Successful use of methylene blue for catecholamine-refractory vasoplegic shock due to metformin intoxication: A case report and literature review.

Background: Severe metformin intoxication can lead to lactic acidosis and vasoplegic shock, for which the optimal management strategy remains uncertain, especially in cases of severe circulatory collapse.

Case Presentation: A 45-year-old diabetic woman on metformin therapy presented with impaired consciousness and seizures. She had experienced a cardiac arrest and undergone extracorporeal cardiopulmonary resuscitation.

Tiger prowling: Distribution modelling for northward-expanding Aedes albopictus (Diptera: Culicidae) in Japan.

The Asian tiger mosquito, Aedes albopictus, is a significant public health concern owing to its expanding habitat and vector competence. Disease outbreaks attributed to this species have been reported in areas under its invasion, and its northward expansion in Japan has caused concern because of the potential for dengue virus infection in newly populated areas. Accurate prediction of Ae.

Outcomes of Clampless Real Chimney Technique with Dacron Graft and Sleeve Banding of the Ascending Aorta for Total Debranching Endovascular Arch Repair.

Background: Hybrid aortic arch repair with debranching of the supra-aortic vessels carries a high risk of cerebral infarction and fatal complications associated with side clamping of the ascending aorta. A previous study had reported the "real chimney" technique, a novel method for clamp-free total debranching thoracic endovascular aortic repair with the ascending aortic sleeve banding with dacron. In this study, we aim to build upon this foundation by presenting our experience with the early and midterm outcomes of this technique.

Midterm outcomes of side branch embolization and endovascular abdominal aortic aneurysm repair.

Objective: To analyze the effects of total side branch embolization at endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms on the incidences of persistent type 2 endoleak (pT2EL), changes in sac diameter, and reintervention.

Methods: Between 2013 and 2021, all patients who underwent primary EVAR with a few exceptions were included. Side branch embolization was considered during EVAR for inferior mesenteric artery (IMA) or IMA plus lumbar artery (LA) when feasible for contrast agent use.

Modified adaption of iliac branch endografts in rare congenital anomaly of proximal origin of bilateral internal iliac arteries.

We report a case of 55 mm abdominal aortic aneurysm coinciding with a rare congenital anomaly of proximal origin of bilateral internal iliac arteries (IIAs). Because renal to iliac bifurcation lengths were bilaterally short (129 mm and 125 mm), a trunk-ipsilateral leg and an iliac leg were deployed before iliac branch component insertion into the iliac leg. With help of a pull-through wire, internal iliac component was delivered without migration of the main body.
