Venous compression site identification and stent deployment guidance, and associated devices, systems, and methods

A system includes a processor circuit configured to communicate with an external imaging device. The processor circuit receives, from the external imaging device, an image including a blood vessel within a patient. The processor circuit uses the image to determine a first location in the blood vessel having a blood flow restriction caused by compression of the blood vessel by an anatomical structure different from the blood vessel in the patient. The processor circuit generates a first graphical representation associated with the restriction. The processor circuit outputs a screen display to a display in communication with the processor circuit. The screen display includes the image and the first graphical representation at the first location of the blood vessel in the image. 一种系统包括被配置用于与外部成像设备通信的处理器电路。所述处理器电路从所述外部成像设备接收包括患者体内的血管的图像。所述处理器电路使用所述图像来确定所述血管中具有血流受限的第一位置，所述血流受限是由所述患者体内的不同于所述血管的解剖结构对所述血管的压迫引起的。所述处理器电路生成与所述受限相关联的第一图形表示。所述处理器电路向与所述处理器电路通信的显示器输出屏幕显示。所述屏幕显示包括所述图像以及在所述图像中的所述血管的所述第一位置处的所述第一图形表示。
