On-ward surgical management of wound dehiscence: report of a single neurosurgical center experience and comparison of safety and effectiveness with conventional treatment.

The early identification and optimized treatment of wound dehiscence are a complex issue, with implications on the patient's clinical and psychological postoperative recovery and on healthcare system costs. The most widely accepted treatment is surgical debridement (also called "wash out"), performed in theater under general anesthesia (GA), followed by either wide-spectrum or targeted antibiotic therapy. Although usually effective, in some cases, such a strategy may be insufficient (generally ill, aged, or immunocompromised patients; poor tissue conditions). Moreover, open revision may still fail, requiring further surgery and, therefore, increasing patients' discomfort. Our objective was to compare the effectiveness, costs, and patients' satisfaction of conventional surgical revision with those of bedside wound dehiscence repair. In 8 years' time, we performed wound debridement in 130 patients. Two groups of patients were identified. Group A (66 subjects) underwent conventional revision under GA in theater; group B (64 cases) was treated under local anesthesia in a protected environment on the ward given their absolute refusal to receive further surgery under GA. Several variables-including length and costs of hospital stay, antibiotic treatment modalities, and success and resurgery rates-were compared. Permanent wound healing was observed within 2 weeks in 59 and 55 patients in groups A and B, respectively. Significantly reduced costs, shorter antibiotic courses, and similar success rates and satisfaction levels were observed in group B compared with group A. In our experience, the bedside treatment of wound dehiscence proved to be safe, effective, and well-tolerated.

Clinical Outcome of Patients Over 90 Years of Age Treated for Chronic Subdural Hematoma.

OBJECTIVE: Chronic subdural hematoma (CSDH) is one of the most common pathology in daily neurosurgical practice and incidence increases with age. The aim of this study was to evaluate the prognostic factors and surgical outcome of CSDH in patients aging over 90 years compared with a control group of patients aging under 90 years. METHODS: This study reviewed 25 patients with CSDH aged over 90 years of age treated in our department. This group was compared with a younger group of 25 patients aged below their eighties. At admission past medical history was recorded concerning comorbidities (hypertension, dementia, ictus cerebri, diabetes, and heart failure or attack). History of alcohol abuse, anticoagulant and antiplatelet therapy, head trauma and seizures were analyzed. Standard neurological examination and Markwalder score at admission, 48 hours after surgery and 1-6 months follow-up, radiologic data including location and CSDH maximum thickness were also evaluated. RESULTS: Their mean age was 92.8 years and the median was 92.4 years (range, 90-100 years). In older group, the Markwalder evaluation at one month documented the complete recovery of 24 patients out of 25 without statistical difference with the younger group. This data was confirmed at 6-month follow-up. One patient died from cardiovascular failure 20 days after surgery. The presence of comorbidities, risk factors (antiplatelet therapy, anticoagulant therapy, history of alcohol abuse, and head trauma), preoperative symptoms, mono or bilateral CSDH, maximum thickness of hematoma, surgical time and recurrence were similar and statistically not significant in both groups. CONCLUSION: In this study, we demonstrate that surgery for very old patients above 90 years of age affected by CSDH is safe and allows complete recovery. Comparing two groups of patients above and under 90 years old we found that complication rate and recovery were similar in both groups.

Surgical treatment and outcome in patients over 80 years old with intracranial meningioma.

OBJECTIVE: Study of mortality rate and clinical outcomes in octogenarians patients operated for intracranial meningiomas. PATIENTS AND METHODS: Clinical, radiological and surgical data of 25 elderly patients aging over 80 years old operated at our Department from 2013 to 2016 for intracranial meningiomas have been recorded and analyzed. One-month mortality and clinical outcome at six-months after surgery were evaluated. Logistic regression was used for detecting the risk factors influencing mortality and neurological functions. RESULTS: The median age at diagnosis was 8185 years (range 80-87). Meningiomas were gross-total removed in 18 cases out of 25 (72%) and partially resected in 7 (28%). One-month post-operative mortality occurred in 2 pts out of 25 (8%). A close correlation was found between operative duration over 240 min and mortality (p = 0,0421). There was a significantly lower mortality in patients with ASA II rather than in patients with ASA III (p = 0,038). The median pre-operative KPS value was 743 (range 50-90) while at six-month follow-up was 82. The surgical time (p = 00,006) and size of the lesion >4 cm (p = 002) were a significant prognostic factors for clinical improvement at six-month follow-up. CONCLUSIONS: The operative time and the ASA score are the most important prognostic factors for the mortality and neurological outcome of elderly patients over 80 years old operated for intracranial meningioma. Even if the number of patients is limited, our findings suggest that, after a careful preoperative stratification in elderly patients, it is possible to remove an intracranial meningioma with good results.

Penile Mondor's disease after anterolateral retroperitoneal approach for lumbar fracture.

This is a rare case of thrombosis of the dorsal vein of the penis (Mondor's disease) occurred after an anterior-lateral retroperitoneal approach for a vertebral stabilisation in thoracolumbar vertebral fracture. Potential causes are traumatism, neoplasms, excessive sexual activity or abstinence. Although penile Mondor's disease is a clinical diagnosis, ultrasound imaging is the gold standard to confirm it. In the reported case, 1 week after neurosurgical retroperitoneal procedure of vertebral stabilisation, the patient complained of a painful cord-like mass midshaft of penis. The diagnosis was made by clinical evaluation and ultrasound images. After 2 weeks of therapy with enoxaparin sodium, the patient recovered. The authors report this case evaluating the possible correlation between the anterior-lateral retroperitoneal approach and the development of the rare Mondor's disease.

Microsurgical endoscopy-assisted anterior corpus callosotomy for drug-resistant epilepsy in an adult unresponsive to vagus nerve stimulation.

Because most of the corpus callosotomy (CC) series available in literature were published before the advent of vagus nerve stimulation (VNS), the efficacy of CC in patients with inadequate response to VNS remains unclear, especially in adult patients. We present the case of a 21-year-old female with medically refractory drop attacks that began at the age of 8 years, which resulted in the patient being progressively unresponsive to vagus nerve stimulation implanted at the age of 14 years. Corpus callosotomy was recommended to reduce the number of drop attacks. However, the patient had only mild cognitive impairments and no neurological deficits. For this reason, we were forced to plan a surgical approach able to maximize the disconnection for good seizure control while, at the same time, minimizing sequelae from disconnection syndromes and neurosurgical complications because in such cases of long-lasting epilepsy the gyri cinguli and the arteries can be tenaciously adherent and dislocated with all the normal anatomy altered. In this scenario, we opted for a microsurgical endoscopy-assisted anterior two-thirds corpus callosotomy. The endoscopic minimally invasive approach proved to be quite adequate in this technically demanding case and confirmed that CC may offer advantages, with good results, even in adult patients with drop attacks who have had inadequate response to VNS.

Posterior Titanium Screw Fixation without Debridement of Infected Tissue for the Treatment of Thoracolumbar Spontaneous Pyogenic Spondylodiscitis.

STUDY DESIGN: Retrospective study. PURPOSE: The aim of our study was to analyze the safety and effectiveness of posterior pedicle screw fixation for treatment of pyogenic spondylodiscitis (PSD) without formal debridement of the infected tissue. OVERVIEW OF LITERATURE: Posterior titanium screw fixation without formal debridement of the infected tissue and anterior column reconstruction for the treatment of PSD is still controversial. METHODS: From March 2008 to June 2013, 18 patients with PSD underwent posterior titanium fixation with or without decompression, according to their neurological deficit. Postero-lateral fusion with allograft transplantation alone or bone graft with both the allogenic bone and the autologous bone was also performed. The outcome was assessed using the visual analogue scale (VAS) for pain and the Frankel grading system for neurological status. Normalization both of C-reactive protein (CRP) and erythrocyte sedimentation rate was adopted as criterion for discontinuation of antibiotic therapy and infection healing. Segmental instability and fusion were also analyzed. RESULTS: At the mean follow-up time of 30.16 months (range, 24-53 months), resolution of spinal infection was achieved in all patients. The mean CRP before surgery was 14.32±7.9 mg/dL, and at the final follow-up, the mean CRP decreased to 0.5±0.33 mg/dL (p <0.005). Follow-up computed tomography scan at 12 months after surgery revealed solid fusion in all patients. The VAS before surgery was 9.16±1.29 and at the final follow-up, it improved to 1.38±2.03, which was statistically significant (p <0.05). Eleven patients out of eighteen (61.11%) with initial neurological impairment had an average improvement of 1.27 grades at the final follow-up documented with the Frankel grading system. CONCLUSIONS: Posterior screw fixation with titanium instrumentation was safe and effective in terms of stability and restoration of neurological impairment. Fixation also rapidly reduced back pain.
