BackgroundIn patients after aortic valve surgery, the quality of life is hypothesized to be influenced by the type of the valve procedure. A cross-sectional study on the postoperative quality of life was carried out in patients after aortic valve-sparing surgery (with regards to the age of the patient), Ross procedure and mechanical aortic valve replacement.MethodsQuality of life was studied in 139 patients after aortic valve surgery divided into four study groups (Y – aortic valve-sparing procedure at the age below 50 years, mean age 36.2 years; O – aortic valve-sparing procedure at the age 50 years and over, mean age 59.2 years; R – Ross procedure, mean age 37.8 years and M – mechanical aortic valve replacement at the age below 50 years, mean age 39.2 years). SF-36 Short Form and valve-specific questionnaires were mailed to the patients after 6 months or later following surgery (median 26.9 months).ResultsIn SF-36, the younger aortic valve repair patients and the Ross patients scored significantly better in 4 of 4 physical subscales and in 2 of 4 mental subscales than the older aortic valve repair and mechanical valve replacement patients. In the valve-specific questionnaire; however, all 3 groups free of anticoagulation (Y, O, and R) displayed greater freedom from negative valve-related concerns.ConclusionsPostoperative quality of life is influenced by the type of aortic valve procedure and is negatively linked with mechanical prosthesis implantation and long-term anticoagulation. Aortic valve-sparing strategy should be considered in cases with suitable valve morphology due to favorable clinical results and beneficial impact on the long-term quality of life.
We studied 44 patients undergoing carotid endarterectomy (CEA) to compare recovery after general anaesthesia with desflurane supplemented with either remifentanil or fentanyl. Remifentanil was infused at 0.1 microg kg(-1) min(-1) and desflurane was adjusted at 2 vol% end-tidal. Fentanyl was given as a bolus dose of 2 microg kg(-1) before induction and repeated at skin incision; desflurane was adjusted as needed. Times for early recovery and response to simple neurological tests (digit symbol substitution test (DSST) and Trieger dot test (TDT)) were measured 30, 60 and 90 min after operation. Emergence from remifentanil-desflurane anaesthesia was significantly quicker than that from fentanyl-desflurane anaesthesia: mean times to extubation were 4.1 (SD 1.7) and 8.2 (4.9) min, respectively; mean times for patients to state their name correctly were 6.0 (2.8) and 13.8 (9.0) min, respectively. Patients in the remifentanil-desflurane group successfully performed neurological tests significantly earlier than those in the fentanyl-desflurane group; for example, patients in the former group completed the arm holding test at 7.9 (3.0) min, while those in the latter group did this at 20.6 (19.7) min (P < or = 0.01). Intermediate recovery was less impaired at 30 min (DSST, TDT) and at 60 min (DSST). More rapid awakening and an earlier opportunity for neurological examination suggest that remifentanil-desflurane is a suitable alternative to a standard fentanyl-based general anaesthetic technique in patients undergoing CEA.
Lipoblastoma and lipoblastomatosis are rare benign neoplasms of foetal white fat tissue that occur almost exclusively in infants and children. Two cases are reported and a review of the literature is given. An almost one-year-old girl and a full-term male infant were brought to our hospital with a solid mass in the right thigh. Nine months after total excision of the lipoblastoma, the little girl developed tumour recurrence, with unexpected histopathological maturation. In the case of the little boy, lipoblastomatosis with infiltration of the surrounding muscles, together with involvement of the sciatic and posterior femoral cutaneous nerves was found. Histologically, the tumour showed an unusual inflammatory reaction. The diagnosis of this tumour was made by the pathologist, but the histopathological picture bears a striking similarity to myxoid liposarcoma, and may be indistinguishable. Recent studies describe rearrangements of chromosome 8 q11-q13 region as a new discriminative marker that distinguishes lipoblastoma and lipoblastomatosis from myxoid liposarcoma.
Surgical repair of postinfarction ventricular septal defect has a high 30-day mortality rate. Higher age at presentation and postoperative renal replacement therapy are independent predictors of early mortality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
