Vertebro-Vertebral Fistula Occlusion Using a Woven EndoBridgeTM-Device.

Vertebro-vertebral fistulas (VVFs) are vascular lesions that may develop after trauma or spontaneously in association with connective tissue disorders. We present a rare case of a post-traumatic VVF in a young patient presenting with a painless swelling and a bruit in her left upper neck. Digital subtraction angiography showed an arteriovenous fistula between the left vertebral artery (VA) and the vertebral venous plexus with significant steal phenomenon. Endovascular therapy was performed using a Woven EndoBridgeTM (WEB)-device combined with coils that allowed preservation of the VA. The patient fully recovered from her symptoms and follow-up imaging showed stable occlusion. In conclusion, VVFs can be effectively treated using intrasaccular flow diverters such as the WEB-device, allowing for complete and stable occlusion while preserving the parent artery.

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..

[Correct diagnostic of traumatic renal trauma is important for the treatment].

Renal trauma is injury to the kidney because of either blunt or penetrating trauma. The condition must be diagnosed quickly and correctly in order to preserve kidney function. This article describes classification, diagnostics, treatment and follow-up. It is important to do a CT-urography to classify the injury properly. The majority of the patients with renal injury can be managed conservatively. Surgical exploration is primarily for the control of haemorrhage. Complications may require additional imaging or inter-ventions. Follow-up is focused on renal function and blood pressure.

Lipomatous tumours of the face in infants: diagnosis and treatment.

PURPOSE: The aim of this review is to present the different lipomatous tumours of the face typically found in infants. Lipomatous tumours induce a diagnostic challenge due to the low frequency, and the fact that the different lipomatous tumours mimic each other. METHOD: This study developed a flowchart for use in the evaluation of these tumours, including congenital infiltrating lipomatosis of the face, lipoblastomas, and liposarcomas. RESULTS AND CONCLUSIONS: The clinical presentation, histological features, imaging characteristics and treatment options are covered. It is suggested that a careful clinical examination is followed by magnetic resonance imaging. A histological analysis is often necessary to establish a definitive diagnosis, and a core needle biopsy is preferred in regards to sampling. Surgery is the treatment of choice, and should be performed by multidisciplinary teams in highly experienced centres. Individual surgical planning is mandatory.

Perioperative blood transfusion does not decrease survival after surgical treatment of spinal metastases.

PURPOSE: To assess whether perioperative allogenic blood transfusions in patients undergoing surgical treatment for spinal metastases independently influence patient survival. METHODS: A retrospective study including 170 consecutive patients undergoing surgical treatment for spinal metastases in 2009 and 2010 at a tertiary referral center. Variables related to postoperative survival were all included in the same multivariable logistic regression analysis with either 3- or 12-month survival as the dependent variable. The independent variables were: transfusion of allogenic red blood cells, age at surgery, gender, preoperative hemoglobin, revised Tokuhashi score and no. of instrumented levels. RESULTS: Perioperative allogenic blood transfusion of 1-2 units was associated with increased 12-month survival [p = 0.049, odds ratio 2.619 (confidence interval 1.004-6.831)], but not with 3-month survival. Larger transfusion volumes did not significantly influence survival. CONCLUSION: The results of the present study support that perioperative blood transfusion of <5 units does not decrease survival in patients operated for spinal metastases. Transfusion of 1-2 units seems to be associated with increased 12-month survival. Future studies should assess if a liberal transfusion regime can be applied to this group of patients; thereby, prioritizing early postoperative mobilization.
