Value of Computer Tomography in the Detection of Bullae and Blebs in Patients with Primary Spontaneous Pneumothorax

Abstract: In this prospective study, the value of computed tomography (CT) in detecting bullae and bleb formation of the lung in 35 patients with primary spontaneous pneumothorax (PSP) has been determined. The ability of CT in the detection of bullae and bleb formation and fibrotic changes is compared with the chest film in PSP. CT showed pathological lung changes in 31/35 patients. In most cases, few (n < 5) and small blebs (i.e., < 2 cm in diameter) were found. In 16/35 cases, blebs ( < 2 cm) and bullae ( > 2 cm in di… Show more

“…The role of blebs/bullae as a preexistent lesion for development of PSP has been questioned; in fact, some studies observed no correlation between its presence and the risk for PSP recurrence (6,8,9,11,12,(14)(15)(16)(17). However, there is some evidence on the lack of association between blebs and different recurrent patterns of PSP (ipsilateral or contralateral).…”

“…This observation is supported by articles that reported that blebs and bullae were detected in over 80% PSP patients treated with VATS [17][18][19]. In addition, there are some studies that reported that emphysema-like changes were detected by high-resolution CT in 80% of patients with a first episode of PSP [20,21].…”

“…No entanto, os estudos sobre a utilização de TCT nos casos de pneumotórax espontâneo não demonstraram correlação entre os achados morfológicos, como número e tamanho de bolhas, blebs, bolhas contralaterais ou fibrose envolvendo o parênquima pulmonar, e os índices de recorrência. Nesse sentido, a TCT nos casos de PEP, como método orientador da indicação de cirurgia, não deve ser utilizada rotineiramente (13)(14)(15) . Estabelecida a indicação de tratamento cirúrgico, impõe-se a questão: qual o melhor método?…”
