Mehmet Burak Çildağ,Mustafa Gök,Tuğba Öztürk,Ömer Faruk Kutsi Köseoğlu 대한혈관외과학회 2023 Vascular Specialist International Vol.39 No.3
Osler-Weber-Rendu syndrome (OWR) is an autosomal dominant disorder characterized by recurrent epistaxis, mucocutaneous or visceral telangiectasias, and arteriovenous malformations in the lungs, liver, brain, and gastrointestinal tract. Hepatic artery aneurysms (HAAs) can also occur in OWR patients. HAAs are the second most common type of visceral artery aneurysm, and mortality rates are high owing to the lack of a tamponade effect. Anatomical variations of the celiacomesenteric vasculature are common, and the most common variation is that of the right hepatic artery originating from the superior mesenteric artery (SMA). We present the endovascular treatment of a patient with OWR and an aberrant right HAA originating from the SMA, with coil embolization and stent grafting. Giant HAAs can be treated endovascularly. However, stent graft placement should be reconsidered because of the need for antithrombotic medication, which may increase the incidence of epistaxis attacks in that patient group.

Purpose: This study investigated the effectiveness of major salivary gland ultrasonography (MSGUS) using a new grading system and shear wave elastography (SWE) in evaluating the major salivary glands of patients with Sjögren syndrome (SjS). Methods: This prospectively-designed cross-sectional study included 49 SjS patients and 49 healthy controls. Major salivary glands were examined with gray-scale ultrasonography and SWE. A new grading system for salivary glands was developed using MSGUS findings. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of MSGUS and shear wave velocity (SWV) values were investigated. The MSGUS grading system and SWV values were evaluated together by logistic regression analysis. A cutoff value of SWE for salivary glands was determined. Results: The sensitivity, specificity, PPV, and NPV of MSGUS were 69.4%, 73.5%, 72.3%, and 70.6% for the submandibular gland and 69.4%, 65.3%, 66.7%, and 68.1% for the parotid gland, respectively. The mean SWV values of the parotid and submandibular glands were significantly higher in SjS patients than in controls (P<0.05). The sensitivity, specificity, PPV, and NPV for the submandibular gland (cutoff, 1.95 m/s) and the parotid gland (cutoff, 2.39 m/s) were 69.4%, 52%, 59.1%, and 63% and 82.7%, 83.7%, 83.5%, and 82.8%, respectively. Adding SWE to the parotid gland grading system increased the sensitivity and specificity (sensitivity, 82.7%; specificity, 83.7%). Conclusion: Evaluating the salivary glands using MSGUS with a new grading system and SWE may contribute to the diagnosis of SjS. The combination of MSGUS and SWE may be a promising tool for diagnosing SjS.
