Background. This paper aimed to prospectively evaluate the safety of embolization therapy of pulmonary arteriovenous malformations (PAVMs) for the detection of cerebral infarctions by pre- and post-interventional MRI. Method One hundred and five patients (male/female = 44/61; mean age 48.6+/−15.8; range 5–86) with pre-diagnosed PAVMs on contrast-enhanced MRA underwent embolization therapy. The number of PAVMs treated in each patient ranged from 1–8 PAVMs. Depending on the size and localization of the feeding arteries, either Nester-Coils or Amplatzer vascular plugs were used for embolization therapy. cMRI was performed immediately before, and at the 4 h and 3-month post-embolization therapy. Detection of peri-interventional cerebral emboli was performed via T2w and DWI sequences using three different b-values, with calculation of ADC maps. Results Embolization did not show any post-/peri-interventional, newly developed ischemic lesions in the brain. Only one patient who underwent re-embolization and was previously treated with tungsten coils that corroded over time showed newly developed, small, diffuse emboli in the post-interventional DWI sequence. This patient already had several episodes of brain emboli before re-treatment due to the corroded coils, and during treatment, when passing the corroded coils, experienced additional small, clinically inconspicuous brain emboli. However, this complication was anticipated but accepted, since the vessel had to be occluded distally. Conclusion Catheter-based embolization of PAVMs is a safe method for treatment and does not result in clinically inconspicuous cerebral ischemia, which was not demonstrated previously.

Treatment Principles

The era where surgical excision alone was the sole treatment of venous malformation (VM) is now over. A multidisciplinary approach that utilizes both traditional surgical therapy and endovascular therapy is now the standard of care. Endovascular therapy utilizing primarily both embolization therapy and sclerotherapy is the treatment of choice for surgically ‘inaccessible' VM lesions. Surgical therapy of VM lesions has been shown to be more effective when combined with supplemental endovascular therapy.

Abstract Background: Adrenocortical carcinoma(ACC) is a rare and highly invasive endocrine malignant tumor with poor prognosis and insensitivity tochemotherapy, which don't have effective treatment. Although Surgical resection is considered to be the main treatment for ACC, postoperative recurrence and metastasis have become the most important factors of death. Therefore, local treatments such as trans-catheter arterial chemo-embolization, radiofrequency ablation become be new treatment for ACC. Trans-catheter arterial chemo-embolization therapy for ACC patients with liver metastasis has good efficacy and can effectively reduce the tumor burden of patients, which is considered to be safe and easy for patients. Case presentation: We report a 47-year-old female patient diagnosed with stage Ⅳ ACC with liver metastases, who developed symptoms of acute adrenocortical dysfunctions after hepatic arterial catheter chemo-embolization.Conclusion: Trans-catheter arterial chemo-embolization therapy for ACC patients with liver metastasis is not completely safe, and there is a certain probability that it will lead to secondary adrenal dysfunction. Hydrocortisone supplementation can effectively alleviate the symptoms.
