İnternal Torasik Arter Kullanılmış Koroner Baypaslı ve Aortik Ark Çıkımlı Vertebral Arter Olgusunda Subklavyan Çalma Sendromu: Bir Olgu Sunumu
Bibliographic record
Abstract
Koroner subklavyan çalma sendromu ilk kez 1974 yılında Harjola ve Valle tarafından bildirilmiştir. Proksimal subklavyan tıkayıcı hastalığından dolayı vertebral arterdeki tersine akım ve daha önce yapılmış LAD’ye (sol anterior desending) - internal torasik arter anastomozu, bu hastalarda koroner ve serebrovasküler yetmezliğe neden olur.68 yaşında erkek hasta, hafif baş dönmesi ve Kanada klas I – II anjina ile hastaneye başvurdu. DSA görüntülemesinde sol subklavyan arter tıkanıklığı, sol internal karotis arter darlığı ve aortik ark çıkımlı sol vertebral arter saptandı.Koroner – subklavyan çalma sendromu nadirdir fakat İTA kullanılmış koroner baypaslı hastalarda potansiyel olarak tehlike arz eder. Koroner arter hastalığı ve büyük damar tıkayıcı hastalığı birlikteliği koroner ve serebral vasküler yetmezlik kombinasyonunu getirebileceğinden, tam klinik ve radyoljik değerlendirme zorunludur.Anahtar kelimeler: Subklavyan çalma sendromu, koroner baypas, aortik ark çıkımlı vertebral arterSubclavian Steal Syndrome in a Coronary Bypass Patient with Vertebral Artery Originating From Aortic Arc and Internal Thorasic Artery Used as a Conduit: A Case ReportCoronary subclavian steal syndrome was first reported by Harjola and Valle in 1974. The reversal of flow in the vertebral artery due to proximal subclavian artery occlusive disease and in a previously constructed left internal thoracic artery (ITA) to left anterior descending coronary artery (LAD) caused coronary and cerebrovascular insufficiency in the patient. A 68 year – old man was admitted to the hospital with symptoms of dizziness and Canadian clas I–II angina. He had a history of coronary artery bypass grafting. Physical examination was consistent with subclavian steal syndrome. Digital subtraction angiography (DSA) demonstrated occlusion of the left subclavian artery, left internal carotid artery stenosis and left vertebral artery originated from the aortic arch.The coronary - subclavian steal syndrome tends to be a rare, but potentially hazardous, situation for patients after coronary bypass procedure with ITA grafts. The combination of coronary and cerebrovascular insufficiency is suggestive of concomitant CAD (coronary artery disease) and occlusive disease of the great vessels and mandates a full clinical and radiologic evaluation.Key words: subclavian steal syndrome, coronary artery bypass grafting, left vertebral artery originated from the aortic arch

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
