Project description:BackgroundCoronary subclavian steal syndrome (CSSS) is an often easily overlooked cause of angina that may occur after a coronary artery bypass graft (CABG) procedure. The onset of CSSS several years after coronary revascularization has been described in case reports, and in the few retrospective reviews that compare the endovascular approach with surgical treatment. Subclavian stenosis can naturally coincide with coronary artery disease and may already be present during the initial CABG.Case summaryA 59-year-old male with a history of three-vessel disease who had a left internal mammary artery (LIMA) bypass graft, exhibited a gradual worsening of angina that coincided with numbness and impaired function of the left fingers, hand, and arm. Myocardial perfusion imaging showed reversible ischaemia, and coronary angiography suggested a thrombotic lesion proximal to the LIMA ostium. Calcified and partially thrombosed proximal left subclavian artery (LSA) aneurysm was visualized using computed tomography imaging, whereas Doppler ultrasound revealed a partially reversed vertebral flow. The lowest risk treatment was a bypass between the left common carotid artery and the LSA. The procedure was immediately successful, with cessation of symptoms and a favourable medium-term outcome.DiscussionAs no guidelines exist for such cases, the importance of multidisciplinary co-operation in diagnostics and devising a treatment plan is underlined. Moreover, screening for subclavian artery stenosis in CABG candidates should be warranted as part of the initial preoperative assessment.

Project description:Vascular rings are a rare congenital anomaly of the aortic arch, in which a ring-shaped structure forms, surrounding the trachea and/or esophagus, potentially causing compression. We describe the case of a 14-month-old female patient with failure to thrive secondary to dysphagia, and a vascular ring formed by a right aortic arch, an aberrant left subclavian artery, and a left ligamentum arteriosum. Surgical repair involved ligamentum arteriosum division, Kommerell's diverticulum obliteration, and left subclavian artery re-implantation into the left carotid artery. Endoscopy and EndoFLIPTM evaluated the intraoperative improvement in esophageal narrowing and impedance, respectively. The postoperative period was uneventful, and follow-up visits demonstrated dysphagia resolution and a patent re-implanted left subclavian artery.

Project description:Endovascular repair for brachiocephalic artery aneurysms (BAAs) and subclavian artery aneurysms (SAAs) is often unclear. We treated 2 such cases percutaneously with covered stents. It may be an alternative to surgical repair for patients with isolated BAA or SAA. (Level of Difficulty: Advanced.).

Project description:A 32-year-old female presented with dysphagia. Radiographic studies revealed external compression of esophagus by a vascular ring. The anatomy was a right-sided aortic arch with aberrant retroesophageal left subclavian artery, emanating from a large Kommerell diverticulum (KD). Traditional repair with ligamentum division and adhesiolysis leaves a large KD still adjacent to the esophagus with the potential for persistent or recurrent symptoms. The objective of this study was the modification of operative technique to minimize the potential for persistent or recurrent symptoms. The operative repair included resection of KD with transposition of the left subclavian artery into the left carotid artery, in addition to the division of the ligamentum arteriosum and mobilization of the esophagus. The patient's dysphagia resolved and postoperative barium studies showed no residual compression. There were no significant perioperative complications. Resection of KD is a potential adjunct to traditional repair of vascular rings and might offer better long-term palliation by minimizing residual vascular compression of the esophagus.

Project description:PurposeWhether to proceed left subclavian artery (LSA) revascularization in patients with LSA coverage due to insufficient proximal landing zone (PLZ) during thoracic endovascular aortic repair (TEVAR) remains controversial.MethodsA total of 903 patients who received TEVAR were retrospectively analyzed. LSA could be covered if the PLZ was less than 15 mm accompanied with 1) a dominant or balanced right vertebral artery, 2) a complete circle of Willis, and 3) a left vertebral artery with a diameter ≥3 mm and without severe stenosis.ResultsLSA selective coverage was necessary for 35.0% (316/903) of the patients to extend the PLZ. Patients presented with weakness, pain, cooling and discoloration of the left upper extremity (LUE), and pulselessness of the left brachial artery were more in the LSA-covered group. The ischemia of LUE occurred more often in patients with LSA covered completely than in those with LSA covered partially. Functional arm status showed no significant difference in the arm, shoulder, and hand questionnaire scores at 12 months postoperative between the LSA-covered group and LSA-uncovered group, or between the LSA-covered completely group and LSA-covered partially group.ConclusionIt was safe to cover the LSA origin without revascularization if the PLZ was less than 15 mm accompanied with careful evaluation (description in method).

Project description:The frozen elephant trunk (FET) technique for total aortic arch replacement extends repair into the proximal portion of the descending thoracic aorta. Several techniques and modifications of total arch replacement have been described in the literature, and many of these iterations are related to facilitating the distal anastomosis while preserving flow to the left subclavian artery (LSCA), as well as maintaining posterior circulation of the brain via the vertebral artery, by reducing the circulatory arrest time during reconstruction. Because of the LSCA's posterior and deep anatomic location in the chest, particularly in obese patients, this revascularization is often challenging; additional concerns regarding LSCA revascularization include patients with large aortic arch aneurysms, those with dissected or calcified arteries, and reoperation. A careful plan for reconstruction is necessary. Whether revascularization is performed preoperative, intraoperative, or postoperatively, every effort should be made to include the left subclavian artery as part of the operational approach. Revascularization techniques include reimplantation as part of the island patch or direct anastomosis, stenting, bypass, transposition or a hybrid approach. The importance of maintaining circulation of the LSCA cannot be overstated. Preserving flow to the spinal cord via collaterals minimizes the risk of cord injury during FET procedure. In patients with a patent left internal mammary artery bypass, left arm arteriovenous fistula for hemodialysis, dominant circulation, or direct aortic origin of the left vertebral artery, revascularization is necessary as well. In the case of initial sacrifice, arm claudication or steal syndrome usually dictates delayed extra-anatomic revascularization in the postoperative period.

Project description:ObjectiveThe purpose of this systematic review and meta-analysis was to incorporate data from the latest clinical studies and compare the safety and efficacy of surgical left subclavian artery (LSA) revascularization and endovascular LSA revascularization during thoracic endovascular aortic repair (TEVAR).MethodsThis study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered with the PROSPERO database on 16 April 2023 (CRD42023414579). The Embase, MEDLINE (PubMed), and the Cochrane Library databases were searched from January 2000 to May 2023.ResultsA total of 14 retrospective cohort studies with a total of 1,695 patients, were included for review. The peri-operative stroke rates of the surgical and endovascular LSA revascularization groups were 3.8% and 2.6%, respectively (P = 0.97). The peri-operative technical success rates for the surgical and endovascular LSA revascularization groups were 95.6% and 93.0%, respectively (P = 0.24). The peri-operative spinal cord ischemia rates were 1.6% (n = 18) and 1.9% (n = 7) in the surgical and endovascular LSA revascularization groups, respectively (P = 0.90). The peri-operative type Ⅰ endoleak rates for the surgical and endovascular LSA revascularization groups were 6.6% and 23.2%, respectively (P = 0.25). The subgroup analysis showed that the incidence of peri-operative type I endoleak in the parallel stent group was significantly higher than that in the surgical LSA revascularization group (P < 0.0001). The peri-operative left upper limb ischemia rates for the surgical and endovascular LSA revascularization groups were 1.2% and 0.6%, respectively (P = 0.96). The peri-operative mortality rates of the surgical and endovascular LSA revascularization groups were 2.0% and 2.0%, respectively (P = 0.88).ConclusionThere was no significant difference in the terms of short-term outcomes when comparing the two revascularization techniques. The quality of evidence assessed by GRADE scale was low to very-low. Surgical and endovascular LSA revascularization during TEVAR were both safe and effective. Compared with surgical LSA revascularization techniques, parallel stent revascularization of LSA significantly increased the rate of type I endoleak.

Project description:BackgroundIgG4-related disease (IgG4-RD) is a chronic fibroinflammatory condition with multiple-organ involvement. Rupture of coronary artery aneurysms (CAAs) in IgG4-RD is rare.Case summaryA 65-year-old man with IgG4-RD has suffered from recurrent episodes of arterial aneurysms since 2003. He presented with chest pain and hypotension caused by localized cardiac tamponade at right ventricle free wall due to the rupture of coronary artery aneurysm (CAA) of left anterior descending artery (LAD). An urgent LAD aneurysm repaired with bovine pericardium and obliterated aneurysmal sac with cryo-acrylate glue was done together with coronary artery bypass grafting (CABG) using saphenous vein graft (SVG) to LAD and SVG to posterior descending artery. Three-month after surgery, the follow-up coronary computed tomography angiography (CCTA) revealed a growing in size of LAD and the second obtuse marginal (OM) branch aneurysm. Heart team discussion agreed to schedule the patient for double coil embolization to LAD and second OM aneurysm under intravascular ultrasound guidance. Both aneurysms were successfully obliterated with vascular coils. Two-week follow-up coronary angiogram showed complete occlusion of LAD aneurysm and near occlusion of the second OM branch aneurysm.DiscussionCoronary artery aneurysm rupture is a life-threatening condition that required prompt detection and treatments. In IgG4-RD patients, acute cardiac tamponade suggesting the rupture of CAA. Coil embolization is an alternative treatment in patients who suffered from recurrent CAA after surgical repair. Serial CCTA is important for early detection of aneurysm in IgG4-RD patients who had vascular involvement.

Project description:Subclavian artery pseudoaneurysms are rare and associated with high morbidity and mortality. Alternative approaches to open surgical repair can include endovascular repair or ultrasound-guided thrombin injection. Here, we describe a safe and novel technique of closure of a subclavian artery pseudoaneurysm with Angio-Seal that was unresponsive to thrombin injection and in a difficult location for open repair.

Project description:ObjectiveTo describe the feasibility and outcomes of endovascular repair of distal aortic arch aneurysms using a patient-specific stent graft with a pre-loaded single retrograde left subclavian artery (LSA) branch stent graft.MethodsWe reviewed the clinical data and outcomes of consecutive patients enrolled in an ongoing prospective, non-randomized physician-sponsored investigational device exemption study to evaluate the outcomes of endovascular aortic arch repair using patient-specific arch branch stent grafts (William Cook Europe, Bjaeverskov, Denmark) between 2019 and 2022. All patients received a design with triple-wide scallop and a single retrograde LSA branch with a pre-loaded catheter.ResultsThere were five male patients with median age of 77 years old (72-80) treated using the single LSA branch stent graft. Technical success was achieved in all patients. Median operating time, fluoroscopy time, and total radiation dose area product were 103 (78-134) minutes, 26 (19-39) minutes, and 123 (71-270) mGy.cm2, respectively. There were no 30-day or in-hospital mortality, neurological or other major adverse events (MAEs). During median follow-up of 21 (20-27) months, all patients were alive with patent LSA branches, except for one who died of COVID-19 complications. There was no branch instability or secondary interventions.ConclusionThis early feasibility study demonstrates successful endovascular repair of distal aortic arch aneurysms using a patient-specific stent graft with single retrograde LSA branch without technical failures, mortality or neurological events. Larger clinical experience and longer follow-up are needed to determined effectiveness of this approach in patients who need endovascular repair with proximal extension into Zone 2.
