Mechanical Thrombectomy Using the Solitaire AB Device for Acute Embolic Mesenteric Ischemia.

Area of Science:

• Interventional Radiology
• Vascular Surgery
• Gastroenterology

Background:

• Acute mesenteric ischemia due to superior mesenteric artery (SMA) occlusion is a critical condition requiring rapid intervention.
• Traditional treatments carry significant risks and often have poor outcomes.
• Mechanical thrombectomy offers a less invasive alternative for restoring blood flow.

Purpose of the Study:

• To evaluate the preliminary efficacy and safety of mechanical thrombectomy using the Solitaire AB device with thromboaspiration for acute embolic SMA occlusion.
• To assess technical and clinical success rates, as well as complication profiles.
• To determine the impact on patient symptoms and the need for further interventions.

Main Methods:

• Retrospective review of 9 patients with acute embolic SMA occlusion treated between October 2015 and October 2017.
• Mechanical thrombectomy performed using the Solitaire AB device combined with manual thromboaspiration.
• Adjunctive stent implantation considered for stenosis or failed thrombectomy; technical and clinical success defined.

Main Results:

• Technical success was achieved in 100% of patients, with clinical success in 78%.
• All patients experienced significant pain relief; no device-related complications or distal embolization occurred.
• Bowel resection was avoided in all cases, with 11% in-hospital mortality. Median follow-up showed symptom-free survival and maintained stent patency.

Conclusions:

• Mechanical thrombectomy with the Solitaire AB device and thromboaspiration is a rapid, effective, and safe treatment for acute embolic SMA occlusion.
• This technique demonstrates promising preliminary outcomes in managing SMA ischemia.
• The procedure successfully restored SMA patency, preventing major complications and improving patient recovery.
