Case Report DVT/PE Brenda Mertsock, PA-S Lock Haven University September 2008 Presenting Symptoms This is what we saw! Patient drove herself to the ER CC: Shortness of Breath Tightness in her chest X a few hours. VS: 148/95, 82, 20, 98.2 F HPI: Included rt. leg was swollen, warm to touch, and painful X 12 days. Pain was now a 3 out of 10, but it felt like a cutting, tight rope pressure behind the knee that was much more swollen and tender for the past 12 days. HPI Aug, 1st, active doing yard work, felt pain behind the knee Aug, 2nd, hauling logs, trimming trees, more physical activity, - swollen rt knee Aug 3rd, knee so swollen, she reclined most of the day with it elevated, also noticed an exacerbation of low back pain Aug 4th, her usual chiropractor out of town, went to someone new, showed him her leg and he agreed it was swollen and worked on her back Aug 6th, her chiropractor back in town, he attributed her swollen leg to her back pain Aug 7th, went to her primary care physician, he said her SI joint was out and that there was probably some pooling from that. No one ever made a measurement. By this time, she felt like her skin could not stretch anymore, she elevated it every night, but nothing helped. She continued to walk daily, work in her very busy professional business, and do household chores. Aug 9th, her and her husband drove to North Carolina and then on Monday drove 10 hours back. On Tuesday the 12th, she went to work and that evening was in the ER with SOB. Tests Ordered & PE Right lower leg moderate to severe tenderness, CBC, BMP, D-Dimer, PT, PTT, cardiac swelling, and warmth to the post rt. knee, calf, enzymes, EKG, venous duplex of right lower and rt. popliteal. extremity, and a CT chest with IV contrast. PE: no increased JVD or thyromegaly, lungs were CTA Bilat., RRR, S1 and S2 with no murmurs, + abd BS, soft, NT, no oganomegaly, no guarding or rigidity, portable chest x-ray was unremarkable. Lungs were well expanded, unremarkable heart, hila, and mediastinum. Tenderness to a cord-like structure along the great saphenous vein post. to the knee medially along the thigh. Recent Past Medical History Past 6 mo. new onset of hypothyroidismtaking 25mg daily of Levothyroxine Past 6 mo. New onset of menorrhagiataking Solia .15/.03mg Past mo. skin rash- taking 5 mg prednisone Takes multivitamin and Oyster-D Allergic to Penicillin Differential Diagnosis DVT Acute deep vein thrombosis of the right leg popliteal vein, great saphenous vein thrombosis- underlying etiology of Oral contraceptives Chest pain ruling out PE or MI Hypothyroidism Test Results Pertinent lab results: White ct – 12,700 Neutrophils- 90.4% Negative cardiac enzymes D-dimer- over 5000 ug/ml (0-300 ref range) Venous Doppler showed rt common femoral and femoral veins patent, Rt popliteal vein was occluded and contained thrombus with minimal flow, posterior tibial vein appeared to be patent. CT showed extensive pulmonary emboli through-out the pulmonary arteries bilaterally. This was so extensive there were only a few branches that were not involved. Treatment Admit to hospital with BRP only… For 6 days Sub-Q Lovenox 100 mg/ml q 12 hr Use until therapeutic oral anticoagulation of Coumadin is established with a level between 2 and 3. Pt will be on anti-coagulant therapy for 9 mo to a year and monitor PT-INR. Pt was informed of risks and benefits of treatment. Pt will continue on thyroid med, vitamins, and discontinue OCP. Why did it Happen? Ethinyl estradiol and norgestrel Brand Names: Cryselle 28 Patient had no previous history of any type Lo/Ovral- 28 Low-Ogestrel-28 Ogestrel-28 of thrombolytic event. Pt had no complications with previous oral contraceptive use. Pt had no contributory family history. New onset of hypothyroidism and contributing symptom of menorrhagia? Maybe. Reinstated use of Oral contracptives? Maybe. Oral Contraceptive Use Solia Equivalent to: Desogen Ortho-cept The pt. took Cryselle (2nd generation OCP) Apri Reclipsen from Feb to May, could not tolerate it. The pt. took Solia (3rd generation OCP) from May to Aug. 2nd an 3rd generation OCPs contain different levels of progestin. 2nd- Norgestrel 3rd- Desogestrel What Happens? Desogestrel causes resistance to activated protein C (APC) Decreases total and free protein S Causes more pronounced APC resistance. When APC and protein S cannot perform their natural function of inhibiting coagulation, clots tend to form more easily. Increasing the risk of venous thrombosis. If a pre-existing pro-thrombotic condition exists, the risk increases 35-fold What Happens -600,000 episodes of PE in the US annually -100,000 – 200,000 deaths -Most not suspected or unrecognized -Common cause of death a week to ten days after a thrombosis formed. -Proximal lower extremity venous thrombosis has been reported to be the source of 90% of emboli. -Symptoms of a PE could include; chest pain, dyspnea, hemoptysis, JVD, fever, tricuspid regurgitation, increased pulmonic heart tone, tachycardia, tachypnea, and pleural effusion. . Clinical Risk Factors for DVT/PE Age greater than 40 Previous DVT/PE Surgery requiring anesthesia for more than 30 min. Prolonged immobilization Stroke Heart failure Malignancy Fractures of long bones or pelvis Spinal cord injury Obesity Smoking Pregnancy - Renal failure - Nephrotic syndrome - Central venous catherization - COPD - Long distance travel - Genetic or acquired thrombophilia -Inflammatory bowel disease - Estsrogen therapy Discussion At this time there is a petition to the US Food and Drug Administration to ban third generation oral contraceptives containing desogestrel. There have been documented case of women of all ages experiencing DVTs from taking OCPs that contain desogestrel. Pro-thrombotic blood tests are not routinely checked, so prior knowledge is often unknown to the patient. Need to consider history, physical, and risks, when prescribing OCPs.
