Redo aortic valve replacement versus valve-in-valve trans-catheter aortic valve implantation: a UK propensity-matched analysis.

This study sought to compare the morbidity and mortality of redo aortic valve replacement (redo-AVR) versus valve-in-valve trans-catheter aortic valve implantation (valve-in-valve TAVI) for patients with a failing bioprosthetic valve. A multicenter UK retrospective study of redo-AVR or valve-in-valve TAVI for patients referred for redo aortic valve intervention due to a degenerated aortic bioprosthesis. Propensity score matching was performed for confounding factors. From July 2005 to April 2021, 911 patients underwent redo-AVR and 411 patients underwent valve-in-valve TAVI. There were 125 pairs for analysis after propensity score matching. The mean age was 75.2±8.5 years. In-hospital mortality was 7.2% (n=9) for redo-AVR versus 0 for valve-in-valve TAVI, p=0.002. Surgical patients suffered more post-operative complications, including intra-aortic balloon pump support (p=0.02), early re-operation (p<0.001), arrhythmias (p<0.001), respiratory and neurological complications (p=0.02 and p=0.03) and multi-organ failure (p=0.01). The valve-in-valve TAVI group had a shorter intensive care unit and hospital stay (p<0.001 for both). However, moderate aortic regurgitation at discharge and higher post-procedural gradients were more common after valve-in-valve TAVI (p<0.001 for both). Survival probabilities in patients who were successfully discharged from the hospital were similar after valve-in-valve TAVI and redo-AVR over the 6-year follow-up (log-rank p=0.26). In elderly patients with a degenerated aortic bioprosthesis, valve-in-valve TAVI provides better early outcomes as opposed to redo-AVR, although there was no difference in mid-term survival in patients successfully discharged from the hospital.

True superior gluteal artery aneurysm with neurovascular compromise of the lower limb: a case report and review of the therapeutic options.

Few cases of true superior gluteal artery (SGA) aneurysms have been described in the English-language literature. This is the twenty-second reported case. SGA aneurysms can pose diagnostic problems, specifically when they are non-pulsatile and also therapeutic challenges when they are large. Although more aneurysms are being subjected to endovascular therapies, SGA aneurysmectomy or aneurysmorrhaphy still remain valid therapeutic options, especially in resource-poor settings. Surgery provides quick symptom resolution and still is the only means by which tissue for definitive histological diagnosis can be obtained.

Refractory bleeding from a giant de-differentiated liposarcoma of the chest wall: An indication for neoadjuvant chemotherapy and palliative resection? - A case report.

INTRODUCTION: Dedifferentiated liposarcoma (DDLPS) is a heterogenous neoplasm of variable histological grade. DDLPS uncommonly arises from the chest wall. There are limited data available about the tumor's response to chemotherapy and accessible reports indicate minimal benefits. Surgery is thus the cornerstone of management. Here, we demonstrate an uncommon situation where chemotherapy was used to arrest bleeding from a giant DDLPS that was refractory to all available hemostatic agents. This case also presents an uncommon indication for palliative chest wall resection and reconstruction (CWRR). PRESENTATION OF CASE: A 55-year old woman presented with refractory bleeding from an ulcerated and foul-smelling mass on the anterior chest wall, confirmed histologically to be DDLPS. Chemotherapy with Doxorubicin and Ifosfamide was used to control the bleeding. She subsequently had CWRR to improve her quality of life. The patient made an uneventful recovery but later died from pulmonary embolism. DISCUSSION: The dedifferentiated component of DDLPS is vascular and may account for why we were able to exhibit a hemostatic response to chemotherapy. CWRR was then employed to improve the quality of life in an advanced, ulcerated and infected tumor of the chest wall. CONCLUSION: We were able to demonstrate a hemostatic response of DDLPS to neoadjuvant chemotherapy and anticipate that this report may serve as a reference for further studies. Furthermore, we believe that palliative resection may be carried out to improve a patient's quality of life even in the face of advanced disease.

A descriptive study of commonly used postoperative approaches to pediatric stoma care in a developing country.

Construction of an enterostomy is a common procedure in pediatric surgery. However, caring for the child with a stoma is challenging for parents in developing countries. Modern devices such as colostomy bags and accessories are expensive and not readily available. The purpose of this study was to describe methods of effluent collection and peristomal skin protection used by the mothers of colostomy patients. A prospective, descriptive study was conducted between January and December 2011 during the first three postoperative outpatient clinic visits among mothers of children who had a colostomy constructed in the authors' hospital. The mothers of 44 children (27 males, 17 females, median age 3.3 months, range 2 days to 11 years) consented to participate. Demographic and clinical data were obtained from the records, and mothers were interviewed and asked to describe their preferred methods of colostomy effluent collection and peristomal skin protection. The stomas also were inspected at each clinic visit. Anorectal malformations were the most common indication for a colostomy (32, 72.73%), followed by Hirschsprung's disease (11, 25%). Forty-two (42) patients had a divided sigmoid colostomy (95.45%); two patients had a right loop transverse colostomy (4.55%). Nine mothers alternated between two different collection methods. The diaper collection method was described most frequently (22 out of 53; 41.51%), followed by wraparound waistbands (19; 35.85%) and improvised colostomy bags (12; 22.64%). Peristomal skin excoriations were commonly seen within the first 3 weeks postsurgery and had mostly disappeared by the week 6 postoperative visit. Petrolatum jelly was the most commonly used barrier ointment. These locally available, acceptable, and affordable collection methods may be useful for children in other developing countries.
