Portal vein thrombosis (PVT), a rare but serious complication after splenectomy, can lead to severe outcomes. Early diagnosis and aggressive treatment are crucial for managing this condition and preserving bowel viability.

Area of Science:

  • Gastroenterology
  • Vascular Surgery
  • Hematology

Background:

  • Portal vein thrombosis (PVT) is a known complication of hepatic disease and splenectomy, though its incidence is often underestimated.
  • Idiopathic thrombocytopenic purpura (ITP) is an autoimmune disorder characterized by low platelet counts, often treated with splenectomy when refractory to medication.

Observation:

  • A 19-year-old woman with ITP underwent laparoscopic splenectomy and initially recovered well.
  • Twenty-one days post-surgery, she developed nausea, vomiting, and leukocytosis, with CT scans revealing PVT and superior mesenteric vein thrombosis.
  • Despite medical management, her condition rapidly deteriorated, leading to extensive small bowel necrosis requiring multiple surgical interventions.

Findings:

  • Post-splenectomy PVT can present with vague symptoms and has a high risk of morbidity, as demonstrated by extensive bowel necrosis in this case.

  • Contrast-enhanced CT and color-flow Doppler are essential for nonoperative diagnosis of PVT.
  • Aggressive thrombolysis is the preferred treatment to improve outcomes and maintain bowel viability.

    • Implications:

    • This case highlights the critical need for heightened clinical suspicion for PVT in patients presenting with non-specific symptoms after splenectomy.
    • Prompt diagnosis and aggressive therapeutic strategies, including thrombolysis, are vital for preventing catastrophic complications like bowel infarction.
    • Further research into risk factors and optimal management protocols for post-splenectomy PVT is warranted.
