Purpose: To compare the 3-year clinical outcomes of endoluminal bypass with those of surgical bypass for complex femoropopliteal (FP) arterial lesions.
Materials And Methods: In this retrospective multicenter study, 530 patients with symptomatic peripheral artery disease (Rutherford classification 1-3, 66.0%; 4-6, 34.
Patients with organ malperfusion from acute aortic dissection (AAD) have poor outcomes, and the surgical indications for patients with AAD complicated by extensive cerebral infarction have not been established. Here, we report a successfully treated surgical case of a patient with cerebral infarction and Stanford type A, AAD. A 77-year-old man was admitted to the hospital with a chief complaint of left paresis.

Objectives: Although reoperation has been increasingly performed in cardiovascular surgery in recent years, preventing surgical adhesions remains an unsolved complication. Therefore, this study aimed to investigate whether gelatine sealing sheets are more effective than fibrin sealing sheets in preventing surgical adhesions.
Methods: Bilateral femoral arteries of 20 beagle dogs under general anaesthesia were pricked with syringe needles, and gelatine and fibrin sealing sheets were applied on the bleeding points to make canine adhesion models.
Patent false lumens carry a high risk of aortic events including rupture. False lumen embolization is a useful method to promote thrombosis of false lumen. In the case presented here, direct penetration of the dissected membrane was employed to obtain access to the false lumen, enabling embolization.

Methods: We studied 23 patients who underwent cardiac surgery between January 2018 and December 2019.
Aim: This study aimed to evaluate the structural and functional changes of left-sided cardiac chambers by cardiac magnetic resonance imaging (CMRI) in patients with chronic mitral regurgitation after mitral valve repair (MVR).
Patients And Methods: Among 103 patients who underwent MVR, 21 showed normal left ventricular (LV) function; their pre- and postoperative left atrial (LA) and LV functions were examined by CMRI.
Results: LV end-diastolic volume, LV end-systolic volume, and LV mass significantly were reduced postoperatively (p<0.
Background/aim: Treating abdominal aortic aneurysms (AAA) of the juxtarenal artery with renal artery clamps burdens the kidneys. We investigated the outcomes of intra-operative renal artery perfusion using the cold Ringer's solution method for renal protection.
Patients And Methods: We enrolled 290 AAA patients who underwent open aortic repair.
Background: Pulmonary arterial capacitance (PAC) is a determinant of right ventricular afterload and a strong independent predictor of unfavorable outcomes in advanced heart failure (HF) with pulmonary hypertension (PH). We aimed to test the hypothesis that preoperative PAC may affect postoperative clinical outcomes in patients undergoing aortic valve replacement (AVR) for severe aortic valve stenosis (AS), even in the absence of PH.
Methods and results: We studied 116 patients who underwent AVR for severe AS between January 2005 and December 2017.
Background: The aim of this study is to compare the outcome of endovascular abdominal aortic aneurysm repair (EVAR) using the Zenith Spiral Z abdominal aortic aneurysm iliac leg (ZSLE) versus the Zenith Flex abdominal aortic aneurysm iliac leg (TFLE).
Methods: Patients undergoing EVAR using TFLE or ZSLE between October 2009 and December 2017 were retrospectively reviewed. Clinical end points were freedom from limb-related complications and change in arterial tortuosity indexes.
Purpose: Fusion angiography using reconstructed multidetector-row computed tomography (MDCT) images, and cholangiography using reconstructed images from MDCT with a cholangiographic agent include an anatomical gap due to the different periods of MDCT scanning. To conquer such gaps, we attempted to develop a cholangiography procedure that automatically reconstructs a cholangiogram from portal-phase MDCT images.
Methods: The automatically produced cholangiography procedure utilized an original software program that was developed by the Graduate School of Information Science, Nagoya University.
Although laparoscopic hepatectomy is widely accepted for primary hepatectomy, the clinical value of laparoscopic hepatectomy for repeat hepatectomy is still challenging. We herein describe our experience with laparoscopic repeat hepatectomy after right hepatopancreaticoduodenectomy. A 72-year-old woman who had undergone right hepatopancreaticoduodenectomy for perihilar cholangiocarcinoma 31 months prior was diagnosed with liver metastasis in segment 3.

Objective: To examine the feasibility of crosslinked gelatin glue as an anastomotic needle hole sealant in comparison with fibrin glue.
Methods: The in vitro burst water pressures were measured for gelatin and fibrin glue sealed needle holes of expanded polytetrafluoroethylene (ePTFE) or collagen coated woven polyester grafts.
Background: Right-sided hepatectomy is often selected for perihilar cholangiocarcinoma, due to the anatomic consideration that "the left hepatic duct is longer than that of the right hepatic duct". However, only one study briefly mentioned the length of the hepatic ducts. Our aim is to investigate whether the consideration is correct.

Objective: To examine the feasibility of gelatin sealing sheets using a canine arterial hemorrhage model.
Methods: In vivo degradation of gelatin sealing sheets was examined by implanting subcutaneously in rats.
Background: Hepatectomy for an invisible small tumor using intraoperative ultrasonography requires technical ingenuity. We used a 3D print of a liver to perform a hepatectomy on two patients with synchronous multiple liver metastases from colorectal cancer. Because of preoperative chemotherapy, one of the tumors became smaller and invisible to ultrasonography in each case.

However, less than 5% of patients survive and later develop chronic thoracic aortic aneurysm (TAA). Usually, most cases of chronic traumatic TAA have no symptoms for a long time after an accident.

Left ventricular noncompaction is a rare cardiac pathology that results from an arrest in endomyocardial development in early embryogenesis. With great advances in imaging modalities, this pathological entity has been noted not only in the pediatric population but also in adults. Herein we report the case of a 62-year-old woman who successfully underwent aortic valve replacement for aortic regurgitation complicated by left ventricular noncompaction.

A 76-year-old man with systemic lupus erythematosus was found to have an aneurysm of the right sinus of Valsalva. Aortic root replacement with a stentless bioprosthesis, using a full root technique, was successfully performed. The pathological findings of the excised aortic valve were not secondary to atherosclerosis, inflammatory or infectious disease, but seemed to be compatible with those previously reported in a case of systemic lupus erythematosus.

A 79-year-old man with no history of trauma complained of a sudden onset of headache and backache. Computed tomography showed an isolated dissecting aneurysm 4 cm in diameter associated with contained rupture at the takeoff region of the brachiocephalic artery. Surgery was performed on an emergent basis.

Methods: Thirty-nine patients scheduled to undergo shoulder surgery were randomly assigned to four groups; receiving no continuous BPB (control group, n = 10), BPB with 0.
Myocardial protection in patients requiring a second open-heart surgical procedure after coronary artery bypass grafting, especially when there is a patent left internal thoracic artery graft to the left anterior descending coronary artery, remains controversial. We present the case of a patient in whom aortic valve replacement was undertaken 18 months after coronary artery revascularization. Unusual features included beating-heart aortic valve replacement with continuous retrograde coronary sinus perfusion and avoidance of dissection of the patent grafts, including the left internal thoracic artery and a saphenous vein graft.
