Dấu hiệu Buerger
Dấu hiệu Buerger là một công cụ không xâm lấn giúp đánh giá thiếu máu chi dưới
1 – Thực hiện
Dấu hiệu Buerger được đánh giá với hai giai đoạn. Trước tiên, bệnh nhân nằm ngửa, hai chân duỗi thẳng, người khám sẽ nâng và giữ chân bệnh nhân ở tư thế gập 45 độ trong 2 phút, quan sát thấy màu sắc da ở các ngón chân, mu và gan bàn chân của bệnh nhân sẽ chuyển từ hồng sang trắng bệch do thiếu máu. Giai đoạn hai, bệnh nhân ngồi buông hai chân xuống đất, cẳng chân tạo với mặt giường một góc 90 độ, màu da của bàn chân sẽ chầm chậm chuyển màu từ trắng sang xanh tím rồi đỏ bầm
2 – Cơ chế
Ở người khỏe mạnh, áp lực tưới máu cho chi dưới đủ lớn để giữ màu da luôn hồng ở mọi tư thế. Trong các bệnh lý làm giảm áp lực tưới máu cho bàn chân, khi chân được nâng ở tư thế gập 45 độ, áp lực này nhỏ hơn trọng lực, dòng máu tới bàn chân sẽ thiếu, bàn chân trở nên trắng bệch. Giai đoạn hai, khi buông hai chân xuống đất, bình thường bàn chân sẽ hồng ngay trở lại, nhưng khi áp lực tưới máu cho bàn chân giảm, thời gian tái tưới máu sẽ tăng lên. Màu da của bàn chân sẽ chậm hồng trở lại
3 – Giá trị của dấu hiệu
Dấu hiệu Buerger dương tính gợi ý sự thiếu máu chi dưới trầm trọng, cần can thiệp khẩn cấp. Trong trường hợp cung lượng tim bình thường, dấu hiệu Buerger chỉ điểm sự tổn thương các động mạch của chi dưới thường xảy ra trong các bệnh mạch máu ngoại biên
