Isolated left vertebral artery (ILVA) is one of the most frequent vertebral abnormalities. When performing thoracic endovascular aortic repair (TEVAR), the ILVA may have to be closed depending on the position of the stent graft; in these cases, the decision to reconstruct the ILVA depends on the state of cerebral blood flow. Here, we report a case of a 68-year-old male, in whom the Willis arterial circle was incomplete; we therefore performed a reconstructive method during zone 2-landing TEVAR that ensured ILVA and left subclavian artery blood flow without the use of artificial vessels. Only one supraclavicular incision was required for reconstruction. This method has some procedural difficulties; however, it does not use artificial blood vessels and can be performed with a single incision.

This case report details the management of a 79-year-old man who developed massive postoperative pneumothorax following redo coronary artery bypass grafting due to severe lung adhesions. We successfully treated the patient using veno-venous extracorporeal membrane oxygenation without femoral cannulation, allowing for early rehabilitation initiation. Veno-venous extracorporeal membrane oxygenation is a reasonable option for cases of severe respiratory failure due to pneumothorax with lung destruction caused by re-sternotomy during re-do cardiac surgery.

Nonbacterial thrombotic endocarditis (NBTE) on the aortic valve involves fibrin and platelet aggregate formation, potentially leading to embolic events. We present a case of NBTE on the aortic valve following coronary angiography (CAG) in a 54-year-old man with multiple comorbidities. Surgical thrombectomy was performed owing to acute cerebral infarcts. This case highlights the significance of considering that mechanical trauma from catheterization during CAG can trigger thrombus formation.

Minimally invasive cardiac surgery (MICS) is a helpful technique when you have to perform cardiac surgery for a patient with chronic tracheostomy. To avoid risk of sternal wound infection and mediastinitis, MICS may be a safer approach than medial sternotomy for tracheostomy patients. Here, we present a septuagenarian male patient. He was diagnosed with acute heart failure due to mitral valve regurgitation (MR) with such deteriorating general condition that a tracheostomy was necessary. After transfer to our hospital, Mitral Clip was performed for his MR, after which, he developed a fever from suspected infectious endocarditis (IE). We ultimately performed minimally invasive mitral valve plasty to eliminate the MR and treat the IE, without post operational complications.

<h4>Background</h4>No study has examined the association of the calcification of abdominal artery orifices with nonocclusive mesenteric ischemia (NOMI) in dialysis patients undergoing cardiac surgery. Thus, this study aimed to determine whether calcification of abdominal blood vessel orifices in hemodialysis patients may be a risk factor for NOMI and examine the long-term survival of dialysis patients after undergoing cardiac surgery.<h4>Methods</h4>From April 2014 to September 2020, 100 dialysis patients underwent cardiac surgery at our hospital. The calcification of the celiac artery (CA) and superior mesenteric artery (SMA) was evaluated by computed tomography, and the degree of orifice stenosis was graded as follows: patent, 0; partial occlusion, 1; and complete occlusion, 2.<h4>Results</h4>Eight patients experienced NOMI, and all of them died. SMA calcification scores were not significantly different between the NOMI and non-NOMI groups (1.38±0.52 vs. 1.13±0.69; P = 0.247). However, the average CA orifice calcification score was significantly greater in the NOMI group than in the non-NOMI group (1.63±0.52 vs. 1.15±0.65; P = 0.039), and the SMA+CA orifice calcification scores were significantly different between the groups (3.00±0.76 vs. [non-NOMI] 2.25±1.18; P = 0.028). In all patients, the 30-day and in-hospital mortality rates were 13% and 18%, respectively. All patients were completely followed up with a mean follow-up period of 604±585 days. Kaplan-Meier survival curves showed that patients with SMA and CA calcification tended to have a shorter overall survival than patients without calcification; however, no significant difference was noted.<h4>Conclusions</h4>The calcification of CA and/or SMA orifices was associated with postoperative NOMI and poor long-term survival among dialysis patients undergoing cardiac surgery.

Neuron-specific-enolase is used as a marker of neurological prognosis after cardiopulmonary resuscitation. It is also present in red blood cells and platelets. It is not known whether hemolysis increases the values of neuron-specific-enolase enough to clinically affect its interpretation in critically ill patients who are to be introduced to veno-arterial extracorporeal oxygenation. In this study, we examined the relationships among neuron-specific-enolase and hemolysis indicators such as free hemoglobin and lactate dehydrogenase after the introduction of veno-arterial extracorporeal oxygenation. Of the 91 patients who underwent veno-arterial extracorporeal membrane oxygenation in our hospital from January 1, 2018, to February 24, 2021, 68 patients survived for more than 24 h. Of these, 14 patients who were categorized into the better cerebral performance categories (1-3) and 19 patients who were categorized into the poor neurological prognosis category (4) were included. After the introduction of veno-arterial extracorporeal membrane oxygenation, neuron-specific-enolase was markedly higher in the poor neurological prognosis group than in the good neurological prognosis group (41.6 vs. 92.0, p = 0.04). A significant positive correlation was revealed between neuron-specific-enolase and free hemoglobin in the good neurological prognosis group (rs = 0.643, p = 0.0131). A similar relationship was observed for lactate dehydrogenase and neuron-specific-enolase in both the conscious (rs = 0.737, p = 0.00263) and non-conscious groups (rs = 0.544, p = 0.0176). When neuron-specific-enolase is used as a marker for neuroprognostic evaluation, an abnormally high value is likely to indicate the lack of consciousness, whereas a lower elevation should be interpreted with caution, taking into account the effects of hemolysis.

An 81-year-old man was transferred to our hospital for a ruptured infected descending aortic aneurysm. An emergency thoracic endovascular aortic repair was performed, but a computed tomography scan 7 days later revealed an aortoesophageal fistula. The establishment of extracorporeal circulation using the femoral artery and utilization of the omentum was considered difficult. We performed bilateral axillofemoral bypass followed by descending aortic resection and esophagectomy. However, the patient's circulatory insufficiency worsened, and he died on the 18th postoperative day. In the treatment of aortoesophageal fistula, bilateral axillofemoral bypass is not recommended as an alternative to descending aortic replacement.

Pulmonary valve stenosis and regurgitation can occur in the distant stages after intracardiac repair of tetralogy of Fallot (TOF). Aortic regurgitation (AR) can also occur, although it is rare in postoperative patients. However, there are few reports of simultaneous replacement of the pulmonary and aortic valves in young patients after intracardiac repair of TOF, and there are no clear guidelines for selecting a valve prosthesis in such patients. We report a case of severe pulmonary valve stenosis and regurgitation with severe AR 38 years after the TOF operation, in which urgent double valve replacement and right ventricular outflow tract patching were performed with a mechanical valve in the aortic valve position and a bioprosthetic valve in the pulmonary valve position, with a successful outcome.
