Lumbar subdural haematoma after temporomesial resection in epilepsy patients-report of two cases and review of the literature

Symptomatic Intracranial Hemorrhage after Dural Tear in Spinal Surgery-A Series of 10 Cases and Review of the Literature

OBJECTIVE

Intracranial hemorrhage (IH) after spinal surgery is a rare but potentially life-threatening complication. Knowledge of predisposing factors and typical clinical signs is essential for early recognition, helping to prevent an unfavorable outcome.

METHODS

A retrospective analysis was performed of patients with IH after spinal surgery treated in our institution between 2012 and 2018. The literature dealing with IH complicating spinal surgery was reviewed.

RESULTS

Our investigation found 10 patients with IH (6 female and 4 male). To the best of our knowledge, this is the largest series reported so far. The assumable incidence of IH after spinal surgery in our population was 0.0657%. Durotomy was noticed in 6 patients, all of whom were treated according to a local standard protocol. In 4 patients, the dural tear was occult. Hemorrhage occurred mostly in the cerebellar compartment. Eight of 10 patients had long-standing arterial hypertension, which seems to be a risk factor (hazard ratio, 1.58). Five patients were treated conservatively, whereas 3 required a cerebrospinal fluid (CSF) diversion procedure. In 2 patients, revision surgery with duraplasty was necessary. Seven patients were discharged with little to no neurologic symptoms, and 3 had significant deterioration. One patient died because of brainstem herniation. Review of the literature identified 54 articles with 72 patients with IH complicating spinal surgery.

CONCLUSIONS

Patients with intraoperative CSF loss should be kept under close supervision postoperatively. After opening of the dura, a watertight closure should be attempted. The use of subfascial suction drainage in cases of a dural tear as well as preexistent arterial hypertension seems to be a risk factor for the development of IH. Intracranial bleeding must be considered in every patient with unexplained neurologic deterioration after spinal surgery and should be ruled out by cranial imaging. To ensure early recognition and prevent an unfavorable outcome, a high index of suspicion is required, especially in revision spinal surgery. The treatment is specific to the extent and location of the IH, thus dictating the outcome. In most patients, conservative treatment led to a good outcome. CSF diversion measures may be necessary in patients with compression or obstruction of the fourth ventricle. Large hematomas with mass effect may require decompressive surgery.

Lumbosacral subdural hematoma associated with cranial subdural hematoma and craniocerebral surgery: Three cases and a systemic literature review

OBJECTIVE

The authors aim to focus on lumbosacral subdural hematoma (SDH) associated with cranial subdural hematoma and craniocerebral surgery, which has been rarely reported.

MATERIAL AND METHODS

They present 3 cases of lumbosacral SDH, including 2 associated with cranial chronic SDH and 1 following craniotomy for neck clipping of cerebral aneurysm. Using a PubMed search, they also provide a systemic literature review to summarize pathogenesis, treatment and outcome.

RESULTS

All cases presented with bilateral radiating leg pain, and recovered completely by conservative managements. Predisposing factors were trauma, anticoagulant therapy and brain atrophy. Literature review revealed 54 such cases, in which 28 cases associated with cranial SDH and 26 cases associated with craniocerebral surgery. In both group, main symptoms were low back and radiating leg pain, and sensorimotor deficits. Regardless of treatments, conservatively or surgically, outcome was favorable. Migration of cranial hematoma is most supported pathogenesis, while intracranial hypotension due to cerebrospinal fluid overdrainage procedures may also be a contributing factor for cases associated with craniocerebral surgery.

CONCLUSIONS

Lumbosacral SDH should be considered in patients present with unexpected low back and radiating leg pains associated with cranial SDH and craniocerebral surgery. Conservative treatment would be reasonable for cases with mild symptoms as the first treatment of choice.

Lumbar Subdural Hematoma Detected After Surgical Treatment of Chronic Intracranial Subdural Hematoma

BACKGROUND

Spinal subdural hematoma (SSDH), which can cause lower back pain, leg pain, and leg weakness, is rare and will usually be associated with a bleeding tendency, trauma, spinal vascular malformation, intraspinal tumor, or iatrogenic invasion. Only a few cases of SSDH after intracranial chronic subdural hematoma (CSDH) have been reported. We report a case of lumbar SSDH in the absence of predisposing factors after reoperation for recurrent intracranial CSDH, which improved with conservative treatment.

CASE DESCRIPTION

Approximately 1 month after falling, a 63-year-old woman was experiencing left hemiparesis and impaired orientation that was diagnosed as right intracranial CSDH using computed tomography. Surgical treatment of the CSDH led to immediate improvement of her symptoms. On postoperative day 29, the right CSDH had recurred with left hemiparesis, and successful reoperation relieved the symptoms within a few hours postoperatively. However, 1 day after the second operation, very small acute subdural hematomas in regions along the left tentorium cerebelli and left falx cerebri were found on computed tomography. On day 31, she complained of sitting-induced bilateral radiating lower limb pain. Magnetic resonance imaging on day 34 showed an acute SSDH at the L4-L5 level and a sacral perineural cyst filled with hematoma, although her radiating pain was showing improvement. She was treated conservatively and was discharged without symptoms on day 44.

CONCLUSIONS

Although SSDH is rare, it is important for neurosurgeons and physicians to consider the possibility of a SSDH when lower limb pain or paresis occurs after procedures that will result in rapid intracranial pressure alterations such as drainage of an intracranial CSDH.

Temporal lobe resective surgery for medically intractable epilepsy: a review of complications and side effects

Object. It is widely accepted that temporal resective surgery represents an efficacious treatment option for patients with epilepsy of temporal origin. The meticulous knowledge of the potential complications, associated with temporal resective procedures, is of paramount importance. In our current study, we attempt to review the pertinent literature for summating the complications of temporal resective procedures for epilepsy. Method. A PubMed search was performed with the following terms: “behavioral,” “cognitive,” “complication,” “deficit,” “disorder,” “epilepsy,” “hemianopia,” “hemianopsia,” “hemorrhage,” “lobectomy,” “medial,” “memory,” “mesial,” “neurobehavioral,” “neurocognitive,” “neuropsychological,” “psychological,” “psychiatric,” “quadranopia,” “quadranopsia,” “resective,” “side effect,” “surgery,” “temporal,” “temporal lobe,” and “visual field.” Results. There were six pediatric, three mixed-population, and eleven adult surgical series examining the incidence rates of procedure-related complications. The reported mortality rates varied between 0% and 3.5%, although the vast majority of the published series reported no mortality. The cumulative morbidity rates ranged between 3.2% and 88%. Conclusions. Temporal resective surgery for epilepsy is a safe treatment modality. The reported morbidity rates demonstrate a wide variation. Accurate detection and frank reporting of any surgical, neurological, cognitive, and/or psychological complications are of paramount importance for maximizing the safety and improving the patients' overall outcome.
