RESUMO

Background: Postoperative hydrocephalus and subdural fluid collection (SFC) have been reported as the rare complications following foramen magnum decompression in patients with Chiari malformation.Case Description: The paper reports the case of a 63-year-old female patient who underwent foramen magnum decompression for basilar invagination. The patient developed a shifting, bilateral SFC and subsequent acute hydrocephalus. A ventriculoperitoneal shunting was performed and the clinical symptom resolved. The dramatic change in CSF distribution supported the diagnosis of external hydrocephalus, which was associated with a postoperative cervical pseudomeningocele.Conclusions: Postoperative SFC in patients underwent foramen magnum decompression may harbor different mechanisms. Subdural drainage for patients having external hydrocephalus may have a higher recurrence rate.

RESUMO

BACKGROUND: Spontaneous intracerebral hemorrhage (SICH) is of high mortality and morbidity. SICH in the basal ganglia is usually attributed to chronic hypertension. Postoperative rehemorrhage is a severe complication, and it is relative to surgical techniques. METHODS: A retrospective survey was conducted on 123 patients with basal ganglia SICH who received surgery from January 2015 to January 2019. Postoperative rehemorrhage within 24 hours was recorded. Preoperative clinical parameters, surgeon experience (<10 and >20 years), operation time, surgical approach, and hemostasis technique were recorded and analyzed. RESULTS: The total postoperative rehemorrhage rate was 12.2% (15/123). The univariable analysis showed general surgeons had a higher postoperative rehemorrhage rate than experienced surgeons (30.4% vs. 8.6%, respectively; P = 0.068). The operation time (minutes) in experienced surgeons was significantly longer (164.9 ± 53.5 vs. 137.7 ± 30.8, P = 0.016), but they had a higher chance to locate the responsible vessel (74.2% vs. 40.0%, P = 0.001), respectively. Logistic analysis indicated that experienced surgeons significantly reduced the risk of rehemorrhage (odds ratio [OR], 0.242; P = 0.021). Transsylvian approach was a protective factor for postoperative rehemorrhage (OR, 0.291; P = 0.045). CONCLUSIONS: Surgeons' experience plays the most important role in postoperative rehemorrhage. Surgeons with rich experience were willing to spend more time to achieve definitive hemostasis in operation. The use of a transsylvian approach can significantly reduce the rehemorrhage rate. Packing hemostasis with gelatin sponge may increase complications.

RESUMO

BACKGROUND: Hydrocephalus is a common complication following decompressive craniectomy. Ventriculoperitoneal shunt (VPS) is required for some patients before receiving a cranioplasty (CP). The presence of a VPS is regarded as a risk factor for overall CP complications. METHODS: A retrospective survey was conducted on 176 patients with traumatic brain injury who underwent late (>3 months) titanium CP (Ti-CP) in our hospital from April 2014 to July 2018. Thirteen patients (7.4%) had preoperative VPS. Propensity score matching was performed for these 13 patients with a ratio of 1:5. A total of 78 patients were selected. Preoperative clinical parameters and postoperative complications were analyzed. The period of postoperative follow-up ranged from 3 to 63 months (mean 21.3 ± 17.0 months). RESULTS: The overall complication rate was greater in the VPS group (P = 0.010). These patients were more likely to develop a sunken skin flap (P < 0.001). The rate of postoperative cerebral hemorrhage was greater in the VPS group. Logistic analysis showed that preoperative VPS was an independent risk factor for postoperative extradural collection (odds ratio 17.714, P < 0.001). VPS was not related to postoperative infection and seizure. Postoperative drainage duration longer than 2.5 days significantly increased the risk of postoperative infection (odds ratio 7.715, P = 0.023). CONCLUSIONS: The presence of a VPS significantly increased the risk of extradural collection in patients with traumatic brain injury who underwent late Ti-CP. It also was related to postoperative hemorrhage. The sunken skin flap in patients with VPS increased surgical difficulty and the likelihood of extradural accumulation. Preoperative VPS was not related to postoperative infection and seizure in Ti-CP.

RESUMO

BACKGROUND: Cranioplasty is a routine procedure, but it carries a significantly higher complication rate over standard clean cranial surgery. Surgical site infection is the most common but severe complication. Risk factors for surgical site infection are still debated. METHODS: A retrospective survey of 155 patients (≥16 years old) who exclusively underwent customized titanium cranioplasty from April 2014 to January 2017 was performed. Preoperative clinical parameters, surgeon's hemostasis technique, temporalis dissection, operative time, intraoperative blood loss, postoperative catheter duration and drainage, postoperative hemorrhage and extradural fluid collection (EDFC), and prophylactic antibiotics were recorded and compared between patients with superficial surgical site infection (sSSI) and patients with non-sSSI. RESULTS: Overall sSSI rate was 10.3%. Binary logistic analysis showed excessive hemostasis on scalp (odds ratio = 10.302, P = 0.000), presence of postoperative EDFC (odds ratio = 12.740, P = 0.003), and postoperative drainage >277 mL (odds ratio = 10.302, P = 0.000) were independent risk factors for sSSI. Patients who received excessive hemostasis had a longer operative time (P = 0.000). A flaccid cranial defect was a protective factor for postoperative EDFC (odds ratio = 0.130, P = 0.044), whereas presence of ventriculoperitoneal shunt could induce EDFC formation (odds ratio = 9.598, P = 0.020). Postoperative subgaleal drainage was correlated to the size of cranial defect (standardized ß = 0.347, P = 0.000). Timing of cranioplasty and use of prophylactic antibiotics were not related to sSSI. CONCLUSIONS: Surgeons should lower the hemostasis standard for cranioplasty, as this would promote wound healing and reduce operative time, which subsequently decreases SSI rate.

RESUMO

BACKGROUND: Ventriculostomy-associated cerebrospinal fluid infection (VAI) is a major complication limiting the use of an external ventricular drain (EVD) in treating patients with intraventricular hemorrhage (IVH). Risk factors of VAI are still under wide discussion. METHODS: We performed a retrospective review of 84 patients with IVH who underwent EVD at our center between January 2012 and January 2017. Preoperative clinical parameters, surgeon status, number of catheters and catheter-days, subgaleal tunneling distance, frequency of urokinase flush, and prophylactic antibiotics were compared between the infective and noninfective groups. RESULTS: The overall rate of VAI was 31.0%. Univariate analysis showed a higher modified Graeb Score (mGS), higher proportion of bilateral catheters, and longer hospital stay in patients with VAI. Binary logistic analysis of all clinical factors identified high mGS (≥16) as an independent risk factor for VAI (odds ratio, 3.242; P = 0.026). Among operative and postoperative factors, the use of bilateral catheters significantly contributed to VAI (odds ratio, 4.211; P = 0.031), but a subgroup comparison showed an increased VAI rate only in the low mGS group (mGS <15). No VAI occurred in patients with a single EVD in the low mGS group. Catheter-days and multiple urokinase flushes were not related to VAI. CONCLUSIONS: Patients with a high mGS are vulnerable to VAI. Bilateral EVD may be an appropriate treatment option for patients with a high mGS, but might increase the risk of infection in those with a low mGS.

RESUMO

Neuroendoscopic endonasal approach has gained popularity in managing traumatic, spontaneous, and especially iatrogenic cerebrospinal fluid (CSF) rhinorrhea. The authors examined 8 patients presenting with CSF rhinorrhea between December 2012 and June 2014: 5 patients had iatrogenic leak, 2 patients had traumatic leak, and 1 patient had a spontaneous onset of CSF rhinorrhea. Sites of the CSF leaks were detected through computed tomographic cisternography and magnetic resonance imaging in the patients with traumatic and spontaneous leaks. All patients received neuroendoscopic endonasal surgery for the CSF leak. The largest defect was 22 mm in maximum diameter. Endoscopic supraciliary "keyhole" approach was performed in 1 patient after confirmation of a frontal sinus leak using the endoscopic endonasal approach. The success rate was 100% in the first attempt. Follow-up period ranged from 3 to 24 months, and no recurrence was reported. Identifying the leak site and choosing the appropriate surgical technique remain the most important factor in surgical success.
