Subcapsular Liver Haematoma in Pregnancy
On this page
Direct answer
Subcapsular liver haematoma is a collection of blood beneath the liver capsule, usually linked to HELLP syndrome or severe pre-eclampsia in late pregnancy or the puerperium. It causes right upper quadrant or epigastric pain with shoulder-tip pain, and rupture produces hypotension and shock. Management is maternal stabilisation after correcting coagulopathy, then conservative care for stable, unruptured haematomas, and angioembolisation or surgery when bleeding is active or the capsule has ruptured.
What you must remember
- Association: Most cases occur with HELLP syndrome or severe pre-eclampsia, usually in the third trimester or early puerperium.
- Presentation: Right upper quadrant or epigastric pain, shoulder-tip pain from diaphragmatic irritation and a tender liver edge; rupture causes hypotension and shock.
- Diagnosis: Ultrasound is the first test, and contrast-enhanced CT or MRI defines the size, extent and any active bleeding.
- Pathogenesis: Periportal haemorrhagic necrosis and sinusoidal damage in HELLP are thought to cause bleeding beneath the capsule.
- Early priority: Resuscitation with crossmatched blood, and correction of platelets, fibrinogen and clotting factors before any intervention.
- Conservative care: Small, stable, unruptured haematomas are watched with serial haemoglobin, pain assessment and repeat imaging.
- Definitive care: Angioembolisation suits stable patients with active bleeding; laparotomy with packing, suturing or hepatic artery ligation suits rupture or instability.
- Delivery: The baby is delivered once the mother is stabilised, with treatment of HELLP and magnesium sulphate for seizure prophylaxis.
A stepwise route from suspicion to intervention
A woman with HELLP syndrome at 35 weeks develops sudden epigastric pain and a falling haemoglobin. The steps below set the order in which the team acts, because delay in imaging or in correcting coagulopathy can be dangerous.
- Suspect early: Any woman with HELLP or severe pre-eclampsia who develops upper abdominal pain, shoulder-tip pain or unexplained shock needs urgent liver imaging.
- Resuscitate first: Two large-bore cannulae, crossmatched blood and crystalloid, with platelets and fibrinogen checked and corrected before any procedure.
- Image the liver: Ultrasound identifies the collection, and contrast CT defines its size, extent and active bleeding, which decides the next step.
- Protect the mother and baby: Control blood pressure, give magnesium sulphate and plan delivery once the mother is stable, rather than delaying it indefinitely.
- Choose conservative care when safe: A small, stable, unruptured haematoma is monitored with serial haemoglobin, pain assessment and repeat imaging.
- Intervene for rupture or instability: Angioembolisation suits stable patients with active bleeding, while laparotomy with packing or hepatic artery ligation suits unstable patients.
Local expertise decides whether embolisation or surgery is available, and the choice is made jointly by obstetric, surgical and interventional radiology teams.
Where the exam tries to catch you
Vignettes usually describe HELLP and then test the next step.
- Trap: Choosing immediate laparotomy for every haematoma. Correct: Small, stable, unruptured haematomas are managed conservatively, and surgery is kept for rupture or instability.
- Trap: Treating right upper quadrant pain in a pre-eclamptic woman as gastritis or biliary colic. Correct: In pre-eclampsia or HELLP, upper abdominal pain is a liver emergency until imaging proves otherwise.
- Trap: Operating before correcting coagulopathy. Correct: Platelets, fibrinogen and clotting factors are corrected first, since bleeding at surgery or embolisation can be massive.
Frequently asked questions
Which condition is most often linked to subcapsular liver haematoma in pregnancy?
HELLP syndrome is the condition most often linked to subcapsular liver haematoma in pregnancy. Severe pre-eclampsia and eclampsia can also be responsible, and the haematoma usually declares itself in the third trimester or early puerperium.
What imaging is preferred for suspected subcapsular liver haematoma?
Ultrasound is the first screening test for suspected subcapsular liver haematoma, but contrast-enhanced CT gives the best definition of its size and any active bleeding. MRI is a reasonable alternative where radiation is a concern.
When is conservative management appropriate for a subcapsular liver haematoma?
Conservative management suits a subcapsular liver haematoma that is small, unruptured and haemodynamically stable, with close monitoring. Falling haemoglobin, rising pain or new instability should prompt a reconsideration of intervention.
What surgical options exist for a ruptured subcapsular liver haematoma?
A ruptured subcapsular liver haematoma may be treated with laparotomy, packing, suturing of the capsule, hepatic artery ligation or, rarely, partial hepatectomy. Angioembolisation is preferred in stable women with active bleeding where it is available.
Why must coagulopathy be corrected before liver intervention?
Coagulopathy in HELLP syndrome can make bleeding from a subcapsular liver haematoma severe and difficult to control. Correcting platelets, fibrinogen and clotting factors reduces the risk of massive haemorrhage during surgery or embolisation.
