Relationship Between Renal Function and Renal Artery Involvement in Acute Debakey Type I Aortic Dissection.

Background: The aim of this study was to analyse the differences in renal function among various types of renal artery involvement in acute Debakey Type I aortic dissection.

Methods: From January 2016 to January 2018, 304 consecutive patients with acute Debakey type I aortic dissection with renal artery involvement were included. According to computed tomography angiography (CTA) findings, renal artery involvement on one side can be classified into four types: type A, in which a large intimal tear is near the renal artery orifice; type B, the orifice of the renal artery originates entirely from the false lumen; type C, the orifice of the renal artery originates entirely from the true lumen; and type D, a renal artery dissection is observed.

Aortic dissection during pregnancy and postpartum in patients with Marfan syndrome: a 21-year clinical experience in 30 patients.

Objectives: Pregnancy-related aortic dissection (AoD) in Marfan syndrome is a lethal catastrophe. Due to its rarity and limited clinical experience, there is no consensus regarding the optimal management strategy. We seek to present our 21-year experience in such patients , focusing on management strategies and early and late outcomes.

Repair of Type Ia Endoleaks Involving the Distal Arch Using Left Subclavian Artery-Left Common Carotid Artery Transposition with a Stented Elephant Trunk.

Background: Type Ia endoleaks are common after thoracic endovascular aortic repair (TEVAR). However, the repair of type Ia endoleaks involving the distal arch is challenging because of the presence of the interventional endografts, potential damage to the aortic arch vessels, and the location and size of the aneurysmal body. We retrospectively reviewed our experience of the surgical treatment of type Ia endoleaks with distal arch involvement using left subclavian artery (LSCA)-left common carotid artery (LCCA) transposition with a stented elephant trunk.

Successful repair of acute type A aortic dissection during pregnancy at 16 gestational week with maternal and fetal survival: A case report and review of the literature.

Background: Aortic dissection during pregnancy is a rare but life-threatening event for mothers and fetuses. It often occurs in the third trimester of pregnancy and the postpartum period. Most patients have connective tissue diseases such as Marfan syndrome.

Frozen elephant trunk with modified arch reconstruction and left subclavian transposition for chronic type A dissection.

Background: Several methods of arch vessel reconstruction, such as (island) and branched graft techniques, have been proposed to treat aortic arch pathologies during total arch replacement (TAR). We seek to review our experience with modified en bloc technique and left subclavian (LSCA)-left carotid artery (LCCA) transposition in TAR and frozen elephant trunk (FET) procedure for chronic type A aortic dissection (CTAAD).

Methods: From September 2010 to September 2016, 35 consecutive patients with CTAAD underwent modified arch reconstruction with LSCA-LCCA transposition during TAR and FET procedure.

Frozen Elephant Trunk for Acute Type B Dissection Involving the Distal Arch in the Hybrid Repair Era.

Background: Hybrid repair of complicated acute type B aortic dissection (ATBAD) with aortic arch involvement is associated with a high rate of endoleak, stroke, and retrograde aortic dissection. Optimal management of this lesion remains uncertain. In this hybrid repair era, surgical results of ATBAD with distal aortic arch involvement using a frozen elephant trunk procedure with transposition of the left subclavian artery (LSCA) to left common carotid artery (LCCA) is reported.

The repair of a type Ia endoleak following thoracic endovascular aortic repair using a stented elephant trunk procedure.

Background: Type Ia endoleaks are not uncommon complications that occur after thoracic endovascular aortic repair (TEVAR). Because aortic arch vessels prevent extension of the landing zone, it is very difficult to manipulate a type Ia endoleak using an extension cuff or stent-graft, especially when the aortic arch is involved. Here, we retrospectively review our experience of surgical treatment of type Ia endoleak after TEVAR using a stented elephant trunk procedure.

Treatment with Corticosteroid and/or Immunosuppressive Agents before Surgery can Effectively Improve the Surgical Outcome in Patients with Takayasu's Arteritis.

Objective: To analyze the clinical outcome of corticosteroid and/or immunosuppressive treatment preoperatively in patients with Takayasu's arteritis.

Patients And Methods: Forty-six patients with Takayasu's arteritis who received cardiovascular surgery between January 2010 and December 2015 in Beijing Anzhen Hospital were enrolled in this study. Their clinical characteristics, preoperative drug therapy, surgical treatment, and pathological examination results were retrospectively analyzed for the effect of drugs on outcome of the surgery.

Stented elephant trunk procedure with left subclavian artery transposition for acute type B dissection with distal arch involvement.

Objective: Complete or partial supra-aortic debranching, after thoracic endovascular aortic repair, is appealing treatment for complicated acute type B dissection (ABAD) with aortic arch involvement (AAI) because of reduced surgical trauma. However, unsatisfactory outcomes have been reported. We retrospectively reviewed our experience of left subclavian artery (LSCA) transposition with stented elephant trunk (SET) implantation for complicated ABAD with distal AAI.
