Posterior mediasten yerleşimli nörojenik tümörlerde spinal kanal invazyon insidansı ve cerrahi yaklaşımı
Öz
Amaç: Posterior mediastinal nörojenik tümörlerin yaklaşık %10’u spinal kanala
invazedir. İnvaze tümörlerin tek seansta güvenli bir şekilde spinal ve torasik
komponentinin birlikte çıkarılması gerekir. Bu lokalizasyondaki tümörlerin
spinal kanal invazyonunun olup olmadığının direkt ve indirekt bulguları,
ameliyat öncesi çektirilen bilgisayarlı tomografi (BT) ve manyetik rezonans
görüntülemesi (MRI) ile detaylı olarak değerlendirilmelidir. Çalışmamızda,
kliniğimizde opere ettiğimiz bu tür tümörlerdeki tanı ve yaklaşımımızın
sunulması amaçlanmıştır.
Gereç ve Yöntem: Nörojenik tümör nedeni
ile opere ettiğimiz tüm hastaların klinik bilgileri retrospektif olarak analiz
edildi.
Bulgular: Çalışmaya aldığımız 35 hastanın
19’u erkek 16’sı kadındı ve yaş ortalaması 40 yıldı (dağılım: 19-71). Hastaların
sadece 5’inde (%14) operasyon öncesi semptom mevcuttu. Tümör boyutları 2,1 cm ile 17 cm arasında (ortanca 6,2)
idi. Hastaların 7’sinde (%20) radyolojik olarak spinal kanal invazyonu olduğu
belirtildi. Laminektomi gerektiren dumbbell
tipteki 6 hasta ile birlikte hepsi komplet olarak rezeke edildi. İnvazyon
gösteren vakalardaki lezyonlar beyin ve sinir cerrahi uzmanı ile birlikte
yapıldı. Ortalama takip süresi 48 ay (3 ila 72 ay) idi. Bir hastada ameliyat
sırasında tamir edilen serebrospinal sıvı kaçağı ile postoperatif kalıcı
olmayan spinal hasar meydana geldi ve 4 ayda düzeldi. Mortalite gözlenmedi.
Sonuç: Ameliyat öncesinde, nörojenik dumbbell tümör teşhis edilmezse, sadece
intratorasik kısmının çıkarılması, kalıcı spinal hasara neden olabilir. Spinal kanalı
incelemek için MRI kritik öneme sahiptir. Preoperatif invazyon tespit
edildiğinde tek seansta sinir cerrahisi ekibi ile birlikte tümörün daha güvenli
rezeksiyonu mümkündür.

Spinal canal invasion incidence and surgical approach to the neurogenic tumors of the posterior mediastinum
Öz
Aim: Approximately 10% of posterior mediastinal neurogenic tumors invade the
spinal canal. Safe removal of these tumors requires single-stage combined
neurosurgical and thoracic operations. Meticulous radiological preoperative
examination with computed tomography (CT) and magnetic resonance imaging (MRI)
is obligatory for assessing direct or indirect signs of spinal canal
involvement. Hereby, we reviewed our clinical experience of preoperative
diagnostic and therapeutic approaches in these types of tumors.
Materials and Methods: Clinical files of all patients undergoing surgical
resection at our institution for a neurogenic tumor located at the posterior
mediastinum were reviewed retrospectively.
Results: The mean age of the 35 patients was 40 years (range 19-71), including 19
males and 16 females. Preoperative
symptoms were present in five patients (14%). Tumor
size was ranging from 2.5 to 17 cm (median 6.2). Preoperative radiological
examination revealed spinal canal involvement in seven (20%) patients. All
patients were performed complete resection, including an additional laminectomy
in six cases of dumbbell-type. Intraforaminal portion was resected by the
neurosurgeon. Mean follow-up period was 48 (range 3-72) months. Major
complication of postoperative cerebrospinal fluid leakage, detected and treated
intraoperatively, with non-permanent spinal cord injury was seen in 1 patient,
fully recovered in 4 months postoperatively. No mortality occurred.
Conclusion: If a dumbbell neurogenic tumor is not recognized and only the
intrathoracic portion is resected, it may cause permanent spinal cord injury
and neurological problems. Spinal MRI is crucial to examine the spinal canal. If
spinal canal invasion is detected preoperatively, a single-stage and safe
resection with neurosurgical team may be possible.
