RESUMO

A syphilitic aortitis is a late cardiovascular lesion of tertiary syphilis that has become exceptionally rare in the antibiotic era but not eradicated completely. Syphilitic aortitis of ascending aorta complicates in ascending aortic aneurysm formation and aortic valve regurgitation, both requiring surgical treatment. After surgery, lifelong surveillance of the remainder of the aorta is recommended because of a priori supposed high incidence of delayed involvement of noninvolved aortic segments. A 3-year follow-up result of surgery of syphilitic ascending aortic aneurysm with aortic valve regurgitation in condition of active ongoing syphilitic aortitis and valvulitis is described with addressing the dimensions of remaining aortic segments. This case demonstrates that the dilatation of the remainder of the aorta does not occur during 3 years, at least when anti-syphilitic course of antibiotic is used just after operation without additional treatment during the follow-up period. A few reports on surgical treatment of syphilitic aneurysms of the ascending aorta are discussed.

RESUMO

INTRODUCTION: The native pulmonary valve (PV) reconstruction is an attractive alternative to a replacement but is challenging due to the systematic underdevelopment of the valve structures in congenital heart diseases. The partial replacement of underdeveloped parts of the valve and saving of well-developed may have advantages versus replacing the whole valve in terms of durability and patient outgrowth of the prosthesis. CASE PRESENTATION: This report describes a case of the PV reconstruction by allograft replacement of an underdeveloped anterior leaflet in an adolescent patient who previously corrected pulmonary stenosis during the first year of her life. The normal anatomy of the right and left leaflets was revealed. The rudimental anterior leaflet determined the annular restenosis. The monocusp with the related supporting aortic wall was sewn instead of the anterior leaflet. The Z-score of the pulmonary annulus changed from minus 3, 9 before to +0.8 after the procedure. The excellent function of the PV was observed in 1-year follow-up. DISCUSSION: Valve deterioration over time will have a less negative impact on the function when it occurs in a limited area. The annular dilatation becomes unlikely if the annulus predominantly consists of natural tissues. The procedural effectiveness allows the transcatheter valve-in-valve therapy in case of late dysfunction. The expected feature of the procedure described is that the growth of the PV remains possible. CONCLUSION: If allograft replacement of the PV is scheduled and allograft is available, the partial replacement may be superior to replacement of the whole valve in terms of durability and patient outgrowth of the prosthesis.

RESUMO

OBJECTIVES: Resection of a leiomyosarcoma of the inferior vena cava (IVC) requires venovenous bypass, especially if IVC clamping above the hepatic veins is planned. This report describes the application of external skin surface cooling for off-pump resection of a primary IVC leiomyosarcoma adjacent to the hepatic veins with graft IVC reconstruction in conditions of suprahepatic caval clamping and uninterrupted Pringle's manoeuvre. METHODS: A 62-year-old woman presented with IVC leiomyosarcoma adjacent to the hepatic veins. After anaesthesia induction, the patient's head, neck, abdomen, chest, thighs and shanks were covered by polyethylene bags containing granulated ice. The ice bag was also placed between the internal surfaces of the thighs. After 108 min, the target oesophageal temperature (29°C) was achieved, all bags were removed, except the bags that were used for temperature control during the operation located on head, neck and between internal surfaces of the thighs. Off-pump resection of the tumour was performed in conditions of suprahepatic IVC and portal triad clamping via median laparotomy. RESULTS: IVC clamping was accompanied by arterial hypotension of 55-65 mmHg well-tolerating in the hypothermic background for 69 min. The simultaneous application of an uninterrupted Pringle's manoeuvre was accompanied by low levels of transaminases and bilirubin. There was no local relapse of the tumour or metastases over a 6-month follow-up. CONCLUSIONS: External skin surface cooling in cases demanding IVC clamping above the hepatic veins and Pringle's manoeuvre allows avoiding venovenous bypass. This method is safe, cost effective, easily performed and may be used in clinical cases involving systemic arterial hypotension.
