Ross operatsiyasining bolalarda tug‘ma aortal qopqoq patologiyasidagi qo‘llanilishi
Annotatsiya
Maqsad. Tug‘ma aortal qopqoq stenoz yoki etishmovchiligi bo‘lgan bolalarda Ross operatsiyasining klinik samaradorligi va xavfsizligini baholash. Tadqiqotning asosiy maqsadi Ross usulining an’anaviy protezlash operatsiyalariga nisbatan fiziologik va gemodinamik afzalliklarini aniqlashdan iborat.
Materiallar va usullar. Medion Innovation markazida 2022–2025 yillar davomida Ross operatsiyasi o‘tkazilgan 14 nafar bemorning klinik ma’lumotlari tahlil qilindi. Asosiy tashxislar aortal stenoz (n=9) va aortal etishmovchilik (n=5) bo‘lib, barcha holatlarda to‘liq aorta ildizini almashtirish texnikasi (full root replacement) qo‘llanildi. Operatsiyadan keyingi echokardiyografik ko‘rsatkichlar, jumladan aortal bosim gradienti va regurgitatsiya darajasi baholandi.
Natijalar. Operatsiyadan keyingi davrda barcha bemorlarda gemodinamik ko‘rsatkichlarning sezilarli darajada yaxshilanishi kuzatildi. O‘rtacha aortal bosim gradienti 45 ± 12 mm sim.ust.dan 8 ± 3 mm sim.ust.gacha kamaydi, va klinik ahamiyatga ega regurgitatsiya holatlari qayd etilmadi. Hech bir bemorda erta operatsiyadan keyingi asoratlar yoki avtoimplant disfunktsiyasi aniqlanmadi.
Xulosa. Ross operatsiyasi bolalarda tug‘ma aortal qopqoq patologiyalarini davolashda samarali va xavfsiz usul bo‘lib, u fiziologik gemodinamikani tiklaydi, uzoq muddatli prognozni yaxshilaydi va qayta operatsiya ehtiyojini kamaytiradi. Tadqiqot natijalari ushbu usulni bolalar kardiokirurgiyasi amaliyotida kengroq qo‘llash maqsadga muvofiqligini tasdiqlaydi.
