ABSTRACT
SESSION TITLE Rare Cases with Masquerading Pulmonary Symptoms SESSION TYPE Rapid Fire Case Reports PRESENTED ON 10/18/2022 0135 pm - 0235 pm INTRODUCTION:
Paget-Schroetter (PS) syndrome, also known as venous thoracic outlet syndrome, is a primary thromboembolic sequela of compression of the subclavian vein. CASE PRESENTATION A previously healthy 24 year old male presented with shortness of breath and cough. He had recently been exposed to COVID. He denied fever, diarrhea, vomiting, leg swelling, and rashes. On physical exam he was tachycardic, had no murmurs or JVD, and was CTAB with no wheezing or rales. Labs were significant for a WBC of 17k, and troponin of 0.033. CTA of the chest showed multiple filling defects in the pulmonary arteries consistent with Pulmonary Embolism (PE). He was started on a heparin drip. All COVID testing was negative. Lower extremity venous doppler ultrasounds (US) were negative for DVT. His respiratory status improved, and he was discharged on apixaban with the diagnosis of PE provoked by possible COVID infection. He returned approximately 2 months later with exertional dyspnea and upper extremity swelling and was found to have recurrent PE despite having been compliant with his apixaban. Upper extremity venous doppler US was significant for DVT in his right subclavian vein. He was placed on warfarin. At this time his hypercoagulable workup was also negative. Symptoms persisted despite being on warfarin with outpatient monitored INR. A venogram was ordered to evaluate upper torso blood flow. The venogram was remarkable for high-grade stenosis of the right subclavian vein. This finding led to the consideration of thoracic outlet syndrome aka Paget-Schroetter (PS).DISCUSSION:
PS is a rare clinical entity that results from stress placed on the endothelium of the subclavian vein as it passes between the junction of the first rib and the clavicle. It can predispose otherwise healthy patients to recurrent venous thromboembolisms that are refractory to anticoagulation. The clinical features usually include upper extremity swelling and pain which is exacerbated by repetitive or strenuous exercise. Venous collaterals can also be seen in some patients. Evaluation should include some form of upper extremity Doppler and a CT/MR venogram or venography to make the final diagnosis. Treatment may involve anticoagulation, thrombolysis, and/or surgical decompression. Best results are seen with early thrombolysis and surgical decompression. If caught early and treated appropriately, PS has a good outcome with few long-term sequela.CONCLUSIONS:
Our goal was to describe a patient with an uncommon cause for recurrent venous thromboembolisms that were refractory to anticoagulation. Our patient's presentation of PS serves to describe many aspects of the disease process, evaluation, diagnosis, and management as seen in the case presentation. The patient's demographic fit the epidemiological profile age of 20s-30s with typical imaging findings and pertinent negative workup which would lead providers to this rarer diagnosis.
