One-year clinical outcome of biodegradable polymer sirolimus-eluting stent in diabetic patients: Insight from the ULISSE registry (ULtimaster Italian multicenter all comerS Stent rEgistry).

BACKGROUND: The ULISSE registry evaluated the real-world performance of the Ultimaster® biodegradable polymer sirolimus-eluting stent (BP-SES) in a multicenter-independent cohort of patients undergoing percutaneous coronary intervention, including a large proportion of diabetes mellitus (DM) patients. METHODS: In this subgroup analysis, 1,660 consecutive patients, 2,422 lesions, treated with BP-SES enrolled in the ULISSE registry were divided in two groups: DM (485 patients, 728 lesions) and non-DM (1,175 patients, 1,694 lesions). Primary endpoint was target lesion failure (TLF), a composite endpoint of cardiac-death, target-vessel myocardial infarction (TV-MI), and clinically driven target lesion revascularization (TLR) at 1-year. Secondary endpoint was TLR at 1-year. RESULTS: At 1-year follow-up TLF occurred in 5% overall patients and was significantly higher in DM patients (8 vs. 3.7%; p = .001), due to more cardiac deaths (3.4 vs. 1.1%; p = .002). TLR occurred in 3.2% overall patients, and it was not significantly higher in DM compared to non-DM patients (4.4 vs. 2.8%; p = .114). The incidence of stent thrombosis was low and similar between groups (0.4 vs. 0.9%; p = .526). Insulin-treated DM (ITDM) patients showed higher rate of TLF as compared to non-ITDM patients (13 vs. 6.5%; p = .041), but similar rate of TLR (6 vs. 4%; p = .405). After adjustment for relevant comorbidities, DM was not significantly associated with TLF or cardiac death in patients undergoing BP-SES implantation. CONCLUSIONS: This study is the first all-comers evaluation of BP-SES in DM patients. Our findings show that DM patients, mostly those with ITDM, still represent a vulnerable population and experience significantly higher rate of TLF. Overall BP-SES efficacy is considerable, although not statistically significant higher rate of TLR is still present in DM compared to non-DM patients.

One-year clinical outcome of biodegradable polymer sirolimus-eluting stent in patients presenting with acute myocardial infarction: Insight from the ULISSE registry.

BACKGROUND: The ULISSE registry has demonstrated the real-world performance of the Ultimaster biodegradable polymer sirolimus-eluting stent (BP-SES) in a large cohort of patients undergoing percutaneous coronary intervention, including a large proportion of patients presenting with acute myocardial infarction (AMI). METHODS: We performed a subgroup analysis of the ULISSE registry in AMI patients and compared the outcomes of this vulnerable cohort with that of patients presenting without AMI (non-AMI). The primary end point was the incidence of 1-year target lesion failure (TLF), a composite of cardiac death, target vessel myocardial infarction (TV-MI), and clinically indicated target lesion revascularization (TLR). RESULTS: Of 1,660 patients included in the ULISSE registry, 381(23%) presented with AMI, 207(54.3%) non-ST elevation myocardial infarction, and 174(45.7%) ST-elevation myocardial infarction. Compared with non-AMI patients, those with AMI were more frequently female and smokers, with lower left ventricular ejection fraction (LVEF) and chronic kidney disease requiring dialysis. At 1 year, TLF rate was significantly higher in AMI than non-AMI patients (7.9 vs. 4.1%; HR 1.98, CI 95% 1.22-3.23; p = .005) driven by higher rate of cardiac death (4.0 vs. 1.1%; HR 3.59, CI 95% 1.64-7.88; p = .01) and TV-MI (2.8 vs 0.9%; HR 2.99,CI 95% 1.22-7.37; p = .01), without differences in TLR rate (4.3 vs. 2.9%,HR 0.66, CI95% 0.35-1.25; p = .2). At multivariate Cox regression analysis, eGFR <40 mL/min (HR: 2.868) and LVEF <40% (HR: 2.394) were the only independent predictors of TLF. CONCLUSIONS: In AMI patients, Ultimaster BP-SES implantation was associated with higher rate of TLF and definite stent thrombosis compared with non-AMI patients. The high incidence of adverse events was mainly driven by the unfavorable baseline risk profile.

One-year clinical outcome of biodegradable polymer sirolimus-eluting stent in patients needing short dual antiplatelet therapy. Insight from the ULISSE registry (ULtimaster Italian multicenter all comerS Stent rEgistry).

BACKGROUND: This study aimed to evaluate real-world clinical outcome of patients needing short dual antiplatelet therapy (S-DAPT) following PCI with Ultimaster® thin-strut, biodegradable polymer sirolimus-eluting stent (BP-SES), which was supposed to induce faster stent endothelialization and reduce device thrombogenicity. METHODS: In this sub-group analysis of patients enrolled in the ULISSE registry, two groups were identified: 1) patients discharged with S-DAPT (≤3-month) due to high bleeding risk or need for urgent major non-cardiac surgery and 2) patients discharged with recommended DAPT (R-DAPT) duration (≥6-month). The primary ischemic-safety and bleeding-safety endpoints were TLF (composite of cardiac-death, target vessel MI, and clinically driven target lesion revascularization), and BARC major bleedings (≥type-3a) at 1-year follow-up. To account for events occurring before DAPT discontinuation we performed 3-month landmark analysis. RESULTS: 82 patients (5%) were discharged with ≤3-month DAPT (57 ±â€¯27 days), and 1558 patients (94%) were discharged with ≥6-month DAPT (318 ±â€¯75 days). No significant differences between S-DAPT and R-DAPT group were observed in TLF at 1-year (7.9% vs. 4.6%). The rate of BARC major bleeding resulted significantly higher in S-DAPT group (3.9% vs. 0.3%; p = 0.001), with the majority of bleeding events occurring within 3 months. The landmark analysis showed no significant differences in BARC major bleedings between groups (1.4% vs. 0.3%; p = 0.142). CONCLUSIONS: As compared to those treated with R-DAPT (≥6-month), patients needing -S-DAPT (≤3-month) after PCI with Ultimaster® BP-SES had similar rates of 1-year TLF and BARC major bleedings following early DAPT discontinuation.

One-year clinical outcome of biodegradable polymer sirolimus-eluting stent in all-comers population. Insight from the ULISSE registry (ULtimaster Italian multicenter all comerS Stent rEgistry).

BACKGROUND: This study was designed to confirm in a large population of unselected patients the promising results of Ultimaster® biodegradable polymer sirolimus-eluting stent (BP-SES) already shown in previous trial. METHODS: ULISSE is an observational, multicenter, national registry evaluating all patients undergoing PCI with the Ultimaster® BP-SES. Incidence of 1-year TLF (cardiac death or target vessel MI or clinically indicated TLR) was the primary endpoint. Pre-specified subgroup analysis was performed for diabetic patients and for those with lesion longer than 25 mm, bifurcation and CTO lesions. RESULTS: 1660 patients were enrolled in 9 Italian cardiology centers, 82% were males, mean age of 68 ±â€¯10 years, and 29% were diabetics. Overall 2422 lesions were treated, 65% type B2/C lesions, 7% CTOs, 17% bifurcations and 38% long lesions. The incidence of 1-year TLF was 5%, with 3.2% of clinically indicated TLR. TLF occurred in 8% of the patients with diabetes mellitus, and 7% in bifurcation, 6.7% in CTO and 6.2% in long lesions. Definite overall ST was 0.9%, and 1.2% in patients treated for type B2/C lesions. Multivariate logistic regression analysis identified stenting on unprotected LMT (OR = 4.80), stenting on ISR lesion (OR = 3.19) and need for rotational atherectomy (OR = 6.24) as the strongest independent predictors of TLF. CONCLUSIONS: The results of this national all-comers registry show that the Ultimaster® BP-SES real-world performance was comparable with that observed in the clinical trial, with low rate of primary endpoint and TLR. Long term follow-up will be necessary to prove the theoretical advantage of the BP-SES over time.

Aspirin Desensitization in Patients With Coronary Artery Disease: Results of the Multicenter ADAPTED Registry (Aspirin Desensitization in Patients With Coronary Artery Disease).

BACKGROUND: There are limited data on aspirin (ASA) desensitization for patients with coronary artery disease. The aim of the present study was to assess the safety and efficacy of a standard rapid desensitization protocol in patients with ASA sensitivity undergoing coronary angiography. METHODS AND RESULTS: This is a prospective, multicenter, observational study including 7 Italian centers including patients with a history of ASA sensitivity undergoing coronary angiography with intent to undergo percutaneous coronary intervention. A total of 330 patients with history of ASA sensitivity with known/suspected stable coronary artery disease or presenting with an acute coronary syndrome, including ST-segment-elevation myocardial infarction were enrolled. Adverse effects to aspirin included urticaria (n=177, 53.6%), angioedema (n=69, 20.9%), asthma (n=65, 19.7%), and anaphylactic reaction (n=19, 5.8%). Among patients with urticaria/angioedema, 13 patients (3.9%) had a history of idiopathic chronic urticaria. All patients underwent a rapid ASA (5.5 hours) desensitization procedure. The desensitization procedure was performed before cardiac catheterization in all patients, except for those (n=78, 23.6%) presenting with ST-segment-elevation myocardial infarction who underwent the desensitization after primary percutaneous coronary intervention. Percutaneous coronary intervention was performed in 235 patients (71%) of the overall study population. The desensitization procedure was successful in 315 patients (95.4%) and in all patients with a history of anaphylactic reaction. Among the 15 patients (4.6%) who did not successfully respond to the desensitization protocol, adverse reactions were minor and responded to treatment with corticosteroids and antihistamines. Among patients with successful in-hospital ASA desensitization, 253 patients (80.3%) continued ASA for at least 12 months. Discontinuation of ASA in the 62 patients (19.7%) who had responded to the desensitization protocol was because of medical decision and not because of hypersensitivity reactions. CONCLUSIONS: A standard rapid desensitization protocol is safe and effective across a broad spectrum of patients, irrespective of the type of aspirin sensitivity manifestation, with indications to undergo coronary angiography with intent to perform percutaneous coronary intervention.

Radial Versus Femoral Access for Coronary Interventions Across the Entire Spectrum of Patients With Coronary Artery Disease: A Meta-Analysis of Randomized Trials.

OBJECTIVES: The aim of this study was to provide a quantitative appraisal of the effects on clinical outcomes of radial access for coronary interventions in patients with coronary artery disease (CAD). BACKGROUND: Randomized trials investigating radial versus femoral access for percutaneous coronary interventions have provided conflicting evidence. No comprehensive quantitative appraisal of the risks and benefits of each approach is available across the whole spectrum of patients with stable or unstable CAD. METHODS: The PubMed, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases were searched for randomized trials comparing radial versus femoral access for coronary interventions. Data were pooled by meta-analysis using a fixed-effects or a random-effects model, as appropriate. Pre-specified subgroup analyses according to clinical presentation, in terms of stable CAD, non-ST-segment elevation acute coronary syndromes, or ST-segment elevation myocardial infarction were performed. RESULTS: Twenty-four studies enrolling 22,843 participants were included. Compared with femoral access, radial access was associated with a significantly lower risk for all-cause mortality (odds ratio [OR]: 0.71; 95% confidence interval [CI]: 0.59 to 0.87; p = 0.001, number needed to treat to benefit [NNTB] = 160), major adverse cardiovascular events (OR: 0.84; 95% CI: 0.75 to 0.94; p = 0.002; NNTB = 99), major bleeding (OR: 0.53; 95% CI: 0.42 to 0.65; p < 0.001; NNTB = 103), and major vascular complications (OR: 0.23; 95% CI: 0.16 to 0.35; p < 0.001; NNTB = 117). The rates of myocardial infarction or stroke were similar in the 2 groups. Effects of radial access were consistent across the whole spectrum of patients with CAD for all appraised endpoints. CONCLUSIONS: Compared with femoral access, radial access reduces mortality and MACE and improves safety, with reductions in major bleeding and vascular complications across the whole spectrum of patients with CAD.

Hybrid repair of type A acute aortic dissections with the Lupiae technique: ten-year results.

OBJECTIVES: Replacing the ascending aorta and the arch in patients with type A acute aortic dissection achieves good short-term results, but several patients are left with distal intimal tears or a patent false lumen in the descending aorta. In this series, we report the 10-year experience with the Lupiae technique, a hybrid aortic repair technique for patients with type A acute aortic dissection. METHODS: From 2003 to 2013, 89 patients with type A acute aortic dissections underwent replacement of the ascending aorta, the arch, and the rerouting of the neck vessels on the ascending aorta, creating a proximal Dacron landing zone for a completion with thoracic endovascular aortic repair if necessary. RESULTS: In-hospital mortality was 8.9%. In 16 patients, the false lumen healed spontaneously, whereas the remaining 65 patients underwent thoracic endovascular aortic repair. One patient died after thoracic endovascular aortic repair. Eighty patients were followed up. Complete thrombosis of the false lumen was obtained in 93.8% of patients. The median follow-up was 46 ± 35 months. Overall 8-year survival was 93.7% ± 5%, 100% for patients with spontaneously healed residual false lumen after just type A acute aortic dissection repair and 92.3% ± 7.7% for patients who underwent thoracic endovascular aortic repair after type A acute aortic dissection repair. In 10 years, 1 patient underwent a reoperation on the distal aorta (1.25%). CONCLUSIONS: The availability of a Dacron landing zone on the distal ascending aorta after type A acute aortic dissection repair allows the exclusion, with a thoracic endovascular aortic repair, of any residual intimal tear refilling a patent false lumen. This approach seems to be associated with a high probability of false lumen thrombosis and low rates of reoperations on the distal aorta.

Guide-catheter extension system facilitated multiple bioresorbable vascular scaffolds (ABSORB®) delivery in a very long and resistant coronary artery lesion.

We report the case of a 77-year-old male patient who was admitted to our institution for non-ST segment elevation myocardial infarction. Coronary angiography showed a sub-occlusive lesion of the distal left anterior descending artery (LAD) in the context of a diffuse atherosclerotic disease involving a very long segment of the vessel (about 80mm in length by visual estimation). Pre-dilatation was performed in the mid calcified segment of the LAD with a non-compliant balloon inducing vessel dissection. An everolimus-eluting bioresorbable vascular scaffold (EEBVS) was then advanced in the LAD but the first delivery attempt at the distal site failed because of friction between the EEBVS struts and the calcified vessel wall. In order to facilitate EEBVS delivery, a 5Fr catheter system (Heart Rail II, Terumo, Tokyo, Japan) was advanced in the mid LAD within a standard 6Fr guiding catheter facilitating a non-traumatic deep intubation up to the mid LAD. This strategy increased back-up support facilitating the delivery, beyond the site of resistance, of four EEBVS implanted in overlap. This case demonstrated the successful use of a guide catheter extension system to deliver multiple EEBVS in a patient with a long, calcified LAD lesion.

Successful management of a huge thrombus in coronary aneurysmatic dilatation after failed mechanical thrombectomy during acute myocardial infarction.

The benefit of the routine application of aspiration thrombectomy in primary percutaneous coronary intervention (PPCI) is now well established. The optimal management of patients who have 'failed' thrombectomy, characterized by a large residual thrombus burden after repeated mechanical thrombectomy, however, is not known. We report a case of failed aspiration thrombectomy in a 55-year-old man who was admitted to our institution with chest pain non-ST-elevation myocardial infarction due to a huge nonocclusive thrombus in an aneurysmatic segment of the left anterior descending coronary artery. Aspiration thrombectomy did little to reduce thrombus load and so the patient was treated with unfractioned heparin infusion and warfarin. Repeat coronary angiography at 7 days revealed complete thrombus resolution with thrombolysis in myocardial infarction grade 3 anterograde flow.This case demonstrates the potential for appropriate anticoagulation therapy as a treatment option for the management of patients following failed thrombectomy in PPCI.

Directional atherectomy of a heavy calcified axillary artery stenosis inducing critical hand ischemia.

The presence of a severe calcified peripheral artery lesion is responsible for a poor response to balloon dilation, due to significant acute vessel recoil and frequent flow-limiting dissections requiring stent implantation. This possibility could be associated with very high compression and/or fracture rates particularly in cases of lesion located at the mobile joints. In this setting directional atherectomy offers the theoretical advantages of eliminating stretch injury on arterial walls and reducing the restenosis rate by direct plaque excision. In this report, we present a case of critical hand ischemia due to a heavily calcified axillary artery lesion managed by directional atherectomy and balloon angioplasty followed by immediate angiographic success and sustained clinical benefit up to 3 years of follow-up.

Acute Coronary Syndrome in Pre- and Post-partum Women - A Review.

Acute coronary syndrome (ACS) during pregnancy and the post-partum period are weighed by a high mortality rate for the mother and foetus. They should be considered as multifactorial diseases with a special role for sexual hormones. In this setting, ACS is mostly related to an early atherosclerotic disease, even if other conditions are responsible. Indeed, an important part is due to spontaneous coronary artery dissection, more common during delivery and the post-partum period. In the remaining situation, an isolated intracoronary thrombus or a normal angiographic pattern can be found at angiography. Pathophysiology is still uncertain with different hypothetical mechanisms. Prompt diagnosis of ACS and aetiology are essential for an optimal therapeutic strategy. Difficulties in treatment management is a matter for debate, especially in pre-partum women. In the last two decades improvements of diagnostic tools, coronary angiography and subsequent percutaneous treatment have changed the natural history of this rare condition.

Kissing drug-eluting balloons for the treatment of unprotected distal left main bifurcation drug-eluting stent restenosis.

The advent of drug-eluting stents (DES) associated with improvements in interventional techniques, encouraged the use of percutaneous coronary intervention (PCI) for unprotected left main (ULM) stenosis because of the lower need of repeat revascularization compared to the bare-metal stents (BMS). Nevertheless, ULM DES in-stent restenosis (ISR) continues to occur. The choice of treatment strategy (medical treatment, repeated PCI, or coronary artery bypass graft) for ULM DES-ISR depends primarily on several clinical and angiographic factors, making optimal patient selection crucial in the appropriate treatment of ULM-ISR lesions and achievement of favorable long-term outcomes. We describe in this report a successful modern approach to manage a distal ULM DES-ISR following a 2-stent strategy, consisting in the kissing inflation of two DEBs in both branches of the bifurcation.

Hypotension during carotid artery stenting with severe aortic stenosis: the intra-aortic balloon pump option.

This case highlights the importance of intra-aortic balloon pump (IABP) during carotid artery stenting (CAS) in patients with severe aortic stenosis. We report the case of a patient with severe carotid artery disease and aortic stenosis who first underwent CAS using IABP and subsequently underwent aortic valve replacement. We conclude that IABP could be helpful in the staged treatment of patients with concomitant severe carotid artery disease and aortic valve disease.

Usefulness of primary angioplasty in nonagenarians with acute myocardial infarction.

The optimal reperfusion strategy in very elderly patients with ST-segment elevation myocardial infarction is still a subject of debate. The aim of this multicenter study was to determine the medium-term outcomes of nonagenarians after primary percutaneous intervention for ST-segment elevation myocardial infarction. A systematic review of the databases of 7 Italian centers showed that these had performed 5,023 primary angioplasties over the previous 5 years, 100 of which (2%) involved patients > or =90 years old. Thirty-five subjects were in Killip class III or IV at time of presentation, 78 had multivessel coronary artery disease, and mean ejection fraction was 0.40 +/- 0.12%. In-hospital mortality was 19% and was significantly higher in patients with shock (58% vs 10%, p <0.001). Survival rate after 6 months was 68%: 16% in those with Killip class IV at admission and 81% in the remaining patients (p <0.001). Cox regression analysis identified 3 independent predictors of 6-month mortality: cardiogenic shock at presentation (hazard ratio [HR] 10.82, 95% confidence interval [CI] 4.51 to 25.93, p <0.001), Thrombolysis In Myocardial Infarction myocardial flow after percutaneous coronary intervention (HR 0.19, 95% CI 0.07 to 0.50, p = 0.001), and abciximab administration (HR 0.32, 95% CI 0.13 to 0.78, p = 0.01). In conclusion, the results of this multicenter study suggest that selected nonagenarians with acute myocardial infarction benefit from successful primary angioplasty. The treatment does not affect the poor prognosis of patients presenting with cardiogenic shock, but the administration of abciximab seems to have a positive effect on 6-month mortality.

Circulating CD4+CD25hiCD127lo regulatory T-Cell levels do not reflect the extent or severity of carotid and coronary atherosclerosis.

OBJECTIVE: Regulatory T (Treg) cells play a protective role in experimental atherosclerosis. In the present study, we investigated whether the levels of circulating Treg cells relate to the degree of atherosclerosis in carotid and coronary arteries. METHODS AND RESULTS: We studied 2 distinct populations: (1) 113 subjects, selected from a free-living population (carotid study), in which we measured the intima-media thickness of the common carotid artery, as a surrogate marker of initial atherosclerosis; and (2) 75 controls and 125 patients with coronary artery disease (coronary study): 36 with chronic stable angina, 50 with non-ST-elevation acute coronary syndrome, 39 with ST-elevation acute myocardial infarction. Treg-cell levels were evaluated by flow cytometry (Treg cells identified as CD3(+)CD4(+)CD25(high)CD127(low)) and by mRNA expression of forkhead box P3 or of Treg-associated cytokine interleukin 10. In the carotid study, no correlation was observed between Treg-cell levels and intima-media thickness. No differences in Treg-cell levels were observed comparing rapid versus slow intima-media thickness progressors from a subgroup of patients (n=65), in which prospective data on 6-year intima-media thickness progression were available. In the coronary group, Treg-cell levels were not altered in chronic stable angina patients. In contrast, nonunivocal variations were observed in patients suffering an acute coronary syndrome (with a Treg-cell increase in ST-elevation acute myocardial infarction and a Treg-cell decrease in non-ST-elevation acute coronary syndrome patients). CONCLUSIONS: The results suggest that determination of circulating Treg-cell levels based on flow cytometry or mRNA assessment is not a useful indicator of the extent or severity of atherosclerosis.

Distal myocardial protection with intracoronary beta blocker when added to a Gp IIb/IIIa platelet receptor blocker during percutaneous coronary intervention improves clinical outcome.

OBJECTIVE: The present study tested the hypothesis that intracoronary (IC) propranolol improves clinical outcomes with percutaneous coronary intervention (PCI) when used with background Gp IIb/IIIa receptor blockade. BACKGROUND: We have previously shown that administration of a relatively large weight-based IC dose of the beta blocker propranolol before PCI decreases the incidence of post-PCI myocardial infarction (MI) and improves short- and long-term outcome. It has previously been shown that administration of a Gp IIb/IIIa receptor blocker decreases post-PCI MI and improves short- and long-term clinical outcome. METHODS: Patients undergoing PCI (n = 400) were randomized in a prospective double-blind fashion to IC propranolol (n = 200) or placebo (n = 200) with eptifibatide administered to all the patients. Myocardial isoform of creatine kinase was measured during the first 24 hr and clinical outcomes at 30 days and 1 year. RESULTS: MI after PCI was seen in 21.5% of placebo and 12.5% of propranolol patients (relative risk reduction 0.42; 95%CI 0.09, 0.63; P = 0.016). At 30 days, the composite end point of death, post-procedural MI, urgent target lesion revascularization, or MI after index hospitalization occurred in 22.5% of placebo vs. 13.5% of propranolol patients (risk reduction 0.43; 95%CI 0.08, 0.65; P = 0.018). Similar results were observed at 1 year with adverse outcomes in 21.5% of propranolol and 32.5% of placebo patients (P = 0.01). CONCLUSION: IC propranolol administration with the background Gp IIb/IIIa receptor blockade significantly reduces the incidence of post-PCI MI and improves the short- and long-term clinical outcome when compared with a Gp IIb/IIIa blocker alone.

Endovascular stenting for stenoses in surgically reconstructed brachiocephalic bypass grafts: immediate and midterm outcomes.

PURPOSE: To report the use of endovascular stenting for treatment of patients with symptomatic obstruction of brachiocephalic surgical reconstructions. METHODS: Twenty-two patients (17 men; mean age 65+/-6 years) with 24 symptomatic obstructions of brachiocephalic Dacron bypass grafts (2 aorto-innominate, 9 subclavian-carotid, and 11 carotid-subclavian) were treated with balloon-expandable stents delivered via a percutaneous brachial access or surgical exposure of the common carotid artery. A distal protection device was utilized in the 9 patients with subclavian-carotid bypass grafts. All patients were followed by clinical and Doppler examinations. RESULTS: Procedural success was 100%; 1 (4.5%) patient developed transient intraprocedural aphasia owing to intolerance to the distal protection balloon occlusion. All 22 patients reported complete relief of their presenting symptoms. Over a 29-month follow-up, 3 (13.6%) restenoses were found, but none was due to stent compression. CONCLUSIONS: Stenting for obstructed brachiocephalic reconstructions appears to be a safe, effective, and durable therapeutic strategy.

Two-stage combined endovascular and surgical approach for recurrent thoracoabdominal aortic aneurysm.

PURPOSE: To present a 2-stage combined endovascular and surgical approach for recurrent thoracoabdominal aortic aneurysm (TAAA). CASE REPORT: A 78-year-old man with previous surgical repairs of infrarenal abdominal and descending thoracic aortic aneurysms was referred for dysphagia due to an enlarging 9-cm aneurysm extending from the mid thoracic to the suprarenal aorta. Because no suitable endograft was available, an open repair was attempted, but the presence of a "frozen" chest made the redo procedure extremely difficult. A 2-stage treatment was thus decided upon. First, a retrograde bifurcated bypass graft was implanted from the abdominal aortic graft to the superior mesenteric and celiac arteries. Twenty days later, the TAAA was successfully excluded with a stent-graft, during which spinal fluid drainage was performed to prevent paraplegia. At 6 months, computed tomography showed patency of the endoprosthesis and visceral grafts. At 1 year, the patient remains asymptomatic. CONCLUSIONS: This case illustrates that a 2-stage combined endovascular and surgical approach may be a safe and effective alternative to reoperation for recurrent TAAA.
