Fulltext Spontaneous Spinal Epidural Hematoma Associated With the Use of Low-dose Aspirin in Elderly Patient

Phang ZH, Chew JJ, A/P Thurairajasingam J, Ibrahim SB

Spontaneous spinal epidural hematoma is a rare condition defined by bleeding in the epidural space of the spine with no identifiable causes such as trauma, vascular malformation, or bleeding disorders. This is a case of a 79-year-old woman with a medical history of diabetes mellitus, dyslipidemia, and hypertension presented with the sudden onset of severe thoracolumbar back pain associated with weakness and numbness in her bilateral lower limb. Examination of the lower limb showed bilateral lower limb motor and sensory deficits. Laboratory investigations showed normal results. MRI showed posterior extradural intraspinal hematoma from T11 to L3 vertebrae. Patient underwent right hemilaminectomy and posterior decompression of T12 and L1 vertebrae to evacuate the hematoma. Postoperatively, her neurologic complications improved gradually. Decision was made not to restart aspirin. On follow-up at 1 year, the patient had complete recovery of neurologic complications of both lower limb and had no recurrence of bleeding. In short, this is a case of spontaneous spinal epidural hematoma associated with long-term use of low-dose aspirin in an elderly patient requiring surgical evacuation of hematoma with good functional outcome after the surgery. Therefore, aspirin should be prescribed cautiously especially to elderly patients.

Concurrent bariatric surgery and surgical resection of massive localized lymphedema of the thigh. A case report

Introduction: Massive localised lymphedema (MLL) is considered a rare large, pendulous localised benign overgrowth of lymphoproliferative tissue commonly seen in patients with morbid obesity. Histologically, it may be mistaken for well-differentiated liposarcoma; hence, it is also known as pseudosarcoma.
Presentation of case: We describe the successful management of MLL of the left medial thigh in a 35-year-old man weighing 220 kgs (BMI 80.8 kgs/m2). He underwent a concurrent laparoscopic sleeve gastrectomy with surgical resection of the MLL. He recovered well and during our last follow up six months after the operation, he is ambulating well and weighs 148 kgs (BMI 54.4 kgs/m2).
Discussion: MLL is a form of secondary lymphedema resulting in disruption or compression of normal lymphatic drainage due to fat accumulation in obese patients. Patients usually delay treatment for even up to a decade, when it becomes sufficiently large enough to restrict mobility and daily activities, or when it becomes infected. MLL is primarily a clinical diagnosis. A detailed history regarding its slow growth spanning over the years makes malignancy less likely. However, if left untreated, MLL may progress to angiosarcoma. Imaging studies such as computed tomography (CT) and a Magnetic Resonance Imaging (MRI) are usually performed to rule out malignancy or vascular malformations. A tissue biopsy is not recommended unless there are suspicious pigmented lesions.
Conclusion: MLL remains to be underdiagnosed. Due to the obesity epidemic, clinicians must be aware of this once rare disease. The role of concurrent bariatric surgery with surgical resection of MLL warrants further studies.

Fulltext Timing of Surgery and Surgical Strategies in Symptomatic Brainstem Cavernomas: Review of the Literature

Brainstem cavernomas (BSCs) are angiographically occult, benign low flow vascular malformations that pose a significant surgical challenge due to their eloquent location. The present study includes an extensive review of the literature and three illustrative cases of BSC with emphasis on the timing of surgery: surgical approaches, usage of intraoperative monitoring, and complication avoidance. A systematic search was performed using the PubMed database was from January 1, 1999, to June 2018. The relevant articles were reviewed with particular attention to hemorrhage rates, timing of surgery, indications for surgery, surgical approaches, and outcome. Along with this, a retrospective analysis of three cases of symptomatic BSC, who were operated for the same, during the year 2018 in our institute was conducted. All the three patients presented with at least 1 episode of hemorrhage before surgery. Of these, one patient was operated immediately due to altered sensorium whereas the other two were operated after at least 4 weeks of the hemorrhagic episode. The patients who were operated in the subacute phase of bleed were seen to have liquefaction of hematoma, thus providing a good surgical demarcation and thereby reduced surgery-related trauma to the surrounding eloquent structures. Two patients improved neurologically during the immediate postoperative period, whereas one had transient worsening of neurological deficits during the immediate postoperative period in the form of additional cranial nerve palsies which completely improved on follow-up after 2 months. Radical resection is recommended in all patients with symptomatic BSCs. Surgery should be considered after the first or the second episode of hemorrhage as multiple rebleeds can cause exacerbation of deficits and sometimes mortality as well. Considering surgical timing, anywhere between 4 and 6 weeks or the subacute phase of the hemorrhage is considered appropriate. The aims of surgical intervention must be to improve preoperative function, minimize surgical morbidity and to reduce hemorrhagic rates. In spite of the significant surgical morbidity associated with BSCs, appropriate patient selection, meticulous surgical planning with adjuncts such as intraoperative monitoring and neuronavigation will go a long way in avoidance of major postoperative complications.
