What is a contraindication for venous port placement?

Severe coagulopathy is indeed a contraindication for venous port placement due to the increased risk of bleeding and complications during and after the procedure. Coagulopathy refers to a condition where the blood's ability to clot is impaired, potentially leading to excessive bleeding or hematoma formation when a vascular access device, such as a venous port, is inserted into a blood vessel. Given that the insertion of a port requires puncturing a vein, this impaired clotting can create significant risks for the patient, making it critical to avoid such procedures in individuals with severe coagulopathy.

In contrast, minor infections generally do not preclude the placement of a venous port, especially if the infection is localized and can be managed. Well-controlled diabetes does not usually pose a barrier to port placement either, as long as blood sugar levels are stable and the patient's overall health is not compromised. Similarly, hypertension, when well-managed, is not considered a contraindication, as the vascular system can usually tolerate the temporary stress of the procedure without significant risk.
