RESUMO

There is no treatment for acute aortic dissection (AAD) targeting inflammatory cells. We aimed to identify the new therapeutic targets associated with inflammatory cells. We characterized the specific distribution of myeloid cells of both human type A AAD samples and a murine AAD model generated using angiotensin II (ANGII) and ß-aminopropionitrile (BAPN) by single-cell RNA sequencing (scRNA-seq). We also examined the effect of an anti-interleukin-1ß (IL-1ß) antibody in the murine AAD model. IL1B+ inflammatory macrophages and classical monocytes were increased in human AAD samples. Trajectory analysis demonstrated that IL1B+ inflammatory macrophages differentiated from S100A8/9/12+ classical monocytes uniquely observed in the aorta of AAD. We found increased infiltration of neutrophils and monocytes with the expression of inflammatory cytokines in the aorta and accumulation of inflammatory macrophages before the onset of macroscopic AAD in the murine AAD model. In blocking experiments using an anti-IL-1ß antibody, it improved survival of murine AAD model by preventing elastin degradation. We observed the accumulation of inflammatory macrophages expressing IL-1ß in both human AAD samples and in a murine AAD model. Anti-IL-1ß antibody could improve the mortality rate in mice, suggesting that it may be a treatment option for AAD.

RESUMO

OBJECTIVES: Our goal was to review our surgical experiences in patients with complex pathologies of the aortic arch who have undergone anterolateral thoracotomy with a partial sternotomy (ALPS). METHODS: From October 2019 to November 2023, a total of 23 patients underwent one-stage repairs of complex pathologies of the aortic arch through the ALPS approach. The mean age was 61.9 ± 16.7 years old. The aortic pathologies were as follows: aorta-related infection in 11 (aorto-oesophageal fistula: 4, graft infection: 6, native aortic infection: 1); aortic dissection in 9 including shaggy aorta in 2, non-dissecting aneurysm in 1, and coarctation of the aorta (CoA) in 2. RESULTS: Eighteen patients underwent aortic replacement from either the sinotubular junction or the ascending aorta to the descending aorta; 1 patient underwent it from the aortic root to the descending aorta (redo Bentall procedure and extensive aortic arch replacement); 3 patients underwent it from the aortic arch between the left carotid artery and left subclavian artery to the descending aorta; and 1 patient underwent a descending aortic replacement. Ten patients underwent omentopexy, latissimus dorsi muscle flap installation or both procedures. The hospital mortality rate was 13.0% (3/23). The overall survival and freedom from aortic events were 73.3%±10.2% and 74.1%±10.2%, respectively, at the 3-year follow-up. There was an absence of aorta-related deaths, and no recurrent infections were identified. CONCLUSIONS: The short-term outcomes using the ALPS approach for the treatment of complex pathologies of the aortic arch were acceptable. Further studies will be required to determine the long-term results.

RESUMO

BACKGROUND: Although endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) is widely used worldwide, the fact that it is associated with increased rates of reintervention has been considered a problem. This study aimed to analyze the outcomes of primary open AAA repair and open conversion with explantation of stent grafts after EVAR. METHODS: In this retrospective study, we enrolled 1,120 patients (open repair, n = 664; EVAR, n = 456) who underwent AAA repair at Kobe University from 1999 to 2019. Of the 664 patients who underwent open repair, 121 (patients who underwent primary open repair (POR) as a concomitant procedure and patients with ruptured AAA) were excluded from the study. The outcomes of POR were compared with those of open conversion with explantation of stent grafts. RESULTS: Of the 543 patients who underwent open repair, 513 underwent POR and 30 underwent open conversion with explantation of stent grafts. The operation time for POR was significantly less than that for open conversion with explantation. During surgery, patients who underwent open conversion with explantation required significantly more transfusions of red cell concentrate, fresh frozen plasma, and platelet concentrate than those who underwent POR. Overall, 30 patients who underwent open conversion with explantation required a total of 48 reinterventions before surgery. Hospital mortality rates were 0.7% and 0% in the POR and open conversion with explantation groups, respectively (P = 0.62). Although overall survival at 5 years in the POR group was significantly better than that in the open conversion with explantation group (89.3 ± 1.7% vs. 79.5 ± 9.6%; P = 0.01), there were no significant differences between the 2 groups regarding the freedom from aortic event (hospital death, reintervention, and aortic death). According to the multivariate analysis, open conversion with explantation was not an independent risk factor for late death. There were 20 patients who were hesitant to undergo OCE, although we recommended OCE. In a subgroup analysis, the overall mean cost borne by patients who underwent EVAR was approximately 2.3 times higher compared with that borne by patients who underwent POR. CONCLUSIONS: Although demanding, both early and long-term outcomes of OCE have been favorable in our present study. OCE is highly recommended in patients with persistent sac enlargement after EVAR.

RESUMO

PURPOSE: The present study analyzed the outcomes of our experience with abdominal aortic aneurysm (AAA) repair over 20 years using endovascular aortic repair (EVAR) with commercially available devices or open aortic repair (OAR) and reviewed our surgical strategy for AAA. METHODS: From 1999 to 2019, 1077 patients (659 OAR, 418 EVAR) underwent AAA repair. The OAR and EVAR groups were compared retrospectively, and a propensity matching analysis was performed. RESULTS: EVAR was first introduced in 2008. Our strategy was changed to an EVAR-first strategy in 2010. Beginning in 2018, this EVAR-first strategy was changed to an OAR-first strategy. After propensity matching, the overall survival in the OAR group was significantly better than that in the EVAR group at 10 years (p = 0.006). Two late deaths due to AAA rupture were identified in the EVAR group, although there were no significant differences between the OAR and EVAR groups with regard to the freedom from AAA-related death at 10 years. The rate of freedom from aortic events at 10 years was significantly higher in the OAR group than in the EVAR group (p < 0.0001). CONCLUSION: The rates of freedom from AAA-related death in both the OAR and EVAR groups were favorable, and the rate of freedom from aortic events was significantly lower in the EVAR group than in the OAR group. Close long-term follow-up after EVAR is mandatory.

RESUMO

Traditional vaccinations need to be injected with needles, and since some people have a strong aversion to needles, a needle-free alternative delivery system is important. In this study, we employed ionic liquids (ILs) for transcutaneous delivery of cancer antigen-derived peptides to obtain anticancer therapeutic effects in a needle-free manner. ILs successfully increased the in vitro skin permeability of a peptide from Wilms tumor 1 (WT1), one of the more promising cancer antigens, plus or minus an adjuvant, resiquimod (R848), a toll-like receptor 7 agonist. In vivo studies demonstrated that concomitant transcutaneous delivery of WT1 peptide and R848 by ILs induced WT1-specific cytotoxic T lymphocyte (CTL) in mice, resulting in tumor growth inhibition in Lewis lung carcinoma-bearing mice. Interestingly, administrating R848 in ILs before WT1 peptides in ILs increased tumor growth inhibition effects compared to co-administration of both. We found that the prior application of R848 increased the infiltration of leukocytes in the skin and that subsequent delivery of WT1 peptides was more likely to induce WT1-specific CTL. Furthermore, sequential immunization with IL-based formulations was applicable to different types of peptides and cancer models without induction of skin irritation. IL-based transcutaneous delivery of cancer antigen-derived peptides and adjuvants, either alone or together, could be a novel approach to needle-free cancer therapeutic vaccines.

RESUMO

BACKGROUND: Abdominal aortic aneurysm (AAA) is a life-threatening cardiovascular disease characterized by dilated abdominal aorta. Immune cells have been shown to contribute to the development of AAA, and that the gut microbiota is associated with numerous diseases, including cardiovascular diseases, by regulating immune systems or metabolic pathways of the host. However, the interaction between the gut microbiota and AAA remains unknown. METHODS: Apolipoprotein E-deficient male mice were fed a high-cholesterol diet and divided into three groups: the control group was maintained under normal water (control group), the oral AVNM group was maintained under drinking water supplemented with ampicillin, vancomycin, neomycin, and metronidazole, and the i.p. AVNM group was injected AVNM intraperitoneally. After 1 week of pretreatment with antibiotics, these mice were administrated Ang II via subcutaneous osmotic pumps for 4 weeks and euthanized to evaluate AAA formation. RESULTS: Depletion of gut microbiota by oral AVNM ameliorated the incidence of AAAs (control group: 58.9% versus oral AVNM group: 28.6% versus i.p. AVNM group: 75.0%, P = 0.0005) and prevented death due to ruptured aneurysms (control group: 11% versus oral AVNM group: 0% versus i.p. AVNM group: 15%). Oral AVNM suppressed monocyte storage in the spleen, but not in other organs. Despite possessing a higher level of cholesterol, recruitment of monocytes into the suprarenal aorta was suppressed in the oral AVNM group. In AVNM drinking mice, NOD1 ligand, a kind of PRR ligands, increased the development of AAAs and accumulation of macrophages in the aortae. CONCLUSIONS: The gut microbiota plays a critical role in AAA formation. Therefore, regulation of the microbiota or the immune system can be a therapeutic approach for AAA.

RESUMO

A 74-year-old man who had been receiving antibiotic treatment for meningitis was transferred to our hospital because of a sudden decrease in lower limb blood pressure. Computed tomography revealed a type B aortic dissection with obstruction of the abdominal aorta. Furthermore, transesophageal echocardiography revealed a large vegetation on the proximal entry tear of the descending aorta. We performed successful emergency descending and abdominal aorta replacement, which prevented complications from intraoperative organ malperfusion. In the present report, we have described an effective treatment for lower limb malperfusion complicated by a combination of chronic aortic dissection and bacteremia.

RESUMO

OBJECTIVES: The goal of this study was to evaluate the fate of the downstream aorta following total arch replacement. METHODS: Between October 1999 and March 2018, a total of 740 patients underwent total arch replacement. After excluding connective tissue disease, previous descending or thoracoabdominal aortic surgery, patients without adequate preoperative images or operative mortality, late outcomes consisting of additional surgery for distal dilation and distal aortic events were evaluated in 623 survivors (240 aortic dissections, including 139 patients with acute dissection and 383 with a non-dissection aneurysm). The mean follow-up was 5.0 ± 4.0 years. RESULTS: The mean preoperative maximum diameter of the descending aorta was 36.9 ± 8.0 mm. An elephant trunk was inserted in 232 patients, including 183 patients with aortic dissection. Freedom from additional surgery for distal dilation was 88.5% at 5 years and 80.2% at 10 years. Freedom from distal aortic events was 81.9% at 5 years and 70.5% at 10 years. Multivariable regression analysis demonstrated that the preoperative diameter of the descending aorta was a significant risk factor for unfavourable distal aortic events. Computed tomography evaluation demonstrated a significant increase in the descending aortic diameter over time (P < 0.001). Positive aortic remodelling was observed in the proximal descending (P < 0.001) to mid-descending (P < 0.001) aorta exclusively in patients with acute aortic dissection. CONCLUSIONS: The diameter of the descending aorta increased significantly after total arch replacement, particularly in the distal descending aorta. The preoperative descending aortic diameter portended a significant risk for unfavourable distal aortic events.

RESUMO

Spinal cord ischemia (SCI) after endovascular abdominal aortic aneurysm repair is a rare but devastating complication. Occlusion of the artery of Adamkiewicz or feeders to the collateral network for spinal cord circulation (such as the subclavian, intercostal, lumbar, and internal iliac arteries) is associated with the onset of SCI. We present a case of monoplegia owing to SCI after elective endovascular abdominal aortic aneurysm repair with coil embolization of the left internal iliac artery in an elderly patient with a history of arteriosclerosis obliterans and aortic dissection, preoperatively occluding multiple intercostal arteries and the right internal iliac artery.

RESUMO

The effect of acute kidney injury (AKI) on mid-term outcomes following thoracoabdominal aortic aneurysm (TAAA) repair is not well known. We hypothesized that postoperative AKI would reduce mid-term survival and aimed to analyze the effect of AKI on mid-term outcomes after TAAA repair. This retrospective study identified 294 consecutive TAAA repairs at Kobe University Hospital from October 1999 to March 2019. Patients with preexisting end-stage renal disease that required hemodialysis (n = 11) and patients who died intraoperatively (n = 2) were excluded. Finally, 281 patients were analyzed. AKI was defined according to Kidney Disease: Improving Global Outcomes guidelines (KDIGO) classification. Of the 281 patients, 178 (63.3%) developed AKI, of which 98 (34.9%) had mild, 34 (12.1%) had moderate, and 46 (16.4%) had severe AKI. Twenty-six patients (12.8%) required renal replacement therapy after surgery. Twenty-three in-hospital deaths (8.2%) were recorded, including 2 (0.7%) without AKI, 0 (0%) with mild AKI, 1 (0.4%) with moderate AKI, and 20 (7.1%) with severe AKI (p < .001). The 4-year survival was 91.9 ± 3.0% for no AKI, 91.3 ± 3.2% for mild AKI, 72.4 ± 8.5% for moderate AKI and 32.6 ± 7.4% for severe AKI (p < .001). Multivariable Cox-hazard regression analysis demonstrated that moderate and severe AKI, older age and emergency surgery were significant risk factors for mid-term survival. In patients undergoing TAAA repair, severe AKI was associated with an increase in in-hospital mortality and both moderate and severe AKI were negatively associated with mid-term survival. Preventing moderate/severe AKI may improve mid-term survival after TAAA repair.

RESUMO

An impending paradoxical embolism (IPDE) is seldom observed in clinical practice. We report a case of IPDE in a 67-year-old female with severe dyspnea and hypotension, which was detected and successfully treated with emergent cardiac surgery. The optimal treatment is still controversial. We believe that emergent surgery always should be considered in patients with IPDE. .

RESUMO

OBJECTIVES: Total arch replacement( TAR) is used to be a complicated and quite invasive aortic procedure. To perform TAR safely and effectively under all circumstances, we have constructed standardization of the procedures of TAR. The aim of this study is to analyze the impact of surgeons' experience on surgical outcome of TAR to evaluate our standardization. METHODS: From January 2008 to December 2020, 346 consecutive patients (mean age 73.6±10.2) underwent elective TAR through a median sternotomy at our institute. TAR was performed by three types of surgeon classified by their experience( A:over 20 years, B:15~20 years, C:under 15 years). The surgical outcomes were examined. Our standard approach include( 1) meticulous selection of arterial cannulation site and type of arterial cannula;(2) antegrade selective cerebral perfusion;(3) maintenance of minimal tympanic temperature between 20 ℃ and 23 ℃;(4) early rewarming just after distal anastomosis;(5) maintaining fluid balance below 1,000 ml during cardiopulmonary bypass. RESULTS: The operative cases were 227 in A, 86 in B and 33 in C. Surgeon A operated more complicated TAR with higher operative risk compared with B and C. The hospital mortality and major complication rate was not significant difference among surgeons( hospital mortality A:3.5%, B:2.3%, C:3.0%). Multivariate analysis showed the surgeons' experience was not associated with hospital mortality and major complications. Long-term outcomes were also compatible among three groups. CONCLUSIONS: Our standardization for TAR seemed to be an useful approach to eliminate the impact of surgeon experience on surgical outcomes if the type of surgeon was appropriately selected according to the level of operative difficulty.

RESUMO

BACKGROUND: The aim of this study was to evaluate the fate of the preserved aortic root after supracoronary aortic replacement for acute type A aortic dissection. METHODS: Between October 1999 and March 2018, 339 patients underwent supracoronary aortic replacement for acute type A aortic dissection at our institution. Late outcomes were evaluated, including overall survival, aortic-related death, and aortic root-related reoperation. The median follow-up was 3.7 years (1.4-8.4 years). RESULTS: Operative mortality was 46 patients (13.6%). The cumulative incidences at 5 years for aortic root-related reoperation, aortic-related death, and non-aortic related death were 2.5%, 14.5% and 12.4%, respectively. Multivariable Cox hazard regression analysis demonstrated greater sinus of Valsalva diameter and number of commissural detachments to be significant risk factors for a composite outcome consisting of aortic-related death or aortic root-related reoperation. Mixed-effects regression demonstrated that sinus of Valsalva diameter significantly increased with time (P < .001), and aortic regurgitation significantly worsened (P < .001). CONCLUSIONS: Sinus of Valsalva diameter and commissural detachment were independent predictors of unfavorable outcomes after supracoronary aortic replacement. Close follow-up is particularly necessary for these patients, and aortic root replacement at the time of initial operation may lead to more favorable late outcomes.

RESUMO

It is essential to establish cardiopulmonary bypass by percutaneous insertion of a large-bore catheter via both the femoral vein and internal jugular vein (IJV) for minimally invasive cardiac surgery (MICS). Complications associated with IJV catheterization during MICS have been reported in the literature; however, vascular injury of the subclavian artery (SCA) is rare. We herein present a rare case in which an iatrogenic arteriovenous fistula (AVF) between the right SCA and IJV after MICS was successfully treated by endovascular coil embolization. A 61-year-old man who had undergone mitral valve repair by MICS 10 months before presentation was referred because of pulsatile cervical bruit and tinnitus. Radiographic examination revealed a right SCA pseudoaneurysm associated with an AVF located between the right common carotid artery and vertebral artery. The AVF was completely occluded with detachable coils using a double-catheter technique to avoid coil migration into the IJV. This technique has been used to treat high-flow or complex AVFs, including pulmonary and renal AVFs. As shown in the present case, it is also useful to treat an iatrogenic AVF between the SCA and IJV.

RESUMO

OBJECTIVES: Valve repair for aortic insufficiency (AI) requires a tailored surgical approach determined by the leaflet and aortic disease. In this study, we used a repair-oriented system for the classification of AI, and we elucidated long-term outcomes of aortic root reimplantation with this classification system. METHODS: From 1999 to 2018, a total of 197 patients underwent elective reimplantation (mean age: 52.7 ± 17.7 years; 80% male). The aortic valve was tricuspid in 143 patients, bicuspid in 51 patients and quadricuspid in 3 patients. A total of 93 patients had type I AI (aortic dilatation), 57 patients had type II AI (cusp prolapse) and 47 patients had type III AI (restrictive). In total, 104 of the 264 patients (39%) had more than 1 identified mechanism. RESULTS: In-hospital mortality was 0.5% (1/197). Mid-term follow-up (mean follow-up duration: 5.5 years) revealed a late mortality rate of 4.2% (9/197). Aortic valve reoperation was performed on 16 patients (8.0%). Rates of freedom from aortic valve replacement and freedom from aortic valve-related events at 10 years of follow-up were 87.0 ± 4.0% and 60.6 ± 6.0%, respectively; patients with type Ib AI (98.3 ± 1.7%; 80.7 ± 7.5%) had better outcomes than patients with type III AI (59.6 ± 15.6%; 42.2 ± 13.1%, P = 0.01). In patients with types II and III AI who had bicuspid aortic valves, rates of freedom from aortic valve-related events at 5 years of follow-up were 95.2 ± 4.7% and 71.7 ± 9.1%, respectively (P = 0.03). CONCLUSIONS: This repair-oriented system for classifying AI could help to predict the durable aortic valve repair techniques. Patient selection according to the classification is particularly important for long-term durability. CLINICAL TRIAL REGISTRATION NUMBER: B190050.

RESUMO

BACKGROUND: The aim of this study was to evaluate the impact of diffuse aortic atherosclerosis-related thrombosis, or "shaggy aorta" on the outcomes of open thoracoabdominal aortic aneurysm repair (TAAA). METHODS: From October 1999 to March 2018, 251 patients underwent open TAAA repair using segmental-staged aortic clamping. Twenty-eight patients (11.2%) received emergent or urgent operations. Patients were classified into 3 groups: dissection aneurysm (139 patients, 55.4%), degenerative aneurysm without shaggy aorta (76 patients, 30.3%), and degenerative aneurysm with shaggy aorta (36 patients, 14.3%). Shaggy aorta was assessed using enhanced computed tomography and defined as patients with atheroma thickness ≥5 mm with irregular atheroma surface. Mean follow-up was 4.3 ± 4.1 years. RESULTS: Operative mortality was 8% (20 patients) and spinal cord injury occurred in 25 patients (10.0%), 16 of whom (6.4%) had permanent neurologic dysfunction. Operative mortality was significantly worse in patients with shaggy aorta (dissection: 2.2%, non-shaggy: 6.6%, and shaggy: 33.3%, P < .001) and shaggy aorta was a significant risk factor for spinal cord injury (dissection: 7.2%, non-shaggy: 6.6%, and shaggy: 27.8%, P < .003). Multivariable analysis demonstrated that shaggy aorta was a significant risk factor for composite outcome consisted of operative mortality, spinal cord injury, and acute renal failure (odds ratio, 4.78; 95% confidence interval, 1.91-12.3, P < .001). CONCLUSIONS: Preoperative enhanced computed tomography assessment of shaggy aorta could predict high-risk patients for open TAAA repair.

RESUMO

BACKGROUND: This study evaluates our 18-year experience of total arch replacement in the octogenarian and nonagenarian population. METHODS: Between October 1999 and March 2018, a total of 740 patients underwent total arch replacement at our institution. A total of 139 patients were aged 80 years or more (83.1 ± 2.8 years), and 601 patients were aged less than 80 years (66.9 ± 11.3 years). Early and late outcomes were compared between the groups. RESULTS: In the group aged 80 years or more, operative mortality occurred in 12 patients (8.6%) and significantly improved over time (P = .010). Operative mortality was significantly higher in the group aged 80 years or more (P = .033) when compared with the group aged less than 80 years (4.0%). Regarding postoperative complications, deep sternal wound infection, pneumonia, and tracheostomy occurred in significantly more patients in the group aged 80 years or more. In the group aged 80 years or more, there were 52 late deaths, with 4 aortic-related deaths. Overall survival was 55.4% ± 5.0% at 5 years and 32.2% ± 6.1% at 8 years. Multivariable Cox-hazard regression analysis demonstrated that chronic kidney disease, nonelective surgery, and concurrent procedures were significant risk factors for overall survival in the group aged 80 years or more. Cumulative incidence for reoperation was significantly lower in the group aged 80 years or more (8.7% at 5 years) compared with the group aged less than 80 years (14.2% at 5 years). CONCLUSIONS: Total arch replacement was performed with an acceptable overall survival in octogenarians and nonagenarians, although operative mortality was higher than in younger patients. However, older patients had a lesser burden of reoperation compared with younger patients.

RESUMO

A 65 year-old man was diagnosed with congestive heart failure secondary to severe mitral regurgitation resulting from a parachute-like asymmetrical mitral valve. We performed mitral annuloplasty and triangular resection of the thick tissue. The postoperative course was uneventful with no recurrence of mitral regurgitation.

RESUMO

OBJECTIVE: We present our open surgical strategies for staged replacement of the thoracic and thoracoabdominal aorta in patients with Marfan syndrome. METHODS: Between October 1999 and December 2017, 82 patients with Marfan syndrome underwent 118 aortic repairs. We divided the aorta into 4 segments for categorization: (1) the aortic root, (2) aortic arch, (3) descending thoracic, and (4) abdominal aorta. Procedures were categorized according to the types of surgery. Staged repair was defined as a subsequent operation on a different segment of the aorta after initial repair (n = 111, 94.1%), and reoperation was defined as an operation on the same segment (n = 7, 5.9%). RESULTS: The mean age at initial operation was 41.7 ± 14.9 years. Staged repairs included aortic root replacement (n = 42, 36%), total arch replacement (n = 11, 9.3%), combined aortic root and total arch replacement (n = 13, 11%), descending aorta replacement (n = 4, 3.4%), thoracoabdominal aortic repair (n = 36, 31%), and extensive arch-descending or thoracoabdominal repair (n = 5, 4.2%). Four patients received 3 staged repairs. Operative mortality was 0.8% (1/118). Stroke occurred in 1.7% (2/118), and spinal cord injury occurred in 1.7% (2/117). Overall survival was 95.8 ± 2.4% at 10-years. Twenty-four patients underwent replacement of the whole aorta after 2.5 ± 3.8 years following initial repair. CONCLUSIONS: Our strategies for staged replacement of the thoracic and thoracoabdominal aorta in patients with Marfan syndrome resulted in excellent early- and long-term outcomes.
