Partial splenic artery embolization in portal hypertension patients with hypersplenism: Two interval-spaced sessions’ technique
AbstractPurposeTo evaluate the ability of interval spaced sessions of transcatheter partial splenic artery embolization (PSE) to avoid the potential post procedure major complications, in portal hypertension patients with hypersplenism.Material and methodsThe study included 50 patients (39 male and 11 females). All patients had liver cirrhosis and portal hypertension with hypersplenism and hyperactive bone marrow. All patients underwent PSE in two sessions separated at least by 1month interval. Immediate, short and intermediate term follow-up for 1year were done.ResultsWe had no post procedure mortality. None of the patients developed septic shock, splenic abscess or needed emergency surgery. Ten of our patients developed subcapsular collections which were treated conservatively. All of our patients showed significant increase in the thrombocyte count after the first session which becomes remarkable after the second session and remained at appropriate levels during the follow up period.ConclusionPSE using two (interval-spaced) sessions with careful pre- and post procedure medications and care; is really effective non surgical minimally invasive procedure in avoiding the potential post procedure complications while achieving remarkable hematologic response on controlling hypersplenism in cirrhotic patients with portal hypertension
Solitary Wave Solution for Fractional-Order General Equal-Width Equation via Semi Analytical Technique
This paper presents an innovative approach to solve equal-width time-fractional-order equations that describe the behavior of waves in a certain physical system, using the Caputo operator to express the fractional derivative by improving the Taylor series expansion.Its convergence theorem is proven, and the error between the exact and approximate solutions is estimated; the resulting solutions are illustrated using graphs for different values of the fractional derivative order and time.The primary objective of this study is to demonstrate the effectiveness of the method in reducing computational effort for solving nonlinear fractional partial differential equations (NFPDEs)
Solving Nonlinear Fractional PDEs with Applications to Physics and Engineering Using the Laplace Residual Power Series Method
The Laplace residual power series (LRPS) method uses the Caputo fractional derivative definition to solve nonlinear fractional partial differential equations. This technique has been applied successfully to solve equations such as the fractional Kuramoto–Sivashinsky equation (FKSE) and the fractional generalized regularized long wave equation (GRLWE). By transforming the equation into the Laplace domain and replacing fractional derivatives with integer derivatives, the LRPS method can solve the resulting equation using a power series expansion. The resulting solution is accurate and convergent, as demonstrated in this paper by comparing it with other analytical methods. The LRPS approach offers both computational efficiency and solution accuracy, making it an effective technique for solving nonlinear fractional partial differential equations (NFPDEs). The results are presented in the form of graphs for various values of the order of the fractional derivative and time, and the essential objective is to reduce computation effort
