It is performed by joining two arteries (direct anastomosis or use of graft) or by free autologous transplantation of highly vascularized tissue to the surface of the brain.Drainage: The removal of fluids or discharges from the body, such as from a wound, sore, or cavity.Matrix Metalloproteinase 12: A secreted matrix metalloproteinase which is highly expressed by MACROPHAGES where it may play a role in INFLAMMATION and WOUND HEALING.Mucocutaneous Lymph Node Syndrome: An acute, febrile, mucocutaneous condition accompanied by swelling of cervical lymph nodes in infants and young children. The principal symptoms are fever, congestion of the ocular conjunctivae, reddening of the lips and oral cavity, protuberance of tongue papillae, and edema or erythema of the extremities.Aortic Valve: The valve between the left ventricle and the ascending aorta which prevents backflow into the left ventricle.Thoracotomy: Surgical incision into the chest wall.Prosthesis-Related Infections: Infections resulting from the implantation of prosthetic devices. The infections may be acquired from intraoperative contamination (early) or hematogenously acquired from other sites (late).Comorbidity: The presence of co-existing or additional diseases with reference to an initial diagnosis or with reference to the index condition that is the subject of study. Comorbidity may affect the ability of affected individuals to function and also their survival; it may be used as a prognostic indicator for length of hospital stay, cost factors, and outcome or survival.Cohort Studies: Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesized to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics.Reproducibility of Results: The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.Aortic Valve Insufficiency: Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).Colitis, Ischemic: Inflammation of the COLON due to colonic ISCHEMIA resulting from alterations in systemic circulation or local vasculature.Models, Anatomic: Three-dimensional representation to show anatomic structures. Models may be used in place of intact animals or organisms for teaching, practice, and study.Endoscopy: Procedures of applying ENDOSCOPES for disease diagnosis and treatment. Endoscopy involves passing an optical instrument through a small incision in the skin i.e., percutaneous; or through a natural orifice and along natural body pathways such as the digestive tract; and/or through an incision in the wall of a tubular structure or organ, i.e. transluminal, to examine or perform surgery on the interior parts of the body.Systemic Inflammatory Response Syndrome: A systemic inflammatory response to a variety of clinical insults, characterized by two or more of the following conditions: (1) fever >38 degrees C or HYPOTHERMIA 90 beat/minute; (3) tachypnea >24 breaths/minute; (4) LEUKOCYTOSIS >12,000 cells/cubic mm or 10% immature forms. While usually related to infection, SIRS can also be associated with noninfectious insults such as TRAUMA; BURNS; or PANCREATITIS. If infection is involved, a patient with SIRS is said to have SEPSIS.Vertebral Artery Dissection: Splitting of the vessel wall in the VERTEBRAL ARTERY. Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the vertebral artery, aneurysm formation, or THROMBOEMBOLISM. Vertebral artery dissection is often associated with TRAUMA and injuries to the head-neck region but can occur spontaneously.Postoperative Period: The period following a surgical operation.Cardiopulmonary Bypass: Diversion of the flow of blood from the entrance of the right atrium directly to the aorta (or femoral artery) via an oxygenator thus bypassing both the heart and lungs.Carotid Artery, Internal, Dissection: The splitting of the vessel wall in one or both (left and right) internal carotid arteries (CAROTID ARTERY, INTERNAL). Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the internal carotid artery and aneurysm formation.Registries: The systems and processes involved in the establishment, support, management, and operation of registers, e.g., disease registers.Sex Factors: Maleness or femaleness as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or effect of a circumstance. It is used with human or animal concepts but should be differentiated from SEX CHARACTERISTICS, anatomical or physiological manifestations of sex, and from SEX DISTRIBUTION, the number of males and females in given circumstances.Carotid Artery, Common: The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (CAROTID ARTERY, EXTERNAL) and internal (CAROTID ARTERY, INTERNAL) carotid arteries.Postoperative Hemorrhage: Hemorrhage following any surgical procedure. It may be immediate or delayed and is not restricted to the surgical wound.Magnetic Resonance Imaging: Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.Mechanical Thrombolysis: Procedures to cause the disintegration of THROMBI by physical interventions.Peripheral Vascular Diseases: Pathological processes involving any one of the BLOOD VESSELS in the vasculature outside the HEART.Biological Markers: Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, environmental exposure and its effects, disease diagnosis, metabolic processes, substance abuse, pregnancy, cell line development, epidemiologic studies, etc.Equipment Failure Analysis: The evaluation of incidents involving the loss of function of a device. These evaluations are used for a variety of purposes such as to determine the failure rates, the causes of failures, costs of failures, and the reliability and maintainability of devices.Psoas Abscess: Abscess of the PSOAS MUSCLES resulting usually from disease of the lumbar vertebrae, with the pus descending into the muscle sheath. The infection is most commonly tuberculous or staphylococcal.Myocytes, Smooth Muscle: Non-striated, elongated, spindle-shaped cells found lining the digestive tract, uterus, and blood vessels. They are derived from specialized myoblasts (MYOBLASTS, SMOOTH MUSCLE).Hematoma: A collection of blood outside the BLOOD VESSELS. Hematoma can be localized in an organ, space, or tissue.
Intimal tear without hematoma: an important variant of aortic dissection that can elude current imaging techniques. (1/1306)BACKGROUND: The modern imaging techniques of transesophageal echocardiography, CT, and MRI are reported to have up to 100% sensitivity in detecting the classic class of aortic dissection; however, anecdotal reports of patient deaths from a missed diagnosis of subtle classes of variants are increasingly being noted. METHODS AND RESULTS: In a series of 181 consecutive patients who had ascending or aortic arch repairs, 9 patients (5%) had subtle aortic dissection not diagnosed preoperatively. All preoperative studies in patients with missed aortic dissection were reviewed in detail. All 9 patients (2 with Marfan syndrome, 1 with Takayasu's disease) with undiagnosed aortic dissection had undergone >/=3 imaging techniques, with the finding of ascending aortic dilatation (4.7 to 9 cm) in all 9 and significant aortic valve regurgitation in 7. In 6 patients, an eccentric ascending aortic bulge was present but not diagnostic of aortic dissection on aortography. At operation, aortic dissection tears were limited in extent and involved the intima without extensive undermining of the intima or an intimal "flap." Eight had composite valve grafts inserted, and all survived. Of the larger series of 181 patients, 98% (179 of 181) were 30-day survivors. CONCLUSIONS: In patients with suspected aortic dissection not proven by modern noninvasive imaging techniques, further study should be performed, including multiple views of the ascending aorta by aortography. If patients have an ascending aneurysm, particularly if eccentric on aortography and associated with aortic valve regurgitation, an urgent surgical repair should be considered, with excellent results expected.

Pathogenetic sequence for aneurysm revealed in mice underexpressing fibrillin-1. (2/1306)Dissecting aortic aneurysm is the hallmark of Marfan syndrome (MFS) and the result of mutations in fibrillin-1, the major constituent of elastin-associated extracellular microfibrils. It is yet to be established whether dysfunction of fibrillin-1 perturbs the ability of the elastic vessel wall to sustain hemodynamic stress by disrupting microfibrillar assembly, by impairing the homeostasis of established elastic fibers, or by a combination of both mechanisms. The pathogenic sequence responsible for the mechanical collapse of the elastic lamellae in the aortic wall is also unknown. Targeted mutation of the mouse fibrillin-1 gene has recently suggested that deficiency of fibrillin-1 reduces tissue homeostasis rather than elastic fiber formation. Here we describe another gene-targeting mutation, mgR, which shows that underexpression of fibrillin-1 similarly leads to MFS-like manifestations. Histopathological analysis of mgR/mgR specimens implicates medial calcification, the inflammatory-fibroproliferative response, and inflammation-mediated elastolysis in the natural history of dissecting aneurysm. More generally, the phenotypic severity associated with various combinations of normal and mutant fibrillin-1 alleles suggests a threshold phenomenon for the functional collapse of the vessel wall that is based on the level and the integrity of microfibrils.

Observations on the treatment of dissection of the aorta. (3/1306)The results are presented of treatment in twenty-three patients with dissection of the thoracic aorta, in four of whom it was acute (less than 14 days' duration), and in nineteen chronic (more than 14 days' duration). Sixteen patients had Type I and II dissection (involving the ascending aorta) and five Type III (descending aorta at or distal to the origin of the left subclavian artery); in two, dissection complicated coarctation of the aorta in the usual site. Thirteen patients had aortic regurgitation. Three of the patients with acute dissection were treated medically; two, both with Type I dissection, died, and the third, with Type III, survived. The remaining acute patient was treated surgically and also died. Of the patients with chronic dissection, eight were treated medically and eleven surgically. None of the medical group died in hospital; three died between 3 months and 1 year, and five have survived from periods of 12-72 months. Eleven patients with chronic dissection were treated surgically; four died in hospital at or shortly after operation; and the remaining seven lived for periods of 12-84 months. The presentation, indications for surgical treatment and results are discussed. It is concluded that surgical treatment of chronic dissection may carry a higher initial mortality than medical, but that there may be slightly better overall long term results in the former. As this series was not selected randomly, because patients with complications were selected for surgery, and there are only a few patients in each group, the results do not permit firm conclusion regarding the relative merits of medical and surgical treatment. It is suggested that all patients should initially be treated medically but that surgical treatment should be considered if the dissection continues, if aortic regurgitation is severe, if an aneurysm develops or enlarges, if cardiac tamponade develops or there is evidence of progressive involvement of the branches of the aorta. Attention is drawn to the important syndrome of chronic dissecting aneurysm of the ascending aorta with severe aortic regurgitation which requires definitive surgical treatment and aortic valve replacement. The importance of adequate visualization of the origin and extent of the dissection as a preliminary to surgical treatment is stressed. (+info)
Replacement of the aortic root in patients with Marfan's syndrome. (4/1306)BACKGROUND: Replacement of the aortic root with a prosthetic graft and valve in patients with Marfan's syndrome may prevent premature death from rupture of an aneurysm or aortic dissection. We reviewed the results of this surgical procedure at 10 experienced surgical centers. METHODS: A total of 675 patients with Marfan's syndrome underwent replacement of the aortic root. Survival and morbidity-free survival curves were calculated, and risk factors were determined from a multivariable regression analysis. RESULTS: The 30-day mortality rate was 1.5 percent among the 455 patients who underwent elective repair, 2.6 percent among the 117 patients who underwent urgent repair (within 7 days after a surgical consultation), and 11.7 percent among the 103 patients who underwent emergency repair (within 24 hours after a surgical consultation). Of the 675 patients, 202 (30 percent) had aortic dissection involving the ascending aorta. Forty-six percent of the 158 adult patients with aortic dissection and a documented aortic diameter had an aneurysm with a diameter of 6.5 cm or less. There were 114 late deaths (more than 30 days after surgery); dissection or rupture of the residual aorta (22 patients) and arrhythmia (21 patients) were the principal causes of late death. The risk of death was greatest within the first 60 days after surgery, then rapidly decreased to a constant level by the end of the first year. CONCLUSIONS: Elective aortic-root replacement has a low operative mortality. In contrast, emergency repair, usually for acute aortic dissection, is associated with a much higher early mortality. Because nearly half the adult patients with aortic dissection had an aortic-root diameter of 6.5 cm or less at the time of operation, it may be prudent to undertake prophylactic repair of aortic aneurysms in patients with Marfan's syndrome when the diameter of the aorta is well below that size.

Endovascular stent-graft placement for the treatment of acute aortic dissection. (5/1306)BACKGROUND: The standard treatment for acute aortic dissection is either surgical or medical therapy, depending on the morphologic features of the lesion and any associated complications. Irrespective of the form of treatment, the associated mortality and morbidity are considerable. METHODS: We studied the placement of endovascular stent-grafts across the primary entry tear for the management of acute aortic dissection originating in the descending thoracic aorta. We evaluated the feasibility, safety, and effectiveness of transluminal stent-graft placement over the entry tear in 4 patients with acute type A aortic dissections (which involve the ascending aorta) and 15 patients with acute type B aortic dissections (which are confined to the descending aorta). Dissections involved aortic branches in 14 of the 19 patients (74 percent), and symptomatic compromise of multiple branch vessels was observed in 7 patients (37 percent). The stent-grafts were made of self-expanding stainless-steel covered with woven polyester or polytetrafluoroethylene material. RESULTS: Placement of endovascular stent-grafts across the primary entry tears was technically successful in all 19 patients. Complete thrombosis of the thoracic aortic false lumen was achieved in 15 patients (79 percent), and partial thrombosis was achieved in 4 (21 percent). Revascularization of ischemic branch vessels, with subsequent relief of corresponding symptoms, occurred in 76 percent of the obstructed branches. Three of the 19 patients died within 30 days, for an early mortality rate of 16 percent (95 percent confidence interval, 0 to 32 percent). There were no deaths and no instances of aneurysm or aortic rupture during the subsequent average follow-up period of 13 months. CONCLUSIONS: These initial results suggest that stent-graft coverage of the primary entry tear may be a promising new treatment for selected patients with acute aortic dissection. This technique requires further evaluation, however, to assess its therapeutic potential fully. (+info)
The highs and lows of endovascular aneurysm repair: the first two years of the Eurostar Registry. (6/1306)The Eurostar Registry was established in 1996 to collate information, from centres across Europe, on the outcome from endovascular grafting of aortic aneurysms. At the end of the first year of the project, data on 430 patients had been entered onto the database. In 420 patients (97.7%), the endografts were deployed without major complications. The 30-day mortality rate was low at 3.4% and deaths were confined mostly to 'high risk' patients with major co-morbidity. Endoleaks, which were present on discharge from hospital in 15.7% of patients, were associated with a significantly increased incidence of continued expansion of the aneurysm sac postoperatively (P < 0.01). Thus the early results confirmed the feasibility and low complication rate of endovascular repair of aneurysms, but a higher than expected incidence of endoleaks. At 2 years, 895 patients had been registered. The rate of early endoleaks remained significantly unchanged but another 18% of patients had developed new endoleaks during the first year of follow-up. Six delayed ruptures had been reported, 3 fatal. There were indications that 'self sealed' endoleaks continued to pressurise the aneurysm sac. Severe distortion of the grafts with kinking and other structural changes associated with postoperative longitudinal shrinking of the aneurysm sac was observed in 69% of patients at 1 year. Clinical complications associated with these changes included late endoleak and graft limb occlusion. Early unrealistic optimism about endovascular aneurysm repair has been replaced with a more realistic understanding of its benefits and limitations as a result of the Eurostar project and other registries. Randomised studies are now required to establish the most appropriate role for this approach, alongside established therapies. (+info)
Increased chymase-dependent angiotensin II formation in human atherosclerotic aorta. (7/1306)Locally formed angiotensin II (Ang II) and mast cells may participate in the development of atherosclerosis. Chymase, which originates from mast cells, is the major Ang II-forming enzyme in the human heart and aorta in vitro. The aim of the present study was to investigate aortic Ang II-forming activity (AIIFA) and the histochemical localization of each Ang II-forming enzyme in the atheromatous human aorta. Specimens of normal (n=9), atherosclerotic (n=8), and aneurysmal (n=6) human aortas were obtained at autopsy or cardiovascular surgery from 23 subjects (16 men, 7 women). The total, angiotensin-converting enzyme (ACE)-dependent, and chymase-dependent AIIFAs in aortic specimens were determined. The histologic and cellular localization of chymase and ACE were determined by immunocytochemistry. Total AIIFA was significantly higher in atherosclerotic and aneurysmal lesions than in normal aortas. Most of AIIFA in the human aorta in vitro was chymase-dependent in both normal (82%) and atherosclerotic aortas (90%). Immunocytochemical staining of the corresponding aortic sections with antichymase, antitryptase or anti-ACE antibodies showed that chymase-positive mast cells were located in the tunica adventitia of normal and atheromatous aortas, whereas ACE-positive cells were localized in endothelial cells of normal aorta and in macrophages of atheromatous neointima. The density of chymase- and tryptase-positive mast cells in the atherosclerotic lesions was slightly but not significantly higher than that in the normal aortas, and the number of activated mast cells in the aneurysmal lesions (18%) was significantly higher than in atherosclerotic (5%) and normal (1%) aortas. Our results suggest that local Ang II formation is increased in atherosclerotic lesions and that chymase is primarily responsible for this increase. The histologic localization and potential roles of chymase in the development of atherosclerotic lesions appear to be different from those of ACE. (+info)
Effect of nitrous oxide on myogenic motor potentials evoked by a six pulse train of transcranial electrical stimuli: a possible monitor for aortic surgery. (8/1306)Intraoperative recording of myogenic motor potentials evoked by transcranial electrical stimulation (tcMEP) is a method of monitoring the integrity of the vulnerable motor pathways during thoracoabdominal aortic aneurysm (TAAA) surgery. Deflation of the left lung during TAAA surgery may result in impairment of arterial oxygenation. Ventilation with nitrous oxide may cause further desaturation. We studied the effects of 20%, 40% and 60% nitrous oxide in oxygen on within-patient variability and magnitude of tcMEP in response to six pulse transcranial electrical stimulation during fentanyl-low-dose propofol anaesthesia with partial neuromuscular block. Ten patients (two females; aged 63-74 yr) were studied. After achieving a stable anaesthetic state and before surgery, 10 tcMEP were recorded from the right tibialis anterior muscle during addition of 20%, 40% and 60% nitrous oxide in oxygen in random order. When ventilation with 40% or 60% nitrous oxide in oxygen was performed, there was 50-70% depression of tcMEP amplitude (P < 0.05) and 40-60% reduction in tcMEP area under the curve (P < 0.05) compared with 20% nitrous oxide in oxygen. There was no significant difference in the coefficients of variation for tcMEP between the three nitrous oxide anaesthetic regimens. Our results suggest that increasing doses of nitrous oxide reduce the MEP waveform to six pulse transcranial electrical stimulation, but even with 60% nitrous oxide in oxygen, the tcMEP were recordable and as reproducible as with 20% and 40% nitrous oxide regimens. The method is sufficiently robust for use in aortic surgery. (+info)
Aortic Root Reconstruction | IntechOpen
Aortic root reconstruction represents one of the most complex areas of cardiac surgery as well as one of the most dynamic-major developments in understanding of the aortic root anatomy and physiology, improvements in imaging and surgical technique allowed for development and acceptance into clinical practice of several novel procedures over last couple of decades. From first aortic root replacement reported by Bentall and De Bono in 1968 to aortic root reimplantation (David procedure) and remodeling (Yacoub operation) with multiple contemporary modifications, aortic root reconstruction now is widely used in treatment of chronic aortic aneurysmal disease and acute aortic dissections alike. Basic principles of aortic root structure and function and critical operative strategies for aortic root surgery are reviewed in this chapter.

Variation in the histopathological features of patients with ascending aortic aneurysms: a study of 111 surgically excised...
Background: Ascending aortic aneurysms (AA) are a common, though poorly understood medical condition.. Aims: To document the histological changes in a large series of human ascending AA, and to correlate these changes with clinical variables.. Methods: 111 ascending AA were excised at surgery over a 3 year period. Each aneurysm was received as a continuous ring of tissue. Sections were taken from the anterior, posterior, greater and lesser curvature of the aorta and graded in a semi-quantitative fashion for the degree of elastin fragmentation, elastin loss, smooth muscle cell (SMC) loss, intimal changes and inflammation.. Results: Mean patient age at surgery was 58.7 (15.6) years; there were 70 men and 41 women. 12 patients had Marfan syndrome, 34 (30.6%) had a bicuspid aortic valve (BAV), while 71 (64.0%) had a tricuspid aortic valve (TAV). Inflammatory cells were present in 28 cases (25.2%) and were confined to the adventitia. No particular region of the aortic circumference was more severely ...
Surgical Management of Descending Thoracic Aortic Disease: Open and Endovascular Approaches | Circulation
Understanding the pathogenesis of aortic dissection requires consideration of the inciting event that causes the intimal-medial tear and the propagation of blood within the aortic media. Although various risk factors that predispose the aorta to dissection have been described well, the precise insult that leads to laceration of the intima and media remains unclear.. Historically, the primary causative event that leads to aortic dissection has been extremely controversial. Cystic medial necrosis associated with Marfan disease and other connective tissue disorders was once believed to contribute to aortic medial degeneration, leading to aortic dissection. Larson and Edwards,42 however, demonstrated that only a few of their 161 patients with known aortic dissection exhibited medial degeneration. They found that 158 of these patients had intimal aortic tears at autopsy, which supports the theory initially proposed by Murray and Edwards43 that the intimal tear is the primary event, allowing the blood ...

I just returned from my first visit with the cardio/thoracic surgeon. He gave me good news that my ascending aortic aneurysm is 3.9 and technically not at the 4.0 stage for a true aneurysm. But I will get the echo cardio gram and another CAT scan in a year to see if it is stable. He assured me that there really is only a 3% chance of it rupturing at this level. And of course as the centimeters increase so does the chances. But they still do not do surgery until 6 cm because there is a greater risk of rupture than the surgery. So I am content to just get my yearly screenings and he said there is a great chance that I will never be operated on but you have to be vigilant with your check ups.

Results Total hospital (30-day) mortality was 4% (n = 2). 2(4%) patients required reoperation due to post-operative bleeding. Echocardiography showed none or trivial AI in 38%, mild AI in 54% and moderate AI in 8%. We revealed positive correlation between residual AI and size of aortic annulus, previous AI grade, and size of aortic prosthesis (optimal result in linear aortic graft size 3-5 mm exceeding aortic annulus size). Follow-up was 60% completed. Late mortality was 2% (1 patient). Echocardiography revealed none or trivial AI in 53%, mild AI in 20%, moderate AI in 17% and severe AI in 10% (3 patients). One patient required reoperation 3 years after TD-I operation, the AV replacement with mechanical prosthesis was performed. Another two patients with severe AI are under close surveillance due to normal LV size and NYHA class 1-2. We revealed positive correlation between late AI and residual AI grade, and aortic leaflets coaptation point (optimal result in cases with location of coaptation ...

Medial degeneration associated with thoracic aortic aneurysm and acute aortic dissection was originally described by Erdheim as a noninflammatory lesion related to the loss of smooth muscle cells and elastic fibre fragmentation in the media. Recent evidences propose the strong role of a chronic immune/inflammatory process in aneurysm evocation and progression. The coexistence of inflammatory cells with markers of apoptotic vascular cell death in the media of ascending aorta with aneurysms and type A dissections raises the possibility that activated T cells and macrophages may contribute to the elimination of smooth muscle cells and degradation of the matrix ...
Evaluation of the intraoperative specimens of the thoracic and abdominal aorta | Journal of Cardiothoracic Surgery | Full Text
Medial degeneration was the most frequent diagnosis in this series of aortic specimens. Medial degeneration was equally common in patients above and below 65 years of age. However, in cases with acute type A aortic dissections, high grade atherosclerosis was the leading histopathological diagnosis in patients older than 65 years. Acute type A aortic dissections seem to have different underlying pathologies in different age groups.. This series represents a one-year volume of an aortic referral center. The intention of this analysis was to correlate histopathological to morphological findings from imaging as well as to raise our intraoperative macroscopic and subjective impressions to a microscopic and objective level.. According to the risk factors a height prevalence of hypertension was observed in all of the patient groups. Especially the TAD group ≥ 65 years of age showed a relatively high rate of hypertension with no clinical diagnosis of connective tissue disease in this group. Generally, ...

Recently, however, it was advocated that patients who had type B acute aortic dissection without complications, such as rupture or organ ischemia, be treated with hypotensive drugs during the acute phase, because the mortality rate with this treatment is reported to be equal to or slightly better than that for surgical treatment during the acute phase.4 5 12 13 14 15 16 17 Surgical treatment should be selected if the aortic diameter becomes enlarged during the chronic phase; careful observation of aortic enlargement in all patients treated during the chronic phase is very important but very difficult. Unfortunately, some patients who have successfully gone through the acute phase with medical hypotensive therapy suddenly die during ...

The Risk for Type B Aortic Dissection in Marfan Syndrome | JACC: Journal of the American College of Cardiology
In this study, we provide a contemporary overview of clinical outcomes in patients with known MFS without prior aortic dissection. This represents one of the largest MFS studies to date using 3-dimensional imaging techniques. We found a type B aortic dissection rate of 9% during a median follow-up period of 6 years. Type B aortic dissections generally occurred in mildly dilated proximal descending aortas, especially in patients with prior prophylactic aortic surgery. From our data, we were able to develop a risk score to predict type B aortic dissection in patients with MFS, on the basis of history of prophylactic aortic root surgery and proximal descending aortic diameter.. The occurrence of type A aortic dissection has become a rare event in patients with known MFS in the era of aggressive prophylactic surgery. Although AoRR has improved life expectancy considerably, distal aortic disease may develop later in patients with MFS (14,15). Replacement of the aortic root or ascending aorta with a ...

The introduction of composite graft repair of aortic root aneurysm by Hugh Bentall in 1968 promised Marfan patients the choice for a normal life expectancy. We performed our first Bentall composite graft procedure in 1976 and herein report our 24-year experience with 271 Marfan patients. Methods. Between September 1976 and August 2000, 232 Marfan patients had a composite graft replacement of the aortic root, 15 patients received a homograft, and 24 had a valve-sparing procedure. Results. Two hundred thirty-five Marfan patients underwent elective aortic root replacement with no 30-day mortality. Two early deaths occurred among 36 patients who underwent urgent or emergent operation. Eighty-three percent of ...
LOX Mutations Predispose to Thoracic Aortic Aneurysms and DissectionsNovelty and Significance | Circulation Research
The data presented here support the conclusion that heterozygous loss-of-function mutations in LOX, specifically variants that disrupt the catalytic activity or lead to haploinsufficiency, predispose to thoracic aortic aneurysms and acute aortic dissections. Overlapping syndromic features of Marfan syndrome, such as pectus deformities and striae, were reported in family members with LOX variants, but these features were not sufficient to meet diagnostic criteria for Marfan syndrome.13 Thoracic aortic aneurysms in these individuals are either aortic root aneurysms or fusiform aneurysms, involving both the aortic root and ascending aorta. Although mutation carriers died of ascending aortic dissections, there were no reports of aortic dissections with minimal enlargement of the ascending aorta. None of the affected individuals presented with descending thoracic aortic aneurysms or dissections. Interestingly, a bicuspid aortic valve was identified in 3 of 18 individuals with LOX mutations. It is ...
Stent Grafting of Dissected Descending Aorta in Patients With Marfan's Syndrome | JACC: Cardiovascular Interventions
In patients with Marfans syndrome, AD with rupture has long been the main cause of death, even in younger patients. Modern surgical techniques of ascending aortic repair have been essential for improving patient prognoses. Bentall procedures or aortic root reconstruction are currently electively performed with acceptable morbidity and mortality rates.. Unlike in aortic root surgery, which is well codified and may be routinely performed on patients with Marfans syndrome, management of the dissected DTA is still challenging. This is especially true in cases involving aneurysmal dilatation (1,4,14). In contrast with the excellent surgical results of elective root replacement, both early and long-term results of repeat surgery for the descending aorta remain poor (15). De Olivera et al. (16) reported on 6 surgical repairs of the DTA after previous valve-sparing operations. In this series, 3 patients died after surgical repair of the descending aorta, 1 sustained post-operative paraplegia, and 2 ...
Aortic dissection in pregnancy in England: an incidence study using linked national databases | BMJ Open
Aortic dissection, though rare, is an often fatal event.1 A recent population-based study from Oxford showed that women have higher mortality from aortic dissection and are more likely to die before hospital assessment,2 which was also shown by the worlds largest registry of aortic dissection.3 Importantly, most individuals with aortic dissection had inadequately controlled hypertension, suggesting that modifiable risk factors may play a role in prevention.2 Moreover, women have worse outcomes following surgery for aortic dissection,3 and the surgical risk is even higher during pregnancy.4 ,5 The majority of aortic dissections in women of childbearing age occur during pregnancy and have adverse consequences for the mother and the fetus.6 Data from the Swedish National Birth Registry in women ,40 years of age have shown that pregnancy is associated with a 25-fold increased risk of aortic dissection.6 The scientific literature regarding aortic dissection and pregnancy is largely made up of case ...

How does the ascending aorta geometry change when it dissects? - Zurich Open Repository and Archive
OBJECTIVES The purpose of this study is to delineate changes in aortic geometry and diameter due to dissection. BACKGROUND Aortic diameter is the major criterion for elective ascending aortic replacement for dilated ascending aortas to prevent aortic dissection. However, recommendations are made on the basis of clinical experience and observation of diameters of previously dissected aortas. METHODS Six tertiary centers on 2 continents reviewed their acute aortic dissection type A databases, which contained 1,821 patients. Included were all non-Marfan patients with nonbicuspid aortic valves who had undergone computed tomography angiography ,2 years before and within 12 h after aortic dissection onset. Aortic geometry before and after dissection onset were compared. RESULTS Altogether, 63 patients were included (27 spontaneous and 36 retrograde dissections, median age 68 [57; 77] years; 54% were men). In all but 1 patient, maximum ascending aortic diameter was ,55 mm before aortic dissection ...

A Case of Acute Type A Aortic Dissection Complicated with Cerebral Malperfusion
A 59-year-old man with a history of hypertension who suddenly developed back pain and apoplexy was transferred to our hospital 20 min after the clinical onset. Physical examination showed right conjugate deviation of the eyes and left paralysis, suggesting disorder of the right cerebral hemisphere. Enhance computed tomography showed an aortic dissection from the ascending aorta to bilateral iliac arteries, and the right common cranial artery was compressed by a false lumen. Acute type A aortic dissection complicated with cerebral malperfusion was diagnosed, and an emergency operation was performed 2.5h after the onset. Cardiopulmonary bypass was established with right femoral artery inflow and bicaval venous drainage. We found the dissection entry at the ascending aorta using the distal open technique, and performed hemiarch graft replacement with selective cerebral perfusion. The postoperative course was uneventful without deterioration of neurological function. Postoperative computed ...

Acute aortic dissection: be aware of misdiagnosis | BMC Research Notes | Full Text
Acute aortic dissection (AAD) is a life-threatening condition requiring immediate assessment and therapy. A patient suffering from AAD often presents with an insignificant or irrelevant medical history, giving rise to possible misdiagnosis. The aim of this retrospective study is to address the problem of misdiagnosing AD and the different imaging studies used. From January 2000 to December 2004, 49 patients (41 men and 8 women, aged from 18-75 years old) presented to the Emergency Department of our hospital for different reasons and finally diagnosed with AAD. Fifteen of those patients suffered from arterial hypertension, one from giant cell arteritis and another patient from Marfans syndrome. The diagnosis of AAD was made by chest X-ray, contrast enhanced computed tomography (CT), transthoracic echocardiography (TTE) and coronary angiography. Initial misdiagnosis occurred in fifteen patients (31%) later found to be suffering from AAD. The misdiagnosis was myocardial infarction in 12 patients and

Acute aortic dissection: a missed diagnosis | BMJ Case Reports
A 60-year-old man with a history of indigestion and untreated hypertension presented with sudden-onset central chest pain which radiated to his back. Acute coronary syndrome was initially suspected but excluded in the emergency department before the patient was discharged. The pain subsequently abated to mild intermittent episodes and was misdiagnosed as indigestion. A week later the patient developed new shortness of breath and flu-like symptoms with a positive d-dimer test. CT angiography revealed a Stanford type B aortic dissection which was causing hypoperfusion of the right kidney, resulting in an acute kidney injury. Due to uncontrolled hypertension despite rigorous antihypertensive medication and his failing renal function, the patient underwent endovascular repair and made a good recovery postoperatively. ...

Number 09-11: Gerbode Ventricular Septal Defect after Ross Procedure - Society for Cardiovascular Magnetic Resonance
Perspective: Left ventricle-right atrium (LV-RA) communication is mostly congenital and extremely rare (,1% of all congenital heart disease) finding. This was first classified by Gerbode et al. in 1958(1,2). Acquired LV-RA communications can be secondary to endocarditis, trauma, myocardial infarction (1) or valve replacement (1,3). This defect was likely a postoperative complication of the Ross procedure. Cardiac MR imaging was able to show the type and location of the defect, and to help quantify the degree of shunt across the defect (4). References:. 1. Cheema OM, Patel AA, Chang SM, Dipan JS.

Aortic Root Surgery: Medical Procedure, Preparation & Definitions | FindATopDoc
Aortic dissection - Wikipedia
Aortic dissection (AD) occurs when an injury to the innermost layer of the aorta allows blood to flow between the layers of the aortic wall, forcing the layers apart. In most cases this is associated with a sudden onset of severe chest or back pain, often described as "tearing" in character. Also, vomiting, sweating, and lightheadedness may occur. Other symptoms may result from decreased blood supply to other organs such as stroke or mesenteric ischemia. Aortic dissection can quickly lead to death from not enough blood flow to the heart or rupture of the aorta. Aortic dissection is more common in those with a history of high blood pressure, a number of connective tissue diseases that affect blood vessel wall strength such as Marfan syndrome, a bicuspid aortic valve, and previous heart surgery. Major trauma, smoking, cocaine use, pregnancy, a thoracic aortic aneurysm, inflammation of arteries, and abnormal lipid levels are also associated with an increased risk. The diagnosis is suspected based ...

Blood test on horizon to detect aortic aneurysm, dissection - Healthcanal.com : Healthcanal.com
The aorta is the large artery that carries blood away from the heart. Aortic aneurysms and dissections, which often have symptoms similar to a heart attack, cause more than 10,000 deaths annually in the U.S., according to the Centers for Disease Control. Certain types of dissections (Type A), if left untreated, kill 33% of patients within the first 24 hours, and 50% of patients within 48 hours, according to research by the International Registry of Acute Aortic Dissections (IRAD). The research from Shriners Hospital for Children and Oregon Health & Science University, Portland, and Baylor College of Medicine and the Texas Heart Institute in Houston, which was published online today by Circulation Research, found that high blood levels of fibrillin-1, a protein essential to the make-up of the bodys connective tissue and blood vessels, are about twice as common in people with thoracic aortic aneurysm than in people with other types of aortic aneurysms. The high fibrillin-1 levels most likely are ...
132311 | Stanford Health Care
BACKGROUND: Over the past two decades elective valve-sparing aortic root replacement (V-SARR) has become more common in the treatment of patients with aortic root and ascending aortic aneurysms. Currently there are little data available to predict complications in the post-operative population. The study goal was to determine if altered flow patterns in the thoracic aorta, as measured by MRI, are associated with complications after V-SARR. METHODS: Time-resolved three-dimensional phase-contrast MRI (4D flow) was used to image 12 patients with Marfan syndrome after V-SARR. The patients were followed up for an average of 5.8years after imaging and 8.2years after surgery. Additionally 5 volunteers were imaged for comparison. Flow profiles were visualized during peak systole using streamlines. Wall shear stress estimates and normalized flow displacement were evaluated at multiple planes in the thoracic aorta. RESULTS: During the follow-up period, a single patient developed a Stanford Type B aortic ...

Best management of short abdominal aortic aneurysm necks to be highlighted in the CX Abdominal Aortic sessions - CX Symposium
Management of ruptured abdominal aortic aneurysms. The latest evidence on the best way to manage a ruptured aneurysm will be presented including the one-year results of the IMPROVE trial and the IPD 3 trial. In the same session, the controversy as to whether many patients with ruptured abdominal aortic aneurysms are denied intervention will be discussed. Greenhalgh comments: "Perhaps doctors are becoming more concerned about operating for fear of having poor mortality figures. We need to find evidence whether indeed patients are denied intervention.". Janet Powell (Imperial College, London, UK), member of the CX Programme Organising Board, considers that a few patients are offered repair of ruptured aortic aneurysm because perhaps "not all centres have an endovascular team and facilities available at all times; additionally, there are financial stringencies on healthcare systems and many of these patients may need intervention out of hours." Holden adds that many questions on this subject remain ...

We present a successful case of catheter-directed infusion into the SMA for a patient with NOMI complicated with traumatic type B AD involving the SMA. Vasodilator infusion via arterial catheter has been reported as an effective treatment for NOMI and many reports suggested efficacy of this strategies [4-7]. In 1977, Boley et al. decreased mortality rate from about 70-80% to 40% performing catheter intra-arterial infusion of papaverine . Other recent study revealed vasodilator administration from SMA achieved successful treatment in 64% patients of NOMI after open heart surgery with nonsurgical treatment . The strategy and management of NOMI with type B AD involving the SMA have not yet been established, and research is limited . Thus, there are two overwhelming difficulties: risk from the catheterization of the dissected aorta and the accurate and prompt evaluation of NOMI.. First, the catheterization of and arterial infusion for the dissected aorta are essential, and more safety ...

COMPUTATIONAL FLUID DYNAMICS OF TYPE B AORTIC DISSECTION | IRIS Università degli Studi di Palermo
Type B aortic dissection (AoD) is a disease connected to high blood load on the aortic wall and to a reduced aortic wall resistance. Nowadays, prognosis on type B AoD results to be particularly difficult with an high incidence of patients treated with medical therapy which manifest complication connected with dissection and which should have been treated with surgical repair immediately. This work aims to study those haemodynamical and morphological proprieties of dissected aorta, which can influence the progression or stability of type B AoD. Computational fluid-dynamic analyses were performed on twenty-five patients with type B AoD, whose nine presented an aneurysm evolution and sixteen presented no further complication connected with dissection. Blood flow features showed that the true lumen flow was laminar and uniform while false lumen flow was less homogeneous with a consequent recirculating path. We found that entry point zone proximal to the aortic arch showed both high blood velocity ...
Technical eligibility for endovascular treatment of the aortic arch after open type A aortic dissection repair
Objective: To report on the technical eligibility of patients previously treated for Stanford type A aorta dissection (AAD) for endovascular aortic arch repair based on contemporary anatomical criteria for an arch inner-branched stentgraft (AIBS). Methods: All patients treated for AAD from 2004-2015 at a single aortic centre were identified. Extent of repair and use of circulatory arrest were reported. Survival and reoperation were assessed using Kaplan Meier and competing risk models. Anatomic assessment was performed using 3-dimensional CT-imaging software. Primary outcome was survival ≥ 1 year and fulfilment of the AIBS anatomical criteria. Results: A total of 198 patients were included (158 Debakey I, 32 Debakey II, and 8 Intramural hematoma). Mortality was 30-days: 16.2%, 1-year: 19.2%, 10-years: 45.0%. There were 129 patients with imaging beyond 1 year (mean, 47.8 months), while 89 (69.0%) were AIBS eligible. During follow-up, 19 (14.7%) patients met the threshold criteria for aortic ...

A Case of Spontaneous Rupture of the Ascending Aorta
The patient was a 69-year-old man brought to the emergency room with severe chest pain. A contrast chest CT scan revealed a hematoma around the ascending aorta and a notch in the aortic wall, suggesting an intimal tear. An emergency operation was performed via standard median sternotomy under deep hypothermic circulatory arrest. Upon operation, there was a 2.0cm intimal tear just above the right coronary leaflet, which was extended near the right coronary artery orifice. There was no specific evidence of aortic aneurysm or dissection, therefore a spontaneous rupture of the ascending aorta was diagnosed. The pathological finding was cystic medial necrosis Grade 2. His postoperative course was unremarkable and he was discharged 12 days after surgery ...
