Basilic vein transposition: review of different techniques.

This is a review of the basilic vein procedure and changes that have evolved to improve outcomes. This includes reviewing data on the one-stage vs. two-stage technique as well as elevation for the basilic vein. The review discusses data that help the surgeon decide which technique he should evaluate.

Tips and tricks in creation of forearm arteriovenous fistulae.

Forearm arteriovenous fistula (AVF) is a direct anastomosis between the radial artery and the cephalic vein or the ulnar artery and the basilic vein, which are small-caliber vessels. The surgical technique must be precise to avoid postoperative stenosis of the anastomosis which may result in early thrombosis or nonmaturation. In our experience, microsurgery and preventive hemostasis are two major contributions to creation of forearm AVF. Using these techniques, construction of a radial-cephalic fistula was...

Percutaneous valvulotomy as an alternative to transposition of a brachiocephalic fistula.

Transposition of a deep (9-12 mm) autogenous brachiocephalic vein fistula was required for adequate hemodialysis access in a morbidly obese patient. The patient was a poor candidate for surgical transposition of the upper-arm cephalic vein. As an alternative, retrograde fistula flow was established percutaneously through a 6-F sheath in the forearm cephalic vein with the over-the-wire LeMaitre valvulotome. The retrograde flow in the forearm added 7 cm of superficial vein 6.2-9 mm in diameter with a flow rat...

Anesthesia for vascular access surgery.

The type of anesthesia chosen is an integral part of the decision-making process for arteriovenous access construction. We discuss the different types of anesthesia used, with emphasis on brachial plexus block, which is potentially safer than general anesthesia in this fragile patient population with end-stage renal disease. Brachial plexus block is superior to local anesthesia and enables the use of a tourniquet to minimize potential damage to the blood vessels during anastomosis using microsurgery techniq...

MRI of the brachial plexus: modified imaging technique leading to a better characterization of its anatomy and pathology.

Magnetic resonance imaging (MRI) is the imaging modality of choice for the evaluation of the brachial plexus due to its superior soft tissue resolution and multiplanar capabilities. The evaluation of the brachial plexus however represents a diagnostic challenge for the clinician and the radiologist. The imaging assessment of the brachial plexus, in particular, has been traditionally challenging due to the complexity of its anatomy, its distribution in space and due to technical factors. Herein, we describe...

Is Repeat PTA of a Failing Hemodialysis Fistula Durable?

Purpose. Our objective was to evaluate the outcome of percutaneous transluminal angioplasty (PTA) and particularly rePTA in a failing arteriovenous fistula (AV-fistula). Are multiple redilations worthwhile? Patients and Methods. All 159 stenoses of AV fistulas that were treated with PTA, with or without stenting, during 2008 and 2009, were included. Occluded fistulas that were dilated after successful thrombolysis were also included. Median age was 68 (interquartile range 61.5-78.5) years and 75% were male....

Diffused Aneurysmal Degeneration Of The Brachial Artery After Long-Standing High-Flow Arteriovenous Fistula Closure For Hemodialysis At Elbow Level.

While the possibility of development of a pan-arterial dilatation proximal to a long-standing high-flow post-traumatic arteriovenous fistula is well known, to the best of our knowledge, this event has never been described after vascular access for hemodialysis closure. We describe a singular case of a man in whom a diffused aneurysmal degeneration of the brachial artery has been highlighted six months after longstanding high-flow AVF closure.

Onyx embolization of dural arteriovenous fistulas of the cavernous sinus through the superior pharyngeal branch of the ascending pharyngeal artery.

We report three cases of dural arteriovenous fistula (DAVF) of the cavernous sinus treated by Onyx injection through the superior pharyngeal branch of the ascending pharyngeal artery. The treatment of choice of DAVFs of the cavernous sinus is endovascular, and it is preferentially done via transvenous occlusion of the cavernous sinus. The cavernous sinus can be reached through either the inferior petrosal sinus or the superior ophthalmic vein. When these venous routes are occluded, the first attempt is to p...

Occlusion of brachial pseudoaneurysm after periprosthetic humerus fracture.

Pseudoaneurysms of the brachial artery are rare and most often occur after a penetrating injury. The incidence of periprosthetic humerus fractures is low, and surgical treatment can be demanding. The treatment of choice for an occluded pseudoaneurysm of the brachial artery is saphenous vein bypass. In this article, we report the case of a 73-year-old woman who presented with an occluded pseudoaneurysm of the brachial artery sustained after a neglected periprosthetic humerus fracture. A saphenous vein bypass...

Transposition of the great arteries and sinus venosus defect with partially anomalous pulmonary venous return: physiological and anatomic considerations.

Transposition of the great arteries is a common congenital heart defect causing cyanosis in neonates, occurring in 0.2 per 1000 live births. It has been reported to occur with other associated congenital heart lesions. However, its association with a superior sinus venosus defect and partially anomalous pulmonary venous return has not been reported. We present a neonate with transposition of the great arteries, superior sinus venosus defect with partially anomalous pulmonary venous return that underwent suc...


Giant postnephrectomy arteriovenous fistula in a patient with Tuberous Sclerosis and anomalous inferior vena cava: Treatment with Amplatzer Vascular Plug embolization.

A case of 61 year old woman with Tuberous Sclerosis Complex (TSC) who developed a fistula between renal artery and renal vein following left-side nephrectomy was presented. Additionally an abnormal course of inferior vena cava was detected (type 3 Morito). High flow fistula was causing volume high output heart failure and pulmonary circulation overload with pulmonary hypertension . Due to large size of the fistula it had to be treated with implantation of amplatzer II to the renal artery. The procedure was...

Mechanical enhancement of AVF maturation.

A native arteriovenous fistula (AVF) should be systematically evaluated at 4 to 6 weeks after creation. Any clinical indications of nonmaturation should be promptly followed up and confirmed by detailed duplex ultrasonography looking for a deep vein or inadequate access flow due to stenoses. Once vein depth has been ruled out, a significant stenosis is invariably identified and should therefore be operated on or dilated. Predilation angiography should be performed preferably through the brachial artery. Art...

Native arterio-venous fistula is the vascular access of choice for hemodialysis in end stage renal disease.

THE AIM OF THE STUDY WAS: Is primary Arterio-venous fistula the vascular access of choice for adequate dialysis and better patient outcome in end stage renal disease.

Estimation of central aortic blood pressure: a systematic meta-analysis of available techniques.

Central aortic blood pressure (cBP) is often promoted to be a superior predictor of cardiovascular risk compared to brachial blood pressure, and brachial-central pulse pressure amplification is also suggested as prognostic. Several devices and techniques, each purporting to estimate cBP, have entered commercial use. The interchangeability of cBP measurements between devices and the influence of disease states on central to brachial pulse pressure amplification remain unclear. The useful measurement of cBP i...

Gastropleural fistula in metastatic ovarian cancer.

Gastropleural fistula is a rare condition, most frequently reported as a result of trauma, peptic ulcer disease or malignancy. We report a case of gastropleural fistula in a patient with metastatic ovarian cancer who presented with hydropneumothorax and mediastinal shift. She was successfully managed with an open partial gastrectomy, repair of diaphragmatic defect, and thoracoscopic washout and decortication. Based on our case and review of the literature, surgical repair of gastropleural fistula should be...

Comparison of Graft Patency Between Off-Pump and On-Pump Coronary Artery Bypass Grafting: An Updated Meta-Analysis.

Currently, off-pump coronary artery bypass grafting (OPCAB) and on-pump coronary artery bypass grafting (ONCAB) are 2 well-established therapeutic strategies for patients with coronary artery disease, and debate regarding which strategy provides superior graft patency is ongoing. The current study is a meta-analysis of randomized controlled trials that compared the graft patency between OPCAB and ONCAB.

The "sliding door" technique for closure of abdominal wall defects after rectus abdominis musculocutaneous flap transposition.

Radical surgery is often necessary in patients with local recurrence of rectal cancer or in those with carcinoma associated with an anal fistula. The surgery may include extended excision of the perineal area and can create a large dead space in the pelvis and a large skin defect, often necessitating reconstruction of the pelvic floor using rectus abdominis musculocutaneous (RAM) flap transposition. Wound dehiscence and incisional hernia are common complications of RAM flap transposition. We report herein o...

Superficialization of brachial artery as effective alternative vascular access.

The Japanese Society for Dialysis Therapy recommends superficialization of the brachial artery (BA) as an alternative vascular access (VA) technique in patients for whom a conventional internal shunt (arteriovenous fistula [AVF] or arteriovenous graft) cannot be created. Although 2% to 3% of Japanese hemodialysis patients undergo this procedure, it is not well recognized worldwide. We report here our experience with the procedure, as well as indications, durability, and morbidity.

Use of short prosthesis segments for brachiocephalic arteriovenous fistulas in elderly hemodialysis population.

The autogenous brachiocephalic fistula is a recognized secondary access for hemodialysis. However, veins in the antecubital fossa are often damaged, due to repeated venipunctures and subsequent scarring. Sometimes their anatomy does not enable successful arteriovenous fistula creation. In cases when the proximal part of the cephalic vein seemed patent, during ultrasound Doppler examination, we decided to use a short segment of 6 mm polytetrafluoroethylene graft to connect the vein with the brachial artery....

Pancreaticogastrostomy Is Superior to Pancreaticojejunostomy for Prevention of Pancreatic Fistula After Pancreaticoduodenectomy: An Updated Meta-analysis of Randomized Controlled Trials.

To review prospective randomized controlled trials to determine whether pancreaticogastrostomy (PG) or pancreaticojejunostomy (PJ) is associated with lower risks of mortality and pancreatic fistula after pancreaticoduodenectomy (PD).

Is Surgery for Brachial Plexus Schwannomas Safe and Effective?

Schwannomas rarely are found in the brachial plexus, and although they are benign, they present significant challenges to surgical treatment. To our knowledge, there are few studies investigating the surgical outcomes of patients with brachial plexus tumors.

Endobronchial valve placement for the treatment of bronchopleural fistula: a review of the current literature.

Bronchopleural fistula is a cause of increased morbidity and mortality. Patients who develop bronchopleural fistula after lung resection or spontaneous pneumothorax often have multiple co-morbidities making them poor candidates for repeated surgical intervention. Previous nonsurgical treatments for bronchopleural fistula have had limited success. Endobronchial valves, originally designed for bronchoscopic lung volume reduction, have been used under a humanitarian use exception for the treatment of bronchopl...

Predicting women at risk for developing obstetric fistula: a fistula index? An observational study comparison of two cohorts.

To ascertain if a predictor of obstructed labour and obstetric fistula (OF) occurrence could be devised.

Analysis of mutations in 7 candidate genes for dextro-Transposition of the great arteries in Chinese population.

Transposition of great arteries (TGA) represents the most frequent cyanotic heart defect diagnosed in the neonatal period. Several genes had been identified to be associated with the pathogenesis of dextro-transposition of the great arteries (d-TGA). These genes are located in different chromosomes and their mutations can only explain few clinical cases. Besides, no genetic scan for TGA has been implemented in China.
