Bronkopulmoner 'Psödo' Sekestrasyon

Bronkopulmoner sekestrasyon terimi geniþ bir bronkopulmoner vasküler malformasyon spektrumunu içerir. Çölyak arterin dalýndan kanlanan, normal sað akciðer alt lobu olan asemptomatik bir olguyu sunuyoruz. Yirmi üç yaþýnda asemptomatik, sigara içmeyen, erkek askeri personel rutin saðlýk kontrolü için baþvurdu. Kontrastlý toraks bilgisayarlý tomografisinde (BT) sað akciðer alt lobun kanlanmasýný çölyak arterden aldýðý tespit edildi. Konjenital bronkopulmoner psödosekestrasyon olarak deðerlendirildi ve solunum semptomu olursa baþvurmasý önerildi. Bronkopulmoner sekestrasyon tanýmý Pryce tarafýndan yapýlmýþ ve üç grupta toplanmýþtýr. Tip I: Normal bir akciðer lob/segmentinin anormal sistemik kanlanmasýnýn olmasý, Tip II: Akciðerden baðýmsýz olan akciðer dokusu ve komþu normal akciðerin anormal sistemik kanlanmasýnýn olmasý, Tip III: Normal trakeobronþiyal sistemden baðýmsýz olan iþlevsiz akciðer dokusunun anormal sistemik kanlanmasýnýn olmasýdýr. Daha sonra Pryce Tip I sekestrasyon 'psödosekestrasyon' olarak adlandýrýlmýþtýr. Konjenital psödosekestrasyon en sýk alt loblarda görülür ve kanlanma desendan torasik aorta, çölyak arter veya abdominal aortanýn bir dalýndan kaynaklanýr. Tanýda BT en iyi yöntemdir.

Bronchopulmonary 'Pseudo' Sequestration

The term “pulmonary sequestration” refers to a wide spectrum of bronchopulmonary vascular malformations. In this case report, we present an asymptomatic case with a normal right lower lobe supplied by a branch of the celiac artery. A 23-year-old male member of the military applied for a periodical physical examination. A thorax computerized tomography (CT) scan revealed a normal right lung volume, although the right lower lobe received its blood supply from the celiac artery. A diagnosis of a congenital pseudosequestration was made, and the patient was advised to seek treatment should pulmonary symptoms develop. Bronchopulmonary sequestration was first described by Pryce, who distinguished between three types of developmental abnormality: Type I: A normal lung with anomalous systemic arterial supply, Type II: An anomalous artery supplying a disconnected lung and an adjacent normal lung, and Type III: A nonfunctional and abnormal lung with systemic arterial blood supply. Later, the Pryce Type I sequestration was renamed ‘pseudosequestration’. Congenital pseudosequestration is usually seen the in the lower lobes, and anomalous systemic blood supply arises from the descending thoracic aorta, celiac trunk or abdominal aorta. CT is the best diagnostic method.
