Abstract

In patients with suspected pulmonary thromboembolism (PTE) clinical probability does not always correlate with the scintigraphic probability. The aim of this study was to compare the clinical and radiological findings in patients with suspected PTE and to assess the role of pulmonary vascular obstruction score (PVOS) in diagnosis. The data of 165 patients with suspected PTE who had undergone perfusion lung scan between 1998 and 2001 were examined retrospectively. Of the 165 patients investigated, 131 had the diagnosis of PTE, 34 had diagnosis other than PTE. The later was assigned as control group. When the clinical and scintigraphic data were compared no correlation was found in both groups. In 147 patients lung scans were scored according to PVOS. The patients with PTE had significantly higher PVOS when compared to control group (PVOS were 47.41, 18.93, p<0.001 respectively). In patients with PTE, PVOS increased in relation to the increase in clinical or scintigraphic probability, where no such relation was found in controls. Within all clinical and scintigraphic probabilities PTE patients had a minimum PVOS of 35.7, where the maximum PVOS was 26.6 in control group. We conclude that in patients with suspected PTE, whom the clinical and scintigraphic probability conflicts PVOS can be helpful in definite diagnosis.

Özet

Pulmoner tromboembolizmden (PTE) kuşkulanılan olgularda klinik hastalık olasılığı ile sintigrafik olasılık her zaman uyum göstermemektedir. Bu çalışmanın amacı, hastanemize başvurup PTE ön tanısıyla incelenen hastaların klinik ve radyonüklid inceleme (perfüzyon, ventilasyon sintigrafisi ve akciğer grafisi) bulgularının karşılaştırılması ve pulmoner vasküler obstrüksiyon skorunun (PVOS) tanıdaki yerini belirlemektir. 1998-2001 yıllarında hastanemizde PTE ön tanısıyla perfüzyon sintigrafisi çekilen 165 hastanın verileri geriye dönük olarak incelendiğinde, olguların 131'ine PTE tanısı, 34'üne ise PTE dışı tanı konulduğu görüldü. Bu 34 hasta kontrol grubu olarak kabul edildi. Olgularda klinik ve sintigrafik değerlendirme sonuçları karşılaştırıldığında, gerek PTE gerekse kontrol grubunda klinik ve sintigrafik olasılıkların her zaman uyumlu olmadığı görüldü. 165 hastanın 147'sinin perfüzyon sintigrafileri pulmoner vasküler obstrüksiyon derecesine göre skorlandığında PTE tanısı alan olgularla kontrol grubunun PVOS'lerinin oldukça farklı olduğu görüldü (sırasıyla 47.41, 18.93, p<0.001). PTE'li olgularda klinik ve sintigrafik olasılık arttıkça PVOS'nin arttığı, ancak kontrol grubunda böyle bir özellik olmadığı görüldü. Tüm klinik ve sintigrafik olasılıklar göz önüne alındığında PTE'li olgularda en düşük PVOS'nin 35.7 olduğu, kontrol grubunda ise 26.6'nın üzerine çıkmadığı görüldü. Sonuç olarak klinik ve radyonüklid değerlendirmelerle PTE tanısı konulmasında güçlük çekilen olgularda PVOS'nin yardımcı olabileceği kanısına varıldı.
