Stigmata of recent bleeding evident, red wale signs present, and 1 white nipple sign identified in the anterior wall, in the same column coming from the middle esophagus. Successful variceal banding ligation was performed, and there was no recurrence of bleeding.Video 1The video shows the introduction of a calibrated, small-caliber-tip, transparent hood and its use in rectal, gastric, and duodenal endoscopic submucosal dissection with severe fibrosis.Video 1Combination of a dynamic rigidizing overtube and a novel injectable needle-type knife to facilitate colorectal endoscopic submucosal dissection.Video 1Demonstration of deploying a cardiac septal occluder for closure of a gastro-gastric fistula and the review of the literature regarding its use in managing GI fistulas.Video 1Use of submucosal injection prior to en-bloc endoscopic mucosal resection.Video 2Use of a detachable loop ligating device prior to hot snare resection of a pedunculated polyp.Lumbar spinal drain use during thoracic and thoracoabdominal aortic aneurysm repair has reduced the incidence of ischemic spinal cord injury with relatively low risk. We report a case of pneumocephalus in a 55-year-old woman who had undergone open repair of a 6.7-cm type IV thoracoabdominal aortic aneurysm. After lumbar spinal drain removal, she developed a postdural headache, which was subsequently treated with blood patch placement. After discharge, she had presented with transient headaches, perioral numbness, and left-hand weakness. Computed tomography revealed intraventricular gas within the lateral ventricles. Pneumocephalus is an exceedingly rare and potentially dangerous complication of lumbar spinal drains and blood patch placement.Infection of peripheral arterial vascular grafts and stent-grafts represents a complex surgical scenario, with a number of proposed management strategies. Surgical removal of infected material with adjunctive arterial reconstruction is often required. However, surgical removal is often difficult and complex. This case study demonstrates an infected Viabahn stent-graft between the external iliac artery and the superficial femoral artery, with arterial autolysis of the common femoral artery and proximal superficial femoral artery, in which a hybrid technique combining remote endarterectomy and surgical debridement was used to remove the infected stent-graft.We have reported a case of delayed hip prosthetic erosion into the common femoral artery (CFA) 3 years after implantation. The patient had initially presented with left lower extremity acute limb ischemia secondary to a popliteal artery embolism. However, the metal artifact around the hip joint prevented CFA evaluation using conventional imaging. Diagnostic angiography with intraoperative intravascular ultrasound revealed CFA dilatation with adherent intraluminal thrombus. Open surgical repair showed hip prosthesis erosion through the posterior wall of the CFA. Our findings emphasize the necessity for a thorough, multimodal embolic workup and the usefulness of intravascular ultrasound as an adjunctive tool for intravascular anatomy evaluation.Hybrid approaches for the treatment of thoracoabdominal aortic aneurysms that combine visceral debranching and endovascular repair are feasible alternatives to open surgery for certain high-risk patients. A 70-year-old man was admitted with a rapidly expanding thoracoabdominal aneurysm involving the superior mesenteric artery, associated with an aberrant hepatic artery. An iliovisceral debranching was performed, followed by the endovascular repair of the thoracoabdominal aorta with a standard thoracic device. The ostial aneurysm was excluded by retrograde implantation of a covered stent from the superior mesenteric artery. Such approach can be considered as a viable alternative in the management of complex thoracoabdominal aneurysms.The use of a Viabahn VBX endoprosthesis (W. L. https://www.selleckchem.com/products/melk-8a-hydrochloride.html Gore & Associates, Flagstaff, Ariz) to exclude chronically thrombosed inferior vena cava (IVC) filters refractory to exclusion with self-expanding stents was evaluated. The mean duration of TrapEase IVC (Cordis, Milpitas, Calif) implantation was 7.6 years (range, 2-11 years). Symptoms included leg pain, edema, color changes, and back pain. The mean Villalta score and venous clinical severity score were 17 (range, 13-23) and 13 (range, 11-15), respectively. Indirect ultrasound evidence of stent patency was demonstrated at a mean of 8 months after intervention. The mean Villalta score and venous clinical severity score had decreased by 13 and 10, respectively, at a mean of 9.5 months after intervention. Iliocaval reconstruction with Viabahn VBX balloon expandable stent-graft exclusion of chronically thrombosed TrapEase IVC filters is safe, with favorable short-term results.A severely compromised left ventricular ejection fraction (LVEF) is a major limitation for lower extremity bypass reconstruction both under general anesthesia or neuraxial anesthesia (NA). A series of eight infrainguinal bypass procedures were performed under peripheral nerve block in five patients (three males and two females; median age, 67 years) with chronic limb-threatening ischemia and a preoperative LVEF of 35% or less (median, 27%; range, 20%-35%). There were no conversions to neuraxial anesthesia/general anesthesia or early postoperative complications. This study showed that open infrainguinal reconstructions can be performed safely under peripheral nerve blockade in this vulnerable category of patients.
