Tailored approaches for transcatheter closure of postsurgical pseudoaneurysms from the ascending aorta and brachiocephalic artery.

ABSTRACT: Ascending aortic pseudoaneurysms following open-heart surgery are treated by redo surgery or endovascular therapy when surgical risks are high. Extreme variations in their morphology, proximity to coronary and arch branches and vascular access may vary the timing, strategy, device choice, and technique in each patient. Three patients with varying etiology, presentations, and morphology of the pseudoaneurysms underwent successful endovascular exclusion by individually tailored strategies. The approach includes optimal treatment of the underlying infections before the endovascular intervention despite the emergency to treat the condition; choosing appropriate device depending on the proximity to aortic branches, choosing appropriate access depending on the angulation of the entry of pseudoaneurysm to the aortic lumen, and use of adequate imaging for achieving procedural success. <Learning objective: A tailored approach for transcatheter closure of postsurgical ascending aortic pseudoaneurysms should include: 1 Optimal infection control before the intervention. 2 Choosing nitinol occluders in high-flow aneurysms; vascular plugs and coils for residual leaks; and embolic protection for high clot burden. 3 Choice of femoral, brachial, or transapical access is decided based on angulation of the aneurysm with ascending aorta. 4 Meticulous planning of the interventions based on advanced three-dimensional imaging.>.

Transcatheter closure of postsurgical aortic pseudoaneurysms guided by three-dimensional image reconstruction: a single-centre experience.

Project description:BackgroundPostsurgical thoracic aortic pseudoaneurysms (PTAPs) are a potentially lethal complication after cardiac or aortic surgery. Surgical management can pose a challenge with high in-hospital mortality rates. Transcatheter closure is a less-invasive alternative treatment option for selected patients, although current experience is limited.AimsWe aimed to evaluate procedural and imaging outcomes of our first 11 cases of transcatheter PTAP closure with the use of closure devices.MethodsPatients with a high operative risk who underwent transcatheter PTAP closure at our centre from 2019 to 2021 were retrospectively included. Suitability was evaluated on preprocedural computed tomography (CT) scans and three-dimensional (3D) reconstructions. All procedures were performed in the catheterisation laboratory. Intraprocedural aortography and postprocedural CT scans with 3D reconstructions were used to evaluate PTAP occlusion.ResultsEleven consecutive patients with a high operative risk and a history of cardiac/aortic surgery who underwent transcatheter PTAP closure were included. PTAPs were predominantly located at the proximal or distal anastomosis of a supracoronary ascending aortic vascular graft or Bentall prosthesis (82%). Implanted closure devices included Amplatzer Valvular Plug III (82%), Amplatzer septal occluder (9%) and Occlutech atrial septal defect occluder (9%). No periprocedural complications occurred. After device deployment, residual flow was absent on aortography in 64% and minimal residual flow was present in 36% of patients. Subtotal or total occlusion of the PTAP on follow-up CT ranged between 45% and 73%.ConclusionsAlthough subtotal or total occlusion of the PTAP was found at follow-up in only 45-73% of cases, transcatheter PTAP closure guided by preprocedural 3D reconstructions can offer a valuable minimally invasive primary treatment option for patients who otherwise would face a high-risk reoperation.

Minimally invasive closure of a progressive pseudoaneurysm of the ascending aorta: A case report.

Project description:Ascending aortic pseudoaneurysm (AAP) is rare but may cause life-threatening complications. Although the placement of a stent graft and the use of occluder devices and vascular plugs to exclude pseudoaneurysm are adopted for some patients, the management of progressive pseudoaneurysms that may rupture at any time remains a challenge that needs to be addressed. In this study, we present the case of a patient with an AAP that was caused by aortic and mitral valve replacement for the giant left ventricle. Aortic pseudoaneurysm was suspected on the basis of a spherical cystic echo (70 × 80 mm) of the ascending aorta; this pseudoaneurysm was detected by an ultrasonic cardiogram, and the diagnosis was confirmed by an aortic computed tomography angiography (CTA) examination. To prevent the unexpected rupture of a progressive pseudoaneurysm, our patient was treated with a 28- mm ASD occluder without any procedural complications. Our patient has a good prognosis, which will inspire clinicians to choose minimally invasive procedures when dealing with such high-risk cases in emergency situations.

Femoral artery anatomy-tailored approach in transcatheter aortic valve implantation.

Project description:The best techniques for reduction of femoral access site complications after transcatheter aortic valve implantation (TAVI) remain the object of research.We report on a single center's experience with TAVI performed via the femoral access site.Between September 2010 and September 2015, 152 consecutive patients underwent TAVI in our department. Of them, 101 patients with CoreValve implantation from the femoral access site were included in the analysis. The femoral artery anatomy-tailored approach was introduced in 2013 in order to reduce the rate of access-site complications. Patients were assigned to percutaneous puncture or surgical cut-down depending on the femoral artery anatomy assessed in computed tomography. The study patients were divided into two subgroups: group A - patients treated before January 2013, before introduction of the tailored approach program (n = 34); and group B - patients treated between January 2013 and April 2015 (n = 67).The access site complication rate significantly decreased from 35.3% in group A (n = 12) to 7.5% in group B (n = 5) (p = 0.0012). Both minor and major access site complications were more frequent in group A (p = 0.04 and 0.016, respectively). In-hospital mortality was 8.8% (n = 3) in group A and 1.5% (n = 1) in group B (p = 0.1).The femoral artery anatomy-tailored approach significantly reduces the incidence of access site complications in TAVI patients.

Inferior epigastric artery pseudoaneurysms.

Project description:Inferior epigastric artery (IEA) pseudoaneurysms are recognised complications of abdominal wall procedures, and a variety of approaches including surgical excision and ligation, percutaneous procedures and conservative management have been employed in treating this rare complication.We describe a case of an IEA pseudoaneurysm diagnosed on computed tomography (CT) angiography, 14 days following a laparoscopic assisted low anterior resection, which was managed successfully with surgical excision and ligation. A review of the literature identified 32 reports of this complication since 1973 with 69% of cases occurring since 2000.The main aetiology of IEA pseudoaneurysm was abdominal surgery (n=20); 65% of cases were attributable to abdominal wound closure or laparoscopic surgery. Two-thirds (66%) of patients presented between 11 and 63 days, and all except 1 case presented with discomfort, abdominal mass or haemodynamic instability. Colour Doppler ultrasonography was the imaging modality of choice (n=18), either alone or in combination with computed tomography and/or angiography. Surgical ligation and excision and percutaneous coil embolisation formed the mainstay of attempted treatments (69%), particularly following treatment failure using an alternative technique.The incidence of iatrogenic IEA pseudoaneurysms appears to be increasing. Awareness of this rare complication is of clinical importance to avoid excessive morbidity for affected individuals.

Effect of Concomitant Coronary Artery Bypass Grafting on Outcomes of Ascending Aorta Replacement.

Project description:BackgroundAscending aorta replacement can be performed safely in high-volume centers. What remains unknown is whether concomitant coronary revascularization with bypass grafting affects postoperative outcomes.MethodsThis study retrospectively reviewed a prospectively maintained institutional database for patients who underwent ascending aorta replacement (AAR) during the period from 1997 to 2018. Patients were stratified into AAR alone (AAR) vs AAR and coronary artery bypass graft (AAR with CABG), further categorized as 1 or more than 1 CABG. Aortic dissection and root replacement cases were excluded. The primary end point consisted of major adverse events (MAE), including operative mortality, perioperative myocardial infarction, stroke, need for tracheostomy, and need for dialysis. Secondary end points were operative mortality, each MAE component, and late survival.ResultsA total of 951 patients were included in the analysis; 725 (76.2%) underwent isolated AAR, and 226 (23.8%) underwent AAR with CABG. Operative mortality was similar across the 2 groups (1.8% for AAR with CABG and 0.8% for AAR; P = .40). The unadjusted incidence of MAE was higher in the AAR with CABG group (5.8% vs 1.9%; P = .005).). On multivariable analysis, the performance of 1 CABG (odds ratio [OR], 1.90; 95% confidence interval [CI], 0.67 to 5.33; P = .23) and more than 1 CABG (OR, 2.65; 95% CI, 0.93 to 7.53; P = .07) was not associated with higher rates of MAE. Preoperative pulmonary dysfunction (OR, 2.51; 95% CI, 1.07 to 5.85; P = .03) was the only independent predictor of MAE.ConclusionsIn patients undergoing concomitant CABG with AAR, the performance of concomitant CABG is not associated with an increased risk of MAE.

Dissection of Ascending Aorta: A Complication of Transradial Artery Access of Coronary Procedure.

Project description:Iatrogenic acute dissection of ascending aorta following coronary angiography and percutaneous intervention is a rare complication. Most reports involve localized aortic dissections as a complication of cannulation of a coronary artery with propagation into the ascending aorta. It is usually treated by sealing the intima with a stent in the ostium of the coronary artery or conservative management, while extensive dissections may require a surgical intervention. We describe a case of the subclavian dissection extending into the ascending aorta that occurred during diagnostic catheterization using the radial approach. The patient was successfully treated utilizing conservative management.

Management of ascending aorta perforation during transseptal puncture for left atrial appendage closure: a case report.

Project description:BackgroundAn 82-year-old female with a history of atrial fibrillation and repeated episodes of major bleeding on direct oral anticoagulant therapy, with a high risk for thromboembolism and was referred for left atrial appendage closure.Case summaryDuring the procedure, an unrecognized puncture of the aorta by the transseptal puncture (TSP) needle and inadvertent advancement of the sheath resulted in ascending aorta perforation. This perforation was closed percutaneously using an Amplatzer™ Duct Occluder (ADO). Reversal of heparinization with protamine sulphate was given to avoid intractable bleeding. However, this resulted in thrombus formation and subsequent embolization causing an ST-elevation myocardial infarction. This was treated with balloon dilatation and thrombus aspiration with subsequent Thrombolysis in Myocardial Infarction 3 flow.DiscussionInadvertent ascending aorta perforation is a rare yet serious complication that can occur during TSP. Percutaneous closure using an ADO is a viable management option. The reversal of heparin carries a risk of thrombus formation and should be avoided in cases where there is no evidence of overt bleeding.
