INTRODUCTION

Uterine artery pseudoaneurysm (UAP) is a rare yet potentially life-threatening complication following hysteroscopic surgery. It generally results from iatrogenic trauma to the uterine artery during the procedure[1]. The case report by Kakinuma et al[1], published in the World Journal of Clinical Cases, detailed a notable instance of UAP that developed after hysteroscopy. This editorial explores the clinical implications of that case, emphasizing the diagnostic challenges, management strategies, and broader implications for patient management.

The diagnosis of UAP can be particularly challenging owing to its nonspecific presentation. UAP often mimics other postoperative complications[2]. Early detection is critical because UAP can progress to severe hemorrhage if left untreated[3]. Some cases of UAP can be managed conservatively, but other approaches including uterine artery embolization or surgical repair may be needed[2,4]. Clinicians performing gynecological surgeries must have a thorough understanding of the risks associated with UAP. Vigilant postoperative monitoring and prompt intervention are essential to prevent severe complications and to optimize patient outcomes[1,3].

CLINICAL PRESENTATION AND DIAGNOSIS

UAP following hysteroscopic surgery presents with a diverse range of clinical manifestations by Kakinuma et al[1]. The variable presentation necessitates a high index of suspicion among clinicians for a timely diagnosis, particularly for patients experiencing postoperative symptoms such as vaginal bleeding and abdominal pain or showing signs of hypovolemic shock[3]. Diagnostic imaging is pivotal in confirming UAP and guiding prompt intervention. Ultrasound is usually the initial diagnostic tool because of its availability and its ability to identify pulsatile hypoechoic masses indicative of pseudoaneurysms[5]. Doppler ultrasound further refines the assessment of blood flow patterns within pseudoaneurysms, and computed tomography angiography offers detailed anatomical localization and vascular mapping essential for surgical planning[2].

The published literature describes various clinical presentations and therapies of UAP. For example, Ota et al[3] reported successful management using temporary bilateral laparoscopic clamping of the uterine arteries followed by hysteroscopic surgery. Melcer et al[4] described a case of conservative management for UAP after cesarean delivery, highlighting the potential for nonsurgical interventions in selected scenarios. Takeda et al[6] reported the use of endovascular techniques to manage intractable delayed hemorrhage following laparoscopic-assisted vaginal hysterectomy, underscoring the utility of minimally invasive methods. Early recognition of UAP is crucial for preventing complications such as rupture or severe hemorrhage. Effective management of UAP and, where applicable, preservation of fertility often requires a multidisciplinary approach that combines laparoscopic and hysteroscopic techniques[7,8]. Integration of advanced imaging modalities with clinical expertise is instrumental in ensuring a timely diagnosis and successful management of UAP following hysteroscopic procedures.

MANAGEMENT STRATEGIES AND CHALLENGES

Effective management of UAP following hysteroscopic surgery requires a multidisciplinary approach that combines the expertise of gynecologists, interventional radiologists, and vascular surgeons[1]. Early recognition is crucial, allowing for application of a spectrum of therapeutic strategies ranging from conservative management with close monitoring to more invasive interventions such as embolization and surgical repair[3]. The optimal management strategy depends on various factors, including the clinical presentation, size, and location of the pseudoaneurysm, as well as patient preference[2]. Conservative management involves close observation with serial imaging to monitor pseudoaneurysm stability and regression over time[5]. This method is suitable for patients with minimal symptoms and hemodynamic stability.

The potential for recurrence necessitates individualized treatment plans tailored to each patient’s unique circumstances[9]. For cases requiring intervention, minimally invasive techniques such as temporary laparoscopic bilateral clamping of the uterine arteries followed by hysteroscopy have positive outcomes of fertility preservation and reduced surgical morbidity[7,8]. Embolization is an effective method, and is often preferred because it is minimally invasive and can successfully control bleeding and resolve pseudoaneurysms[6]. Published case reports have documented the successful application of these techniques. For example, Ota et al[3] described a case where temporary laparoscopic clamping of the uterine arteries followed by hysteroscopic surgery effectively treated UAP, highlighting the importance of preserving reproductive function. Similarly, Wang et al[7] reported the effectiveness of devices for manual removal of hysteroscopic tissue in patients with intrauterine pathologies, providing minimal surgical trauma and optimal reproductive outcomes. Although advances in imaging and therapeutic modalities have led to greatly improved outcomes, UAP management remains challenging owing to its variable clinical presentation and potential complications. An individualized, multidisciplinary approach ensures timely intervention and enhances patient safety and reproductive health outcomes. Tailored approaches address both the immediate risk posed by UAP and optimizes long-term reproductive outcomes for affected patients.

CLINICAL IMPLICATIONS AND FUTURE DIRECTIONS

UAP following hysteroscopic surgery presents a considerable challenge that influences both patient outcomes and the use of healthcare resources. Advances in surgical techniques and imaging protocols have reduced the risk of iatrogenic injury and help to prevent UAP[1]. Enhanced imaging modalities, such as Doppler ultrasound and magnetic resonance imaging, hold promise for improving diagnostic accuracy. That would facilitate early detection and timely intervention, which would improve patient outcomes[3]. Future studies should focus on refining the diagnostic criteria to optimize treatment algorithms and ultimately decrease the risk of UAP recurrence[2]. Prospective studies are needed to elucidate the natural history and long-term outcomes of UAP, particularly regarding reproductive health and fertility preservation[5]. Such investigations will contribute to the development of evidence-based guidelines, ultimately enhancing clinical decision-making in managing this complex condition. Ongoing advancements in diagnostic imaging and therapeutic strategies offer promise for reducing the incidence of UAP following hysteroscopy and improving its management. Collaborative efforts across disciplines are crucial for improving patient care and optimizing outcomes of individuals affected by this condition.

CONCLUSION

The case report by Kakinuma et al[1] underscores the importance of vigilance in recognizing and managing UAP, a rare but potentially life-threatening complication following hysteroscopic surgery. UAP has a broad spectrum of clinical presentations, which poses diagnostic challenges. This necessitates a high index of suspicion among clinicians, particularly for patients experiencing postoperative symptoms such as vaginal bleeding or abdominal pain. Management of UAP requires a multidisciplinary approach, including collaboration of gynecologists, interventional radiologists, and vascular surgeons to individualize treatment based on patient factors and clinical severity[3]. Stable patients may benefit from conservative management with close monitoring. However, cases with hemodynamic instability or persistent bleeding often require more aggressive interventions such as embolization and surgical repair[2]. Future research efforts should focus on refining diagnostic protocols to facilitate the early detection of UAP. In addition, optimizing treatment algorithms and conducting prospective studies are crucial for improving long-term patient outcomes and reducing UAP recurrence[5]. Moreover, exploring preventive strategies, including advancements in imaging techniques and procedural modifications, is important to minimize UAP incidence, to address the need for post-hysteroscopic surgery, and to improve patient safety. In conclusion, advancing our understanding of UAP and optimizing its management are crucial for ensuring timely and effective intervention in clinical practice, improving patient outcomes, and reducing the healthcare burden associated with this challenging complication.
