The population of end-stage renal failure patients dependent on hemodialysis continues to expand with an increasing number of patients having an unsuitable cephalic vein or failed radio- and brachio-cephalic fistula. In these patients, the transposed basilic vein to brachial artery arteriovenous fistula (BaVT) provides autologous choice for hemodialysis. The results of basilic vein transposition arteriovenous fistula were assessed.
The aim of this paper was to present our 3-year multicenter experience in creating a vascular access using the basilic vein. The third choice in creating vascular access is the brachiobasilic arteriovenous fistula (AVFs) with transposition of the basilic vein.
The objective of this study was to analyse the outcome of autogenous brachiocephalic fistula for dialysis purposes and to determine modifiable and non-modifiable patient-related factors of influence on the patency of a newly created fistula.
In patients with a high risk of fistula immaturity, we created arteriovenous fistulas (AVFs) combined with brachial artery superficialization. With this procedure, the superficialized arteries are used as drawing routes and the AVFs as returning routes. This is a technical report about AVFs combined with brachial artery superficialization.
Most guidelines recommend the creation of arteriovenous fistula (AVF) in patients with chronic kidney disease (CKD) stage 4. However, an increasing number of studies suggest that early AVF creation leads to high rates of AVF failure and death before dialysis commencement. Only the Japanese guideline recommends AVF creation at CKD stage 5; however, no data are available regarding access-related outcomes at this stage.
The aim of this article is to assess and compare the rate of primary patency achieved by drug-eluting balloon angioplasty (DEBA) and conventional balloon angioplasty (CBA) in hemodialysis arteriovenous fistula stenoses.
The objective was to assess the outcomes of a one-stage approach to bladder stones in the setting of a vesicovaginal fistula, performing fistula repair concurrently with stone extraction.
To prospectively evaluate the perioperative safety, early complications and satisfaction of patients who underwent the implantation of central catheters peripherally inserted via basilic vein.
Whether statins improve arteriovenous fistula (AVF) outcomes is still a matter of debate. Taking into consideration the existing physicochemical differences between individual drugs, this study evaluates the impact of three different statins (atorvastatin, rosuvastatin and simvastatin) on one-stage and two-stage AVF outcomes.
Autogenous fistulas and in particular radiocephalic fistulas are recommended as the first vascular access for hemodialysis. Unfortunately, the rates of early failure and non-maturation are very high. For more than a decade, brachial plexus block has been proposed as the anesthesia of choice for fistula creation due to its beneficial sympathectomy-like effect, causing vasodilation and attenuation of spasm. Until recently, there was not a single randomized clinical study supporting this proposition. Because p...
We describe the use of time-resolved MR angiography in the diagnosis of cervical epidural arteriovenous fistula before final diagnosis and embolization was achieved by digital subtraction angiography. A 42-year-old woman was referred to us because of headache and dizziness, in addition to radiculopathy of the right superior limb. Angiographic examinations documented a direct high-flow arteriovenous fistula between the right vertebral artery and the cervical epidural venous plexus. The point of fistula was l...
Endothelial dysfunction is considered the first stage in the development of atherosclerosis and cardiovascular disease, and brachial flow-mediated dilation (FMD) is a measure of endothelial function. It is uncertain which of central systolic aortic pressure (CAP) or brachial systolic blood pressure (SBP) is more strongly associated with FMD. Therefore, we examined the correlations of CAP and SBP with FMD in Japanese men.
The patency capsule is designed to evaluate the patency of the small bowel before administration of small-bowel capsule endoscopy (SBCE) in patients at high risk of retention. The utilization of a patency capsule may be associated with a risk of symptomatic retention, but very few cases have been reported to date. The aim of our study was to describe our experience with this rare complication of a patency capsule.
An 86-year-old man with a long-term habit of ethanol consumption was admitted due to massive transudate ascites and leg edema. Abdominal computed tomography revealed a dilated main pancreatic duct and atrophied pancreatic parenchyma, leading to the diagnosis of chronic pancreatitis. Moreover, the portal vein was enhanced in the early arterial phase, which indicated the presence of an arterioportal fistula. The fistula was located between the posterior superior pancreaticoduodenal artery and the portal vein ...
Coronary artery fistula is a rare anomaly; large fistulae may result in myocardial ischemia from coronary steal. We present the case of a 73-year-old male who presented with exertional angina; imaging demonstrated severe coronary artery disease and a large coronary artery fistula. Ligation of the fistula resulted in severe right ventricular failure and cardiogenic shock. After reestablishing flow to the fistula, the patient recovered. We speculate that the ischemia-induced angiogenesis from the congenitally...
Pulmonary hypertension (PH) is an increase in pulmonary arterial pressure secondary to narrowing and obliteration of the lumen of the lung vessels resulting in an increased resistance to flow. It is defined by a mean pulmonary arterial pressure (mPAP) ≥25 mmHg at rest usually confirmed by right heart catheterization compared with normal mPAP of ≤20 mmHg. The primary etiology of PH is unclear, although it can be from heart, lung or systemic disease. Patients with End-Stage Renal Disease (ESRD) are at inc...
Objective: Toe-brachial index (TBI) is usually measured in the great toe (TBI-1). However, this is not always possible. To determine the usefulness of TBI measurement in the second toe (TBI-2), we examined the relation between systolic pressure in the second toe (toe pressure [TP-2]) and that in the great toe (TP-1) and evaluated the association between TBI and ankle-brachial index (ABI). Materials and Methods: We retrospectively analyzed patients who underwent a series of measurements of TBI-2, TBI-1, and ...
Complex aortic aneurysm such as paravisceral aneurysm represent a challenging condition especially in the case of rupture. The presence of an aortoenteric fistula in this setting is associated with a very high mortality and morbidity. We report the case of a 72-year-old patient with contained ruptured paravisceral aortic aneurysm who underwent surgeon-modified fenestrated EVAR (sm-fEVAR) with fenestrations for multiple renal arteries and the superior mesenteric artery. The patient successfully recovered fro...
The ankle-brachial index (ABI) is the ratio of the ankle versus brachial systolic blood pressure. ABI of
Flap transposition is an infrequent but far from exceptional thoracic surgical procedure. The aim of this retrospective study was to report our experience in a referral unit of general thoracic surgery analyzing the early results after flap transposition.
Esophageal atresia (EA) and tracheoesophageal fistula (TEF) consist of a spectrum of rare congenital abnormalities. Although EA surgical treatment is well established, the outcome of EA with proximal fistula (type B and D EA) or isolated H-type fistula (type E EA) is poorly explored. These forms of EA shared a common surgical step: the need of a cervical approach to close the fistula. Therefore, the aim of present study is to evaluate postoperative outcomes of patients treated for Gross type B-D and E EA, o...
Shoulder surgery is often performed with the patient in the so called "beach-chair position" with elevation of the upper part of the body. The anesthetic procedure can be general anesthesia and/or regional block, usually interscalenic brachial plexus block. We present a case of brachial plexus palsy with a possible mechanism of traction based on the electromyographic and clinical findings, although a possible contribution of nerve block cannot be excluded.
Our study aimed to explore whether the ankle-brachial index (ABI) and brachial-ankle pulse wave velocity (baPWV) were associated with albuminuria in community-based Han Chinese.
In this report we describe a patient with anterior renal nutcracker syndrome caused by extrinsic compression of the left-sided inferior vena cava between the aorta and the superior mesenteric artery, as it crossed the midline, with resultant left renal vein hypertension. The patient was successfully treated by transposition of the right ovarian vein, which created a bypass of the compressed inferior vena cava and resulted in complete resolution of symptoms.
