An aberrant right subclavian artery (ARSA), arising from the proximal descending aorta, is a common aortic arch anomaly, with an incidence of 0.5% to 2%. However, coexistence of dissection and an ARSA is extremely rare. We presented the first case of successful management of complicated Stanford B-type aortic dissection combined with an ARSA with a new inclusion technique and stent graft (SG) implantation through an upper partial sternotomy. ⋯ This new inclusion technique through an upper partial sternotomy is a safe and feasible treatment for complicated Stanford B-type aortic dissection with an ARSA with the primary tear located in the aortic arch.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a disease with a poor prognosis, characterized by chronic thromboembolic obstruction of the pulmonary arteries and pulmonary hypertension. Balloon pulmonary angioplasty (BPA) is a newly emergent treatment for CTEPH, which may substitute pulmonary endarterectomy, the standard but more invasive treatment for CTEPH. Here, we report the case of a CTEPH patient who underwent 2 noncardiac surgeries without complications after preoperative intervention of BPA. ⋯ BPA can be an effective preoperative intervention for CTEPH patients undergoing noncardiac surgery.

Emergence agitation (EA) is common after nasal surgery. Strong opioids and N-methyl-D-aspartate (NMDA) receptor antagonists prevent EA. Tramadol also acts as an opioid receptor agonist and an NMDA receptor antagonist, but few studies have evaluated the effects of tramadol on EA. ⋯ Changes in systolic blood pressure in the 2 groups were similar, whereas changes in heart rate during emergence differed depending on the group (P = .020), although pairwise comparisons did not reveal any differences between the groups. Recovery time, postoperative pain scores, and adverse events were similar in the 2 groups. In adult patients undergoing nasal surgery, tramadol infusion decreases the incidence of EA after sevoflurane anesthesia without delaying recovery or increasing the number of adverse events.

Placenta previa accreta is an obstetrical complication that severely affects the heath of the fetus and the mother due to massive hemorrhage during pregnancy. This study reported a new suture technique called "cervical internal os plasty" to control obstetrical hemorrhage in cesarean delivery for patients with placenta previa accreta and retrospectively evaluated the safety and effectiveness of the new technique. From January 2012 to May 2018, we collected 56 patients with this new suture technique, which repaired the damaged weak area with bleeding from the placental attachment site in the lower uterine segment, and restored the damaged anatomic internal os of the cervix. ⋯ Compared with the control group, other applied supplementary techniques (including uterine tamponade, pelvic arterial embolization, or emergency hysterectomy) for the bleeding from the the placental attachment site is fewer significantly in the study group. No operative accident and hemorrhea-related complication occurred in the 2 groups. Cervical internal os plasty is useful in patients with placenta previa accreta due to its simplicity, utility, and effectivity as well as its capacity for preserving fertility.

Hydrochlorofluorocarbon 123 (HCFC-123, Freon123; 2,2-dichloro-1,1,1-trifluoroethane) has been widely used in refrigeration and heat-transfer applications as a substitute for chlorofluorocarbons due to its lower ozone-depleting potentials. Occupational exposure to HCFC-123 may cause mild reversible hepatoxicity, but no fatal cases have been reported yet. ⋯ The HCFC-123-induced hepatitis showed similarities with halothane hepatitis, both of which may share pathophysiologic mechanisms. Exposure to HCFC-123 needs to be listed as a potential cause of acute liver failure, and to be considered in patients with acute hepatitis of uncertain etiology and negative viral serology.
