Acute pulmonary embolism (PE) is commonly associated with trauma-related orthopedic procedures (63% or even higher). Massive PE in this setting requires meticulous treatment decisions to reduce bleeding risk. We hereby present such a case where we successfully used a combination of fibrinolysis and catheter-directed fragmentation and multidisciplinary approach for intraoperative massive PE.

| Introduction|| |
Pulmonary embolism (PE) during the perioperative period is fairly common, especially in the traumatic orthopedic injuries (63% clinical and even higher subclinical.) Massive PE has a very high mortality rate, which exceeds 50%. Hence, prompt diagnosis and management are of utmost importance in such cases. The management strategy in the perioperative period for massive PE should be based on the risk and benefit of each procedure (i.e., fibrinolysis, mechanical thrombolysis/thrombus fragmentation, etc.,). We present a case of intraoperative massive PE in a traumatic femoral shaft fracture fixation procedure which was managed by a multidisciplinary approach.
| Case Report|| |
A 52-year-old female, without any prior atherosclerotic risk factors, presented to the orthopedic department with a history of trauma to the leg during a road traffic accident around 10 days back. She was referred from an outside hospital for corrective surgery. She was evaluated and counseled for spinal and general anesthesia (if required). She was in the American Society of Anesthesiologists Grade II with normal blood investigations and electrocardiogram (ECG). After appropriate fasting period and written informed consent, she was taken up for open reduction and internal fixation with nailing/plating of fracture shaft of the femur.
A few minutes into the procedure, there was a sudden fall in oxygen saturation from 98% to 40% on room air, with a lowering of consciousness. The patient developed hypotension. Cardiopulmonary resuscitation was then started. Injection adrenaline was given intravenously. The airway secured with 7-mm endotracheal tube. Surgery was stopped with an open leg wound. Oxygen saturation was at 30% even with 100% FiO2(with positive end-expiratory pressure of 6 cm H2O and ETCO2 of 26 mm Hg). On auscultation, she was found to have preserved air entry without any adventitial sounds. Hence, acute massive PE was suspected. Arterial blood gas evaluation showed mixed acidosis (pH of 7.1). ECG [Figure 1]a showed sinus tachycardia at the rate of 150 bpm, rightward axis (120°) with limb leads showing right ventricular strain pattern and S1Q3T3 sign. Intraoperative transthoracic echocardiogram [Figure 1]b revealed dilated right atrium and right ventricle (RV), dilated main pulmonary artery with filling defect, D-shaped interventricular septum in both systole and diastole with preserved left ventricular function. RV systolic dysfunction was noted [tricuspid annular plane systolic excursion (TAPSE) = 9mm]. Pulmonary artery systolic pressure (PASP) was 30 mm Hg.
The surgery was then stopped with an open leg wound which was packed to prevent blood loss. The supportive management with fluid resuscitation was started. The patient was given bolus intravenous heparin (5000 IU) and started on fibrinolysis with alteplase (10 mg bolus followed by infusion of 90 mg over 2 h). After hemodynamic stabilization, she was shifted to the catheterization laboratory for pulmonary angiography.
On invasive evaluation, the main pulmonary artery was dilated with no filling defect. Left pulmonary artery and left-sided lobular arteries showed good peripheral filling [Figure 2]. The right-sided pulmonary artery was occluded at the division, and the upper lobar branch was not visible with poor peripheral filling [Figure 3]a. The right pulmonary artery was wired, and the catheter was tracked over it. Mechanical thrombus fragmentation was performed. After mechanical fragmentation also there was significant residual thrombus in the right pulmonary artery [Figure 3]b. The patient was kept on anticoagulation with heparin. The patient developed bleeding postfibrinolysis and required three packed red cell transfusions due to a significant fall in hemoglobin.

Bilateral lower limb doppler done on day 4 postprocedure showed thrombotic occlusion of the left tibial-peroneal trunk and posterior tibial vein. Multiple detector computed tomography (CT) done on day 4 postprocedure showed a partial filling defect in bilateral pulmonary arteries. Inferior vena cava (IVC) filter [Figure 4]a was put electively on day 8 postprocedure, and the patient was taken up for the treatment of fracture shaft of the femur. The procedure was completed under combinedspinalepiduralanesthesia without any complications. IVC filter was kept for a whole year and CT chest was done. It was found to be free of thrombus. The IVC filter was then removed [Figure 4]b. Echocardiogram repeated at the time of discharge revealed recovered RV systolic function with PASP of 25 mmHg.
She was kept on anticoagulation till 6 months after IVC filter removal. She is completely asymptomatic off oral anticoagulation after follow-up of around 28 months.
| Discussion|| |
Surgery increases the risk of PE almost five times, making it to be a major life-threatening complication. Orthopedic surgical procedures have an incidence of PE ranging from 0.7%–30% in different case series. Fat embolism is a common cause of PE during orthopedic surgery, especially during the treatment of long bone fractures. The mortality in an untreated massive PE can be as high as 70%. Hence, prompt initiation of treatment is of paramount importance.
Treatment of PE in a perioperative setting requires a multidisciplinary approach with a team consisting of a cardiologist, anesthetist, and operating surgeon, etc., The risk of bleeding has to be weighed against the benefit of the treatment strategy to be undertaken. Various treatment modalities such as systemic fibrinolysis, catheter-directed fibrinolysis, catheter-directed thrombectomy, or surgical embolectomy are available. Massive PE with hemodynamic stability and right ventricular dysfunction may be treated with low mortality by surgical embolectomy. As the patient was hemodynamically stable and bleeding could have been controlled while still on the operating table, the option of anticoagulation with fibrinolysis was attempted.
A pulmonary angiogram is the gold standard for the diagnosis of PE, but an early diagnosis can be made with ECG and bedside echocardiogram (as was done in our case) before deciding on the management. Mohan et al. studied the use of catheter-directed fragmentation (CDF) in the treatment of acute high-risk PE to find that rapid reperfusion of pulmonary arteries with mechanical fragmentation followed by intrapulmonary thrombolysis results in excellent immediate and intermediate-term outcomes. We have also used a combination of fibrinolysis with CDF for the treatment with a good outcome.
There was a 4% incidence of major bleeding requiring transfusion in the study done in 2014. Similarly, in our case, there was increased bleeding, which required blood transfusion.
In conclusion, the treatment of perioperative PE is an emergency and requires a team approach. A combination of fibrinolysis with CDF is feasible and safe in such a situation, but it may entail an increased risk of bleeding.
