INTRODUCTION: Endoleaks are a well-known complication after endovascular aortic repair. Type I endoleak-like phenomenon (also defined as a proximal pseudoaneurysm) post-open abdominal aortic aneurysm (AAA) repair is described as an anastomotic leak causing recurrent pressurization of the original aneurysm sac. It is rare but may result in aneurysmal sac rupture into the peritoneal cavity. REPORT: A 78-year-old man presented with a progressively enlarged aneurysmal sac due to proximal anastomotic degeneration of the proximal suture line associated with an outflow through a patent large lumbar vessel following a previous emergency open AAA repair...

Subintimal angioplasty of lower limb arterial occlusion carries a relatively higher risk of vessel perforation compared to transluminal angioplasty. Vessel perforation is a potentially life threatening complication which requires prompt recognition and management. They are usually managed by endovascular techniques such as low-pressure balloon tamponade, covered stents, and coil embolization of the ruptured artery. We describe a technique of treating vessel perforation following balloon angioplasty. Patient developed a large perforation of the proximal superficial femoral artery (SFA) after balloon inflation during subintimal angioplasty of complete SFA occlusion...

Introduction Splenectomy in children is nowadays widely performed by laparoscopy, the major risk being operative hemorrhage. We hereby compare the results of two different techniques of vascular control. Materials and Methods We retrospectively reviewed all patients undergoing a laparoscopic splenectomy (LS) for hematologic disease at a single institution from 2004 to 2013. LS was performed by a lateral approach. The 10-mm optic port was placed in the umbilicus and two 5-mm working ports were placed in the left lower quadrant and in the right upper quadrant near the midline...

The inhibition effects of ultrafine water mists on 6.5%, 8%, 9.5%, 11%, and 13.5% methane explosions were experimentally studied in a sealed visual vessel. The mist (10μm) produced by a mist generation system in the vessel was measured by a phase doppler particle analyzer. A high-speed camera was used to record the explosion flame affected by spraying concentration and a high frequency pressure sensor was used to acquire the explosion pressure. Meanwhile, the relationship between flame propagation and pressure rising with time was analyzed...

REVIEW
Zachary W Kostun, Edward Y Woo
Endovascular aneurysm repair has enabled a broad population of patients with infrarenal abdominal aortic aneurysm to be treated by a less-invasive technique. However, endovascular aneurysm repair has therapeutic limitations, including the need for lifelong surveillance and a higher rate of secondary interventions than open repair. These outcomes can promote patient dissatisfaction and result in increased health care costs and associated morbidity and mortality. The primary reason for secondary interventions is continued abdominal aortic aneurysm sac enlargement due to endoleaks...

A 68-years-old male with diabetes mellitius (HbA1c 6.5%) was referred for coronary artery bypass grafting(CABG). Preoperative coronary angiography (CAG) signed 3-vessels coronary disease[#2 75 %,#4 posterior descending (PD) 75%,#6 90%,#14 90%]. Minimally invasive coronary artery grafting (MICS CABG) was selected because of faster postoperative recovery than off-pump CABG via a 10 cm left 5th thoracotomy approach. In situ bilateral internal thoracic artery(BITA) and saphenous vein (SVG) was harvested by special manner using long type Harmonic...

BACKGROUND: Bipolar vessel sealing is an efficient electrosurgical procedure for the occlusion of blood vessels particularly during minimally invasive surgery. Reliable knowledge of the thermal spread is crucial for a safe application of bipolar vessel sealing instruments when operating close to thermo-sensitive structures, such as nerves. The evolution of the thermal spread over time and space depends on a variety of parameters, such as the biological tissue, the energy applied to the tissue, and the geometry of the vessel sealing instrument...

Despite being a small part of the world's oceans, the Mediterranean Sea hosts a diverse marine mammal fauna, with a total of 28 different species known to occur, or to have occurred, in the region. Species currently recognised as regular in the Mediterranean-the Mediterranean monk seal (Monachus monachus) and 11 cetaceans (fin whale, Balaenoptera physalus; sperm whale, Physeter macrocephalus; Cuvier's beaked whale, Ziphius cavirostris; short-beaked common dolphin, Delphinus delphis; long-finned pilot whale, Globicephala melas; Risso's dolphin, Grampus griseus; killer whale, Orcinus orca; striped dolphin, Stenella coeruleoalba; rough-toothed dolphin, Steno bredanensis; common bottlenose dolphin, Tursiops truncatus; harbour porpoise, Phocoena phocoena relicta) have adapted well to the region's environmental conditions, but their coexistence with humans is problematic...

The primary function of platelets is to patrol the vasculature and seal vessel breaches to limit blood loss. However, it is becoming increasingly clear that they also contribute to pathophysiological conditions like thrombosis, atherosclerosis, stroke and infection. Severe sepsis is a devastating disease that claims hundreds of thousands of lives every year in North America and is a major burden to the public health system. Platelet surface receptors like GPIb, αIIbβ3, TLR2 and TLR4 are involved in direct platelet-bacteria interactions...

VATS lobectomy is a safe and effective treatment strategy for operable stage I and II lung cancer. It has a similar five-year survival compared to open lobectomy (thoracotomy). VATS lobectomy is associated with less postoperative complications and shorter hospital length of stay when compared to lobectomy by thoracotomy. VATS lobectomy has not been widely adopted by the thoracic surgical community, in part, due to technical reasons. Pulmonary artery branch manipulation in VATS lobectomy is one of the most critical parts of the procedure, especially when endostaplers are used for ligation and division of the vessel...
