Phân đoạn gan: chỉ định, kỹ thuật và định hướng tương lai
Tóm tắt
Đo thể tích gan đã trở thành một công cụ quan trọng trong thực hành lâm sàng. Thể tích gan được đánh giá chủ yếu thông qua phân đoạn các hình ảnh từ chụp cắt lớp vi tính (CT) và cộng hưởng từ (MRI). Mục tiêu của bài báo này là cung cấp một cái nhìn tổng quan dễ tiếp cận về phân đoạn gan nhằm vào các bác sĩ chẩn đoán hình ảnh và các chuyên gia y tế khác. Sử dụng hình ảnh từ CT và MRI, bài báo này xem xét các chỉ định cho việc phân đoạn gan, các phương pháp kỹ thuật được sử dụng trong phần mềm phân đoạn và vai trò đang phát triển của phân đoạn gan trong thực hành lâm sàng. Phân đoạn gan để đánh giá thể tích được chỉ định trước khi thực hiện phẫu thuật cắt gan lớn, tắc mạch tĩnh mạch cửa, phân chia gan liên kết và thắt tĩnh mạch cửa để phẫu thuật cắt gan theo giai đoạn (ALPPS) cùng với ghép gan. Phần mềm phân đoạn có thể được phân loại theo lượng đầu vào của người sử dụng: phân đoạn thủ công, bán tự động và hoàn toàn tự động. Phân đoạn thủ công được coi là "tiêu chuẩn vàng" trong thực hành lâm sàng và nghiên cứu, nhưng mất nhiều thời gian và công sức. Các phương pháp phân đoạn ngày càng tự động hóa mạnh mẽ hơn, nhưng cũng có thể gặp phải một số cạm bẫy trong phân đoạn. Những ứng dụng mới nổi của phân đoạn bao gồm lập kế hoạch phẫu thuật và tích hợp với các chỉ số sinh học dựa trên MRI. Phân đoạn gan có nhiều ứng dụng lâm sàng và đang mở rộng phạm vi. Các bác sĩ lâm sàng có thể sử dụng các tùy chọn phân đoạn bán tự động hoặc hoàn toàn tự động để tích hợp hiệu quả việc đo thể tích vào thực hành lâm sàng.
