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...

Arterio venous fistula experience at a tertiary care hospital in Pakistan.

Objective: To evaluate the two year patency rate of functioning arteriovenous fistula. Methodology: This prospective case series study was conducted at Department of Urology, Jinnah Postgraduate Medical Centre, Karachi, from 1(st) January 2009 to 31(st) December, 2010. Patients were chosen for CBRC arteriovenous fistula at wrist and patients undergoing other types of vascular access or secondary fistula formation were excluded. Results: One hundred and eighty two patients underwent arteriovenous fistula for...

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.

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...

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...


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....

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.

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.

Brachial plexopathy: a review of traumatic and nontraumatic causes.

OBJECTIVE. This article reviews brachial plexus anatomy in the context of key landmarks, illustrates common findings of traumatic and nontraumatic causes of brachial plexopathies, describes symptoms associated with these maladies, and explains how proper diagnosis impacts clinical decisions. CONCLUSION. Knowledge of brachial plexus anatomy and of the imaging sequelae of traumatic and nontraumatic plexopathies enables the radiologist to more easily identify these afflictions, thereby facilitating a multidisc...

Mirizzi Syndrome Type II with Cholecystoduodenal Fistula: An Infrequent Combination.

We report a case of Mirizzi syndrome type II associated with biliary enteric fistula. It is important to identify this combination early, as it is associated with high morbidity. In our case, intraoperative findings were cholecystoduodenal fistula and communication of Hartmann's pouch with common bile duct (CBD). A subtotal cholecystectomy with excision of cholecystoduodenal fistula was performed. A minimal surgical maneuver of Calot's Triangle with repair of cholecystoduodenal fistula is required during th...

Central blood pressure: current evidence and clinical importance.

Pressure measured with a cuff and sphygmomanometer in the brachial artery is accepted as an important predictor of future cardiovascular risk. However, systolic pressure varies throughout the arterial tree, such that aortic (central) systolic pressure is actually lower than corresponding brachial values, although this difference is highly variable between individuals. Emerging evidence now suggests that central pressure is better related to future cardiovascular events than is brachial pressure. Moreover, a...

Treatment of complex atherosclerotic femoropopliteal artery disease with a self-expanding interwoven nitinol stent: midterm results from the Leipzig SUPERA 500 registry.

Aims: To examine the efficacy and durability of an interwoven self-expanding nitinol stent in the treatment of complex femoropopliteal artery lesions in unselected patients. Methods and results: Five hundred and twenty-seven limbs in 470 patients with femoropopliteal arterial disease were treated with SUPERA stents. Follow-up data were prospectively collected in a single-centre registry and were available for 439 patients (492 limbs). The patients were followed by Doppler ultrasound, stent roentgenograms, e...

Arterial pressure: agreement between a brachial cuff-based device and radial tonometry.

Aortic (central) blood pressure (BP) differs from brachial BP and may be a superior predictor of cardiovascular events. However, its measurement is currently restricted to research settings, owing to a moderate level of operator dependency. We tested a new noninvasive device in a large UK cohort. The device estimates central BP using measurements obtained with an upper arm cuff inflated to suprasystolic pressure. We compared these estimates with those obtained using radial tonometry as well as with invasive...

The effect of graft configuration on 30-day failure of infrapopliteal bypasses.

Despite advances in endovascular techniques, infrapopliteal bypasses are still required for limb salvage. Short-term graft patency is an important outcome parameter reflecting technical considerations and acute graft thrombosis. Both are important prerequisites for long-term patency. In this analysis, we compared the 30-day patency of all conduit configurations for infrapopliteal bypasses.

Supratricuspid obstructive membrane in congenitally corrected transposition of the great arteries.

Obstructive lesions in the inflow of the systemic ventricle in congenitally corrected transposition of the great arteries are rare. It is important to identify such lesion which could alter the surgical outcome if not recognized. We report the echocardiographic findings in a patient with supratricuspid obstructive membrane with corrected transposition of the great arteries.

Endovascular repair of a ruptured subclavian artery aneurysm in a patient with Ehlers-Danlos syndrome using a sandwich technique.

We present the case of a type IV Ehlers-Danlos syndrome patient with a ruptured right subclavian artery aneurysm and associated arteriovenous fistula who underwent successful endovascular repair requiring simultaneous stent graft repair of the innominate artery using a sandwich technique. A 17-year-old man with known type IV Ehlers-Danlos syndrome developed right neck and shoulder swelling. CTA study demonstrated a 17 × 13-cm ruptured subclavian artery aneurysm with an associated internal jugular vein...

Knowledge of Obstetric Fistula Prevention amongst Young Women in Urban and Rural Burkina Faso: A Cross-Sectional Study.

Obstetric fistula is a sequela of complicated labour, which, if untreated, leaves women handicapped and socially excluded. In Burkina Faso, incidence of obstetric fistula is 6/10,000 cases amongst gynaecological patients, with more patients affected in rural areas. This study aims to evaluate knowledge on obstetric fistula among young women in a health district of Burkina Faso, comparing rural and urban communities. This cross-sectional study employed multi-stage sampling to include 121 women aged 18-20 yea...

Proper Hepatic Artery Reconstruction With Gastroduodenal Artery Transposition During Pancreaticoduodenectomy.

Introduction. Vascular injuries to hepatic arterial blood flow present a challenge in reconstruction. The location and extent of the injury dictate intraoperative decision making, with repair being performed expeditiously to preserve hepatic function. Formal arterial repair either primarily or with interposition or transposition grafts is indicated in the majority of patients. Special consideration should be made in patients with underlying liver disease and those undergoing biliary reconstructions. This la...

Origin of medial and lateral pectoral nerves from the supraclavicular part of brachial plexus and its clinical importance - a case report.

Knowledge of normal and anomalous formation of brachial plexus and its branches is of utmost importance to anatomists, clinicians, anesthesiologists and surgeons. Possibility of variations in the origin, course and distribution of branches of brachial plexus must be kept in mind during anesthetizing the brachial plexus, mastectomy and plastic surgery procedures. In the current case, the medial pectoral nerve arose directly from the middle trunk of the brachial plexus and the lateral pectoral nerve arose fro...
