A New Technique for Mechanical Thrombectomy in Patients With Acute Pulmonary Embolism: A Case Series
Bibliographic record
Abstract
Acute PE is a serious illness that has a high mortality. Systemic anticoagulation, systemic thrombolysis, catheter-directed thrombolysis, and mechanical thrombectomy are the four main types of therapies used today for PE. The innovative "smart" catheter tubing system of the Penumbra Indigo System (Penumbra Inc., Alameda, CA) is aKeyon thrombectomy. Despite the Penumbra indigo system's effectiveness and thorough research, many governments-especially those in developing countries-are unable to use it because of its high cost and shortage. Here, we present a novel, homemade, inexpensive, and simple Penumbra-like technique (Marwan-Ayman Pulmonary Embolectomy "MAPE" technique) for thrombus aspiration in this case series. We substituted a Judkin right catheter 7 French for the Penumbra catheter, a three-lobed snare for the separator and the standard Y connector to connect to Amico vacuum suction device (Ontario, Canada) which substitute Penumbra engine and is adjusted at -29 mmhg. We used this procedure in four cases with excellent outcomes.

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.
