Abstract Introduction Vascular access for invasive cardiac investigations has traditionally been gained from the femoral vessels, however, a “radial-first” approach has become increasingly popular for coronary interventions [1]. Transradial access has shown lower complication rates, shorter admission times, and reduced healthcare costs for coronary interventions [4]. A “superior” approach via the jugular and subclavian veins have been reported for electrophysiology (EP) studies and radiofrequency catheter ablation (RFCA) but is associated with an increased risk of complications such as pneumo- and haemothorax [9]. Purpose EP procedures often require the use of both venous and arterial catheters, and the potential advantage of non-femoral peripheral access is yet to be investigated. This study was performed to provide comprehensive anatomical evidence that the vessels of the arms are suitable for use during EP procedures, as assessed by vascular ultrasound. Methods A portable ultrasound device was used to measure the diameter of the brachial artery, brachial vein, basilic vein & cephalic vein on the left and right upper limbs of 63 healthy adult volunteers. Measurements were also taken of the circumference at the elbow and at the mid-bicep level on both arms. A subgroup of 15 volunteers had additional measurements taken of the same veins and artery on both arms with a tourniquet at the upper bicep level. Results The basilic vein was found to have the largest diameter with a median of 4.6 mm and 4.5 mm (right and left diameter, respectively), followed by the cephalic (median of 3.1 and 3.0 mm) and the brachial vein (median of 2.8 mm for both arms). 100% of volunteers had at least one vein that was equal to a 3 mm diameter (which would allow for a 8F sheath insertion), with 98% having 2 suitable veins and &gt;80% having 3 suitable venous vessels. More than 90% had a suitable diameter of more than 3 mm for both the right and left brachial artery. There was significant correlation between gender, and basilic vein and brachial artery diameters. There was no correlation between BMI, height, weight and elbow or bicep circumference. Conclusion To our knowledge, this is the first study to investigate the feasibility of adopting peripheral access in the electrophysiology lab. 100% of volunteers examined had one vein which was at least 3mm in size and would be suitable for 8F sheath insertion. We demonstrate the anatomic evidence that the vessels in the arm are capable of housing the size of sheath and catheters commonly used in the EP lab.

A brachio-brachial arteriovenous fistula with superficialization of the brachial vein and superficialization of the brachial artery are useful vascular access techniques for hemodialysis patients. However, both typically require a long skin incision from the antecubital fossa toward the axillary fossa. In addition, the brachio-brachial arteriovenous fistula in particular, which is created with not a one-stage but a two-stage procedure, requires a relatively long time of 2–3 months before it can be used for hemodialysis. Furthermore, superficialization of the brachial artery usually requires nonarterialized superficial veins for blood return. In cases where patients have no adequate superficial veins for creating an arteriovenous fistula, we have adopted a one-stage operative technique to create a brachio-brachial arteriovenous fistula with superficialization of not only the brachial vein but also the brachial artery using a short skin incision. This technique of a brachio-brachial arteriovenous fistula with superficialization of the brachial artery has several advantages over traditional approaches, including a minimally invasive procedure and early use for vascular access. To our knowledge, the presently described technique and the related data have not been previously reported in the English literature. We herein report the steps of this technique and the midterm follow-up outcomes.

Venous Fistula

Native arterio-venous fistulas (AVFs) are preferred for hemodialysis vascular access over synthetic grafts and long-term catheters. However, prevalence rates of native AVFs are variable around the world and have increased only slightly in United States since the DOQI guidelines. To increase rates of native AVFs, pre-operative vascular mapping by ultrasound has been found of major help for appropriate selection of the vessels. The minimal desirable lumen diameter of the artery should be > 2 mm and > 2.5 to 3 mm for the vein at the anatomosis. Early failure can be reduced to less than 10% when the feeding artery is > 2 mm, even in diabetics. If sizes of the vessels are smaller than those targets at the wrist, moving to the upper arm should be considered. The interval between creation and first cannulation varies from 2 weeks to 4 months. There might not be much advantage to wait for more than 4 weeks; however, in large dialysis units, observing a delay of 4 to 6 weeks may be worthwhile to avoid initial problems such as infiltrations and lacerations. Access flow monitoring is essential since it is a reliable predictor of vascular access dysfunction, reducing associated morbidity and costs. Early monitoring of recently created native AVFs has shown that the increase in intra-access blood flow occurs very soon after construction and becomes maximal after a few weeks. A recent prospective study involving all new native AVFs monitored by ultrasound-dilution between weeks 6 and 10 after creation, and every 3 to 6 weeks over 4 months, showed no statistically significant difference in access blood flow between the initial and final measurements (respective values of 1132 ± 681 and 1097 ± 644 ml/min). Access flow was higher in males, and in brachio-cephalic compared to radio-cephalic AVFs. Over the long-term, AVFs are associated with longer patency and lower complication rates, and efforts should be directed at further increasing their prevalence.

In the current scenario, propeller flaps are an attractive choice for single stage coverage of a large number of defects. They have a more reliable vascular pedicle than traditional flap and allow for greater freedom in design and wide mobilization and minimal donor-site morbidity. Harvesting of a propeller flap requires appropriate patient selection, preoperative planning, and meticulous dissection and these techniques greatly reduce the complication rates. Here, we present a case of a post burn raw area of the right axilla which was debrided and covered with a brachial artery perforator propeller flap.

Introduction: Direct Superior Approach (DSA) is a muscle sparing approach for total hip arthroplasty (THA) implemented using special instrumentation. There is a lack of information in the literature concerning DSA with standard instrumentation. Materials and methods: 238 patients were recruited for primary THA by a single surgeon from January 2016 until May 2017. 209 patients underwent THA through DSA approach with non-offset acetabular reamers and femoral broaches. We evaluated accuracy of implantation, complications and early functional results. Independent orthopaedic surgeons performed the clinical and radiographic assessments. Results: 200 patients were followed for a year. 3 different implants were used. No sciatic nerve palsies, hip dislocations or fractures were recorded. There was one acute deep and superficial wound infection. The mean functional score was significantly improved at all follow-ups ( p < 0.001). 97% of stems were inserted into the neutral coronal and 96% in neutral sagittal alignment. All cups fell within a safe zone of inclination and 91% of anteversion. 2 hips demonstrated heterotopic ossification, Brooker class I. Obese patients had no increased risk of complications. Conclusions: DSA with standard instrumentation is safe and efficacious for THA. It offers fast recovery and facilitates correct implantation of different implants, can be useful even for hip dysplasia and obese patients with minimal complication rates.

Abstract The Japanese Society for Dialysis Therapy recommends superficialization of the brachial artery (BA) for vascular access in patients with comorbidities. We describe a novel minimal incision superficialization surgery of a BA through a single small incision. A 78-year-old male, who underwent chronic hemodialysis through an arterio-venous fistula, was transferred to our hospital for treatment of heart failure. We chose superficialization of the right BA for new vascular access. Under tumescent local analgesia, though a single 2-cm long incision, the BA was superficialized for 10-cm long. To complete procedures in the narrow and deep space, vessel branches were ligated by vascular clip and knot-less barbed suture was applied for closure of the brachial fascia beneath the BA. The hemodynamic status during the hemodialysis improved and the New York Heat Association (NYHA) classification grade improved from IV to II. This technique can be an alternative for arterio-venous fistula in patients with comorbidities.

Abstract There exist wide anatomical variations of upper limb. Their implication is perhaps greatest when it comes to failure of arteriovenous fistula (AVF) for chronic hemodialysis. Among arteries of forearm, brachial artery is of note, whose high bifurcation is associated with increased risk of failure. The superficial and accessory variants also cause difficulty for the surgeon. The single unpaired brachial vein and stenosis of cephalic vein compound the difficulties associated with AVF among many others. A thorough understanding of surgeons regarding normal anatomy and diverse variants holds high importance in context of deciding an appropriate site for arteriovenous (AV) anastomosis. Negligence in creation of fistula not only pose a threat to patients of end stage renal disease (ERSD) but also contributes to numerous other complications involving nerves and drug administration.

Deep endometriosis infiltrating the rectum remains a challenging situation to manage, and it is even more important when ureters and pelvic nerves are also infiltrated. Removal of deep rectovaginal endometriosis is mandatory in case of symptoms strongly impairing quality of life, alteration of digestive, urinary, sexual and reproductive functions, or in case of growing. Extensive preoperative imaging is required to choose the right technique between laparoscopic shaving, disc excision, or rectal resection. When performed by skilled surgeons and well-trained teams, a very high majority of cases of deep endometriosis nodule (>95%) is feasible by the shaving technique, and this is associated with lower complication rates regarding rectal resection. In most cases, removing a part of the rectum is questionable according to the risk of complications, and the rectum should be preserved as far as possible. Shaving and rectal resection are comparable in terms of recurrence rates. As shaving is manageable whatever the size of the lesions, surgeons should consider rectal shaving as first-line surgery to remove rectal deep endometriosis. Rectal stenosis of more than 80% of the lumen, multiple bowel deep endometriosis nodules, and stenotic sigmoid colon lesions should be considered as indication for rectal resection, but this represents a minority of cases.

Background: To evaluate prospectively the results obtained in 28 patients undergoing laparoscopic pyeloplasty through transperitoneal access.Methods: From January 2014 to June 2016, twenty-eight patients between 12 and 55 years old underwent laparoscopic pyeloplasty for primary ureteropelvic junction (UPJ) obstruction via a transperitoneal approach. Eighteen cases had the obstruction on the left side and the other ten on the right side. All patients had radiographic evidence of obstruction with signs, symptoms or deterioration of renal function. Anderson-Hynes dismembered pyeloplasty was performed in 25 patients and Fenger technique in the other 3 cases. Three patients had non-obstructing renal stones and underwent concomitant pyelolithotomy.  Patients were evaluated clinically and by imaging in the postoperative period at 3 and 6 months and then followed-up annually.Results: The operative time ranged from 190 to 330 min. The average blood loss was 70 mL. Analgesic requirements were also minimal with patients requiring PCA for an average of 1.1 days. Average days to free fluids were 1.5 days. The mean hospital stay was 3.76 days. The time to return to normal activities ranged from 7 to 12 days. Crossing vessels were identified in 16 patients, intrinsic stenosis in 14 patients and 5 patients had high implantation of the ureter. There were no conversions to open. One patient had longer urinary fistula (9 days), 2 patients had prolonged ileus and 3 patients had port site infection. The follow up ranged from 6 to 72 months. From the later postoperative complications, 2 patients had re-stenosis. The success rate was 92.85%.Conclusions: Laparoscopic pyeloplasty has functional results comparable to conventional open technique. It offers less morbidity, with aesthetic and post-operative convalescence benefits and lower complication rates.
