Type A Acute Aortic Dissection Presenting With Arch and Abdominal Aortic Aneurysms.

Herein, we present the case of an 89-year-old female who presented with acute aortic dissection involving the arch and abdominal aneurysms. Emergent total arch replacement with a frozen elephant trunk was the first-line approach taken to save the patient's life. Although prolonged mechanical ventilation necessitated a tracheostomy, subsequent endovascular aortic repair mitigated the risk of rupture in the abdominal aortic aneurysm. While managing acute aortic syndrome with multiple aneurysms poses a challenge for surgeons, a diagnosis based on computed tomography angiography and timely intervention alleviated the critical condition.

Pulsatile thrombus evacuation from the false lumen of an occluded carotid artery in acute aortic dissection.

Herein, we present a case of aortic dissection with right carotid artery occlusion that was treated successfully with thrombus evacuation from the false lumen of the occluded carotid artery during hemiarch replacement. This procedure is performed with two maneuvers: aggressive retrieval of the thrombus from the innominate artery during circulatory arrest and thrombus evacuation from the false lumen of the right common carotid artery through a right neck incision with the heart beating. In this alternative method, thrombi can be evacuated more naturally and briskly, using pulsatile flow.

Distal Arch Aneurysm Discovered With Dysphagia.

A 64-year-old man sought medical attention from a family physician, expressing concerns about dysphagia. Recognizing the complexity of the symptoms, the family physician promptly engaged the expertise of an attending physician at a regional hospital to ensure accurate diagnosis and management. Plain computed tomography (CT) revealed a space-occupied lesion located posterior to the trachea. Although mediastinal tumor was suspected at first, contrast-enhanced CT revealed a distal arch aneurysm that compressed the esophagus. The patient underwent total arch replacement, and the postoperative course was uneventful.

Deep Femoral Artery Aneurysm Resection and Revascularization With a Saphenous Vein.

An incidental discovery was made of a right deep femoral artery aneurysm (DFAA) in a plain computed tomography (CT) scan of a 72-year-old male. Although he had been diagnosed with type B aortic dissection six years ago and was followed for 12 months in the outpatient clinic, the patient was no longer receiving regular checkups. After a thorough discussion between cardiovascular surgeons and interventional radiologists, it was decided to proceed with aneurysm resection and revascularization. The postoperative course was uneventful, and the patient was discharged home without complications.

An Escherichia coli-Induced Distal Arch Aneurysm Presenting With Hemoptysis.

Infected thoracic aneurysms are a rare and potentially life-threatening condition that present with non-specific symptoms. We describe here a case of an 83-year-old female who presented to the emergency department with the chief complaint of vomiting blood. The patient had presented to the emergency department 40 days earlier with abdominal pain, fever, and leukocytosis. She had a medical history of traumatic liver injury resulting in bile duct stenosis, necessitating percutaneous transhepatic gallbladder drainage and subsequent bile duct-jejunal anastomosis 25 years ago. Emergency contrast-enhanced computed tomography (CT) revealed an irregular distal arch aneurysm. According to the patient's present symptoms, CT findings, and medical history, infected thoracic aneurysm was suspected. Total arch replacement was performed promptly, followed by thorough antibiotic therapy. Following successful treatment, the patient's condition stabilized, and she was transferred to a rehabilitation facility for further recovery.

Worsening Isolated Superior Mesenteric Artery Dissection on the Day After Discharge.

A 59-year-old male was transported to the emergency department by ambulance with complaints of left-sided abdominal pain. Blood gas analysis revealed elevated lactate, and plain computed tomography revealed no bowel ischemic change. Contrast-enhanced computed tomography revealed isolated superior mesenteric artery dissection with mildly stenosed true lumen. The patient was treated with conservative management on admission. Staged fluid intake, oral prescriptions, and diet were commenced with attention to the symptoms. After four days of hospitalization, the patient was discharged with a stable condition. However, the patient returned to our hospital complaining of left lower back pain three hours after discharge. Contrast-enhanced computed tomography revealed an enlarged false lumen with a moderately stenosed true lumen. After a thorough discussion between vascular surgeons and interventional radiologists, conservative management was commenced on the second admission. The clinical course was uneventful, with proof of improved imaging findings.

Conservative Treatment for Isolated Superior Mesenteric Artery Dissection With Severely Narrowed True Lumen.

A 59-year-old male presented to the emergency department with distressing epigastric pain after seeking medical attention at a nearby clinic three hours prior. Upon examination, the attending physician noticed edematous changes in the proximal segment of the superior mesenteric artery, and a subsequent enhanced computed tomography (CT) scan confirmed the diagnosis of an isolated dissection of the artery. Notably, the true lumen of the vessel was significantly narrowed, raising concerns for potential vascular compromise. After extensive consultation between a vascular surgeon and a radiologist, a decision was made to adopt a conservative management approach. The patient was closely monitored with meticulous bowel rest, hydration management, and carefully curated dietary modifications. Over time, subsequent CT scans revealed progressive enlargement of the true lumen, which was highly reassuring to the medical team. As a result of the expert management and diligent care provided, the patient was eventually discharged home without any adverse events or complications. This case highlights the critical role of a multidisciplinary approach in managing complex vascular pathology and underscores the importance of thoughtful clinical decision-making and meticulous monitoring in achieving favorable outcomes.

Posterior Mitral Leaflet (PML) Perforation due to Infective Endocarditis (IE) Complicated with Cerebral Infarction.

A 64-year-old man on dialysis presented to the emergency department with a fever and chills. Transthoracic echocardiography (TTE) showed small vegetation on the posterior mitral leaflet (PML). Antibiotic therapy was initiated. Two weeks later, right hemiparesis occurred. MRI of the head showed occlusion of the left middle cerebral artery, which suggested an embolism derived from the vegetation. The patient was then referred to the department of cardiovascular surgery. Transesophageal echocardiography (TEE) revealed perforation of the PML and severe mitral regurgitation (MR). The patient underwent mitral valve repair. The postoperative course was uneventful, and the patient was discharged after six weeks of antibiotic treatment. A fresh autologous pericardium is the material of choice to repair the valve.

Posterior Mitral Leaflet Prolapse and Subsequent Mitral Valve Endocarditis Complicated With Anterior Leaflet Perforation.

A 68-year-old male presented with a two-week history of fever, and further investigations revealed mitral valve endocarditis caused by Staphylococcus epidermidis, with associated severe mitral regurgitation (MR). The patient was referred for mitral valve surgery but developed new neurological symptoms two days before the operation, which were diagnosed as symptomatic epilepsy. During surgery, kissing lesions were found on the posterior mitral leaflet (PML), which were not detected on preoperative transesophageal echocardiography (TEE). Mitral valve repair was completed using autologous pericardium. The current case highlights the importance of careful examination of leaflets during surgery and not relying solely on preoperative imaging to detect all lesions. It is essential to promptly diagnose and treat infective endocarditis to prevent further complications and ensure successful outcomes.

Management of Coronary Artery Bypass Grafting Using an Arteriovenous Fistula: An Intraoperative Change in the Preoperative Plan.

Regarding coronary artery bypass grafting (CABG) in patients on hemodialysis, in situ internal thoracic artery (ITA) grafting of the left anterior descending artery (LAD) improves survival and freedom from cardiac events. Although a problem with the ITA can possibly occur, using the ITA ipsilateral to an arteriovenous fistula (AVF) in the upper extremity of patients on hemodialysis can cause coronary subclavian steal syndrome (CSSS). CSSS is a condition of myocardial ischemia caused by the diversion of blood flow from the ITA following coronary artery bypass surgery. CSSS has been reported to occur in cases of subclavian artery stenosis, AVF, and low cardiac function. A 78-year-old man with end-stage renal disease experienced angina pectoris during hemodialysis. The patient was scheduled for CABG, including anastomosis of the left internal thoracic artery (LITA) and LAD. After completion of all anastomoses, the LAD graft demonstrated retrograde blood flow, suggestive of ITA anomalies or CSSS. The LITA graft was transected at the proximal part and anastomosed to the saphenous vein graft with sufficient flow to the high lateral branch eventually.

Partial Arch Replacement Using Common Trunk Perfusion in Type A Acute Aortic Dissection.

An 80-year-old woman was referred to our hospital following a syncope. Contrast-enhanced computed tomography revealed an acute type A aortic dissection with a bovine aortic arch and an enlarged innominate artery. The dissection affected only the ascending aorta and not the common trunk, which is composed of the innominate and left common carotid arteries. Cardiopulmonary bypass was established using common trunk perfusion and vena cava drainage. Following a thorough evaluation, a surgical intervention involving the replacement of the ascending aorta and partial arch, accompanied by the excision of the dilated innominate artery, was meticulously carried out. In instances where the common trunk remains unaffected by the dissection, it presents as a viable alternative perfusion site. Therefore, opting for an approach involving the resection of the common trunk followed by the separate reconstruction of the innominate and left common carotid arteries during the replacement of the ascending aorta and partial arch may serve as a preventative measure against potential vascular events in the future.

Propensity score analysis comparing off-pump versus on-pump coronary artery bypass grafting in older adults.

OBJECTIVE: This study aimed to compare the results of off-pump and on-pump coronary artery bypass grafting in older adults and to examine early and late outcomes. METHODS: This study included 226 patients aged ≥ 75 years who underwent isolated coronary artery bypass grafting. Of these, 141 and 85 patients were included in the off-pump and on-pump groups, respectively. Propensity scores were calculated for each case, matched, and compared between the two groups (68 cases in each group), along with mid-term outcomes of survival and major adverse cardiac events. RESULTS: Operative time, red blood cell transfusion volume, and postoperative hospital stay duration were significantly higher in the on-pump group (267 vs 370 min, P < 0.001; 4.3 vs 17.2 units, P < 0.001; and 20.8 vs 35.8 days, P = 0.012, respectively). Postoperative occurrence of new atrial fibrillation was significantly higher in the on-pump group (4.4% vs 27.9%, P < 0.001), and Kaplan-Meier survival analysis showed a significantly worse prognosis in the on-pump group than in the off-pump group (3-year survival rate 90.7% vs 71.5%, log rank P = 0.007). However, there was no statistically significant difference in cardiovascular-related deaths (log rank P = 0.07). CONCLUSIONS: On-pump coronary artery bypass grafting in an older adult population resulted in increased transfusion volume and postoperative occurrence of atrial fibrillation. The mid-term postoperative outcomes were also poorer with on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting reduced future all-cause deaths in older adults.

Retrograde Type A Acute Aortic Dissection With Cerebral Malperfusion Six Years After Thoracic Endovascular Aortic Repair.

A 59-year-old male with prior thoracic endovascular aortic repair presented with altered mental status. Magnetic resonance imaging showed cerebral infarction, and subsequent computed tomography revealed acute type A aortic dissection and right carotid artery occlusion. He underwent total arch replacement with right carotid artery bypass. After successful intervention, he was transferred to a rehabilitation facility for further improvement.

DeBakey Type II Acute Aortic Dissection Distant From the Proximal Edge of a Stent Graft: A Case Report Nine Years After Thoracic Endovascular Aortic Repair.

An 84-year-old male with a medical history notable for prior thoracic endovascular aortic repair for thoracic aneurysm nine years ago presented to the emergency department with a chief complaint of transient loss of consciousness. A brain computed tomography showed no remarkable findings. A subsequent computed tomography scan for comprehensive evaluation revealed DeBakey type II acute aortic dissection as evidenced by contrast-enhanced imaging. An intimal tear was found on the ascending aorta distant from the proximal edge of a stent graft. Due to the urgency of the situation, the patient underwent emergent ascending aortic replacement. Following the successful intervention, the patient was transferred to a specialized rehabilitation facility with the goal of facilitating further improvement in their condition.

Determining Infected Aortic Aneurysm Treatment Using Focused Detection of Helicobacter cinaedi.

We detected Helicobacter cinaedi in 4 of 10 patients with infected aortic aneurysms diagnosed using blood or tissue culture in Aichi, Japan, during September 2017-January 2021. Infected aortic aneurysms caused by H. cinaedi had a higher detection rate and better results after treatment than previously reported, without recurrent infection.
