ABSTRACT

Preeclampsia is clinically defined by hypertension and proteinuria, with or without pathologic edema that occurs after 20 weeks' gestation, but can also present up to 4-6 weeks post-partum. Worldwide, incidence of preeclampsia is 5-14 percent of all pregnancies, while severe preeclampsia can develop to about 25 percent of all cases of preeclampsia. Severe preeclampsia is a pathology characterized by endothelial dysfunction that can often be complicated, and thus may lead to liver and renal failure, disseminated intravascular coagulopathy (DIC), and central nervous system (CNS) abnormalities. Worldwide, preeclampsia and eclampsia is responsible for about 14 percent of maternal deaths per year. We present a case, from our clinic, which has had serious complications after birth and that ended with the death of the patient. Despite the adequate management with the timely diagnosis and therapy, patient died ten days after Caesarean delivery.

Key words: severe preeclampsia; postpartum; complications

ABSTRACT

La preeclampsia se define clínicamente por la presencia de hypertension y proteinuria, con o sin edema patológico, y aparece luego de las 20 semanas de gestación, pero también puede presentarse de 4 a 6 semanas después del parto. En el ámbito internacional, la incidencia de la preeclampsia oscila entre 5 y 14 % de todos los embarazos mientras que la preeclampsia severa puede desarrollarse en el 25 % aproximadamente de todos los casos de preeclampsia. La preeclampsia severa es una patología que se caracteriza por la disfunción endothelial con complicaciones frecuentes y de ahi puede originarse la insuficiencia renal y hepatica, la coagulopatía intravascular diseminada y las anomalías en el sistema nervioso central. Ambos trastornos son responsables aproximadamente del 14 % de las muertes maternas en el mundo. Se presenta el caso de una paciente de nuestra clínica que sufrió graves complicaciones tras el parto y murió a consecuencia de ello. A pesar del cuidado adecuado, el diagnóstico y el tratamiento oportunos, esta paciente falleció diez dias después del parto por cesárea.

Pre-eclampsia is clinically defined by hypertension and proteinuria, with or without pathological oedema that occurs after 20 weeks' gestation, but can also present up to 4-6 weeks post-partum.¹

Severe features of Preeclampsia include any of the following features;

(a) Systolic blood pressure of 160 mm Hg or higher, or a diastolic blood pressure of 110 mm Hg or higher on two occasions at least 4 hours apart while the patientis on bed rest (unless antihypertensive therapy is initiated before this time).

(b) Thrombocytopenia (platelet count less than 100.000/microliter).

(c) Impaired liver function as indicated by abnormally elevated blood concentration of liver enzymes (to twice normal concentration), severe persistent right upper quadrant or [epigastric pain unresponsive to medication and not accounted by alternative diagnosis, or both.

(d) Progressive renal insufficiency (serum creatinine concentration greater than 1.1 mg/dl or a doubling of the serum creatinine concentration in the absence of other renal disease).

(e) Pulmonary edema.

(f) New-onset cerebral or visual disturbances.

Worldwide, incidence of pre-eclampsia is 5-14 percent of all pregnancies. In developing nations, incidence of pre-eclampsia is 4-18 percent.^2,3 Severe pre-eclampsia can develop to approximately 25 percent of all cases of pre-eclampsia.⁴ Morbidity and mortality in pre-eclampsia and eclampsia are frequent. Severe pre-eclampsia may lead to liver and renal failure, disseminated intravascular coagulopathy (DIC), and central nervous system (CNS) abnormalities. In world, preeclampsia and eclampsia is responsible for approximately 14 percent of maternal deaths per year (50,000-75,000). ⁵ A woman with severe preeclampsia, and complicated with eclampsia or HELLP syndrome, has a 20 % risk of developing preeclampsia in her subsequent pregnancy.^6-11

CASE PRESENTATION

A 34-year-old woman pregnant presented in Department of Obstetrics and Gynecology, University Clinical Centre of Kosovo, with 29 weeks'gestation and dyspnoea, expressed cyanosis, tachycardia, and epigastric pain. At the admission office, she had a blood pressure of 160/95 mmHg; pulse of 105 beats per minute, oxygen saturation was 96. On physical examination, congenital deformity of the spine (kyphoscoliosis) was noticed. Skin and mucous membranes were pale. Data from the history show that the patient was treated by easy preeclampsia, from week 25 of gestation. Laboratory findings; hemograme was normal, urine analysis (protein 1+). Biochemical laboratory tests: serum aspartate aminotransaminase (AST), 67 IU/L; serum alanine aminotransaminase (ALT), 120 IU/L; serum lactate dehydrogenase (LDH), 839 IU/L; serum urea 10.74 mmol/L and creatinine was normal; Triglyceride, 3.49mmol/L; hemoglobin and platelet count were normal. Coagulation profile was normal. After consultations with a cardiologist, anesthesiologist and pulmonologist, patient was found to be having acute pulmonary edema. Ultrasound and Echocardiography revealed pericardial effusion, and other parameters anatomical structure of the heart were found normal. Chest x-ray, electrocardiogram and all necessary imaging examinations were also performed. Patient was transferred to intensive care unit, where she was intubated and connected to the respiratory apparatus. The ultimate diagnosis: 29 weeks pregnant, Preeclampsia, Pericardial effusion, pulmonary edema, Respiratory insufficiency, Kyphoscoliosis, Neurofibromatosis, Rh incompatibility (Patient a week earlier, at week 28 of gestation was treated with 300 mcg of Rh IgG (RhoGAM), intramuscular injection). After stabilization of vital parameters for several hours, it was decided to terminate the pregnancy after a written consent of the patient. A Pfannenstiel incision was made and a female fetus was delivered weighing 1340 grams with Apgar score of 1 in the first minute and 3 in the fifth minute. The patient was treated with supplementary oxygen, crystalloid, antibiotics, H2- blockers, LMWH, B-blockers, diuretic, analgesic, vitamin preparations, mucolytics, corticosteroids,anti-hypertensive and antiemetic. After a week of treatment in intensive care unit, the patient's condition improved, and therefore was extubated and shifted back to the Department of Obstetrics and Gynaecology under monitoring of cardiologist, anaesthesiologist and pulmonologist. After seven days, patient's condition rapidly deteriorated and went into cardiac arrest. Despite the resuscitation measures taken, it unfortunately ended up in her death after 10 days of cesarean delivery postpartum (exitus letalis).

DISCUSSION

Preeclampsia is the disease of widespread vascular endothelial malfunction and generalized vasospasm. However, the pathophysiologic mechanism for preeclampsia is very complex. Severe preeclampsia can develop to approximately 25 percent of all cases of preeclampsia [4]. Worldwide, preeclampsia and eclampsia is responsible for approximately 14 percent of maternal deaths per year [5]. This disease may lead to liver and renal failure, disseminated intravascular coagulopathy (DIC), and central nervous system (CNS) abnormalities. Preeclampsia/eclampsia is one of the leading causes of maternal morbidity and mortality worldwide. Failure of clinicians to predict the impending life-threatening complications from preeclampsia may contribute to rise in maternal mortality due to this disease and its associated complications.

Early detection/diagnosis and appropriate management is extremely important in patients with preeclampsia, for better maternal as well as perinatal outcome.

Clinician must perform a detailed assessment along with thorough history taking (including the symptoms of severe preelampsia and physical examination. Laboratory tests such as a complete blood count with platelet count, and assessment of serum creatinine and liver enzymes levels, evaluation for urine protein (24-hour collection or protein/creatinine ratio) may aid to establish the diagnosis. Fetal evaluation should be performed including antepartum fetal surveillance.

Preeclampsia is a pregnancy-specific hypertensive disorder with multisystem involvement. Severe preeclampsia can result in both acute and long term complications for both the woman and her newborn. Maternal complications of severe preeclampsia include pulmonary edema, myocardial infarction, stroke, acute respiratory distress syndrome, coagulopathy, severe renal failure and retinal injury. These complications are more likely to occur in the presence of pre-existent medical disorders and with acute maternal organ dysfunction related to preeclampsia. Fetal and newborn complications of severe preeclampsia result from exposure to uteroplacental insufficiency or from preterm birth, or both. According to ACOG (2013), for women with severe preeclampsia at or beyond 34 0/7 weeks of gestation, and in those with unstable maternal-fetal conditions irrespective of gestational age, delivery soon after maternal stabilization is recommended.

This case report of patient who presented with 29 weeks of pregnancy with: dyspnoea, expressed cyanosis, tachycardia and epigastric pain to our clinical center. She developed complications associated with severe preeclampsia and unfortunately ended up with fatal outcome after 10 days of cesarean delivery post-partum, despite of timely diagnosis and adequate management.

Preeclampsia/ecclampsia is associated with substantial maternal complications, both acute and long-term. Clear protocols for early detection and management of hypertension in pregnancy at all levels of health care are required for better maternal as well as perinatal outcome.
