Background Surgical management of aortic arch pathologies is complex, and endovascular developments have now enabled total or hybrid endovascular aortic arch repair. We present our early experience with fenestrated aortic arch repairs in Ishimaru zones 1 and 2 pathologies. Methods In a single tertiary institution, all consecutive endovascular aortic arch repairs were reviewed. A preoperative computed tomography aortogram was performed to assess anatomic suitability, which we defined as having a proximal sealing zone with a maximum diameter of 38 mm and minimum length of 20 mm, absence of significant aortic tortuosity, and suitable sealing zones in target vessels. Results From September 2015 to February 2018, 5 cases of fenestrated aortic arch endovascular repairs were performed. There were 3 male patients. The patients were between 57 and 83 years old, all of whom were American Society of Anesthesiologists (ASA) class II or III. Indications for surgery included aortic arch aneurysms (n = 3), a symptomatic aortic dissection, and a left subclavian artery aneurysm. Three patients had a scallop to the innominate artery, and one patient had a scallop to the left common carotid artery. Fenestrations were made to 3 left common carotid arteries and 3 left subclavian arteries. In 2 patients, a left carotid–subclavian bypass was performed, and the left subclavian artery origin occluded with a vascular plug. Technical success was 100%. One patient developed a right occipital infarct and acute myocardial infarction. The mean duration of surgery was 164 min, and the mean length of stay was 4.2 days. The mean follow-up period was 14.4 months. Conclusions The use of fenestrated grafts in the aortic arch is a feasible treatment option. However, certain limitations still exist, and preoperative planning is important in ensuring clinical success. Although this procedure appears feasible in the short term, long-term results and durability remain to be seen.

- Abstract
Purpose: To describe a case of extrinsic compression of the Ovation stent-graft following glue embolization for type II endoleak. Case Report: A 75-year-old man with a past history of ischemic heart disease and endovascular aneurysm repair with an Ovation stent-graft was admitted for treatment of type II endoleaks from the right L2 and left L4 lumbar arteries with egress via the inferior mesenteric and right L4 lumbar arteries, respectively. Successful embolization was performed via a translumbar sac puncture with a combination of coils and histoacryl glue. On final angiography severe lumen narrowing of the unsupported portion of the Ovation stent-graft was seen owing to extrinsic compression by the glue. This was successfully salvaged with percutaneous transarterial kissing balloon angioplasty. Conclusion: Aortic lumen narrowing caused by extrinsic compression of an Ovation stent-graft following glue embolization of type II endoleak is an unusual and potentially problematic complication.

Intestinal torsion and chylous ascites are very rarely associated. We present the case of a 19-year-old man who presented with acute abdomen. Computed tomography of his abdomen showed features suggestive of intestinal torsion. Chylous ascites was incidentally discovered on exploratory laparotomy. The chylous fluid was drained, the small bowel detorted and the coloduodenal adhesion band taken down. The patient's retroperitoneum was explored to exclude occult masses and malformations of the lymphatics. Post surgery, the patient recovered uneventfully. In this case, we postulate that intestinal malrotation had caused the obstruction of the lymphatic flow from the mesenteric lymphatic channels, leading to the exudation of chyle, which then resulted in the accumulation of chylous fluid in the peritoneal cavity. It is important to exclude the more common causes of atraumatic chylous ascites, such as enlarged retroperitoneal lymph nodes or lymphatic malformations.

Description of video: Background We present the case of a 75-year-old male patient with locally advanced Siewert Type 2 gastroesophageal adenocarcinoma post neoadjuvant chemotherapy. Inadvertent through-and-through piercing of the lower thoracic aorta with the tip of an energy device just above the diaphragm was sustained during the thoracoscopic esophageal dissection phase of the three-field minimally-invasive McKeown approach. Methods The procedure proceed thoracoscopically. The lower thoracic aorta was dissected and mobilized proximally and distally, and clamped on both ends with the introduction of Debakey clamps directly through separate small incisions in the chest wall. Primary repair of both anterior and posterior defects was then performed with monofilament non-absorbable sutures. Total clamp time was 30 minutes (in 15-minute intervals). Results Post-repair, perfusion status to the distal viscera and lower limbs were verified and intact. The rest of the operation then proceeded uneventfully. A Computed Tomography scan of the thoracic aorta on postoperative day 14 showed a patent thoracic aorta with no intraluminal narrowing or thrombosis. Conclusion Thoracoscopic repair of aortic injury sustained during the thoracoscopic dissection phase of a minimally invasive esophagectomy can be performed safely in well-selected, haemodynamically stable patients.
