Prognostic Factors in Bronchial Arterial Embolization for Hemoptysis
Abstract
- PURPOSE
To find the rebleeding factors in bronchial arterial embolization for treatment of hemoptysis, a
retrospective study was performed.
MATERIALS AND METHODS
Medical records, anglographic findings and embolic materials of 35 patients who
had undertaken arterial embolization for control of hemoptysis were reviewed. The period of follow-up for
rebleeding was from 3 to 32 months after arterial embolization. We investigated the anglographic findings of
extravasation, neovascularity, intervascular shunt, aneurysm and periarterial diffusion. Neovascularity was
classified as mild(numerable neovascularity) and severe(innumerable).
RESULTS
Rebleeding occured in 15(43%) among 35 cases. Only two of 11 cases with no past episode of
hemoptysis showed recurrence, while 9 of 15 cases who had more than three episodes did. Severe
neovascularity were seen in 11 of 15 recurred cases, but seven of 20 non-recurred cases showed severe
neovascularity. More than three anglographic findings representing hemoptysis were seen on 11(73%) among
recurred 15 cases and seven(35%) among non-recurred 20 cases. The lesion was supplied by more than two
different arteries on 8(54%) of the recurred cases, but only three(15%) of the non-recurred cases. Six of seven
cases persistent neovascularity after arterial embolization were recurred.
CONCLUSION
The history of repeated hemoptysis, severe neovascularity, variable anglographic findings, and
post-embolization persistency of neovascularity were the factors related with the rebleeding after arterial
embolization for hemoptysis. Careful and active arterial embolization are required on these conditions.
