2024年9月11日 · How pseudomeningoceles are treated depends on size, etiology and location. For example, early in the postoperative period spinal pseudomeningoceles can be treated with bed rest, introduction of a lumbar drain or targetted epidural blood patch 5.

Ninety percent of the surgeons manage spinal pseudomeningoceles nonoperatively for 7-14 days before re-exploration is considered. The most common steps taken to prevent pseudomeningoceles are watertight closure, tissue glues, and duroplasty.

A pseudomeningocele, or a collection of cerebrospinal fluid, typically presents as a postoperative complication, and can be asymptomatic and resolve spontaneously, though some present with headaches, low back pain, or radicular symptoms.

2016年9月8日 · The key to prevention of postoperative pseudomeningocele is a meticulous primary repair of dural tears detected intraoperatively. Fine suture material such as 5-0 or 6-0 monofilament, braided or coated synthetic is suitable, although leakage of CSF can occur through the needle holes in the dura.

We report four cases of postoperative large lumbar pseudomeningoceles that presented as asymptomatic soft fluctuant swelling over the back which resolved spontaneously.

Postoperative pseudomeningocele can result either from leakage of fluid through a surgical wound or from altered CSF dynamics. Normally, CSF circulating in the cranial vault lies underneath the duramater, skull, and myocutaneous tissue.

2024年12月31日 · Postoperative pseudomeningocele is a rare, but still existing, complication after spinal surgeries. It may be asymptomatic or presented with back pain, radicular pain or headaches. Many pseudomeningoceles resolve spontaneously, others require revision surgery with dural repair.

Symptomatic post-operative pseudomeningoceles or fistulae are rare complications of spine surgery. Clinically, patients may present with a variety of signs or symptoms ranging from recurrent radicular symptoms to wound drainage to a positional headache.

We came across two post-laminectomy patients with symptoms of low back pain, radicular pain and swelling over the operative site in past one year. An MRI scan was performed in these patients which revealed the presence of a pseudomeningocele at the site of previous surgery.

A postoperative pseudomeningocele is a collection of cerebrospinal fluid that, as a result of surgical alteration of the dura mater and the surrounding osseous structures or laminae, extends from the spinal canal into the adjacent paraspinal soft tissues.
