A 65 yo male presented with 2 week hx of proximal left LE pain. Pt denied trauma or risk factors for VTE. Also did not have visible abnormalities on clinical exam. Seen here is POCUS of his common femoral vein; note the hyperechoic thrombus and absent blood flow (when compared to adjacent femoral artery). This vein was also non compressible. This case highlights that even with low pre-test probability, POCUS can help drive ones differential diagnosis!

A patient presented reporting a tender, erythematous, and edematous portion of his left forearm; notably at the site of an IV that had been in place at the time of a recent surgery. POCUS as seen here revealed a hyperechoic area within a vessel concerning for thrombus, consistent with the diagnosis of superficial thrombophlebitis. Point of care ultrasound can be useful in differentiating thrombophlebitis from other differential diagnoses including muscle strain or sprain.

69-year-old male patient with no relevant chronic medical history presents to the ER complaining of two-day right inguinal pain and swollen lower extremity. Directed interrogation revealed one-month subacute dyspnea upon physical effort.

Femoral POCUS showed this image. The contractile femoral artery lies superficially and to the left of the screen. The common femoral vein is not fully compressible in this study, and an echogenic thrombus can clearly be identified in its interior. Subsequently, angio CT confirmed a massive bilateral PE, although the patient remained stable and did not require invasive interventions.

The IVC drains into the RA. A normal IVC frequently demonstrates transmitted pulsations from the RA. This clip is taken over the subxiphoid region, longitudinally to the body’s axis, and with the probe marker oriented to the patient’s head and RA. The hepatic vein can also be seen draining into the IVC.

A 45-year-old female presented to the ED with chest pain, dyspnea, and evidence of shock. Our FOCUS cardiac exam was notable for acute pulmonary hypertension. Subsequently using our multi-organ approach we identified evidence of a DVT (linear probe on the proximal left leg reveals hyperechoic material within the non-compressible femoral vein). Diagnosis of pulmonary thromboembolism secondary to VTE causing obstructive shock was immediately confirmed at the bedside.

Patient with profound rapid onset lower extremity pain and swelling. POCUS can be used to rapidly assess for DVT with as high as 95% sensitivity and 96% specificity amongst ED providers. 

In this image the artery can be seen as the pulsating thick walled vessel with strong pulsations under color doppler. The vein is the large vessel with echogenic material with flow only around the edge of the clot. Inability to compress the vessel would confirm the diagnosis of DVT (not pictured).

Dr. Justin Bowra et al.

When pressure is applied to the ultrasound probe over blood vessels, veins usually collapse before arteries because of their much thinner walls. In this clip, enough pressure was applied to the ultrasound probe to partially collapse the popliteal artery, which is the pulsatile vessel visualized. Despite such high pressure, the popliteal vein remains fully patent, indicating a deep vein thrombosis within its walls.

Sukh Singh, MD

Patient with pain and swelling of the entire left lower extremity. Three point POCUS carries a sensitivity of 95% and specificity of 96% for detecting DVT when performed by emergency physicians. 

Mild external rotation of the hip can help open up the inguinal crease to find the femoral vein. The POCUS should be performed 1-2cm distal to the bifurcation of the common femoral for a complete study.

Axillary vein thrombus ruled OUT in a patient with arm swelling. Doppler used to highlight vein and artery.

Dr. Gordon Johnson

Patient with pain and swelling to area above the antecubital fossa where an IV had been the week before, a palpable cord was appreciated proximal to the former IV site. 

POCUS demonstrated a clot, likely septic thrombophlebitis secondary to IV site infection. This is a similar techinque as what is done for DVT by finding the vessel, looking for a clot, and seeing if the vessel can be compressed. 

Dr. Bowra et al. (Dr. Chiang)

Patient presented with near syncope and unilateral neck pain. Ipsilateral neck ultrasound revealed swirling blood within the IJ; subsequent evaluations identified etiology to be a thoracic aortic dissection contributing to pericardial effusion and cardiac tamponade!

A 27-year-old women presented to ED with acute onset of dyspnea and chest pain. She was hypoxic with an O2 saturation of 91% on room air and tachycardic. POCUS lung ultrasound revealed an A-line pattern bilaterally and was notably absent for pleural effusions. Venous scan of the proximal right femoral region revealed a non-compressible femoral vein with hypoechoic material within the lumen. High resolution chest CT confirmed diagnosis of PE.

When applying pressure to the ultrasound probe, veins collapse first while arteries remain patent and pulsatile. In this clip one can see that proximally, the large pulsatile vessel (which represents the common femoral artery) sits adjacent to a mostly compressible common femoral vein. As the probe moves distally and both the artery and vein split into deep and superficial branches, the superficial femoral vein is not entirely compressible along its medial aspect, representing a thrombus.

Sukh Singh, MD

The superficial femoral artery (pulsatile, to the left) and superficial femoral vein are visualized. As pressure is applied to the probe, the artery becomes oblong but the vein does not collapse as it should, indicated a deep vein thrombosis within its walls. Veins should collapse before arteries under pressure as they have much thinner walls.

Sukh Singh, MD

The greater saphenous vein, as it takes off from the femoral vein. Make sure to scan up this high and start compressions here to rule out DVT in the lower extremity.

Dr. Gordon Johnson

25yo w/ no PMH had left molar extracted 10days prior, presents with four days of subjective fever, malaise, and increasing pain to L neck, tachypneic and hypoxic and was intubated w/ central line placed.

POCUS scans through the jugular vein to reveal a clot. CT angiogram showed left internal jugular vein thrombosis, low attenuation L temporal lobe concerning for parenchymal abscess.

Active extravasation through endograft into false lumen. Known chronic endoleak, but CT 30 minutes prior to this study showed no active extravasation or impending rupture. Keep an open mind when reassessing your patients, and try not to anchor too much on prior results or others' opinions!

Dr. Elias Jaffa

The images above are from a middle-aged woman who presented to the emergency room as a stroke code. She complained of paresthesias in her right arm and had decreased sensation to
light touch. It was noted that this arm was colder than the left, so after she returned from head CT, POCUS was performed of her brachial artery.

There is a non-compressible hyperechoic structure inside the brachialartery, consistent with the clinical picture of an arterial embolus. Given the urgency of stroke treatment, these images were obtained after the stroke team had administered tenecteplase.

Vascular surgery consult was made aware of the findings and repeat images taken an hour after presentation and administration of tenecteplase were obtained at bedside with the vascular
surgery consult. These images show near resolution of the embolus.

This clip demonstrates compression of the popliteal vein moving distally from the popliteal fossa down the calf as is often done to assess for DVT. The non-compressible vessel deep and medial to the popliteal vein is the popliteal artery.

Hannah Kopinksi and Dr. Lindsay Davis - NYU Emergency Medicine

In this clip the color doppler helps to differentiate the popliteal artery (deep, red, pulsatile) from the popliteal vein (no color, superficial).
