Hepatic infarction occurred after 125I particle stent treatment for hepatocellular carcinoma with portal vein tumor thrombus: A case report.

BACKGROUND: Hepatic infarction is a rare liver condition. The purpose of this study is to report a case of hepatic infarction caused by thrombus formation following portal vein stent implantation in a patient with hepatocellular carcinoma and portal vein tumor thrombus, and to explore the underlying causes. CASE REPORT: The patient in this study was a 52-year-old male admitted with diffuse hepatocellular carcinoma involving the right lobe and portal vein tumor thrombus. After undergoing portal vein stent implantation and 125I particle strand implantation treatment, the portal vein was patent, and the pressure decreased. However, multiple instances of hepatic artery chemoembolization combined with targeted immunotherapy resulted in gradual reduction in the diameter of the hepatic artery and affecting hepatic arterial blood flow. Two months post-stent implantation, thrombus formation within the stent was noted, and the patient's condition did not improve with anticoagulant therapy, as evidenced by follow-up CT scans showing an increase in thrombi. Six months later, the patient suffered from gastrointestinal bleeding and, despite emergency esophagogastric variceal ligation and hemostatic treatment, developed hepatic parenchymal infarction and liver function failure. CONCLUSIONS: We reveal the underlying cause is that (1) thrombus formation within the portal vein stent, leading to portal vein embolism and obstructed blood flow due to exacerbate portal hypertension after various treatments; and (2) the effect of hepatic artery chemoembolization, immunotherapy, and targeted therapy on tumor angiogenesis, causing reduced hepatic artery diameter and impaired arterial blood flow. These factors disrupt the liver's dual blood supply system, ultimately contributing to hepatic infarction. To our knowledge, this is the first report of hepatic infarction as a complication following portal vein stent implantation for hepatocellular carcinoma with portal vein tumor thrombus, and it holds significant reference value for guiding the treatment of hepatocellular carcinoma with concurrent portal vein tumor thrombus in a clinical setting.

The effectiveness of the Escape Room as an educational methodology in the Infarction Code.

OBJECTIVE: To evaluate the efficacy of an educational intervention (escape room) in the acquisition and retention of knowledge in relation to the Infarction Code, and to compare the knowledge of other teaching methodologies related to the Infarction Code. METHODS: A pre-post study was designed without a control group. After one month of the master class on the Infarction Code given to master's degree (doctors and nurses), an educational intervention was carried out consisting of an Escape Room on the same content, with a questionnaire that collected various sociodemographic data, and a knowledge test on the Infarction Code, which was repeated immediately after the activity and at the end of 2 months after the activity, and a test of knowledge on the Infarction Code. immediately after the activity and 2 months after the master class. Likewise, after the activity, a gamified experience evaluation questionnaire (GAMEX) was completed. RESULTS: Thirty-two students received the educational intervention (12 physicians and 20 nurses), and differences were observed between medical and nursing professionals in terms of initial knowledge of simulation and gamification. After the activity, and based on the initial knowledge test, the score increased by 3.49 points, an increase that was also reflected in the test taken two months after the master class, where an increase of 2.08 points was maintained. The participants rated the experience positively, with no significant overall differences between the two professional groups. CONCLUSIONS: The nurses had greater knowledge and contact with clinical simulation, virtual reality and gamification. The escape room showed to be a valid method for the assimilation and retention of knowledge in master's degree students. Medical professionals experienced a greater degree of immersion in the activity.

A woman in her thirties with dyspnoea two weeks after abdominoplasty. / En kvinne i 30-årene med dyspné to uker etter bukplastikkoperasjon.

Background: While most cases of venous thromboembolism follow a benign course, occasionally the condition may manifest a complex clinical presentation and need a comprehensive diagnostic workup to identify the underlying cause and provide the patient with appropriate treatment. Case presentation: A woman in her late thirties presented to the emergency department with a five-day history of dyspnoea. She had recently undergone liposuction surgery after pregnancy. Upon admission, initial investigations revealed a pulmonary embolism with right heart strain, and she was treated with anticoagulants. The following day, she complained of acute-onset right flank pain without fever or other accompanying symptoms. A CT scan of the abdomen confirmed a right-side renal infarction. Further investigations revealed patent foramen ovale between the right and left atria of the heart, believed to be the source of a right-to-left shunt of arterial emboli. Although the patient had not suffered a clinical stroke, it was decided to close this defect using percutaneous technique. Interpretation: Patent foramen ovale is a common condition in adults, but in most cases it remains asymptomatic. However, patients with patent foramen ovale have an elevated risk of arterial emboli affecting multiple organs. The diagnosis depends on thorough assessment to prevent potentially fatal outcomes.

Sildenafil-induced spinal cord infarction: a case report.

Spinal cord infarction is a rare condition, accounting for only a small percentage of strokes. It can be classified into cervical and thoracolumbar infarctions, with various factors contributing to its occurrence. Sildenafil, a phosphodiesterase type 5 inhibitor commonly used for erectile dysfunction, has been associated with cardiovascular side effects, including transient hypotension. In this case report, we present the unusual occurrence of spinal cord infarction in a 65-year-old man who had self-administered high doses of sildenafil without a doctor's prescription. The patient experienced severe radicular pain in the lumbar region and subsequent weakness in the lower limbs. Evaluation revealed an anterior spinal cord infarction in the thoracic region, confirmed by MRI imaging. After excluding other potential causes, it was concluded that the intake of sildenafil likely led to systemic hypotension, resulting in spinal cord infarction. This case highlights the importance of considering sildenafil as a possible contributor to spinal cord infarction, particularly when used at high doses. Further studies are needed to better understand the relationship between sildenafil and vascular complications, including spinal cord infarction.

Multimodal ultrasound diagnosis of epididymo-orchitis with secondary testicular infarction: A case report.

We report a case of a 48-year-old man with testicular infarction caused by epididymo-orchitis (EO). Multimodal ultrasound showed extensive necrosis of the testis, and the patient underwent right orchiectomy. Postoperative pathology confirmed extensive necrosis of the testis. After 3 months of follow-up, the examination of scrotal ultrasound showed that the left testis and epididymis had no obvious abnormality.

Transverse spinal cord infarction following immunoglobulin treatment in a patient with exfoliative dermatitis: A case report.

RATIONALE: Transverse spinal cord infarction (SCI) is rare but highly disabling. Aortic thrombosis was described as one of the most common etiologies. Thromboembolic complications associated with intravenous immunoglobulin (IVIG) have been reported. PATIENT CONCERNS: A previously well, 64-year-old man who was given the treatment of IVIG (0.4 g/kg/d for 5 days) for exfoliative dermatitis 2 weeks before, progressively developed flaccid paraplegia of lower extremities, loss of all sensations below T3 level and urinary incontinence within 50 minutes. DIAGNOSES: A diagnosis of SCI and pulmonary embolism was made. IVIG was considered the possible cause. INTERVENTIONS: Anticoagulation treatment and continuous rehabilitation were administered. OUTCOMES: The neurologic deficiency of the patient was partially improved at the 3-year follow-up. LESSONS: The rapid development of severe deficits within 4 hours mostly contributes to the diagnosis of SCI. Heightened awareness of possible thrombotic events is encouraged for a month-long period following IVIG therapy.

Hepatic infarction in pregnancy: a systematic review.

OBJECTIVE: Hepatic infarction is a rare complication of pregnancy most often associated with hemolysis, elevated liver enzymes, and low platelets syndrome. The objective of this review is to identify risk factors, present signs and symptoms, identify methods of diagnosis, and identify best management practices on the basis of published case reviews. DATA SOURCES: PubMed and MEDLINE (Ovid) databases were searched for citations regarding hepatic infarction in pregnancy or the postpartum period from database inception until the study date of December 18, 2023. Key words included "liver infarction" or "hepatic infarction" and "pregnancy" or "obstetrics." STUDY ELIGIBILITY CRITERIA: Case reviews or case series published in the English language were included. Our study was registered with the Prospective Register of Systematic Reviews (registration number CRD42023488176) and was conducted in accordance with the published Prospective Register of Systematic Reviews and Meta-analyses Of Observational Studies in Epidemiology guidelines. METHODS: Included papers were evaluated for bias using a previously published tool. RESULTS: A total of 38 citations documenting 50 pregnancies published between 1979 and 2023 were included. Of these, 34% had a history of hypertensive disease, 26% had antiphospholipid syndrome, and 22% had a history of thrombus. Of those without a preexisting diagnosis of antiphospholipid syndrome, 24% tested positive during hospitalization. Most patients presented with epigastric or right upper quadrant pain (78%), and 32% and 16% had severe blood pressure or mild blood pressure, respectively. Sixty-four percent of patients presented with transaminitis. Forty-six percent of patients delivered preterm, and 32% of pregnancies ended in intrauterine fetal demise, abortion, or early termination of pregnancy for maternal benefit. Computed tomography scans were used to confirm diagnosis of hepatic infarction in 58% of cases, magnetic resonance imaging in 14%, and ultrasound in 6%. In cases that described management, treatment was always multimodal, including antihypertensives (18%), therapeutic anticoagulation (45%), blood product transfusion (36%), plasma exchange or intravenous immunoglobulin (20%), and steroids (39%). Transfer to the intensive care unit was required in 20% of cases. CONCLUSION: Hepatic infarction should be considered in all cases of hemolysis, elevated liver enzymes, and low platelets syndrome, but specifically in patients with a history of antiphospholipid syndrome who present with epigastric or right upper quadrant pain. The diagnosis can usually be confirmed with a computed tomography scan alone, and management should be prompt with supportive care, therapeutic anticoagulation, and steroids.

Neurophysiological findings in conus medullaris infarction-a case report and systematic review of the literature.

INTRODUCTION: Conus medullaris infarction (CMI) is a rare vascular phenomenon that has been scarcely reported in the literature. While previous studies have described the clinical and radiological features of CMI, little attention has been paid to its associated neurophysiological findings. METHODS: We present a case of idiopathic CMI and its neurophysiological findings, then present our findings from a systematic review of other reports of CMI with neurophysiological features found via PubMed search. RESULTS: Nine articles describing ten cases of CMI with associated neurophysiological data were found, in addition to our case. Out of all 11 cases, 7 cases (64%) had absent F-waves on the first nerve conduction study (NCS) performed as early as 4 h after onset, 5 of whom demonstrated reappearance of F-waves on subsequent follow-up NCS. Seven patients (64%) had diminished compound muscle action potentials (CMAPs), which was usually detectable on NCS performed between day 8 and day 18 of onset. None of them showed recovery of CMAPs in follow-up studies. Four patients (36%) had absent H-reflexes and two patients (18%) had sensory abnormalities. Electromyography (EMG) was reported in seven patients (64%), showing reduced recruitment as early as day 1 of onset, and denervation potentials as early as 4 weeks after onset. CONCLUSION: Absent F-waves and diminished CMAPs are the most common NCS abnormalities in CMI. Absent F-waves are detectable very early but tend to recover on subsequent NCS, while diminished CMAPs are detectable later but do not seem to resolve. Further research to determine the utility of neurophysiological studies in CMI diagnosis and prognostication is needed.

Multiscale X-ray phase-contrast CT unveils the evolution of bile infarct in obstructive biliary disease.

Bile infarct is a pivotal characteristic of obstructive biliary disease, but its evolution during the disease progression remains unclear. Our objective, therefore, is to explore morphological alterations of the bile infarct in the disease course by means of multiscale X-ray phase-contrast CT. Bile duct ligation is performed in mice to mimic the obstructive biliary disease. Intact liver lobes of the mice are scanned by phase-contrast CT at various resolution scales. Phase-contrast CT clearly presents three-dimensional (3D) images of the bile infarcts down to the submicron level with good correlation with histological images. The CT data illustrates that the infarct first appears on day 1 post-BDL, while a microchannel between the infarct and hepatic sinusoids is identified, the number of which increases with the disease progression. A 3D model of hepatic acinus is proposed, in which the infarct starts around the portal veins (zone I) and gradually progresses towards the central veins (zone III) during the disease process. Multiscale phase-contrast CT offers the comprehensive analysis of the evolutionary features of the bile infarct in obstructive biliary disease. During the course of the disease, the bile infarcts develop infarct-sinusoidal microchannels and gradually occupy the whole liver, promoting the disease progression.

Glycated serum protein is independently associated with progressive infarction in patients with acute ischemic stroke.

OBJECTIVE: This study investigated the relationship between glycated serum protein (GSP) and progressive infarction (PI). METHODS: From April 2017 to December 2020, we recruited 477 patients within 48 hours after the onset of acute ischemic stroke into this case-control study. Demographic characteristics, clinical information, and laboratory and neuroimaging data were recorded after admission. RESULTS: PI occurred in 144 (30.8%) patients. Patients with PI had higher initial National Institute of Health Stroke Scale (NIHSS) scores, higher discharge NIHSS scores, higher modified Rankin scale scores at 3 months after onset, higher GSP levels, lower prothrombin times, and lower creatinine levels than patients without PI. The likelihood of PI increased with increases in the GSP quartile. Multiple regression analysis revealed that high GSP levels (>2.14 mmol/L) were independently associated with PI. Subgroup analyses identified high GSP levels as an independent predictor of PI in patients with large artery atherosclerosis (third quartile: odds ratio [OR] = 3.793; 95% confidence interval [CI] = 1.555-9.250; fourth quartile: OR = 2.675; 95% CI = 1.056-6.776) and anterior circulation small vessel occlusion (fourth quartile: OR = 13.859; 95% CI = 2.024-94.885). CONCLUSIONS: GSP might be an independent predictor for PI in certain patients with acute ischemic stroke.

Shen Shuai II recipe improves renal hypoxia to attenuate renal injury in 5/6 renal ablation/infarction rats and effect evaluation using blood oxygenation level-dependent functional magnetic resonance imaging.

Background: Renal hypoxia plays a key role in the progression of chronic kidney disease (CKD). Shen Shuai II Recipe (SSR) has shown good results in the treatment of CKD as a common herbal formula. This study aimed to explore the effect of SSR on renal hypoxia and injury in CKD rats. Methods: Twenty-five Wistar rats underwent 5/6 renal ablation/infarction (A/I) surgery were randomly divided into three groups: 5/6 (A/I), 5/6 (A/I) + losartan (LOS), and 5/6 (A/I) + SSR groups. Another eight normal rats were used as the Sham group. After 8-week corresponding interventions, blood oxygenation level-dependent functional magnetic resonance imaging (BOLD-fMRI) was performed to evaluate renal oxygenation in all rats, and biochemical indicators were used to measure kidney and liver function, hemoglobin, and proteinuria. The expression of fibrosis and hypoxia-related proteins was analyzed using immunoblotting examination. Results: Renal oxygenation, evaluated by BOLD-fMRI as cortical and medullary T2* values (COT2* and MET2*), was decreased in 5/6 (A/I) rats, but increased after SSR treatment. SSR also downregulated the expression of hypoxia-inducible factor-1α (HIF-1α) in 5/6 (A/I) kidneys. With the improvement of renal hypoxia, renal function and fibrosis were improved in 5/6 (A/I) rats, accompanied by reduced proteinuria. Furthermore, the COT2* and MET2* were significantly positively correlated with the levels of creatinine clearance rate (Ccr) and hemoglobin, but negatively associated with the levels of serum creatinine (SCr), blood urea nitrogen (BUN), serum cystatin C (CysC), serum uric acid (UA), 24-h urinary protein (24-h Upr), and urinary albumin:creatinine ratio (UACR). Conclusion: The degree of renal oxygenation reduction is correlated with the severity of renal injury in CKD. SSR can improve renal hypoxia to attenuate renal injury in 5/6 (A/I) rats of CKD.

Clinical study of tirofiban compared to low molecular weight heparin in the antithrombotic treatment of progressive pontine infarction.

OBJECTIVE: To investigate the efficacy and safety of tirofiban and low molecular weight heparin (LMWH) in the treatment of patients undergoing acute progressive pontine infarction. PATIENTS AND METHODS: Patients with acute progressive pontine infarction who were hospitalized in the Neurology Department from June 2021 to June 2023 were included in the study and randomly divided into two groups, namely the experimental group (tirofiban group) and the control group (LMWH group). All patients in both groups were required to receive conventional comprehensive treatment and dual antiplatelet therapy with aspirin + clopidogrel at the beginning of admission. The National Institutes of Health Stroke Scale (NIHSS) score and Barthel Index (BI) were used to evaluate the neurological deficits on the first day of admission, the next day with stroke progression, and at discharge after treatment with tirofiban and LMWH, respectively in the two groups. The modified Rankin Scale was employed to assess prognosis on the 90th day after treatment. Clinical adverse events were followed up for 90 days, comparing the clinical efficacy and safety of the two treatment methods. RESULTS: There was no statistical significance in NIHSS score and Barthel Index between the tirofiban group and the LMWH group on the first day of admission and the next day with stroke progression (p > 0.05). After stroke progression, tirofiban and LMWH were separately used for treatment in the two groups. We found that the NIHSS score of the tirofiban group was lower than that of the LMWH group, and the Barthel Index score was higher than that of the LMWH group at discharge (p < 0.05). After three months of follow-up, the mRS score of the tirofiban group was dramatically higher than that of the LMWH group (p < 0.05). No significant harmful or adverse reactions, such as bleeding events, were found in the two groups (p > 0.05). CONCLUSIONS: Tirofiban may be more effective and safer than LMWH in controlling the progression of acute pontine infarction, but further and large-sample studies are still needed to confirm this finding.

Incidence of atrial fibrillation in patients with renal infarction: A retrospective cohort analysis of the Korean national health insurance registry.

BACKGROUND: Regarding the pathophysiology of renal infarction (RI), cardioembolic causes could have large proportion. However, there are notable variations in prevalence of atrial fibrillation (AF) among patients with RI across different studies, ranging from 17 to 65%. The primary objective of this study is to analyze the incidence of AF in patients with RI. METHODS: This nationwide retrospective cohort study enrolled 5200 patients with RI from the Korean National Institute of Health Services database spanning the years 2013 to 2019. The study accessed the AF incidence rate within 12 months in patients without a prior history of AF. Events occurring within 3 months of RI diagnosis were excluded to mitigate cases diagnosed during the initial screening or those with AF diagnoses that were potentially overlooked in the past. RESULTS: AF occurred in 19.1% of patients with RI over the entire period (median: 2.5 years, interquartile range 1.04-4.25 years). The majority of AF cases (16.1%) occured within the first year, resulting in an overall incidence rate of 7.0 per 100 person-years. Patients with newly developed AF were, on average, older than those who did not develop AF (64.1 vs. 57.3 years, P < 0.001). The independent predictors of AF were identified as age, male sex, higher body mass index, current smoking, ischemic heart disease, and heart failure. CONCLUSIONS: Physicians should consider the implementation of active rhythm monitoring for patients with RI to identify potential occurrence of subclinical AF, even if not initially diagnosed during the initial screening after RI diagnosis.

[A case of high cervical cord infarction presenting with cardiopulmonary arrest due to respiratory dysfunction].

A 46-year-old man with neck pain and impaired physical mobility called for emergency medical services. The patient was able to communicate with the emergency medical team upon their arrival. However, he went into cardiopulmonary arrest 5 minutes later. Cardiopulmonary resuscitation was immediately performed, and the patient was admitted to our hospital with a Glasgow Coma Scale score of E1V1M1. His respiratory rate was 5 breaths/minute and his partial pressure of carbon dioxide in arterial blood (PaCO2) was 127 |mmHg, necessitating intubation and ventilation. His consciousness improved as the PaCO2 level decreased. However, he was unable to be weaned off the ventilator and breathe independently. Neurological examination revealed flaccid quadriplegia, pain sensation up to the C5 level, absence of deep tendon reflexes, indifferent plantar responses, and absence of the rectoanal inhibitory reflex. Magnetic resonance imaging showed a hyperintense lesion with slight enlargement of the anterior two-thirds of the spinal cord at the C2-C4 level on both T2-weighted and diffusion-weighted images, consistent with a diagnosis of spinal cord infarction. Although the quadriplegia and sensory loss partially improved, the patient was unable to be weaned from the ventilator. Cervical cord infarction of the anterior spinal artery can cause rapid respiratory failure leading to cardiopulmonary arrest. Therefore, cervical cord infarction should be included as a differential diagnosis when examining patients after cardiopulmonary resuscitation.

Estimation of prognosis in patients after decompressive craniectomy after malignant hemispheric infarction: multifactorial scoring scale.

BACKGROUND: Patient's age is considered to be one of the most relevant factors in selecting surgical candidates for decompressive hemicraniectomy after malignant hemispheric infarction. However, questions about surgical indication in older patients, patients with consciousness disorder or patients with large infarctions remain unanswered. OBJECTIVE: Our aim was to design a multifactorial scoring scale based on a combination of patient-specific factors in order to optimize the assessment of prognosis in patients after hemicraniectomy malignant strokes. METHODS: In this prospective observational study with a one-year follow-up, we assessed clinical and imaging data of patients who underwent decompressive hemicraniectomy due to malignant brain infarction. Barthel index was used as a single outcome measure to distinguish favorable vs. unfavorable outcomes. Associations between multiple variables and clinical outcome were assessed. Subsequently, a design of a predictive scoring system was proposed. RESULTS: Age of the patient, preoperative level of consciousness, midline shift, and volume of infarction showed a significant association with postoperative Barthel index. According to the identified factors, a multifactorial prognostic scoring system was introduced, aimed to distinguish between favorable and unfavorable outcomes. Using ROC analysis, it has achieved an AUC of 0.74 (95%CI 0.58‒0.89, p=0.01)CONCLUSIONS: Prediction of postoperative outcome should be based on multiple variables. Our scale, based on the clinical and imaging data, can be used during decision-making to estimate potential benefit of decompressive craniectomy in patients after malignant brain infarction (Tab. 5, Fig. 1, Ref. 32).

A 38-Year-Old Woman With REM Predominant Central Sleep Apnea After Bulbar Infarction.

CASE PRESENTATION: A 38-year-old previously healthy woman was referred to our sleep center for recurrent witnessed breathing arrest during sleep. She had been brought to the ED 3 months earlier because of sudden onset of dizziness with nausea and vomiting, numbness and weakness of the left limb, less clear speech, double vision, dysphagia, and choking cough while drinking water. Brain MRI showed an acute cerebral infarction in the left medulla oblongata (Fig 1). High-resolution MRI showed vertebral artery dissection (Fig 2). Antiplatelet aggregation, lipid reduction, plaque stabilization, and trophic nerve treatments were administered, and the left limb strength, speech, and swallowing function improved. She complained of poor sleep and difficulties with memory.
