1 · What the graph read from it

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.

2 · The registry

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

purposeTo evaluate access site adverse events following ClotTriever-mediated large-bore mechanical thrombectomy via small upper extremity deep veins (< 6-mm). MATERIALS AND

methodsTwenty patients, including 24 upper extremity venous access sites, underwent ClotTriever-mediated large-bore thrombectomy of the upper extremity and thoracic central veins for symptomatic deep vein obstruction unresponsive to anticoagulation. Patients without follow-up venous duplex examinations (n = 3) were excluded. Patients who had > 6-mm diameter veins accessed (n = 3) were excluded. Temporary purse-string sutures and manual pressure were used for access site hemostasis in all patients. Vein access site and diameter, technical success (defined as placement of the 13.5-French ClotTriever sheath followed by thrombectomy), and early (< 30-days) and late (> 30-days) access site-related adverse events (according to the Adverse Event Classification by the Society of Interventional Radiology criteria) were recorded.

resultsFourteen patients (8 males, 6 females; mean age 51.7 ± 13.6 years) comprising 16 upper extremity venous access sites were included in this study. Access sites included: right brachial (n = 7), left brachial (n = 5), and bilateral brachial (n = 2) veins. The mean access site diameter was 4.3-mm ± 0.67-mm. Technical success was achieved via all access sites. Six (42.9%) patients underwent stent reconstruction following thrombectomy through the same accesses. After the procedure, all purse-string sutures were removed within 24 h. Three (21.4%) patients experienced small access site hematomas that did not require transfusion, intervention, or prolonged hospitalization. Initial follow-up venous duplex ultrasounds were performed at 29.3 ± 21.7 days following intervention. The mean follow-up interval to the second and third venous duplex ultrasounds were 124.3 ± 64-days and 225.1 ± 80.1 days, respectively. One (7.1%) patient developed right arm swelling six days after the procedure and was found to have thrombosis of the previously accessed right brachial vein. No other clinically or sonographically significant access site adverse events were observed.

conclusionClotTriever-mediated large-bore thrombectomy via small upper extremity veins is safe with minimal access site adverse events.
