- Definition:
- Causes:
1.Liver cirrhosis (Com.).
2.Extra hepatic portal v. occlusion.
3. Intra hepatic veno occlusive Dis.
4.Occlusion of hepatic vein.
- Presentation:• Decompensated Ch. Liver Di.• Ascites.• Encephalopathy.• Variceal bleeding.
I - General Resuscitation:
1 . Central venous access.2 . Blood preparation.3 . Vit. K injection (10 mg I.V.).4 . Correction of coagulopathy.5 . Correction of thrombocytopenia.6 . Endoscopic evaluation.7 . Avoid bronchial aspiration.8 . Sengestaken – Blakemore tube.
N.B.
• Severity of bleeding.
• Liver cirrhosis.
• Sengestaken – Blakmore tube.
Oesophageal aspiration channel
Oesophageal balloon20-30 mmHg greater than predetermined pressure
Gastric balloon at least 300 ml at 300 ml
Gastric aspiration channel
II - Drugs for variceal bleeding:
1 . Vasopressin / 20 units in 10ml 5% D/W.
over 10 minutes.
2 . Nitroglycerine / 40 g/min.
3 . Octreotide.
III - Endoscopic treatment of varices:
1 . Sclerotherapy.
2 . Banding.
IV - Tipss
- Indication.
- Procedure.
- Complications.
- Contraindication.
V - Surgical shunts
- Indication.- Types:
1 . Selective (splenorenal).2 . Non selective (portosystemic).
• Perforation of liver.• Occlusion.• Encephalopathy.• Stenosis
Surgical shunts (a-d). Surgical treatments for portal hypertension involve shunting portal blood into the systemic veins. This commonly involves (a) a side-to-side proto-caval anastomosis. (b) end-to-side porto-caval, (c) meso-caval or (d) spleno-renal.
N.B.
• Prophylactic shunting.
• Emergency shunts.
VI - Oesophageal stapled transection.
VII- Variceal bleeding and liver transplant.
