Lung 2010-05-17 .txt text/plain 12865 674 35 Unlike the situation with heart transplant recipients, chronic vascular rejection in lung transplants has not resulted in graft loss; however, some patients develop pulmonary hypertension particularly those with BOS [92, 111] . However, based on the link between acute rejection and development of BOS, surveillance transbronchial biopsies in asymptomatic lung transplant recipients has become common practice in many large lung transplantation centers because evidence suggests that patients who have multiple episodes of low grade (A1) lesions within the first 12 months posttransplantation develop early onset BOS. A study [49] in which surveillance transbronchial biopsies were performed at 3, 6, 9, and 12 weeks posttransplantation, at the time of symptoms, and for follow-up of acute rejection or CMV pneumonia showed that patients who develop acute small airways rejection within the first year after transplantation are at risk of development of BOS at 1.76, 3.3, and 5.5 years after detection of B3/ B4 lesion (by 1996 ISHLT criteria, see Table 7 .2), B2 lesion or B0/B1 lesion, respectively. ./cache/cord-016235-2lhrkmrv.txt ./txt/cord-016235-2lhrkmrv.txt
