Endovascular management of acute superior mesenteric vein thrombosis: a retrospective study on thrombolysis outcomes.
Article in CVIR endovascular, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAcute superior mesenteric vein thrombosis (ASMVT) is a rare but life-threatening condition associated with high morbidity and mortality. While anticoagulation remains the standard treatment, endovascular therapies such as thrombolysis, thrombectomy, and angioplasty are increasingly utilized in selected cases. However, evidence on their outcomes remains limited. This study retrospectively reports the clinical outcomes of ASMVT patients treated with endovascular combination therapies.
methodsBetween August 2019 and May 2024, 12 patients (males = 9; mean age, 52.33 ± 12.51 years) were diagnosed with ASMVT. The study collected comprehensive data on demographic details, presenting symptoms, etiology, treatment modalities, response to treatment, and follow-up outcomes. Computed Tomography (CT) was available from diagnosis, and an average of 6.3 CT scans with a median follow-up of 3 months (IQR: 2-20 months).
resultsThe average time from symptom onset to angiographic treatment initiation was 8.0 ± 4.71 days, preceded by anticoagulation with heparin from the time of diagnosis. Patients were treated with combination therapy involving endovascular thrombolysis, rheolytic thrombectomy, and balloon angioplasty via transjugular (n = 9, 75%) or percutaneous (n = 3, 25%) approaches. Thrombolysis was performed with an average recombinant tissue plasminogen activator (rt-PA) infusion duration of 2.75 ± 1.14 days and a total dose of 61.25 ± 18.48 mg rt-PA. Superior mesenteric vein (SMV) flow was initially restored almost completely in 58.3% and partially in 41.7% of patients. Complications observed were hepatic artery bleeding (n = 2, 16.7%), hepatic arteriovenous fistula (n = 1, 8.3%), hepatic parenchymal bleeding (n = 1, 8.3%), melena (n = 1, 8.3%), and nostril bleeding (n = 1, 8.3%). Two patients experienced worsening symptoms of post-intervention, leading to bowel resection revealing intestinal necrosis. SMV patency was almost complete in 25%, and partially in 25% of patients at follow-up.
conclusionEndovascular combination therapy with long-term thrombolysis and thrombectomy in patients with ASMVT demonstrated promising technical outcomes. In view of complications, individual indication for intervention needs to be confirmed in a multidisciplinary team.
