Supracoronary ascending aortic replacement in patients with acute aortic dissection type A: What happens to the aortic root in the long run?

2013

ObjectiveOur objective was to determine long-term outcome predictors for patients with acute aortic dissection type A (AADA) and aortic root involvement.MethodsFrom 2001 through 2009, 119 of 152 patients operated on for AADA at a tertiary medical center underwent supracoronary ascending aortic replacement (52 women; mean age, 61 ± 15 years). Those with at least 1-year follow-up (n = 97) were retrospectively assessed for preoperative aortic root disease. Follow-up data were assessed for evidence of new-onset aortic root disease by computed tomography and echocardiography, and for reoperation for aortic root disease.ResultsMedian follow-up was 33.8 months (range, 0-112 months). Twenty-six (27…

The Use of Computer Navigation in Total Hip Arthroplasty Is Associated with a Reduced Rate of Revision for Dislocation

2021

BACKGROUND: The use of computer navigation has been shown to produce more accurate cup positioning when compared with non-navigated total hip arthroplasty (THA), but so far there is only limited evidence to show its effect on clinical outcomes. The present study analyzed data from the Australian Orthopaedic Association National Joint Replacement Registry to assess the impact of computer navigation on the rates of all-cause revision and revision for dislocation following THA. METHODS: Data for all non-navigated and navigated primary THAs performed for osteoarthritis in Australia from January 1, 2009, to December 31, 2019, were examined to assess the rate of revision. We analyzed the effects …

XEN-augmented Baerveldt Implantation for Refractory Childhood Glaucoma: A Retrospective Case Series

2019

Background Tube implants can lead to long-term decompensation of the cornea after decades, in particular in complicated childhood glaucoma, because of a variety of causes including contact between the tube tip and the corneal endothelium. The augmentation of a XEN implant with a Baerveldt (250) tube implant, introduced 2016 by Mermoud et al for refractory glaucoma in adult patients, may reduce this risk in children. In our retrospective study, we report on the XEN-augmented Baerveldt (250) tube implant in children. Patients and methods Ten consecutive patients with refractory childhood glaucoma who underwent XEN-augmented Baerveldt implantation by a single surgeon (F.G.) between January 201…

Contemporary results with the biosynthetic glutaraldehyde denatured ovine collagen graft (Omniflow II) in femoropopliteal position

2020

Abstract Objective The objective of this study was to analyze the outcome of a contemporary series of femoropopliteal bypass operations with the glutaraldehyde denatured polyester mesh-reinforced ovine collagen prosthesis (OCP; Omniflow II [LeMaitre Vascular, Inc, Burlington, Mass]). The experience of two tertiary centers regarding long-term graft function, secondary reinterventions, and biodegeneration of the OCP prosthesis is presented. Methods Between January 2006 and January 2014, a series of 205 consecutive operations with the OCP in the femoropopliteal position (54 above knee and 151 below knee) were performed in 194 patients in 202 limbs for disabling claudication (72), chronic criti…

Ultrasound-Guided Periprosthetic Biopsy in Failed Total Hip Arthroplasty: A Novel Approach to Test Infection in Patients With Dry Joints

2021

Background: To diagnose periprosthetic joint infection (PJI) preoperatively, ultrasound-guided joint aspiration (US-JA) may not be performed when effusion is minimal or absent. We aimed to report and investigate the diagnostic performance of ultrasound-guided periprosthetic biopsy (US-PB) of synovial tissue to obtain joint samples in patients without fluid around the implants. Methods: One-hundred nine patients (55 men; mean age: 68 ± 13 years) with failed total hip arthroplasty (THA) who underwent revision surgery performed preoperative US-JA or US-PB to rule out PJI. Results: Sixty-nine of 109 patients had joint effusion and underwent US-JA, while the remaining 40 with dry joint re…

Use and durability of femoral vein for autologous reconstruction with infection of the aortoiliofemoral axis.

2014

Objective To analyze early and late mortality, venous morbidity, reinfection, and freedom from reintervention after using the femoral vein (FV) for vascular reconstruction with infection of the aortoiliofemoral axis. Methods By reviewing our database, 86 patients could be identified with implantation of FV grafts in infected fields between November 1995 and July 2012. The patient records were retrospectively analyzed and follow-up information obtained from patients or their general physician. Seventy-one patients presented with prosthetic graft infection and 15 with an infected aneurysm. For data analysis, patients were divided into an aortoiliac (n = 67) and a femoral group (n = 19). Study…

Endovascular Aneurysm Sealing (EVAS) and Chimney EVAS in the Treatment of Failed Endovascular Aneurysm Repairs

2016

Purpose: To assess the technical success and clinical outcome of reinterventions using the Nellix Endovascular Aneurysm Sealing (EVAS) System to treat complications after endovascular aneurysm repair (EVAR). Methods: Fifteen consecutive patients (mean age 79 years; 14 men) with prior EVAR were treated with EVAS between March 2014 and December 2015 at 2 institutions. The failed prior EVARs included 13 bifurcated endografts, 1 bifurcated graft plus fenestrated cuff, and 1 tube endograft. Endoleaks were the predominant indications: type Ia in 10 and type III in 5 (3 type IIIa and 2 type IIIb). All patients presented with progressive aortic aneurysms (median 7.85-cm diameter; range 6.5–11). Ei…

Transgraft sac Embolization Combined with Graft Reinforcement for Refractory Mixed-Type Endoleak.

2018

International audience; An 80-year-old female underwent EVAR 4 years ago. She presented type II endoleak with sac expansion from 68 to 80 mm during 3-year follow-up after EVAR. Although she underwent translumbar percutaneous sac embolization, the AAA sac continued to enlarge, suggesting mixed-type endoleak including type I, II, and III. Transgraft direct sac angiography revealed endoleak cavity without demonstrable feeding vessel. Transgraft sac embolization using n-butyl cyanoacrylate and graft reinforcement was performed concurrently, without complications. The graft reinforcement consisted of graft extension for eliminating occult type I endoleak, and relining for eliminating occult type…

Infrapopliteal Composite Bypass with Autologous Vein and Second Generation Glutaraldehyde Stabilized Human Umbilical Vein (HUV) for Critical Lower Li…

2007

Objective. To audit a single center consecutive series of infrapopliteal composite bypasses with second generation glutaraldehyde stabilized human umbilical vein. Design. Retrospective study. Patients. From January 1996 to July 2006 89 femoro-distal bypasses were constructed in 85 patients with HUV and residual vein segments as composite grafts in the absence of sufficient length of autologous vein. Methods. All patients with infrainguinal bypass operations were registered prospectively. Bypasses to infrapopliteal arteries performed with HUV-composite grafts were reviewed for graft patency, limb salvage, patient survival and possible biodegeneration of the HUV. Results. Early graft thrombos…
