Injection of n-Butyl-2-Cyanoacrylate into the Abdominal Aortic Aneurysm Sac during Endovascular Aortic Repair to Prevent Type II Endoleaks Caused by Lumbar Arteries.

Purpose: To evaluate midterm results of whether the strategy to occlude target lumbar arteries using n-butyl-2-cyanoacrylate (nBCA) injection during endovascular aneurysm repair (EVAR) reduced the incidence of Type II endoleak (T2EL) after EVAR.

Materials And Methods: Between 2013 and 2020, 187 patients underwent EVAR; 106 in the treatment group received nBCA injection during EVAR, whereas 81 in the historical control group did not. The incidence of T2EL at 7 days, need for reintervention, and post-EVAR aneurysmal shrinkage were compared between the groups.

Initial two-day blood pressure management after endovascular aneurysm repair improves midterm outcomes by reducing the incidence of early type II endoleak.

Objective: The aim of this study was to evaluate midterm outcomes of our novel strategy of postoperative initial 2-day blood pressure management (BPM) after endovascular aneurysm repair (EVAR) for the prevention of subsequent type II endoleak (T2EL) in a single-center series.

Methods: Between 2008 and 2014, 137 patients who underwent EVAR for abdominal aortic aneurysm (AAA) were reviewed. Starting from 2013, the mean blood pressure was maintained between 75 and 90 mmHg for the initial 24 hours after EVAR followed by systolic pressure controlled below 120 mmHg during the next 24 hours in the treatment group (n = 76).

Thoracic Endovascular Aortic Repair on Zone 2 Landing for Uncomplicated Type B Aortic Dissection with Measurement of Intra-False Lumen Pressure.

Background: This study aimed to evaluate the midterm results of zone 2 thoracic endovascular aortic repair (TEVAR) for uncomplicated type B aortic dissection (TBAD) by measuring the intra-false lumen pressure (IFLP) during TEVAR.

Methods: Fifteen patients (9 men; mean age, 57 years) who underwent zone 2 TEVAR for uncomplicated TBAD were reviewed. Delta systolic pressure (defined as the difference between systemic pressure and IFLP) was measured before and after primary entry closure, and aortic remodeling and thrombo-occlusion of the false lumen (FL) were evaluated 12 months after TEVAR at 5 different levels of the aorta.

Scattered Media Elastic Fibers from the Aortic Root to the Ascending Aorta in a 30-Year-Old Marfan Syndrome Patient.

We present a case report of a 30-year-old Marfan syndrome patient who underwent a David procedure for severe aortic valve insufficiency and Valsalva aneurysm. Harvested aortic walls were examined by pathologists. Although the tunica media of the ascending aorta contained aligned elastic fibers, the aortic root media lacked aligned elastic fibers.

Early- and Mid-Term Results of Abdominal Endovascular Aneurysm Repair Using an Aortic Cuff Prior to the Main Body to Prevent Type II Endoleaks.

Purpose: Postoperatively persistent type II endoleaks (T2ELs) in abdominal endovascular aneurysm repair (EVAR) are known risk factors for long-term aneurysm enlargement. Therefore, various measures have been proposed to prevent T2ELs. Notably, the Kilt technique, which can be used in patients with dumbbell-shaped morphology, employs an aortic cuff deployed in the distal seal zone before the main body.

Physician-modified stent graft with inner branches for treating ruptured thoracoabdominal aortic aneurysm.

Thoracoabdominal aortic aneurysm (TAAA) repair remains challenging in patients with high surgical risk. We report a case of TAAA in an 84-year-old woman with type Ib endoleak after thoracic endovascular aortic repair with coeliac artery coverage due to impending ruptured TAAA. A stent graft was assembled to create 3 fenestrations and sew 3 inner grafts for the superior mesenteric artery (SMA) and bilateral renal arteries.

Descending thoracic aorta-abdominal aortic bypass and bilateral renal arterial blood circulation reconstruction are effective in atypical coarctation of the aorta with heart failure: a case report.

Background: There are a lot of reports of the renal failure and heart failure due to coarctation of the aorta. However, there are no case reports in which revascularization dramatically improved left ventricular function in patients with progressive decline in left ventricular function. Herein, we present a rare case in which the left ventricular function was dramatically improved by surgical treatment for progressive left ventricular dysfunction due to atypical coarctation of the aorta.

A case of a giant pulmonary artery aneurysm due to an atrial septal defect with left main coronary artery occlusion.

Cases of coronary artery occlusion due to the exclusion of pulmonary artery aneurysm are extremely rare, and there are few reports of surgical treatment. A 60-year-old woman with pulmonary hypertension due to an atrial septal defect and obstruction of the left main coronary trunk due to the exclusion of a giant pulmonary artery aneurysm underwent surgery. The surgery included atrial septal defect closure, tricuspid annulus plasty, pulmonary artery aneurysmorrhaphy, and coronary artery bypass grafting.

Successful Endovascular Repair of an Abdominal Aortic Aneurysm in a Patient with a Horseshoe Kidney and Accessory Renal Arteries Using an Aortic Cuff to Prevent Type II Endoleak.

A 78-year-old man presented with an abdominal aortic aneurysm (AAA) and a horseshoe kidney coexisting with accessory renal arteries. We performed surgical treatment with endovascular aneurysm repair, sacrificing the accessory renal arteries. We used an aortic cuff to prevent a type II endoleak from the inferior mesenteric and accessory renal arteries.

Antiatherosclerotic Phenotype of Perivascular Adipose Tissue Surrounding the Saphenous Vein in Coronary Artery Bypass Grafting.

Background Perivascular adipose tissue (PVAT) is associated with metabolically driven chronic inflammation called metaflammation, which contributes to vascular function and the pathogenesis of vascular disease. The saphenous vein (SV) is commonly used as an essential conduit in coronary artery bypass grafting, but the long-term patency of SV grafts is a crucial issue. The use of the novel "no-touch" technique of SV harvesting together with its surrounding tissue has been reported to result in good long‑term graft patency of SV grafts.

Estimation Model for Hypothermic Circulatory Arrest Time to Predict Risk in Total Arch Replacement.

Background: We created an estimation model for hypothermic circulatory arrest time and analyzed the risk factors for major adverse outcomes in total arch replacement.

Methods: This study involved 272 patients who underwent total arch replacement. The estimation model for hypothermic circulatory arrest time was established using multiple linear regression analysis, and the predicted hypothermic circulatory arrest time from this model was analyzed to detect risk factors.

Long-Term Clinical Outcomes of Thoracic Endovascular Aortic Repair for Arch Aneurysms with the Najuta Thoracic Stent-Graft System.

: The treatment for arch aneurysms by endovascular repair is often difficult. This study evaluated the long-term outcomes of thoracic endovascular aortic repair for aortic arch aneurysms treated with the Najuta stent-graft system. : From January 2009 to December 2019, 37 patients underwent treatment for aortic aneurysms with the Najuta stent graft system at two institutes, including our hospital.

A rare case of pseudoaneurysm at the site of untreated coarctation of the aorta in an adult patient.

Here we report a rare case of pseudoaneurysm at the site of aortic coarctation. Aortic coarctation and a saccular aortic aneurysm protruding from the site of this coarctation were detected in a 50-year-old woman. Owing to the shape of the aneurysm and high risk of rupture, an open surgical repair was performed.

Surgical Treatment of a Left Axillary Arterial Aneurysm with Marfan Syndrome by Combining Two Skin Incisions.

An axillary arterial aneurysm is a rare disorder, with few surgical cases reported to date. Here we report the case of a left axillary arterial aneurysm associated with Marfan syndrome. A 44-year-old female with Marfan syndrome presented with numbness of the left upper limb and a pulsatile mass on the left chest.

[Left Ventricular Patch Plasty for Post-infarct Ventricular True Aneurysm with Ventricular Septal Perforation;Report of a Case].

We experienced a rare case of post-infarct left ventricular aneurysm (LVA) and ventricular septal perforation (VSP). An 83-year-old woman was treated for acute cardiac insufficiency. Three weeks later after hospitalization, she had sudden cardiorespiratory failure and was diagnosed with VSP and LVA.
