Superior mesenteric vein (SMV) thrombosis is a rare complication of acute appendicitis. This case report details successful treatment with appendectomy, antibiotics, and anticoagulation, leading to complete thrombosis resolution.
Area of Science:
- Gastroenterology
- Vascular Surgery
- Internal Medicine
Background:
- Superior mesenteric vein (SMV) thrombosis is an uncommon condition.
- Acute appendicitis is a rare cause of SMV thrombosis.
Observation:
- A 21-year-old male presented with severe acute appendicitis complicated by SMV thrombosis.
- The patient underwent emergency appendectomy, broad-spectrum antibiotic therapy, and anticoagulation.
Findings:
- Intravenous heparin was transitioned to warfarin for anticoagulation.
- Computed tomography scan on postoperative day 45 confirmed complete dissolution of SMV thrombosis.
- Anticoagulation therapy was continued for 3 months without complications.
Implications:
- This case highlights the successful management of SMV thrombosis secondary to acute appendicitis.
- A multidisciplinary approach involving surgery, antibiotics, and anticoagulation is effective.
- Early diagnosis and treatment are crucial for favorable outcomes in rare cases of appendicitis-induced SMV thrombosis.
