FRÆÐIGREINAR
SJÚKRATILFELLI
horf. í okkar tilfelli sást þetta greinilega í aukningu
á fráblástursrúmmáli þar sem FVC-gildi hækkuðu
um 22% og FEVl-gildi um 18% (tafla I). Árangur
aðgerða virðist vera betri eftir því sem blöðrurnar
eru stærri og staðbundnari og oftast er árangurinn
viðvarandi (2, 4, 14, 16). Hjá sjúklingum með út-
breidda lungnaþembu er langtímaárangur síðri og
sumum þessara sjúklinga er ekki treyst í aðgerð
vegna þess hversu lungnastarfsemi er skert. I
þeim tilvikum kemur til greina að koma fyrir ein-
stefnuloka í berkjutréð í berkjuspeglun og tæmast
blöðrurnar þá við útöndun. Þetta er nýtt meðferð-
arúrræði og virðist lofa góðu (17).

A 49 year old male with a giant pulmonary bulla
- a case report and review of the literature
A 49 year old previously healthy smoker was diagnosed
with a giant bulla in his right lung, following a history of dry
cough, repeated upper airway infections and increasing
dyspnea for several years. Computed tomography (CT)
confirmed the presence of a giant bulla in the right inferior
lobe and several smaller bullae in the right superior
lobe. The giant bulla was 17 cm in diameter, occupying
more than half of the right hemithorax. On spirometry a
moderate restrictive and a mild obstructive pattern was
observed. Lung volume was measured with two different
techniques, nitrogen washout and plethysmography, with
volume of the bullae estimated at 2.9 L, similar to the 3.2
L determined by CT. The patient underwent thoracotomy,
where the giant bulla together with the inferior lobe
were removed with lobectomy and the small bullae in
the superior lobe with wedge resection. Five months
postoperatively the patient is in good health and is back
at work. Postoperatively significant improvements in
spirometry values and lung volume measurements have
been documented. This case demonstrates that giant
bullae can be successfully managed with surgical resection
and their size can be determined by different techniques,
including lung volume measurements and chest CT.
Key words: Giant buila, diagnosis, treatment, thoracotomy, iung voiume measurements.
