BACKGROUND Left cardiac myxoma(CM)is the most common benign tumor of primary cardiac tumors,but because of its special position caused by pathological physiology change,caused by the complications of the heavier,the surface is often accompanied by blood clots,once fall out,it causes peripheral vascular embolization,such as acute lower limb artery embo-lization,harmfulness is large,high morbidity,and easy to occur repeatedly.CASE SUMMARY A 67-year-old male patient suddenly appeared numbness and weakness of the left lower limb and could not walk without obvious incentive.The patient was finally diagnosed as left CM complicated with acute lower limb arterial embolism after completing cardiac ultrasound,computer tomography angiography,and histopathological analysis,such as hematoxylin-eosin stain staining,immunohistochemistry and special staining including alcian blue staining and periodic acid schiff staining.Arterial thrombosis was removed successfully by femoral artery thrombectomy,postoperative numbness and weakness of the patient’s left lower limb disappeared,skin temperature became warm,and dorsal foot artery pulsation was accessible.The patient was readmitted to the hospital 8 mo after discharge for left atrial mass resection,and was diagnosed as CM by postoperative histopathological examination.CONCLUSION Although CM is rare,it may be considered as the source of embolism in patients with acute limb ischemia.Repeated loss of thrombus on the tumor and its surface may lead to repeated embolism of peripheral vessels.Cardiac ultrasound is helpful for early diagnosis.Here,we use this case report to highlight left CM as an important cause of acute limb ischemia and to report our experience in the diagnosis and treatment of lower limb arterial embolism caused by CM detachment. 展开更多

BACKGROUND Hepatocellular carcinoma(HCC)is a prevalent malignancy,and transcatheter arterial embolization(TAE)has emerged as a pivotal therapeutic modality.How-ever,TAE may induce symptom distress and fatigue,adversely affecting the quality of life of patients.AIM To investigate symptom distress,fatigue,and associated factors in HCC patients undergoing TAE.METHODS We used a cross-sectional design and purposive sampling to enroll HCC patients who underwent TAE at our institution from January to December 2022.Question-naires were utilized to collect data on symptom distress and fatigue scores from the first to the third day after TAE.RESULTS Our study revealed a significant reduction in fatigue and symptom distress among patients after TAE.Pain,fatigue,insomnia,fever and abdominal dis-tension were the most common symptoms troubling patients during the first 3 d post-TAE.Marital status,presence of family support,physical functional status,age,and symptom distress were identified as predictors of fatigue in patients.CONCLUSION Healthcare professionals should educate HCC patients on symptom distress and INTRODUCTION Hepatocellular carcinoma(HCC)ranks as the fifth most prevalent cancer and the third leading cause of cancer-related mortality globally.Surgical intervention remains the cornerstone of HCC treatment;however,due to the challenges associated with early diagnosis and the lack of specific diagnostic markers,a considerable proportion of patients are diagnosed at advanced stages,rendering them ineligible for surgical interventions.Transcatheter arterial embolization(TAE)is an interventional therapeutic approach involving the insertion of a fine catheter via the femoral artery to reach the vasculature near the tumor site.TAE aims to obstruct the arterial supply to the tumor by deploying embolic agents,thereby inducing necrosis in cancer cells.This procedure is suitable for patients with good liver function and overall health,particularly those with large HCCs that have not invaded the portal vein[1,2].Nonetheless,following TAE,hepatocytes incur variable degrees of damage,leading to the development of a constel-lation of symptoms reminiscent of acute hepatitis.These symptoms include fatigue and systemic discomfort,such as nausea,vomiting,fever,abdominal pain,as well as transient elevations in aspartate aminotransferase(AST)and alanine aminotransferase(ALT),collectively referred to as postembolization syndrome[3,4].These symptoms may arise due to ischemia of the liver and gallbladder,temporary liver enlargement,and peritoneal irritation.While many studies have explored fatigue and symptom distress in cancer patients both nationally and internationally,with some focusing on symptom distress following transcatheter arterial chemoembolization,there has been limited in-depth investigation into the fatigue and symptom distress resulting from TAE treatment[5-8].Fatigue and pain are both subjective experiences,typically arising from the gradual depletion of energy reserves during the course of illness[9].Fatigue is particularly prevalent among cancer patients,with rates soaring as high as 90%.Despite extensive research exploring cancer-related fatigue and its influencing factors,a unanimous consensus remains elusive.Hence,the primary objective of this study was to investigate the symptom distress and fatigue experienced by liver cancer patients following TAE treatment and to analyze potential contributing factors. 展开更多

BACKGROUND Through significant advances in the treatment of peripheral arterial occlusive disease,acute ischemia of the lower extremity is still associated with significant morbidity,limb threat and mortality.The two main causes of acute ischemia in lower extremities are arterial embolism and atherosclerotic arteries.Timely recognition and treatment of acute limb ischemia in emergency situations is essential in order to minimize the duration of ischemia.AIM To investigate the application effect of angiojet thrombolysis in the treatment of acute lower extremity arterial embolization.METHODS Sixty-two patients with acute lower extremity arterial embolization admitted to our hospital from May 2018 to May 2020 were selected.Among them,the observation group(twenty-eight cases)had received angiojet thrombolysis,and the control group(thirty-four cases)had received femoral artery incision and thrombectomy.After thrombus clearance,significant residual stenosis of the lumen was combined with balloon dilation and/or stent implantation.When the thrombus removal was not satisfactory,catheter-directed thrombolysis was performed.The incidence of postoperative complications,recurrence rate and recovery of the two groups were compared.RESULTS There were no significant differences in postoperative recurrence(target vessel reconstruction rate),anklebrachial index and the incidence of postoperative complications between the two groups(P>0.05);there were statistically significant differences in postoperative pain score and postoperative rehabilitation between the two groups(P<0.05).CONCLUSION The application of angiojet in the treatment of acute lower limb artery thromboembolism disease is safe and effective,minimally invasive,quicker recovery after operation,less postoperative complications,which is more suitable for the treatment of femoral popliteal arterial thromboembolism lesions.If the thrombus removal is not satisfactory,the combination of coronary artery aspiration catheter and catheterized directed thrombolysis can be used.Balloon dilation and stent implantation can be considered for obvious lumen stenosis. 展开更多

BACKGROUND Klebsiella pneumoniae(K.pneumoniae)is a clinically common Gram-negative bacillus that can cause community-and hospital-acquired infections and lead to pneumonia,liver abscesses,bloodstream infections,and other infectious diseases;however,severe pneumonia caused by hypervirulent K.pneumoniae(hv Kp)complicated by acute intra-abdominal multiple arterial thrombosis and bacterial embolism is rarely seen in the clinical setting and has not been reported in the literature.CASE SUMMARY A 51-year-old man was hospitalized with fever and dyspnea.Persistent mild pain in the middle and upper abdomen began at dawn on the 3rd day following admission and developed into persistent severe pain in the left upper abdomen 8h later.Based on chest computed tomography(CT),bronchoscopy,bronchoalveolar lavage fluid metagenomic next-generation sequencing,abdominal aortic CT angiography(CTA),and culture of the superior mesenteric artery embolus,adult community-acquired severe hv Kp pneumonia complicated by acute intraabdominal multiple arterial thrombosis and bacterial embolism was diagnosed.Notably,he recovered and was discharged from the hospital after receiving effective meropenem anti-infection,endovascular contact thrombolytic,and systemic anticoagulant therapies and undergoing percutaneous thrombus aspiration.Ten days later,the patient returned to the hospital for abdominal CTA examination,which indicated blocked initial common pathway of the celiac trunk and superior mesenteric artery,and local stenosis.Therefore,celiac trunk artery stenting was performed in Chongqing Hospital,and postoperative recovery was good.CONCLUSION We report a case of hv Kp severe pneumonia complicated by acute intra-abdominal multiple arterial thrombosis and bacterial embolism and suggest that clinicians should consider the possibility of a Gram-negative bacillus infection and conduct effective pathogen detection in a timely fashion when managing patients with severe community-acquired pneumonia before obtaining bacteriologic and drug sensitivity results.At the same time,when patients have severe pulmonary infection complicated by severe abdominal pain,an acute mesenteric artery embolism should be considered to avoid delays in treatment. 展开更多

BACKGROUND Transcatheter arterial embolization(TAE)has been widely used as an effective and a safe treatment method and was often used as an alternative to the surgical management,but there are limited studies on the efficacy and the safety for patients undergoing their secondary postpartum hemorrhage(PPH).AIM To evaluate the usefulness of TAE for secondary PPH focusing on the angiographic findings.METHODS We conducted a research from January 2008 to July 2022 on all 83 patients(mean:32 years,range:24-43 years)presented with secondary PPH and they were treated with TAE in two university hospitals.The medical records and angiography were retrospective reviewed in order to evaluate the patients’characteristics,delivery details,clinical status and peri-embolization management,angiography and embolization details,technical/clinical success and complications.The group with active bleeding sign and the group without it were also compared and analyzed.RESULTS On angiography,46(55.4%)patients showed active bleeding signs such as contrast extravasation(n=37)or pseudoaneurysm(n=8)or both(n=1),and 37(44.6%)patients showed non-active bleeding signs such as only spastic uterine artery(n=2)or hyperemia(n=35).In the active bleeding sign group there were more multiparous patients,low platelet count,prothrombin time prolongation,and high transfusion requirements.The technical success rates were 97.8%(45/46)in active bleeding sign group and 91.9%(34/37)in non-active bleeding sign group,and the overall clinical success rates were 95.7%(44/46)and 97.3%(36/37).An uterine rupture with peritonitis and abscess formation occurred to one patient after the embolization,therefore hysterostomy and retained placenta removal were performed which was a major complication.CONCLUSION TAE is an effective and a safe treatment method for controlling secondary PPH regardless of angiographic findings. 展开更多

Rationale:Aortic dissection is a life-threatening medical emergency associated with high morbidity and mortality.Preoperative mesenteric malperfusion increases the surgical risk and mortality in patients with type B aortic dissection.For DeBakey type III B patients involving most of the thoracoabdominal aorta,endovascular treatment to improve true lumen perfusion may have limited benefits.Organ reperfusion on-time is crucial.Patient concerns:A 38-year-old man was admitted with sudden severe upper abdominal pain.Emergency CTA of the entire aorta revealed an aortic dissection with an entry tear in the descending aortic arch involving the celiac trunk,superior mesenteric artery,bilateral common iliac arteries and right external iliac artery,with thrombosis in the superior mesenteric artery.Diagnoses:The patient was diagnosed with DeBakey type III aortic dissection with mesenteric artery embolism.Enhanced chest CT showed the entry tear location and involvement of major arteries.Angiography confirmed partial blood flow in the superior mesenteric artery.Interventions:The patient underwent endovascular aortic stent-graft implantation through the left femoral artery,covering the descending aortic arch and sealing the entry tear.Postoperatively,the patient received intensive care,including ventilatory support,CRRT,anti-infection therapy,vasoactive drugs and lumbar cistern drainage.Outcomes:Two weeks postoperatively,the patient developed massive black stools,indicative of intestinal obstruction and necrosis.Exploratory laparotomy revealed ischemic necrosis and rupture of the stomach,small intestine,and colon.Despite surgical efforts,the patient’s condition deteriorated,leading to death from severe infection,acid-base imbalance and multiple organ failure. 展开更多

BACKGROUND We report a case of uterine artery pseudoaneurysm(UAP)occurrence during hysteroscopic endometrial polypectomy and its treatment via uterine artery embolization(UAE).CASE SUMMARY A 48-year-old primigravid,primiparous patient was incidentally found to have an endometrial polyp during a health checkup,and underwent a hysteroscopic polypectomy at another hospital.Her cervix was dilated with a Laminken-R®device.After the Laminken-R®was withdrawn,a large amount of genital bleeding was observed.This bleeding persisted after the hysteroscopic polypectomy,and,as hemostasis became impossible,the patient was transferred to our hospital by ambulance.On arrival,transvaginal ultrasonography revealed a 3-cm hypoechoic mass with a swirling internal pulse on the right side of the uterus,and color Doppler ultrasonography showed feeder vessels penetrating the mass.Pelvic contrast-enhanced computed tomography(CT)confirmed the presence of a mass at this site,and vascular proliferation was observed within the uterine cavity.Consequently,UAP was diagnosed,and UAE was performed.The patient’s postoperative course was uneventful,and 6 mo post-UAE,no recurrence of blood flow to the UAP was observed.CONCLUSION When abnormal genital bleeding occurs during hysteroscopic surgery,ultrasonography and contrast-enhanced CT can assist in the detection of early UAPs. 展开更多

BACKGROUND Hemorrhoidal artery embolization(Emborrhoid)is a novel method for the treatment of severe hemorrhoidal bleeding.Despite having a technical success rate of 93%-100%,the clinical success ranges between 63%and 94%,with a rebleeding rate of 13.6%.AIM To evaluate the effectiveness of this procedure in reducing hemorrhoidal flow and hemorrhoidal bleeding.METHODS This prospective observational pilot study was conducted at Division of General Surgery 1 and Tertiary Referral Pelvic Floor Center,Treviso Regional Hospital,Italy.In a 2 months period(February-March 2022),consecutive patients with hemorrhoidal bleeding scores(HBSs)≥4,Goligher scores of II or III,failure of non-operative management,and a candidate for Emborrhoid were included.Endoanal ultrasound with eco-Doppler was performed preoperatively and 1 month after the procedure.The primary endpoint was to quantify the changes in arterial hemorrhoidal flow after treatment.The secondary endpoint was to evaluate the correlation between the flow changes and the HBS.RESULTS Eleven patients underwent Emborrhoid.The overall pretreatment mean systolic peak(MSP)was 14.66 cm/s.The highest MSP values were found in the anterior left lateral(17.82 cm/s at 1 o’clock and 15.88 cm/s at 3 o’clock)and in the posterior right lateral(14.62 cm/s at 7 o’clock and 16.71 cm/s at 9 o’clock)quadrants of the anal canal.After treatment,the overall MSP values were significantly reduced(P=0.008)although the correlation between MSP and HBS changes was weak(P=0.570).A statistical difference was found between distal embolization compared with proximal embolization(P=0.047).However,the coil landing zone was not related to symptoms improvement(P=1.000).A significant difference in MSP changes was also reported between patients with type 1 and type 2 superior rectal artery(SRA)anatomy(P=0.040).No relationship between hemorrhoidal grades(P=1.000),SRA anatomy(P=1.000)and treatment outcomes was found.CONCLUSION The preliminary findings of this pilot study confirm that Emborrhoid was effective in reducing the arterial hemorrhoidal flow in hemorrhoidal disease.However,the correlation between the post-operative MSP and HBS changes was weak.Hemorrhoidal grade,SRA anatomy and type of embolization were not related to treatment outcomes. 展开更多

Uterine fibroids are benign tumors that originate from smooth muscle cells of the uterus.It is the most common gynecological disorder,affecting up to 80%of women of reproductive age.Uterine fibroids can cause various symptoms such as abnormal uterine bleeding,pelvic pain,infertility,and pregnancy complications.The treatment options for uterine fibroids include medical therapy,surgical intervention,and minimally invasive techniques.AIM To compare ovarian function of women with uterine fibroids who did or did not undergo uterine artery embolization(UAE).METHODS This prospective cohort study enrolled 87 women with symptomatic uterine fibroids who underwent UAE,and 87 women with the same symptoms who did not undergo UAE but received conservative management or other treatments.The two groups were matched for age,body mass index,parity,and baseline characteristics of uterine fibroids.The primary outcome was ovarian function that was evaluated by serum levels of follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2),and anti-Müllerian hormone(AMH),as well as ovarian reserve tests,such as antral follicle count(AFC)and ovarian volume(OV).The secondary outcome was fertility that was evaluated based on the menstrual cycle,ovulation,conception,pregnancy,and delivery.The participants were followed-up for 36 months and assessed at 1,3,6,12,24,and 36 months after treatment.RESULTS The study found that the most common minor complication of UAE was postembolization syndrome in 73.6% of women,resolving within a week.No significant differences were observed between the UAE group and the control group in serum levels of reproductive hormones(FSH,LH,E2,AMH)and ovarian reserve indicators(AFC,OV)at any point up to 36 months post-treatment.Additionally,there were no significant differences in conception,pregnancy,or delivery rates,with the average time to conception and gestational age at delivery being similar between the two groups.Birth weights were also comparable.Finally,there was no significant correlation between ovarian function,fertility indicators,and the type or amount of embolic agent used or the change in fibroids posttreatment.CONCLUSION UAE resulted in significantly positive pregnancy outcomes,no adverse events post-treatment,and is a safe and effective treatment for uterine fibroids that preserves ovarian function and fertility. 展开更多

This manuscript explores the case on the occurrence of uterine artery pseudoaneurysm(UAP)during hysteroscopy endometrial polypectomy and the subsequent successful treatment via uterine artery embolization(UAE).Moreover,we focus on the management and treatment options for UAP in patients of advanced maternal age.A pseudoaneurysm is an extraluminal blood collection with a disrupted flow that communicates with the parent vessel via a defect in the arterial wall.The reported case involved a 48-year-old primiparous woman who developed a UAP after uterine polyp removal.The study enhances the understanding of UAP,a rare but potentially life-threatening condition,by providing a detailed and well-documented account of the comprehensive case presentation,effective use of medical imaging techniques for diagnosis,successful postoperative patient management following UAE,and practical clinical recommendations for clinicians managing similar cases.Overall,this study highlights the importance of considering UAP as a differential diagnosis in patients with abnormal vaginal bleeding following hysteroscopic surgery.Additionally,this manuscript recommends that clinicians with a high index of suspicion for UAP promptly request ultrasonography and computed tomography to facilitate early diagnosis.UAE is suggested as a primary treatment due to its effectiveness and safety,particularly in facilities capable of avoiding hysterectomy. 展开更多

BACKGROUND Prostatic artery embolization(PAE)is a promising but also technically demanding interventional radiologic treatment for symptomatic benign prostatic hyperplasia.Many technical challenges in PAE are associated with the complex anatomy of prostatic arteries(PAs)and with the systematic attempts to catheterize the PAs of both pelvic sides.Long procedure times and high radiation doses are often the result of these attempts and are considered significant disadvantages of PAE.The authors hypothesized that,in selected patients,these disadvantages could be mitigated by intentionally embolizing PAs of only one pelvic side.AIM To describe the authors’approach for intentionally unilateral PAE(IU-PAE)and its potential benefits.METHODS This was a single-center retrospective study of patients treated with IU-PAE during a period of 2 years.IU-PAE was applied in patients with opacification of more than half of the contralateral prostatic lobe after angiography of the ipsilateral PA(subgroup A),or with markedly asymmetric prostatic enlargement,with the dominant prostatic lobe occupying at least two thirds of the entire gland(subgroup B).All patients treated with IU-PAE also fulfilled at least one of the following criteria:Severe tortuosity or severe atheromatosis of the pelvic arteries,non-visualization,or visualization of a tiny(<1 mm)contralateral PA on preprocedural computed tomographic angiography.Intraprocedural contrast-enhanced ultrasonography(iCEUS)was applied to monitor prostatic infarction.IU-PAE patients were compared to a control group treated with bilateral PAE.RESULTS IU-PAE was performed in a total 13 patients(subgroup A,n=7;subgroup B,n=6).Dose-area product,fluoroscopy time and operation time in the IU-PAE group(9767.8μGy∙m^(2),30.3 minutes,64.0 minutes,respectively)were significantly shorter(45.4%,35.9%,45.8%respectively,P<0.01)compared to the control group.Clinical and imaging outcomes did not differ significantly between the IU-PAE group and the control group.In the 2 clinical failures of IU-PAE(both in subgroup A),the extent of prostatic infarction(demonstrated by iCEUS)was significantly smaller compared to the rest of the IU-PAE group.CONCLUSION In selected patients,IU-PAE is associated with comparable outcomes,but with lower radiation exposure and a shorter procedure compared to bilateral PAE.iCEUS could facilitate patient selection for IU-PAE. 展开更多

BACKGROUND Gastrointestinal bleeding(GIB)is a severe and potentially life-threatening condition,especially in cases of delayed treatment.Computed tomography angiography(CTA)plays a pivotal role in the early identification of upper and lower GIB and in the prompt treatment of the haemorrhage.AIM To determine whether a volumetric estimation of the extravasated contrast at CTA in GIB may be a predictor of subsequent positive angiographic findings.METHODS In this retrospective single-centre study,35 patients(22 men;median age 69 years;range 16-92 years)admitted to our institution for active GIB detected at CTA and further submitted to catheter angiography between January 2018 and February 2022 were enrolled.Twenty-three(65.7%)patients underwent endoscopy before CTA.Bleeding volumetry was evaluated in both arterial and venous phases via a semi-automated dedicated software.Bleeding rate was obtained from volume change between the two phases and standardised for unit time.Patients were divided into two groups,according to the angiographic signs and their concordance with CTA.RESULTS Upper bleeding accounted for 42.9%and lower GIB for 57.1%.Mean haemoglobin value at the admission was 7.7 g/dL.A concordance between positive CTA and direct angiographic bleeding signs was found in 19(54.3%)cases.Despite no significant differences in terms of bleeding volume in the arterial phase(0.55 mL vs 0.33 mL,P=0.35),a statistically significant volume increase in the venous phase was identified in the group of patients with positive angiography(2.06 mL vs 0.9 mL,P=0.02).In the latter patient group,a significant increase in bleeding rate was also detected(2.18 mL/min vs 0.19 mL/min,P=0.02).CONCLUSION In GIB of any origin,extravasated contrast volumetric analysis at CTA could be a predictor of positive angiography and may help in avoiding further unnecessary procedures. 展开更多

BACKGROUND Acute mesenteric vein thrombosis(MVT)accounts for only 2%–10%of all cases of acute mesenteric ischaemia,with an incidence rate of~0.1%in Europe and the United States.It represents<10%of mesenteric infarction cases and is seen predominantly in older adults.In younger individuals,MVT is uncommon,with 36%of cases having unidentified mechanisms and causes.CASE SUMMARY A 27-year-old man presented to the emergency department on February 29,2024,with a chief complaint of intermittent abdominal pain for 3 day.He was previously in good health.As the abdominal pain was not alleviated by conventional treatment,an abdominal computed tomography(CT)scan was performed,which showed increased density in the portal and mesenteric veins.Further imaging,including portal vein ultrasound,mesenteric CT angiography,and enhanced abdominal CT,revealed widespread thrombosis of the portal vein system(including the main portal vein,left and right branches,proximal mesenteric vein,and splenic vein).After 10 day of thrombectomy and anticoagulation therapy,the patient’s abdominal pain had improved significantly.Follow-up assessments indicated that portal venous blood flow had largely returned to normal.He was discharged on March 9,2024.During a follow-up exam 2 months later,repeat abdominal enhanced CT showed that the previously detected thrombi were no longer visible.CONCLUSION Clinicians should remain vigilant for acute MVT in young patients presenting with abdominal pain,to prevent misdiagnosis of this fatal condition. 展开更多
