Application of Abdominal Aortic Balloon Occlusion Combined with Tourniquet in Pregnant Women with Severe Placenta Accreta Spectrum

Objective Abdominal aortic balloon occlusion(AABO)is a vascular intervention method that has been widely used in the treatment of severe placenta accreta spectrum(PAS).The aim of this study was to investigate the benefits,potential risks,and characteristics of AABO combined with tourniquet binding of the lower uterine segment(LUS)in treatment of pregnant women with PAS.Methods In this study,64 pregnant women with PAS scores greater than 5 were enrolled as research subjects and divided into two groups.Group A(n=34)underwent normal operative procedures including tourniquet binding of the LUS.Group B(n=30)underwent AABO combined with tourniquet binding of the LUS.General clinical characteristics,ultrasonography PAS score,intraoperative blood loss(IBL),blood loss within 24 h after surgery(24-h BL),postoperative complications,and neonatal data of the two groups were retrospectively reviewed.The influencing factors of IBL for the two groups were analyzed.Results The amounts of IBL,24-h BL,total input red blood cell,and the incidence of disseminated intravascular coagulation were significantly lower in group B than in group A(P<0.05),and this difference was even more significant in the subgroup of placenta percreta(PAS scores≥10).Further multivariate linear analysis showed that the combined therapy of AABO and tourniquet could independently predict lower IBL than normal operative procedures did(P=0.001).Conclusion AABO combined with tourniquet binding of the LUS could improve the outcomes of pregnant women with severe PAS and reduce serious peripartum complications of AABO.

Abdominal Aortic Aneurysm Repair in a Patient with Superior Mesenteric Artery Occlusion with Transient Intraoperative Infusion of the Inferior Mesenteric Artery: A Surgical Case Report

Abdominal aortic aneurysms (AAA) with mesenteric artery stenosis or obstructive lesions are occasionally recognized. While performing the graft replacement operation in such cases, if the collateral circulation supplying the gastrointestinal tract is well developed, it is necessary that this collateral circulation should be well perfused during aortic cross-clamping. A 72-year-old woman was admitted because of expansion of AAA. Computed tomography (CT) scan examination revealed occlusion at the origin of the superior mesenteric artery (SMA) and the development of a collateral circulatory pathway via the inferior mesenteric artery (IMA). During this operation, a vein cannula was placed in the IMA, through which blood was supplied with an extension tube for the protection of the intra-abdominal organs. The IMA was reimplanted after the graft replacement. Previous reports indicate that intestinal ischemia may be successfully prevented by supplying blood to the collateral circulation using various techniques. We report the surgical approach for treatment of AAA using a simple and convenient method to maintain intra-operative blood supply to vital organs.

Coarctation of aorta with complete aortic occlusion

Survival to advanced age is exceptional in patients with unrepaired aortic coarctation. We report the case of an 81-year-old man with aortic coarctation and total occlusion who was otherwise asymptomatic. Coarctation was suspected when a femoral-radial pulse delay was noted during his routine physical examination. A 70-mmHg systolic blood.

Acute Aortic Occlusion in a Critically Ill Adult Presenting to the Emergency Department

Acute Aortic Occlusion (AAO) is a rare, life-threatening event so far described mainly in small-scale series. The most common causes of AAO are large saddle emboli to the aortic bifurcation, in-situ thrombosis of an atherosclerotic aorta, and occlusion of previous surgical reconstruction. We present the case of a 52-year-old female with rheumatic heart disease, ischemic cardiomyopathy with restricted left ventricular function, atrial fibrillation, and previous cardio-embolic stroke, who was brought to the Emergency Department (ED) with sudden-onset dyspnea and lower backache radiating to both the legs. On arrival at the ED, the patient was electively intubated and mechanically ventilated in view of hypoxia and altered mental status, attributed to respiratory failure secondary to acute cardiogenic pulmonary oedema. The secondary survey revealed absence of bilateral femoral and popliteal artery pulsations. A computed tomography (CT) aortogram showed a complete lumen occlusion thrombus in the infra-renal region of the abdominal aorta at the level of L3-L4 lumbar vertebrae. An emergency embolectomy was performed successfully, following which the patient was started on heparin infusion and managed in the Intensive Care Unit (ICU). In the ICU, she suffered a torsade-cardiac arrest, with return of spontaneous circulation (ROSC) following rapid defibrillation. She was extubated on Day 3. Three weeks later, she was discharged from the hospital. At the time of discharge, she had developed ischemic lumbosacral radiculoplexus neuropathy, for which neuro-rehabilitation was advised. In our case report, we would like to highlight the following key points: 1) The importance of a detailed secondary survey in the Emergency Department (ED). 2) An inter-disciplinary approach to a complex syndrome that ensures the highest probability of a good outcome. .

Clinical study of transcatheter occlusion in treating ventricular septal defect combined with right coronary cusp bulge

Background: Perimembranous ventricular septal defect combined with right coronary cusp bulge generally should be treated with surgical thoracotomy, owing to the potential aortic regurgitation. However, the minimally invasive method of transcatheter closure has always attracted the attention of cardiologists and patients. The present study aimed to apply transcatheter occlusion in treating ventricular septal defect with right coronary cusp bulge and further evaluate the clinical effect through follow-up. Materials and methods: A total of 40 children diagnosed as having a ventricular septal defect with right coronary cusp bulge, examined using transthoracic echocardiography and cardiovascular angiography, were enrolled in this study. The ventricular septal defects were closed by placing occluders through transcatheter occlusion treatment. During the operation process, the children underwent angiography and transthoracic echocardiography examinations to check the position of the occlude and the extent of aortic regurgitation. The influence of occlusion on the conduction system was evaluated using a surface electrocardiogram. The children were followed up after their procedures. Results: All 40 patients were immediately and successfully occluded. Three patients with filament residual shunts were observed during the operations. No major surgical complications occurred during the perioperative period. During the follow-up period, the positions of all the occluders were good, the residual shunts in the three patients disappeared, and no new or aggravated aortic regurgitation occurred. Electrocardiogram did not reveal any atrioventricular blocks. Only one patient suffered from an incomplete right bundle branch block. Conclusions: Children diagnosed with ventricular septal defect combined with right coronary cusp bulge could be considered for transcatheter occlusion. With appropriate indications and methods, the effect may be favorable.

Aortic Dissection Complicated with Fatal Cerebral Infarction: Case Report and Review of Literatures

Acute aortic dissection is a life-threatening condition requiring immediate assessment and therapy. Rarely, aortic dis-section involves carotid arteries and manifest cerebral infarction. Here, we report a case of aortic dissection complicated with fatal cerebral infarction. A 83-year-old man, who suddenly suffered consciousness disturbance and right hemiparesis, was transferred to our hospital for the treatment of stroke. Magnetic resonance image revealed massive cerebral infarction in the left cerebral hemisphere as well as occlusion of the left internal carotid artery. Duplex ultrasonography demonstrated arterial dissection in the bilateral carotid arteries and the blood flow was compromised especially in the left side. Aortic dissection was confirmed by the contrast enhanced computed tomography. He was treated conservatively and died of cerebral hernia three days after the onset. In conclusion, aortic dissection may involve carotid artery and results in cerebral infarction. Ultrasound screening can aid timely diagnosis of aortic dissection and further management.

Recovery from Out-of-Hospital Cardiopulmonary Arrest Due to Type A Acute Aortic Dissection: A Case Report

Case: A 55-year-old man without past medical histories suffering from back pain for two weeks was successfully resuscitated from an 8-min cardiopulmonary arrest (CPA) and was brought to our hospital by ambulance. Computed tomography demonstrated type A acute aortic dissection (AAAD) with brachiocephalic artery occlusion. After admission, Glasgow Coma Scale score improved to E1VTM4, and voluntary movement was noted only in the right limbs. Outcome: The patient underwent emergency grafting of the ascending aorta and innominate artery under deep hypothermic circulatory arrest. After surgery, the patient recovered with mild disorientation and left hemiplegia. Magnetic resonance imaging of the head revealed no large infarction but revealed multiple acute ischemic changes. One year later, the patient demonstrated independent walk and successfully returned to work life. Conclusions: Immediate resuscitation and surgery resulted in good recovery from CPA after AAAD.

Elevated plasma level of matrix metalloproteinases-9 and its significance in patients with abdominal aortic aneurysms

Objective: To investigate the changes of the plasma level of MMP-9 (Matrix Metalloproteinase-9, MMP-9) in the patients with abdominal aortic aneurysms (AAAs) before and after the treatment, and evaluate the significance of MMP-9 in the pathogenesis of AAAs. Methods: Blood samples of 35 patients with AAAs and 10 patients with the arterial occlusive diseases (AODs) , which enrolled into the Vascular Surgery Center of Colonge University Hospital from February to August of 2002, were collected before and one month after surgical repair or less-invasive endovascular exclusion. The plasma concentrations of MMP-9 of all the collected samples were measured by means of enzyme-linked immunosorbent assay(ELISA), and compared between the two groups patients at different time point. Results: The mean plasma concentration of MMP-9 of AAAs was significantly higher than that of AODs prior to treatment [(90.3±9.1) ng/ml vs (23.6±7.3) ng/ml, P<0.05], and no apparent difference was showed in the patients with AODs [(23.6±7.3) ng/ml vs (25.3±5.8) ng/ml, P>0.05)] before and after the surgical bypass operation. However, in the patients with AAAs the plasma concentration of MMP-9 was apparently decreased one month after the surgical repair or endovascular exclusion compared with before [(28.6±8.4) ng/ml vs (90.3±9.1) ng/ml, P<0.05)]. No meaningful difference of the mean plasma MMP-9 concentration was seen between two groups after the both being successfully treated [(28.6±8.4) ng/ml vs (25.3±5.8) ng/ml, P>0.05]. Conclusion: Apparent elevation of plasma concentration of MMP-9 in the AAAs and its dramatic decrease after being treated implicated that MMP-9 might play an important role in the formation and development of AAAs. Meanwhile, to investigate the changes of MMP-9 level of AAAs could provide an practical way to facilitate the earlier diagnosis and long term surveillance for AAAs. More importantly, pharmacologic prevention and treatment of AAAs, in which the MMP-9 serves as effective target, might be possible in the future.

Right coronary occlusion following transcatheter aortic valve implantation： two case reports

This paper discusses two male patients with severe aortic stenosis, whose right coronary arteries （RCA） were completely occluded during transcatheter aortic valve implantation （TAVI）, leading to fatal hemodynamic disorder. Occlusions of RCA complicated by TAVI are rare. In addition, emergency cardiopulmonary bypass （CPB） played a critical role in rescuing our second patient. Both patients were admitted for ＂severe aortic stenosis,＂ and TAVIs were performed. The first patient＇s blood pressure immediately dropped to 70/40 mmHg after the balloon expansion and did not increase much after the administration of aramine or fluid therapy. He did not receive emergency surgery and died after 1.5 h of resuscitation. The second patient＇s blood pressure fluctuated greatly for several minutes after the valve implantation, ranging from 170/100 mmHg to 60/40 mmHg. Angiography revealed a total occlusion of RCA. Thoracic surgery with CPB was performed, and the patient survived.

Totally Occluded Coarctation of the Aorta in a Young Adult

We report the case of a 20-year-old female patient presenting with a totally occluded coarctation of the aorta. The patient was admitted for the evaluation of resistant grade III high blood pressure. The physical examination revealed a blood pressure gradient between the upper and lower limbs, absent femoral pulses, a diffuse continuous murmur over the chest, and hyperpulsatility of the carotid arteries and sternal notch. A transthoracic echocardiography outlined a narrowing in the caliber of the isthmic aorta without acceleration of flow or gradient. Thoracic CT angiography revealed a complete aortic coarctation with interruption of continuity between segment 3 and the descending aorta.

Intra-abdominal aortic balloon occlusion in the management of placenta percreta

Background:Massive bleeding is the main concern for the management of placenta percreta(PP).Intra-abdominal aortic balloon occlusion(IABO)is one method for pelvic devascularization,but the efficacy of IABO is uncertain.This study aims to investigate the outcomes of IABO in PP patients.Methods:We retrospectively reviewed the clinical data of PP cases from six tertiary centers in China between January 2011 and December 2015.PP cases with/without the use of IABO were analyzed.Propensity score matching analysis was performed to reduce the effect of selection bias.Postpartum hemorrhage(PPH)and the rate of hysterectomy,as well as neonatal outcomes,were analyzed.Results:One hundred and thirty-two matched pairs of patients were included in the final analysis.Compared with the control group,maternal outcomes,including PPH(68.9%vs.87.9%,χ^(2)=13.984,P<0.001),hysterectomy(8.3%vs.65.2%,χ^(2)=91.672,P<0.001),and repeated surgery(1.5%vs.12.1%,χ^(2)=11.686,P=0.001)were significantly reduced in the IABO group.For neonatal outcomes,Apgar scores at 1 minute(8.67±1.79vs.8.53±1.68,t=-0.638,P=0.947)and 5 minutes(9.43±1.55vs.9.53±1.26,t=0.566,P=0.293)were not significantly different between the two groups.Conclusions:IABO can significantly reduce blood loss,hysterectomies,and repeated surgeries.This procedure has not shown harmful effects on neonatal outcomes.
