RESUMO
Transverse myelitis is an uncommon but well-defined neurological syndrome. However, a high index of suspicion is needed to diagnose this condition, especially when it occurs in concomitance with preexisting spinal canal stenosis. We report our patient, a 48 year old male, who initially presented to our spine clinic with acute onset unilateral lower limb weakness associated with urinary retention, which was suspected to be cauda equina syndrome due to a prolapsed intervertebral disc. However, initial magnetic resonance (MR) imaging showed only mild spinal canal stenosis from L2-L5 and C3- C6 levels; thus, the possibility of cauda equina syndrome was ruled out. A few days later, patient developed ipsilateral upper limb weakness giving an impression of hemiparesis due to stroke. However, imaging of brain returned normal. There was still a dilemma whether symptoms could be due to cervical myelopathy as there was mild cervical cord compression with early myelomalacia changes, but the findings were subtle to come to a definite conclusion. Subsequently, patient desaturated and required ventilatory support. Repeat MR imaging of the cervical spine revealed T2 hyperintensities spanning multiple levels in the cervical cord which highlighted the possibility of transverse myelitis and the diagnosis was clinched after a CSF analysis. Despite the debilitating effects, patient responded well to corticosteroid therapy and gradually recovered. This case is reported to highlight the diagnostic dilemma and the rapid progression of transverse myelitis that demands timely medical intervention to avoid permanent disabilities.
RESUMO
OBJECTIVE: Patients with venous leg ulcers (VLUs) represent the worse spectrum of chronic venous insufficiency (CVI). The Early Venous Reflux Ablation (EVRA) landmark trial published in 2018 demonstrated that early endovenous intervention results in faster healing of VLUs. We describe our post-EVRA experience using endovenous cyanoacrylate glue ablation (ECGA) to treat superficial venous reflux on an early basis and assess its efficacy and safety in the setting of VLUs. METHODS: There were 37 patients (39 legs, 43 truncal veins) with 43 discrete venous ulcers who underwent ECGA for CVI symptoms and VLUs. They received compression therapy and regular dressings for the VLUs postoperatively and were reviewed at 1 week, 3 months, 6 months, and 12 months after the procedure. Postoperative healing time for VLUs and complications were recorded along with the patient's satisfaction and postprocedure pain scores. RESULTS: The venous ulcers were all <30 cm2 before ECGA. The mean time for VLU healing from operation was 73.6 ± 21.9 days, and the primary occlusion rate of the CVI at both 1 week and 3 months was 100%. No major adverse events were observed except for one case of deep venous thrombosis. There was significant improvement in the revised Venous Clinical Severity Score postoperatively from 11 ± 1.63 (baseline) to 5.6 ± 1.37 (P < .001) at 3-month follow-up (on a scale of 0 to 27, with the severity of symptoms at a maximal 27). The visual analog scale scores for pain were low postoperatively, decreasing from a preoperative score of 6.84 ± 1.42 to 2.72 ± 1.59 (P < .001) at the 3-month follow-up (on a scale of 1-10, with 10 being the most severe pain). The median time to return to normal activities was 7 days (interquartile range, 5-7 days). CONCLUSIONS: ECGA together with compression therapy for VLUs is both safe and effective in this population of Asian patients. ECGA for patients with VLUs has excellent patient acceptability, minimal morbidity, and low recanalization rates at 12 months. Larger extensive studies and longer follow-up periods are required to validate the preliminary outcomes of this paper, and if it is proven to significantly improve ulcer healing rates, this will change the way we approach chronic venous ulceration.
