Endovascular management of femoral artery duplication with a proposed anatomical classification.

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
purposeDuplication of the femoral artery (FA) is an exceedingly rare anatomic variant, and its implications for endovascular therapy are poorly defined. We report endovascular revascularization for chronic limb-threatening ischemia (CLTI) in a duplicated FA and propose a classification system for these duplications.
methodsAn 80-year-old woman presented with lower extremity CLTI and underwent computed tomographic angiography (CTA) followed by endovascular treatment of the FA stenosis. In addition, previously published reports of FA duplication were reviewed to characterize anatomic patterns and inform a classification system.
resultsComputed tomographic angiography demonstrated a duplicated left FA with critical serial stenoses of the internal limb and severe disease near the distal confluence. Selective angiography confirmed two diminutive, parallel FA limbs with occlusion at the adductor canal near their coalescence and collateral reconstitution of the popliteal artery. The diminutive internal limb was successfully cannulated and used to traverse the occlusion. Orbital atherectomy followed by balloon angioplasty restored inline flow with minimal residual stenosis, resulting in durable limb salvage.
conclusionA duplicated FA can complicate endovascular recanalization because of the diminutive caliber of the arterial limbs. We identified five patterns of FA duplication in the literature. Type 1 represents partial duplication of the FA distal to the origin of the deep femoral artery, with subsequent reunion proximal to the adductor hiatus, a pattern similar to that observed in our patient. Including the present report, only 21 cases of type 1 FA duplication have been reported in the literature since the early nineteenth century.
