The
patient whose x-ray and CT scan images are shown has severe chronic obstructive
lung disease and a cavitary lesion. The
measured FEV1 is 0.6 liters. The
patient has been experiencing persistent daily hemoptysis and there have been
two episodes of massive hemoptysis. The
best definitive management of this problem is
A.
amphotericin intravenously.
B.
cavernostomy and muscle flap.
C.
intracavitary amphotericin.
D.
right upper lobectomy.
E. tube thoracostomy.
Answer
B
The
development of an aspergilloma in a cavitary lesion of the lung is commonly
associated with hemoptysis. Cavities
have been classified as simple or complex based on the condition of the
surrounding lung. A simple cavity
has little destroyed lung associated with it whereas complex cavities are
associated with extensive destruction of surrounding lung.
Treatment options are limited in patients with marginal pulmonary
function. Amphotericin is helpful
in invasive fungal infection, but it is not efficacious in treating cavitary
lesions such as aspergillomas. It
has no benefit in treating hemoptysis, especially massive hemoptysis.
Cavernostomy and transposition of extrathoracic muscle has been shown to
be effective treatment and is associated with fewer complications and lower
mortality rates than pulmonary resection for complex aspergillomas.
The Mayo Clinic reported complications following thoracotomy in 78% of 32
patients with complex aspergilloma compared to 33% in 21 patients with simple
aspergilloma. Operative mortality was 34% for complex cavities and 5% for
simple aspergilloma. Intracavitary
amphotericin has been tried with limited success in treating aspergillomas.
Because of limited success and complications, it has almost been
abandoned. It has no role in the
management of massive hemoptysis secondary to aspergilloma.
Tube thoracostomy or cavernostomy
alone is not definitive treatment and the rates of rebleeding are high.
