Perioperative Mortalität

Die chirurgische Lungenvolumenreduktion (LVR) ist ein neuartiges operatives Behandlungskonzept für ausgewählte Patienten mit fortgeschrittenem Lungenemphysem, die trotz optimaler Therapie schon bei geringer Anstrengung an Atemnot leiden und funktionell erheblich eingeschränkt sind. Mittels beidseitiger videoassistierter thorakoskopischer Resektion werden die am meisten vom Emphysem betroffenen Lungenabschnitte reseziert. Dadurch wird die stark überblähte Lunge verkleinert und die Atemmechanik verbessert. Dieses Verfahren, das an spezialisierten Zentren eine überraschend geringe perioperative Mortalität und Morbidität hat, führt bei der Mehrheit der operierten Patienten zu einer deutlichen symptomatischen Verbesserung, die durch eine Besserung der Lungenfunktion und der körperlichen Belastbarkeit bedingt ist. Die maximale funktionelle Verbesserung wird innert drei Monaten nach der Operation erreicht und nimmt nach ein bis zwei Jahren langsam ab.

BackgroundThe key issues for performing lung volume reduction surgery (LVRS) is the identification of the target zones. Recently introduced three-dimensional computed tomography rendering methods are used to identify the morphological distribution and its severity of lung emphysema by densitometry. We demonstrate a new software for emphysema imaging and show the pre- and post-operative results in patients undergoing LVRS planned based on this new technology.MethodsA real-time three-dimensional image analysis software system was used pre- and 3 months post-operatively in five patients with heterogeneous emphysema and a single patient with homogeneous morphology scheduled for LVRS. Focus was on low attenuation areas with <950 HU, distribution on both lungs and the value of the three-dimensional images for planning surgery. Functional outcome was assessed by pulmonary function tests after 3 months.ResultsFive patients underwent bilateral LVRS and one patient had unilateral LVRS. All patients showed a median increase in forced expiratory volume in 1 s of 70% (range 30–120%), compared with baseline values. Hyperinflation (expressed as residual volume/total lung capacity ratio) was reduced by 30% (range 5–32%). In the patients with heterogeneous emphysema, the pre- and post-operative computed tomography scans and the densitometries showed a decrease in low attenuation areas by 23% (right side) and by 17% (left side), respectively.ConclusionWe demonstrate three-dimensional computed tomography-rendered images for planning personalised remodelling of hyperinflated lungs using LVRS. This user-friendly software has the potential to assist surgeons and interventional pulmonologists to select patients and to visualise target areas in LVRS procedures.
