“…2 Pseudomenigocele can be congenital (nontraumatic) or traumatic. 3 4 The traumatic cause can be blunt trauma, inadvertent trauma to the dura, planned dural opening (surgery/ iatrogenic), infection, or intramural hemorrhage. 3 4 5 6 Following dural tear, if the arachnoid remains intact, a meningocele is then formed.…”

Ossification of pseudomeningocele is a rare occurrence and is one of the rare complications of ventriculoperitoneal (VP) shunt malfunction. We report a case of 12-year-old boy who came with features of raised intracranial pressure following shunt malfunction which was placed as a treatment to the aqueductal stenosis. Computed tomography showed ventriculomegaly and hypodense collection in the occiput with posterior rim of calcification. The findings were confirmed on histopathology. Although ossified pseudomeningocele is a rare entity following VP shunt placement, it should be suspected if patients present with aggravated symptoms, especially if there is shunt malfunction as the treatment option varies with the presence or absence of resultant symptoms and ossification.

“…S obzirom na to da se većina pseudomengokela spontano resorbira, jasno je da postoje čimbenici koji pridonose persistiranju nekih pseudomeningokela. Neke od predloženih teorija su: komunikacija sa subduralnim prostorom djeluje kao jednosmjerna valvula koja tijek likvora usmjerava prema pseudomeningokeli, hidrostatski tlak u uspravnom položaju i pulsirajući tijek likvora također bi usmjeravali likvor u pseudomeningokelu 16 . U konačnici se oko pseudomeningokele formira vezivna ovojnica s precipitiranim proteinima koja više nema sposobnost apsorpcije 16 .…”

Sažetak. Spinalni epiduralni prostor smješten je između dure mater i vertebralne kolumne i proteže se od foramen magnuma do nivoa S2/S3 spinalnog kanala. Podijeljen je u prednji i stražnji odjeljak. Zbog izvrsnog razlučivanja mekih tkiva, magnetska rezonancija metoda je izbora za otkrivanje i karakterizaciju patoloških promjena spinalnog epiduralnog prostora koje su etiološki različitog podrijetla. Mnoge lezije proizlaze iz samog epiduralnog prostora ili se šire iz okolnih struktura, a ovaj je prostor često sijelo metastatskih depozita. Zbog mogućnosti širenja patoloških procesa prema korijenima spinalnih živaca ili leđnoj moždini, lezije epiduralnog prostora mogu se prezentirati simptomima radikulopatije ili mijelopatije.Ključne riječi: epiduralni prostor; oslikavanje magnetskom rezonancijom; spinalni kanal Abstract. The spinal epidural space is located between the spinal dura mater and the vertebral column and extends from the foramen magnum to the sacral canal at the level of S2/S3. It is divided into anterior and posterior compartment. Due to its excellent soft tissue contrast magnetic resonance imaging is the gold standard for imaging and diagnosis of pathological processes of the spinal epidural space which differ in etiology. Many processes origin in the spinal epidural space or extend from adjacent structures and epidural space is a frequent location for metastatic processes. Due to the possibility of spreadingof the pathological processes along spinal nerves and the spinal cord, they may present with symptoms of radiculopathy or myelopathy.

“… 4 However, reoperations due to perioperative complications such as wound infections, epidural fibrosis, pseudomeningocele, or dural leak are also reported in the literature. 5 6 Reoperations after previously operated lumbar surgery tend to result in less favorable outcomes; 7 8 however, there are few reports published in the literature that specifically evaluated risk factors regarding reoperations after lumbar stenosis surgery. In this review, we aimed to evaluate the existing PubMed literature on revision surgeries following the primary procedure for lumbar canal stenosis.…”

In the current clinical scenario, restenosis following the primary surgical procedure for lumbar canal stenosis is being frequently noticed. A number of studies have evaluated the reoperation rates following different surgical procedures for lumbar canal stenosis. However, a dilemma still exists about the surgical procedures, associated comorbidities and reoperation rates. In this study, we have reviewed the existing literature for lumbar canal stenosis surgery and their reoperation rates. A PubMed search for all papers stating “reoperation after spinal stenosis,” “revision surgery after spinal stenosis,” and “reoperations and lumbar canal stenosis” were explored. A total of 440 publications were found, of which 23 publications were shortlisted. The existing literature on reoperation rates after surgery for lumbar canal stenosis was reviewed and analyzed. From the literature search, 29680 patients who underwent surgeries for spinal stenosis have been included in the review. 11.65% ± 4.25% of them underwent reoperations following the primary procedure with a followup period of 6.80 ± 3.90 years. Fenestration surgeries showed an average reoperation rate of 7.58% ± 5.29% in 8.28 ± 6.26 years followup as compared to laminectomy alone (12.70% ± 7.49%, 6.50 ± 2.12 years followup). Laminectomy with or without fusion showed a reoperation rate of 11.22% ± 4.25% in 6.00 ± 2.60 years followup period. The comparative results of these studies were however not significant. The causes of reoperation were multifactorial ranging from the type of procedure performed, associated comorbidities or smoking. Statistical data do not indicate the superiority of any particular type of surgery, which reduces the rate of reoperation. The causes for reoperation are inadequate decompression or instability. The literature does not give statistics for these complications in the papers. Smoking is an independent risk factor for revision surgery. Diabetes reduces the time interval between the initial surgery and the revision surgery. This review highlights the causes of reoperations in various lumbar stenosis surgeries, associated comorbidities and expected outcome.
