Few patients with traumatic aortic laceration remain undiagnosed and survive long enough to develop a chronic aneurysm. Such aneurysms are frequently asymptomatic: alternatively, they may manifest chest pain, dysphagia, bronchial irritation, or sudden death. A case of aortobronchial fistula secondary to a chronic post-traumatic aneurysm of the aortic isthmus is presented. Hemoptysis was the main sign. The affected segment of the thoracic aorta was repaired with a Hemashield patch and a left upper lobectomy was performed.

Ascending aortic aneurysms are usually treated with graft replacement under cardiopulmonary bypass. However, if a candidate for off-pump coronary artery bypass grafting has an enlarged ascending aorta, surgeons may consider wrapping it without cardiopulmonary bypass. Here, we report a 78-year-old female who underwent successful wrapping of the ascending aorta concomitant with off-pump coronary artery bypass grafting, using a new wrapping technique that involves multiple bootstraps.

The treatment of aortic aneurysm of ascending aorta has been fraught with difficult surgical problems. For the most part, these were resolved in 1968 with the introduction of a technique of total replacement of ascending aorta and reimplantation of the coronary arteries by Bentall and De Bono. This technique however, with all of its advantages, caries a certain problems. In chronic dissecting aneurysms, there is frequently a marked disparity in circumference between the true and false lumen distally. Distal perfusion is directed into both the true and false lumens by removing segment of the septum between the two lumens and constructing the distal graft anastomosis is to the outer layer of aortic adventitia. The distal false lumen, aortic branches and fenestrations have matured and healed in most cases. And importantly, major aortic tributaries may be solely dependent on the false lumen for perfusion. We are presenting two cases of chronic dissecting aneurysm of ascending aorta with aortic regurgitation, who have good result by surgical correction of so-called Bentall procedure with maintenance of blood flow directed into both true and false lumen.

Complete circulatory arrest with profound hypothermia has been an indispensable adjunct to the safe management of selected giant intracranial aneurysms. For the conduct of cardiopulmonary bypass, there are usually two kinds of methods, open and closed chest methods. We could manage one case of huge intracranial aneurysm that was successfully operated under circulatory arrest using the closed chest method, especially with percutaneous insertion of arterial and venous cannulas for cardiopulmonary bypass.

After the first report of mitral stenosis as a cause of recurrent laryngeal nerve palsy by Ortner in 1897, many authors have described that some kinds of cardiovascular disease might contribute to the development of recurrent laryngeal nerve palsy. The estimated rate of aortic aneurysm related with recurrent laryngeal nerve palsy is about 5%. Aortic aneurysm is classified into 3 types according to the involving segment of aorta in which aneurysms develop, and the first class-aneurysm in ascending aorta and aortic arch-is known to be the only type related to recurrent laryngeal nerve palsy. Recently we experienced two cases of recurrent laryngeal nerve palsy each of which had aneurysm on aortic arch as a major contributing factor. We report these cases with brief review of the literature.

A 28-year-old woman was referred to our hospital with a sudden, very severe headache. Brain computed tomographic angiography showed a saccular cerebral aneurysm at the bifurcation of the left middle cerebral artery and infraoptic courses of both anterior cerebral arteries. The anterior cerebral arteries were seen to arise from the ipsilateral internal cerebral arteries at the level of the origin of the ophthalmic artery, passed underneath the ipsilateral optic nerve, and turned upward at ventral portion of the optic chiasm. Infraoptic course of the proximal anterior cerebral artery is an extremely rare anomaly and is often associated with cerebral aneurysms. We report the clinical features, radiological findings, and possible genesis of this anomaly with a literature review.

Over the past 11 years, from Jan. 1975 through Nov. 1985, 27 consecutive patients with congenital aneurysms of sinus of Valsalva underwent corrective surgery in our department of Thoracic Surgery. 26 were suggested to arise from right coronary sinus and 1 from noncoronary sinus: among 26, 18 ruptured into right ventricle, 1 into right atrium, 1 into pulmonary artery. And 1 from noncoronary sinus into right atrium. Among 18 cases of preoperatively diagnosed as ruptured aneurysm, the fistula was repaired through the aorta in 12, although the chamber of termination was also opened in some. Recurrent fistula occurred in 2 cases in which the ruptured aneurysm was repaired through right ventricle. It appears that repair of the fistula itself is best carried out through an aortotomy, after cross-clamping.

We experienced 20 cases of acquired aortic diseases during last 1 year [Sep. 1992-Aug. 1993] with newly developed surgical strategies. There were 13 cases[65%] of aortic dissections, 5 cases[25%] of aortic aneurysms and 2 cases of Takayasu arteritis with mean age of 56 + 16 years[range:5-78].In ten cases of patients requiring ascending aortic replacement, femoral artery and femoral vein &/or RA auricle were used as cannulation site. With deep hypothermic circulatory arrest and retrograde cerebral perfusion of cold oxygenated blood via SVC, we can replace the ascending aorta and part of arch if necessary. The mean duration of circulatory arrest was 30 minutes[17-45 min]. In 5 cases of patients who requiring descending and thoracoabdominal aorta replacement, we used simple aortic crossclamping under normothermia with no heparin. The mean duration of aortic crossclamping was 37 minutes[25-50 min].The results of operation were as follow:Operative mortality[2 cases, 10%], delayed cerebral infarct[1], low extremity weakness[1] and intraoperative myocardial infarct[1]. There are no delayed complication or mortality as yet.

"Stunning" represents prolonged contractile depression of any muscular component after alleviation of severe ischemia, as shown in reperfusion following acute myocardial ischemia or ischemic stroke. Clinically, it presents with no or delayed recovery past to thrombolytic therapy but its pathogenic mechanism is not fully uncovered yet. We describe a unique case of a 63-year-old woman, who was undertaken endovascular coiling for the aneurysms, deteriorated several hours later without known cause, and showed delayed clinical improvement over the next 3 days following thrombolysis. Immediate post-thrombolysis magnetic resonance imaging scan showed no apparent abnormality except for high signal intensity within the corresponding hemisphere. Reversible but delayed nature of " brain stunning" can be explained by these images and it seems to be caused by a certain type of reperfusion injury.

Pure sylvian fissure arteriovenous malformations[AVMs] are vascular malformations confined to the sylvian fissure without parenchymal involvement. Surgical removal is regarded as difficult because the nidus is located just lateral to important structures such as the basal ganglia and the internal capsule. Because most feeding arteries to the nidus are branches of the middle cerebral artery[MCA], differentiation between these feeders from en passant and normal vessels is of great importance in order to reduce morbidity and mortality from surgical intervention. We report a case of pure sylvian fissure AVM who presented with an intra-temporal lobe hematoma that was located around venous aneurysms distant from the nidus. The clinical characteristics of this AVM and the surgical methods employed to avoid complications are discussed.
