Safe and favorable prognosis of thoracic endovascular aortic repair for the low-risk patients with non-acute type B aortic dissection.

Objective: Preemptive thoracic endovascular aortic repair (TEVAR) has the potential to improve the prognosis of Stanford type B aortic dissection (TBAD), however it is important to determine whether it could be safely performed as a prophylactic treatment. This study aimed to determine the short- and long-term outcomes of preemptive TEVAR for uncomplicated TBAD with a small aortic aneurysm.

Design: Retrospective multicenter analysis.

Optimal size of Frozenix for true thoracic aneurysms: is downsizing an option?

Objective: During total arch replacement (TAR) using frozen elephant trunk (FET) technique with Frozenix for true thoracic aortic aneurysm (tTAA), oversized FET tends to be chosen similar to the endovascular devise selection. However, the oversized FET is considered a risk factor for intimal injury. The appropriate size selection of FET remains insufficiently understood.

[Left Atrial Appendage Closure with Various Types of Surgical Technique and Its Results].

Background: Occlusion of the left atrial appendage( LAA) may prevent stroke in patients with atrial fibrillation. In this study, we reviewed various types of LAA occlusion techniques and results of patients underwent surgical LAA closure.

Methods: Between 2004 and 2022, 182 patients who underwent surgical LAA closure were enrolled in this study.

Safe and promising outcomes of in-hospital preoperative rehabilitation for coronary artery bypass grafting after an acute coronary syndrome.

Objective: In patients with stable hemodynamic status after an acute coronary syndrome (ACS), coronary artery bypass grafting (CABG) after preoperative investigations can provide outcomes comparable to those of emergency surgery. However, no established guidelines exist regarding the preparation period before surgery. We report the results of the use of an inpatient cardiac rehabilitation program followed by CABG after an ACS to improve post-operative outcomes and prognosis after discharge.

Spontaneous Lumbar Artery Injury Resulting in Retroperitoneal Hematoma Mimicking Abdominal Aortic Aneurysm Rupture.

A 73-year-old woman, who had previously undergone endovascular aortic repair (EVAR), developed severe back pain while shoveling snow. Preoperative computed tomography (CT) revealed marked retroperitoneal hematoma around the abdominal aortic aneurysm (AAA) with extravasation of contrast media. Intraoperative angiography demonstrated spontaneous lumbar artery injury (SLI).

Endovascular Repair for Abdominal Aortic Aneurysm Rupture With Neurofibromatosis Type 1.

Background: Neurofibromatosis type 1 (NF1), also known as von Recklinghausen disease, is a rare congenital disorder with an autosomal dominant inheritance. Severe perioperative complications owing to the congenital fragility of the vascular wall in NF1 patients have been reported. The optimal vascular surgical approach remains controversial.

Left coronary button aneurysm presenting with progressive enlargement after aortic root replacement.

Background: Aneurysmal degeneration of the coronary button after aortic root replacement using the button technique is a rare but potentially life-threatening complication. However, the appropriate management of this complication, including the indications for conservative and surgical treatment, is still unknown.

Case Presentation: Here we present a 38-year-old woman who successfully underwent surgical repair of a left coronary button aneurysm using the graft interposition technique 24 years after aortic root replacement.

Double left brachiocephalic vein in an adult patient who underwent cardiac surgery: a case report.

Background: A double left brachiocephalic vein is an extremely rare venous anomaly.

Case Presentation: Herein, we present the case of a 79-year-old woman with a double left brachiocephalic vein who underwent cardiac surgical procedures. The normal left brachiocephalic vein was patent, and the accessory left brachiocephalic vein passed across the heart and aorta in front of the pericardium and drained into the superior vena cava.

Step-by-step aortic clamping technique for safe retrieval of the elephant trunk.

Staged repair of the aortic arch and downstream aorta using the elephant trunk technique is widely accepted for extensive aortic disease. However, elephant trunk retrieval is challenging in patients with unclampable descending aorta caused by extreme aneurysmal dilation or surrounding tissue adhesion. Here, we introduce a new elephant trunk retrieval technique using the step-by-step aortic clamping in descending aortic replacement of dissecting aortic aneurysm.

Surgical repair of deep femoral artery aneurysm complicated by deep vein thrombosis and pulmonary embolism.

Isolated deep femoral artery aneurysms are rare and tend to be large at the time of diagnosis owing to their deep anatomic location. Deep femoral artery aneurysms are often complicated by rupture, with subsequent lower limb amputation. However, a large aneurysm can compress the surrounding deep femoral vein, leading to thrombosis.

Large cardiac wall hematoma with rapid growth: a case report of a potentially catastrophic complication during cardiac surgery.

Background: Rapid growth of cardiac wall hematoma is a rare but potentially fatal complication of cardiac surgery. However, its pathophysiology and optimal management remain undefined.

Case Presentation: Here we present a rare case of a large cardiac wall hematoma in the right ventricle during a thoracic aortic and valvular surgery.

[Surgical Strategy for Aortic Arch Aneurysms in Octogenarians].

Backgrounds: The purpose of this study was to evaluate the short- and mid-term outcomes of open aortic arch surgery and debranching thoracic endovascular aortic repair( TEVAR) in octogenarians.

Methods: Between 2011 and 2019, 26 patients with atherosclerotic aortic arch aneurysms underwent surgery at our institution [open aortic arch surgery( group O):10 patients, debranching TEVAR(group D):16 patients].

Results: There was no operative death in either group.

Simple Retrieval Technique of the Elephant Trunk by Partial Aortic Clamping.

The frozen elephant trunk technique for various thoracic aortic diseases is widely accepted to facilitate future downstream aortic surgery. However, in some cases, the descending aorta is unsuitable for cross-clamping due to progressive aneurysmal changes or dense adhesions to surrounding structures, and frozen elephant trunk retrieval becomes challenging. This paper presents a case of successful frozen elephant trunk retrieval by partial clamping of the descending aortic aneurysm without dissection of peri-aneurysmal adhesions, and subsequent encircling.

Aortic remodelling effect of the frozen elephant trunk technique on Stanford type A acute aortic dissection.

Total arch replacement using the frozen elephant trunk procedure is performed for true lumen expansion of the descending aorta in patients with type A acute aortic dissection. However, the remodelling effect of the frozen elephant trunk on the dissected descending aorta is unclear. We aimed to evaluate the effect of the frozen elephant trunk on postoperative descending aortic remodelling after surgery.

Aortobifemoral Bypass Grafting with Reversed L-Shaped Technique for Endograft Infection.

Endograft infection after abdominal endovascular aortic repair is a rare but catastrophic complication associated with high perioperative mortality and postoperative recurrent infection. The optimal surgical treatment is still controversial, particularly regarding in situ or extra-anatomical revascularization. Herein, we describe a successful surgically treated case of a patient with an endograft infection complicated with abscess formation in the retroperitoneal space around the right common iliac artery.

Right-sided double valve replacement in an adult patient who underwent surgery for pulmonary stenosis in childhood: a case report.

Background: Pulmonary regurgitation and the subsequent functional tricuspid regurgitation are frequently observed in adult patients who previously underwent pulmonary valvular operations. Pulmonary valve replacement, in combination with tricuspid annuloplasty, is frequently performed in adult patients. However, postoperative worsening or recurrence of tricuspid regurgitation is a major concern after pulmonary valve replacement with tricuspid annuloplasty.

Ruptured aneurysm of coronary arteriovenous fistula without aneurysmal coronary artery.

Background: Approximately 25% of coronary arteriovenous fistulas present aneurysmal dilatation; however, spontaneous rupture of the aneurysm is rare. Most coronary arteries branching the feeding arteries demonstrate aneurysmal formation, possibly because of shunt flow.

Case Report: A 48-year-old woman was referred to our institution for surgical management of ruptured aneurysm of coronary arteriovenous fistula.

Popliteal Artery Pseudoaneurysm Associated with Osteochondroma.

Osteochondroma is the most common benign bone tumor, which can sometimes cause vascular complications. Here we report two rare cases (a 48-year-old woman and a 28-year-old woman) presenting with pain and a pulsatile mass in the popliteal region. Computed tomography revealed pseudoaneurysm in the popliteal artery, which was closely associated with a protrusion of a femoral osteochondroma.

Novel Surgical Technique for Coronary Fistulas With Proximal Origin.

Postoperative residual shunting is a significant concern in patients with coronary arteriovenous fistulas, especially in fistulas originating from the proximal left coronary artery, because of the limited surgical field. We report a case of fistulas originating from the proximal coronary artery in a 63-year-old woman in whom the ascending aorta and pulmonary artery were transected to obtain good surgical exposure. After complete transection of both great arteries, fistulas arising from the left main trunk were ligated externally, and their intracardiac openings were closed internally.

Life-threatening subdural hematoma after aortic valve replacement in a patient with Heyde syndrome: a case report.

Background: Heyde syndrome is known as a triad of calcific aortic stenosis, anemia due to gastrointestinal bleeding from angiodysplasia, and acquired type 2A von Willebrand disease. This acquired hemorrhagic disorder is characterized by the loss of the large von Willebrand factor multimers due to the shear stress across the diseased aortic valve. The most frequently observed type of bleeding in these patients is mucosal or skin bleeding, such as epistaxis, followed by gastrointestinal bleeding.

[Bilateral pulmonary artery banding for complex congenital heart disease in a patient with trisomy 13; report of a case].

We described a case of a neonate of 13 trisomy with hypoplastic aortic arch and multiple ventricular septal defect (VSD). The patient presented symptoms of congestive heart failure due to pulmonary high flow. Because of ductal patency without prostaglandin infusion, bilateral pulmonary artery banding was performed for regulation of pulmonary high flow.

[Successful surgical treatment for aortic valve regurgitation and thoracoabdominal aortic aneurysm in a patient with homozygous familial hypercholesterolemia; report of a case].

A 46-year-old woman with homozygous familial hypercholesterolemia was referred due to aortic regurgitation. The patient was introduced selective low density lipoprotein cholesterol(LDL)apheresis 20 years ago. Echocardiogram revealed severe aortic regurgitation, and computed tomography revealed thoracoabdominal aortic aneurysm.

[Intraoperative cerebral malperfusion complicated with axillary artery cannulation].

To minimize the risk of malperfusion, axillary arterial cannulation which avoids retrograde flow, has been widely used in patients undergoing operations for various types of aortic pathologies. Despite several advantages of this technique, cerebral malperfusion is getting known and might be due to newly developed arterial damage or dissection. Eighty-four patients underwent cannulation of the axillary artery in recent 5 years.

[Re-do operation for coronary stenosis after Cabrol procedure; report of a case].

The Cabrol technique has been used to reimplant coronary arteries at the time of aortic root replacement. We describe a case of coronary stenosis after Cabrol procedure. A 42-year-old female with Marfan syndrome and chronic type B dissection who underwent aortic root replacement with Cabrol procedure complained of chest pain.

[Our technical modification of aortic valve sparing operation focused on standardization and reproducibility].

Background: The aortic valve-sparing operation has been accepted as an ideal procedure for the treatment of aortic root aneurysm, especially in young patients. However, this operation is thought to be technically difficult due to lack of conceptual understanding of the procedure for many surgeons. In order to overcome the surgical problem, we have developed a simple valve-sparing aortic root replacement focused on standardization and reproducibility.
