arterial grafts

Hyungsub Park, Kwangmin Kim
The incidence of an isolated femoral vessel injury in the absence of fractures or other organ injury is extremely rare. A 20-yr-old male Korean soldier was taken to the hospital with a common femoral artery (CFA) obstruction. Injured CFA segment was resected and replaced by using 7-mm PTFE (polytetrafluoroethylene) graft. Two months after the surgical treatment, the patient discharged from the hospital without any complaints or postoperative complications. We report an unusual case of isolated femoral artery injury due to blunt trauma during military service with following review of literature...

Bioresorbable scaffolds (BRS) have been introduced to clinical practice to avoid some limitations associated with the presence of permanent metal prostheses in coronary arteries. Due to elimination of the natural vasomotion of the vessel and flow disturbance, stents impair endothelial function, increasing the risk of adverse events such as late and very late thrombosis or accelerated neoatherosclerosis. Additionally, the presence of metallic stents hinders non-invasive imaging of coronaries and may exclude the possibility of bypass graft anastomosis within the stented segment...

OBJECTIVES: Visceral arteries in fenestrated and branched endovascular repair (F/BEVAR) have been addressed by fenestrations or directional side branches. Inner branches, as used in the arch branched device, could provide an extra option for visceral arteries "unsuitable" for fenestrations or directional side branches. Early experience with the use of inner branches for visceral arteries in F/BEVAR is described. METHODS: All consecutive patients treated by F/BEVAR for complex abdominal aortic aneurysm (AAA) or thoraco-abdominal aneurysm (TAAA) using stent grafts with inner branches were included...

INTRODUCTION: Accurate dosing of protamine reversal following on-pump cardiac surgical procedures is challenging, with both excessive and inadequate administration recognised to increase bleeding risk. We aimed to examine the relationship between three ratios for heparin reversal and markers of haemostasis. METHODS: A retrospective analysis of a prospectively collected database was undertaken at a single tertiary cardiac unit, reviewing all cases of on-pump coronary artery bypass grafts and single valve replacements from 01/01/2011 to 31/12/2015...

BACKGROUND: Research into major bleeding during cardiac surgery is challenging due to variability in how it is scored. Two consensus-based clinical scores for major bleeding: the Universal definition of perioperative bleeding and the European Coronary Artery Bypass Graft (E-CABG) bleeding severity grade, were compared in this substudy of the Transfusion Avoidance in Cardiac Surgery (TACS) trial. METHODS: As part of TACS, 7,402 patients underwent cardiac surgery at 12 hospitals from 2014 to 2015...

BACKGROUND: Distal transradial access in the anatomical snuffbox has advantages over standard access in terms of patient and operator comfort levels and risk of ischemia. Radial artery preservation could be a relevant issue in patients requiring multiple radial artery procedures and coronary bypass with the use of a radial graft. One relevant drawback is the challenging puncture of a small and weak artery, with a steeper learning curve. AIM: The study was aimed at proving feasibility and safety of right and left transradial access in the anatomical snuffbox...

BACKGROUND: The contemporary use and outcomes of excimer laser coronary atherectomy (ELCA) in percutaneous coronary intervention (PCI) are not well described. METHODS: We examined the baseline clinical and angiographic characteristics and procedural outcomes of 130 target lesions in 121 consecutive PCIs (n = 116 patients) in which ELCA was performed at three United States Department of Veterans Affairs (VA) medical centers between 2008 and 2016. RESULTS: Mean age was 68...

OBJECTIVES: Rapid-deployment aortic valve replacement (RD-AVR) potentially reduces procedure times providing excellent haemodynamic results compared to standard tissue aortic valve replacement. However, concerns have been raised regarding higher rates of postoperative pacemaker (PPM) requirement compared to standard aortic valve replacement. In this study, we sought to determine the PPM rate and its potential risk factors in RD-AVR patients. METHODS: Between 2011 and 2017, 193 patients underwent RD-AVR...

We present a case of Kommerell's diverticulum with the aberrant left subclavian artery and a right-sided aortic arch in a 70-year-old male patient who was treated with total arch replacement using the Gelweave Lupiae graft. The Lupiae graft fitted well to total arch replacement for this pathology because the structure was consistent with the anatomical features.

BACKGROUND: The gut microbiota influences many immunological processes but how its disruption affects transplant rejection is poorly understood. METHODS: Interposition grafting of aortic segments was used to examine vascular rejection. The gut microbiota was disrupted in graft recipients using an antibiotic cocktail (ampicillin, vancomycin, metronidazole, neomycin sulfate) in their drinking water. RESULTS: Treatment of mice with antibiotics severely reduced total bacterial content in the intestine and disrupted the bacterial composition...

AIMS: Reconstruction of breasts and chest wall deformities in female patients after severe burn injury is a challenge for reconstructive surgeons. In these patients, neither implant-based procedures nor standard free flaps are sometimes applicable because of limited skin quality and unavailability of donor sites at the abdomen, back, buttock, or medial thigh. METHODS: We present a case of a young female patient with a history of 80 % total body surface area burn after electric high-voltage injury...

Despite being widely used for several years, the endovascular aortic repair (EVAR) of a thoracoabdominal aneurysm (TAAA) remains challenging, particularly the revascularization of the abdominal aortic visceral branches. A 66-year-old male was admitted to hospital with abdominal bloating and pain. Computed tomographic angiography (CTA) confirmed a Crawford type III TAAA from the distal descending aorta to the suprarenal abdominal aorta that involved the celiac axis, accompanied with an occlusion of the left subclavian artery...

BACKGROUND: Infants with a body weight of less than 10 kg are often not considered to be suitable candidates for renal transplantation (RTx). The objective of this study was to evaluate this arbitrary weight threshold for pediatric RTx. METHODS: We conducted a multicenter, retrospective, match-controlled cohort study on infants weighing less than 10 kg at time of engrafting (low-weight group [LWG], n = 38) compared to a matched control group (n = 76) with a body weight of 10-15 kg, using data from the first 2 years post-transplant derived from the CERTAIN Registry...
