Modified Isolation Selective Cerebral Perfusion Technique for Intracardiac Disease with Mobile Atheroma.

Isolation selective cerebral perfusion (ISCP) technique is reportedly an effective method for preventing brain complications during the treatment of arch aneurysms. Here we present the case of a patient with intracardiac disease complicated by mobile atheroma in the proximal aorta. In this patient, not only the arterial cannulation of the ascending aorta might have posed a high risk of brain stroke but also the original ISCP technique could not be applied. We applied the ISCP technique for non-aortic disease without using circulatory arrest to prevent aortogenic brain embolism. The patients who underwent treatment using this technique were discharged without neurologic complications.

Thoracic Endovascular Aortic Repair on Zone 2 Landing for Type B Aortic Dissection.

BACKGROUND: Although thoracic endovascular aortic repair (TEVAR) is an effective treatment for both complicated and uncomplicated type B aortic dissection (TBAD), the occurrence of retrograde type A aortic dissection (RTAD) after TEVAR could be a disastrous complication. The aim of this study was to examine the safety of zone 2 TEVAR in the treatment of acute and subacute TBAD. METHODS: A Relay stent graft (SG) was placed proximally beyond the left subclavian artery (LSA) as zone 2 TEVAR for complicated or uncomplicated TBAD. LSA was preserved by physician-modified fenestrated TEVAR (F-TEVAR) if anatomically possible or by surgical reconstruction of debranching TEVAR (D-TEVAR) if necessary. Otherwise, LSA was simply covered. Changes in the aortic diameters after TEVAR were evaluated using CT scanning. RESULTS: Between 2013 and 2017, 22 patients (mean age: 63 ± 14 years; 16 males) with TBAD were treated with zone 2 TEVAR. Emergency TEVAR was performed in 9 patients (41%) for complicated TBAD, and elective TEVAR was performed in 13 patients (59%) for uncomplicated TBAD in subacute phases. LSA was preserved in 16 patients via 15 F-TEVAR and 1 D-TEVAR and intentionally covered in 6 patients on emergency TEVAR. Elective TEVAR succeeded in the preservation of LSA flow in all patients (emergency 33% vs. elective 100%; P < 0.01). There were no TEVAR-related complications such as stroke, spinal cord ischemia, and RTAD. Thirty-day mortality was 0%. Aortic remodeling as the expansion of true lumen and shrinkage and complete thrombosed occlusion of false lumen were prominent at the level of SG placement 12 months after TEVAR. During the follow-up period, stent-induced new entry at the distal edge of the SG occurred in 1 patient (4%); however, there was no case of aorta-related mortality. CONCLUSIONS: Zone 2 TEVAR for acute and subacute TBAD might be promising for the prevention of RTAD.

Acute gastric volvulus associated with wandering spleen in an adult treated laparoscopically after endoscopic reduction: a case report.

A 43-year-old female was referred to our hospital for sudden onset of abdominal pain, fullness, and vomiting. Physical examination revealed abdominal distension with mild epigastric tenderness. Abdominal radiography showed massive gastric distension and plain computed tomography (CT) a markedly enlarged stomach filled with gas and fluid. A large volume of gastric contents was suctioned out via a nasogastric (NG) tube. Contrast-enhanced CT showed a grossly distended stomach with displacement of the antrum above the gastroesophageal junction, and the spleen was dislocated inferiorly. Upper gastrointestinal (GI) series showed the greater curvature to be elevated and the gastric fundus to be lower than normal. Acute mesenteroaxial gastric volvulus was diagnosed. GI endoscopy showed a distortion of the gastric anatomy with difficulty intubating the pylorus. Various endoscopic maneuvers were required to reposition the stomach, and the symptoms showed immediate and complete solution. GI fluoroscopy was performed 3 days later. Initially, most of the contrast medium accumulated in the fundus, which was drawn prominently downward, and then began flowing into the duodenum with anteflexion. Elective laparoscopic surgery was performed 1 month later. The stomach was in its normal position, but the fundus was folded posteroinferiorly. The spleen attached to the fundus was normal in size but extremely mobile. We diagnosed a wandering spleen based on the operative findings. Gastropexy was performed for the treatment of gastric volvulus and wandering spleen. The patient remained asymptomatic, and there was no evidence of recurrence during a follow-up period of 24 months. This report describes a rare adult case of acute gastric volvulus associated with wandering spleen. Because delay in treatment can result in lethal complications, it is critical to provide a prompt and correct diagnosis and surgical intervention. We advocate laparoscopic surgery after endoscopic reduction because it is a safe and effective procedure with lower invasiveness.
