Early surgical resection for cardiac myxoma is necessary because it may frequently cause cerebral infarction. However the optimal surgical timing for the disease is controversial because the acute phase of infarction may induce intracranial hemorrhage. An 82-year-old woman referred to our hospital because of unconsciousness and right hemiparesis. MRI showed infarction in the left middle cerebral artery area and UCG revealed a left atrial mass. The fourth day after the onset, brain CT showed hemorrhagic infarction and MRI showed new infarction. There was no enlargement of the hemorrhagic focus on brain CT and the patient underwent surgery on the fifth day after the onset. The postoperative course was uneventful. Despite the existence of hemorrhagic infarction, open heart surgery may save patients with cerebrovascular event.

Central diabetes insipidus (CDI) is a disease that caused by insufficient or no anti-diuretic hormone (ADH) secretion from the posterior pituitary, which results in an increase in urine volume. CDI is controlled with ADH supplementation thereby reducing urine output and correcting electrolyte imbalance. However, reports on perioperative management for CDI patient are scarce, especially for patients who underwent cardiac surgery. We herein report our experience of the management of a CDI patient who underwent surgery for valvular heart disease.

The case is a 72-year-old woman who developed secondary CDI after pituitary tumor removal. She had been controlled with orally administered desmopressin acetate hydrochloride. She underwent aortic valve replacement and mitral valve repair for severe aortic, and moderate mitral regurgitation. Immediately after surgery, we started vasopressin div, which yielded good urine volume control. However, once we started to switch vasopressin to oral desmopressin administration, the control became worse. We thus made a sliding scale for subcutaneous injection of vasopressin every 8 h according to the amount of urine output, which resulted in good control. Overlapping administration of vasopressin and oral desmopressin between postoperative day 12 and 17 resulted in successful transition. The patient was discharged with oral desmopressin administration. Management with sliding scale for vasopressin subcutaneous injection after surgery was useful in controlling a CDI patient who underwent major cardiac surgery.

Purpose: To clarify the family-perceived usefulness of a pamphlet for families of imminently dying patients. Methods: Physicians and/or nurses provided medical and practical information about the dying process using a pamphlet for families of imminently dying patients. We surveyed family members 6 months after the death of the patient about the perceived usefulness. Results: We sent out a questionnaire to 325 bereaved, and obtained an answer from 260 (response rate: 85%). Overall, 81% reported the pamphlet to be “very useful” or “useful”. The experience reported by the bereaved included: “Helped me to understand the dying process” (84%); “Helped me to understand how symptoms and changes occur” (76%), “Useful in preparation for patient's death“ (75%), “Helped me to understand the physical conditions of the patient” (75%), “Helped me to know what I can do for the patient” (74%). Conclusion: “A pamphlet for families of imminently dying patients” may be useful for members of an imminently dying patient's family.

Objective: To examine the association between the mobilization level during intensive care unit (ICU) admission and independence in activity of daily living (ADL), defined as Barthel Index (BI)≥70. Methods: This was a post-hoc analysis of the EMPICS study involving nine hospitals. Consecutive patients who spend >48 hours in the ICU were eligible for inclusion. Mobilization was performed at each hospital according to the shared protocol and the highest ICU mobility score (IMS) during the ICU stay, baseline characteristics, and BI at hospital discharge. Multiple logistic regression analysis, adjusted for baseline characteristics, was used to deter-mine the association between the highest IMS (using the receiver operating characteristic [ROC]) and ADL. Results: Of the 203 patients, 143 were assigned to the ADL independence group and 60 to the ADL dependence group. The highest IMS score was significantly higher in the ADL independence group than in the dependence group and was a predictor of ADL independence at hospital discharge (odds ratio, 1.22; 95% confidence interval, 1.07–1.38; adjusted p=0.002). The ROC cutoff value for the highest IMS was 6 (specificity, 0.67; sensitivity, 0.70; area under the curve, 0.69). Conclusion These results indicate that, in patients who were in the ICU for more than 48 hours, that patients with good function in the ICU also exhibit good function upon discharge. However, prospective, multicenter trials are needed to confirm this conclusion.

Vertebral artery stump syndrome (VASS) is a rare condition that can cause posterior circulation ischemic stroke due to occlusion of the ipsilateral vertebral artery (VA) orifice, resulting in blood flow stagnation and embolus formation. Although there is no established treatment for this condition, we observed 3 cases of VASS out of 326 acute ischemic stroke cases at a single institution from April 2021 to October 2022. Despite the best possible antithrombotic treatment, all 3 patients had recurrent ischemic strokes. One patient underwent drug-eluting stenting of the VA orifice to relieve occlusive flow. The other 2 patients received coil embolization, which resulted in the disappearance of their culprit collateral flow. None of the patients had recurrent ischemic strokes after endovascular intervention. Based on our observations, stenting and coil embolization are effective methods for preventing future recurrences of VASS.

This case report aimed to evaluate the efficacy of applying VIABAHN endoprosthesis at the dissection re-entry of the right renal artery after thoracic endovascular aortic repair (TEVAR) in a patient with a chronic type B dissected thoracoabdominal aneurysm. A 78-year-old man was given a diagnosis of type B aortic dissection 5 years ago and underwent a successful TEVAR operation. Two years later, he developed complications such as chronic expanding aortic dissections ; thus, he underwent a second endovascular repair. Enhanced computed tomography (CT) scanning at the five-year follow-up after initial endovascular repair showed a 58-mm diameter thoracoabdominal dissected aneurysm. It also showed an apparent entry point dissection arising from the lower thoracic aorta and a re-entry point at the base of the right renal artery. Although the right renal artery was affected by the dissecting false lumen, all other abdominal branches were intact. He was treated with VIABAHN via occlusion of the re-entry of the dissection and reconstruction of the right renal artery. The patient recovered uneventfully and was discharged 10 days after the operation. Postoperative enhanced CT scanning showed that the aortic false lumen was completely thrombosed, and the right renal arterial flow had significantly improved. Although TEVAR is the standard treatment in acute complicated type B dissections, its role in chronic type B dissections remains controversial. Our technique of using VIABAHN for the reconstruction of the right renal artery showed promising results for patients with chronic type B dissections.

We present a case of redo aortic valve replacement (AVR) in a 71-year-old man with a Lillehei-Kaster valve implanted 42 years prior. The patient initially underwent AVR and open mitral commissurotomy procedures for aortic regurgitation complicated with mitral stenosis in 1978 at the age of 29. Thereafter, he was followed at our outpatient clinic and treated without anticoagulant therapy for the initial two decades of the postoperative period. During the long-term follow-up, the mean pressure gradient remained between 40 and 60 mmHg and there were no adverse events noted before occurrence of heart failure triggered by tachycardia and pneumonia. Following improvement of heart failure, redo AVR was performed. There was no structural damage, thrombosis, or Lillehei-Kaster valve opening restrictions, though severe pannus growth on the left ventricle side was observed, which was thought to be the cause of the increased pressure gradient. This is the first known report of redo AVR after many years in a patient who underwent Lillehei-Kaster valve implantation. Furthermore, no other study has noted findings regarding pressure gradient change during the long-term follow-up period in such cases.
