Zusammenfassung
Die spinale Ischämie ist ein Problem in der thorakoabdominalen Aortenchirurgie. In der Folge entwickeln sich neurologische Ausfälle wie sensorische Defizite, aber auch Paraparesen und Paraplegien. Deshalb bleibt die Protektion des Rückenmarks während thorakoabdominaler Aortenrekonstruktionen eine wichtige Aufgabe. Das am häufigsten verwendete neurologische Monitoring ist die Messung des Liquordrucks im lumbalen Spinalkanal und die spinale Flüssigkeitsdrainage. Klinische oder technische Komplikationen wie Meningitiden oder Katheterbrüche sind nicht selten durch die häufigen und intermittierenden Liquorentnahmen am Tropfkammersystem bedingt. Weitere Komplikationen sind intraspinale Hämatome und intrakranielle subdurale Hämatome bei exzessiver manueller Drainage. Bei den bisher durchgeführten Lumbaldrainagen handelte es sich um manuell durchgeführte unregelmäßige Drainagen. Unter Einbindung des LiquoGuards der Firma Möller Medical GmbH konnte erstmals ein kontinuierlicher druckgesteuerter Liquorabfluss ermöglicht werden. Ferner handelt es sich im Gegensatz zu den bekannten Tropfkammersystemen um ein geschlossenes steriles Drainageverfahren.
Abstract
Spinal ischemia is an unresolved problem in thoracoabdominal surgery of the aorta. As a result, neurological failures such as sensory deficits occur, as well as paraparesis and paraplegia. Therefore, protection of the spinal cord during thoracoabdominal surgery is a major challenge. The most commonly used method of neurologic surveillance is measurement of spinal fluid drainage and cerebrospinal pressure in the lumbar spinal canal. Complications such as meningitis or spinal catheter fracture can be caused by intermittent fluid withdrawal in the drop-chamber system. Further complications include intraspinal hematoma and intracranial subdural hematoma due to excessive manual drainage. So far, cerebrospinal fluid drainage systems have been manual and unbalanced. Using LiquoGuard (Möller Medical), continuous pressure-controlled cerebrospinal fluid drainage has been enabled for the first time. Furthermore, this drainage system is closed and sterile, in contrast to established drop-chamber systems.
