ABSTRACT

Ultrasound-measured inferior vena cava (IVC) and abdominal aorta (Ao)-associated parameters have been used to predict volume status for decades, yet research focusing on the impact of individual physical characteristics, including gender, height/weight, body surface area (BSA), and age, assessed simultaneously on those parameters in Chinese children is lacking. The aim of the present study was to explore the impact of individual characteristics on maximum IVC diameter (IVCmax), Ao, and IVCmax/Ao in healthy Chinese children. From September to December 2015, 200 healthy children from 1 to 13 years of age were enrolled. IVCmax and Ao diameters were measured by 2D ultrasound. We found that age (years), height (cm), weight (kg), waist circumference (cm), and BSA (m2) were positively correlated with IVCmax and Ao. Multivariate linear regression showed that age was the only independent variable for IVCmax (mm) in female children, height was the only independent variable for IVCmax in male children, and age was the only independent variable for Ao in both females and males. IVCmax/Ao was not significantly influenced by the subjects' characteristics. In conclusion, IVCmax and Ao were more susceptible to subjects' characteristics than IVCmax/Ao. IVCmax/Ao could be a reliable and practical parameter in Chinese children as it was independent of age, height, and weight.

ABSTRACT

A síndrome de quebra-nozes é caracterizada por um grupo de manifestações clínicas que ocorrem por conta da compressão da veia renal esquerda. Seus principais sintomas são macro e micro-hematúria, proteinúria e dor no flanco. O diagnóstico é geralmente realizado após a exclusão de outras causas mais comuns, por conta da ausência de critérios clínicos para diagnóstico. Sua confirmação é feita por exames de imagem, com uso da ultrassonografia Doppler e tomografia computadorizada. O tratamento pode variar com as características do paciente e com a gravidade dos sintomas, e inclui o tratamento conservador, a cirurgia aberta e a cirurgia endovascular. Atualmente, a cirurgia aberta continua sendo a linha de frente, mas abordagens menos invasivas vêm ganhando cada vez mais espaço


The nutcracker syndrome is characterized by a group of clinical manifestations caused by compression of the Left Renal Vein. The main symptoms are: macro and micro hematuria, proteinuria, and flank pain. Diagnosis is usually made after excluding other causes, because there are no clinical criteria for diagnosis. Confirmation is by Doppler ultrasonography or computed tomography. Treatment can vary, depending on patient characteristics and the severity of the symptoms, while conservative treatment, open surgery, and endovascular surgery may be employed. Currently, open surgery is still the first-line treatment, but some less invasive approaches are gaining acceptance

ABSTRACT

The aim of this study was to determine the vascular indices of adrenal blood flow in healthy dogs (systolic velocity - SV; diastolic velocity - DV; resistance index - RI). Eighteen dogs (thirty six adrenal) were studied. Physical examination, biochemical profile and dexamethasone suppression test were performed to determine general health status. Echotexture, size, contours and margins, and overall shape of the adrenal gland (right and left) were assessed via ultrasound. By spectral Doppler of the phrenic-abdominal artery, the SV, DV, and RI were acquired. Animals did not show alterations in clinical and laboratory examination and suppression of cortisol. Normal homogeneous and echotexture, regular contours and margins and normal shape and size were verified via B mode. Spectral Doppler of the phrenic-abdominal artery showed monophasic-patterned waves and low vascular resistance and systolic peak evident with means values: left adrenal - SV = 31.34cm/s, DV = 9.54cm/s and RI = 0.69; and right adrenal - SV = 27.83cm/s, DV = 7.71cm/s and RI = 0.68. Doppler evaluation of adrenal was easily implemented and may provide base line data in the study, allowing for the use of this technique as a diagnostic tool for diseases of the dog's adrenal.(AU)


Objetivou-se determinar os índices vasculares do fluxo sanguíneo das glândulas adrenais de cães saudáveis (velocidade sistólica - VS; velocidade diastólica - VD; o índice de resistência - IR). Foram utilizados neste estudo 18 cães (36 adrenais). Foram realizados exame físico, perfil bioquímico e teste de supressão com dexametasona para determinar o estado geral de saúde (higidez). Ecotextura, ecogenicidade, tamanho, contornos e margens e o formato das glândulas adrenais (direito e esquerdo) foram avaliados por meio da ultrassonografia convencional. Ao Doppler espectral da artéria frênico-abdominal, foram adquiridos a VS, a VD e o IR. Os animais não apresentaram alterações aos exames clínico, laboratorial e de supressão do cortisol. Ao exame ultrassonográfico, foram verificados ecotextura homogênea, ecogenicidade, formato e tamanhos normais, além de os contornos e as margens serem regulares. Ao Doppler espectral da artéria frênico-abdominal, verificaram-se ondas com padrão monofásico, com resistência vascular baixa e pico sistólico evidente, sendo os valores médios: adrenal esquerda - VS = 31,34cm/s, VD = 9,54cm/s e IR = 0,69; e adrenal direita - VS = 27,83cm/s, VD = 7,71cm/s e IR = 0,68. A avaliação Doppler das adrenais foi facilmente implementada e pode fornecer dados de referência, permitindo a utilização dessa técnica como uma ferramenta de diagnóstico para doenças das adrenais em cães.(AU)

ABSTRACT

OBJECTIVES: This study aimed to evaluate the role of multidetector computed tomography angiography in diagnosing patients with pulmonary sequestration. METHODS: We retrospectively analyzed the computed tomography studies and clinical materials of 43 patients who had undergone preoperative multidetector computed tomography angiography in our hospital and had pathologically proven pulmonary sequestration. Each examination of pulmonary sequestration was reviewed for type, location, parenchymal changes, arterial supply and venous drainage on two-dimensional and three-dimensional computed tomography images. RESULTS: Multidetector computed tomography successfully detected all pulmonary sequestrations in the 43 patients (100%). This included 40 patients (93.0%) with intralobar sequestration and 3 patients (7.0%) with extralobar sequestration. The locations of pulmonary sequestration were left lower lobe (28 cases, 70% of intralobar sequestrations), right lower lobe (12 cases, 30% of intralobar sequestrations) and costodiaphragmatic sulcus (3 cases). Cases of sequestered lung presented as mass lesions (37.2%), cystic lesions (32.6%), pneumonic lesions (16.3%), cavitary lesions (9.3%) and bronchiectasis (4.6%). The angioarchitecture of pulmonary sequestration, including feeding arteries from the thoracic aorta (86.1%), celiac truck (9.3%), abdominal aorta (2.3%) and left gastric artery (2.3%) and venous drainage into inferior pulmonary veins (86.0%) and the azygos vein system (14.0%), was visualized on multidetector computed tomography. Finally, the multidetector computed tomography angiography results of the sequestered lungs and angioarchitectures were surgically confirmed in all the patients. CONCLUSIONS: As a noninvasive modality, multidetector computed tomography angiography is helpful for making diagnostic decisions regarding pulmonary sequestration with high confidence and for visualizing the related parenchymal characteristics, arterial supply, and venous drainage features to help plan surgical strategies.

ABSTRACT

Vascular structures are in greater danger during lumbar surgery. The purpose of this study is to describe the morphology of the inferior vena cava (IVC) related to the lumbar vertebra and aortic bifurcation (AB) and assessing the role of demographic values in these relations to decrease the risk of complications in the surgical interventions. The study was performed on Multidetector Computed Tomography (MDCT) images of 100 male and 100 female cases with an age range from 50 to 84 years. The morphometric values of the IVC obtained from the coronal, sagittal and the axial reformatted images were measured and compared with the demographic values. The distance from the IVC to the 1st lumbar vertebra (L1) and 2nd lumbar vertebra (L2) were measured as (26.5 mm and 18.1 mm) in males and (21.1 mm and 14.2 mm) in females with a high level of significance between genders; the distance from the IVC to the iliocaval confluence (IC), 3rd lumbar vertebra (L3) and 4rd lumbar vertebra (L4) were measured as (6.5 mm, 10.5 mm and 6.9 mm) in males and (4.9 mm, 9.1 mm and 5.5 mm) in females with significance between genders. The level of the IC was detected 46 % of males, 39 % of females at the level of lower third of L4. The vertical distance between the IC and the AB was measured and negative correlation between genders based on age was detected. Demographic values are important to consider the relationship of the IVC, the lumbar vertebra and the AB. The IVC was located further from the lumbar vertebra in males compared to females. Age increase played role in the approaching of the AB and the IC to each other in both gender and the IC to the promontory level in males.


Las estructuras vasculares corren gran peligro durante la cirugía lumbar. El propósito de este estudio fue describir la morfología de la vena cava inferior (VCI) en relación con las vértebras lumbares y la bifurcación aórtica (BA), junto con evaluar los valores demográficos de estas relaciones para disminuir el riesgo de complicaciones en las intervenciones quirúrgicas. Se utilizaron tomografías computadorizadas multidetector (TCMD) de 100 casos de hombres y mujeres entre 50 a 84 años de edad. Los valores morfométricos de la VCI se obtuvieron desde imágenes coronales y sagitales reformateadas, medidas y comparadas con los valores demográficos. Se midió la distancia de la VCI a la 1a (L1) y 2a vértebra lumbar (L2), en hombres de 26,5 mm y 18,1 mm respectivamente, y en mujeres de 21,1 mm y 14,2 mm, respectivamente, con un alto nivel de significancia entre el sexos. La distancia desde la VCI a la confluencia iliocava (CI), 3a (L3) y 4a vértebra lumbar (L4) fue para los hombres de 6,5 mm, 10,5 mm y 6,9 mm, respectivamente, y en mujeres de 4,9 mm, 9,1 mm y 5,5 mm respectivamente, con significancia entre los sexos. El nivel de la IC se detectó en 46 % de los varones y en el 39 % de las mujeres, a nivel de tercio inferior de L4. La distancia vertical entre la CI y la BA se tuvo una correlación negativa entre sexos en base a la edad. Los valores demográficos son importantes al considerar la relación de la VCI, las vértebras lumbares y la BA. La VCI se encuentra a una distancia mayor de las vértebras lumbares en hombres que en mujeres. El incremento de la edad jugó un papel importante en la aproximación de la BA y la IC, tanto entre sí como según sexo, con la CI a nivel del promontorio en los hombres.

ABSTRACT

ABSTRACT A 59 year-old patient was admitted with upper gastrointestinal bleeding. The clinical exam showed mild hypotension and blood samples revealed acute anemia (hemoglobin = 7.5 g/dl). Emergency computed tomography showed an infrarenal abdominal aortic aneurysm and extravasation of the arterial contrast material toward the digestive tract. The patient was transported to the operating room for emergency laparotomy, which showed an aortoduodenal fistula. After proximal and distal aortic vascular control, the two anatomical structures were dissected with duodenorrhaphy, patch repair of the aortic tear and omentum interposition. The postoperative recovery was uneventful, with discharge after 12 days.

ABSTRACT

PURPOSE: Coronary artery disease (CAD) shares several risk factors with abdominal aortic aneurysm (AAA). We evaluated the prevalence during transthoracic echocardiography (TTE) and risk factors of AAA in patients with CAD. MATERIALS AND METHODS: A total of 1300 CAD patients were screened from August 2009 to May 2010, and measurement of abdominal aorta size was feasible in 920 patients (71%) at the end of routine TTE. An AAA was defined as having a maximal diameter of > or =30 mm. RESULTS: Of the 920 patients, 22 (2.4% of the study population) were diagnosed with AAA; of these AAA patients, 86% were male, and 82% were over 65 years-old. Abdominal aortic size was weakly correlated with aortic root diameter (r=0.22, p<0.01). Although the proportions of male gender, hypertension, and dyslipidemia were higher in AAA patients, such differences were not statistically significant. Advanced age [odds ratio (OR)=1.07; 95% confidence interval (CI): 1.01-1.12; p<0.01], smoking (OR=3.44; 95% CI: 1.18-10.04; p=0.02), and peripheral arterial disease (OR=5.88; 95% CI: 1.38-25.05; p=0.01) were found to be associated with AAA. CONCLUSION: Although prevalence of AAA is very low in the Asian population, the prevalence of AAA in Asian CAD patients is higher than the general population. Therefore, opportunistic examination of the abdominal aorta during routine TTE could be effective, especially for male CAD patients over 65 years with a history of smoking or peripheral arterial disease.

ABSTRACT

Primary aortoenteric fistula (PAEF) is a rare but catastrophic cause of massive gastrointestinal bleeding. Diagnosis of PAEF is difficult to make and is frequently delayed without strong clinical suspicion. Timely surgical intervention is essential for patient's survival. We report on a case of an 86-year-old woman with no history of abdominal surgery, who presented with abdominal pain. Initially, computed tomography scan showed an intra-abdominal abscess, located anterior to the aortic bifurcation. However, she was discharged without treatment because of spontaneous improvement on a follow-up computed tomography scan, which showed a newly developed right common iliac artery aneurysm. One week later, she was readmitted due to recurrent abdominal pain. On the second day of admission, sudden onset of gastrointestinal bleeding occurred for the first time. After several endoscopic examinations, an aortoenteric fistula bleeding site was found in the sigmoid colon, and aortography showed progression of a right common iliac artery aneurysm. We finally concluded that intra-abdominal abscess induced an infected aortic aneurysm and enteric fistula to the sigmoid colon. This case demonstrated an extremely rare type of PAEF to the sigmoid colon caused by an infected abdominal aortic aneurysm, which has rarely been reported.

ABSTRACT

Massive thoracoabdominal aortic thrombosis is a rare finding in patients with iatrogenic Cushing syndrome in the absence of any coagulation abnormality. It frequently represents an urgent surgical situation. We report the case of an 82-year-old woman with massive aortic thrombosis secondary to iatrogenic Cushing syndrome. A follow-up computed tomography scan showed a decreased amount of thrombus in the aorta after anticoagulation therapy alone.

ABSTRACT

Fenestrated endovascular repair of an abdominal aortic aneurysm has been developed to treat patients with a short or complicated aneurysm neck. Fenestration involves creating an opening in the graft fabric to accommodate the orifice of the vessel that is targeted for preservation. Fixation of the fenestration to the renal arteries and the other visceral arteries can be done by implanting bare or covered stents across the graft-artery ostia interfaces so that a portion of the stent protrudes into the aortic lumen. Accurate alignment of the targeted vessels in a longitudinal aspect is hard to achieve during stent deployment because rotation of the stent graft may take place during delivery from the sheath. Understanding the 3D relationship of the aortic branches and the fenestrated vessel stents following fenestration will aid endovascular specialists to evaluate how the stent graft is situated within the aorta after placement of fenestrations. The aim of this article is to provide the 2D and 3D imaging appearances of the fenestrated endovascular grafts that were implanted in a group of patients with abdominal aortic aneurysms, based on the multislice CT angiography. The potential applications of each visualization technique were explored and compared with the 2D axial images.

ABSTRACT

The intraaortic balloon pulsation (IABP) catheter is commonly used to treat left ventricular failure. The abnormality of the descending thoracic and abdominal aorta is considered as a relative contraindication for its insertion. We present here a patient with acute myocardial infarction with a post-infarct ventricular septal defect who presented with left ventricular failure. During coronary angiography, tortuous abdominal aorta was noted and IABP catheter was inserted under fluoroscopic guidance to support the cardiovascular system. This case is reported to encourage discussion on the use of IABP catheters in patients with tortuous aorta and avoidance of events described.

ABSTRACT

A 17-yr-old young woman was referred to our hospital with a 2-yr history of claudication of the lower extremities and severe arterial hypertension. Physical examination revealed significantly different blood pressures between both arms (160/92 and 180/95 mmHg) and legs (92/61 and 82/57 mmHg). The hematological and biochemical values were within their normal ranges, except for the increased erythrocyte sedimentation rate (83 mm/hr) and C-reactive protein (6.19 mg/L). On 3- dimensional computed tomographic angiography, the ascending aorta, the aortic arch and its branches, and the thoracic and, descending aorta, but not the renal artery, were shown to be stenotic. The diagnosis of type IIb Takayasu's arteritis was made according to the new angiographic classification of Takayasu's arteritis, Takyasu conference 1994. Percutaneous transluminal angioplasty with stenting was performed on the thoracic and abdominal aorta. After the interventional procedures, the upper extremity blood pressure improved from 162/101 mmHg to 132/85 mmHg, respectively. She has been free of claudication and there have been no cardiac events during 2-yr of clinical follow-up.

ABSTRACT

A 23-year-old female patient with type III nonspecific aortoarteritis (Takayasu's arteritis) presented with multiple obstructive lesions and severe congestive heart failure. Large, cutting balloons 5-8 mm in diameter were used to dilate lesions in the abdominal aorta, both renal arteries, right common carotid artery, proximal left subclavian artery, and ostium of the left vertebral artery. Wide luminal expansion without residual stenosis, substantial dissection or need for adjunctive stenting was achieved at all six angioplasty sites. The use of cutting balloons appears suitable for treating obstructive lesions in aortoarteritis.

ABSTRACT

Radiographic study of geometric anatomy of the aortic-common iliac bifurcation in 27 Nigerian male cadavers revealed a mean length of 5.1 cm for right common iliac artery and 5.4 cm for left common iliac artery. The take off angle of the left common iliac [mean 27.2 degrees] is more than that of the fight common iliac artery, [mean 25.2 degrees]. The mean of radius of curvature is greater on the left [3.6 cm] than the right [2.9 cm]. There is a positive correlation [r.= + 0.53] between the length of the left common iliac artery and the radius of curvature of the right common iliac artery whereas negative correlation [r = 0.95] between its length and take off angle and negative correlation [r = -0.64] between length of the right common iliac artery and take off angle of the left common iliac artery. Studies of the geometric radiographic anatomy of the aortic-common iliac bifurcation can be utilized to see whether a person is prone to occlusive vascular disease of the lower extremity even if no lesion is present at the time of investigation
