Analysis of the risk factors for the development of post-operative spinal epidural haematoma.
ABSTRACT In order to identify the risk factors and the incidence of post-operative spinal epidural haematoma, we analysed the records of 14 932 patients undergoing spinal surgery between 1984 and 2002. Of these, 32 (0.2%) required re-operation within one week of the initial procedure and had an International Classification of Diseases (ICD)-9 code for haematoma complicating a procedure (998.12). As controls, we selected those who had undergone a procedure of equal complexity by the same surgeon but who had not developed this complication. Risks identified before operation were older than 60 years of age, the use of pre-operative non-steroidal anti-inflammatories and Rh-positive blood type. Those during the procedure were involvement of more than five operative levels, a haemoglobin < 10 g/dL, and blood loss > 1 L, and after operation an international normalised ratio > 2.0 within the first 48 hours. All these were identified as significant (p < 0.03). Well-controlled anticoagulation and the use of drains were not associated with an increased risk of post-operative spinal epidural haematoma.

ABSTRACT: We present a rare case of delayed onset of epidural hematoma after lumbar surgery whose only presenting symptom was vesicorectal disturbance. A 68-year-old man with degenerative spinal stenosis underwent lumbar decompression and instrumented posterolateral spine fusion. The day after his discharge following an unremarkable postoperative course, he presented to the emergency room complaining of difficulty in urination. An MRI revealed an epidural fluid collection causing compression of the thecal sac. The fluid was evacuated, revealing a postoperative hematoma. After removal of the hematoma, his symptoms disappeared immediately, and his urinary function completely recovered. Most reports have characterized postoperative epidural hematoma as occurring early after operation and accompanied with neurological deficits. But it can happen even two weeks after spinal surgery with no pain. Surgeons thus may need to follow up patients for at least a few weeks because some complications, such as epidural hematomas, could take that long to manifest themselves.Case reports in orthopedics. 01/2013; 2013:861961.

ABSTRACT: A 65-year-old man who had lateral cervical disc herniation underwent cervical posterior laminoforaminotomy at C5-6 and C6-7 level right side. During the operation, there was no serious surgical bleeding event. After operation, he complained persistent right shoulder pain and neck pain. Repeated magnetic resonance image (MRI) showed diffuse cervical epidural hematoma (EDH) extending from C5 to T1 level right side and spinal cord compression at C5-6-7 level. He underwent exploration. There was active bleeding at muscular layer. Muscular active bleeding was controlled and intramuscular hematoma was removed. The patient's symptom was reduced after second operation. Symptomatic postoperative spinal EDH requiring reoperation is rare. Meticulous bleeding control is important before wound closure. In addition, if patient presents persistent or aggravated pain after operation, rapid evaluation using MRI and second look operation is needed as soon as possible.Journal of Korean Neurosurgical Society 02/2013; 53(2):125-8. · 0.56 Impact Factor

ABSTRACT: Unaffected wound healing and good cosmetic result after a neurosurgical procedure are important factors measuring a level of care. The usefulness of high magnification of the operating microscope during closure of neurosurgical wounds is evaluated. During a one-year microneurosurgical fellowship, the first author (JK) performed wound closure under the microscope in 200 of 524 neurosurgical operations carried out by the senior author (JH) at the Department of Neurosurgery, Helsinki University Central Hospital. Supratentorial approaches were employed most frequently in 143 patients (72%). Surgeries for infratentorial lesions and the spinal canal comprised 48 (24%) and 9 procedures (4%), respectively. Mean duration of the surgery from skin to skin was 1.8 (range 0.5-6.2) hours. After intradural hemostasis was completed by the senior author, further steps including dural suturing, bone flap fixation, and wound closure were performed by the first author. Wound condition was assessed during the early and late postoperative period. Mean follow-up was 3.2 (range 1-10) months. Early postoperative healing of the wound was uneventful in 180 patients (90%). No wound rupture or postoperative hematoma occurred. In five patients (2.5%), lumbar puncture or spinal drainage was necessary due to significant subcutaneous liquor collection. No wound revision was required. At follow-up, in 196 patients (98%) the postoperative scar was in perfect condition. Neither skin necrosis nor healing problems occurred. Based on our results, we found the high magnification of operating microscope to be beneficial when closing neurosurgical wounds; it allows (1) better hemostasis, (2) precise wound margin approximation, (3) atraumatic handling of the tissues, and (4) improvement of the manual dexterity of the neurosurgeon.Surgical neurology international. 01/2013; 4:115.
