The authors report a case of bilateral pulmonary embolism (PE) with intermediate risk at the University Hospital center of Treichville (CHUT). This is a postpartum PE in a 37-year-old obese, multiparous woman with postpartum hemorrhage from uterine rupture after vaginal delivery initiated by injectable oxytocin. This postpartum haemorrhage was managed by massive transfusion and hysterectomy. The initiation of thromboprophylaxis was delayed in view of its coagulation record, the first 3 days. Later, the patient presented respiratory distress for which the completion of a pulmonary angioscanner made it possible to make the diagnosis of PE whose clinical evolution under heparinotherapy was favorable.


Pulmonary Embolism, Postpartum Hemorrhage, Disseminated Intravascular Coagulation, Thromboprophylaxis

1. Introduction

Pulmonary embolism (PE) is part of venous thromboembolism (VTE). It is a very common pathology whose current epidemiological data are estimated at more than 100,000 with annual incidence of 10 to 20,000 deaths per year in France [1] [2] [3] . In pregnant women, the risk of occurrence of PE is high. Physiological changes in haemostasis expose the pregnant woman to the risk of thromboembolic events [4] [5] [6] [7] [8] . In the case we report, this risk is increased by performing an obstetric surgery. The occurrence of postpartum hemorrhage complication associated with significant thrombocytopenia and a collapsed prothrombin level did not allow the practitioner to introduce effective postoperative thromboembolic prevention as early as possible.

2. Case Report

Mrs A.T. born on May 14, 1980, was admitted to the gynecology-obstetrics department of Treichville on September 6, 2017 for metrorrhagia on a pregnancy of 41 Weeks of Amenorrhea. In this department, an ultrasound found a grade III placenta normally inserted without image of detachment. It was decided to initiate a vaginal delivery with oxytocin. The delivery took place on the same day without epidural with expulsion of a female newborn weighing 3510 g with an Apgar score of 9 at one minute and 10 at five minutes. She received 10 IU oxytocin at the time of delivery with a tonic uterus, but bleeding persisted with postpartum haemorrhage having required uterine revision under general anesthesia. After this revision, an uterine rupture was diagnosed with hemorrhagic shock (blood pressure: 93/45 mmHg), and disseminated intravascular coagulation (DIVC). The preoperative assessment revealed a hemoglobin (Hg) rate of 6.8 g/dl (12 - 16.4), platelets with 74,000 elements (170 - 375 × 103), a TCA > 120 (26 - 40.4), a prothrombin rate at 15% (70% - 100%) and a fibrinogen 0.6 g/l (1.9 - 4.3). The patient underwent a transfusion of globular concentrate (17 bags) iso-rhesus iso-group and plasma (15 bags) before admission to the operating room. She was admitted to the operating room at H7 for hemostasis surgery where a total hysterectomy was performed. In immediate post operatory, the hemoglobin level was 13.5 g/dl and platelets were 38,000 elements. She did not receive preventive anticoagulation in view of her coagulation record. After discussion with the gynecologists, the anticoagulation started on third day (September 9, 2017) in the evening with first walk on the folowing day (September 10, 2017). The evolution during hospitalization in the obstetric gynecology department was marked by the appearance on fourth day (September 10, 2017) postoperative dyspnea in deep inspiration, with left basal thoracic pain and oxygen desaturation at 87%. The hemodynamic state was stable, the calves were soft and pulmonary auscultation was normal. The patient is put on oxygen therapy glasses at 3 l/min to obtain a SaO2 at 98%. A cardiological opinion was requested as well as additional examinations, and the patient was transferred to the intensive care unit of the University Hospital Center of Treichville.

3. History

We note an asthma, an osteosynthesis for a fracture of the tibia and fibula and an appendicectomy operated for more than 5 years, in this Obese patient (BMI at 32.2 kg/m2).

G9 P8 with 6 vaginal deliveries and a caesarean delivery, the 4th for fetal heart rate abnormality. She is also allergic to amoxicillin-clavulanic acid. We did not note any personal or family pulmonary embolism.

4. Physical Examination

The cardiological physical examination shows a haemodynamic stability with blood pressure (BP) at 130/80 mmHg, a eupneic patient at rest, without chest pain with free lungs. The sounds of the heart were regular without breathing, absence of left and right ventricular failure. The abdomen is supple and depressible, painless, marked by a high parietal adiposity impeding deep palpation. The neurological examination notes the absence of sensitivomotor deficit. In addition, the bandage of the surgical wound was clean.

5. Paraclinical Examination

Chest CT angiography performed on September 10 revealed a massive bilateral pulmonary embolism, involving the right and left proximal pulmonary arteries, with left-sided pleurisy (Figure 1). We note, moreover, a thrombus on a right proximal branch (box 1), and no impact on the pulmonary parenchyma (Figure 2). The ECG showed steady sinus rhythm at 75 bpm, normal repolarization, and absence of atrioventricular and intraventricular conduction disorder.

Figure 1. Pulmonary embolism of the left and right proximal trunks with a small amount of left reaction pleurisy, right distal branch thrombus.

Figure 2. No pulmonary reaction on this Radiography.

Transthoracic Ultrasound showed a non dilated Left Ventricle (LV) with a 56% LV Ejection Fraction (LVEF), a paradoxical Interventricular Septum. The right ventricle was normokinetic TAPSE (Tricuspid Annulat Plane Systolic Excursion) at 21 mm, systolic pulmonary arterial pressure (SPAP) at 34 + 15 mm HG; an Inferior Vein Cave (IVC) dilated not very compliant. The pericardium was normal.

Biology: C-reactive protein (CRP) was 9 mg/l. Thrombocytopenia at 33,000 improved to 70,000 and then to 138,000/mm3. The renal status was normal. BNP (Brain Natriuretic Peptide) was high. Troponin was positive at 0.21 ng/ml.

The venous doppler of the lower limbs (VDLL) did not find deep vein thrombosis.

6. Treatment

The patient underwent anticoagulation with unfractionated heparin 300 mg/day in Electrical Injection Venous Intra (IVSE) with a target TCA of 2.5 in combination with previscan, analgesia with Nefopam, oral paracetamol, prevention of stress ulcer with Esomeprazole 20 mg, antibiotic therapy with ciprofloxacin.

7. Evolution

Favorable under treatment, clinically marked by the absence of chest pain, and by hemodynamic stability. From the biological point of view, the Blood Formula count had revealed platelets with 212,000 elements per mm3, an HB level of 12 g/dl and a hypokalemia of 3.4.

8. Discussion

This clinical case illustrates the following difficulties in an African context: the prevention and management of thromboembolic disease in a patient with thromboembolic risk factors associated with a risk of bleeding; management of unfractionated heparin in DIVC with severe thrombocytopenia; intermittent availability of blood products; the diffusion of medical information between the different specialties; the absence of a hematologist in the management of this patient.

This bleeding facilitated the uncontrolled systemic activation of the hemostatic system to simultaneous generalized microvascular thrombosis [7] leading to heart failure in our patient. The venous thrombotic risk major is based on risk factors realeted to the patient that are either transient (prolonged immobilization of more than 3 days, fractures of the lower limbs in the last 3 months, travel, hormones) or permanent [9] [10] . Our patient had three permanent risk factors: obesity, age (age > 35 years) and multiple pregnancies [11] [12] [13] [14] . Obesity has been recognized for decades as a major risk factor of cardiovascular and venous thromboembolic diseases [12] . As for pregnancy, the physiological changes (in particular those of hemostasis) make the pregnant woman a patient with a high thrombotic risk. From the third trimester of pregnancy, fibrinogen, factors VII, VIII, X, XII and von Willebrand increase [15] . Prothrombin II increases from early pregnancy to an average of 130% between 10th and 19th Weeks of Amenorrhea and then tends to return to normal. At the same time, there is an increase in the level of tissue plasminogen activator inhibitors [16] [17] . There could be at least two inhibitors of plasminogen activators (PAI 1 and PAI 2) in the maternal serum, one of which is derived from endothelial cells and the other from the placenta [18] . All inhibitors of plasmin formation increase during pregnancy with a consequent decrease in fibrinolytic activity during pregnancy [18] .

There is also a decrease in venous flow from the 25th week of amenorrhea to 6 weeks postpartum and a decrease in protein S [15] .

Uterine rupture, severe postpartum haemorrhage, massive transfusion of blood concentrate, associated with other risk factors present during pregnancy, have been the cause of hypercoagulability, hypo-fibrinolysis [2] . Initially, these modifications allow the maternal organism to prepare for delivery and to prevent the risk of uterine bleeding associated with delivery. On the other hand, they increase the risk of thromboembolic accidents and many studies suggest the existence of a certain degree of intravascular coagulation as early as the fifteenth week of pregnancy due to the increase of procoagulant factors and the reduction of thrombolytic activity [16] [19] . Acute obstetric bleeding in our patient has been associated with rapid consumption of coagulation factors and considered to be one of the main causes of disseminated intravascular coagulation (DIC) [20] [21] . Postpartum thromboprophylaxis should take into account the level of risk, especially when the order ratio (OR) becomes greater than 3 (age > 35, obesity, multiparity, urgent cesarean section and severe hemorrhage of post partum) [22] . In our study, in view of the abundant haemorrhage requiring a surgical procedure (OR = 12) [22] associated with a highly disturbed balance of coagulation, the prevention of postoperative thromboembolic disease could only be initiated to day four (September 10, 2017), which was contrary to formalized expert recommendations [4] [5] [8] [23] . It is the realization of a thoracic angioscanner as Gold standard practice, before any thoracic pain associated or not with dyspnea appearing in a context of obstetric surgery, [8] [10] [23] which allowed to make very early the diagnosis of pulmonary embolism. However, the absence of the D Dimer assay is noticeable because of the high clinical probability but also because physiologically we observe in pregnant women a very significant increase in these D Dimers [24] . Their utility to rule out a venous thromboembolic disease (VTE) is very limited until 4th week postpartum [25] . The initial severity of pulmonary embolism is assessed by the simplified Pulmonary Embolism Severity Index (sPESI), allowing the risk of death to be assessed within 30 days [10] [22] . It seems best validated to select patients at risk of early mortality [26] [27] [28] . This stratification score of early mortality risk makes it possible to classify our patient in the category of intermediate risk pulmonary embolism (stable hemodynamics, elevation of biological markers) with a score greater than or equal to 1 and therefore a mortality rate equal to 11%. The mangement is based on this assessment. The strategy adopted to manage a pulmonary embolism without shock with unfractionated heparin gave very good clinical results and the patient was discharged from her hospitalization of the intensive care unit on the third day.

9. Conclusion

This observation confirms the appearance of pulmonary embolism after an abundant haemorrhage requiring postpartum surgery. It highlights the importance of prevention of thromboembolic disease in the postpartum period and the implication of the physiological changes of pregnancy in the occurrence of this complication. Like all recent studies, it demonstrates the value of thoracic CT angiography for the diagnosis of pulmonary embolism, thus enabling an early management and improving the prognosis.
