Repeated transluminal endovascular Inoue stent graft placement for progressive dilatation of prosthetic graft that had been repaired with Inoue stent graft placement for dilatation 23 years after extraanatomical bypass

A 76-year-old man had undergone aneurysm exclusion and ascending abdominal aortic extraanatomical bypass for a thoracoabdominal aortic aneurysm in 1978. In 1983 hemoptysis occurred, and resection and closure of the central stump of the aorta and a left lower lobectomy were performed. Dilatation (ϕ50 mm) of a prosthetic graft (Cooley Graft ϕ18 mm) used for extraanatomical bypass was noted in 2001 and was repaired by placement of an Inoue stent graft. However, the aneurysm diameter increased further (ϕ70 mm), although no endoleak was noted: Placement of an Inoue stent graft covering the whole length of the prosthetic graft was repeated in 2006. The postoperative course was smooth, no endoleak occurred, and the patient was discharged 2 weeks after surgery.     

Surgical treatment for coronary artery aneurysm

Two successful cases of the surgical treatment for coronary artery aneurysm (non-Kawasaki disease) were reported. The first case had a saccular aneurysm on the left circumflex coronary artery (LCx) #14. Resection of the LCx aneurysm was performed subsequent to single vessel coronary artery bypass grafting (CABG) to the distal portion of LCx#14 under the cardioplegic cardiac arrest. The second case had aneurysms on both the left anterior descending artery (LAD) #7 (fusiform) and the LCx#11 (saccular). After double vessel CABG to LAD#7 and LCx#11, ligation or resection of two aneurysms was performed successfully. Postoperative courses have been uneventful with good angiographic results achieved. Since these surgical procedures demonstrated safety, the patients are expected to achieve a good long-term prognosis.     

Left thoracotomy approach in reoperative off-pump coronary revascularization

Objective: Reoperative coronary bypass grafting is at high risk. Particularly in redo cases where the patent graft is running near the midline of the sternum, the graft may be exposed to injury by a median sternotomy and subsequent dissection. Whereas, off-pump bypass grafting from the left axillary artery or descending thoracic artery by a left thoracotomy approach is safe for preventing graft damage.Methods: From March 1998 to February 2002, we performed off-pump coronary artery bypass grafting by a left thoracotomy approach in 9 patients. The left axillary artery was used as the inflow vessel in 4 cases, and the descending thoracic, aorta in 5.Results: The radial artery was anastomosed proximally to the axillary artery in 4 cases and the descending thoracic aorta in one case. The saphenous vein graft was anastomosed, proximally to the descending thoracic aorta in 4 cases. Transdiaphragmatic minimally invasive bypass grafting for the right coronary artery was simultaneously performed in 3 cases. Postoperative cardiac events were ventricular arrhythmia in 6 cases and supraventricular arrhythmia in 3 cases. There was no damage to the patent grafts. Postoperative coronary angiography performed, in 8 cases revealed all the grafts to be patent without stenosis. Cardiac symptoms were not found after the operation in any of the cases.Conclusions: These procedures can prevent the injury to patent grafts caused by a median sternotomy, and will be one of the useful strategies for reoperative off-pump coronary artery bypass grafting.

Vascular complications after surgical repair of aneurysms in Behçet's disease

The poor prognosis of vasculo Behcet's disease is often due to postoperative vascular complications (false aneurysm and graft occlusion). We report a case of an abdominal aortic aneurysm associated with an aneurysm of the left common femoral artery in a 23-year-old Portuguese man. The primary treatment was surgical (aneurysmectomy and prosthetic revascularization). The early occlusion of the left femoral revascularized artery was treated surgically with a new bypass. The occlusion of the right limb of the aortoiliac graft was asymptomatic and was not treated. Two months after admission to our hospital, the stenosis of the infrarenal aorta successfully treated by angioplasty via the occluded right limb of the graft. The patient was followed up for 18 months. He could only walk a short distance and had rest pain in the left foot. Magnetic resonance angiography showed a false aneurysm of the infrarenal aorta, and an occlusion of the remaining left limb of the aortoiliac graft. The endovascular treatment performed does not avoid the need for surgical treatment, because occlusion and false aneurysm may occur after dilatation. The endovascular approach can also be used during a sudden inflammatory surge, and makes it possible to wait for a quiescent period when surgery can be performed.

Proximal clipping and bypass between bilateral vertebral arteries using a radial arterial graft for the treatment of a dissecting aneurysm of the vertebral artery

Proximal clipping has been performed recently as the main surgical treatment for a dissecting aneurysm of the vertebral artery. When there is a contralateral vertebral artery of a smaller size with arteriosclerotic changes, some form of bypass to prevent cerebellar and brain stem infarction is needed in addition to proximal clipping. We treated a 50-year-old man with a ruptured dissecting aneurysm of the left vertebral artery and stenosis at the V3 segment of the right vertebral artery. The caliber of the right vertebral artery was smaller than the left. After an anastomosis between bilateral vetebral arteries using a radial arterial graft, dissecting aneurysm was clipped at the proximal portion of the aneurysm.     

Coronary artery aneurysm in a patient with Marfan syndrome

True aneurysm of the coronary artery in Marfan syndrome is very rare. We present a patient with Marfan syndrome who had aneurysms from the ascending aorta to the thoracoabdominal aorta and a large aneurysm of the left main coronary artery after an original Bentall operation. Prosthetic graft replacement of total aorta, coronary artery bypass grafting, and removal of the aneurysm of the left main coronary artery were successfully performed.     

Surgical treatment for cervical aortic arch with aneurysm formation

Cervical aortic arch is an unusual malformation. Cervical aortic arch with aneurysm formation is very rare. We report a case of cervical aortic arch associated with a saccular aneurysm in a 59-year-old Japanese man. The aneurysm protruded caudally and was located between the left common carotid and left subclavian arteries. Cardiopulmonary bypass and deep hypothermic circulatory arrest was applied as adjunct methods. A Dacron graft was sutured just distal to the left common carotid artery, with the patient in the Trendelenburg position. The proximal site was left open while oxygen-saturated venous blood was supplied in a retrograde manner to perfuse the lower body during occlusion of the descending aorta. Distal anastomosis to the descending aorta was performed during rewarming. The left subclavian artery was reconstructed by using a branch of the graft. This procedure is simple and useful for distal arch operations, especially in patients with Haughton D type aneurysms.

Staged repair for a chronic dissecting thoracic aortic aneurysm with no transfusion in a Jehovah's Witness patient

We present the case of a 59-year-old male Jehovah's Witness who underwent staged repair for a thoracic aortic aneurysm with no transfusion. The primary operation to replace the distal portion of the aortic arch and left subclavian artery reconstruction were performed. We applied axilla–femoral artery temporary external bypass. A second operation was carried out 8 months later. We replaced the descending aorta and reconstructed the intercostal arteries under temporary bypass in the same manner as was done during the previous operation. The blood losses and minimum hemoglobin values during the two operations were 2235 and 13 941 ml, respectively, 8.8 and 5.9 g/dl, respectively. Administration of erythropoietin and a drainage blood recovery device were useful. Surgical repair for a thoracic aortic aneurysm using a temporary bypass is thus considered a viable surgical option in such situations and is important for conducting effective perioperative management.     

Arterio-intestinal fistula as a complication following insertion of an aorto-iliac bifurcation graft. A case report

A patient who had been treated with insertion of an aorto-iliac bifurcation dacron prosthesis for atherosclerosis 6 years previously, developed a fistulous communication between a false aneurysm at the distal anastomosis to the left iliac artery and an ileal loop. Intestinal haemorrhage and signs of infection were the main symptoms. Successful surgical treatment consisted of suturing the intestinal defect, removal of the left limb of the graft and vascular reconstruction by means of a subcutaneous femorofemoral vein bypass.

Simultaneous Minimally Invasive Direct Coronary Artery Bypass and Repair of a Penetrating Atherosclerotic Ulcer of the Descending Thoracic Aorta: Report of a Case

A 70-year-old man with a descending aortic aneurysm was admitted to the hospital because of an abnormal chest X-ray. The chest computed tomography and magnetic resonance angiography findings showed a saccular aneurysm at the descending thoracic aorta. A preoperative coronary arteriogram showed 75% stenosis of the left anterior descending coronary artery and 99% stenosis of the right coronary artery. A simultaneous minimally invasive direct coronary artery bypass (MIDCAB for two vessels) and a descending aortic aneurysm repair were performed without any complications. A pathological examination showed the aneurysm to be a pseudoaneurysm originating from a penetrating atherosclerotic ulcer. Received: December 25, 2000 / Accepted: July 17, 2001     

Profunda Femoris as an Access Site Vessel for a Hybrid Approach to the Treatment of a Para-Anastomotic Common Iliac Artery Aneurysm and Intermittent Claudication,Occurring after Previous Abdominal Aortic Tube Graft Repair and Femoro-Femoral Bypass Graft. A Case Report

A true para-anastomotic right common iliac artery aneurysm and intermittent claudication developed in a 76-year-old man 5 years after open abdominal aortic aneurysm repair with a Dacron tube graft. Following the initial operation the patient developed acute left iliac occlusive disease necessitating an immediate right-to-left femoro-femoral crossover bypass graft. The patient was a poor open surgical candidate because of multiple medical comorbidities. Therefore, a hybrid approach was used consisting of exposure and catheterization of the right profunda femoris artery, which was used as the access site vessel for the deployment of a covered stent graft extending from the ostium of the common iliac artery into the external iliac artery. Simultaneously, the right profunda femoris provided inflow for an open above-knee profunda femoro-popliteal bypass graft to perfuse the right lower extremity. Postoperative angiography demonstrated primary technical success, with exclusion of the aneurysm and no endoleak. The patient is doing well 34 months postoperatively, with a patent endograft and no sign of intermittent claudication. Profunda femoris proved to be an excellent alternative to the common femoral artery for the application of a hybrid technique in a high-risk patient with complicated anatomy.     

Endovascular Stent-Grafts for Aneurysms of the Femoral and Popliteal Arteries

n = 2); a true aneurysm of the popliteal artery (n= 4); an aneurysmal dilatation of a Biograft bypass (n= 2); a false aneurysm of the superficial femoral aneurysm (n= 1); and a false aneurysm of a composite bypass (n= 1). In 8 of the 10 patients the stent-graft was composed of one or more Palmaz stents sutured to an ePTFE tube graft; in the other 2 patients a venous covering was used in combination with Palmaz stents. The procedure was guided by angiography and intravascular ultrasound. The results of our investigation showed that endovascular stent-grafting of aneurysms of the femoropopliteal artery is a feasible but experimental technique that should be restricted to a selected group of patients.     

Axillofemoral Bypass Graft in a Spinal Cord Injured Patient with Impending Gangrene

ABSTRACT

The axillofemoral bypass graft, an extra-anatomic graft, connects the axillary artery to the femoral artery and is used in the treatment of significant aortoiliac occlusive disease in poor-risk patients. A common indication for axillofemoral bypass is a “hostile abdomen” (postoperative adhesions, neoplasms or radiation). Less frequent indications are aortic mycotic aneurysm, infected aortobifemoral bypass graft, aortoduodenal fistula, inflammatory aneurysm and extensive retroperitoneal fibrosis.

Spinal cord injured patients with peripheral arterial disease have two problems: 1) lack of premonitory symptoms (absence of claudication, paresthesias or rest pain) and 2) difficulty preventing pressure sores in the already poorly perfused limb. Indications for arterial reconstructive surgery are more drastic in this set of patients (impending gangrene and/or ischemic ulcers). Many spinal cord injured patients have sources of possible contamination (cystostomy and/or colostomy) which make intra-abdominal clean surgery impossible.

We present a spinal cord injured patient with a permanent cystostomy and impending gangrene of the left foot. He underwent a left axillofemoral bypass graft and had a good postoperative course.

We conclude that axillofemoral bypass graft is a good alternative for limb salvage in the spinal cord injured patient, especially when there is a source of possible contamination (colostomy and/or cystostomy) that would interfere with more common bypass grafting. The role of the noninvasive vascular laboratory for early detection of vascular disease is emphasized. (J Am Paraplegia Soc: 17; 171–176)     

Simultaneous surgery for left lung cancer and the aneurysm of an aberrant left subclavian artery in a patient with right aortic arch

A 69-year-old man with right aortic arch was diagnosed as having left lung cancer (cT2aN1M0, cStage IIA) and an aneurysm of an aberrant left subclavian artery. The aneurysm measured 36 mm in diameter and was located 1 cm peripheral from the origin in the area known as "Kommerell's diverticulu Left carotid artery-to-left subclavian artery bypass graft was placed through a left supraclavicular incision prior to thoracotomy. This bypass graft effectively prevented neurological and ischemic complications of the brain and left upper extremity while we safely and successfully performed resection of the aneurysm along with radical surgery for left lung cancer through left thoracotomy. There have been only 10 case reports, including the present case, that have described surgical resection of lung cancer in a patient with right aortic arch. In addition, this is the 1st report to describe simultaneous surgery for both left lung cancer and an aneurysm of an aberrant left subclavian artery in a patient with right aortic arch.

Abstract：

Objective Study the early and midterm results of a technique-total aortic arch replacement without using extracorporeal circulation or aortic bypass for the treatment of aortic aneurismal disease involving the transverse aortic arch and proximal descending aorta. Methods Between April and November 2004, 7 consecutive patients with true (n = 3) or false (n =4) aortic aneurysm underwent this procedure. The mean follow-up was 6. 6 years. The median age at operation was 57years ( range 23 to 75 years). Normothermia general anesthesia and median sternotomy combined with left anterior thoracotomy were administered. A partially occluding clamp was placed on ascending aorta and a longitude aortic incision was made. Anastomosis of a branched graft to ascending aorta in an end-to-side fashion was commenced. The descending aorta distal to the aneurysm was occluded and transected, and anastomosed to the distal end of the branched graft in an end-to-end fashion. Finally,the arch vessels were divided and anastomosed to the branches of the graft and the aneurysm excised. Results The average cross-clamp time of descending aorta, left common carotid artery, and innominate artery was (13.6 ±5.6)min, (5.7 ±0.8)min, and (7.8±2.5) min respectively. The mean intubation time was (12.3 ±4.1) hours. There were no adverse outcomes or neurologic complications in this series. All patients survived and recovered completely. The mean follow-up time was (79.7 ±2.1) months. All patients lead a normal life. There was no late death. CT follow-up study 6 years after surgery reveals no abnormal image. Conclusion Total aortic arch replacement without cardiopulmonary and aortic bypass is a feasible and effective method for the aortic aneurismal disease involving the transverse aortic arch and proximal descending aorta in selected patients.     

Open staged repair of splenic and extensive superior mesenteric artery aneurysms

A 31-year-old man with a history of multiple strokes of unknown etiology presented with multiple asymptomatic visceral artery aneurysms including a 3.3-cm bilobed splenic artery aneurysm and a 3.1-cm fusiform superior mesenteric artery aneurysm. He had no family history of aneurysms, and there was no evidence of collagen disease. He underwent open splenic artery aneurysm resection without splenectomy and had an uneventful recovery. Seven months later, he had open repair of his 14.6-cm-long fusiform superior mesenteric artery aneurysm with a 15-cm-long collagen-coated polyester interposition graft with multiple visceral branch reimplantations into the graft. The postoperative course was uneventful, and computed tomography confirmed patent graft and side branches. Two years later, the patient remained free of abdominal symptoms, although he suffered another episode of a mild stroke.
