Endovascular treatment of acute limb ischemia for persistent sciatic artery aneurysms: a report of 2 cases.
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 1 paper.
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
backgroundPersistent sciatic artery (PSA) is a rare congenital anomaly associated with various complications, including atherosclerotic changes and aneurysms. These changes can cause limb ischemia, thrombosis, distal embolization of the PSA, rupture of aneurysms, buttock pain, and sciatica due to compression of adjacent tissues. Acute limb ischemia (ALI) is a life-threatening condition. Treatment of ALI includes surgical and endovascular treatments (EVT); EVT includes catheter-directed thrombolysis (CDT) and angioplasty, with thrombolysis being highly effective. In Japan, urokinase is the only insurance-covered thrombolytic agent approved for ALI treatment; however, it is currently unavailable due to manufacturing issues. CASE PRESENTATION: This case report details the treatment of two women (aged 89 and 82 years) with ALI associated with PSA. In both cases, reperfusion was achieved without CDT and stent grafts were deployed across the PSA aneurysm. The final angiogram showed that the PSA aneurysms had disappeared, and the vessel runoff was maintained. Both patients were successfully discharged from the hospital and experienced no complications over the next 6 months.
conclusionsTwo patients with ALI with PSA were treated with EVT without CDT. These cases suggest that EVT without CDT may rescue ALI caused by PSA. Moreover, no standard treatment for sciatic artery remnants has been established. Endovascular treatment with stent grafts may be an option for older patients.
