Ruptured Intercostal Artery Aneurysm with Radiculomedullary Branch Downstream Treated with Endovascular Stenting.

Intercostal artery aneurysms are extremely rare, and could be associated with aortic coarctation, systemic diseases like neurofibromatosis, or more rarely Marfan syndrome. They could be life-threatening when ruptured, leading to hemothorax or mediastinal hematoma. Endovascular management before or after rupture of intercostal aneurysms, should be considered. Radiculomedullary branch, especially Adamkiewicz one, emanating from intercostal artery needs special focus during endovascular management, to avoid spinal cord ischemia. We present herein the first case of a ruptured intercostal artery aneurysm with a downstream Adamkiewicz artery in a suspected Marfan patient. Aneurysmal exclusion using stent graft was the unique therapeutic option.

18-FDG PSEUDOTUMORAL LESION WITH QUICK FLOWERING TO A TYPICAL LUNG CT COVID-19.

As coronavirus pandemic continues to spread over the world, physicians have to be aware of atypical features of COVID-19 pneumonia. We report the case of a 78-year-old man presenting with pseudo-tumoral focal lesion of the left lung which switched shortly to severe and diffuse COVID-19 induced pneumonia. Nuclear medicine physicians and radiologists should be careful of some misleading hypermetabolic aspects mostly in asymptomatic patients.

Right Colectomy with Absorbable Mesh Repair as a Salvage Solution for the Management of Giant Incisional Hernia with Loss of Domain: Results of a Bicentric Study.

BACKGROUND: Incisional hernia (IH) may occur in 20% of patients after laparotomy. The hernia sac volume may be of significance, with reintegration of visceral contents potentially leading to repair failure or abdominal compartment syndrome. The present study aimed to evaluate a two-step surgical strategy comprising right colectomy for hernia reduction with synchronous absorbable mesh repair followed by definitive non-absorbable mesh repair in recurrence. METHODS: Patients operated between 2012 and 2017 at two university centers were retrospectively included. Volumetric evaluation of the IH was performed by CT imaging. RESULTS: Eleven patients were included. The mean BMI was 43 kg/m2 (23-52 kg/m2). Progressive preoperative pneumoperitoneum was performed in 82% of patients, with complications in 22%. The mean volumetric ratio of the volume of the hernia to the volume of the abdominal cavity was 70% (48-100%). The first parietal repair was performed using an synthetic absorbable mesh (36%), a biologic mesh (27%), or a slowly absorbable mesh (36%). No patients died as a result of the procedure. Seven (64%) patients developed grade III-IV complications, including one case of an anastomotic fistula. Recurrence occurred in eight (73%) patients after the first repair. Of these, four (50%) patients were reoperated using a non-absorbable mesh, leading to solid repair in 75% of cases. After 27 ± 18 months of follow-up, the residual IH rate was 46%. CONCLUSIONS: Right colectomy for volume reduction in IH with loss of domain potentially represents an appropriate salvage option, supporting bowel reintegration and temporary hernia repair with absorbable material.

DWI-ASPECTS (Diffusion-Weighted Imaging-Alberta Stroke Program Early Computed Tomography Scores) and DWI-FLAIR (Diffusion-Weighted Imaging-Fluid Attenuated Inversion Recovery) Mismatch in Thrombectomy Candidates: An Intrarater and Interrater Agreement Study.

BACKGROUND AND PURPOSE: We aimed to study the intrarater and interrater agreement of clinicians attributing DWI-ASPECTS (Diffusion-Weighted Imaging-Alberta Stroke Program Early Computed Tomography Scores) and DWI-FLAIR (Diffusion-Weighted Imaging-Fluid Attenuated Inversion Recovery) mismatch in patients with acute ischemic stroke referred for mechanical thrombectomy. METHODS: Eighteen raters independently scored anonymized magnetic resonance imaging scans of 30 participants from a multicentre thrombectomy trial, in 2 different reading sessions. Agreement was measured using Fleiss κ and Cohen κ statistics. RESULTS: Interrater agreement for DWI-ASPECTS was slight (κ=0.17 [0.14-0.21]). Four raters (22.2%) had a substantial (or higher) intrarater agreement. Dichotomization of the DWI-ASPECTS (0-5 versus 6-10 or 0-6 versus 7-10) increased the interrater agreement to a substantial level (κ=0.62 [0.48-0.75] and 0.68 [0.55-0.79], respectively) and more raters reached a substantial (or higher) intrarater agreement (17/18 raters [94.4%]). Interrater agreement for DWI-FLAIR mismatch was moderate (κ=0.43 [0.33-0.57]); 11 raters (61.1%) reached a substantial (or higher) intrarater agreement. CONCLUSIONS: Agreement between clinicians assessing DWI-ASPECTS and DWI-FLAIR mismatch may not be sufficient to make repeatable clinical decisions in mechanical thrombectomy. The dichotomization of the DWI-ASPECTS (0-5 versus 0-6 or 0-6 versus 7-10) improved interrater and intrarater agreement, however, its relevance for patients selection for mechanical thrombectomy needs to be validated in a randomized trial.
