THROMBOSIS OF THE ABDOMINAL AORTA (FIGures 92-1 TO 92-6)

FIGURE 92-1

Sequential axial contrast-enhanced CT images of a candidate being evaluated for transplantation. Proximally there is a patent enhancing upper abdominal aorta (yellow arrow).

A radiograph of a patient highlights the upper abdominal aorta. The radiograph of a patient shows the upper abdominal aorta evaluated for transplantation. A white circular ball is visible on the upper abdominal aorta, the bottom center portion indicated by a down arrow.

FIGURE 92-2

Sequential images show thrombosis of the midportion of the aorta (red arrow).

A radiograph depicts the thrombosis of the midpoint portion of the aorta. The radiograph shows thrombosis, the formation of a blood clot on the bottom center of the aorta, within the white ball.

Sequential images show thrombosis of the midportion of the aorta (red arrow).

A radiograph of a patient for thrombosis in the aorta. The radiograph of a patient shows the upper abdominal aorta evaluated for transplantation. A circular ball with a thick white border is visible on the midportion of the aorta, at the bottom center and is indicated by a down arrow.

FIGURE 92-4

The distal aorta and external iliac arteries are not patent.

A radiograph depicts the not patent portion of the distal aorta and external iliac. The distal aorta at the bottom center and the external iliac arteries that resemble white and earth-worm like on the top center are not closed and remain open.

FIGURE 92-5

The prominent inferior epigastric arteries as well as the multiple collaterals throughout the body reflect collateralization of flow. Notice the multiple acquired cysts in both native kidneys, some of them hyperattenuating due to hemorrhagic changes (of concern for malignancies).

A radiograph depicts the collateralization flow reflected throughout the body with multiple collaterals in the prominent inferior arteries. The radiograph shows irregularly-shaped multiple cysts spread throughout both the kidneys due to the leakage of blood from a ruptured blood vessel.

RENAL PATHOLOGIES (FIGURES 92-7 TO 92-10)

FIGURE 92-7

Pretransplant evaluation computed tomography image that shows a hyperattenuating lesion that could, on an unenhanced scan, represent either a hyperdense cyst (Bosniak 2) or a solid mass. This lesion exhibited a brisk enhancement suggesting a small renal cell carcinoma as was subsequently proven by microscopic tissue examination in the right kidney. All suspicious lesions should be thoroughly evaluated to exclude malignancies.

A radiograph depicts the pretransplant evaluation. The radiograph shows the unenhanced scan in the hyperattenuating session forming a hyperdense cyst as a solid mass. In the right kidney, a small renal cell carcinoma is shown in the microscopic tissue examination. The malignancies are excluded is evaluated by all suspicious lesions.

FIGURE 92-8

Pretransplant evaluation computed tomography showing atrophic native kidneys (red arrows). Note the splenomegaly (S).

A radiograph depicts arrows pointing to the pretransplant evaluation in both atrophic kidneys. The radiograph is taken during pre-transplant and confirms atrophy or decrease in size of both the kidneys indicated by arrows. Also, an enlargement of the spleen (s) in the vertical direction along the right side is seen.

FIGURE 92-10

Longitudinal ultrasound image of a small native kidney (white arrow) showing loss of corticomedullary differentiation, typical of end-stage kidney disease (small native kidney encircled by asterisks).

An arrow pointing to the small kidney encircled by asterisks shows loss of corticomedullary differentiation and typical end-stage kidney disease.

RENAL CELL CARCINOMA OF THE NATIVE KIDNEYS (FIGURES 92-11 AND 92-12)

FIGURE 92-11

Axial contrast-enhanced computed tomography image showing a rounded, heterogeneously enhancing mass (green arrow) emerging from the posterior aspect of the atrophic right native kidney. This is a typical appearance of a renal cell carcinoma. Patients on long-term dialysis treatment are more susceptible to the development of diverse lesions, among which ...
