Clinical Report: Successful Endovascular Intervention for Acute Thrombosis

Overview

This case study presents a 44-year-old male with acute thrombosis of the superior mesenteric and portal veins, leading to small intestinal necrosis. Successful endovascular intervention was performed, resulting in vascular recanalization.

Background

Acute superior mesenteric vein thrombosis (ASMVT) and acute portal vein thrombosis (APVT) are rare but serious conditions that can lead to significant morbidity and mortality if not treated promptly. Traditional management often involves emergency laparotomy.

Data Highlights

No numerical data or trial data available in the article.

Key Findings

• A 44-year-old male presented with acute abdominal pain and was diagnosed with complete thrombosis of the superior mesenteric vein and portal vein.
• Emergency endovascular intervention included percutaneous transhepatic portal venography, balloon dilation, thrombolysis, and thrombectomy.
• The patient underwent catheter-directed thrombolysis (CDT) postoperatively and achieved vascular recanalization by postoperative day 9.
• The intervention successfully avoided the need for surgical bowel resection.

Clinical Implications

Clinicians should consider endovascular therapy in cases of ASMVT and APVT.

Conclusion

Endovascular intervention for acute thrombosis of the superior mesenteric and portal veins can prevent intestinal necrosis.
