Nationwide Outcome Analysis of Primary Carotid Endarterectomy in Symptomatic Patients Depending on Closure Technique and Patch Type
Eur J Vasc Endovasc Surg. 2023 Jan 2:S1078-5884(22)00875-9. doi: 10.1016/j.ejvs.2022.12.033. Online ahead of print.
ABSTRACT
OBJECTIVE: Current European guidelines recommend both eversion carotid endarterectomy (CEA) and conventional CEA with routine patch closure, rather than routine primary closure. Polyester and polytetrafluoroethylene (PTFE) have been used as patch material for a long time. More recently, bovine pericardium has been used; however, there are few studies comparing long term results between bovine pericardium and other patch types. The aim of this study was to investigate the short and long term results after CEA depending on surgical technique and patch material.
METHODS: A registry based study on all primary CEAs (n = 9 205) performed for symptomatic carotid artery stenosis in Sweden from July 2008 to December 2019, cross linked with data from the Swedish stroke registry, Riksstroke, and chart review for evaluation of any events occurring during follow up. The primary endpoint was ipsilateral stroke < 30 days. Secondary endpoints included re-operations due to neck haematoma and < 30 day ipsilateral stroke, > 30 day ipsilateral stroke, all stroke > 30 days, and all cause mortality.
RESULTS: 2 495 patients underwent eversion CEA and 6 710 conventional CEA for symptomatic carotid stenosis. The most commonly used patch material was Dacron (n = 3 921), followed by PTFE (n = 588) and bovine pericardium (n = 413). A total of 1 788 patients underwent conventional CEA with primary closure. Two hundred and seventy-three patients (3.0%) had a stroke < 30 days. Primary closure was associated with an increased risk of ipsilateral stroke and stroke or death <30 days: odds ratio 1.7 (95% confidence interval [CI] 1.2 – 2.4, p = .002); and 1.5 (95% CI 1.2 – 2.0), respectively. During follow up (median 4.2 years), 592 patients had any form of stroke and 1 492 died. There was no significant difference in long term risk of ipsilateral stroke, all stroke, or death depending on surgical technique or patch material.
CONCLUSION: There was an increased risk of ipsilateral stroke < 30 days in patients operated on with primary closure compared with eversion CEA and patch angioplasty. There was no difference between primary closure, different patch types, or eversion after the peri-operative phase.

Left atrial dissection after a supra-annular mitral valve replacement for endocarditis
Left atrial dissection is a rare and a potentially fatal complication of cardiac surgery. Multi-modal imagery is helpful for the diagnosis and to guide the treatment.
Bovine pericardial patch repair for abdominal aortic pseudoaneurysm to preserve lumbar arteries
Interact Cardiovasc Thorac Surg. 2022 Nov 8;35(6):ivac261. doi: 10.1093/icvts/ivac261.
ABSTRACT
We describe a case of aortic repair using bovine pericardium for a pseudoaneurysm of a dissecting abdominal aorta. A 71-year-old man had undergone several aortic replacement surgeries for type B aortic dissection. He developed paraparesis after thoraco-abdominal aortic surgery and recovered. After 3 years, the scheduled computed tomography scan showed a pseudoaneurysm of the dissecting abdominal aorta. Because he was at high risk of spinal cord ischaemia, aortic repair using bovine pericardium was performed, and all lumbar arteries were preserved. During the 12-month follow-up, he was asymptomatic, and computed tomography scans showed no dilation of the aorta.

Successful Staged Repair of Double Rupture after Acute Myocardial Infarction:Report of a Case
Kyobu Geka. 2023 Mar;76(3):212-215.
ABSTRACT
Double rupture is a very rare, and life-threatening complication after acute myocardial infection (AMI), which defined as the coexistence of any two of the three types of rupture include left ventricular free wall repture (LVFWR), ventricular septal perforation (VSP) and papillary muscule repture (PMR). We report here a case of successful staged repair of double rupture combined LVFWR and VSP. A 77-year-old woman with diagnosis of AMI in the anteroseptal area fell into cardiogenic shock suddenly just before starting coronary angiography. Echocardiography showed left ventricular free wall rupture, then an emergent operation was performed under intraaortic balloon pumping (IABP) and percutaneous cardiopulmonary support (PCPS) assistance using bovine pericardial patch and felt sandwich technique. Intraoperative transesophageal echocardiography revealed ventricular septal perforation on the apical anterior wall. Her hemodynamic condition was stable, therefore we selected a staged VSP repair to avoid surgery on freshly infarcted myocardium. Twenty-eight days after the initial operation, VSP repair was performed using the extended sandwich patch technique via right ventricle incision. Postoperative echocardiography revealed no residual shunt.
