About this study
Official title: Thrombolysis With Intra-arterial Urokinase for Acute Superior Mesenteric Artery Occlusion: Outcome Analysis
Patients with acute superior mesenteric artery (SMA) occlusion were included in this study. The clinical presentation and effect of the recanalization of the SMA was analyzed on follow-up angiography.
Read the detailed description
Thirteen patients with acute SMA occlusion who underwent intra-arterial urokinase thrombolysis between 2008 and 2020 were retrospectively evaluated.
Clinically, the abdominal pain and the effect of the SMA on angiography will be compared in response and non-response groups.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
intra-arterial urokinase thrombolysisProcedure or surgery
Under local anaesthesia, the right femoral artery was punctured in accordance with the Seldinger technique, and a 6-Fr sheath, 10 cm in length, was implanted. Selective catheterization of the SMA was performed with 4-Fr catheter. The SMA angiography was performed to identify the filling defect. Thrombolysis was performed using a 5-Fr multiple-sideport infusion catheter (100cm with sideport of 7cm, 14 ports or 100cm with sideport of 15cm, 30 ports, Cook, Bloomington, IN, U.S.A). The tip of the microcatheter was embedded in the thromboembolism, which was fragmented at the time of thrombolysis. Thrombolysis was performed locally in the SMA with a bolus of urokinase
| Study group | Role | What they receive |
|---|---|---|
| According to the degree of occlusion, 13 patients were divided into complete and incomplete groups. | Seven patients were complete occlusion and 6 patients were incomplete occlusion and all underwent thrombolysis with intra-arterial urokinase and the outcome was analysed.. Receives: Procedure: intra-arterial urokinase thrombolysis |
What is being measured
The primary outcome is the main question the study is designed to answer.
Thrombolysis with intra-arterial urokinase for acute superior mesenteric artery occlusion: Outcome analysis
Degree of patency and appearance of the SMA will be analyzed in the follow-up angiography.
Measured: Daily series follow-up angiography in the next 72 hours after thrombolysis with intra-arterial urokinase.

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04688879, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
