We present the case of a 78-year-old woman with a 4.5-cm symptomatic abdominal aortic aneurysm with a small diameter (13-mm diameter) infrarenal aortic neck who underwent endovascular treatment using an iliac branch device as a bifurcated aortic stent-graft.

Penetrating aortic ulcer (PAU) is an acute aortic syndrome that can proceed to life-threatening aortic dissection or even aortic rupture. Isolated iliac aneurysms are relatively rare and often asymptomatic due to their deep pelvic location but are frequently associated with high mortality with rupture. We report a case of a 68-year-old man with a symptomatic penetrating ulcer in the descending aorta and an asymptomatic right iliac aneurysm involving the common and internal iliac arteries. The patient was successfully treated by endovascular repair in a single-stage manner using stent grafts in the descending aorta and right common iliac artery after coil embolization of the right internal iliac artery...

We describe the successful surgical treatment of a 71-year-old man affected by right buttock claudication after a right internal iliac artery (IIA) coil embolization as an adjunct to endovascular iliac artery aneurysm repair. Computed tomography angiography revealed extensive aortoiliac calcifications and thrombus in the vessel walls. Despite patency of the contralateral IIA and preservation of right distal collateral flow through ipsilateral hypogastric branches, the symptom was persistent and disabling. The high-risk patient underwent an "open" repair of the infrarenal abdominal aneurysm with removal of the entire stent-graft and concomitant revascularization of the right IIA...

Purpose: To investigate the association between aortic arch width on frontal chest radiography and systemic hypertension. Methods: A total of 200 consecutive patients were included. Relationships between aortic arch width measurement on chest radiography and blood pressure measurement were investigated using Student's t -tests and Fisher's exact tests. Results: Twenty-five patients were normotensive (< 130/90 mmHg), and 175 were hypertensive...

Smoking increases the risk of abdominal aortic aneurysm (AAA) in both humans and mice, although the underlying mechanisms are not completely understood. An adventitial aortic antigen, AAAP-40, has been partially sequenced. It has motifs with similarities to all three fibrinogen chains and appears to be connected in evolution to a large family of proteins called fibrinogen-related proteins. Fibrinogen may undergo non-enzymatic nitration, which may result from exposure to nitric oxide in cigarette smoke. Nitration of proteins renders them more immunogenic...

Objective: The purpose of this study was to evaluate potential factors affecting patient non-compliance after endovascular aneurysm repair. Method: We performed a retrospective review of patients undergoing elective or emergency endovascular repair for thoracic, abdominal aorta, or iliac artery aneurysm at a single institution from November 2007 to March 2014. Compliance to follow-up at 1, 6, and 12 months was assessed. Factors evaluated included patient demographics, size of aneurysm, distance between the patient's residence and outpatient clinic, urgency of surgery, and time of year in which the follow-up visits were scheduled...

Background: Patients with annuloaortic ectasia may be surgically treated with modified Bentall or David I valve-sparing procedures. Here, we compared the long-term results of these procedures. Methods: A total of 181 patients with annuloaortic ectasia underwent modified Bentall (102 patients, Group 1) or David I (79 patients, Group 2) procedures from 1994 to 2015. Mean age was 62 ± 11 years in Group 1 and 64 ± 16 years in Group 2. Group 1 patients were in poorer health, with a lower ejection fraction and higher functional class...

Background: In procedures involving surgical maneuvers such as cannulation, clamping, or proximal anastomosis where aortic manipulation is inevitable, a preliminary assessment of atherosclerotic plaques bears clinical significance. In the present study, our aim was to evaluate the frequency and distribution of aortic calcifications in patients undergoing coronary artery bypass grafting (CABG) surgery to propose a morphological classification system. Methods: A total of 443 consecutive patients with coronary artery disease were included in this study...

Conventional surgical techniques for acute Type A aortic dissection (ATAAD) generally fail to address residual dissection in the descending aorta. The persistence of a false lumen is associated with visceral malperfusion in the acute setting and adverse aortic remodeling in the chronic setting. Hybrid aortic arch repair techniques may improve perioperative and long-term mortality by expanding the true lumen and obliterating the false lumen. However, there is a limit to the extent of aortic coverage due to the concomitant risk of spinal cord ischemia...

Background: Acute Type A aortic dissection (ATAAD) without end-organ or generalized ischemia is Penn class Aa and considered low-risk. Nevertheless, surgical mortality can be considerable in this subgroup and may be related to modifiable factors. The objective of this study was to analyze 30-day mortality among ATAAD Penn class Aa patients with special reference to modifiable perioperative factors. Methods: Among all patients operated for ATAAD from 1990 to 2010, all Penn class Aa patients dying within 30 days were included in a retrospective descriptive study...

Background: We determined the impact of intraoperative hypothermia on postoperative bleeding after thoracic aortic surgery. Methods: We retrospectively analyzed 98 consecutive patients who underwent aortic surgery with deep hypothermic circulatory arrest between 2010 and 2014. We evaluated lowest temperature, absolute decrease in temperature, and rewarming rate. Univariate and multivariate regression were used to determine relationships between temperature, clinical characteristics, and measures of postoperative bleeding...

A 75-year-old woman was admitted to the emergency department with severe and sudden chest pain. Transthoracic echocardiogram showed an unusual case of aortic dissection Stanford Type A with complete circumferential detachment of the ascending aorta intima. An intussusception of the intima flap into the left ventricular outflow tract was also observed. This case presents a very rare surgical treatment involving root repair using tissue adhesives for a left ventricular intimal flap.

A 63-year-old woman underwent replacement of the aortic root, ascending aorta, and partial arch due to Type A aortic dissection. Shortly thereafter, a replacement of the distal aortic arch and descending aorta was performed. Three years later, the patient developed an aortoesophageal fistula (AEF) resulting in re-replacement of the distal aortic arch and proximal descending aorta with a cryopreserved aortic homograft. Six weeks post-discharge, the patient was readmitted due to recurrent AEF. A thoracic endovascular stent graft was implanted to cover the aortic rupture, followed by correction of an esophageal lesion...

We present the case of a 64-year-old male who presented to the emergency department with bilateral limb ischemia and paralysis for approximately 1 hour. Computed tomographic angiography demonstrated occlusion of the infrarenal aorta beginning just above the patient's known abdominal aortic aneurysm (AAA) and extending into both common iliac arteries. He was emergently treated via open repair of the AAA with a Gore-Tex tube graft, bilateral common iliac thrombectomies, and bilateral lower extremity four-compartment fasciotomies...

Background: Chronic descending thoracic aortic dissection (CDTAD) following surgical repair of ascending aortic dissection requires long-term imaging surveillance. We investigated four-dimensional (4D)-flow magnetic resonance imaging (MRI) with a novel multi-velocity encoding (multi-VENC) technique as an emerging clinical method enabling the dynamic quantification of blood volume and velocity throughout the cardiac cycle. Methods: Patients with CDTAD (n = 10; mean age, 55...

Background: Preoperative coronary angiography is often not performed in acute Type A dissection. We examined differences in the incidence of pre-existing coronary disease and subsequent coronary events between patients undergoing acute Type A dissection repair and patients undergoing elective proximal aortic aneurysm repair. Methods: From 2000 to 2015, there were 154 acute Type A dissection repairs and 457 elective proximal aortic aneurysm repairs. We performed a retrospective review to evaluate preoperative coronary disease and postoperative coronary interventions such as percutaneous coronary intervention (PCI) and coronary bypass grafting (CABG)...
