Overview
Portal vein thrombosis is a form of venous thrombosis affecting the hepatic portal vein, which can lead to portal hypertension and reduction in the blood supply to the liver.
Causes
Causes can include pancreatitis, cirrhosis, diverticulitis, and cholangiocarcinoma. It is also a known complication of splenectomy.[1] Drugs such as Romiplostim.
Diagnosis
The diagnosis of portal vein thrombosis is usually made by ultrasound, computed tomography with contrast or magnetic resonance imaging. D-dimer levels in the blood blood may be elevated as a result of fibrin degradation.
Treatment
-

Treatments include anticoagulants, shunts, bypass surgery, and transplants.

Reference list includes:[1][2]
| Disease | Similarities | Differentials |
|---|---|---|
| Meningitis | Classic triad of fever, nuchal rigidity, and altered mental status | Photophobia, phonophobia, rash associated with meningococcemia, concomitant sinusitis or otitis, swelling of the fontanelle in infants (0-6 months) |

| Substance abuse | Tremor, headache, altered mental status | Varies depending on type of substance: prior history, drug-seeking behavior, attention-seeking behavior, paranoia, sudden panic, anxiety, hallucinations |
| Electrolyte disturbance | Fatigue, headache, nausea | Varies depending on deficient ions; clinically, edema, constipation, hallucinations; on EKG, abnormalities in T wave, P wave, QRS complex; possible presentations include arrhythmia, dehydration, renal failure |
