Insights

Hepatic artery stenosis (HAS) after liver transplant is serious but treatable. Balloon angioplasty can cause major complications, sometimes needing surgery, impacting graft survival.

Area of Science:

  • Hepatology
  • Transplant Surgery
  • Vascular Interventions

Background:

  • Hepatic artery stenosis (HAS) is a rare but serious liver transplant complication.
  • Untreated HAS can lead to hepatic artery thrombosis, biliary necrosis, and graft loss.

Purpose of the Study:

  • To present two cases of hepatic artery stenosis treated with balloon angioplasty.
  • To highlight major complications arising from this endovascular treatment.

Main Methods:

  • Diagnosis of HAS using Doppler ultrasound, CT angiography, and MR angiography.
  • Endovascular treatment involving balloon angioplasty +/- stent placement.

Main Results:

  • Balloon angioplasty led to major complications in both presented cases.
  • These complications necessitated further operative intervention.

Conclusions:

  • While endovascular treatment for HAS is generally safe and effective, major complications can occur.
  • Such complications can significantly jeopardize long-term liver graft survival, requiring surgical management.

Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors01:28

Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors

Phosphodiesterase 5 (PDE5) inhibitors are potent enzymes that function to hydrolyze cyclic nucleotides to their corresponding 5' monophosphates. Their unique biochemical properties have been applied in treating Pulmonary Arterial Hypertension (PAH).
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...

Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists

Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...
