The Role of Third Ventriculostomy in the Management of Obstructive Hydrocephalus
2003
Objective: Endoscopic third ventriculostomy (ETV) is an effective treatment for occlusive hydrocephalus caused by an obstruction of the CSF flow in the aqueduct or the posterior fossa. We evaluated the factors age, pathology and surgical technique on the results of the ETV. Methods: Between November 1992 and October 2000 171 ETV have been performed in 159 patients. The follow-up was evaluated in 150 patients. The age ranged from 10 days to 77 years (mean age 35 years). The hydrocephalus was caused by benign aqueductal stenosis in 77 patients, space-occupying lesions in 59, by intraventricular hemorrhages in 11, and by other causes in 3 patients. The trajectory was planned in 31 patients by …
Long-term clinical outcomes after percutaneous coronary intervention versus coronary artery bypass grafting for acute coronary syndrome from the DELT…
2016
AIMS Our aim was to compare, in a large unprotected left main coronary artery (ULMCA) all-comer registry, the long-term clinical outcome after percutaneous coronary intervention (PCI) with first-generation drug-eluting stents (DES) versus coronary artery bypass grafting (CABG) in patients with acute coronary syndrome (ACS). METHODS AND RESULTS Of a total of 2,775 patients enrolled in the Drug Eluting Stents for Left Main Coronary Artery Disease (DELTA) multicentre registry, 379 (13.7%) patients with ACS treated with PCI (n=272) or CABG (n=107) were analysed. Baseline demographics were considerably different in the two groups before propensity matching. No significant differences emerged for…
CONVERSION FROM COLONIC OR ILEAL CONDUIT TO CONTINENT CUTANEOUS URINARY DIVERSION
2004
ABSTRACT Purpose: After ileal or colonic conduit diversion some patients, particularly adolescents, desire conversion to a continent diversion to improve quality of life. We report our long-term results on conversion from conduit diversion to continent cutaneous diversion. Materials and Methods: Between 1986 and 2001, 39 patients (mean age 24 years, range 6 to 49) underwent conversion from a colonic (21) or ileal conduit (18) to an ileocecal pouch (Mainz pouch I) with a mean followup of 102 months (range 18 to 192). Conversion was performed after a mean of 11 years (range 1 to 36) of conduit urinary diversion by incorporating the preexisting colonic/ ileal conduit and the ileocecal pouch. R…
Cardiac disease in patients with mucopolysaccharidosis: presentation, diagnosis and management
2011
The mucopolysaccharidoses (MPSs) are inherited lysosomal storage disorders caused by the absence of functional enzymes that contribute to the degradation of glycosaminoglycans (GAGs). The progressive systemic deposition of GAGs results in multi-organ system dysfunction that varies with the particular GAG deposited and the specific enzyme mutation(s) present. Cardiac involvement has been reported in all MPS syndromes and is a common and early feature, particularly for those with MPS I, II, and VI. Cardiac valve thickening, dysfunction (more severe for left-sided than for right-sided valves), and hypertrophy are commonly present; conduction abnormalities, coronary artery and other vascular in…
The preoperative assessment of stroke risk in lesions involving the internal carotid artery.
1995
Patients with vascular or tumourous lesions involving the internal carotid artery are at risk of damage or occlusion of this vessel during surgical or endovascular procedures. To assess the stroke risk transcranial Doppler aided carotid compression tests were performed in 82 patients. Based on changes of blood flow velocity (BFV), pulsatility index, systolic/diastolic ratio and length of transient hyperaemic response three groups could be differentiated. Patients in group A (31%) showed only a slight reaction of BFV and were at minimal risk in case of carotid occlusion. Patients in group B (52%) underwent a distinct decrease of Doppler readings with partial improvement and were considered t…
Refinements in buccal mucosal graft urethroplasty for hypospadias repair
1998
We evaluated our experience with buccal mucosa in urethral reconstruction for complex hypospadias repair in a total of 62 children operated on at our institution since 1990 at a mean follow-up of 23 months. After the graft had been taken from the lower lip, with possible extension to the inner cheek, complete thinning of the graft was performed. The graft was then sutured in an onlay fashion to the urethral plate, and suprapubic urinary diversion was carried out for 3 weeks. The overall complication rate in this rather complex series of patients, including 26 "hypospadias cripples," was 13%; the complications involved 4 fistulas, 3 cases of graft necrosis, and only 1 meatal stenosis during …
Long-term followup of the intussuscepted ileal nipple and the in situ, submucosally embedded appendix as continence mechanisms of continent urinary d…
2006
We analyzed stoma related complications and continence rates in patients who underwent continent urinary diversion with the cutaneous ileocecal pouch (Mainz pouch I). We compared the intussuscepted ileal nipple and in situ, submucosally embedded appendix as continence mechanisms.A total of 401 patients were included in a retrospective followup study. Continence mechanisms were the intussuscepted ileal nipple in 205 patients and the in situ, submucosally embedded appendix in 196.A total of 144 patients (36%) required intervention for a stomal complication. Of patients who received an intussuscepted ileal nipple 34 (17%) had stomal stenosis at a mean time to first stenosis of 43.8 months, 41 …
Fragment reconstruction of coronary arteries using transesophageal echocardiography for coronary diagnostics
2008
Aims Ultrasound differs procedurally from the established methods for non-invasive coronary visualization and is therefore an interesting alternative for non-invasive diagnostics. In this study, fragment reconstruction of coronary arteries by transesophageal echocardiography (FRC-TEE) was investigated for the first time in a patient population being evaluated for coronary angiography. Methods and results Ultrasonic and angiographic findings were compared visually and using quantitative measurements in 50 patients. One hundred and seventy-one vessels were examined by FRC-TEE. The total lengths visualized were 9.6+ 1.7 cm for the right coronary artery, 7.0+ 1.1 cm for left circumflex, 3.9+ 1.…
Advancement flap in the management of chronic anal fissure: A prospective study
2012
Lateral internal sphincterotomy is the surgical treatment of choice of chronic anal fissure after failure of conservative measures. Several randomized trials identified an overall risk of incontinence of 10 % mostly for flatus. Fissurectomy is the most commonly used procedure to preserve the integrity of the anal sphincters. However, a possible complication is keyhole defect that may lead to faecal soiling. In this study, chronic anal fissure (CAF) was treated by fissurectomy and anal advancement flap to preserve the anatomo-functional integrity of sphincters and to reduce healing time and the risk of anal stenosis. In patients with hypertonia, surgical treatment was combined with chemical …
Accuracy of magnetic resonance enterography in the preoperative assessment of patients with Crohn's disease of the small bowel
2016
Aim to assess the accuracy of magnetic resonance-enterography in predicting the extension, location and characteristics of the small bowel segments affected by Crohn's disease. Method This is a prospective study including a consecutive series of 38 patients with small bowel Crohn's disease who underwent surgery at a specialized colorectal unit of a tertiary hospital. Preoperative magnetic resonance enterography was performed in all patients, following a homogeneous protocol, within the three months prior to surgery. A thorough exploration of the small bowel was performed during the surgical procedure, using calibration spheres, according to the discretion of the surgeon. The accuracy of mag…
