Comparison of percutaneous access and open femoral cutdown in elective endovascular aortic repair of abdominal aortic aneurysms.

Background: The aim of this study was to compare postoperative outcomes of percutaneous access and femoral cutdown methods for elective bifurcated endovascular abdominal aortic aneurysm repair. Methods: Between November 2013 and September 2020, a total of 152 patient (135 males, 17 females; mean age: 70.6±6, range, 57 to 87 years) who underwent endovascular repair due to infrarenal abdominal aortic aneurysm were retrospectively analyzed. According to femoral access type, the patients were grouped into two groups as the total percutaneous femoral access and open cutdown femoral access endovascular repair. Intra- and postoperative data were compared, including operative time, amount of contrast media, bleeding requiring transfusion, return to the operating room, access vessel complications, wound complications, and overall length of hospital stay. Results: Eighty-seven (57.2%) femoral cutdown access repair and 65 (42.8%) percutaneous femoral access repair cases were evaluated in the study. The two groups were comparable in terms of demographic and clinical characteristics (p>0.05), except for chronic obstructive pulmonary disease which was more frequent in the percutaneous access group (p=0.014). After adjustment, age, diabetes mellitus, chronic obstructive pulmonary disease, and obesity were not predictive of percutaneous access failure. Percutaneous femoral access was observed as the only preventing factor for wound infection (odds ratio=0.166, 95% confidence interval: 0.036-0.756; p=0.021). Conclusion: Although femoral access preference does not affect mortality and re-intervention rates, percutaneous endovascular repair reduces operation time, hospital stay, and wound site complications compared to femoral artery exposures.

Comparison between arch zones in modified frozen elephant trunk procedure for complex thoracic aortic diseases

Abstract Introduction: The aim of this study is to compare postoperative outcomes and follow-up of two different modifications facilitating surgical technique of frozen elephant trunk (FET) procedure for complex thoracic aortic diseases - zone 0 (fixation with total arch debranching) and zone 3 (fixation with islet-shape arch repair). Methods: From May 2012 to December 2018, data were collected from 139 patients who had been treated with FET procedure for complex thoracic aortic diseases. According to Ishimaru arch map, patients with proximal anastomotic site of hybrid graft at zone 0 and zone 3 were grouped as Group A (n=58, 41.7%) and Group B (n=81, 58.3%), respectively. Mean age of study population was 54.7±11.4 years, and 111 patients were male (79.9%). Results: In-hospital mortality was observed in 20 (14.4%) patients (n=12, acute type A aortic dissection, and n=4, previous aortic dissection surgery). There was no significant difference between both groups in terms of in-hospital mortality. Four patients from Group A and three patients from Group B had permanent neurological deficit (P=0.32). Three patients from both groups had transient spinal cord ischemia (P=0.334). Although mean total perfusion time was longer in Group A, duration of visceral ischemia, when compared with Group B, was shorter (P<0.001). Five-year survival rate was 82.8% in Group A and 81.5% in Group B (P=0.876). Conclusion: FET procedure is a feasible repair technique in the treatment of complex aortic diseases, providing satisfactory early results. Because of its advantageous aspects, zone 0 fixation with debranching is the preferred technique in our clinic.

Compression of the Left Atrium and Pulmonary Veins Due to Ascending and Descending Aortic Aneurysms.

An 89-year-old female patient presented to our cardiology outpatient clinic complaining of shortness of breath and back pain. Chest X-ray demonstrated a widened mediastinum. Transthoracic echocardiography showed an ascending aortic aneurysm and the modified apical 5-chamber view showed that left atrium was compressed between the ascending and descending aortas. Color Doppler turbulence was also seen in the compressed area. A contrast-enhanced chest computed tomography scan in axial and coronal planes showed that left atrium and pulmonary veins were compressed by ascending and descending aortic aneurysms. Herein, we illustrated this rare condition diagnosed by transthoracic echocardiography in combination with computed tomography.

Hybrid Treatment of Complex Aortic Arch Anomaly with Saccular Aneurysm.

Aortic arch anomalies are not clinically important unless they cause compression symptoms due to aneurysmatic dilatation. Aortic anomalies need to be treated when they cause complex thoracic aortic diseases, and the treatment approach has evolved over time from open surgical methods, which have high mortality and morbidity rates, to hybrid methods. A case of a 68-year-old male patient with complex aortic arch anomaly treated with hybrid arch repair is reported in this study. Aortic branches were common carotid trunk and aberrant right subclavian artery with a saccular aneurysm.

Early and mid-term results of frozen elephant trunk procedure for acute type A aortic dissection.

BACKGROUND: This study aims to investigate the early and mid-term results of total thoracic aorta repair with E-vita OPEN PLUS stent graft, which we used to remove the residual false lumen and prevent late-term complications in patients with acute type A aortic dissections. METHODS: The study included 41 patients (29 males, 12 females; mean age 51.9±10.4 years; range, 30 to 77 years) who underwent total thoracic aorta repair with frozen elephant trunk stent graft for acute type A aortic dissection between November 2013 and November 2017. The reduction in false lumen size and thrombosis were evaluated by repeated computed tomographyangiography on 10th day and third, sixth, and 12th months. RESULTS: Six patients (14.6%) were lost during hospital stay and one patient (2.4%) was lost during the follow-up period. Frozen elephant trunk stent graft"s distal end at descending aorta ended at T6, T7, and T8 levels in 15 (36.6%), 21 (51.2%), and five (12.2%) patients, respectively. The supra-aortic vessels were re-implanted separately in 21 (51.2%) or as island in 20 (48.8%) patients. Transient paraparesis (spinal cord ischemia) was observed in only one patient (2.4%), while permanent neurologic deficit (stroke or coma) was observed in two patients (4.9%). Mean duration of follow-up was 26.5±20.5 months. Computed tomography-angiography at first month showed that false lumen became thrombosed at rates of 93.9% and 54.5% at pulmonary trunk and diaphragmatic level, respectively. CONCLUSION: We believe that total arcus repair in acute type A aortic dissection treatment with single-session frozen elephant trunk technique by ensuring early false lumen thrombosis is safe and successful.

Short-term results of flanged Bentall de Bono and valve-sparing David V procedures for the treatment of aortic root aneurysms.

AIM: Even though the Bentall de Bono procedure is widely used for the treatment of aortic root aneurysms, the procedure is under scrutiny nowadays because of complications due to mechanical prosthetic valves and the need for life-long anticoagulation. Due to these complications, aortic valve-sparing operations are being researched. In this study we compared the short-term morbidity and mortality rates of both Bentall de Bono and valve-sparing David V procedures. METHODS: We retrospectively evaluated data from 70 patients who had undergone surgery for aortic root aneurysm between April 2009 and June 2013. We had performed the Bentall de Bono procedure on 46 patients and the David V procedure on 24 patients. Mortality rates, cardpulmonary bypass (CPB) and aortic cross-clamp durations, postoperative arrhythmias, and prolonged intensive care unit (ICU) and hospital stays were compared in this study. RESULTS: There was no statistical difference for mortality rate (p = 0.57), while the CPB time and cross-clamp duration were shorter in the Bentall group. When we compared the length of ICU and hospital stay, we observed that the David group stayed longer in ICU (p = 0.003) but the duration of hospital stay was shorter (p = 0.007). CONCLUSION: Despite Bentall de Bono being the most commonly used procedure, the short-, mid- and long-term results of both procedures were similar. Spared native aortic valve and lack of anticoagulation usage are notable advantages of the David V procedure.

Outcomes After Surgical Resection of Primary Non-Myxoma Cardiac Tumors.

OBJECTIVE: Primary cardiac tumors are rare lesions with different histological type. We reviewed our 17 years of experience in the surgical treatment and clinical results of primary non-myxoma cardiac tumors. METHODS: Between July 2000 and February 2017, 21 patients with primary cardiac tumor were surgically treated in our institution. The tumors were categorized as benign non-myxomas and malignants. Data including the demographic characteristics, details of the tumor histology and grading, cardiac medical and surgical history, surgical procedure of the patients were obtained from the hospital database. RESULTS: Eleven patients were diagnosed with benign non-myxoma tumor (male/female:7/4), ranging in age from 10 days to 74 years (mean age 30.9±26.5 years). Papillary fibroelastoma was the most frequent type (63.6%). There were two early deaths in benign group (all were rhabdomyoma), and mortality rate was 18%. The mean follow-up period was 69.3±58.7 months (range, 3 to 178 months). All survivals in benign group were free of tumor-related symptoms and tumor relapses. Ten patients were diagnosed with malignant tumor (sarcoma/lymphoma:8/2, male/female:3/7), ranging in age from 14 years to 73 years (mean age 44.7±18.9 years). Total resection could be done in only three (30%) patients. The mean follow-up period was 18.7±24.8 months (range, 0-78 months). Six patients died in the first 10 months. CONCLUSION: Complete resection of the cardiac tumors, whenever possible, is the main goal of surgery. Surgical resection of benign cardiac tumors is safe, usually curative and provides excellent long-term prognosis. On the contrary, malignant cardiac tumors still remain highly lethal.

Neutrophil to lymphocyte ratio: a novel marker for predicting hospital mortality of patients with acute type A aortic dissection.

INTRODUCTION: The inflammatory process has been reported to be associated with aortic dissection (AD) from the development to the prognosis. The aim of the study was to investigate a relationship between the neutrophil to lymphocyte ratio (NLR) and in-hospital outcomes in patients with acute aortic dissection (AAD) who underwent surgical repair. METHODS: One hundred and eighty-four patients who were admitted with the diagnosis of type A AAD who underwent surgical repair at two large tertiary hospitals. According to their NLR, 91 patients had high NLR (>6.0) and 93 patients had low NLR (⩽6.0). RESULTS: The frequency of major bleeding, hospital-related infection, multi-organ dysfunction and mortality in hospital were higher in the high NLR group compared to the low NLR group. NLR, WBC count and operation duration were found to be independent predictors for in-hospital mortality. CONCLUSIONS: The novel inflammatory marker NLR may be used to predict worse outcomes and hospital mortality in patients with AAD treated by surgical repair.

The Predictive Value of Admission Fragmented QRS Complex for In-Hospital Cardiovascular Mortality of Patients with Type 1 Acute Aortic Dissection.

BACKGROUND: Fragmented QRS (fQRS) arises from impaired ventricular depolarization due to heterogeneous electrical activation of ischemic and/or infarcted ventricular myocardium. The short- and long-term prognostic values of fQRS have been reported for myocardial infarction, heart failure, fatal cardiac arrhythmias, and sudden cardiac death. The aim of this study was to investigate the predictive value of admission fQRS complex for in-hospital cardiovascular mortality of patients with type 1 acute aortic dissection (AAD). METHODS: In this retrospective study, 203 consecutive patients with type 1 AAD who had been admitted to either of two large-volume tertiary hospitals between December 2008 and October 2013 were included. The patients were divided into two groups according to the presence or absence of the fQRS complex on admission. RESULTS: In-hospital cardiovascular mortality (P < 0.001), major adverse cardiovascular events (P < 0.001), acute renal failure (P = 0.022), multiorgan dysfunction (P < 0.001), and acute decompensated heart failure (P < 0.001) were observed to be significantly more frequent in the fQRS-positive group than in the fQRS-negative group. fQRS (odds ratio [95% confidence interval]: 4.184 [1.927-9.082], P < 0.001), operation duration (4.184 [1.927-9.082], P = 0.001), and Killip class IV (3.900 [1.699-8.955], P = 0.001) were found to be significant independent predictors of in-hospital cardiovascular mortality after adjustment of other risk factors in the multivariate analysis. CONCLUSIONS: fQRS is a simple, inexpensive, and readily available electrocardiographic entity that provides an additional risk stratification level beyond that provided by conventional risk parameters in predicting in-hospital cardiovascular mortality in type 1 AAD.
