RESUMO
BACKGROUND: Epidemiological data on ruptured aortic aneurysms from large-scale studies are scarce. The aims of this study were to: clarify the clinical course of ruptured aortic aneurysms; identify aneurysm site-specific therapies and outcomes; and determine the clinical course of patients receiving conservative therapy.MethodsâandâResults: Using the Tokyo Acute Aortic Super Network database, we retrospectively analyzed 544 patients (mean [±SD] age 78±10 years; 70% male) with ruptured non-dissecting aortic aneurysms (AAs) after excluding those with impending rupture. Patient characteristics, status on admission, therapeutic strategy, and outcomes were evaluated. Shock or pulselessness on admission were observed in 45% of all patients. Conservative therapy, endovascular therapy (EVT), and open surgery (OS) accounted for 32%, 23%, and 42% of cases, respectively, with corresponding mortality rates of 93%, 30%, and 29%. The overall in-hospital mortality rate was 50%. The prevalence of pulselessness was highest (48%) in the ruptured ascending AA group, and in-hospital mortality was the highest (70%) in the ruptured thoracoabdominal AA group. Multivariable logistic regression analysis indicated in-hospital mortality was positively associated with pulselessness (odds ratio [OR] 10.12; 95% confidence interval [CI] 4.09-25.07), and negatively associated with invasive therapy (EVT and OS; OR 0.11; 95% CI 0.06-0.20). CONCLUSIONS: The outcomes of ruptured AAs remain poor; emergency invasive therapy is essential to save lives, although it remains challenging to reduce the risk of death.
RESUMO
BACKGROUND: An increased prevalence of thoracic aortic aneurysms (TAA) has been demonstrated in patients with simple renal cysts (SRC); patients with SRC have a less elastic aortic wall than those without SRC. The purpose of this study was to evaluate aneurysm sac shrinkage after thoracic endovascular aortic repair (TEVAR) for true TAA in patients with and without SRC. METHODS: One hundred three patients with true aneurysms of the thoracic aorta who underwent TEVAR at our university hospital from November 2013 to December 2021 were included in this study. Aneurysm sac size was compared between that on baseline preoperative computed tomography and that on postoperative computed tomography scans at 1 year. A change in aneurysm sac size ≥5 mm was considered to be significant, whether due to expansion or shrinkage. RESULTS: The patients were divided into two groups: those with SRC (46 patients [45%]) and those without SRC (57 patients [55%]). At 1 year, there was a significant difference in the proportion of aneurysm sac shrinkage between patients with SRC and those without SRC (23.9% vs 59.6%; P < .001). Patients with SRC showed significantly less aneurysm sac shrinkage than those without SRC (-1.8 ± 5.6 mm vs -5.1 ± 6.6 mm; P = .009). Univariable and multivariable analyses showed that the initial sac diameter (odds ratio, 1.08; 95% confidence interval, 1.03-1.14; P = .002) and the presence of SRC (odds ratio, 0.15; 95% confidence interval, 0.06-0.40; P < .001) were positively and negatively associated with aneurysm sac shrinkage after TEVAR, respectively. CONCLUSIONS: The presence of a SRC was independently associated with failure of aneurysm sac shrinkage after TEVAR for true TAA. This suggests that the presence of a SRC may be a predictor for the failure of aneurysm sac shrinkage after TEVAR.

PURPOSE: To investigate the incidence of postoperative cerebral infarction after curative lobectomy, its association with the type of lobectomy, and how postoperative new-onset arrhythmia contributes to postoperative cerebral infarction. METHODS: The subjects of this analysis were 77,060 patients who underwent curative lobectomy for lung cancer between 2016 and 2018 according to the National Clinical Database. Incidences of postoperative cerebral infarction and postoperative new-onset arrhythmia were analyzed. Moreover, mediation analysis was performed to evaluate the causal pathway between postoperative new-onset arrhythmia and postoperative cerebral infarction. RESULTS: Postoperative cerebral infarction occurred in 110 (0.7%) patients after left upper lobectomy and in 85 (0.7%) patients after left lower lobectomy. Left upper lobectomy and left lower lobectomy were associated with a higher likelihood of postoperative cerebral infarction than right lower lobectomy. Left upper lobectomy was the strongest independent predictor of postoperative new-onset arrhythmia. However, in the mediation analysis, the odds ratio for cerebral infarction did not change after the addition of the factor of postoperative new-onset arrhythmia. CONCLUSION: Cerebral infarction occurred significantly more often not only after left upper lobectomy, but also after left lower lobectomy. Postoperative new-onset arrhythmia was less likely to be related to cerebral infarction after left upper lobectomy.

OBJECTIVES: This study aimed to develop clinical guidelines for the management of vascular Behçet's disease (BD) by the Behçet's Disease Research Committee of the Ministry of Health, Labour and Welfare of the Japanese Government. METHODS: A task force proposed clinical questions (CQs) concerning vascular BD based on a literature search. After screening, draft recommendations were developed for each CQ and brushed up in three blinded Delphi rounds, leading to the final recommendations. RESULTS: This study provides recommendations for 17 CQs concerning diagnosis and differential diagnoses, assessment of disease activity, and treatment. The guidelines recommend immunosuppressive treatments, for both arterial and venous involvement with active inflammation. Anticoagulation is also recommended for deep vein thrombosis except in high-risk patients. Surgical and endovascular therapies can be optional, particularly in patients with urgent arterial lesions undergoing immunosuppression. In addition, two sets of algorithms for diagnosis and treatment are shown for arterial and venous involvement. CONCLUSIONS: These recommendations are expected to serve as useful tools in the daily clinical practice of BD.

PURPOSE: The factors associated with aneurysm sac shrinkage after endovascular aneurysm repair (EVAR) are not well established. As inflammation is implicated in aneurysm pathophysiology, we hypothesized that high-sensitivity C-reactive protein (hsCRP) was associated with aneurysm sac shrinkage after EVAR and compared the preoperative level of hsCRP between patients with and without postoperative aneurysm sac shrinkage after EVAR. METHODS: From November 2013 to April 2019, 143 patients undergoing EVAR using Gore C3 Excluder (W. L. Gore & Associates, Inc, Flagstaff, Arizona) at our university hospital were included in this study. Aneurysm sac size was compared between that on baseline preoperative computed tomography (CT) and that on postoperative CT scans. A change in aneurysm sac size ≥5 mm was considered to be significant, whether due to enlargement or shrinkage. RESULTS: Aneurysm sac size showed a significant decrease from 50.6 ± 9.8 mm to 47.1 ± 10.3 mm at 1 year. At 1 year postoperatively, aneurysm sac shrinkage (≥5 mm) was observed in 48 patients (34%), a stable aneurysm sac was noted in 93 patients (65%), and aneurysm sac enlargement was noted in 2 patients (1.4%). The mean preoperative hsCRP was 0.33 ± 0.54 mg/dL. Univariable analysis showed that preoperative hsCRP (p=0.029) and the presence of a renal cyst (p=0.002) were associated with aneurysm sac shrinkage. Multivariable analysis showed that preoperative hsCRP [>0.19mg/dL] (odds ratio [OR] = 0.22; 95% confidence interval [CI] = 0.05-0.96; p=0.042), and the presence of a renal cyst (OR = 0.31; 95% CI = 0.15-0.67; p=0.002) were independent risk factors for aneurysm sac shrinkage after EVAR. CONCLUSIONS: The level of preoperative hsCRP was independently associated with aneurysm sac shrinkage after EVAR in patients with abdominal aortic aneurysms. These data suggest that the high level of hsCRP can be a negative predictor for aneurysm sac shrinkage after EVAR.

PURPOSES: A retrospective analysis was performed to compare the pathological findings and aortic root Z-score in patients with and without connective tissue disease (CTD). METHODS: Twenty-two patients {47.5 [15-85] years old, 18 males} underwent surgery for aortic root dilatation without aortic dissection: 10 {40 [16-59] years old} with CTD and 12 {57.5 [15-85] years old} without CTD (non-CTD; p = 0.049). Systemic hypertension (p = 0.043) and the degree of preoperative aortic regurgitation (p = 0.017) were higher in the non-CTD patients than in the CTD patients. RESULTS: The diameters of the sinotubular junction (STJ) (p = 0.048) and ascending aorta (Asc.Ao.) (p = 0.020) and the Z-scores of the STJ (p = 0.027) and Asc.Ao. (p = 0.009) were significantly higher in the non-CTD patients than in the CTD patients. The degree of translamellar mucoid extracellular matrix accumulation (T-MEMA) of the Asc.Ao. was significantly higher in the non-CTD patients than in the CTD patients (p = 0.037) and was significantly correlated with the Z-scores of the aorta (R = 0.746, p < 0.01 in the sinus of Valsalva and R = 0.382, p = 0.031 in the Asc.Ao.), although there was no significant correlation between the diameter of the STJ and that of Asc.Ao. CONCLUSIONS: In non-CTD patients, not only the aortic root but also Asc.Ao. tended to dilate with age, and a significant correlation between the Z-scores of the aorta root and the Asc.Ao. and the degrees of T-MEMA was observed.

PURPOSES: To perform successful aortic valve plasty (AVP) and valve-sparing root replacement (VSRR), a sufficient understanding of the aortic root and cusp geometry is required. Several key parameters of the aortic root and cusp geometry were, therefore, measured intraoperatively. METHODS: Forty-nine patients (63.1 ± 16.6 y.o., 40 males) were measured during the surgeries. The patients were divided into 3 groups; including patients with no or mild aortic valve regurgitation (AR) (n = 13), moderate AR (n = 18), and severe AR (n = 18). RESULTS: There were no significant differences in the body surface area (1.72 ± 0.19 m2) among the 3 groups (p = 0.858). The effective height (EH) and geometric height (GH) of right coronary cusp were smaller than those of the others (EH: p = 0.068, GH: p < 0.01). The insertion line length (ILL) and free margin length (FML) of each leaflet tended to be significantly longer according to the AR grade(ILL: p < 0.01, FML: p < 0.01). The FML/AVJ ratios were significantly different (p < 0.01). The FML/ILL ratios were constant with the ratio of 0.88 ± 0.1(p = 0.624). CONCLUSIONS: Although the ILL and FML tended to increase with the AR grade, the FML/ILL ratio remained constant. For successful AVP and VSRR, adequately maintaining the FML/ILL ratio is necessary to prevent remarkable cusp prolapse while also preserving its favorable cusp motion.

Redo or repetitive surgeries for residual distal dissection after the limited proximal aortic repair for Stanford type A acute aortic dissection remains challenging. Depending on targeted aortic segments, the strategy including a median or lateral approach and one or two-staged repairs would be determined with careful consideration for patient's age and conditions of the brain, heart, lung, liver, and kidney. Given the aortic arch involved, for young and low-risk patients, an aggressive one-stage repair of the entire arch to descending aorta through a left thoracotomy is attempted. In particular, with our left antero-axillary approach, it would be much easier with a better surgical field from the ascending aorta to the descending/thoracoabdominal aortic segments. Meanwhile, two-staged repairs are more beneficial for elderly higher-risk patients, which consists of the first total arch replacement (TAR) with elephant trunk (ET) through a median sternotomy followed secondly by an open descending/thoracoabdominal aortic repair through a left thoracotomy or by less-invasive thoracic endovascular aortic repair. In additions, TAR with a frozen ET (FET) has been a new option for downstream aortic remodeling. Consequently, in the initial repair, TAR with FET or ET has been more aggressively performed to prevent such troublesome behaviors of the residual aortic dissection.

OBJECTIVE: Patients with abdominal aortic aneurysm (AAA) frequently have simple renal cyst (SRC), a common manifestation of connective tissue degeneration. This study aimed to determine whether SRC is a risk factor for failure of sac shrinkage after endovascular aneurysm repair (EVAR). METHODS: Between October 2013 and May 2017, there were 155 consecutive patients with an infrarenal AAA or a common iliac artery aneurysm who underwent EVAR with the GORE C3 Excluder (W. L. Gore & Associates, Flagstaff, Ariz) at Tokyo Medical University Hospital. All these patients were registered in a prospectively maintained database. Any kidney lesion >5 mm in diameter, with no evidence of contrast enhancement or septation and with low attenuation, was defined as SRC. A change in sac size of >5 mm from baseline was considered significant. The patients were divided into those with SRC and those without SRC, and sac shrinkage at 1 year and 2 years was compared. The presence of SRC was assessed with respect to being a risk factor for failure of sac shrinkage at 1 year using univariate and multivariable logistic regression analysis. RESULTS: The patients were divided into two groups: those with SRC (92 patients [59.0%]) and those without SRC (63 patients [41.0%]). At 1 year and 2 years, significant differences were observed in the proportion of sac shrinkage between patients with SRC and those without SRC (19.2% vs 42.4% [P = .003] and 19.6% vs 53.3% [P = .001], respectively). Patients with SRC showed significantly less sac shrinkage than those without SRC at 1 year and 2 years (-2.0 ± 5.5 mm vs -4.4 ± 6.2 mm [P = .002] and -1.8 ± 6.3 mm vs -6.4 ± 8.6 mm [P = .005], respectively). Multivariable analysis demonstrated that SRC (odds ratio, 0.28; 95% confidence interval, 0.12-0.63; P = .002) and initial sac size (odds ratio, 1.05; 95% confidence interval, 1.01-1.09; P = .027) were positive and negative risk factors for sac shrinkage, respectively. CONCLUSIONS: The presence of SRC is a risk factor for failure of sac shrinkage after EVAR. This suggests that AAA in patients with SRC has a more degenerated wall than in those without SRC. The property of the aneurysm wall may be associated with sac shrinkage after EVAR.

OBJECTIVE: This study aimed to assess the sex differences in clinical presentation and outcomes of Japanese patients with ruptured aortic aneurysm (rAA) using a large nationwide claims-based database in Japan. METHODS: We identified patients hospitalized in certified teaching hospitals in Japan with rAA between April 1, 2012, and March 31, 2015. Patients' characteristics and in-hospital outcomes were compared between men and women. The Barthel index was used for evaluating functional status at discharge by examining the ability to perform basic daily activities. RESULTS: Of 7086 eligible patients, 32.3% (2291/7086) were women. Women were older than men (81.9 years vs 76.1 years; P < .001), had higher prevalence of coma at admission (33.2% vs 25.2%; P < .001), and were less likely to undergo emergency operation including endovascular aneurysm repair (35.7% vs 51.1%; P < .001). The unadjusted mortality rate (62.5% vs 52.0%; P < .001) and Barthel index at discharge (78.7 vs 86.1; P < .001) were significantly worse in women than in men. However, multilevel mixed-effect logistic regression analyses showed that female sex itself was not an independent predictor for in-hospital death (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.78-1.04; P = .17). Older age, coma at admission, and vasopressor use were detected as independent predictors for in-hospital death. The same results were confirmed for each rupture site. Stratified analyses showed that older women (threshold, 80 years; OR, 0.81; 95% CI, 0.66-0.98; P = .028) and those who underwent emergency operation (OR, 0.75; 95% CI, 0.61-0.93; P = .009) showed significantly better outcomes than men. CONCLUSIONS: In a univariate analysis, female patients with rAA showed worse mortality than men because of their older age, more severe clinical presentation, and low emergency operation rate. However, after adjustment for covariates, female sex itself was not associated with increased mortality.

OBJECTIVE: This study aimed to clarify the impact of endovascular aneurysm repair (EVAR) on clinical outcomes in Japanese patients of advanced age with ruptured abdominal aortic aneurysm (rAAA). METHODS: This was a national registry based retrospective comparative study, using data from the Japanese Registry Of All cardiac and vascular Diseases-Diagnostic Procedure Combination (JROAD-DPC), a nationwide claim based database from more than 600 hospitals. Patients admitted with rAAA between April 1, 2012, and March 31, 2015 were included in the study. Patient characteristics, management, and outcomes were compared between the elderly (aged ≥ 80 y) and the less old. The primary endpoint was in hospital mortality; the secondary endpoint was the functional status at discharge. RESULTS: Of 3 969 eligible patients, 49.9% were categorised as elderly. Elderly patients had a higher prevalence of female gender (41.8% vs. 17.0%, p < .001) and disturbance of consciousness on admission (28.6% vs. 20.7%, p < .001). They were less likely to undergo open surgical repair (31.6% vs. 56.7%, p < .001), although EVAR was performed similarly in both groups (13.7% vs. 14.8%, p = .33). The unadjusted mortality rate (61.8% vs. 37.6%, p < .001) and mean Barthel index at discharge (73.0 vs. 91.8, p < .001) were statistically significantly worse in the elderly. Multilevel mixed effect logistic regression analyses showed that old age was detected as an independent predictor of in hospital death (odds ratio 2.75; 95% confidence interval, 2.39-3.17; p < .001). However, for patients who received EVAR, old age was not statistically significant (odds ratio 1.13; 95% confidence interval, 0.77-1.66; p = .53). CONCLUSION: Elderly patients with rAAA were less likely to be offered open surgical repair, and the mortality among those who received surgery was high. However, for the small subgroup of elderly patients currently selected for EVAR there was a favourable outcome. The further implementation of EVAR for rAAA in Japan, especially for elderly patients with suitable anatomy, may be justified.

OBJECTIVE: This study compared outcomes after endovascular aneurysm repair (ER) and open surgical repair (OR) of ruptured descending thoracic aortic aneurysms (rDTAA) and ruptured abdominal aortic aneurysms (rAAA) through a nationwide analysis performed in Japan. METHODS: This was a national registry based retrospective comparative study using data from the Japanese Registry of all Cardiac and Vascular Diseases Diagnostic Procedure Combination (JROAD-DPC) database, a nationwide claim based database from more than 600 hospitals. Patients admitted to certificated teaching hospitals with rDTAA and rAAA and treated by either ER or OR between 1 April 2012 and 31 March 2015 were identified. A propensity score matched analysis was performed to compare ER and OR. RESULTS: About 40% of the total cohort (n = 8,302) were managed conservatively for various reasons, including limited options in primary care facilities in certain areas. In total, 983 patients had rDTAA (OR = 511; ER = 472) and 2,320 (OR = 1,754; ER = 566) had rAAA. Altogether, 604 and 1,080 patients were matched with rDTAA and rAAA, respectively. Compared with OR, ER was associated with significantly better in hospital mortality in patients with rDTAA (ER = 22.5%; OR = 29.8% [p < .001]) and similar mortality for those with rAAA (ER = 25.7%; OR = 24.3% [p = .57]). ER involved significantly shorter hospital stays for rDTAA (ER = 25.5; OR = 32 days [p < .001]) and rAAA (ER = 16; OR = 21 days [p < .001]). The median Barthel Index at discharge was ≥75/100 for all groups, and there were no differences between ER and OR. Total medical costs were significantly lower for ER for rDTAA (ER = ¥6.47 million, OR = ¥7.28 million [p < .001]) but were higher for rAAA (ER = ¥4.65 million; OR = ¥3.43 million [p < .001]). CONCLUSION: A Japanese nationwide observational study showed that in hospital outcomes for ER vs. OR were more favourable for rDTAA and comparable for rAAA. ER resulted in an equivalently favourable functional status at discharge and significantly shorter hospital stays.

Acute aortic dissection (AAD) cases are thought to have high blood pressure (BP) on admission; however, little data are available on BP prior to admission. The purpose of this study was to investigate systolic blood pressure (SBP) very early after symptom onset and before hospital transfer in patients with AAD to determine whether SBPs were high, and also whether SBPs were higher or lower compared with SBPs at hospital admission. We obtained results using three-year data derived from the Tokyo Acute Aortic Super Network Database. First, we selected 830 patients with AAD for which the "duration from symptom onset to first medical contact by ambulance crews" (SO-FMC) was within 60 min. We examined the SBPs of such patients. Next, we selected 222 patients with AAD whose SBPs were measured both at FMC, within 15 min after symptom onset, and at hospital admission, and compared SBPs at FMC with those at hospital admission. Among types A (n = 190) and B (n = 117), in patients with an SO-FMC ≤ 15 min, the median SBP was 100 mmHg and 178 mmHg (p < 0.001), respectively; 9% and 50% (p < 0.001) of such patients, respectively, exhibited an SBP ≥ 180 mmHg; and 43% and 10% (p < 0.001) of such patients, respectively, had an SBP < 90 mmHg. Of patients with types A (n = 124) and B (n = 98) AAD whose SBPs were measured both at FMC, within 15 min after symptom onset, and at hospital admission, SBPs at FMC were higher than those at hospital admission for the SBP ≥ 180 mmHg subgroups of both type A (194 mmHg vs. 159 mmHg, p < 0.001) and type B (199 mmHg vs. 186 mmHg, p < 0.001). Approximately 10 min after symptom onset and before hospital transfer, the measured SBPs of many patients with type A AAD were not necessarily high. However, the SBPs of cases with type B AAD were high as previously reported for SBP on admission. In addition, for the subgroup of SBP ≥ 180 mmHg at FMC within 15 min after symptom onset, SBPs at FMC were significantly higher than those at hospital admission for both types A and B; the higher SBP at symptom onset may have been partially associated with being a trigger of AD.

BACKGROUND: The goals of this study were to evaluate mid-term outcome in endovascular aortic repair (EVAR) of abdominal aortic aneurysm (AAA) using a GORE C3 EXCLUDER and compare results between patients treated within and outside the instructions for use (IFU). METHODS: Over a 3-year period spanning October 2013 to September 2016, consecutive patients undergoing EVAR for AAA using the C3 EXCLUDER at Tokyo Medical University Hospital were registered on a prospectively maintained database. The data thus obtained were retrospectively analyzed. RESULTS: A total of 109 AAA patients underwent EVAR using the C3 EXCLUDER. The median follow-up duration was 729 days (interquartile range, 542-1,069 days). Technical success was achieved in 98.2% of cases. Adjunctive, unplanned proximal cuff-extender implantation was required in 8 patients (9.2%). Of the total number, 29 (24.8%) were categorized as being treated outside the IFU. No significant difference was observed in freedom from overall mortality or aneurysm-related mortality between patients treated within and outside the IFU. Freedom from reintervention tended to be lower in patients treated outside the IFU. There was aneurysm sac shrinkage (≥5 mm) in 30.3% and 39.1%; stable aneurysm sac in 69.7% and 56.3%; and aneurysm sac expansion (≥5 mm) in 0% and 4.7% of cases at 1 and 2 years, respectively. No significant difference was observed in aneurysm sac shrinkage between patients treated within and outside the IFU. CONCLUSIONS: The C3 EXCLUDER showed good clinical performance and aneurysm sac shrinkage, regardless of whether the patient was treated within or outside the IFU. The results suggest, however, that in those treated outside the IFU, precise planning, careful operative procedure, and subsequent follow-up are required to obtain short-term and mid- to long-term success in EVAR for AAA using the C3 EXCLUDER.

BACKGROUND: Pulmonary endarterectomy (PEA) is the treatment of choice for chronic thromboembolic pulmonary hypertension (CTEPH) but can result in respiratory and cardiac complications that may require extracorporeal membrane oxygenation (ECMO). We reviewed our experience with ECMO in patients undergoing PEA. METHODS AND RESULTS: Between January 2012 and August 2015, 35 patients underwent PEA for CTEPH. In all, four patients (11%) required veno-arterial (V-A) ECMO support due to severe cardiac and respiratory failure, including severe reperfusion pulmonary edema and persistent pulmonary hypertension. No significant differences in preoperative characteristics were found between patients who required ECMO and those who did not require ECMO. ECMO support was associated with a significantly higher incidence of postoperative respiratory complications, a longer intensive care unit stay, increased in-hospital mortality, residual pulmonary hypertension, and postoperative balloon pulmonary angioplasty (BPA). The postoperative mean pulmonary artery pressure and pulmonary vascular resistance were significantly higher in patients requiring ECMO. All patients requiring ECMO were successfully weaned off ECMO support (100%), and three of them were discharged from the hospital alive (75%). CONCLUSIONS: Patients with CTEPH may benefit from ECMO after PEA for cardiac and respiratory complications. A prompt decision to use V-A ECMO is critical for a successful outcome in these patients.

The preservation and repair of the aortic valve, since its valve annulus and leaflets have anatomically complicated 3-dimensional structures, is technically demanding with challenging aspects, and has not been a general surgical treatment, yet. However, in the recent trend of sparing and repair of the native valves in the cardiac surgical field, for aortic root diseases in relatively younger patients, valve sparing aortic root replacement has been attempted with the favorable outcome. In terms of its indication, such technically demanding surgeries had previously been indicated predominantly for patients without any valve deformities and significant aortic valve regurgitation, however in recent years, through the expanding indication with technical advances, they have been performed even for cases with some valve deformities including regurgitant bicuspid aortic valves. In this section, an up-to-data review would be described on valve sparing aortic root replacement, including its current indication, surgical techniques, and recent topics for discussion.

Abdominal aortic aneurysm (AAA) is a life-threatening disease, and no disease-specific circulating biomarkers for AAA screening are currently available. We have identified a smooth muscle cell (SMC)-specific biomarker for AAA. We cultured aneurysmal tunica media that were collected from eight patients undergoing elective open-repair surgeries. Secreted proteins in culture medium were subjected to liquid chromatography/tandem mass spectrometry. Myosin heavy chain 11 (myosin-11) was identified as a SMC-specific protein in the tunica media-derived secretions of all patients. We then examined myosin-11 protein concentrations by ELISA in plasma samples from patients with AAA ( n = 35) and age-matched healthy control subjects ( n = 34). Circulating myosin-11 levels were significantly higher in patients with AAA than control subjects. The area under the receiver-operating characteristic curve (AUC) of myosin-11 was 0.77, with a specificity of 65% at a sensitivity of 91%. Multivariate logistic regression analysis showed a significant association between the myosin-11 level and presence of AAA. When the myosin-11 level was combined with hypertension, it improved the prediction of AAA (AUC 0.88) more than hypertension per se. We then investigated the correlation between aortic diameter and circulating myosin-11 levels using AAA serum samples from patients undergoing endovascular aneurysm repair ( n = 20). Circulating myosin-11 levels were significantly correlated with maximum aortic diameter. Furthermore, changes in myosin-11 concentrations from the baseline 12 mo after endovascular aneurysm repair were associated with those in aortic diameter. These data suggest that circulating levels of myosin-11, which is a SMC-specific myosin isoform, may be useful as a biomarker for AAA. NEW & NOTEWORTHY Extensive studies have revealed that inflammation- or proteolysis-related proteins are proposed as biomarkers for abdominal aortic aneurysm (AAA). Changes in these protein concentrations are not specific for smooth muscle, which is a major part of AAA pathologies. Hence, no disease-specific circulating markers for AAA are currently available. We found, using secretome-based proteomic analysis on human AAA tunica media, that myosin heavy chain 11 was associated with AAA. Circulating myosin heavy chain 11 may be a new tissue-specific AAA marker.

Little is known regarding the consequences of bifurcation patency loss after failed crossover superficial femoral artery (SFA) stenting. We report on 2 cases concerning patients presenting with acute and chronic symptoms of critical limb ischemia after failed crossover SFA stenting and undergoing open surgical repair. We discuss the risk and management of failed crossover SFA stenting.

Sternal instability or dehiscence results in serious sternal wound infection. We sought to assess the early outcomes with such a plating system for sternal closure in comparison to the conventional wiring technique in off-pump coronary artery bypass grafting (CABG). Patients who underwent off-pump CABG were enrolled. Thirty-one patients received plate sternal fixation. A total of 64 patients who underwent off-pump CABG by a single surgeon at our hospital from July 2013 to December 2014 were enrolled. Thirty-one patients received plate sternal fixation (Plate group), while 33 received conventional wire closure (Wire group). The early outcomes, including the pain score and analgesic usage count were compared. Dietary intake was also recorded to assess the duration of appetite loss. At discharge, the largest sternal displacement was measured on computed tomography. In the Plate group, the pain scores were significantly lower on post-operative day 5-8 and POD 9-12 from those in the Wire group. The analgesic usage count on POD 9-12 was significantly lower in the Plate group. The duration of appetite loss and hospital stay was significantly shorter in the Plate group. The displacement in both the anterior-posterior and lateral directions was significantly smaller in the Plate group. Sternal closure by rigid plate fixation contributes to a more rapid post-operative recovery through reduced pain.
