INTRODUCTION: Aneurysm regression and target vessel patency during early and mid-term follow-up may be related to the effect of stent graft configuration on the anatomy. We quantified geometry and remodeling of the renal arteries and aneurysm following fenestrated (F-) or snorkel/chimney (Sn-) endovascular aneurysm repair (EVAR). METHODS: 29 patients (mean age, 76.8±7.8 years) treated with F- or Sn-EVAR underwent computed tomography angiography at pre-op, post-op, and follow-up...

Subsidence of interbody cages is a frequently observed and relevant complication in anterior cervical discectomy and fusion (ACDF). Only a handful of studies concentrated on the modality of subsidence and its clinical impact. We performed a retrospective analysis of ACDF patients from 2004 to 2010. Numeric analog scale (NAS) score pre-op and post-op, Oswestry Disability Index (ODI) on x-rays, endplate (EP) and cage dimensions, implant position, lordotic/kyphotic subsidence patterns (>5°), and cervical alignment were recorded...

Aims: Transposition of the great arteries (TGA) is generally repaired using the arterial switch operation (ASO) involving coronary transfer. The objective of this prospective study was to determine whether specific coronary Doppler patterns intra-operatively predicted adverse early myocardial events. Methods and results: Patients < 3 months old with TGA undergoing the ASO were eligible. All patients (when feasible) underwent an intra-operative transoesophageal echo (TEE) plus an epicardial echo and had pre-op, early post-op, pre-discharge and follow-up functional echocardiograms...

Shoulder apprehension is more complex than a pure mechanical problem of the shoulder, creating a scar at the brain level that prevents the performance of specific movements. Surgery corrects for shoulder instability at the physical level, but a re-dislocation within the first year is rather common. Predicting which patient will be likely to have re-dislocation is therefore crucial. We hypothesized that the assessment of neural activity at baseline and follow-up is the key factor to predict the post-operatory outcome...

PURPOSE: Needle electromyography provides essential information about the functional aspects of the muscle. But little attention has been given in the literature to needle electromyography examinations in carpal tunnel syndrome. We examined the relationship between preoperative needle electromyography findings and functional recovery of the abductor pollicis brevis (APB) muscle in severe carpal tunnel syndrome patients. METHODS: The subjects of this study were 49 patients, 58 hands, who fit the following 5 criteria: (1) idiopathic carpal tunnel syndrome; (2) pre-op MMT grade of the APB muscle was M0 or M1; (3) APB-CMAP (compound muscle action potential) was not evoked in a median nerve conduction study; (4) needle electromyography of the APB muscle had been done; (5) underwent carpal tunnel release only...

The literature on adrenal gland tumour in HIV-infected patients is scarce. We report a 46-year-old Malay man with HIV and Hepatitis C infection presenting with a large nonfunctioning adrenal tumour. Computed tomography showed a large right adrenal tumour with heterogeneous enhancement and central necrosis. A high index of suspicion of a malignant tumour or pheochromocytoma led us to surgical removal of the adrenal gland. In this case report, we highlight important features to look for during pre-op evaluation of a large adrenal mass...

Trigonocephaly in patients with metopic synostosis is corrected by fronto-orbital remodelling (FOR). The aim of this study was to quantitatively assess aesthetic outcomes of FOR by capturing 3D forehead scans of metopic patients pre- and post-operatively and comparing them with controls. Ten single-suture metopic patients undergoing FOR and 15 age-matched non-craniosynostotic controls were recruited at Great Ormond Street Hospital for Children (UK). Scans were acquired with a three-dimensional (3D) handheld camera and post-processed combining 3D imaging software...

HYPOTHESIS: Cochlear duct length (CDL) can be automatically measured for custom selection of cochlear implant (CI) electrode arrays. BACKGROUND: CI electrode array selection can be influenced by measuring the CDL, which is estimated based on the length of the line that connects the round window and the lateral wall of the cochlea when passing through the modiolus. CDL measurement remains time consuming and inter-observer variability has not been studied. METHODS: We evaluate an automatic approach to directly measure the two-turn (2T) CDL using existing algorithms for localizing cochlear anatomy in computed tomography (CT)...

Management of bilateral Wilms' tumor is particularly challenging, considering the chances of recurrence and long-term renal function for affected patients. Aggressive surgical resection to prevent recurrence must be balanced with the desire to preserve renal function. We evaluated our experience in the management of bilateral Wilms' tumor stressing the challenges encountered in decision making and the role of nephron sparing surgery. We had four children presenting with bilateral Wilms' tumor. All of them were appropriately staged and given standard chemotherapy as per NWTS-5 guidelines...
