Pseudoaneurysm is defined as a reperfused pulsatile hematoma, encapsulated and communicated with the damaged vessel's lumen. It originates when there is a disruption of the arterial wall. Hemoptysis is a very rare sign/symptom of a thoracic aortic aneurysm or pseudoaneurysm. There is little information on hemoptysis associated with aortic aneurysm rupture, whose mechanisms are not explained by the presence of an aortopulmonary fistula. Among the hypotheses to explain this phenomenon, is the ability of the bronchial arteries to become hyperplasic and tortuous in the presence of a lesion that modifies the pulmonary architecture, being more susceptible to rupture. There are also descriptions of direct lung parenchymal injury from ruptured aneurysm. The present case illustrates that we must consider the hemoptysis as a warning sign in differential diagnosis of aortic aneurysms and pseudo aneurysms, among other causes, that it can be fatal in a short time due to massive hemorrhage.

Today, abdominal aortic aneurysm surgery is a fairly well-studied area of medicine. Nevertheless, some questions remain rather debatable. No clear criteria for giant aneurysms have been developed so far. The available foreign and domestic literature reports about 40 cases of surgical treatment of giant abdominal aortic aneurysms, 16 of which are cases of aneurysm rupture. Open surgery remains the method of choice in the treatment of giant aneurysms due to the pronounced technical difficulties of endovascular intervention. The authors present a case of successful surgical treatment of a giant aneurysm rupture in an elderly patient. The peculiarity of this patient's condition is the occurrence of aneurysm rupture after hospital admission. The patient refused surgical treatment for two years after aneurysm detection. On examination after admission, multispiral computed tomography revealed an aneurysm size of 101 mm. On the eve of surgery, pain syndrome in the left abdomen and tachycardia appeared. Aneurysm rupture was suspected and the patient was urgently admitted to the operating room. The surgery was performed under the conditions of machine reinfusion of autoblood. The patient underwent abdominal aortic aneurysm resection with linear prosthesis and retroperitoneal hematoma removal. The postoperative period had no peculiarities. On the 10th day after the operation the patient was discharged in satisfactory condition to the outpatient treatment. This clinical case demonstrates the possibility of successful surgical treatment of giant aneurysm rupture in elderly patients.

Endovascular surgery as a whole, and specifically in the context of aortic aneurysms, is a very interesting methodology the potential of which is increasingly being recognized. Follow up information on patients who underwent these procedures will be critical to validate the different techniques which have been developed and to identify the most appropriate situations for this type of surgical procedures. The authors present a case of aortic aneurysm rupture who had undergone Parodi's endoprosthesis placement two years before. CT angiographic evaluation showed a wide endoleak due to distal stent detachment, a complete dislodging of the endoprosthesis itself and retroperitoneal haematoma. Prosthesis replacement through a laparotomic approach was carried out and the patient was discharged 10 days postoperatively, surgically cured.

Background: Whether emphysema is associated with the development and rupture of cerebral and abdominal aortic aneurysms is unclear. Methods and Materials: We performed a retrospective cohort study using outpatient and impatient claims data from a nationally representative 5% sample of Medicare beneficiaries > 66 years of age. Our predictor variable was emphysema and our outcome was a hospitalization for aneurysmal subarachnoid hemorrhage (SAH) or ruptured aortic aneurysm. All predictors and outcomes were defined using previously reported International Classification of Diseases, 9 th Revision, Clinical Modification ( ICD-9-CM ) diagnosis code algorithms. Survival statistics were used to calculate incidence rates and Cox regression was used to measure the association between emphysema and outcomes while adjusting for demographics and previously reported risk factors for aneurysm rupture: hypertension, diabetes, and tobacco and alcohol use. Results: We identified 133,337 patients with emphysema and 1,484,760 patients without emphysema. Over a mean follow-up period of 4.3 (+/-1.9) years, we identified 5,396 cases of aneurysm rupture, 477 of which occurred in patients with emphysema. The annual incidence of aneurysm rupture was 159 (95% confidence interval [CI], 146-174) per 100,000 in patients with emphysema and 74 (95% CI, 72-76) per 100,000 in patients without emphysema. After adjusting for demographics and other risk factors, emphysema was independently associated with aneurysm rupture (hazard ratio [HR], 1.6; 95% CI, 1.4-1.8). In secondary analyses, emphysema was associated with both aneurysmal SAH (HR, 1.4; 95% CI, 1.2-1.6) and ruptured aortic aneurysm (HR, 2.1; 95% CI, 1.7-2.5). Conclusion: Patients with emphysema faced an increased risk of developing SAH and aortic aneurysm rupture. This finding is consistent with the hypothesis that protease/anti-protease imbalance, which is seen in emphysema, may play a role in vessel wall weakening and the development and rupture of aneurysms.

Chronic-contained aortic aneurysm rupture with vertebral erosion is a rare entity with fatal complications. Multidetector computed tomography (CT) angiography is an important diagnostic method for the evaluation of the aortic aneurysms, their complications, and also the relationship between aneurysm and branching vessels and adjacent structures. We present the multidetector CT angiography findings of a 62-year-old patient with chronic-contained thoracoabdominal aortic aneurysm rupture causing severe vertebral body erosion.

Background: Besides biological factors, abdominal aortic aneurysm rupture is also caused by mechanical parameters, which are constantly affecting the wall’s tissue due to their abnormal values. The ability to evaluate these parameters could vastly improve the clinical treatment of patients with abdominal aortic aneurysms. The objective of this study was to develop and demonstrate a methodology to analyze the fluid dynamics that cause the wall stress distribution in abdominal aortic aneurysms, using accurate 3D geometry and a realistic, nonlinear, elastic biomechanical model using a computer-aided software. Methods: The geometry of the abdominal aortic aneurysm; was constructed on a 3D scale using computer-aided software SolidWorks (Dassault Systems SolidWorksCorp., Waltham MA). Due to the complex nature of the abdominal aortic aneurysm geometry, the physiological forces and constraints acting on the abdominal aortic aneurysm wall were measured by using a simulation setup using boundary conditions and initial conditions for different studies such as finite element analysis or computational fluid dynamics. Results: The flow pattern showed an increase velocity at the angular neck, followed by a stagnated flow inside the aneurysm sack. Furthermore, the wall shear stress analysis showed to focalized points of higher stress, the top and bottom of the aneurysm sack, where the flow collides against the wall. An increase of the viscosity showed no significant velocity changed but results in a slight increase in overall pressure and wall shear stress. Conclusions: Conducting computational fluid dynamics modeling of the abdominal aortic aneurysm using computer-aided software SolidWorks (Dassault Systems SolidWorksCorp., Waltham MA) proves to be an insightful approach for the clinical setting. The careful consideration of the biomechanics of the abdominal aortic aneurysm may lead to an improved, case-specific prediction of the abdominal aortic aneurysm rupture potential, which could significantly improve the clinical management of these patients.

The regulation of macrophage recruitment and retention into the vascular wall is critical in the progression of atherosclerosis and aortic aneurysm formation. This can be mediated by chemokine activation of multiple G-protein coupled receptors. The Regulator of G-Protein Signaling-1 (RGS1) acts to deactivate the intracellular response to sustained chemokine stimulation. We have found that RGS1 is upregulated with atherosclerotic plaque progression and with monocyte-macrophage activation but its role is unknown. Rgs1-/- macrophages have significantly enhanced migratory responses to atherogenic chemokines and have impaired desensitization to chemokine re-stimulation (p<0.001). In vivo, RGS1 has a role in the accumulation of macrophages in atherosclerotic lesions and during Angiotensin II (AngII) aortic aneurysm rupture. In the absence of RGS1, atherosclerosis and macrophage accumulation is attenuated in early lesions in the aortic root and aortas of ApoE-/- mice (p<0.001). Rgs1-/- mice are protected from AngII induced aneurysm rupture compared to ApoE-/- mice with 94% survival vs. 56%. Rgs1-/- mice have significantly fewer CD11b+ myeloid cells and CD14+ macrophages in aortas than ApoE-/- mice (p<0.05) after 5 days of AngII infusion. Following bone marrow transplantation, recipient mice receiving ApoE-/- bone marrow were more susceptible to aortic aneurysm rupture (p=0.0124), indicating bone marrow-derived RGS1 is required for aneurysm rupture. Furthermore, AngII treatment increased systolic blood pressure to a greater extent in Rgs1-/- mice than ApoE-/- mice suggesting aneurysm formation in these mice is independent of AngII induced hypertension and this is mediated by vascular-derived RGS1. To gain insight into the mechanism by which RGS1 regulates trafficking, we selectively labelled inflammatory monocytes in vivo to track their movement into aortas following AngII infusion. We found an accumulation of labelled CD45+ cells in the aortas of ApoE-/- mice from day 3 to day 5 but not in Rgs1-/- mice indicating RGS1 as a regulator of macrophage retention in aortic aneurysms. These findings identify a novel role for RGS1 in leukocyte retention in vascular inflammation, highlighting RGS1 as a potential target in cardiovascular disease.

Endovascular abdominal aortic aneurysm repair (EVAR) has experienced a continuous spread worldwide as a result of the constant drive to develop innovative methods and devices that enable physicians to achieve therapeutic aims while reducing procedural risks and patient discomfort. Randomised controlled studies have demonstrated clear early benefits over open repair in terms of mortality and morbidity, but a high reintervention rate jeopardised the EVAR outcome. Complications in EVAR, such as endoleaks, separation of modular components, stent or hook fractures and distal migration of the endograft, can lead to aneurysm enlargement and thus to the native risk of aneurysm rupture. In order to prevent such complications and minimise potential re-interventions, new-generation stent grafts, low-profile delivery systems and new percutaneous closing devices have been developed and adopted, making a totally percutaneous approach possible and desirable. Nevertheless, operators must be aware and trained to face every complication that could possibly develop during and after the procedure. Given these circumstances, EVAR is under consideration as the first line of treatment for abdominal aortic aneurysms.

Left recurrent laryngeal nerve palsy rarely results from cardiac disease. We present 2 cases of left recurrent laryngeal nerve palsy caused by thoracic saccular aortic aneurysms. One patient suffered an aortic aneurysm rupture one month after the advent of hoarseness, necessitating emergency surgery with aortic arch replacement. The other patient underwent elective aortic arch replacement surgery. Both saccular aortic aneurysms protruded downward in the aortopulmonary window to compress the recurrent laryngeal nerves. This is only the 5th case report of the rare occurrence of acute recurrent laryngeal nerve palsy subsequent to saccular aneurysm rupture in the English literature. Recurrent laryngeal nerve palsy does not always indicate imminent aneurysm rupture, but should trigger awareness of a potential rupture in the near future. Left recurrent laryngeal nerve palsy might be a prodrome of aneurysm rupture.

Background and aims: In this study the results of endovascular treatment of aortic aneurysms in Finland are presented and compared to the results of the Eurostar registry. Material and methods: A total of 229 patients with aortic aneurysm were treated in five different Finnish centres during 1996–2000. The data of these patients were collected prospectively by surgeon or interventional radiologist involved. During the same period of time 2464 patients were registered in the Eurostar registry. Results: The procedure was performed successfully in 97 % of patients in Finland, and the 30-day mortality was 0,9 %. A graft limb thrombosis was detected in 9 % of the patients in Finland. A permanent primary endoleak at the first 30-day control was seen in 23 patients (10 %). During the follow-up 17 secondary endoleaks (7 %) were detected. A secondary intervention was necessary in 26 % of the patients. Three patients (1.3 %) had late rupture of the abdominal aortic aneurysm. Conclusions: According to the Finnish short-time results, endovascular treatment of aortic aneurysms is safe and associated with relatively low morbidity and mortality. The mid-term results are more disappointing with relatively many graft thromboses and endoleaks, and a frequent need of secondary interventions.
