Transarterial Embolization in Neonatal Kasabach–Merritt Syndrome

Background: Kasabach–Merritt syndrome (KMS) is characterized by large hemangiomas and persistent thrombocytopenia, which may result in visceral hemorrhage and disseminated intravascular coagulation. This study aimed to evaluate the value of transarterial embolization (TAE) in neonatal KMS patients.Patients and Methods: The clinical course of 11 neonates with KMS who underwent TAE in the Department of Neonatology, Anhui Provincal Children's Hospital, Anhui Medical University, China, were reviewed retrospectively.Results: Eleven neonates with KMS (nine male and two female) were admitted to our hospital between the age of 1 h and 6 days. All were born with progressively enlarged hemangiomas and persistent thrombocytopenia. The largest lesion had its maximum size reached at 15 × 8 × 8 cm. Eight patients had cutaneous hemangiomas (1 right face, one oropharynx, one left upper arm, two back, one left lumbar, one right lower leg, and one right thigh), and three patients had liver hemangiomas. All 11 patients underwent TAE. Nine patients underwent two TAEs, and two patients underwent only one embolization procedure. They all obtained >80% devascularization of their lesions without a major complication. The platelet count increased at 2–5 days after treatment and reached normal count and coagulation profile at 18–28 days after the TAE.Conclusions: TAE is a safe and effective alternative therapy for neonatal KMS patients.

Embolization of Hemorrhoidal Arteries: A Novel Endovascular Therapy Option for the Treatment of Hemorrhoidal Disease

Background Hemorrhoids are a widespread disease. Treatment options range from dietary measures to open surgery. A novel treatment approach is the embolization of the hemorrhoidal arteries. Method A review was performed based on a selective literature search in PubMed representing the current state of research. The keywords “hemorrhoid” and “embolization” and “emborrhoid” were used. In addition, technical details of the hemorrhoidal embolization procedure are explained. Results and Conclusion Embolization of hemorrhoidal arteries is a safe treatment, which allows efficient symptom control even in patients with contraindications for open surgery.

Transcatheter bilateral superselective arterial embolization, a minimally invasive method for persistent hematuria in elderly and comorbid patients with bladder and prostate cancer

Objective: In this article, we aimed to share our experience with superselective vesical and prostatic artery embolization applied by transarterial microcatheter method as a treatment option for recurrent resistant hematuria due to bladder and prostate cancer in elderly and comorbid patients. Materials and Methods: Bilateral transarterial microcatheter method was used for superselective vesical or prostatic artery embolization in 10 patients whose follow-up treatment was continued in our clinic with macroscopic hematuria due to bladder and prostate cancer diagnoses and could not be treated with other palliative and radical surgical methods due to comorbidity and high surgical operative risk. Before and after embolization treatment; hemoglobin (Hb) and hematocrit (Hct) values of the patients, the amount of transfusion of blood and blood products, postoperative complications, urethral foley catheter removal times and patient satisfaction were evaluated. The patients were followed up with controls intermittently for an average of 15 months. Results: The mean age of the patients included in the study was 77.5 (69-86) years. The average hemoglobin value before and after the embolization procedure was 8,16 mg/dL and 9,48 mg/dL, respectively. The average hematocrit value before and after the embolization procedure was 25,5 and 30,4 , respectively. The average amount of blood products (erythrocyte suspension) transfusion was 2.1 (1-3) units before the procedure, and there was no need for blood transfusion in the follow-up after the procedure. The urethral catheters of all patients were removed on the 5th day (3-7 days) after the urine color became completely clear. There were no major complications, recurrent urethral catheterization or mortality, morbidity related to the treatment after the embolization procedure. Conclusion: Superselective vesical and prostatic artery embolization treatment applied by transarterial microcatheter method is an effective and reliable alternative in the case of resistant hematuria due to bladder or prostate cancer that cannot be controlled with other palliative methods due to the high risk of anesthesia in elderly patients with comorbidities. Keywords: persistent hematuria, bladder cancer, superselective vesical artery embolization

Peripheral AVMS pre-operative embolization using plug and push technique with low-density NBCA/LIPIODOL can be used in high-flow feeding arteries at Hue Central Hospital, Vietnam: a case report

Purpose: The aim of this study was to report our experience in one casepre-operative embolization of high-flow peripheral arteriovenous malformations (AVMs) using plug and push technique with low-density NBCA/LIPIODOL. Case presentation: A patient 26 years old man hospitalized at Hue Central Hospital, Vietnam with big pulsatile mass at right femoral above the knee. Doppler ultrasound showed a mass with high systolic and diastolic velocities. Patient felt discomfort and he has a desire to resolve this condition. Angiogram showed a large and high-flow arteriovenous malformation type IV according to Yakes classification. A multidisciplinary discussion was required between surgeon and interventionist because of the high risk of in-operative hemorrhage. Patient was treated with low-density NBCA/LIPIODOL 12.5% embolic agents by transarterial approach using plug and push technique before surgical excision. Results: Technical success was achieved in this patient. Complete devascularization was obtained and surgical excision was performed at 4 days after embolization procedure. Non-target NBCA/LIPIODOL embolization was not observed. Conclusions: Embolization using plug and push technique with low-density NBCA/LIPIODOL is an promising and interesting option for management of peripheral high-flow AVMs either pre-operatively or as a single treatment.

Embolization of the false lumen using IMPEDE-FX embolization plugs as part of treatment of an infrarenal post-dissection aneurysm: a case report

Background This case report demonstrates the value of IMPEDE-FX plugs in an embolization procedure of a false lumen of an infrarenal post-dissection aneurysm. Case presentation A 69-year-old patient was treated with mitral valve replacement, complicated by a Stanford type-A dissection. After 9 years he presented with an enlarging infrarenal post-dissection aneurysm. The false lumen was embolized using multiple IMPEDE-FX plugs as part of the treatment in addition to embolization of the inferior mesenteric artery and overstenting of the re-entry in the right iliac artery. At 15 months the CTA showed a fully thrombosed false lumen and remodeling of the true lumen. Conclusions The false lumen of an infrarenal post-dissection aneurysm can successfully be embolized using IMPEDE-FX embolization plugs as part of the treatment strategy. Prospective trials on patients with non-thrombosed false lumina are indicated.

Preoperative embolization of high-flow peripheral AVMs using plug and push technique with low-density NBCA/Lipiodol

Arteriovenous malformations (AVMs) embolization is considered as a promising option either its single treatment or in combination with surgery, and the use of low-density N-butyl cyanoacrylate (NBCA)/Lipiodol is acceptable mixture agents but its application should be performed by experienced endovascular teams. We describe a successful case preoperative embolization of high-flow AVMs with low-density NBCA/Lipiodol. A 26-year-old male patient was hospitalized with a big pulsatile mass at the right thigh. Doppler ultrasound showed a mass with high systolic, and diastolic velocities coming from the right superficial femoral artery. Angiogram showed a large and high-flow AVM type IV, according to Yakes classification. Low-density NBCA/Lipiodol 12.5% were performed to obstruct all the nidus and feeding arteries. Extirpation surgery was implemented 4 days after the complete embolization procedure.

Environmental sustainability in neurointerventional procedures: a waste audit

BackgroundOperating rooms contribute between 20% to 70% of hospital waste. This study aimed to evaluate the waste burden of neurointerventional procedures performed in a radiology department, identify areas for waste reduction, and motivate new greening initiatives.MethodsWe performed a waste audit of 17 neurointerventional procedures at a tertiary-referral center over a 3-month period. Waste was categorized into five streams: general waste, clinical waste, recyclable plastic, recyclable paper, and sharps. Our radiology department started recycling soft plastics from 13 December 2019. Hence, an additional recyclable soft plastic waste stream was added from this time point. The weight of each waste stream was measured using a digital weighing scale.ResultsWe measured the waste from seven cerebral digital subtraction angiograms (DSA), six mechanical thrombectomies (MT), two aneurysm-coiling procedures, one coiling with tumour embolization, and one dural arteriovenous fistula embolization procedure. In total, the 17 procedures generated 135.3 kg of waste: 85.5 kg (63.2%) clinical waste, 28.0 kg (20.7%) general waste, 14.7 kg (10.9%) recyclable paper, 3.5 kg (2.6%) recyclable plastic, 2.2 kg (1.6%) recyclable soft plastic, and 1.4 kg (1.0%) of sharps. An average of 8 kg of waste was generated per case. Coiling cases produced the greatest waste burden (13.1 kg), followed by embolization (10.3 kg), MT (8.8 kg), and DSA procedures (5.1 kg).ConclusionNeurointerventional procedures generate a substantial amount of waste, an average of 8 kg per case. Targeted initiatives such as engaging with suppliers to revise procedure packs and reduce packaging, digitizing paper instructions, opening devices only when necessary, implementing additional recycling programs, and appropriate waste segregation have the potential to reduce the environmental impact of our specialty.
