Swallowing-induced Paroxysmal Atrial Tachycardia Causes Weight Loss and Fainting During Mealtime: A Case Report and Literature Review.
Swallow or deglutition syncope is an unusual disorder. We herein report an 80-year-old man with paroxysmal atrial tachycardia induced by swallowing, causing syncope. Initially, we suspected a digestive disorder and found no significant findings. ⋯ The patient was treated with antiarrhythmic drugs and catheter ablation. The mechanism underlying swallowing-induced tachycardia presumably involves mechanical stimulation of the esophagus and autonomic nervous system effects. However, few cases have been reported, and the exact mechanism remains unclear.

Endoscopic injection sclerotherapy (EIS) for esophagogastric varices (EGV) was attempted for a 29-year-old man with extrahepatic portal vein obstruction. However, pipeline varices characterized by a large blood flow volume were present, and the sclerosant did not accumulate sufficiently in them. ⋯ Since a reduction in the intravariceal blood flow was achieved by preceding TIO, effective injection of sclerosant into the vessels was possible. For pipeline varices difficult to treat endoscopically, combination therapy with TIO may be effective.

Massive hemoptysis is a fatal complication associated with pulmonary tuberculosis (TB). It can lead to severe respiratory failure. Extracorporeal membrane oxygenation (ECMO) is a life-saving technology that is rarely indicated for bleeding disorders. ⋯ Transcatheter artery embolization was successfully performed with venovenous ECMO support. The hemostatic procedure allowed concomitant anticoagulant use, and neither bleeding nor thrombotic complications occurred throughout the clinical course. Administering the appropriate hemostatic procedure with subsequent management, including anticoagulant therapy, supported ECMO application in a case of bleeding.

Bow hunter's stroke is a rare cause of vertebrobasilar infarction. There is no consensus regarding the optimal treatment. We herein report a case of bow hunter's stroke successfully treated by endovascular treatment. ⋯ Dynamic angiography revealed thrombus formation and hypoperfusion of the right vertebral artery upon head rotation to the left. Endovascular parent artery occlusion of the right vertebral artery was performed, and there was no recurrence at follow-up MRI. Endovascular parent artery occlusion might be a useful treatment for bow hunter's stroke.

Objective We retrospectively analyzed the prevalence and clinical features of splenic infarctions in patients with Philadelphia chromosome-negative myeloproliferative neoplasms (Ph- MPNs). Patients Patients diagnosed with essential thrombocythemia (ET), polycythemia vera (PV), prefibrotic/early primary myelofibrosis (pre-PMF), or PMF from January 1996 to October 2020 in Chungnam National University Hospital, Daejeon, Korea, were reviewed. Results A total of 347 patients (143 ET, 129 PV, 44 pre-PMF, and 31 PMF patients; 201 men and 146 women) with a median age of 64 (range 15-91) years old were followed up for a median of 4.7 (range 0.1-26.5) years. ⋯ Conservative treatment adequately controlled the symptoms; no serious complications were noted in any patient. Conclusion Splenic infarctions occurred most frequently in patients with PMF; it was rare in patients with ET. The clinical courses were generally mild.
