'No DVT found' is not a diagnosis: look beyond the D-dimer

Area of Science:

• Medical Diagnostics
• Clinical Practice Research
• Vascular Medicine

Background:

• Current medical protocols may prioritize excluding serious conditions over diagnosing the root cause of patient symptoms.
• The diagnostic process for leg swelling often involves ruling out deep venous thrombosis (DVT).

Observation:

• A patient presented with leg pain and swelling, symptoms that can indicate DVT.
• Deep venous thrombosis was repeatedly excluded as a potential diagnosis during the patient's evaluation.
• The diagnostic pathway was influenced by established clinical practice guidelines.

Findings:

• The exclusion-focused approach led to a significant delay in identifying the actual cause of the patient's leg swelling.
• Protocol-driven practice, while intended for efficiency, can inadvertently hinder accurate and timely diagnosis.

Implications:

• Rethinking diagnostic strategies to balance exclusion of serious conditions with active pursuit of the underlying diagnosis is crucial.
• Clinical guidelines may need refinement to prevent diagnostic delays in cases like this.
• Improved diagnostic algorithms are needed to ensure prompt identification of the primary illness causing leg swelling.
