Peripheral vascular injuries carry significant risk for permanent functional impairment, limb loss, and death. Definitive correction of these injuries requires significant operative time and has traditionally been resource and skill set intensive. In the initial surgical treatment of the physiologically depleted trauma patient, faster techniques may prove more appropriate. Damage control techniques, including vascular shunting, rapidly restore distal flow but require additional vascular intervention and risk shunt thrombosis with prolonged use...

Throughout East and Southern Africa, the WHO recommends voluntary medical male circumcision (VMMC) to reduce heterosexual HIV acquisition. Evidence has informed policy and the implementation of VMMC programmes in these countries. VMMC has been incorporated into the HIV prevention portfolio and more than 9 million VMMCs have been performed. Conventional surgical procedures consist of forceps-guided, dorsal slit or sleeve resection techniques. Devices are also becoming available that might help to accelerate the scale-up of adult VMMC...

BACKGROUND: Multiple failed hemodialysis access and poor vascular anatomy can jeopardize an end-stage renal disease patient's survival, frequently leading to the urgent need for rapid and durable new vascular access. In these circumstances, the extensive use of central venous catheters (CVC) can led to serious complications, such as infection, thrombosis, and often vessel scarring with obstruction of the central veins. More recently, new self-sealing prosthetic grafts may be cannulated within a few days after implantation, avoiding the need for extensive CVC...

BACKGROUND: In recent years, several methods and new techniques have been studied and proposed for establishment of sutureless vascular anastomoses, streaming use of sutureless vascular surgery in the future. PRESENTATION OF THE HYPOTHESIS: The new vascular connector (NVC) is a hypothetical design of a vascular device, proposed for creation and maintenance of sutureless vascular anastomosis. Implication of NVC would introduce a new device and technique in establishment of sutureless vascular anastomosis in which surgical approach is minimized and so post-operation disorders...

Sutureless anastomosis devices are designed to reduce surgical time and difficulty, which may lead to quicker and less invasive cardiovascular anastomosis. The implant uses a barb-and-seat compression fitting composed of one male and two female components. The implant body is resorbable and capable of eluting heparin. Custom robotic deposition equipment was designed to fabricate the implants from a self-curing silk solution. Curing did not require deleterious processing steps but devices demonstrated high crush resistance, retention strength, and leak resistance...

OBJECTIVE: The aim of this study was to assess the safety and short-term effectiveness of a novel hybrid vascular graft used to address renal revascularization during open thoracoabdominal aortic aneurysm (TAAA) repair, performing a sutureless distal anastomosis. METHODS: Between 2012 and 2013, 25 patients (16 men; mean age, 66 ± 8 years) underwent revascularization of one (24 patients) or both (one patient) renal arteries with the Gore Hybrid Vascular Graft (GHVG; W...

To simplify the procedure of blood vessel replacement operation and shorten the vascular anastomosis time, we developed a special artificial blood vessel which can be connected to native blood vessels without suture. The self-made sutureless blood vessel (SMSBV) was made from two titanium connectors and a Gore-Tex graft. To investigate blood compatibility and histocompatibility of the SMSBV, we carried thoracic descending aorta replacement using either SMSBV or Gore-Tex, respectively, in pigs. The aortic clamp time and the operative blood loss in the experimental group (using SMSBV) were less than those in the control group (using Gore-Tex)...

PURPOSE: To present a modification of the Viabahn open revascularization technique (VORTEC) to facilitate right renal artery (RRA) revascularization via a limited thoracotomy and transaortic sheath during endovascular aneurysm repair (EVAR). CASE REPORT: A 51-year-old man with uncontrolled hypertension and limited respiratory reserve presented with a pararenal abdominal aortic aneurysm (AAA) measuring ∼15×8.5×8 cm extending into the iliac arteries. Via a limited low thoracoabdominal incision and retroperitoneal approach, 3 of the renovisceral branches were exposed, but there was difficulty in approaching the RRA...

BACKGROUND: Reconstruction of anomalous left pulmonary veins (ALPV) requires an anastomosis at a nonanatomic position, posing the potential risk of pulmonary vein obstruction (PVO). METHODS: The 514 patients who were diagnosed with a pulmonary vein abnormality from 1990 to 2010 were reviewed. Thirty-eight patients (7.4%; median age, 1.4 years; interquartile range, 0.1 to 5.7 years) were identified. ALPV was diagnosed as an isolated anomaly in 23 (61%) or as part of mixed total anomalous pulmonary venous drainage in 15 (39%)...

Aortic intramural haematoma is similar to classic aortic dissection, which causes a life-threatening medical condition, and immediate diagnosis and treatment are crucial. The optimal therapy for intramural haematoma of the abdominal aorta remains controversial. Conservative medical management is usually the first choice of treatment for uncomplicated cases. Surgical intervention is usually required for complicated intramural haematomas of the abdominal aorta, including conventional open repair and endovascular treatment with stent-grafts...

BACKGROUND: In the first posttransplant month, the most frequent complications are due to technical problems related to complex vascular and bile duct reconstructions during the operation. Moreover, despite great improvements in suturing technique and materials, severe organ ischemia-reperfusion caused by time-consuming hand suturing is still an important factor in graft survival. During the operation, severe hypotension, hypoxic acidosis, hyperkalemia, and renal dysfunction may occur during the anhepatic phase due to the prolonged venous clamping time required for hand suturing...

The classic procedure for aortobifemoral bypass is open surgery. Laparoscopy has been accepted by several authors as a minimal invasive alternative for aortoiliac occlusive disease. The totally retroperitoneal laparoscopic procedure has been described as an alternative to the transperitoneal approach. Whatever the approach, the aortoprosthetic anastomosis is a major difficulty making those techniques unpopular despite obvious advantages for the patients. We report a clampless and sutureless approach for the proximal anastomosis of a totally retroperitoneal laparoscopic aortobifemoral bypass using an EndoVascular REtroperitoneoScopic Technique (EVREST)...

REVIEW
Joseph J Naoum, Elias J Arbid
Polytetrafluoroethylene (PTFE) grafts have proven to be an adequate alternative conduit for peripheral bypass operations. Whether or not one uses PTFE depends on several factors: surgeon preference, individual patient circumstances, or when autologous greater saphenous vein is not available or adequate. These conventional grafts have evolved and undergone modification. The intraluminal surface has been coated with carbon or bonded with heparin. The structure of grafts has been modified with the creation of a hood or cuff, with the incorporation of a stent-graft segment for a sutureless anastomosis, or the fusion of PTFE with an outer polyester layer to minimize suture hole bleeding...

We developed autologous vascular grafts, called "biotubes," by simple and safe in-body tissue architecture technology, which is a practical concept of regenerative medicine, without using special sterile conditions or complicated in vitro cell treatment processes. In this study, biotubes of extremely small caliber were first auto-implanted to rat abdominal aortas. Biotubes were prepared by placing silicone rods (outer diameter 1.5 mm, length 30 mm) used as a mold into dorsal subcutaneous pouches in rats for 4 weeks...

Although improved surgical techniques have led to significantly better outcomes of surgery for total anomalous pulmonary venous connection, the risk of progressive pulmonary venous obstruction continues to be a clinical problem. Both obstructed total anomalous pulmonary venous connection and post-repair pulmonary venous obstruction are associated with a significant risk of recurrent obstruction or death, requiring reoperation for stenosis. In general, side to side anastomosis of the pulmonary venous confluence to the functional left atrium has been performed for supracardiac and infracardiac total anomalous pulmonary venous connection...

PURPOSE: To describe modification of the Viabahn Padova Sutureless (ViPS) technique for challenging anastomosis between a prosthetic graft and a circumferentially calcified target artery. TECHNIQUE: The technique is demonstrated in a 75-year-old man with complete superficial femoral artery (SFA) occlusion and reconstitution of a circumferentially calcified above-knee popliteal artery. A 7-mm Viabahn endoprosthesis with its constraining string was withdrawn from its delivery system; the string at the proximal edge of the stent was gently cut with a scalpel, causing the proximal part of the stent to deploy, while the undeployed distal tip with its smooth profile retained its commercial orientation...

We present a case of an infant with an unroofed coronary sinus associated with a persistent left superior vena cava draining into the left atrium, right superior pulmonary vein stenosis, an atretic left superior pulmonary vein and a double-outlet right ventricle. For pulmonary vein stenosis and atresia, we used a sutureless technique with an autologous pericardial patch to create a neoatrium.

Although arteriovenous fistulae are the preferred form of dialysis vascular access they continue to have significant problems with maturation failure. The Optiflow device is a sutureless anastomotic conduit which could potentially reduce surgical time and also standardize the surgical procedure. We report herein on the "First in Man" experience with the Optiflow device.
