1/38. Repair of type IV thoracoabdominal aneurysm with a combined endovascular and surgical approach.We report an unusual case of type IV Thoracoabdominal Aneurysm (TAA) with Superior Mesenteric Artery (SMA), celiac artery, and bilateral renal artery aneurysms in a patient who underwent an earlier repair of two infrarenal Abdominal aortic aneurysm (AAA) ruptures. Because of the presence of the visceral artery aneurysms and the earlier operation through the retroperitoneum, standard surgical treatment via a retroperitoneal approach with an inclusion grafting technique was considered difficult. A combined surgical approach achieving retrograde perfusion of all four visceral vessels and endovascular grafting allowing exclusion of the TAA was accomplished. Complete exclusion of the aneurysm and normal perfusion of the patient's viscera was documented by means of follow-up examinations at 3 and 6 months. The repair of a type IV TAA with a Combined Endovascular and Surgical Approach (CESA) allowed us to manage both the aortic and visceral aneurysms without thoracotomy or re-do retroperitoneal exposure and minimized visceral ischemia time. If the durability of this approach is confirmed, it may represent an attractive alternative in patients with aneurysmal involvement of the visceral segment of the aorta.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/38. Atherosclerotic disruption of the aortic arch during coronary artery bypass operation.A 70-year-old-man presented with a symptomatic three vessel coronary artery disease and was scheduled for myocardial revascularization. During extracorporeal circulation an intrathoracal bleeding occurred and aortic rupture was suspected. An iatrogenic plaque rupture in the concavity of the aortic arch was found due to cannulation attempts. The aortic arch was grafted in the so-called elephant trunk technique. Thereafter bypass grafts were anastomosed to the stenosed coronary arteries. The patient was discharged from hospital after 2 weeks in good condition.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/38. Replacement of the entire thoracic aorta according to the reversed Elephant Trunk technique.The aim of this work is to present our modified Elephant Trunk technique to reduce circulatory arrest time and consequently mortality and morbidity rates. According to Borst's technique the ascending aorta and aortic arch are replaced first, under deep hypothermic circulatory arrest, while a graft segment is left in the descending thoracic aorta. In the second stage of the operation, the descending thoracic aorta is replaced through left thoracotomy using this graft segment. In our modified technique, after the flexion in the proximal segment of the graft, the descending thoracic aorta is replaced first through left thoracotomy in Bio-Pump protection, choosing the best aortic segment for proximal anastomosis. In the second stage we replace the ascending aorta and the aortic arch using the graft and applying Carrel patch anastamosis only to the epiaortic vessels, under deep hypothermic circulatory arrest. It is our opinion that the mortality incidence of this technique is similar to that obtained with Borst's technique, though certainly inferior to the one stage procedure , while the morbidity results are better than those obtained with the Borst Elephant Trunk technique and with the one stage procedure. In fact there are fewer stroke incidents thanks to the reduced times of deep hypothermic circulatory arrest, and fewer postoperative bleedings and respiratory failures thanks to the reduced times of the total cardiopulmonary bypass. At the beginning we used this technique to replace symptomatic aneurysms, covered ruptures, and hematomas of the wall of the descending thoracic aorta, which required replacement of the descending thoracic aorta first; we later extended the treatment to all types of thoracic aorta aneurysms.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/38. Delayed aortic rupture caused by an implanted anterior spinal device. Case report.The authors describe a case of delayed aortic rupture following the application of a smooth-rod Kaneda (SRK) instrument. This is a rare but critical complication of anterior spinal fusion in which instrumentation is placed, and the authors wish to draw attention to the possible complications arising from such surgery. A few cases of this complication were reported in 1986. No reports have been published since then; perhaps because techniques and implant design have improved. In this case, a 53-year-old man suffered a T-11 fracture and related paraparesis, and he underwent decompression and anterior fusion in which an iliac bone graft was placed using an SRK device. Although his neurological deficit resolved postoperatively, nonunion of the grafted bone caused progressive kyphosis of the thoracolumbar spine. Twenty months after surgery, he complained of progressive gastrointestinal symptoms, and a delayed aortic rupture with a pseudoaneurysm was found surrounding the implant. The aortic pseudoaneurysm was replaced with an artificial vessel, and the SRK device was removed immediately. Delayed aortic rupture associated with anterior instrumentation is extremely rare but can occur. Even if the design of the implants can be improved, the placement of implants near the aorta and subsequent changes in the close anatomical relationship between the aorta and the implant eventually may result in this life-threatening complication. Careful follow-up examination and early removal of the implant, if necessary, are important.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/38. Subtotal thoracic aortic replacement as reoperation for ruptured aortic dissection: report of a case.We report successful repair of a ruptured chronic aortic dissection in a 63-year-old female who had undergone end-to-end anastomosis for acute type A dissection 8 years before. The patient had hypotension with back pain and cough. A computed tomogram revealed a large chronic aortic dissection (Stanford type A) and complete atelectasis of the left lung due to hemothorax. The brachiocephalic artery was also dissected and aneurysmal. Emergency surgery was performed. Subtotal thoracic aortic replacement with reconstruction of 4 cervical vessels was carried out using hypothermic circulatory arrest with selective cerebral perfusion via a redo-sternotomy and a left anterolateral thoracotomy. The patient was discharged from the hospital without any sequelae.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/38. Complex, traumatic rupture of the thoracic aorta in a child: diagnostic findings and delayed surgery.We report the unusual case of a 4-year-old girl with traumatic aortic rupture. A conventional chest X-ray showed an enlarged mediastinum. Spiral CT and transthoracic echocardiography demonstrated a mediastinal hematoma, bilateral pleural effusion, and a rupture of the aortic arch. Semi-elective surgery, 4 days after the accident, confirmed rupture of the aortic arch with dislocation of the left carotid artery and the Ductus of Botalli. The vessels were subsequently repaired without complication. After a follow-up of 10 months, the child has fully recovered.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/38. Bilateral subclavian arterial aneurysm and ruptured abdominal aorta pseudoaneurysm in Behcet's disease.Behcet's disease is characterized by recurrent ulcers of the mouth and genitalia and relapsing iritis. It is recognized as a chronic multisystem disease affecting the skin, mucous membranes, eye, joints, central nervous system, and blood vessels. About 8% of the patients with Behcet's disease have severe vascular complications such as arterial aneurysm and occlusion. In our patient, there was a massive, painful, pulsatile mass on the clavicle on the right side of neck. A left subclavian artery aneurysm mass was observed on the left apex on a chest X-ray. Through angiography, a lobular giant saccular aneurysm on the proximal side of the right subclavian artery, giant aneurysm on the left subclavian artery, and occlusion on the left subclavian-axillary artery were observed. We treated first the right and then the left subclavian arterial aneurysm with a two-stage operation. The aneurysms were resected and polytetrafluoroethylene (PTFE) graft interposition was performed. Control angiography was performed 6 months postoperatively. Both grafts were open and there was no anastomotic aneurysm. The patient was reoperated on for a ruptured abdominal aorta pseudoaneurysm 13 months after the first operation. The aortic defect was repaired using a Dacron patch.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/38. Prehospital rounds. The quick stop.The coroner's post-mortem examination revealed a tom aorta. This case illustrates that although a patient may appear stable, a major catastrophic event may nonetheless be taking place. How many times have we responded to MVAs similar to the one described here and seen those involved deny injuries? We carry a higher suspicion of aortic injury after someone has been ejected from a vehicle or involved in a high-speed crash. That's not always the case, however, and understanding how internal organs respond to high-speed impacts is crucial. Damage to the aorta may result after a sudden deceleration injury of any type: a fall, vehicle crash or violence. The most common forms of traumatic aortic injury occur where the aorta is "tethered" in place: at its intersection with the heart and at its distal portion just beneath the left subclavian artery near the ligamenta arteriosum. Approximately 80% of patients with aortic injury die at the scene. The injury may be hidden in the other 20%, but they have the potential to rapidly deteriorate and die. Those who survive typically are at a trauma center and are cared for by providers who have a suspicion of the injury. A high index of suspicion should be maintained on all rapid-deceleration injuries and with patients who experience chest pain, dyspnea, a difference in pressure between the upper and lower extremities, and paralysis. paralysis can occur when aortic injury cuts off blood supply [table: see text] to the spinal cord. The spinal cord obtains its blood supply from arteries coming directly off the aorta, and a torn aorta can shear off these vessels, leaving the spinal cord to infarct and the patient to lose all distal function. When a victim sustains a sudden-deceleration injury to the chest, signs of aortic injury should be sought. It is imperative to maintain a high index of suspicion throughout patient care and be aware that although a patient may appear to be quite stable, the reality might be otherwise, and rapid transport to a trauma center will be necessary to save their life.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/38. Massive hematuria after cystoscopy in a patient with an internal iliac artery aneurysm.An unusual case is reported here of a patient with internal iliac artery aneurysm who developed massive hematuria after cystoscopic examination. A 75-year-old man presented with asymptomatic gross hematuria. Cystoscopic examination revealed that the bladder neck was congested and that the right-side wall was being pressed on by an extrinsic mass. Computed tomography showed a right internal iliac artery aneurysm and tortuous perivesical vessels. Three days after the cystoscopic examination the patient suffered massive hematuria. hemorrhage due to an arteriovesical or arterio-ureteral fistula secondary to rupture of the internal iliac artery aneurysm was suspected, and an emergency operation was performed. At operation the aneurysm had not ruptured but overswelling perivesical vessels were found to have developed, and these fed a high blood flow to the bladder neck. In the present case cystoscopic examination injured the mucosa and led to massive hemorrhage from the bladder neck.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
10/38. Treatment of thoracoabdominal aortic aneurysms with a combined endovascular and surgical approach.AIM: The conventional approach for the repair of thoracoabdominal aneurysms remains complex and demanding and is associated with substantial morbidity and mortality. Moreover, in cases of reoperation the impact can be dramatic either in survival or in quality of life of the patients, albeit the use of adjuncts. A combined endovascular and surgical approach with retrograde perfusion of visceral and renal vessels has been realized in order to minimize intraoperative and postoperative complications. methods: Within an experience of 231 aortic stent-grafts between 1995-2000, 4 of the patients with thoracoabdominal aneurysms were treated with a combined endovascular and surgical approach. Three procedures were electively conducted and 1 on emergency basis. Two women, 59 and 68 years old, and 2 men, 68 and 73 years old (maximum aneurysm's diameter was 10, 6, 8 and 9 cm, respectively) were operated with the combined method (the first 2 patients had a previous open repair of a thoracoabdominal aneurysm). The surgical approach was executed in all patients without thoracotomy or re-do retroperitoneal exposure. Revascularization of renal, superior mesenteric (and celiac in 2 cases) arteries was accomplished via transperitoneal bypass grafting. Aneurysmal exclusion was performed by stent-graft deployment. RESULTS: The entire procedure was technically successful in all patients. The 1(st) patient was discharged 6 weeks after the operation, while the postoperative studies revealed the patency of the vessels and no evidence of leak or secondary rupture of the aneurysm; the patient died 3 months after the repair, due to rupture of an aneurysm of the ascending aorta. In the 2(nd) patient, 30 months after the operation, spiral-CT scanning revealed distinct shrinkage of the aneurysm, no graft migration or endoleak and patency of all revascularized vessels. The 3(rd) patient died on the 6th postoperative day due to multiorgan failure after having developed ischemic-related pancreatitis, albeit the successful combined repair. The 4(th) patient followed an uneventful course. No patient experienced any temporary or permanent neurological deficit. CONCLUSION: The combined endovascular and surgical approach is feasible, without cross-clamping of the aorta and with minimized ischemia time for renal and visceral arteries, and seems the appropriate strategy for high risk and previously operated, with a thoracoabdominal trans-diaphragmatic approach, patients.- - - - - - - - - - ranking = 3keywords = vessel (Clic here for more details about this article) |
