The severity of pulmonary blisters in the lower lobe of the left lung needs to be judged in relation to the number and size of the blisters, as well as the symptoms of complications. Small, asymptomatic blisters can be left untreated, while larger blisters or those with complications require surgery.
Smaller and fewer lung blisters may not have any symptoms and are usually found incidentally during a chest X-ray or CT scan.
For larger or multiple lung blisters, they are prone to rupture and cause spontaneous pneumothorax and spontaneous hemopneumothorax, which can be life-threatening in serious cases. Larger pulmonary blisters can also compress adjacent lung tissue, causing patients to experience chest tightness, shortness of breath and other manifestations. Surgical resection of pulmonary herpes is often advocated for those with obvious symptoms.
Pulmonary herpes is an irreversible lung lesion, and it is recommended that patients be treated as soon as possible to avoid delaying the condition and affecting the prognosis.
