Quick answer
How should I present a deep vein thrombosis case on rounds?
Open with the unilateral calf swelling and the recent long-haul flight, since that immobility is the precipitating risk factor. Give the exam findings and the ultrasound result confirming thrombus before naming DVT as the diagnosis. End with starting anticoagulation, checking respiratory symptoms for possible pulmonary embolism, and what still needs confirming, like renal function.
Before you speak
Define the moment and the information you actually have
An urgent-care presentation immediately after the compression ultrasound result returns.
A supervising physician deciding on anticoagulation and whether to evaluate for pulmonary embolism.
History, medications, social history, exam findings, and a compression ultrasound. A formal Wells score and renal function panel are not itemized.
About 70 seconds
Fictional training case: The presentation is locked to the simulated patient JSON. It names important unknowns instead of inventing an examination, vital signs, allergies, or tests.
Complete spoken example
First, read it once without stopping
The paragraph breaks show the clinical shape. In a real presentation, pause briefly between ideas rather than announcing the headings.
Mr. Shin is a 62-year-old man with hypertension who presents with three days of throbbing pain, swelling, and redness in his left calf, one week after a 12-hour international flight.
His left calf measures 4 centimeters larger in circumference than the right. He initially thought he had pulled a muscle or was cramping, but he is now worried the clot could travel to his lungs.
He has hypertension, treated with lisinopril, and is retired and does not smoke.
On exam, the calf is warm, red, and tender along the deep venous course, with no respiratory distress. Compression ultrasound shows a noncompressible thrombus extending from the popliteal vein into the distal femoral vein with absent color flow.
My diagnosis is proximal deep vein thrombosis of the left leg, extending from the popliteal into the femoral vein, most likely provoked by prolonged immobility during his recent flight.
I would start therapeutic anticoagulation now that ultrasound has confirmed the diagnosis, after assessing bleeding risk and renal function, and would ask specifically about chest pain or shortness of breath to screen for pulmonary embolism. I would counsel him on anticoagulation and clear return precautions.
Build the presentation
Give every sentence one job
A presentation is a compressed clinical argument, not a chart read aloud. These six moves keep the facts connected to your reasoning.
Opening one-liner
Name the unilateral swelling and its trigger
“Mr. Shin is a 62-year-old man with hypertension who presents with three days of throbbing pain, swelling, and redness in his left calf, one week after a 12-hour international flight.”
Why it belongs: Naming the unilateral calf findings and the specific immobility trigger together tells the listener why DVT is the leading concern before any test result is given.
This is a 62-year-old with a swollen leg.
Mr. Shin has three days of unilateral calf pain and swelling, one week after a 12-hour flight.
Why: Specifying that the swelling is unilateral and naming the immobility trigger carries more diagnostic weight than a general description.
History of present illness
Give the measured size difference and his own theory
“His left calf measures 4 centimeters larger in circumference than the right. He initially thought he had pulled a muscle or was cramping, but he is now worried the clot could travel to his lungs.”
Why it belongs: A measured circumference difference is more objective than 'swollen,' and naming his own concern about pulmonary embolism is a natural bridge to why this diagnosis matters beyond the leg itself.
His leg looks bigger than the other one.
His left calf measures 4 centimeters larger in circumference than the right.
Why: A measured value is more useful to the listener than a subjective description.
Relevant background
Give risk factors and current medications
“He has hypertension, treated with lisinopril, and is retired and does not smoke.”
Why it belongs: This confirms there is no other major competing risk factor or medication interaction to account for before starting anticoagulation.
He's on a blood-pressure pill.
He has hypertension treated with lisinopril, with no other major risk factors identified.
Why: Stating that no other major risk factor was found is more informative than listing medications alone.
Objective data
State the exam and the confirmatory ultrasound
“On exam, the calf is warm, red, and tender along the deep venous course, with no respiratory distress. Compression ultrasound shows a noncompressible thrombus extending from the popliteal vein into the distal femoral vein with absent color flow.”
Why it belongs: The absence of respiratory distress is a relevant negative for pulmonary embolism, and the ultrasound gives the exact anatomic extent of the clot, which affects both risk stratification and anticoagulation planning.
The ultrasound showed a clot.
Ultrasound shows a noncompressible thrombus extending from the popliteal into the distal femoral vein.
Why: Naming the exact veins involved is more clinically useful than saying only that a clot was found.
Assessment
Commit to the diagnosis and its anatomic extent
“My diagnosis is proximal deep vein thrombosis of the left leg, extending from the popliteal into the femoral vein, most likely provoked by prolonged immobility during his recent flight.”
Why it belongs: Naming this as proximal, not just 'a DVT,' matters because proximal clots carry a higher risk of embolizing to the lungs than isolated distal clots.
He has a blood clot in his leg.
This is a proximal deep vein thrombosis extending from the popliteal into the femoral vein.
Why: Naming the proximal extent signals higher embolic risk than a distal clot alone.
Plan
Start anticoagulation and screen for pulmonary embolism
“I would start therapeutic anticoagulation now that ultrasound has confirmed the diagnosis, after assessing bleeding risk and renal function, and would ask specifically about chest pain or shortness of breath to screen for pulmonary embolism. I would counsel him on anticoagulation and clear return precautions.”
Why it belongs: Anticoagulation should follow, not precede, confirmation of bleeding risk and renal function, and actively screening for respiratory symptoms addresses the reason this diagnosis is dangerous in the first place.
I'll put him on blood thinners.
I would start anticoagulation after confirming bleeding risk and renal function, and screen for respiratory symptoms of pulmonary embolism.
Why: Naming the safety checks and the PE screen shows a more complete plan than stating the medication alone.
Do not fill the blanks
Say what has not yet been established
Real presentations often happen before the chart is complete. A brief, explicit limitation is safer and more credible than a polished invention.
Renal function and bleeding-risk assessment
Say: “Renal function and a formal bleeding-risk assessment are not documented in this simulation and are needed before finalizing the anticoagulant choice and dose.”
Anticoagulant selection and dosing depend on kidney function and bleeding risk, not on ultrasound findings alone.
Respiratory symptoms and vital signs
Say: “Vital signs and oxygen saturation are not part of this simulation, and I would check them directly to screen for a coexisting pulmonary embolism.”
A patient can have a significant PE without obvious respiratory distress on a brief encounter.
Clinical compression
What leads, what stays, and what can wait?
| Source detail | Decision | Reason |
|---|---|---|
| Unilateral calf pain, swelling, and redness after a long-haul flight | Lead | This is the core presentation and its precipitating risk factor. |
| Left calf 4 centimeters larger than the right | Include | A measured difference is more objective evidence than a subjective description of swelling. |
| Retired, non-smoker | Compress | Brief background that does not change the immediate diagnostic or treatment decision. |
| No respiratory distress on exam | Include | This relevant negative is worth stating explicitly given the concern for pulmonary embolism. |
| Ultrasound showing thrombus from the popliteal to the femoral vein | Lead | This is the definitive diagnostic finding and shapes the risk discussion. |
After the presentation
Likely attending questions
Answer the question first, then give the evidence. If the source case does not contain the answer, say what you would verify.
Why does it matter that this is a proximal clot?
Proximal DVT, involving the popliteal vein or above, carries a substantially higher risk of pulmonary embolism than an isolated distal calf-vein thrombosis, which affects both the urgency of anticoagulation and the intensity of monitoring for respiratory symptoms.
Should you order a D-dimer now that ultrasound is positive?
No, a D-dimer adds no value once ultrasound has already confirmed the diagnosis; it is useful earlier in a diagnostic pathway to help decide whether imaging is needed at all.
What would make you worry about a coexisting pulmonary embolism?
Chest pain, shortness of breath, or a low oxygen saturation would raise concern and prompt urgent evaluation for pulmonary embolism; none of these has been assessed yet in this simulation.
Self-check
A 30-second check before you present
- Name the unilateral swelling and its precipitating trigger together.
- Give a measured circumference difference, not just 'swollen.'
- State the exact veins involved on ultrasound.
- Name the clot as proximal or distal, since this changes risk.
- State that respiratory symptoms are being actively screened for.
- Confirm renal function and bleeding risk before finalizing anticoagulation.
- State the anticoagulation plan and counseling given.
- Note what vital signs or oxygen saturation still need checking.
Common presentation problems
Repair the habits that make a case hard to follow
Calling this simply 'a DVT' without stating its extent
Repair: State whether it is proximal or distal, since this changes the embolic risk.
Starting anticoagulation without checking renal function or bleeding risk
Repair: State that these are confirmed first.
Assuming no PE because the patient looks comfortable
Repair: State that respiratory symptoms and oxygen saturation are being actively checked.
Ordering a D-dimer after ultrasound already confirmed the clot
Repair: State that D-dimer is not useful once imaging has already made the diagnosis.
Frequently asked questions
Oral case presentation questions
Do I need to mention Homan's sign?
You can note that it was not relied upon, since it is an unreliable exam finding; ultrasound is the diagnostic test that matters here.
Should I discuss outpatient versus inpatient anticoagulation?
Yes, briefly, if your setting allows outpatient management for hemodynamically stable DVT without evidence of PE; the decision depends on local protocol and his overall stability, which should be confirmed first.
How long should this presentation be?
This worked example targets about 70 seconds. A patient with respiratory symptoms suggesting PE would need a longer, more urgent presentation.
