RESUMO
AIM: To evaluate the long-term clinical effectiveness of computed tomography (CT)-guided transforaminal cervical epidural steroid injection using an anterolateral approach for the treatment of cervical radiculopathy (CR) using well-established robust clinical scoring systems for neck pain and neck disability. Despite its widespread use, evidence to support the long-term benefit of routine cervical epidural steroid injection is currently very limited. MATERIALS AND METHODS: This study included 113 patients with magnetic resonance imaging (MRI)-confirmed CR who underwent a steroid injection at a single cervical level via a unilateral transforaminal anterolateral approach. Pain was assessed quantitatively at pre-injection, 15 minutes post-injection, 1 month, 3 months, and at 1 year. Neck disability was assessed using the Oswestry Neck Disability Index (NDI) at pre-injection, 1 month, 3 months, and 1 year time points. RESULTS: Eighty patients completed the study. Sixty per cent reported reduced neck pain (mean pain reduction, 55%), which was clinically significant in 45% cases. Furthermore, 66% reported an improvement in neck disability (mean improvement, 51%), which was clinically significant for 56% patients. Clinically significant good outcomes in both neck pain and neck disability were evident from as early as 1-month, and importantly, were independent both of pre-treatment CR characteristics (including severity of pre-injection neck pain or disability) and of findings on pre-injection MRI imaging. CONCLUSION: Transforaminal anterolateral approach CT-guided epidural steroid injection resulted in a clinically significant long-term improvement in both neck pain and disability for half of the present cohort of patients with unilateral single-level CR. This improvement was independent of the severity of the initial symptoms and pre-injection MRI findings.

AIM: To investigate the risk of endoleak during endovascular aneurysm repair (EVAR) involving the distal common iliac artery (CIA) when the internal iliac artery (IIA) is covered without prior coil embolization. MATERIALS AND METHODS: Retrospective analysis of 145 (125 men, 20 women) consecutive EVAR cases. Clinical notes and radiological images were reviewed, and data collected on patient demographics, aneurysm morphology, covering of the IIA with or without embolization, presence of endoleaks, and patient symptoms relating to IIA ischaemia. RESULTS: A total of 29 IIAs (10%) were covered in a total of 25 patients. Seven IIAs (24%) were embolized before stent covering (Embolization group), and 22 IIAs (76%) were covered only without embolization (Cover group). There was no statistically significant difference in the mean size of the abdominal aortic aneurysm diameter or CIA diameter between each group. No endoleaks from IIA retrograde filling were found in either group. CONCLUSION: The results of the present study do not support the traditional view that coverage of the IIA without prior embolization carries a high risk of endoleak, with no endoleaks seen in all 22 cases. Large-scale trials are required. However, the advent of branched-stenting techniques and the emergence of their success in long-term follow-up may preclude the former.
