Treatment for Spontaneous Pneumothorax
Treatment for spontaneous pneumothorax depends on the severity of symptoms, the amount of breathing difficulty, whether the pneumothorax is primary or related to underlying lung disease, and whether the air leak resolves or continues. Some patients can be safely monitored while the lung gradually re-expands, while others require removal of air from the chest or surgery to stop an ongoing leak and reduce the risk of another pneumothorax.
At Providence Saint John’s Health Center, treatment is individualized according to the patient’s clinical condition and risk of recurrence.
How Is a Spontaneous Pneumothorax Treated?
The first goal of treatment is to make sure the patient is breathing safely and to allow the affected lung to re-expand. Modern treatment does not rely on pneumothorax size alone. Symptoms, oxygenation, underlying lung disease, clinical stability and the likelihood of continued air leakage all help determine whether observation or a procedure is appropriate.
Observation and Conservative Management
Selected patients with a primary spontaneous pneumothorax who have minimal symptoms and remain clinically stable may be managed without an immediate invasive procedure. The body can gradually absorb the air surrounding the lung while physicians monitor symptoms and lung expansion. This approach requires appropriate observation, reliable follow-up and clear instructions about when to seek urgent care if symptoms worsen.
Needle Aspiration
Needle aspiration removes air from the pleural space using a catheter or needle so the lung can re-expand. It can be an effective initial treatment for selected patients with primary spontaneous pneumothorax and may avoid the need for a chest tube. The patient is reassessed afterward to determine whether the lung remains expanded and whether additional treatment is necessary.
Chest Tube Drainage
A chest tube may be needed when a pneumothorax causes more significant symptoms, does not respond to other treatment, occurs in a patient with underlying lung disease or requires ongoing drainage. The tube is placed into the pleural space to remove air and allow the lung to expand while the source of the leak heals. The care team monitors the amount of air leakage and lung expansion to determine when the tube can safely be removed.
Ambulatory Treatment
Some patients with primary spontaneous pneumothorax may be treated using a small portable drainage device that allows them to leave the hospital while the lung continues to recover. Ambulatory treatment is appropriate only for carefully selected patients who are clinically stable and have access to experienced follow-up care.
What Is a Persistent Air Leak?
Most spontaneous pneumothoraces improve as the small opening that allowed air to escape from the lung seals. In some patients, however, air continues to pass from the lung into the pleural space despite drainage. This is known as a persistent air leak and can prevent the lung from remaining fully expanded.
Persistent air leakage may lead the pulmonary and thoracic surgery team to consider additional treatment. The timing of intervention is individualized rather than based on a single fixed number of days. The patient’s underlying lung condition, degree of air leakage, ability of the lung to expand and overall health all influence the decision.
When Is Surgery Recommended for Spontaneous Pneumothorax?
Surgery is generally considered when the likelihood of another pneumothorax is substantial or when the current air leak does not resolve. The decision is made according to the patient’s history, lung condition, occupation, activity needs and personal priorities regarding recurrence prevention.
Reasons Surgery May Be Considered
Thoracic surgery may be recommended for patients with a persistent air leak, failure of the lung to remain expanded, recurrent pneumothorax on the same side or a pneumothorax that later occurs on the opposite side. Surgery may also be considered after an initial episode when preventing recurrence is particularly important, such as for selected patients whose occupations or activities make another pneumothorax especially hazardous.
Primary and Secondary Spontaneous Pneumothorax
Patients with secondary spontaneous pneumothorax have underlying lung disease and may tolerate even a relatively small pneumothorax poorly because their respiratory reserve is already limited. Treatment and recurrence-prevention decisions may therefore differ from those used for otherwise healthy patients with primary spontaneous pneumothorax. Pulmonologists and thoracic surgeons consider the underlying disease as part of the overall treatment strategy.
Minimally Invasive Surgery for Spontaneous Pneumothorax
When surgery is needed, it is commonly performed using video-assisted thoracic surgery (VATS), a minimally invasive approach that allows the thoracic surgeon to examine the lung and pleural space through small incisions. The goal is to identify and treat the area responsible for air leakage and reduce the likelihood that another pneumothorax will occur.
Blebs, Bullae and Wedge Resection
Small weakened areas near the surface of the lung, known as blebs or bullae, can rupture and allow air to escape into the pleural space. During surgery, visible abnormal areas that are believed to be responsible for the leak may be removed using a limited wedge resection. Removing the suspected source of leakage helps the lung remain expanded.
Pleurodesis
Pleurodesis is a treatment designed to reduce the space in which another pneumothorax could develop by encouraging the lung and inner chest wall to adhere to one another as healing occurs. It can be performed surgically by mechanically irritating the pleural surface or, in selected situations, by introducing a medication through a chest tube to create a similar healing response.
Pleurodesis may be used alone in selected patients or combined with treatment of blebs or bullae. The approach depends on the cause of the pneumothorax, recurrence risk, surgical candidacy and the individual treatment plan.
Treatment for Recurrent Spontaneous Pneumothorax
A previous spontaneous pneumothorax increases the possibility of another episode, although recurrence risk differs substantially among patients. When pneumothorax recurs, treatment planning focuses not only on re-expanding the lung but also on reducing the chance that the problem will happen again.
Patients with a second pneumothorax on the same side or a first episode on the opposite side are commonly evaluated for definitive recurrence-prevention treatment. VATS with treatment of abnormal lung tissue and pleurodesis is one approach that may be recommended. Decisions are individualized according to the patient’s lung health, previous treatment and personal circumstances.
Catamenial Pneumothorax
Catamenial pneumothorax is a form of recurrent spontaneous pneumothorax associated with the menstrual cycle and thoracic endometriosis. Episodes most often occur close to the beginning of menstruation and are usually right-sided. Because the relationship may not be recognized immediately, recurrent pneumothorax in a woman of reproductive age should prompt careful review of the timing of symptoms in relation to the menstrual cycle.
Treatment may require a combination of thoracic surgery and hormonal management. During surgery, the thoracic surgeon can examine the lung, pleural surfaces and diaphragm for areas of endometriosis, abnormal openings or other findings that may contribute to recurrence. Treatment can include removal of visible disease, repair of diaphragm abnormalities and pleurodesis, with gynecologic or hormonal treatment considered as part of coordinated care.

What to Expect After Pneumothorax Treatment
Recovery depends on whether treatment involved observation, aspiration, chest drainage or surgery. Patients treated without surgery are followed to confirm that the lung continues to expand and symptoms improve. After VATS, recovery generally includes pain control, walking, breathing exercises and monitoring of the chest tube until air leakage has stopped and the lung remains expanded.
Patients receive guidance about gradually returning to normal activity and about situations that can be affected by changes in atmospheric pressure. Air travel is generally postponed until the pneumothorax has completely resolved and a physician confirms that flying is safe. Scuba diving carries substantially different risks after spontaneous pneumothorax and should be discussed specifically with a physician familiar with the patient’s history.
Reducing the Risk of Another Pneumothorax
Not every recurrence can be prevented, but addressing modifiable risk factors and choosing recurrence-prevention treatment when appropriate can reduce risk. Smoking cessation is particularly important because cigarette smoking is strongly associated with spontaneous pneumothorax and recurrence. Patients with underlying lung disease should also continue appropriate treatment to protect their remaining respiratory function.
For patients at higher risk of recurrence, surgery and pleurodesis may provide a more durable solution by treating the suspected source of air leakage and reducing the ability of air to collect again in the pleural space. The expected benefit must be balanced against the risks of intervention and the individual patient’s goals.
Advanced Thoracic Care for Spontaneous Pneumothorax
At Providence Saint John’s Health Center, pulmonologists and thoracic surgeons work together to determine the most appropriate treatment for spontaneous pneumothorax, from careful observation and minimally invasive drainage to advanced thoracic surgery. Treatment decisions consider not only the immediate pneumothorax but also underlying lung disease, persistent air leakage and the patient’s long-term risk of recurrence.
When surgical treatment is appropriate, minimally invasive thoracic techniques can be used to identify and treat areas of air leakage and perform recurrence-prevention procedures. The goal is to safely re-expand the lung, restore breathing and activity, and reduce the likelihood of another pneumothorax whenever possible.
