for central venous access device (CVAD) placement, coagulopathy or severe bleeding disorders is a pivotal concern. The fundamental reason lies in the increased risk of bleeding during and after the procedure. This risk can lead to significant complications, such as hematoma formation, prolonged bleeding, and potentially severe consequences if the device is placed in an area where vessel damage occurs.

In contrast, conditions such as diabetes mellitus, obesity, and a history of infections, while they may pose challenges or require special considerations during the placement or management of CVADs, do not outright prevent the procedure. Diabetic patients, for example, can successfully receive CVADs with careful monitoring of blood sugar levels and wound care. Similarly, patients with obesity may require adjustments to the technique but can still have a CVAD placed. Lastly, a history of infections might necessitate extra precautions or screening, but it does not inherently disqualify someone from receiving a CVAD. Thus, coagulopathy stands out as the most definitive contraindication due to its direct impact on procedural safety.
