Spontaneous unscarred uterine rupture in a primigravid patient at 11 weeks of gestation managed surgically: A rare case report

INTRODUCTION: Spontaneous rupture of the primigravid uterus is a rare but catastrophic obstetrical emergency. It usually occurs late in pregnancy or during labour, mainly in multiparous women. But, spontaneous unscarred uterine rupture in a primigravid patient that also in first trimester is very rare. There are only 12 papers in Pub Med database regarding spontaneous unscarred uterine rupture in primigravid in early pregnancy. CASE PRESENTATION: A 23-year-old primigravid female at 11th week of pregnancy, with no significant medical or surgical history, presented with sudden onset of generalised abdominal pain for four hours with multiple episodes of vomiting. On physical examination, patient was pale, in haemorrhagic shock with diffuse abdominal tenderness. Ultrasonography showed extra uterine gestational sac with massive haemoperitoneum. Eventually, patient was subjected to emergency laparotomy after resuscitation. CLINICAL DISCUSSION: Spontaneous rupture of unscarred gravid uterus is a catastrophic rare condition that can be missed leading to maternal and foetal mortality. There are no pathognomonic features indicating the condition therefore it should be differentiated from other causes of acute abdominal emergencies. CONCLUSION: Spontaneous rupture of unscarred gravid uterus should be differentiated from other acute abdominal emergencies. Patient may land up in emergency department in the state of shock, emergency physicians should be aware of its symptoms or presentations.
