Long term follow up after percutaneous closure of PFO in 357 patients with paradoxical embolism: Difference in occlusion systems and influence of atr…
2009
Abstract Background Percutaneous transcatheter closure of patent foramen ovale (PFO) in cryptogenic stroke or TIA is an alternative to medical therapy especially in patients with atrial septal aneurysm (ASA). The differences in time to complete occlusion for various closure devices in PFO alone and PFO plus ASA are of natural interest. Methods and results Between January, 1st 1998 and November, 30th 2006 percutaneous PFO closure was performed in 357 patients with a history of ≥1 paradoxical embolism using three different devices: Amplatzer PFO-( n =199), Starflex-( n =48) and Helex Occluder ( n =110). All patients were assigned to a post-interventional protocol with contrast-enhanced transe…
Descriptive and follow-up study of patients treated surgically for abdominal aortic aneurysm at tertiary hospitals in Spain.
2019
BACKGROUND The aim of this study was to assess potential variability in the clinical characteristics and treatment of patients undergoing elective surgery for abdominal aortic aneurysm (AAA) across five hospitals in Spain. METHODS Multicenter, retrospective cohort study of patients diagnosed with AAA and treated with open surgical repair (OSR) or endovascular aneurysm repair (EVAR). We evaluated clinical and demographic variables, including comorbidity (Charlson Comorbidity Index [CCI]); anatomic characteristics; surgical risk (ASA Score); aneurysm characteristics; and in-hospital and overall mortality. All patients were followed for three years. RESULTS A total of 186 patients were include…
Multiple periscope and chimney grafts to treat ruptured thoracoabdominal and pararenal aortic aneurysms
2011
Purpose: To report midterm outcomes after urgent endovascular repair of ruptured pararenal or thoracoabdominal aortic aneurysms using multiple periscope and chimney grafts to preserve renovisceral branch perfusion and facilitate aneurysm exclusion. Methods: Nine consecutive men (mean age 72614 years, range 40–88) presenting with ruptured thoracoabdominal (n56), pararenal (n52), or infrarenal (n51) aortic aneurysm underwent urgent endovascular repair with at least 1 periscope graft delivered via a transfemoral access; chimney grafts were installed from an axillary access. In all, 17 periscope and 7 chimney grafts were used to reperfuse 11 renal and 13 visceral arteries in the 9 patients. The…
Femtosecond laser–assisted intrastromal corneal ring segment implantation for high astigmatism correction after penetrating keratoplasty
2013
PURPOSE: To assess the visual and refractive outcomes of femtosecond laser-assisted implanta- tion of Ferrara-type intrastromal corneal ring segments (ICRS) in post-penetrating keratoplasty (PKP) eyes. SETTING: Instituto OftalmolFernOviedo, Spain. DESIGN: Cohort study. METHODS: Patients with previous PKP had ICRS implantation after femtosecond laser tunnel creation. The uncorrected (UDVA) and corrected (CDVA) distance visual acuities and residual refractive errors were recorded before and 6 months after ICRS implantation. The power vector method was used to analyze refractive errors preoperatively and postoperatively. RESULTS: This study enrolled 32 eyes of 30 patients. The mean UDVA (Snell…
Endovascular treatment as first choice in chronic intestinal ischemia.
2002
The purpose of this study was to define the place of endovascular treatment in chronic intestinal ischemia (CII). We report here a series of 19 consecutive patients treated with percutaneous angioplasty of the intestinal arteries. We excluded patients with acute ischemia, from the study. From January 1, 1989 to December 31, 2001, 19 patients with symptomatic CII were treated by endovascular techniques. This study group included 11 men and 8 women with a mean age of 59 years (range 30 to 90 years). The clinical presentation included postprandial pain in 16 patients, weight loss in 14 patients, with a mean weight loss of 7.4 kg (range 0 to 30 kg); and gastroparesis in 2 patients. Stenoses wer…
The impact of Syme amputation in surgical treatment of patients with diabetic foot syndrome and Charcot-neuro-osteoarthropathy
2002
Charcot-neuro-osteoarthropathy with its severe destruction of bones remains a challenge for physicians and surgeons. The aim of the study was to characterise a patient population treated in a specialised foot care centre who underwent surgical treatment for their diabetic foot syndrome. Special attention was paid to patients who suffered from Charcot-neuro-osteoarthropathy and the impact of Syme amputation if amputation of the foot was inevitable. A total of 121 patients with diabetic foot syndrome and ulcerations underwent an interdisciplinary strategy for diagnostic and therapeutic procedures including MRI and surgical interventions. If peripheral arterial vessel disease was present, reva…
Tension-free hernia repair is associated with an increase in inflammatory response markers against the mesh.
2000
Abstract Background: The purpose of this study was to evaluate the involvement of inflammatory mediators in patients undergoing Lichtenstein tension-free hernioplasty (LH) using polypropylene prosthetic materials or conventional Bassini hernia repair (BH). Methods: Thirty patients male with unilateral inguinal hernia without complications or recurrence were included in this study. Randomly, patients underwent LH or BH. Peripheral venous bloods samples were collected 24 hours prior to surgery and then 6, 24, 48 and 168 hours postoperatively. Results: We present evidences that LH patients showed a higher increased serum level of fibrinogen, C-reactive protein, alpha-1-antitrypsin, and interle…
A European Study of the Performance and Safety of MINIject in Patients With Medically Uncontrolled Open-angle Glaucoma (STAR-II)
2020
Precis In this European study (STAR-II), MINIject, a novel, ab-interno, supraciliary MIGS device, effectively lowered intraocular pressure (IOP) and the need for IOP-lowering medications in patients with primary open-angle glaucoma. Purpose To evaluate the safety and performance of a minimally invasive supraciliary glaucoma drainage device (MINIject DO627, iSTAR Medical SA, Wavre, Belgium) for surgical treatment of primary open angle glaucoma in patients refractory to topical hypotensive medications. Methods In a prospective, interventional, single-arm, multi-center, European study (STAR-II), MINIject was successfully implanted in a standalone procedure in 29 of 31 patients in 8 sites in 3 …
Chimney and periscope grafts to facilitate endovascular treatment of aortic transection in a patient with aberrant right subclavian artery
2014
Purpose: To report the use of parallel grafts to extend the proximal landing zone for stentgraft repair of aortic transection involving an aberrant right subclavian artery (ARSA). Case Report: A 28-year-old patient was referred for treatment of traumatic aortic transection with contained rupture at the level of an ARSA. Immediate thoracic endovascular aortic repair (TEVAR) was planned because of hemodynamic instability. To achieve rapid sealing and maintain perfusion to both subclavian arteries, a chimney stent to the left subclavian artery (LSA) and a periscope stent-graft to the ARSA were deployed successfully. After surgical repair of all fractures, the patient was discharged 1 month aft…
