LATE-ONSET OCULAR HYPERTENSION AFTER VITRECTOMY: A Multicenter Study of 6,048 Eyes
2018
Purpose: To determine the incidence and risk factors for late-onset ocular hypertension (LOH) after vitrectomy. Methods: From the electronic medical records of consecutive patients who underwent primary vitrectomy, from January 2010 to December 2015, at 5 tertiary vitreoretinal centers in Italy, patient demographics, systemic, ophthalmic, operative, and postoperative data were drawn. Main outcome measure was the presence of LOH, defined as intraocular pressure >21 mmHg detected more than 2 months after vitrectomy on at least 2 consecutive visits. Results: Among 6,048 patients, LOH was found in 294 (4.9%) vitrectomized eyes and in 87 (1.4%) fellow eyes, (chi square; P < 0.001). Multiva…
Pre and postoperative evaluation of transcranial Doppler pulsatility index of the middle cerebral artery in patients with severe carotid artery steno…
2016
In the management of severe carotid artery stenosis particular importance must be given to the evaluation of the risk of perioperative cerebral ischemic events. Our study analysed the possible relationship between the pre-operative middle cerebral artery Gosling Index, calculated after transcranial Doppler (TCD), and intra-operative stump pressure (SP), in order to identify patients with higher risk of ischemic accidents. Moreover, we studied pre- and post- operative Gosling Index values in association with possible events during follow-up. In a one-year time lapse 47 patients underwent either carotid endoarterectomy (CEA) or carotid artery stenting (CAS) with proximal embolic protection sy…
TREATMENT OF PERSISTENTLY OPEN MACULAR HOLES WITH HEAVY SILICONE OIL (DENSIRON 68) VERSUS C2F6. A PROSPECTIVE RANDOMIZED STUDY
2016
Abstract PURPOSE: To compare the efficacy of a mixture of silicone oil and perfluorohexyloctane (Densiron 68) with C2F6 gas endotamponade in the retreatment of persistently open full-thickness macular holes. METHODS: In this prospective randomized study, 21 consecutive patients who were unsuccessfully operated on for large idiopathic full-thickness macular hole were randomly assigned to undergo a second vitrectomy with 20% perfluoroethane gas (C2F6, Group A) or with Densiron 68 tamponade (Group B). PRIMARY OUTCOMES: Endpoint (12 months) full-thickness macular hole closure rate by spectral domain optical coherence tomography and logMAR corrected distance visual acuity. SECONDARY OUTCOMES: po…
Optical coherence tomography angiography evaluation of peripapillary microvascular changes after rhegmatogenous retinal detachment repair
2021
PURPOSE To evaluate the radial peripapillary capillary plexus (RPCP) vessel density (VD) and the retinal nerve fiber layer (RNFL) thickness in eyes successfully treated with pars plana vitrectomy for primary rhegmatogenous retinal detachment. METHODS In this cross-sectional multicenter clinical study, eyes with a minimum 12-month follow-up were reexamined. The RPCP VD and RNFL thickness in the rhegmatogenous retinal detachment subfields of the affected eye (study group) were compared with the corresponding areas of the healthy fellow eyes (control group). RESULTS Fifty-three eyes were included in the study. A significantly lower RPCP VD and RNFL thickness were observed in those subfields af…
Long-term follow-up study of endarterectomy versus angioplasty in patients with symptomatic severe carotid stenosis trial
2014
Background and Purpose— We aimed at comparing the long-term benefit–risk balance of carotid stenting versus endarterectomy for symptomatic carotid stenosis. Methods— Long-term follow-up study of patients included in Endarterectomy Versus Angioplasty in Patients With Symptomatic Severe Carotid Stenosis (EVA-3S), a randomized, controlled trial of carotid stenting versus endarterectomy in 527 patients with recently symptomatic severe carotid stenosis, conducted in 30 centers in France. The main end point was a composite of any ipsilateral stroke after randomization or any procedural stroke or death. Results— During a median follow-up of 7.1 years (interquartile range, 5.1–8.8 years; maximum 1…
Treatment of stages IIIIV of the Dupuytrens Disease using a personal approach: percutaneous needle fasciotomy (PNF) and minimal invasive selective ap…
2013
Abstract The authors present their experience in treating 23 fingers on 20 patients affected by Dupuytrens Disease in stages III and IV of the Tubiana classification with their personal technique that involves the percutaneous needle fasciotomy followed 40 days after by a selective open aponeurectomy on the previously treated cord, by making a small cutaneous incision. The treatment requires careful selection of the patients. In fact, patients suffering from the disease for more than 5 years and all the cases with a suspicion of joint rigidity are excluded from the study. The average follow up period was approximately 48 months. 18 out of the 20 patients had excellent functional recovery. S…
Features Associated with Recurrence Beyond 5 Years After Nephrectomy and Nephron-Sparing Surgery for Renal Cell Carcinoma: Development and Internal V…
2014
Background: Approximately 10-20% of recurrences in patients treated with nephrectomy for renal cell carcinoma (RCC) develop beyond 5 yr after surgery (late recurrence). Objective: To determine features associated with late recurrence. Design, setting, and participants: A total of 5009 patients from a multicenter database comprising 13 107 RCC patients treated surgically had a minimum recurrence-free survival of 60 mo (median follow-up [FU]: 105 mo [range: 78-135]); at last FU, 4699 were disease free (median FU: 103 mo [range: 78-134]), and 310 patients (6.2%) experienced disease recurrence (median FU: 120 mo [range: 93-149]). Interventions: Patients underwent radical nephrectomy or nephron-…
Anastomotic Pseudoaneurysm Complicating Renal Transplantation: Treatment Options
2010
Introduction: Anastomotic pseudoaneurysm following renal transplantation is uncommon. Indications for repair, treatment options and outcomes remain controversial. Report: We present 6 renal transplant recipients with large anastomotic pseudoaneurysms. Five of the patients underwent open repair while one had a stent-grafting and delayed transplant nephrectomy for a ruptured pseudoaneurysm. A transplant nephrectomy was needed in all cases but one. Arterial reconstruction enabled limb salvage in all cases. One patient died of sepsis postoperatively. No patient presented late infection, failure of vascular reconstruction, nor pseudoaneurysm recurrence. Conclusions: Surgical excision of anastomo…
Elective segmental ureterectomy for transitional cell carcinoma of the ureter: Long-term follow-up in a series of 73 patients
2012
What's known on the subject? and What does the study add? Upper Urinary Tract (UUT) Transitional Cell Carcinoma (TCC) is an uncommon disease and represents approximately 5% of all urothelial carcinomas. We report our series on 73 patients treated with Kidney Sparing Surgery for UUT TCC. Good results have been achieved in terms of oncological outcome comparing this conservative approach to the radical nephrourectomy. OBJECTIVES: • To report the long-term oncological outcome in patients with transitional cell carcinoma of the ureter electively treated with kidney-sparing surgery. • To compare our data with the few series reported in the literature. PATIENTS AND METHODS: • We considered 73 pat…
Heavy versus standard silicone oil in the management of retinal detachment with macular hole in myopic eyes
2011
PURPOSE: The purpose of this study was to compare pars plana vitrectomy (PPV) with 1000 cSt silicone oil endotamponade and PPV with densiron endotamponade for retinal detachment with macular hole and posterior staphyloma in highly myopic eyes. PATIENTS AND METHODS: In a prospective study, 30 eyes of 30 patients were randomly assigned to PPV and densiron (n = 15) or PPV with silicone oil (n = 15). All eyes had laser photocoagulation of the macular hole rim after PPV. Silicone oil or densiron was removed 12 weeks after surgery. Patients were followed-up for 6 months after oil removal. RESULTS: In the densiron group, the retinal reattachment rate was 100% with densiron in situ and 87% after it…
