Impaired consciousness and unilateral limb movement due to acute limb ischemia complicated by acute cerebral infarction: A case report.

RATIONALE: The symptoms of impaired consciousness and unilateral motor impairments are a perfect scenario for cerebral infarction, and a physician can easily miss the findings of limb ischemia on the patient paralyzed side even if acute limb ischemia (ALI) occurs on that side. The purpose of this case report is to reiterate the need to suspect ALI in patients with impaired consciousness who cannot complain of symptoms such as abnormal limb paresthesia or pain. PATIENT CONCERNS: An 89-year-old woman with impaired consciousness and motor impairment of the left upper and lower extremities was transported to our hospital. DIAGNOSES: Brain magnetic resonance imaging showed a suspected cerebral infarction in the posterior circulation; contrast-enhanced computed tomography showed occlusion of the left axillary artery and left femoral artery; and ultrasonography showed occlusion of the right popliteal artery. INTERVENTIONS: Cerebral angiography was performed simultaneously with surgical thrombectomy to treat the ALI. Mechanical thrombectomy was not performed for cerebral infarction. OUTCOMES: Although motor impairment of the left upper and lower extremities persisted, the patient successfully underwent limb salvage. LESSONS: Both cerebral infarction and ALI require early diagnosis and treatment. This rare case of cerebral infarction complicated by ALI emphasizes the need to avoid missing the signs of ALI in patients with impaired consciousness.

Suturing Fenestration of the Left Subclavian Artery Orifice in Frozen Elephant Trunk Procedure.

The frozen elephant trunk (FET) procedure enables easier replacement of the entire aortic arch because it does not require reaching the distal part of the left subclavian artery (LSCA). However, it requires additional management for reconstruction of the LSCA, which is associated with bleeding events. However, the fenestrated FET technique confers a risk of endoleakage from the fenestration site. We report our unique novel technique in which the proximal side of the hybrid stent graft is cut into V-shape around the subclavian artery and sutured continuously around the orifice of the subclavian artery during aortic stump fixation.

Ruptured Valsalva Sinus Aneurysm with Ventricular Septal Defect and Double-Chambered Right Ventricle without Heart Failure: A Case Report.

Valsalva sinus aneurysm and double-chambered right ventricle are both rare congenital cardiac anomalies. Ventricular septal defect may be present in approximately 50%-60% of patients with Valsalva sinus aneurysm or approximately 70%-80% of patients with double-chambered right ventricle. However, Valsalva sinus aneurysm, double-chambered right ventricle, and ventricular septal defect rarely coexist in the same patient. As these diseases progress, patients often complain of symptoms of heart failure, due to the shunt flow. The case of a patient with Valsalva sinus aneurysm, double-chambered right ventricle, and ventricular septal defect without symptoms of heart failure had never been reported until now.

Efficacy of a newly modified technique for distal limited open stenting in octogenarians with aortic arch aneurysm.

OBJECTIVE: We assessed the efficacy of distal limited open stenting procedure in octogenarians with distal aortic arch aneurysm. METHODS: During the last 5 years, 24 patients underwent distal limited open stenting. Mean patient age was 81.6 ± 2.5 years, ranging from 80 to 90 years. The hemicircumference of the anterior surface of the arch around the left common carotid artery was obliquely incised, and a J-Graft Open Stent (Japan Lifeline Co, Ltd, Tokyo, Japan) was inserted into the descending aorta. During open stenting, circulatory arrest was induced at a rectal temperature of 28°C without any cerebral perfusion. As soon as the proximal side of the stent graft and aortic incision were concomitantly sutured, rapid rewarming was initiated through heated blood perfusion. RESULTS: The durations of circulatory arrest, aortic crossclamping, cardiopulmonary bypass, the overall operation, postoperative mechanical ventilation, and hospital stay were 17.0 minutes, 27.8 minutes, 106.1 minutes, 167.6 minutes, 11.0 hours, and 13.9 days, respectively. The in-hospital mortality was 0%. There were no incidences of brain damage, renal failure, or respiratory failure. At the time of this study, 21 patients were doing well and visiting the outpatient clinic, and 19 scored more than 20 points on the Mini-Mental State Examination, indicating no development of dementia. The actuarial survival at 5 years was 82.4%. CONCLUSIONS: This unique technique is safe and effective. It is a very attractive procedure that can contribute to maintaining a good long-term quality of life for octogenarians with distal aortic arch aneurysm.

Efficacy of limited proximal arch replacement for type A acute aortic dissection with critical complications.

OBJECTIVE: We assessed the efficacy of limited proximal arch replacement for type A acute aortic dissection (AAD) with critical complications. METHODS: Sixty-four patients with average age of 64.5 ± 13.0 years, who were intubated prior to arriving at hospital due to cardiopulmonary arrest, cardiac tamponade, or vital organ mal-perfusion, were divided into two groups: group PA consisted of 52 patients undergoing proximal arch repair with mild hypothermic circulatory arrest; group TA consisted of 12 patients who underwent total arch replacement with moderate hypothermia and selective cerebral perfusion. RESULTS: The intimal tear on the distal side of the left subclavian artery was not excised in 11 patients (21.2 %) of group PA. The intimal tear was excised in all patients in group TA. The durations of cerebral protection (PA, 18.7; TA, 70.3 min), cardiopulmonary bypass (PA, 121.5; TA, 206 min), and overall operation (PA, 181.8; TA, 403.8 min) were significantly shorter in group PA. The incidence of postoperative brain damage was significantly lower in group PA (9.6 %) than in group TA (33.3 %). The mortality rate was significantly lower in group PA (5.8 %) than in group TA (58.3 %). Distal arch to descending aortic replacement was required in four patients of group PA during follow-up period. There were no complications or mortality during the reoperation. The actuarial survival rate at 10 years was significantly better in group PA (66.5 %) than in group TA (25 %). CONCLUSION: Limited proximal arch repair is suitable for high-risk patients with AAD, despite no excision of the intimal tear.
