Midterm survival after aortic repair versus conservative treatment in patients with penetrating aortic ulcer.

Background: The clinical outcomes and survival of patients with penetrating aortic ulcers (PAU) were evaluated in a tertiary care hospital, comparing those who underwent aortic repair to those treated conservatively. Patients and methods: A retrospective single-centre analysis included all patients that underwent a computed tomography angiography (CT-A) scan with the diagnosis of a PAU between January 2009 and May 2019. "PAU" was identified in 1,493 of 112,506 CT-A scan reports in 576 patients. Clinical and angiomorphological data were collected. The primary outcome was overall survival (OS), with secondary outcomes focusing on identifying risk factors for poor OS. Survival probabilities were analysed by the Kaplan-Meier method using the log-rank test. A Cox hazard model using survival as dependent variable with stepwise backward eliminations based on the likelihood ratios was employed. Results: 315 PAUs were identified in 278 patients. The prevalence in the cohort was 0.8%. The mean age of the patients was 74.4 years, and they were predominantly male (n = 208, 74.8%). The mean ulcer depth was 11.8 mm (range 2-50 mm). Out of the patients, 232 were asymptomatic (83.5%). Among 178 PAUs (56.5%), high-risk factors, such as ulcer depth >10 mm, aortic diameter >40 mm, and ulcer length >20 mm, were observed. Aortic repair was associated with a better mean OS compared to conservatively managed patients (72.6 versus 32.2 months, p = 0.001). The Cox hazard model showed that ulcer depth >1 mm was associated with poor OS (HR 0.67, p = 0.048), while aortic repair was related to a better OS (HR 4.365, p<0.013). Conclusions: Aortic repair is associated with better OS, but this finding should be interpreted with caution because of differences in age and comorbidities between the groups. Further evaluation is warranted through prospective studies with randomized groups. Further assessment for angiomorphological parameters is recommended to identify patients at increased risk for poor OS.

Etiology and treatment patterns of ruptured extracranial carotid artery aneurysm.

OBJECTIVE: Rupture of an extracranial carotid artery aneurysm (ECAA) is a very rare and life-threatening condition. To obtain a comprehensive view of previous and current management of ruptured ECAAs (rECAAs), we analyzed all cases reported since 1940 and two of our own cases. METHODS: We performed a comprehensive literature review of reports from the MEDLINE database on rECAAs and included two patients treated in our department. RESULTS: A total 58 reports of 74 rECAAs in 74 patients were analyzed. Their mean age was 50 years, and the male/female ratio was 2.2:1. Infection was the most common reported etiology (19 of 74; 26%), followed by connective tissue disorder (13 of 74; 18%), atherosclerosis (9 of 74; 12%), and previous trauma (5 of 74; 7%). For 28 patients (38%), information on the etiology was not available. Of the 74 patients, 24 (32%) had undergone reconstructive surgery, 10 (14%) had undergone endovascular treatment, 17 (23%) had undergone ligation, 2 (3%) had been treated conservatively, and 1 (1%) had died before receiving definite treatment. For 20 patients (27%), information on the treatment received was not available. The complications after reconstruction included carotid blowout (3 of 24 patients; 13%) and cranial nerve deficit (3 of 24 patients; 13%). Two patients (8%) had died of unrelated ECAA causes during long-term follow-up, and one patient (4%) had died of an ECAA-related cause within 30 days. After an endovascular approach, 1 of the 10 patients had developed a cranial nerve deficit. After ligation, five patients (29%) had experienced stroke, three of which were fatal. One conservatively treated patient had experienced no complications and one had died of an ECAA-related cause. CONCLUSIONS: The most common reported etiology for rECAA was infection. Reconstructive surgery was the most common approach and was safer than ligation, which carried a high risk of stroke. Endovascular treatment showed promising results, especially for distally located aneurysms; however, the number of patients has remained low.

Mortality in Patients with Brainstem Cavernous Malformations.

OBJECTIVE: Brainstem cavernous malformations (BSCM)-associated mortality has been reported up to 20% in patients managed conservatively, whereas postoperative mortality rates range from 0 to 1.9%. Our aim was to analyze the actual risk and causes of BSCM-associated mortality in patients managed conservatively and surgically based on our own patient cohort and a systematic literature review. METHODS: Observational, retrospective single-center study encompassing all patients with BSCM that presented to our institution between 2006 and 2018. In addition, a systematic review was performed on all studies encompassing patients with BSCM managed conservatively and surgically. RESULTS: Of 118 patients, 54 were treated conservatively (961.0 person years follow-up in total). No BSCM-associated mortality was observed in our conservatively as well as surgically managed patient cohort. Our systematic literature review and analysis revealed an overall BSCM-associated mortality rate of 2.3% (95% CI: 1.6-3.3) in 22 studies comprising 1,251 patients managed conservatively and of 1.3% (95% CI: 0.9-1.7) in 99 studies comprising 3,275 patients with BSCM treated surgically. CONCLUSION: The BSCM-associated mortality rate in patients managed conservatively is almost as low as in patients treated surgically and much lower than in frequently cited reports, most probably due to the good selection nowadays in regard to surgery.

Therapeutic management of acute type A aortic intramural hematoma.

OBJECTIVES: The proper therapeutic management for acute type A aortic intramural hematoma (IMH) is still controversial. The purpose of this study was to compare the outcomes following emergency surgery or conservative treatment for patients with this disease. METHODS: From January 2015 to December 2018, 124 consecutive patients were diagnosed with an acute type A aortic IMH and were included in this study. According to our surgical indications, they were divided into two groups: an operation group (OG) and a conservative treatment group (CG). RESULTS: Of 124 patients, 83 (66.9%) patients accepted emergency surgery and 41 (33.1%) patients accepted strict conservative treatment. There were no differences between these two groups in early mortality and complications. However, the late mortality of patients in the CG was significantly higher than for patients in the OG. A maximum aortic diameter in the ascending aorta and aortic arch ≥ 45 mm and maximum thickness of IMH in the same section ≥ 8 mm were risk factors for IMH related death in patients undergoing conservative treatment. CONCLUSIONS: The mortality associated with emergency surgery for patients with acute type A aortic IMH was satisfactory. In clinical centers with well-established surgical techniques and postoperative management, emergency surgical treatment may provide a better outcome than medical treatment for patients with acute type A aortic IMH.

Predictors of mortality and adverse events in patients with infective endocarditis: a retrospective real world study in a surgical centre.

PURPOSE: Mortality in infective endocarditis (IE) is still high, and the long term prognosis remains uncertain. This study aimed to identify predictors of long-term mortality for any cause, adverse event rate, relapse rate, valvular and ventricular dysfunction at follow-up, in a real-world surgical centre. METHODS: We retrospectively analyzed 363 consecutive episodes of IE (123 women, 34%) admitted to our department with a definite diagnosis of non-device-related IE. Median follow-up duration was 2.9 years. Primary endpoints were predictors of mortality, recurrent endocarditis, and major non-fatal adverse events (hospitalization for any cardiovascular cause, pace-maker implantation, new onset of atrial fibrillation, sternal dehiscence), and ventricular and valvular dysfunction at follow-up. RESULTS: Multivariate analysis independent predictors of mortality showed age (HR per unit 1.031, p < 0.003), drug abuse (HR 3.5, p < 0.002), EUROSCORE II (HR per unit 1.017, p < 0.0006) and double valve infection (HR 2.3, p < 0.001) to be independent predictors of mortality, while streptococcal infection remained associated with a better prognosis (HR 0.5, p < 0.04). Major non-fatal adverse events were associated with age (HR 1.4, p < 0.022). New episodes of infection were correlated with S aureus infection (HR 4.8, p < 0.001), right-sided endocarditis (HR 7.4, p < 0.001), spondylodiscitis (HR 6.8, p < 0.004) and intravenous drug abuse (HR 10.3, p < 0.001). After multivariate analysis, only drug abuse was an independent predictor of new episodes of endocarditis (HR 8.5, p < 0.001). Echocardiographic follow-up, available in 95 cases, showed a worsening of left ventricular systolic function (p < 0.007); severe valvular dysfunction at follow-up was reported only in 4 patients, all of them had mitral IE (p < 0.03). CONCLUSIONS: The present study highlights some clinical, readily available factors that can be useful to stratify the prognosis of patients with IE.

What Are the Functional Outcomes and Pain Scores after Medial Clavicle Fracture Treatment?

BACKGROUND: Medial clavicle fractures are uncommon, occurring in older and multiply injured patients. The management of these fractures and the factors that predispose toward poor outcomes are controversial. Furthermore, the functional outcomes of treatment are not well characterized or correlated with fracture patterns. QUESTIONS/PURPOSES: (1) To determine minimum 1-year functional outcomes using QuickDASH scores and pain scores after medial clavicle fractures and (2) to identify factors associated with these outcome variables. METHODS: In an institutional review board-approved, retrospective study, we identified adult patients with medial clavicle fractures at two tertiary care referral centers in a single metropolitan area in the United States from January 2010 to March 2019. Our initial query identified 1950 patients with clavicle fractures, from which 74 adult patients with medial clavicle fractures and at least 1 year of follow-up were identified. We attempted to contact these eligible patients by telephone for functional outcomes and pain scores. Twenty-six patients were deceased according to the most recent Social Security Death Index data and public obituaries, three declined participation, and 14 could not be reached, leaving 42% of the total (31 of 74) and 65% (31 of 48) of living patients included in the analysis. Demographic characteristics, fracture characteristics, and clinical and radiographic union as assessed by plain radiography and CT were collected through record review. Twenty-nine patients were treated nonoperatively and two patients underwent open reduction internal fixation. Sixty-eight percent (21 of 31) of the included patients also had radiographic follow-up at least 6 weeks postoperatively; two patients had persistent nonunion at a mean of 5 ± 3 years after injury. Our primary response variable was the QuickDASH score at a minimum of 1 year (median [range] 5 years [2 to 10]). Our secondary response variable was the pain score on a 10-point Likert scale. A bivariate analysis was performed to identify factors associated with these response variables. The following explanatory variables were studied: age, gender, race, dominant hand injury, employment status, manual labor occupation, primary health insurance, social deprivation, BMI, diabetes mellitus, smoking status, American Society of Anesthesiologists physical status classification, Charlson Comorbidity Index, nonisolated injury, high-energy mechanism of injury, nondisplaced fracture, fracture comminution, superior-inferior fracture displacement, medial-lateral fracture shortening, and surgical treatment of the medial clavicle fracture. RESULTS: The mean QuickDASH score was 12 ± 15, and the mean pain score was 1 ± 1 at a mean of 5 ± 3 years after injury. The mortality rate of the cohort was 15% (11 of 74) at 1 year, 22% (16 of 74) at 3 years, and 34% (25 of 74) at 5 years after injury. With the numbers available, no factors were associated with the QuickDASH score or pain score, but it is likely we were underpowered to detect potentially important differences. CONCLUSION: Medial clavicle fractures have favorable functional outcomes and pain relief at minimum 1-year follow-up among those patients who survive the trauma, but a high proportion will die within 3 years of the injury. This likely reflects both the frailty of a predominantly older patient population and the fact that these often are high-energy injuries. The outcome measures in our cohort were not associated with fracture displacement, shortening, or comminution; however, our sample size was underpowered on these points, and so these findings should be considered preliminary. Further studies are needed to determine the subset of patients with this injury who would benefit from surgical intervention. LEVEL OF EVIDENCE: Level IV, therapeutic study.

Short- and long-term outcomes in isolated penetrating aortic ulcer disease.

BACKGROUND: The optimum management of isolated penetrating aortic ulceration (PAU), with no associated intramural hematoma or aortic dissection is not clear. We evaluate the short- and long-term outcomes in isolated PAU to better inform management strategies. METHODS: We conducted a retrospective review of 43 consecutive patients (mean age, 72.2 years; 26 men) with isolated PAU (excluding intramural hematoma/aortic dissection) managed at a single tertiary vascular unit between November 2007 and April 2019. Twenty-one percent had PAU of the arch, 62% of the thoracic aorta, and 17% of the abdominal aorta. Conservative and surgical groups were analyzed separately. Primary outcomes included mortality, PAU progression, and interventional complications. RESULTS: Initially, 67% of patients (29/43) were managed conservatively; they had significantly smaller PAU neck widths (P = .04), PAU depths (P = .004), and lower rates of associated aneurysmal change (P = .004) compared with those initially requiring surgery. Four patients (4/29) initially managed conservatively eventually required surgical management at a mean time interval of 49.75 months (range, 9.03-104.33 months) primarily owing to aneurysmal degeneration. Initially, 33% of patients (14/43) underwent surgical management; 7 of the 14 procedures were urgent. Of the 18 patients, 17 eventually managed with surgical intervention had an endovascular repair; 2 of the 17 endovascular cases involved supra-aortic debranching, six used scalloped, fenestrated, or chimney stents. The overall long-term mortality was 30% (mean follow-up, 48 months; range, 0-136 months) with no significant difference between the conservatively and surgically managed groups (P = .98). No aortic-related deaths were documented during follow-up in those managed conservatively. There was no in-hospital mortality after surgical repair. Of these 18 patients, two required reintervention within 30 days for type I or III endoleaks. Among the 18 patients, seven died during follow-up (mean survival, 90.24 months; range, 66.48-113.88) with 1 of the 18 having a confirmed aortic-related death. CONCLUSIONS: Isolated, asymptomatic, small PAUs may be safely managed conservatively with regular surveillance. Those with high-risk features or aneurysmal progression require complex strategies for successful treatment with acceptable long-term survival.

Evaluation of a risk index for predicting short-term and long-term outcomes in patients with ST-elevation myocardial infarction.

OBJECTIVE: This study aimed to evaluate the usefulness of the admission risk index (RI) to predict short-term and long-term outcomes in a broad population with ST-elevation myocardial infarction (STEMI) using data from the Chinese Acute Myocardial Infarction Registry. BACKGROUND: The RI was developed as a simple tool to predict risk of death in STEMI patients. The performance in predicting short-term and long-term risk of death in Chinese patients receiving percutaneous coronary intervention and conservative treatment for STEMI remains unclear. METHODS: Age, heart rate (HR), and systolic blood pressure (SBP) were used to calculate RI using (HR×[age/10]2 )/SBP. We used the prediction tool to predict mortality over 12 months. RESULTS: The C-index of the admission RI for predicting in-hospital, 1-, 6-, and 12-months mortality were 0.78, 0.78, 0.78, and 0.77, respectively, compared with 0.75 of the Global Registry in Acute Coronary Events score. Based on the receiver operating characteristic curve analysis, the RI was categorized into quintiles for convenient clinical use, and it revealed a nearly 15-fold gradient of increasing mortality from 2.29 to 32.5% (p < .0001) while RI >34 had the highest mortality. By categorizing into five different risk groups, the short-term and long-term mortality of patients receiving different treatments could be distinguished. CONCLUSIONS: RI based on three routine variables and easily calculated by any medical practitioner is useful for predicting in-hospital and long-term mortality in patients with STEMI at the initial consultation with clinicians.

Spontaneous Rectus Sheath Hematoma: Factors Predictive of Conservative Management Failure.

PURPOSE: To evaluate radiographic, laboratory, and clinical factors associated with conservative management (CM) failure in spontaneous rectus sheath hematoma (RSH). MATERIALS AND METHODS: Retrospective review of 72 patients with spontaneous RSH between 2006 and 2017 was performed. Patients were initially managed conservatively and then divided into 2 groups based on decision to embolize. No differences were found between embolization (n = 32) and CM (n = 40) groups in age (67.5 vs 69.5 y; P = .79), sex (31% vs 38% male; P = .58), body mass index (27.7 vs 25.7 kg/m2; P = .20), or medical comorbidities. Univariate analyses compared initial hemoglobin level, change in hemoglobin level, coagulation parameters, transfusion requirements, hematoma volume, and active extravasation on computed tomographic (CT) angiography between groups. Multivariable logistic regression identified factors predictive of CM failure. A scoring system was then created to predict CM failure. RESULTS: CM failed in 32 of 72 patients. Multivariable regression identified active extravasation on CT angiography (P = .02), hematoma volume (P = .01), and packed red blood cell (pRBC) transfusion of ≥ 4 U (P = .03) as predictors of embolization. A scoring system using these factors along with maximum rate of hemoglobin decrease yielded a sensitivity of 100% and specificity of 98% in determining need for embolization. CONCLUSIONS: CM for RSH was more likely to fail in patients with active extravasation on CT angiography, larger hematoma volume, pRBC transfusion of ≥ 4 U, and higher rate of hemoglobin decrease. Using these parameters, a scoring system was created that achieved high sensitivity and specificity in identifying patients who would require embolization.

Age-Related Differences in the Effects of Initial Aortic Valve Replacement vs. Conservative Strategy on Long-Term Outcomes in Asymptomatic Patients With Severe Aortic Stenosis.

BACKGROUND: This study aimed to evaluate the effect of the initial aortic valve replacement (AVR) strategy relative to a conservative strategy on long-term outcomes stratified by age among asymptomatic patients with severe aortic stenosis (AS).Methods and Results:Among 1,808 asymptomatic severe AS patients in the CURRENT AS registry, there were 1,166 patients aged ≥75 years (initial AVR: n=124, and conservative: n=1,042), and 642 patients with age <75 years (initial AVR: n=167, and conservative: n=475). Median follow-up interval was 1,280 (interquartile range [IQR]: 1,012-1,611) days, and 1461 (IQR: 1,132-1,886) days in patients aged ≥ and <75 years, respectively. The favorable effect of the initial AVR strategy relative to conservative strategy for heart failure (HF) hospitalization was seen regardless of the age stratum (≥75 years: adjusted hazard ratio [HR] 0.13, 95% confidence interval [CI] 0.05-0.34, and <75 years: HR 0.37, 95% CI 0.14-0.99, interaction P=0.35). However, the lower mortality risk of the initial AVR strategy relative to conservative strategy was significant in patients aged ≥75 years, but not in patients <75 years, with significant interaction (HR 0.35, 95% CI 0.20-0.61, and HR 0.69, 95% CI 0.41-1.16, interaction P=0.016). CONCLUSIONS: The benefit of initial AVR in reducing HF hospitalization in asymptomatic patients with severe AS was consistently seen regardless of age. The magnitude of mortality benefit of initial AVR was greater in super-elder patients than in non-super-elder patients.

Carotid endarterectomy versus conservative management of the asymptomatic carotid stenosis before coronary artery bypass grafting: a retrospective study.

BACKGROUND: Our retrospective single-center study aimed to evaluate the safety of the carotid endarterectomy (CEA) in comparison to patients with untreated asymptomatic carotid stenosis ≥60% before CABG. METHODS: This single-center retrospective study included 174 patients with asymptomatic unilateral carotid stenosis treated between 2004 and 2017 with CABG. Thereof 106 patients had CEA before cardiac surgery either by a simultaneous (n = 62) or staged (n = 44) approach. Patients with untreated carotid stenosis served as control (no-CEA group; n = 68). RESULTS: The mean stenosis grade was higher in the CEA group (CEA 83% (±1), no-CEA 71% (±1) p < 0.0001). The overall stroke rate was 5/174 (3%) and was due to a high incidence of stroke in the no-CEA group (CEA: 0/106 (0%); No-CEA 5/68 (7%) p = 0.0083). The overall mortality was 1% and comparable between the groups (CEA: 2/106 (2%); No-CEA 0/68 (0%) p = 0.5211). Stroke related mortality was not observed. The groups were similar regarding the incidence of myocardial infarction (p = 1.0), atrial fibrillation (p = 0.1931), delirium (p = 0.2106) and IMC/ICU stay (p = 0.1542). No significant difference in the subgroup analysis was found between the simultaneous and staged approach regarding the myocardial infarction (simultaneous: 1/62 (1%); staged: 1/44 (1%); p = 1.0). CONCLUSIONS: CEA performed as a staged procedure in local anesthesia or a simultaneous procedure in general anesthesia, may reduce the stroke risk prior to CABG.

Percutaneous coronary intervention in the very elderly with NSTE-ACS: the randomized 80+ study.

Objective: The treatment strategy in the very elderly with NSTE-ACS is debated, as they are often under-represented in clinical trials. The aim of this multicenter randomized controlled trial was to compare invasive and conservative strategies in the very elderly with NSTE-ACS.Methods: We randomly assigned patients ≥ 80 years of age with NSTE-ACS to an invasive strategy with coronary angiography and optimal medical treatment or a conservative strategy with only optimal medical treatment. The primary outcome was the combined endpoint of major adverse cardiac and cerebrovascular events (MACCE). Sample size was powered for a 50% reduction of event rate in MACCE with an invasive strategy. We used intention-to-treat analysis.Results: Altogether, 186 patients were included between 2009 and 2017. The study was terminated prematurely due to slow enrollment. At 12-month follow-up, the primary outcome occurred in 31 (33.3%) of the invasive treatment group and 34 (36.6%) of the conservative treatment group, with a hazard ratio (HR) of 0.90 (95% CI 0.55‒1.46; p = 0.66) for the invasive group relative to the conservative group. The corresponding HR value for urgent revascularization was 0.29 (95% CI 0.10‒0.85; p = 0.02), 0.56 (95% CI 0.27‒1.18; p = 0.13) for myocardial infarction, 0.70 (95% CI 0.31‒1.58; p = 0.40) for all-cause mortality, 1.35 (95% CI 0.23‒7.98; p = 0.74) for stroke, and 1.62 (95% CI 0.67‒3.90; p = 0.28) for recurrent hospitalization for cardiac reasons.Conclusion: In the very elderly with NSTE-ACS, we did not find any significant difference in MACCE between invasive and conservative treatment groups at 12-month follow-up, possibly due to small sample size. ClinicalTrials.gov: NCT02126202.

A novel risk score on admission for predicting death or need for surgery in patients with acute type A intramural hematoma receiving medical therapy.

There has been continuing discussion regarding the treatment strategy for acute type A intramural hematoma (IMH). Most patients are treated conservatively in Japan; hence, predicting fatal events and stratifying risks based on results normally obtained on hospital arrival are important. We aimed to examine the incidences and risk factors of death or need for surgery for acute type A IMH in patients receiving medical treatment and to identify high-risk patients using clinical findings on hospital arrival. From 2011 to 2016, 57 consecutive patients (mean age 72.5 years; male 36.8%) diagnosed with acute type A IMH who were receiving treatment at Shizuoka City Shizuoka Hospital were retrospectively included. Primary endpoint was a composite of cardiovascular death and operation within 1 year after onset. To evaluate sensitivity and specificity of the risk factors and risk score, we estimated the area under the receiver operating characteristic (ROC) curve. Mean follow-up duration was 621 days. Mean systolic blood pressure (SBP) was 129 mmHg. Computed tomography (CT) on arrival showed a mean ascending aorta diameter of 46 mm. Ulcer-like projection (ULP) in the ascending aorta and pericardial effusion (PE) were seen in 33% and 42% of cases, respectively. Twenty-eight patients (49.1%) reached the primary endpoint (cardiovascular death, 7 cases [12.3%]; operation, 21 cases [36.8%]). In univariate analysis of admission values, the primary endpoint group had significantly lower SBP (113.0 ± 28.5 vs 144.3 ± 33.5 mmHg), higher ascending aorta diameter (49.5 ± 8.1 vs 43.6 ± 5.9 mm), and higher frequency of ULP (53.8% vs 13.8%) and PE (58.6% vs 25.0%) than the event-free group. Multivariate analysis showed that ULP on admission CT was a significant predictor of the primary endpoint. The risk score was considered using these risk factors. On admission, the primary endpoint could be predicted with 89.7% sensitivity and 75% specificity (area under the ROC curve 0.823) if the patient had ULP and/or > 2 of the following factors: SBP < 120 mmHg, ascending aorta diameter > 45 mm, and PE. SBP and CT findings on arrival were significantly associated with cardiovascular death and the need for surgery in patients with acute type A IMH receiving initial medical therapy. The novel risk score was useful for predicting cardiovascular death and surgery.

Clinical profiles and outcomes in the treatment of acute myocardial infarction in Japan of aging society.

To address many uncertainties in the acute care of patients with acute myocardial infarction (AMI) in proportion to increasing age, we underwent the nationwide current survey consisted of 11,676 patients with AMI based on the database of the Japanese Acute Myocardial Infarction Registry between January 2011 and December 2013 to figure out how difference of clinical profiles and outcomes between coronary revascularization and conservative treatments for AMI. Clinical profiles in a total of 763 patients with AMI with conservative treatments (7% of all) were characterized as more elderly women (median age, 71 yeas vs. 68 years, p < 0.0001, male, 71% vs. 76%, p = 0.0008), high Killip class (Killip class I, 61% vs. 75%, p < 0.0001), and non-ST-segment elevation AMI (37% vs. 27%, p < 0.0001) as compared with 10,913 with coronary revascularization, with a consequence of more than twofold higher in-hospital mortality (12% vs. 5%, p < 0.0001). When compared with conservative treatments, highly effective of coronary revascularization to decrease in-hospital mortality was found in patients with ST-segment elevation AMI (6% vs. 16%, p < 0.0001), while these advantages were not evident in those with non-ST-segment elevation AMI (4% vs. 6%, p = 0.1107), especially with high Killip class, regardless of whether or not propensity score matching of clinical characteristics. A risk-adapted allocation of invasive management therefore may have the potential of benefiting patients with non-ST-segment elevation AMI, in particular elders.

Surgical Experience of Behcet's Disease Involving the Peripheral Artery.

BACKGROUND: Behcet's disease with arterial involvement shows rapid poor progression compared with Behcet's disease without arterial involvement, such that it may be thought of as a different disease. With arterial involvement, high rates of postoperative recurrence and anastomotic complications are observed. METHODS: The medical records of 1,361 patients diagnosed with Behcet's disease who visited our hospital from January 2007 to December 2019 were reviewed. Overall, 118 patients with blood vessel involvement were considered. Those with only vein involvement, intracerebral arterial involvement, and coronary arterial involvement were excluded. The 8 patients who underwent surgical treatments and the 9 patients who underwent conservative treatments were included and reported in this study. RESULTS: The mean age and mean follow-up duration of the 17 patients with peripheral arterial involvement were 49.82 ± 13.24 years and 89.85 ± 52.70 months, respectively. In all cases where the operations were performed, the first operation was an emergency operation for rupture of the aneurysm, impending sign of rupturing, or acute ischemia. Eight patients received a total of 18 operations. The average number of operations per patient and the reoperation rate were 2.25 ± 0.89 times and 75%, respectively. The 5-year and 10-year survival rates of the patients who underwent surgery were 75.0% and 30.0%, respectively. When arterial involvement occurs in the form of an aneurysm, the hazard ratio for death is 9.644 (P = 0.040, confidence interval 1.11-83.74). CONCLUSIONS: When the artery invades in the form of an aneurysm, the mortality rate is higher regardless of surgery. The main cause of mortality is complications that occur in the anastomosis sites after the operation. Postoperative short-term and regular imaging of the anastomosis area can be beneficial to detect such complications early to decrease the frequency of emergency surgeries, which will help reduce mortality.

Variations in the Management of Claudication in a Tertiary Care Center.

BACKGROUND: Multiple societal guidelines recommend medical optimization and exercise therapy for patients with claudication prior to lower extremity revascularization (LER). However, the application of those guidelines in practice remains unknown. Our hypothesis is that vascular surgeons (VS) are more adherent to guidelines compared to non-VS treating claudication. METHODS: The records of patients undergoing LER for claudication in a single center were reviewed, and adherence to guidelines prior to LER was assessed. Patients received conservative therapy if the impact of claudication on quality of life was documented, ankle-brachial index (ABI) was obtained, and patients were treated with at least 3 months of walking exercise and smoking cessation when indicated. RESULTS: There were 187 patients treated for claudication (VS = 65, non-VS = 122). There were 161 patients who underwent endovascular intervention, 19 patients had an open revascularization, and 7 patients had a hybrid procedure. Patients treated by VS were younger and more likely to be African American. Patients treated by non-VS were more likely to have hyperlipidemia, coronary artery disease, smoke, and be on antiplatelet and statin medications. VS was more likely to assess pattern of symptoms with claudication and obtain ABIs compared to non-VS, although the mean ABIs were no different. VS was more likely to use walking exercises and smoking cessation when indicated before LER. Even though 70.8% and 31.1% of patients treated by VS and non-VS respectively were recommended walking exercises, only 33.8% and 18.0% were given a period of 3 months to benefit from it prior to LER. Conservative therapy was significantly higher among VS compared to non-VS but was overall low (VS = 12.3%, non-VS = 3.3%, P = 0.016). After a mean follow-up of 3.1 ± 1.3 years, there was no difference in mortality or major amputation. CONCLUSIONS: Although adherence to guidelines in the medical management of vascular claudication prior to LER was higher among VS compared with non-VS, overall rates of adherence were low. Stricter institutional protocols and oversight across specialties are needed to reinforce the application of the established standards of care.

Role of Frailty and Comorbidity Status in Predicting Morbidity and Mortality in Patients with Acute Mesenteric Ischemia.

BACKGROUND: This study was performed to determine the association of frailty and comorbidity status with postoperative morbidity and mortality in patients with acute mesenteric ischemia (AMI). METHODS: Patients diagnosed with AMI between April 2006 and September 2019 were enrolled in this study. Frailty was evaluated by sarcopenia which was diagnosed by third lumbar vertebra psoas muscle area (PMA). Comorbidity status was evaluated by the Charlson Comorbidity Index (CCI) score. Univariate and multivariate analyses evaluating the risk factors for postoperative morbidity and mortality were performed. RESULTS: Of the 174 patients, 86 were managed conservatively and 88 underwent surgery. In surgically managed patients, 39.8% developed complications within 30 days of surgery. Ten patients died within 30 days of the operation. In the univariate analyses, white blood cell >10 g/L, low PMA, CCI score ≥2, and bowel resection were associated with postoperative complications. Multivariate analysis revealed that low PMA, CCI score ≥2, and bowel resection were independent predictors of postoperative complications. CONCLUSIONS: This study demonstrated that low PMA, CCI score ≥2, and bowel resection were independent risk factors for postoperative complications in patients with AMI. Preoperative assessment of frailty using PMA and the evaluation of comorbidity status using CCI may serve as helpful tools in preoperative risk assessment and should be integrated into scoring systems for surgically treated AMI.

Treatment of Lymphatic Complications after Common Femoral Artery Endarterectomy.

BACKGROUND: This study analyzes the outcome of lymphatic complications after a standard vascular procedure. METHODS: This is a retrospective study including patients who had a lymphatic complication after endarterectomy and patch of the common femoral artery in our clinic between March 2007 and June 2018. Therapy of choice was selected according to wound situation and amount of lymphatic liquid. If signs of a wound infection occurred, a surgical therapy was performed; in all other cases a nonsurgical treatment (conservative treatment, radiotherapy) was chosen. RESULTS: We performed 977 index operations, a lymphatic complication occurred in 112 cases (11.5%). In 69 cases the lymphatic complication presented as lymphatic fistula (Group 1), in 43 cases as lymphorrhea from the wound (Group 2). Nonsurgical treatment was done in 66 cases (Group 1: 76.8% vs. Group 2: 30.2%; P < 0.000), and a surgical treatment was necessary in 46 cases (Group 1: 23.2% vs. Group 2: 69.8%; P < 0.000). Indication for surgery was Szilagyi 1 infection in 25 cases, Szilagyi 2 infection in 11 cases, and Szilagyi 3 infection in 10 cases. Patients with Szilagyi 1 infections received negative wound pressure therapy (NWPT). A muscle flap in combination with an NWPT was performed in patients with Szilagyi 2 infections. In Szilagyi 3 infections, the patch was replaced; additionally, a muscle flap and an NWPT were performed. The median hospital stay was 13 days in the nonsurgical group and 22.5 days in the surgical group. We had no bleeding complications and no reinfection during follow-up. The median observation period was 23.0 months. Age ≥80 years was associated with an increased risk for lymphatic complications. CONCLUSIONS: The therapy of lymphatic complications should be done in accordance with clinical symptoms. A nonsurgical treatment is often sufficient. However, in cases of a wound infection different surgical treatments are necessary.

Survival and mortality of elderly men with localized prostate cancer managed with primary androgen deprivation therapy or by primary observation.

BACKGROUND: Androgen deprivation therapy (ADT) remains a primary treatment for localized prostate cancer (PCa) even though there is no evidence that its use is beneficial in the absence of curative treatment. METHODS: Men aged ≥70 years (n = 16,534) diagnosed with localized PCa from 1985 to 2014 and managed either with primary observation or ADT in the absence of curative treatment were included. The cases were identified from the population-based Finnish Cancer Registry. We estimated the standardized mortality ratios (SMR) for overall mortality by treatment group. We determined the relative risk (RR) of PCa-specific mortality (PCSM) and other-cause mortality between the two treatment groups. Survival was determined using the life table method. Two age groups (70-79 years and ≥ 80 years) and three calendar time cohorts (1985-1994, 1995-2004, and 2005-2014) were compared following adjustment of propensity score matching between the treatment groups with four covariates (age, year of diagnosis, educational level, and hospital district). Follow-up continued until death or until December 31, 2015. RESULTS: Patients in the observation group had lower overall SMRs than those in the ADT group in both age cohorts over the entire study period. PCSM was higher in men aged 70-79 years undergoing primary ADT compared to those managed by observation only (RR: 1.70, 95% confidence interval [CI]: 1.29-2.23 [1985-1994]; RR 1.55, 95% CI: 1.35-1.84 [1995-2004]; and RR 2.71, 95% CI: 2.08-3.53 [2005-2014]); p = 0.005 for periodic trend. A similar trend over time was also observed in men aged > 80 years; (p for age-period interaction = 0.237). Overall survival was also higher among men in their 70's managed by observation compared to those undergoing ADT. CONCLUSIONS: Primary ADT within four months period from diagnosis is not associated with improved long-term overall survival or decreased PCSM compared to primary conservative management for men with localized PCa. However, this observational study's conclusions should be weighted with confounding factors related to cancer aggressiveness and comorbidities.

High mortality following distal femur fractures: a cohort study including three hundred and two distal femur fractures.

PURPOSE: What are the overall, 30-day, 6-month, and 1-year mortality rates following distal femur fractures? METHODS: Epidemiological cohort study. Retrospective reviews of charts and X-rays based on a search in the National Danish Health Registry. RESULTS: A total of 293 patients were treated for 302 distal femur fractures between 2005 and 2010. The mean age at the time of fracture was 44.0 years for males and 71.6 years for females. The overall mortality rates after a non-periprosthetic distal femur fracture at 30 days, six months, and one year were 5%, 15%, and 21%, respectively. The mortality rates for patients at > 60 years at 30 days, six months, and one year were 8%, 26%, and 35%, respectively. The mortality rates for patients at ≤ 60 years at 30 days, six months, and one year were 1%, 2%, and 3%, respectively. The overall mortality rates after a periprosthetic distal femur fracture at 30 days, six months, and one year were 10%, 15%, and 15%. Males were 2.6 (95% CI 1.01-6.86, P = 0.04) times more likely to die within the first year compared to women. Patients treated by conservative means shows a 2.8 (95% CI 1.41-5.54, P = 0.03) times increased likelihood of death within the first year compared to patients treated with surgery. CONCLUSIONS: The overall one year mortality rate was 21% for non-periprosthetic distal femur fractures and was elevated to 35% in patients older than 60 years. Patients presenting with a periprosthetic fracture showed a one year mortality rate of 15%.
