Endovascular redo aortic operations are a challenging undertaking. Techniques for treatment date almost as far back as the original open repair itself. Risk factors for failure following aortic repair include larger AAA necks, severe neck angulation, as well as clinical variables such as age, family history, obesity and chronic obstructive pulmonary disease. The armamentarium of endovascular treatments is vast and increasing. Aside from provisional embolization of endoleaks or deferment to open repair conversion, attention should be directed toward obtaining adequate proximal and distal sealing...

Hemostasis is the process of sealing a vascular injury with a thrombus to arrest bleeding. The type of thrombus that forms depends on the nature of the injury and hemodynamics. There are many models of intravascular thrombus formation whereby blood is exposed to prothrombotic molecules on a solid substrate. However, there are few models of extravascular thrombus formation whereby blood escapes into the extravascular space through a hole in the vessel wall. Here, we describe a microfluidic model of hemostasis that includes vascular, vessel wall, and extravascular compartments...

Acute aortic dissection is a rare but devastating complication during cardiac catheterization. We present the case of an elderly female who incurred a Stanford Type A/DeBakey Type I acute aortic dissection extending into the arch vessels and descending aorta likely occurring during right coronary artery engagement for angioplasty. The patient was treated successfully by immediately sealing the entrance of the dissection via the placement of a stent and anti-impulse therapy. Follow-up computed tomography scan showed complete resolution of the dissection within one month...

BACKGROUND: Botulinum toxin-A (BTX) has numerous cosmetic and therapeutic applications. Our previous studies have found that BTX augments pedicled flap survival through both vasodilatory effects and attenuation of the inflammatory response to ischemia in the rat. This study examines the effect of chronic BTX on microcirculatory vascular tone and its response to acute topical vasodilators in muscle flaps. METHODS: The spinotrapezius muscle of Sprague-Dawley rats underwent a single 2-week pretreatment of 0...

Nowadays laparoscopic approach is accepted as a valid alternative to open surgery for the treatment of colorectal cancer. Several studies consider this approach to be safe and feasible also in obese patients, even if dissection in these patients may require a longer operative time and involve higher blood loss. To facilitate laparoscopic approach, more difficult in these patients, several energy sources for laparoscopic dissection and sealing, has been adopted recently. The aim of this study is to investigate the possible intraoperative advantages of radiofrequency energy in terms of blood loss and operative time in obese patients undergoing laparoscopic resection for cancer...

Long microchannels with thin walls, small width, and nanoholes or irregular shaped microgaps, which are similar to capillaries or cancerous vessels, are urgently needed to simulate the physiological activities in human body. However, the fabrication of such channels remains challenging. Here, microchannels with designable holes are manufactured by combining laser printing with line-contact capillary-force assembly. Two microwalls are first printed by femtosecond laser direct-writing, and subsequently driven to collapse into a channel by the capillary force that arises in the evaporation of developer...

Our treatment strategy for acute type B aortic dissection (ABAD) included complicated type is as follows. Indications of thoracic endovascular aortic repair (TEVAR) for ABAD are rupture and organ ischemia, and TEVAR has been the 1st line central repair therapy since January 2009 in our institution. At the time of TEVAR for ruptured communicating type ABAD, we usually seal the proximal entry tear and cover the existing range of hematoma at descending aorta. Procedures for ABAD with malperfusion should be changed according to the patient's condition such as branch vessel obstructions either dynamic type or static type...

A 77-year-old male patient presented with a symptomatic, 66-mm pararenal aortic aneurysm. The patient was classified as unsuitable for open surgery due to significant comorbidities. Fenestrated or branched endografts were contraindicated due to the poor iliac access (6 mm diameter). A double Nellix with chimney endovascular aneurysm sealing (ChEVAS) technique was selected to exclude the pararenal aortic aneurysm and to preserve renal arteries and the superior mesenteric artery. Technical preplanning considered the ideal proximal landing zone to be close to the origin of the almost occluded celiac trunk and the distal common iliac arteries as the ideal distal landing zone...

INTRODUCTION: Upper gastrointestinal bleeding (UGIB) is the key emergency situation in clinical endoscopy and is traditionally treated with injection, thermal or through the scope clipping therapy. Mortality rates are in the range of 8-10% and demand new treatment approaches. The Over-The-Scope Clip (OTSC(®)) has been described as a very effective hemostatic device in UGIB. We compared OTSC with the Padlock™ device in an established pre-clinical setting. MATERIAL AND METHODS: Our test-bed consisted of the biohybrid EASIE model using soft silicone tubes, tunneled into the gastric wall and surfacing at a mucosa defect, representing the bleeding site...

INTRODUCTION: The electrothermal bipolar vessel-sealing device (BVSD) is known to supply a strong vessel-sealing power. However, only few studies have reported lymph node dissection (LND) using only BVSD during laparoscopic surgery for gastric cancer. The purpose of this study was to investigate the feasibility of LND using BVSD during reduced port laparoscopic distal gastrectomy for gastric cancer. METHODS: From May 2015, patients in whom three- or single-port laparoscopic distal gastrectomy had been engaged for gastric cancer were enrolled in this study...

Blood-central nervous system (CNS) barriers partition neural tissues from the blood, providing a homeostatic environment for proper neural function. The endothelial cells that form blood-CNS barriers have specialized tight junctions and low rates of transcytosis to limit the flux of substances between blood and CNS. However, the relative contributions of these properties to CNS barrier permeability are unknown. Here, by studying functional blood-retinal barrier (BRB) formation in mice, we found that immature vessel leakage occurs entirely through transcytosis, as specialized tight junctions are functional as early as vessel entry into the CNS...
