Directional Atherectomy for Critical Lower Limb Ischemia: A Retrospective Observational Study.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveChronic arterial obstructive disease of the lower limbs is a significant global health issue. Directional atherectomy offers advantages in treating critical ischemia. The objective of this study is to determine the clinical outcomes of patients with critical ischemia who underwent directional atherectomy using the TurboHawkdevice.
methodsA retrospective review was conducted at Alma Mater Hospital in Medellín, Colombia, on all medical records of patients with critical limb ischemia (Rutherford Classes V and VI) who underwent directional atherectomy for infra-inguinal arterial disease.
resultsA total of 42 atherectomies were performed in 41 patients, with 61% classified as Rutherford V and 24.4% as Rutherford VI. The average lesion length to be treated was 60 mm. Calcifications were found in 45.2% of cases, and predilatation angioplasty was used in 42.9% of cases. Atherectomy sites included femoropopliteal segment (40%), superficial femoral (29%), infrapopliteal vessels (14.2%), and more than one vessel in 50% of cases. Technical success was achieved in 78.6% of cases and procedural success in 97.6%, and the need for adjunctive conventional balloon angioplasty was 21.4%, while drug-coated balloon angioplasties were performed in 50% of limbs. The overall complication rate was 14.4%, with embolism at 4.8%, dissection at 4.8%, puncture at 2.4%, and perforation at 2.4%. The average follow-up duration was 12 months, and major amputations were required in 23.8% of cases. Improvement in ankle-brachial index to ≥0.1 was seen in 77% of limbs. Limb survival at 30 days was 85%, and at 90 days, it was 83%. The overall survival rate in the study was 79%.
conclusionsDirectional atherectomy is a safe alternative for managing critical ischemia in Rutherford V and VI patients.
