In this study, the authors reported a nursing case where a peripheral pseudoaneurysm with associated thrombosis that developed following an accidental arterial puncture were successfully cured after effective nursing procedures.  \nCase Presentation: A 55-year-old female patient arrived at the dialysis center for plasma exchange therapy due to antineutrophil cytoplasmic antibodies-related vasculitis. A 17 G puncture needle was used for cannulation of the left median cubital vein to establish the venous access, while the needle penetrated into the adjacent artery by mistake and resulting in a pseudoaneurysm. The needle was promptly withdrawn, followed by immediate pressure bandaging, ice application, and magnesium sulfate wet compresses. After adequate evaluation, percutaneous intra-arterial balloon dilatation and left brachial artery repair were performed, and the patient achieved near-complete resolution without any complications. Management and Outcome: Immediate hemostasis should be achieved by simultaneously withdrawing the needle and applying an elastic tourniquet. The prompt application of an ice compress is recommended to induce vasoconstriction, thereby reducing local hemorrhage and edema. Furthermore, magnesium sulfate wet compress was believed to facilitate the absorption of interstitial fluid and reduce capillary pressure. These combined measures are considered effective in preventing the formation and progression to a puncture-related pseudoaneurysm. Meticulous nursing care throughout is paramount to minimizing the risk of this complication and promoting patient recovery.  \nDiscussion: Enhancing nurses’ puncture proficiency is the cornerstone of preventing iatrogenic pseudoaneurysms and the pseudoaneurysms can be cured by efficient nursing that should include elastic tourniquet compression, ice compression, magnesium sulfate wet compression. Although a rare event, pseudoaneurysm can result from a commonly performed procedure such as vascular puncture. Therefore, it is imperative for nursing staff to be proficient in its early recognition and initial management.  \nKeywords  \npseudoaneurysm, nursing care, elastic tourniquet compression, ice compression, magnesium sulfate wet compression  \nReceived: July 21, 2024; revised: October 29, 2025; accepted: December 2, 2025  \nIntroduction  \nPlasma exchange therapy (PET) is recommended as a firstline or initial treatment for various hematologic, neurologic, and oncologic conditions. Procedurally, plasma is first separated from the blood using a plasma separator made of a fibrous membrane molecular sieve and adsorbent materials in the extracorporeal circulation (Gao et al., 2018) . The separated plasma is then discarded and replaced with an equivalent volume of substitution fluid before the blood is reinfused into the patient (Derebail & Falk, 2020) . A new peripheral venous access for the fluid infusion should be established when there  \nis not enough access to a dialysis machine. However, most patients undergoing PET have underlying conditions such  \n1 Department of Nephrology, Southwest Hospital, Army Medical University, Chongqing, China  \n*These authors contributed equally.  \nCorresponding Author:  \nGe Cao, Department of Nephrology, Southwest Hospital, Army Medical University, Chongqing 400038, China.  \nEmail: [caoge@tmmu.edu.cn](caoge@tmmu.edu.","cbCaiaNeYLlXeyKj","https://ap.wps.com/l/cbCaiaNeYLlXeyKj","pdf",777673,"English","# Abstract\n# Introduction\n# Case Presentation, Management, and Outcomes\n# Discussion\n# Keywords\n# Received, Revised, Accepted","[{\"question\":\"What caused the pseudoaneurysm in this case report?\",\"answer\":\"The pseudoaneurysm developed after an accidental arterial puncture during peripheral venous cannulation for plasma exchange therapy.\"},{\"question\":\"Which initial nursing measures were used after the mistaken puncture?\",\"answer\":\"The needle was promptly withdrawn with immediate pressure bandaging and ice application, followed by magnesium sulfate wet compresses after evaluation.\"},{\"question\":\"How was the patient ultimately treated and what was the outcome?\",\"answer\":\"After adequate evaluation, percutaneous intra-arterial balloon dilatation and left brachial artery repair were performed, leading to near-complete resolution without complications.\"}]","Management and Nursing Care of a Pseudoaneurysm Caused by Inadvertent Arterial Puncture - A Case Report | PDF",1790718970]
