RESUMO

We report a complex reconstruction of arteriovenous fistula (AVF). Proximal stenosis of cephalic vein was followed by aneurysms of fistulous veins (distal segment of cephalic vein and median cubital vein) complicated by AVF thrombosis. Blood outflow from AVF was retrograde. One week after thrombosis, an aneurysm of median cubital vein containing dense clots was excised. We resected cephalic vein wall and repaired the vessel. Anastomosis with the brachial artery was created distal to the last anastomosis. Proximal cephalic vein repair was performed using resected aneurysm walls. After a year, AVF has been successfully used for hemodialysis.

RESUMO

PURPOSE: To evaluate the efficacy of endovascular repair of popliteal artery aneurysms (PAAs) with a wire-interwoven nitinol stent. MATERIALS AND METHODS: This is a prospective, descriptive, and analytical study. From January 2016 to December 2018, 28 consecutive patients (29 lower limbs) were treated for a PAA with the deployment of the Supera stent (Abbott Vascular, Illinois). Twenty-three (79.3%) PAAs were asymptomatic; 6 (20.7%) presented with symptoms. The mean diameter and length of the aneurysm were 26.8 mm (20-40 mm) and 47.1 mm (23-145 mm) respectively. The primary endpoint was the prevention of embolic symptoms. The secondary endpoints were aneurysm exclusion, aneurysm diameter decrease, freedom from reintervention, and preservation of preoperative runoff vessels. RESULTS: Technical success was 100%, with a median of 2.4 run-off vessels at completion angiography, without any loss of run-off vessels. A double Supera stent was deployed in 10 cases. At completion angiography, a median of 2.4 runoff vessels were present, without any loss of runoff vessels. The mean follow-up time was 24.3 (12-35) months. Primary endpoints were reached in 100% of the cases and vessels run off was preserved in all cases. In 2 PAAs, complete sac thrombosis was witnessed at 6-month follow-up, while at 12-month follow-up, it was seen in 10 of 29 (34.4%) limbs. In all the other cases the diameter of the aneurysm remained stable, with a freedom from sac enlargement of 100%. No fractures or stent thromboses were detected. CONCLUSIONS: For endovascular repair of PAAs, the use of a thick interwoven-wire stent, that could work like a multilayer flow modulator showed encouraging mid-term results with no cases of stent fracture, occlusion or aneurysm increase.

RESUMO

A 25-year-old Indian man presented with low-grade fever followed by gradually increasing swelling of neck and face. Physical examination showed bilateral neck swelling, facial swelling and dilated veins in the upper chest. Superior vena cava (SVC) obstruction due to an underlying malignancy was suspected. CT thorax showed large saccular aneurysm with thrombosis of bilateral subclavian arteries of which the right one caused external compression of right innominate vein draining into the SVC. A history of recurrent oral and scrotal ulcers was obtained following which skin pathergy test was done, which was suggestive of a diagnosis of Behcet's disease (BD). He responded to treatment with steroids and azathioprine. This report illustrates that rare nonmalignant cause such as BD could also present with SVC obstruction.

RESUMO

Introduction: Congenital renal arteriovenous fistula is an abnormal connection between the arterial and venous system. Since the first case described in 1928 by Varela et al, no more than 200 cases have been published. Material and methods: A 45-year-old woman consulted for severe abdominal and low-back pain associated with arterial hypertension. The CT scan showed an infrarenal retroperitoneal lesion with invasion of neighboring structures. Results: During the abdominal exploration, a vascular-looking lesion of 60 x 34 x 41 mm was identified. It was associated with right nephrectomy. Discussion: The etiology of congenital fistulas remains unknown; it is believed that a congenital arterial aneurysm erodes into an adjacent vein and gradually increases its size. Other authors believe that the fistula exists since birth and gradually increases its size until it causes symptoms. Conclusion: Congenital arteriovenous fistulas are rare entities, representing less than 25% of all renal arteriovenous malformations.

RESUMO

La dilatación idiopática de la aurícula derecha es una entidad poco frecuente. Estimar la verdadera incidencia es dificultoso dado que muchos pacientes son asintomáticos y los síntomas reportados, tanto en niños como en adultos, presentan un amplio espectro de manifestaciones clínicas. Pocos pacientes con diagnóstico prenatal fueron publicados.Se presenta un caso de diagnóstico prenatal de dilatación auricular derecha con un seguimiento de 3 años y 8 meses. El paciente se encuentra asintomático, sin evidencia de trombosis auricular, medicado con ácido acetilsalicílico desde su nacimiento. El seguimiento se realizó con ecocardiogramas regulares; sin embargo, la confirmación diagnóstica fue a través de la resonancia magnética nuclear cardíaca.La importancia del reporte radica en describir una enfermedad rara, potencialmente grave, y cómo el diagnóstico prenatal permite tomar conductas anticipadas, como el monitoreo cardíaco, para la detección de arritmias y el inicio temprano de profilaxis primaria antitrombótic


Idiopathic dilatation of the right atrium is a rare condition. The real incidence of the disease is difficult to estimate since most patients are asymptomatic, although a wide spectrum of symptoms have been reported in children and adults. In the literature, prenatal diagnosis has been reported in few cases.We report a case of prenatally diagnosed right atrial dilation with a 3 years and 8 months follow up. The patient is on acetylsalicylic acid since birth and remained asymptomatic without any atrial thrombosis. We performed regular transthoracic echocardiograms during follow up, however was a cardiac magnetic resonance imaging the method for achieving diagnostic confirmation.The aim of this case report is to describe a rare, potentially serious disease and how prenatal diagnosis allows anticipated actions such as monitoring for cardiac arrhythmia detection and early starting of primary thrombosis prophylaxis.

RESUMO

Renal artery aneurysm is defined as the dilated segment of renal artery exceeding twice the diameter of the normal renal artery. As more than half of such aneurysms have the annular calcification, they must be differentiated from the stones. Differential diagnosis of the renal artery aneurysm includes the parapelvical cysts, hydronephrosis and kidney tumors. Renal artery aneurysm can be diagnosed by CT, MRI, as well by ultrasonography and color dopplerography. Unfortunately presence of calcification renders the ultrasonographic examination impossible. In this article we share our own experience of two cases of calcified renal aneurysms diagnosed and treated at our hospital.

RESUMO

INTRODUÇÃO: O aneurisma de VE (ANEUVE) é uma complicação pós IAM e da doença de Chagas. É causa de arritmias, ICC e tromboembolismo. O CDI está indicado para prevenção da morte súbita arrítmica na ausência de causas removíveis. O ANEUVE pode ser ressecado cirurgicamente e, quando, aplica-se outras abordagens (endoaneurismorrafia, reconstrução do VE, revascularização miocárdica e ablação do foco arritmogênico) pode abolir o circuito da arritmia, melhorar a função ventricular e com isso o prognóstico dos pacientes (P). Objetivo: Apresentar a experiência da fase hospitalar da aneurismectomia de VE com TV instável. Métodos: Revisaram-se os prontuários de 14 P com ANEUVE e TVS hemodinamicamente instável (10P com ICo, 4P DCh; média de idade 60±5,6a, variando entre 52 e 70 a; média da FEVE 35±10%). Após a aneurismotomia, procedeu-se a indução da TV com estimulação ventricular programada (EVP) seguida de mapeamento endocárdico. Após a localização da área alvo realizou-se a ablação com cateter com RF (Cardioablate®). Nova EVP era realizada e, em caso de não indução da TV a cirurgia era complementada com a endoaneurismorrafia e reconstrução do VE com retalho de pericárdio. A revascularização miocárdica era a etapa final caso indicada. Antes da alta hospitalar, os P eram submetidos à EVP. Sendo negativa recebiam alta, em tratamento clínico, em caso positivo submetiam-se ao implante do CDI. Resultados: O ANEUVE localizou-se predominantemente na região anterior. A trombose ventricular foi observada em 3/14P (21%). A TV foi induzida e ablacionada com RF em 14/14 casos (100%). Em apenas 1P (7%) a TV foi reinduzida após a aneurismectomia. Houve tendência de melhora da FE no PO em 12/14P (35±9,8 vs. 39±7,7%; p=0,156). Em 13/14P (93%) a TV não mais foi induzida. Um P (7%) morreu por choque séptico, ainda internado. Um P implantou CDI devido a reindução de TV. Os outros P receberam alta estáveis. Conclusões: a) a aneurismectomia com abordagens para TVS é conduta eficaz em P com risco de MS; b) a comprovação do sucesso terapêutico pode ser demonstrada ainda na cirurgia e confirmada antes da alta com a EVP; c) a conduta utilizada evitou o implante de CDI na maioria dos casos.

RESUMO

INTRODUCTION: The indications for popliteal artery aneurysm treatment are clear. In aneurysms with patent inflow and outflow arteries, the risk of peripheral embolisation from a mural thrombus is high and the treatment, mostly a vascular intervention, is focused on preventing this extremity-threatening complication. It is unclear, however, how high the risk of peripheral embolisation is and how to proceed with a patent popliteal artery aneurysm fed by the deep femoral artery when the superficial femoral artery is chronically occluded. METHODS: All patients diagnosed with popliteal artery aneurysm between 2015 and 2019 were searched in the database of the Department of Surgery II of University Hospital Olomouc. Patients with a patent popliteal artery aneurysm and chronic superficial femoral artery occlusion in the ipsilateral extremity were selected. RESULTS: We diagnosed 66 patients with 85 popliteal artery aneurysms. Four patients had a patent popliteal artery aneurysm and chronic superficial femoral artery occlusion in the ipsilateral extremity. In these patients, conservative treatment was indicated after the diagnosis was determined. In three patients, no clinically obvious complication of the popliteal artery aneurysm occurred. In one patient, popliteal artery aneurysm thrombosis occurred after a follow-up of 21 months, leading to a shortening of his calf claudication distance and limiting the patient. CONCLUSION: Our experience with this small group of patients shows the possibility of primary conservative treatment in patients with a patent popliteal artery aneurysm below the chronic superficial femoral artery occlusion site. Aneurysm thrombosis can be expected during follow-up. Patients in whom the thrombosis leads to limitations are indicated for surgical intervention. The risk of peripheral embolisation from the mural thrombus cannot be excluded with certainty. Further studies involving large groups of patients are needed to provide a more precise recommendation.

RESUMO

The article deals with the relevant literature data concerning diagnosis and treatment of subclavian artery aneurysms. This nosological entity is relatively uncommon, however its importance for modern medicine should not be underestimated. Despite a low incidence of the pathology, it should be understood that the disease's course for the patient is associated with the development of severe complications which may lead to disability or even death. The development of complications is extremely difficult to predict and stratification of risks for such patients is too complicated. It is also known that the diagnosis of a subclavian artery aneurysm is frequently an accidental finding, since the pathology may for a long time proceed symptom-free. At the same time, the subclavian artery occupies the first place by the frequency of localization of upper-limb aneurysms, thus making this problem currently important. Besides, separate attention should be paid to modern methods of correction of this disease, since implementation of high-tech interventions into vascular surgery have significantly expanded the arsenal of the operating surgeon.

RESUMO

Splenic artery aneurysms are rare. Giant aneurysms more than 2,5cm are extremely rare. The splenic artery is the third site after the aorta and iliac arteries, and the first location for aneurysmal lesion of the visceral arteries. The etiology of splenic artery aneurysms is not yet well established, however, fibromuscular dysplasia, non-cirrhotic portal hypertension and pregnancy seem to contribute to the emergence and evolution of arterial lesions. The majority of splenic artery aneurysms are asymptomatic. However, epigastric or left hypochondrial pain may occur. Doppler ultrasound, computed tomography angiography or magnetic resonance imaging are usually performed in the diagnostic workup. Treatment procedure, surgical or endovascular, depends on the aneurysmal site (proximal or distal) and the type of elective or urgent intervention. The present study reports six cases of splenic artery aneurysm, with a diameter greater than 50mm, treated successfully with surgery.

RESUMO

Aneurysmal transformation of arteriovenous fistula (AVF) is a common complication and associated with increased risk of arrosive bleeding. Ligation of fistulous vein is conventional surgery for bleeding. This is followed by AVF malfunction and need for implantation of central venous catheter. We report reconstructive surgery and maintaining the function of AVF in a patient with aneurysmal transformation of AVF after arrosive bleeding. Reconstructive vascular surgery can significantly extend the period of patent AVF for hemodialysis. This is extremely important in patients with reduced resources of native vessels suitable for AVF formation. The same is true if conversion of the type of renal replacement therapy is associated with significant difficulties.

RESUMO

We report the case of a 67-year-old man presenting with abdominal pain due to acute thrombosis of an aneurysm of the superior mesenteric vein. It was treated conservatively by a combination of anticoagulation and monitoring by serial imaging after multidisciplinary discussion. With more than one year of follow-up, no aneurysm growth was observed. Mesenteric vein aneurysm is a rare vascular dilatation, which was first described in 1982 and since then 17 cases have been reported. There are congenital and acquired hypotheses regarding their etiology. If asymptomatic, conservative management is recommended. Monitoring is important because of potential complications (thrombosis, portal hypertension, adjacent organs compression and rupture of aneurysm), which may mandate surgical management.

RESUMO

Endovascular aneurysm repair (EVAR) and thoracic endovascular aortic repair (TEVAR) are effective and minimally invasive treatment options for high-risk surgical candidates. Nevertheless, knowledge about the management of aortic stent graft therapy in chronic kidney disease (CKD) is scarce. This study aimed to examine outcomes after EVAR and TEVAR in patients with CKD.Utilizing data from the Taiwan National Health Insurance Research Database, we retrospectively assessed patients who underwent EVAR and TEVAR therapy between January 1, 2006, and December 31, 2013. Patients were divided into CKD and non-CKD groups. Outcomes were in-hospital mortality, all-cause mortality, readmission, heart failure, and major adverse cardiac and cerebrovascular events.There were 1019 patients in either group after matching. The CKD group had a higher in-hospital mortality rate than the non-CKD group (15.2% vs 8.3%, respectively; odds ratio, 1.92; 95% confidence interval [CI], 1.46-2.54). Patients with CKD had higher risks of all-cause mortality including in-hospital death (46.1% vs 33.1%; hazard ratio [HR], 1.61; 95% CI, 1.35-1.92), readmission rate (62.6% vs 55.0%; subdistribution HR [SHR], 1.61; 95% CI, 1.32-1.69), redo stent (7.8% vs 6.2%; SHR, 1.50; 95% CI, 1.09-2.07), and major adverse cardiac and cerebrovascular events (13.3% vs 8.8%; SHR, 1.50; 95% CI, 1.15-1.95). The subgroup analysis did not demonstrate a variation in mortality between the TEVAR and EVAR cohorts (P for interaction = .725). The dialysis group had higher risks of all-cause mortality and readmission than the CKD without dialysis and non-CKD groups.Among EVAR/TEVAR recipients, CKD was independently associated with higher in-hospital mortality, postoperative complication, and all-cause mortality rates. Patients with end-stage renal disease on dialysis had worse outcomes than those in the CKD non-dialysis and non-CKD groups.
