What is an early sonographic appearance of renal transplant rejection?

The sonographic changes in rejected kidneys were compared to those in 21 normal allografts. We found that renal enlargement, enlarged medullary pyramids, and a reduction in or a disappearance of the sinus echos were seen in acute rejection but were not seen in normal renal transplants.

What is the most common vascular complication of renal transplant?

Transplant renal artery stenosis (TRAS) is the most common vascular complication following renal transplantation. Depending upon the criteria used for diagnosis its incidence varies from 1 to 23%. 4 TRAS is a potentially curable cause of treatment refractory hypertension and graft dysfunction.

Are blood clots common after kidney transplant?

Blood clots This is estimated to occur in around 1 in 100 kidney transplants. In some cases, it may be possible to dissolve the blood clots using medication, but it’s often necessary to remove the donated kidney if the blood supply is blocked.

How would you determine stenosis in a transplanted kidney?

Duplex sonography is the most commonly used screening tool, whereas angiography provides the definitive diagnosis. Percutaneous transluminal angioplasty with stent placement can be performed during angiography if a lesion is identified, and it is generally the first-line therapy for TRAS.

What is the most common post-transplant complication?

Acute rejection — is the most common kind and develops over a short period of time, a few days or weeks. The risk is highest during the first 2 to 3 months, but can also happen a year or more after transplant.

How often do vascular complications post-transplant surgery occur?

Although vascular complications account for only 5–10 % of all post-transplant complications, they are a frequent cause of graft loss.

Are transplant patients more prone to blood clots?

Earlier studies have documented an increased risk of thromboembolic events (TEs) after kidney transplantation (KT). Although in the first months after transplantation the risk of TE can be related to the transplant surgery, there seems to be an increased long-term TE risk in kidney transplant recipients (KTRs).

What are the symptoms of kidney transplant rejection?

Signs and Symptoms of Acute Rejection

• Tenderness or pain over the kidney transplant.
• A general achy feeling.
• Swelling in the hands and feet.
• An elevated temperature.
• A rapid weight gain.
• An increase in blood pressure.
