Obstetrics Case Reports

published literature suggest that for young women of childbearing age who require AVR, the Ross procedure should be recognised as a safe operation with low operative mortality and favourable long-term results, which are unaffected by pregnancy and with only minimal adverse effects on maternal and fetal outcome.

Introduction Seizures in the postpartum period are not always due to eclampsia, and the various potential aetiologies have a considerable amount of overlap leading to difficulty in diagnosis. Massive pulmonary embolism (PE) as a cause of seizure in the postpartum period has not been previously reported. Herein, we describe a case of massive PE presenting with seizures in the immediate postpartum period, diagnosed utilising bedside transthoracic echocardiography (TTE) and successfully treated by surgical embolectomy.

Case report A 33-year-old, G3P2002, African-American woman presented for scheduled induction of labour at 39 weeks’ gestation, with a pregnancy complicated by malnutrition and anaemia. Her history was significant for gastric bypass surgery, from which the patient achieved a normal

body mass index prior to pregnancy. She did not have a current or remote history of tobacco use, pre-eclampsia, eclampsia, epilepsy or a family history of seizure disorder. Approximately 2 h after a spontaneous vaginal delivery, the patient experienced a postpartum haemorrhage, which was controlled by misoprostol and oxytocin. An hour later, she suddenly became unresponsive with development of myoclonic seizure activity. The patient was started on diazepam and fluid resuscitation, but she continued to deteriorate and went into pulseless electrical activity (PEA), for which cardiopulmonary resuscitation (CPR) measures were initiated. She was stabilised and prepared for transfer to the intensive care unit (ICU), but she again arrested with PEA approximately 5 min later, followed by CPR with return of spontaneous circulation (ROSC). During transport to the ICU, the patient arrested for a third time with PEA, and CPR was resumed until ROSC was achieved. Bedside TTE was performed revealing dilation of the right atrium (RA) and right ventricle (RV); severe tricuspid regurgitation (TR) and pulmonary hypertension; right ventricular dysfunction and an echodense lesion in the pulmonary artery, suggestive of acute saddle PE (Figure 1). As she had undergone a recent vaginal delivery and had experienced chest compressions, thrombolytic therapy was contraindicated. As such, she was brought to the operating room and underwent successful surgical pulmonary embolectomy with extraction of a large saddle embolus and placement of an IVC filter. A Bakri balloon for control of active uterine bleeding was also performed. The patient was started on levetiracetam to control post-hypoxic myoclonus activity (Lance-Adams syndrome) and head magnetic resonance imaging did not demonstrate any abnormalities. Anticoagulation therapy with warfarin was initiated on postoperative day (POD) 8 and was continued upon discharge. The remainder of the patient’s hospital course was uneventful, and she was discharged home on POD 22. The patient returned for her postpartum examination and was well except for some memory deficits.

Discussion Venous thromboembolism (VTE), a disease state inclusive of deep vein thrombosis (DVT) and PE, remains a leading cause of maternal morbidity and mortality in developed countries (Berg et al. 2010; Chang et al. 2003; Heit et al. 2005). Pregnant and postpartum women are at a four- to five-fold increased risk of developing VTE compared with non-pregnant women, with the highest incidence in the first week after delivery (Conti et al. 2013; Heit et al. 2005; James 2009; Baue 1986; Virkus et al. 2011). As such, prompt recognition and treatment of acute PE in this setting is paramount. However, the clinical presentation of acute PE can mimic the changes of normal pregnancy and various pathophysiological states, leading to potential delays in diagnosis and treatment. Acute PE can also present in unusual ways, such as seizures, which occur in less than 1% of cases (Meyer 2009). Although the pathophysiology of seizures in PE is not well-defined, Marine and Goldhaber (1997) theorised that seizures may arise from transient cerebral ischaemia, hypoxia and metabolic and respiratory acidosis resulting from the right ventricular and respiratory failure caused by the pulmonary embolus. The presented case emphasises several interesting aspects of acute PE in pregnancy and the postpartum period. In reviewing the literature, we did not find any previously reported cases of acute PE presenting as seizures in this population. However, the literature supports maintaining a high index of suspicion for PE in any patient presenting with seizures and abnormal vital signs that are not explained by the seizure activity alone (Volz and Jasani 2014). As our patient was haemodynamically unstable and did not have a history of seizures, PE was felt to be high in the differential. Our case also demonstrates the potential role of echocardiography in the diagnosis of PE in pregnancy. Current standards for imaging the pulmonary arteries presents risks for radiation and contrast agent exposure to mother and fetus. Echocardiography mitigates these risks while also providing the ability for expeditious evaluation. Additionally, while thrombolysis is currently recommended for the initial treatment of massive PE, recent evidence suggests that early surgical embolectomy may impart a greater survival benefit (Basciani et al. 2011). In summary, clinicians treating pregnant and parturient women

should maintain a high level of suspicion for PE, especially in the setting of unexplained new-onset seizures. Consideration should be given for the use of bedside echocardiography in diagnosing PE in pregnancy, as well as surgical embolectomy as a possible first-line treatment for patients with acute submassive or massive PE, though further study is warranted.

Introduction The rare presentation of Cushing syndrome during pregnancy prevents the use of established guidelines for management. A three-step dilemma challenges clinicians making this diagnosis: surveillance, medical or surgical treatment in the case of intervention, or open surgery or laparoscopy in the case of surgery. A critical analysis of each option is presented here, based on the clinical case of a woman who was diagnosed with Cushing syndrome during pregnancy and who underwent laparoscopic excision of a functional adrenal adenoma. Cushing syndrome is rare during pregnancy because frequent anovulation adds to an already uncommon process (5–25 cases per million/
