Pre-closure of femoral venous access sites used for large-sized sheath insertion with the Perclose device in adults undergoing cardiac intervention: Figure 1
Bibliographic record
Abstract
BACKGROUND: Interventional procedures in adults with congenital cardiac conditions often require insertion of large-sized sheaths into the femoral veins. Data on the use of suture-mediated devices for femoral venous access site closure are scant and no data are available regarding venous patency after device use. OBJECTIVE: To assess the efficacy of the 6Fr Perclose (Abbott Vascular Devices, CA, USA) suture-mediated device in achieving haemostasis and venous patency after closure. DESIGN AND SETTING: 146 consecutive patients (80 women, mean (SD) age 45 (14) years) undergoing closure of 205 femoral venous access sites in a tertiary cardiac centre were studied. All received heparin and were taking concomitant aspirin or clopidogrel, or both. The majority (98%) had a >or=10Fr sheath inserted. RESULTS: Immediate haemostasis was achieved in 202 (99%) sites. Two patients (1.4%) had a major complication. On follow-up (111 patients, mean (SD) 71 (33) days) there was no evidence of haematoma or fistula formation. Doppler studies from a subgroup of 43 (29%) patients (mean (SD) age 45 (15) years, mean (SD) follow-up 47 (18) days) showed a common femoral venous diameter of 11.6 (2.7) mm on the device closed right and 12.2 (2.5) mm on the left vein (p>0.05). All accessed veins were patent with no pseudoaneurysm or arteriovenous fistula formation. CONCLUSION: Pre-closure of large-size sheath femoral venous access sites using the suture-mediated Perclose device is efficacious in achieving rapid haemostasis in the presence of anticoagulation. Doppler follow-up shows no loss of venous patency or luminal venous diameter as compared with the contralateral side.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
