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.
Use of the forearm basilic vein for the creation of an arteriovenous fistula has been codified as second choice vascular access for hemodialysis in the last clinical guidelines of the Society for Vascular Surgery in 2008. Poor literature data on this technical option and on its evaluation and outcomes led us to initiate a retrospective single-center study.
Introduction Subjects who undergo haemodialysis are living longer, which necessitates increasingly complex procedures for formation of arteriovenous fistulas. Basilic veins provide valuable additional venous 'real estate' but surgical transposition of vessels is required, which required a cosmetically disfiguring incision. A minimally invasive transposition method provides an excellent aesthetic alternative without compromised outcomes. Methods A retrospective review was made of minimally invasive brachioba...
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.
Tracheogastric tube fistulas are rare but fatal complications after esophagectomy. Anesthetic management for a patient with this complication is challenging because air leakage and mechanical ventilation may cause aspiration. We present a case report of the anesthetic management of a patient having 2-stage surgical repair combined with endoscopic mucosal resection for a giant carinal tracheogastric tube fistula. The first stage was separation of the gastric tube above the fistula with spontaneous breathing ...
Non-maturation and post-maturation venous stenosis are the primary causes of failure within arteriovenous fistulae (AVFs). Although the exact mechanisms triggering failure remain unclear, abnormal hemodynamic profiles are thought to mediate vascular remodelling and can adversely impact on fistula patency.
BACKGROUND Although the proximal radial artery has been reported as an alternative inflow to prevent steal syndrome, brachiobasilic fistula has been reported to be associated with steal syndrome in 10-20% of cases. We aimed to compare proximal radiobasilic arteriovenous fistula (AVF) with brachiobasilic AVFs on the upper arm in terms of steal syndrome and outcomes. MATERIAL AND METHODS We used our institutional operative record database to identify 94 patients in whom brachiobasilic AVF (n=40) and radiobasi...
In this series, the authors describe a modification of the facial artery musculomucosal flap for oronasal fistula repair. The spacer facial artery musculomucosal flap technique is characterized by a pedicle inset into the retromolar trigone and palate, obviating a second operative stage. This was performed in 14 patients with a 5.2-cm mean fistula size. Average follow-up was 4.3 years, with one partial flap necrosis but no recurrent oronasal fistula. There was a mean decrease of 18 percent in the distance b...
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...
We aimed to assess graft patency in patients undergoing prosthetic graft interposition of the brachiocephalic veins (BCVs) or the superior vena cava (SVC) combined with resection of malignant tumours.
Arterioenteric fistulas are a rare cause of massive gastrointestinal hemorrhage. We present a patient who developed a fistula between a middle colic artery pseudoaneurysm, a proximal branch of the superior mesenteric artery (SMA), and the third part of the duodenum 2 weeks after a self-inflicted gunshot wound to the abdomen. The patient's presentation, evaluation, treatment, and prognosis are discussed. All prior published cases of SMA-duodenal fistulas are reviewed.
Resection and reconstruction of the superior vena cava (SVC) is used for the complete resection of advanced lung cancer and mediastinal tumors. However, the optimal postoperative management for this procedure remains to be elucidated.
Despite being one of the most prevalent cardiac arrhythmias, the cause of atrial fibrillation (AF) in a vast majority of patients remains unknown. There is growing evidence of associated AF in patients diagnosed with coronary arteriovenous fistula. In this discussion, we have included an example of a patient who presented with new-onset AF and was subsequently diagnosed with an anomalous fistula between the right coronary artery and the superior vena cava. Definitive treatment of the fistula resulted in per...
This study aimed to assess whether markers of coagulation, fibrinolysis or thrombophilia are increased in children on haemodialysis compared with controls and whether measurement of any of these factors could help to identify patients at an increased risk of arteriovenous fistula (AVF) occlusion. Blood samples were taken from 55 children immediately before a session of haemodialysis and from 20 healthy volunteers. Thrombin-antithrombin (TAT), D-dimer, plasmin-antiplasmin (PAP) and anticardiolipin immunoglob...
Currently, staged procedures involving stoma formation and closure are the widely accepted treatment for newborns suffering from anorectal malformations (ARM) with recto-urethral fistula. This study aims to evaluate the safety and efficacy of one-stage single-incision laparoscopic-assisted anorectoplasty (SILAARP) as an alternative to the conventional approach.
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...
Ligation of Intersphincteric Fistula Tract vs Ligation of the Intersphincteric Fistula Tract Plus a Bioprosthetic Anal Fistula Plug Procedure in Patients With Transsphincteric Anal Fistula: Early Results of a Multicenter Prospective Randomized Trial.
The purpose of this study was to compare the ligation of intersphincteric fistula tract (LIFT) with an additional plug (LIFT-plug) in the treatment of transsphincteric anal fistula.
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...
Interscalene brachial plexus blocks are performed for perioperative management of surgeries involving the shoulder. Historically, these procedures employed anatomic landmarks (AL) to determine the location of the brachial plexus as it passes between the anterior and middle scalene muscles in the neck. In this study, we compared the actual location of the brachial plexus as found with sonography (US) to the anticipated location using AL.
Perianal fistula formation is a rare complication in children after rectal biopsy. Perianal fistula may become difficult to treat; therefore a lot of surgical options are present. One of these options is video assisted anal fistula treatment (VAAFT). We present a 6-year-old female who developed perianal fistula following rectal biopsy for which VAAFT was done successfully.
Corrected transposition is a relatively uncommon congenital heart defect characterized by discordance at both the atrioventricular and ventriculoarterial levels. A rare subset of patients with corrected transposition also have criss-cross atrial morphology. We report the surgical treatment of 2 patients with corrected transposition in association with criss-cross atrial morphology, emphasizing the novel atrial baffle required for this operation.
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.
