Systemic sclerosis (SSc) is a collagen disease with immune abnormalities, vasculopathy, and fibrosis. Ca blockers and prostaglandins are used to treat peripheral circulatory disturbances. Chronic limb-threatening ischemia (CLTI) is a disease characterized by extremity ulcers, necrosis, and pain due to limb ischemia.

Objectives: Our goal was to evaluate postoperative patterns of collateral arteries to the spinal cord during occlusion of the segmental arteries supplying the artery of Adamkiewicz (AKA).
Methods: Between April 2011 and December 2022, a total of 179 patients underwent thoraco-abdominal aortic aneurysm repair; 141 had an identifiable AKA on preoperative multidetector computed tomography scans, 40 underwent thoraco-abdominal aortic aneurysm replacement (TAAR) and 101 underwent thoracic endovascular aortic repair (TEVAR). New postoperative collateral blood pathways invisible on preoperative contrast-enhanced computed tomography scans were identified in 42 patients (10 patients who had TAAR vs 32 patients who had TEVAR) who underwent preoperative and postoperative multidetector computed tomography scanning for AKA identification.

We encountered a 75-year-old man who underwent total arch replacement for a thoracic aortic aneurysm, then ascending aortoplasty for hemolysis due to a kinked ascending aortic graft. He presented with exhaustion and anemia 3 years later. Computed tomography revealed a large floating thrombus in the ascending aortic graft attached to the dorsal suture line.

Though the thermodynamic properties of R-1132a were investigated in several studies up to 2018, reinvestigations have been carried out in recent years. In order to contribute toward these renewed measurements, the critical parameters of R-1132a were experimentally re-determined.

Objectives: Spinal cord protection during thoracoabdominal aortic surgery is challenging for surgeons. We performed thoracoabdominal replacement using a strategy for maintaining spinal cord perfusion pressure. Here, we report our experience with this procedure and the surgical outcomes.

Methods: From January 2008 to December 2015, 159 patients underwent aortic arch surgery using innominate artery perfusion and were included in the study analysis (mean age, 71.
Objectives: There are various treatment strategies for chronic-type B aortic dissection involving the aortic arch. Our aim was to review our surgical experience in the anterolateral thoracotomy with the partial sternotomy approach for chronic-type B aortic dissection involving the aortic arch.
Methods: From January 2000 to October 2015, 39 patients underwent the single-stage open surgery for chronic-type B aortic dissection involving the aortic arch using the anterolateral thoracotomy with partial sternotomy approach.
An 85-year-old woman was hospitalized by emergency for an acute Stanford type A aortic dissection. Computed tomography showed a primary entry on the ascending aorta and pericardial effusion. Although her hemodynamics was unstable due to cardiac shock, her family wished no open surgery considering her age and frailty.

The standard surgical procedure at our institution is total aortic arch plus descending aortic replacement using anterolateral thoracotomy with partial sternotomy.

Prosthetic valve fracture is a serious complication and may arise in patient post-valve replacement. We experienced an outlet strut fracture and leaflet escape of a Bjork-Shiley convexo-concave valve. We performed an emergency redo mitral valve replacement and successfully retrieved the fractured strut and escaped leaflet from superficial femoral artery and the abdominal aorta.

The present study was designed to examine the etiology of 'smoker's paradox', especially with respect to the association with inflammation. The subjects included 528 consecutive AMI patients who were admitted within 24 hours of onset and underwent successful coronary intervention.
