Analysis of Doppler ultrasonography and computer tomography angiography for predicting amputation level and re-amputation rate.

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
objectivePeripheral arterial disease of the lower extremities is one of the most common causes of non-traumatic lower extremity amputation. Computed tomography (CT) angiography and Doppler ultrasonography are mainly used to evaluate distal vascular structures. Our objective was to evaluate the predictive efficacy of Doppler ultrasound and CT angiographic radiographic examinations in determining amputation levels and reamputation rates in patients undergoing lower extremity amputation.
methodsPatients with major or minor amputation at various levels due to lower extremity lesions were included in the study. Standard demographic information, clinical accompanying diseases, reamputation datas, Doppler ultrasound, and CT angiography radiological evaluation reports were obtained retrospectively from the hospital system records of the patients.
resultsA total of 166 cases including 119 (71.7%) males and 47 (28.3%) females were included in the study. About 36.7% (n=61) cases had amputation at the level of surgery above the knee, 38.6% (n=64) below the knee and 24.7% (n=41) at the level of foot/finger. In patients who underwent amputation above the knee, occlusion was seen at the level of the iliac artery (88.9%), femoral artery (47.8%), and popliteal artery (37%). The rate of occlusion at the level of the popliteral artery in patients with below-knee amputation (59.3%) was found in patients with foot/finger amputation (51.5%) at the levels arteria dorsalis pedis and posterior tibial artery. According to the level of occlusion at all blood flow levels, it was observed that the rate of reamputation was most common in occlusions at the level of popliteal artery.
conclusionIt was found that radiological data are effective in planning amputation according to blood flow level and does not make any difference per se. It was found that the reamputation rates were related to the determination of the level of blood flow in the primary surgical phase.
