[Plastic bronchitis].

Plastic bronchitis (PB) is a rare disease caused by abnormal lymphatic vessels in the thorax. These vessels drain into the bronchi creating solid casts and potential life-threatening airway obstruction. This is a case report of a 30-year-old man diagnosed with PB after several years of extensive examinations due to symptoms misconceived as non-allergic asthma. We describe the first interventional treatment in Denmark using special T2 weighed MR imaging and dynamic contrast MR lymphangiography with subsequent embolisation of abnormal lymphatic vessels in the thorax.

Embolization of the thoracic duct in patients with iatrogenic chylothorax.

Chylothorax is leakage of lymphatic fluid accumulating in the pleural cavity due to the thoracic duct's (TD) trauma or obstructions. It generally occurs as a traumatic complication after general thoracic surgery procedures (0.4%), especially after esophagectomy (4.7-8.6%). Traditionally, surgical intervention is performed if conservative management fails, but reports of high mortality (2.1%) and morbidity (38%) have led to the development of a minimally invasive percutaneous treatment method; TD embolization (TDE). The records of all patients treated for chylothorax with TDE from April 2015 to June 2019 were reviewed. Only patients with iatrogenic chylothorax were included. The outcomes measures are defined as a technical and a clinical success. A technical success, is defined as the ability to perform the embolization procedure, thereby injecting embolizing material Histoacryl with or without coils. A clinical success is defined as a complete cessation of lymphatic leakage into the pleural cavity without surgical intervention and, therefore, a cured patient. Lymphography was performed in all patients, and visualization of cisterna chyli was achieved in 14/17 patients (82.4%). Of the 17 patients included, 15 patients were successfully embolized and cured of chylothorax (88.2%). Successfully embolized patients had a median discharge time of 7 days. Most patients reported postprocedural pain, which was dealt with using conventional pain medication. TDE seems like a safe percutaneous treatment technique with a high clinical success rate in iatrogenic chylothorax patients which can be readily implemented if the clinical experience is available..

Preoperative Embolization of a Solitary Fibrous Tumor Originating from External Auditory Meatus: A Case Report with Literature Review.

Solitary fibrous tumors (SFTs) are mesenchymal, fibroblastic tumors with mostly favorable, but still unpredictable prognosis. Their rarity and occurrence at a variety of locations coupled with variable histological appearance make the diagnosis a challenge. This can be resolved by histological and immunohistochemical analysis on the histologic material eventually coupled with demonstration of NAB2-STAT6 gene fusion by next generation sequencing (NGS) analysis. Tumor removal with clear surgical margins is sufficient for complete cure in most cases. Percutaneous transcatheter embolization in well-vascularized lesions may minimize the risk of bleeding during subsequent removal. In this article we present a rare case of SFT arising from the external auditory canal and treated with preoperative endovascular arterial embolization. A literature review with focus on diagnostics and treatment of this entity in the head and neck region is following.

Gigantic Ruptured Aneurysm of the Gastroduodenal Artery Successfully Treated by Coiling.

INTRODUCTION: Visceral aneurysms are rare and a life threatening condition in the case of rupture. REPORT: A 78 year old woman presented with sudden brief loss of consciousness and complained of abdominal tenderness on examination. Computed tomography revealed a gigantic 100 × 130 × 200 mm ruptured true aneurysm of the gastroduodenal artery, which was successfully treated by endovascular coiling. Post-operative observation was uneventful and the six week follow up duplex ultrasound confirmed absence of luminal flow in the aneurysm. DISCUSSION: The treatment threshold of visceral aneurysms and treatment modalities are reviewed.

Prostate Artery Embolization for Lower Urinary Tract Symptoms in Men Unfit for Surgery.

Nearly one in three men develop lower urinary tract symptoms (LUTS) and 10% clinically progress despite medication. Transurethral resection of the prostate (TURP) is the reference standard for symptoms refractory to medical treatment. However, some patients cannot tolerate TURP for medical (e.g., comorbidity) or technical (e.g., large prostate) reasons. This study estimated the safety and effect of prostate artery embolization (PAE) in men unfit for surgery. A prospective, single-centre trial including men with LUTS or urinary retention secondary to benign prostatic hyperplasia (BPH) who were unfit for surgery. The primary objective was to treat urinary retention and LUTS. Outcome measures included International Prostate Symptom Score (IPSS), quality of life (IPSS-QoL), International Index of Erectile Function (IIEF-5), prostate volume (PV), prostate-specific antigen (PSA), peak void flow (Qmax), post-void residual (PVR), and complications. A p-value < 0.05 was considered statistically significant. Eleven consecutive patients with a mean age of 75.2 (SD ± 8.2) underwent PAE. Catheter removal was successful in 60%. IPSS-QoL improved 4.5 points (95% CI: -5.6; -3.4), and PV was reduced by 26.2 cm3 (95% CI: -50.9; -2.3). None of the remaining outcomes changed. No major complications occurred. PAE was effective and safe for LUTS and urinary retention associated with BPH in men unfit for surgery.
