Direct anastomosis indwelling needle puncture: a rapid and safe transitional hemodialysis access for patients with renal failure.
Article in Renal failure, 2025. 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
objectivesVascular access thrombosis (VAT) is a common complication in patients with end-stage renal disease (ESRD), significantly impacting hemodialysis efficacy and patient survival. Currently, temporary dialysis access is typically established
methodsBetween March 2023 and March 2024, patients VAT were recruited at Sir Run Run Shaw Hospital of Zhejiang University School of Medicine to undergo DAINP. Clinical data, including age, gender, dry and wet body weight, and blood biochemical parameters, were collected. Patient VA types, locations, and insertion vessels were documented. Detailed assessments and records of VAT were performed for all patients, including the distance of thrombus from the anastomosis, residual blood flow at the VA anastomosis, and corresponding selection of the DAINP insertion site. Ultrasound was utilized to measure and record the puncture depth. Concurrently, clinical data of patients undergoing venous catheterization (VC) for temporary dialysis access were collected. The operative time for both groups, defined as the interval from ultrasound assessment initiation to completion of the procedure, was recorded and compared.
resultsA total of 74 patients successfully underwent DAINP, with a 100% puncture success rate. Among them, 20 patients had residual blood flow at the VA stump, and the distance between the anastomosis and arterial flow was ≥ 1 cm. Patients with VA located at the elbow demonstrated the greatest puncture depth. Moreover, the operative time for the DAINP group was significantly shorter compared to the 17 patients who underwent VC for VAT during the same period. However, patients with VA located in the groin required a longer operative time for DAINP.
conclusionsThis study demonstrates that DAINP provides a rapid and safe method for establishing temporary hemodialysis access in VAT patients, effectively reducing the invasiveness and risks associated with traditional VC.
