Insights

Transsplenic portal venous access is safe and effective for pediatric diagnostic imaging and interventions when other methods fail. Minimizing access size reduces bleeding risks, making this approach valuable for complex cases.

Area of Science:

  • Pediatric Interventional Radiology
  • Hepatobiliary Surgery
  • Vascular Access Techniques

Background:

  • Limited data exists on transsplenic portal venous access in children.
  • Concerns about bleeding risks have led to underutilization of this technique.
  • Transsplenic access may be crucial for specific diagnostic and interventional procedures.

Purpose of the Study:

  • To evaluate the safety and efficacy of transsplenic splenoportography in children.
  • To assess the utility of transsplenic portal venous interventions in pediatric patients.
  • To determine the factors influencing the success and complications of transsplenic access.

Main Methods:

  • Retrospective review of pediatric patients undergoing percutaneous transsplenic portal venous access.
  • Analysis of procedural indications, imaging, technical details, and clinical outcomes.
  • Data collected from two tertiary pediatric institutions between 2012 and 2017.

Main Results:

  • Transsplenic portal venous access was successful in all cases.
  • Diagnostic splenoportography achieved 100% success in providing necessary information.
  • Four complex portal interventions, including angioplasty and thrombectomy, were 100% successful.
  • Intraperitoneal bleeding occurred in 7.7% of cases, with transfusion needed in 3.8%.
  • No hemorrhage was observed with 4 Fr or smaller access tracts.

Conclusions:

  • Transsplenic splenoportography is safe and effective for pediatric patients when noninvasive imaging is insufficient.
  • The transsplenic approach offers advantages for complex portal venous interventions.
  • Bleeding risk is associated with access tract size and can be managed with embolization.

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Hepatic Portal System01:21

Hepatic Portal System

The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...

Nursing Interventions I: Taxonomy of Nursing Interventions

Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...
