Context: 46 year old woman with no relevant medical history or active medication except oral contraceptives, which came to our primary care clinic with symptoms of a few hours of itching, pain and oedema in left lower limb.
Methods:  Examining the patient: good overall condition, mild pale skin and mucous membranes, haemodynamically stable.
Lower limbs swollen of the entire left lower extremity, hard, pasted, positive Homan's sign. Wells Score: 4.
Having a high suspicion of DVT, we derive the patient to the emergency room for evaluation and complementary studies as may be lower limb Doppler ultrasound and laboratory tests.
Results: In the emergency room the following examinations and additional tests were performed.
analytical Values ​​of note:
D-dimer: negative (Ekg: Sinus rhythm at 80 beats per minute, with no signs of ischaemia or hypertrophy.
Conventional X-ray chest film: unchanged.
Even with negative D Dimer, guided by a very suggestive physical examination (Wells Criteria> 3), it was decided to ask Eco colour Doppler lower limb, which resulted in a deep vein thrombosis in the left popliteal vein.
As oral contraceptive treatment was suspended and added 120 mg subcutaneous enoxaparin daily to meet in haematology.
Conclusions: It is important to consider that negative D dimer not always excludes deep venous thrombosis because what is really vital to any doctor, either in primary care or not, is the clinic patient.
