Summary
Portal vein thrombosis after liver transplant can cause graft failure. Direct superior mesenteric vein (SMV) access by interventional radiology (IR) and surgery teams successfully removed thrombus, preserving the graft.
Area of Science:
- Interventional Radiology
- Transplant Surgery
- Hepatology
Background:
- Portal venous thrombosis and stenosis are critical complications impacting liver transplant graft survival.
- While surgical options exist, interventional radiology (IR) offers promising venous interventions.
Observation:
- A 69-year-old female with non-alcoholic steatohepatitis cirrhosis developed portal vein thrombus post-liver transplant.
- Collaboration between transplant surgery and IR was crucial for managing this complication.
Findings:
- Successful thrombus removal was achieved through direct superior mesenteric vein (SMV) access.
- This approach facilitated a direct route to the thrombus, minimized damage to liver parenchyma, and ensured effective hemostasis.
Implications:
- Direct SMV access presents a valuable strategy for managing post-transplant portal vein thrombus.
- This minimally invasive technique enhances graft survival and patient outcomes in liver transplantation.

173
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration.

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...
