Aortic dilatation and dissection are severe complications during pregnancy that can be fatal to both the mother and the fetus. The risks of these complications are especially high in pregnant patients with Marfan syndrome; however, incidents of descending aortic dissection are very rare. This case report involves a successful Bentall procedure for and recovery from a rare aortic dissection in a pregnant Marfan patient who developed acute type II aortic dissection with severe aortic regurgitation and chronic descending aortic dissection immediately after Cesarean section. Regular follow-up will be needed to monitor the descending aortic dissection.

Background: Complicated acute type B aortic dissection is a life-threatening condition with high morbidity and mortality. The aim of this study was to report a single-center experience with endovascular stent-graft repair of acute type B dissection of the thoracic aorta and to evaluate the mid-term outcomes. Methods: We reviewed 18 patients treated for complicated acute type B aortic dissection by thoracic endovascular aortic repair (TEVAR) from September 2011 to July 2017. The indications for surgery included rupture, impending rupture, limb ischemia, visceral malperfusion, and paraplegia. The median follow-up was 34.50 months (range, 12-80 months). Results: The median interval from aortic dissection to TEVAR was 5.50 days (range, 0-32 days). There was no in-hospital mortality. All cases of malperfusion improved except for 1 patient. The morbidities included endoleak in 2 patients (11.1%), stroke in 3 patients (16.7%), pneumonia in 2 patients (11.1%), transient ischemia of the left arm in 1 patient (5.6%), and temporary visceral ischemia in 1 patient (5.6%). Postoperative computed tomography angiography at 1 year showed complete thrombosis of the false lumen in 15 patients (83.3%). Conclusion: TEVAR of complicated type B aortic dissection with a stent-graft was effective, with a low morbidity and mortality rate.

Aortic dissection is an uncommon, life-threatening medical emergency that is associated with a high mortality rate, and death from aortic dissection is mainly related to secondary complications, namely cardiac tamponade, severe aortic regurgitation, acute myocardial infarction, and abdominal organ vessel obstruction. Hence, prompt and accurate diagnosis followed by proper treatment is important for patient survival. Herein, we present a rare case of sudden death after aortic dissection with concomitant acute myocardial infarction and cardiac tamponade.

The most common symptom of aortic dissection is chest pain, which is similar to acute coronary artery syndrome, making it difficult to diagnose with clinical pattern, requiring various diagnostic methods. About 10-15% of the aortic dissection patients are accompanied by changes in the ST segment by the dissecting flap of the coronary opening, which can lead to delayed diagnosis of aortic dissection, or can adversely affect the patient by administration to unnecessary drugs such as nitroglycerin, thrombolytic agent, and anticoagulants. It is difficult to distinguish aortic dissection from an acute myocardial infarction only through a 12-Lead electrocardiogram at the pre-hospital. The application of cardiac ultrasonography through medical direction to chest pain patients who show ST segmental changes in pre-hospital phase will contribute to the diagnosis of aortic dissection and the improvement of survival rate, such as anticoagulant administration, to patients with acute myocardial infarction.

A 67-year-old female patient was treated with conventional total arch replacement and insertion of a stented elephant trunk (SET) graft into the descending thoracic aorta for acute DeBakey type I aortic dissection at one time. She had been treated with right coronary artery stent insertion for acute myocardial infarct 4 days earlier, and at that time, she was diagnosed with acute DeBakey type I aortic dissection from the ascending aorta to the suprarenal artery based on trans-esophageal echocardiography and aorta computed tomography. Through a median sternotomy, we inserted the SET graft through the opened aorta to the descending aorta. We also performed anastomosis between the proximal stented graft and the distal aortic arch, and then performed total arch replacement. For acute DeBakey type I aortic dissection, we report total arch replacement with insertion of a SET graft as a combination of conventional surgery and the interventional technique.

Acute complicated type B aortic dissection (TBAD) is a potentially catastrophic, life-threatening condition. If left untreated, there is a high risk of aortic rupture, irreversible organ or limb damage, or death. Several risk factors have been associated with acute complicated TBAD, including age and refractory hypertension. In the acute phase, even uncomplicated patients are more prone to develop complications if hypertension and pain are left medically untreated. Innovations in stent graft technologies have incrementally improved outcomes since their first use for this condition in 1999, though improvement is needed in mitigating periprocedural complications, adverse events, and mortality. In the past decade, endovascular repair has become the preferred treatment because of its superior outcomes to open repair and medical therapy. The Valiant Captivia Thoracic Stent Graft System is a third-generation endovascular stent graft with advancements in minimally invasive delivery, conformability to the anatomy, and the minimization of adverse sequelae. Herein, this stent graft is briefly reviewed and its 3-year outcomes are presented. Freedom from all-cause and dissection-related mortality was 79.1% and 90.0%, respectiv ely. The Valiant Captiv ia Stent Graft represents a safe, effective intervention for acute complicated TBAD. Continued surveillance is needed to verify its longer-term durability.

We report a case of aortic dissection masquerading as acute ischemic stroke followed by intravenous thrombolysis. A 59-year-old man presented with dizziness. After examination, the patient had a seizure with bilateral Babinski signs. Soon after identifying multiple acute infarctions in both hemispheres on diffusion-weighted brain magnetic resonance (MR) imaging, tissue plasminogen activator (t-PA) was administered. Both common carotid arteries were invisible on MR angiography, and subsequent chest computed tomography revealed an aortic dissection. The emergency operation was delayed for 13 hours due to t-PA administration. The patient died of massive bleeding.

A 50 year old man with acute aortic dissection DeBakey type I, involving right coronary artery and aortic valve, underwent replacement of the ascending aorta and aorto-right coronary bypass grafting. The operative findings showed a large transverse intimal tear was at about 4cm above the aortic valve. The dissection extended out into the proximal right coronary artery. And we found that the right coronary artery originated from the left sinus of Valsalva, run transversally in the aortic wall, with partial rupture. Postoperatively he had no ischemic cardiac symptoms and neurologic complications. He was discharged on postoperative 9th day with good result.

Acute mediastinitis and subsequent graft infection following aorta surgery poses a difficult problem, as infected synthetic material must be completely removed for resolution of infection. Here we report a case of successful management of acute mediastinitis following hemiarch replacement for acute aortic dissection with omental flap transfer leaving infected graft in situ.

Since the operative mortality rate of the Acute aortic dissection has been reducing, a more extensive primary repair of the dissected aorta is preferred for acute aortic dissection to reduce the needs of secondary procedures. We performed a total aortic arch replacement with distal stent-grafting in acute type A aortic dissection. The patient was a 50-years old man. He recovered from the operation and was followed up for 7 months. The pseudolumen in the descending aorta was obliterated with the stent.
