Successful endovascular repair with coil embolization of ruptured right internal thoracic artery aneurysm / Reparo endovascular bem-sucedido de aneurisma da artéria torácica interna direita roto com embolização com molas

Abstract Internal thoracic artery aneurysms (ITAAs) are rare with wide variation in clinical presentation and a high risk of rupture. Endovascular techniques are increasingly being used for treatment of such aneurysms over surgical repair in recent times. A 34-year-old male presented with progressive swelling of the right anterior chest wall for 2 weeks and was diagnosed with right internal thoracic artery aneurysm with contained rupture. He underwent successful endovascular repair with coil embolization of ruptured right ITAA. Post intervention computed tomography (CT) angiography confirmed sealing of the ruptured aneurysm with no residual filling of the sac. At six months follow-up he is doing well with complete resolution of hematoma. This case demonstrates that an endovascular approach with coil embolization is a feasible and safe option for treating the rare ruptured ITAAs.

Resumo Os aneurismas da artéria torácica interna (ITAAs) são raros, com ampla variação na apresentação clínica e alto risco de ruptura. As técnicas endovasculares têm sido cada vez mais utilizadas para o tratamento desses aneurismas em relação ao reparo cirúrgico. Um homem de 34 anos de idade apresentou edema progressivo da parede torácica anterior direita por 2 semanas e foi diagnosticado com aneurisma da artéria mamária interna direita com ruptura contida. Ele foi submetido a reparo endovascular bem-sucedido, com embolização de ITAA direito roto. A angiotomografia computadorizada (angioTC) pós-intervenção confirmou o selamento do aneurisma rompido, sem enchimento residual do saco. No seguimento de 6 meses, ele estava bem, com resolução completa do hematoma. Este caso demonstra que a abordagem endovascular com embolização com molas é uma opção viável e segura no tratamento dos raros ITAAs rotos.

Pulmonary artery aneurysm rupture

Pulmonary artery aneurysm is a disorder of varying etiology and should be diagnosed early for appropriate interventions. A 45-year-old man was hospitalized for chest pain, dyspnea, cough, chills, diarrhea, and vomiting, which had started 3 weeks before admission. Physical examination indicated a reduced vesicular murmur in the right hemithorax. A chest x-ray performed indicated a pneumothorax and pulmonary abscess in the right hemithorax. Thoracostomy released abundant purulent and fetid fluid. Direct examination of the pleural fluid using saline revealed structures similar to Trichomonas. Non-contrast chest computed tomography revealed right pneumothorax along with an irregular cavitation located at the pleuropulmonary interface of the posterior margin of the right lower lobe. A pleurostomy was performed. On the second postoperative day, the patient suffered a sudden major hemorrhage through the surgical wound and died on the way to the operating room. The autopsy revealed an abscess and ruptured aneurysm of the lower lobar artery in the lower right lung. Microscopic examination revealed extensive liquefactive necrosis associated with purulent inflammation and the presence of filamentous fungi and spores. This case can be characterized as a severe disorder that requires early diagnosis to achieve a good therapeutic response and to avoid fatal outcomes.

Anterior Communicating Artery Aneurysm Uncommon Hemorrhagic Presentation: Case Report

Intracranial aneurysm rupture causes subarachnoid hemorrhage in 80% of the cases, and it may be associated with intracerebral hemorrhage and/or intraventricular hemorrhage (IVH) in 34% and 17% of the patients, respectively. However, on rare occasions, aneurysm rupturemay be present causing isolate intracerebral hemorrhage or IVH without subarachnoid hemorrhage. We describe an unusual case of an anterior communicating aneurysm rupture presented with IVH, without subarachnoid hemorrhage. Although isolated IVH is rare, aneurysm rupture is a possible condition. Patients presenting with head computed tomography revealing IVH without subarachnoid hemorrhage should be promptly investigated with contrasted image exam to identify and treat possible causes, even in the absence of subarachnoid hemorrhage.

Ruptured renal artery aneurysm in a pregnant woman: case report and literature review / Ruptura de aneurisma de artéria renal em gestante: relato de caso e revisão da literatura

Abstract Renal artery aneurysms (RAAs) are rare and usually asymptomatic; ~ 90% of them are unilateral. Once diagnosed during pregnancy, they may rupture, presenting a high maternal-fetal risk. The present study reports the case of a 32-year-old pregnant woman with a 30-week gestational age and a ruptured unilateral RAA.

Resumo Os aneurismas de artéria renal (AAR) são raros, normalmente assintomáticos, e ~ 90% dos casos são unilaterais. Uma vez diagnosticados durante a gestação, estes podem se tornar predisponentes a rotura e apresentar elevado risco materno-fetal. O presente artigo relata o caso de uma gestante de 32 anos, com idade gestacional de 30 semanas e quadro de AAR unilateral roto.

Procedure-related Complications during Endovascular Treatment of Intracranial Saccular Aneurysms

OBJECTIVE: We evaluate the rates and outcomes of major procedure-related complications during coiling. MATERIALS AND METHODS: Between 2007 and 2015, 436 intracranial saccular aneurysms were treated. Complications are categorized as three types: intraprocedural aneurysm rupture (IAR), thromboembolism (TE), and post-procedural early rebleeding (PER). And we evaluated the risk factors of procedure related complications by multivariate analysis. RESULTS: Complications occurred in 61 aneurysms (14%). The overall incidence of complications in subarachnoid hemorrhage (SAH) was significantly higher than in unruptured intracranial aneurysm (UIA) (20% vs. 6%). The incidence of IAR and TE were higher in SAH than in UIA (IAR 12% vs. 4%, TE 7% vs. 3%, p 0.05). All 7 patients who had IAR during BAC had good recovery. In multiple logistic regression analysis, female gender, SAH, and intraventricular hemorrhage were associated with procedure related complication (p < 0.05). CONCLUSION: Endovascular coil embolization is a minimally invasive procedure, but incidence of its complication is not low, especially in SAH. BAC can be a good tool to avoid poor outcome from unexpected IAR during coiling. While IA tirofiban injection is a useful therapy in TE during coiling, sometimes we are aware of the risk of the early rebleeding in SAH patients.

Related factors and treatment of intraoperative rupture during embolization of intracranial aneurysms / 中国医师进修杂志

Objective To study the causes, emergency managements and preventative measures of intraoperative rupture during embolization of intracranial aneurysms. Methods One hundred and thirty-two patients with intracranial aneurysms and having performed embolization were enrolled. Intraoperative rupture occurred in 6 patients during embolization of intracranial aneurysms. The causes were analyzed and emergency managements were reviewed. Results The causes were as follows: intracranial aneurysms were punctured by microtubular in 2 patients, by spring coil in 1 patient and by guidewire in 1 patient, and intracranial aneurysms were attributed to stent break in 1 patient and blood pressure fluctuation in 1 patient. The rapid embolization were performed, 1 patient underwent craniotomy evacuation of hematoma, 1 patient underwent lateral ventricular drainage, 2 patients underwent lumbar cistern drainage, and 2 patients did not receive any processing. At the discharge from hospital, 2 patients recovered well, 1 patient showed mild paralysis, 1 patient had severe disability, and 2 patients died. Conclusions Intraoperative rupture during embolization of intracranial aneurysms is the life-threatening complication and mainly relates to operation, structure of aneurysm, blood pressure fluctuation during operation. The prognosis depends on the extent of bleeding and appropriate treatment without delay.

Case Report of Rupture of Splenic Artery Aneurysm during Pregnancy with Poor Outcomes.

Aims: To highlight the importance of considering non-obstetrical etiologies for acute abdominal pain in gravid patients with risk factors for vasculopathies including diabetes and hypertension. Specifically, we report a tragic case of splenic artery aneurysm (SAA) rupture during the third trimester in a diabetic patient resulting in maternal-fetal mortality. Traumatic vascular events during pregnancy may be associated with a high rate of maternal and fetal morbidity or mortality. Therefore early and rapid intervention is critical to the obstetrical outcome. Presentation of Case: A 35 year old multiparous hypertensive diabetic patient presented with acute abdominal pain at 33 weeks of gestation. The presumptive diagnosis was concealed placental abruption with diabetic ketoacidosis. Although nonobstetrical diagnoses were not initially considered, postmortem analysis revealed a nonobstetrical etiology of SAA rupture with catastrophic consequences for the patient and fetus. Discussion: The likelihood of aneurysm rupture of SAA is heightened due to vasculopathic medical comorbidities such as hypertension and diabetes. The vascular congestion of pregnancy increases flow through arteries, leading to increased likelihood of aneurysm rupture without warning or preceding symptoms. Preconception screening and imaging modalities to confirm splenic artery aneurysms and elective repair are also discussed. Early consideration and accurate identification of SAA rupture is critical to saving the lives of both mother and fetus. Conclusion: SAA rupture, in the differential diagnosis of acute abdominal pain in pregnancy, should be considered more likely in multiparous patients and in the presence of comorbidities such as diabetes and hypertension.

Repair of ruptured abdominal aortic aneurysms with bifurcated endografts: a single-center study

OBJECTIVE: The aim of this study was to describe our early experience in the treatment of ruptured abdominal aortic aneurysms with bifurcated endografts. We report on our initial twelve-month experience using this approach. METHODS: Clinical data on patients with ruptured abdominal aortic aneurysms treated at a single tertiary center in Brazil were prospectively recorded. The eligibility for endovascular treatment was evaluated by computed tomography scanning and anatomical features were determined based on the method of treatment. RESULTS: From February 2012 to January 2013 (12 months), 28 consecutive patients (mean age 67.2 years, range 45-85 years) underwent treatment for ruptured abdominal aortic aneurysms at our hospital. Eighteen patients (64.3%) were suitable for and underwent endovascular treatment with bifurcated endografts (16 patients) or aortouniiliac endografts (two patients). Ten patients who were considered unsuitable for endograft repair underwent open repair. Seven patients were classified as hemodynamically unstable (Endovascular, 5; Open, 2), and 21 were classified as stable (Endovascular, 13; Open, 8). The overall 30-day mortality rate associated with endovascular treatment was 27.8% (stable, 18.7%; unstable, 40%) and the rate associated with open repair was 50% (stable, 37.5%; unstable, 100%). CONCLUSIONS: In this study, the suitability of patients for endovascular repair of ruptured abdominal aortic aneurysms was high and the overall results of endovascular treatment remain encouraging. Indeed, bifurcated endografts are a feasible option for treating anatomically eligible ruptured abdominal aortic aneurysms. .

Distribution and length of osteophytes in the lumbar vertebrae and risk of rupture of abdominal aortic aneurysms: a study of dry bones from Chiang Mai, Thailand / 대한해부학회지

Vertebral osteophytes are a characteristic feature of intervertebral disc degeneration. In the lumbar spinal region, the two major structures in close proximity anterior to the spine are the inferior vena cava and the abdominal aorta, both of which have been reported to be affected by osteophytes. The purpose of this study was to determine the distribution, classification and lengths of osteophytes in the lumbar vertebrae. One hundred and eighty lumbar columns of 90 males and 90 females from Chiang Mai, Thailand, in the age range 15 to 96 years (mean age, 63 years) were collected. The measuring length of osteophytes was assessed on vertebral body and articular facet. Statistical analysis was performed by descriptive analysis, chi-square and Pearson Correlation. Lumbar osteophytes were presented in 175 specimens (97.2%), 88 males and 87 females. The highest frequency was at L4, most were on the superior, inferior surface of body and articular facet (39.7%, 38.4%, and 22%), respectively. The greatest mean length was 3.47+/-2.21 mm at L5, and the longest length of anterior superior surface of body was 28.56 mm. The osteophyte length was significantly correlated directly with age (P<0.01), and males were significantly greater than females (P<0.05). The highest prevalence of osteophytes was on the anterior side of superior surface of body (30.4%), and the classification was traction. It can be proposed that the abdominal aorta could be damaged, especially a risk of rupture of abdominal aortic aneurysm.

Objective Toinvestigatetheimpactofthedifferentrupturepoints(sac,neck,andtop) of intraoperative aneurysm rupture (IAR)on the prognosis of patients in anterior circulation aneurysm clipping.Methods Theclinicaldataof135consecutivepatients(148aneurysms)acceptedmicrosurgical aneurysm clipping from May 2009 to March 2012 were analyzed retrospectively. The prognostic evaluation of the patients after procedure was assessed by using the Glasgow outcome scale (GOS). The different aneurysm rupture points of IAR were used as influencing factors,and the relationship between the different rupture pointsandtheprognosisofpatientswasanalyzed.Results Duringclippingof148aneurysmsin 135 patients,31 aneurysms in 30 patients had intraoperative rupture (20. 9% of the aneurysms, 22.2% of the patients). Nine rupture points occurred on the top of aneurysms,17 occurred on the sac,and 5 occurred on neck. The Glasgow outcome scale (GOS)scores 5,4,3,2 and 1 were in 17,8,2,1 and 2 patients,respectively. A total of 25 patients had good prognosis and 5 cases had poor prognosis. There were no significant differences in the impact of different rupture points of IAR on the prognosis in patients of IAR (OR,100. 00,95% confidence interval 6. 764-18. 344,P=0. 006). Of the 25 patients with aneurysm sac or top rupture,1 case had poor prognosis. Of the 5 patients with aneurysm neck rupture, 4caseshadpoorprognosis.Conclusion Inanteriorcirculationaneurysmclipping,thedifferent aneurysm rupture points may have significant impact on the prognosis of patients,the aneurysm neck rupture is a main factor for resulting in the poor prognosis of patients.

Objective To explore the diagnosis value of CT in subarachnoid hemorrhage(SAH) induced by aneurysm rupture.Methods The clinical and CT data of 119 patients with SAH induced by aneurysm rupture were analyzed respectively.Results The CT characteristic of SAH induced by aneurysm rupture was full of hyperderse in sulcus and schizenceplay,or accompaning intracerebral hematoma in the straight gyrus of frontal lobe and the hippocampal gyrus of parietal lobe.Conclusion The CT has important value for diagnosing SAH induced by aneurysm rupture in the location and the nature.But it is indispensable that the CTA or DSA must be done for ascertaining the artery of responsibility of rupturing aneurysm.

Spontaneous Thrombosis of a Ruptured Deep Femoral Artery Aneurysm / 日本心臓血管外科学会雑誌

We report a rare case of spontaneous thrombosis of a ruptured deep femoral artery aneurysm. An 85-year-old man presented two days after onset of acute swelling and pain in the left groin. Computed tomography demonstrated rupture of a deep femoral artery aneurysm and thrombosis of the aneurysm. After 1 month of observation, surgical intervention was performed as the local pain persisted. Opening of the aneurysm sac confirmed that thrombosis was complete. Simple ligation and drainage of the aneurysmal sac was performed. His postoperative course was uneventful.

Symptomatic Tarlov Cyst Following Spontaneous Subarachnoid Hemorrhage

Most of Tarlov or perineurial cysts remain asymptomatic throughout the patient's life. The pathogenesis is still unclear. Hemorrhage has been suggested as one of the possible causes and trauma with resultant hemorrhage into subarachnoid space has been suggested as an origin of these cysts. However, Tarlov cysts related to spontaneous subarachnoid hemorrhage has not been reported. The authors report a case of Tarlov cyst which was symptomatic following spontaneous subarachnoid hemorrhage.

Subarachnoid and Intraventricular Hemorrhage due to Ruptured Aneurysm after Combined Spinal-Epidural Anesthesia

A patient received combined spinal-epidural anesthesia for a scheduled total knee arthroplasty. After an injection of spinal anesthetic and ephedrine due to a decrease in blood pressure, the patient developed a severe headache. The patient did not respond to verbal command at the completion of the operation. A brain CT scan revealed massive subarachnoid and intraventricular hemorrhages, and a CT angiogram showed a ruptured aneurysm. Severe headaches should not be overlooked in an uncontrolled hypertensive patient during spinal anesthesia because it may imply an intracranial and intraventricular hemorrhage due to the rupture of a hidden aneurysm.

Aneurisma del seno de Valsalva roto: informe de casos y revisión de la literatura / Sinus of Valsalva aneurysm with rupture: case report and literature review

Introducción: El aneurisma del seno de Valsalva es una dilatación que se origina por adelgazamiento de la unión de la capa media aórtica y el anillo fibroso; de origen adquirido y más frecuentemente congénito. El seno coronario derecho es el más afectado y la rotura es la complicación más común. Casos clínicos: Presentamos dos casos de aneurisma del seno de Valsalva roto a cavidades derechas con insuficiencia cardiaca severa, que constituyeron 0.4 % del total de cirugías cardiacas realizadas en un año en el Hospital de Especialidades, Centro Médico Nacional de Occidente, Guajalajara, Jalisco. Caso 1: hombre de 27 años con disnea de pequeños esfuerzos, disnea paroxística nocturna, ortopnea, fibrilación auricular paroxística, soplo diastólico, hepatomegalia y edema de miembros inferiores. Caso 2: hombre de 33 años con disnea de pequeños esfuerzos, disnea paroxística nocturna, ortopnea, soplo diastólico, insuficiencia renal aguda e insuficiencia hepática congestiva. La resolución quirúrgica consistió en resección del aneurisma y cierre del defecto con parche de dacrón, preservando la válvula aórtica. Ambos casos sobrevivieron. Conclusiones: La presencia de insuficiencia cardiaca y cambios auscultatorios súbitos obligan a sospechar aneurisma del seno de Valsalva roto. La ecocardiografía es suficiente para diagnosticar aneurisma del seno de Valsalva, sus complicaciones, repercusión y orientación quirúrgica. Cuando es asintomático existe riesgo de expansión, rotura, insuficiencia cardiaca, endocarditis, embolia y muerte súbita, lo que justifica la resolución quirúrgica, la cual tiene baja mortalidad a corto y largo plazo.

BACKGROUND: The sinus of Valsalva aneurysm (SVA) is a small dilatation caused by a separation between the aortic media and annulus fibrosus. Its origin may be either acquired or congenital. The right coronary sinus is most frequently affected, with the most common complication being rupture. CLINICAL CASES: We report two cases of SVA complicated with rupture to the right cavities with severe cardiac failure, which represents 0.4% of the total cardiac surgeries performed during the past year in our hospital. Case #1: We present the case of a 27-year-old male with low-effort dyspnea, nocturnal paroxysmal dyspnea, orthopnea, paroxysmal atrial fibrillation, diastolic murmur, hepatomegaly and edema of the lower extremities. Case #2: We present the case of a 33-year-old male with low-effort dyspnea, nocturnal paroxysmal dyspnea, orthopnea, diastolic murmur, severe kidney insufficiency and congestive hepatic insufficiency. Surgical resolution in both cases consisted of aneurysm resection and closure of the defect with a Dacron patch, preserving the aortic valve. Both patients survived. CONCLUSIONS: Cardiac failure and sudden auscultation changes suggest the possibility of SVA rupture. Echocardiography is sufficient to diagnose SVA, its complications, repercussions, and surgical options. SVA, even if asymptomatic, has potential risks of expansion, rupture, cardiac failure, endocarditis, embolism and sudden death. This justifies surgical correction, with a low mortality rate in both the short- and long-term.

Significance of Aspect Ratio as Predictor of Intracranial Aneurysm Rupture / 대한뇌혈관외과학회지

OBJECTIVE: The size of intracranial aneurysm has been well known as a risk factor of aneurysmal rupture. The aneurysmal shape affects risk of rupture differently even though the size is similar. Aspect ratio corresponds well with morphologic variability. In this study we investigated the significance of aspect ratio as a predictor of intracranial aneurysm rupture. METHODS: The authors reviewed the retrospectively the medical records of consecutive patients with ruptured and unruptured intracranial aneurysms who underwent cerebral angiography from January 2001 to December 2005. A total of 156 patients underwent cerebral angiography and 171 aneurysms were detected. One hundred forty ruptured and 31 unruptured aneurysms were included. We measured aspect ratio which aneurysmal dome distance and neck width on angiographic images. To compare the difference of size and aspect ratio between ruptured and unrupteured aneurysms, we performed statistical analysis of aspect ratio to obtain the odds ratio(OR) for risk of rupture. RESULTS: The mean aspect ratio was 2.33+/-0.96 for ruptured aneurysms, compared with 1.71+/-0.55 for unruptured aneurysms. The difference of the aspect ratios between ruptured and unruptured groups was statistically significant (p<0.001). The odds ratio of rupture was 6.3 fold greater when the aspect ratio was larger than 2.66 compared with an aspect ratio less than 1.54. CONCLUSION: We suggest that aspect ratio is a significant independent predictor for aneurysmal rupture. The rupture risk was increased significantly when aspect ratio increased.

Rupture of Popliteal Arterial Aneurysm due to Salmonella Infection

We report here on a case of popliteal aneurysm and rupture that occurred over a 10-day period and this was all secondary to salmonella infection. Computed tomography (CT) angiography of the extremity that was performed before and after aneurysmal rupture showed the aneurysm's rapid evolution to rupture over a short period of time. We also review the pathogenesis, clinical presentation, diagnostic approach and management of salmonella aneurysms.
