Objective: To compare the outcomes between total arch replacement (TAR) and nontotal arch replacement (non-TAR) in patients with acute type A aortic dissection (ATAAD).
Methods: Between 2006 and 2018, 275 ATAAD patients were divided into 2 groups, the TAR group ( = 63) and the non-TAR group ( = 212), and multiple variables were analyzed.
Results: The TAR patients were older than the non-TAR patients (61.5 ± 11.8 vs. 57.4 ± 14.5 years, = 0.024). The TAR group had longer operative, cardiopulmonary bypass, aortic clamping, and circulatory arrest times than the non-TAR group (all < 0.001). The overall hospital mortality rate was 8.7% with no statistically significant difference between the TAR and non-TAR groups (9.5% vs. 8.5%, = 0.799). There was no significant difference in the incidence of acute kidney injury (AKI), intubation time, incidence of postoperative atrial fibrillation (AF), or reoperation for bleeding or reintervention rates between the TAR and non-TAR groups (68.3% vs. 65.7% ( = 0.912), 44.8% vs. 33.8% ( = 0.127), 30.2% vs. 22.6% ( = 0.222), 9.5% vs. 9.5% ( = 0.189), and 7.9% vs. 7.1% ( = 0.077), respectively). The TAR group had a higher rate of new permanent neurological deficit (PND) than the non-TAR group and longer median length of hospital stay (17.5% vs. 6.1% ( < 0.001) and 9 vs. 12 days ( = 0.049), respectively). TAR (relative risk (RR) 3.66, = 0.005) and preoperative cardiopulmonary resuscitation (CPR) (RR 6.60, = 0.019) were risk factors of PND. Survival rate was similar between the two groups.
Conclusion: The mortality rates in ATAAD patients with TAR and non-TAR were similar. However, the incidence of new permanent postoperative neurological deficit was significantly higher, and the length of hospital stay was longer in patients with TAR. TAR in ATAAD should be avoided especially in patients who have experienced preoperative CPR to abate risk of PND.

: In the presence of porcelain aorta (PA), transcatheter aortic valve replacement (TAVR) has become a class I therapeutic indication for the treatment of severe aortic valve stenosis. To date, few studies have analyzed the clinical outcomes of TAVR in PA patients. We aim to analyze the calcification patterns of the thoracic aorta in PA patients and to evaluate their clinical implications for TAVR procedures.

Purpose: Dexamethasone has shown promising efficacy in alleviating pain and enhancing outcomes undergoing TKA. However, an optimal route of administration, dosage, and treatment duration have not yet been established. This study is to assess the effects of intravenous dexamethasone administration on postoperative pain management and prognosis in patients undergoing TKA.

Female sexual dysfunction is highly prevalent among postmenopausal females approaching 50%, with vulvovaginal atrophy (VVA) being a cardinal sign. For decades, hormone replacement therapy was the only solution to relieve symptoms associated with this atrophy. However, it was limited by its serious side effects, raising the need for new treatment strategies.

Introduction: Patients undergoing total hip arthroplasty (THA) with preoperative anemia are at higher risk for transfusion. Blood-conserving interventions can reduce perioperative transfusions. This retrospective study evaluates the efficacy and safety of a patient blood management (PBM) protocol in elective primary THA patients with preoperative anemia.

Objectives: Acute type A aortic dissection (ATAAD) is a life-threatening condition that requires emergent surgical intervention. Numerous surgical approaches exist for ATAAD, and controversy remains regarding the optimal arch interventions for ATAAD patients. Aortic Arch Interventions: Approaches to ATAAD repair include hemiarch repair or extended arch repairs, including the hemiarch with a hybrid stent implantation, such as the AMDS hybrid Prosthesis, total arch replacement (TAR), and the use of an elephant trunk and frozen elephant trunk.
