Type B aortic dissection with rupture of the left common iliac artery: a case report 总被引:1,自引:0,他引:1
Type B aortic dissection involves the appearance of a false lumen distal to the left subclavian artery and extending distally into the descending thoracic aorta and into the abdominal aorta. Complications of the dissection include rupture of the thoracic aorta, leg ischemia, visceral ischemia, and renal failure. A 37-year-old man presented with complaints of sudden onset of chest pain, left leg pain, and numbness. Examination revealed no femoral, popliteal, or distal pulses with decreased sensory and motor function on the left lower extremity. A CT scan revealed an aortic dissection at the proximal descending aorta extending into the iliac arteries with a left retroperitoneal hematoma at the iliac bifurcation. An MRI confirmed the dissection distal to the left subclavian artery into the iliac artery with a distal occlusion. Exploration revealed rupture of the left iliac artery dissection with arterial occlusion and a contained hematoma. The common iliac artery was ligated and an 8-mm Dacron bypass graft from the right common femoral artery to the left femoral artery was performed. Type B aortic dissection can present as rupture of the common iliac artery. Revascularization of the extremity with a femoral-femoral crossover graft is the recommended procedure in the absence of visceral ischemia. The surgeon should have a keen suspicion of this rare complication and its management. 相似文献

We present two cases with an occluded left subclavian artery requiring coronary artery bypass grafting. A preoperative angiogram confirmed that the subclavian artery, including the internal thoracic artery distal from the occlusion, was thoroughly intact, in both cases. Immediately after reconstructing the subclavian artery using an aortoaxillary bypass with an 8 mm ring-reinforced polytetrafluoroethylene graft, each patient underwent double coronary artery bypass grafting using the affected left internal thoracic artery with either the right internal thoracic artery or a saphenous vein in the same anesthetic setting. Symptomatic relief was excellent. In both cases, a postoperative angiographic study showed good function of the left internal thoracic artery graft supplying blood to the coronary artery through the aortoaxillary bypass graft. 相似文献

Our patient had 80% stenosis of the brachiocephalic artery and total occlusion of the left carotid and left subclavian arteries. Ascending aorta to brachiocephalic artery bypass grafting was performed, with a 10 mm Dacron graft. The right axillary artery was cannulated, and during construction of the distal anastomosis cerebral blood flow was from the right axillary artery. We believe this technique may be beneficial in surgery on an artery in which cerebral blood flow depends exclusively. 相似文献

A 47-year-old woman presented with two transient ischemic attacks due to occlusion of the left internal carotid artery. The affected artery was revascularized by vasa vasorum. Angiography showed occlusion of the left common carotid artery including the origin of the internal carotid artery. The distal internal carotid artery was revascularized by vasa vasorum at the level of the second cervical vertebral body. Left subclavian artery-internal carotid artery bypass surgery using a saphenous vein graft was performed successfully, during which the narrowed but patent lumen of the internal carotid artery was confirmed. Follow-up angiography showed enlargement of the left internal carotid artery distal to the patent bypass. Reconstructive bypass surgery is a possible treatment for patients with occluded internal carotid artery revascularized by vasa vasorum. Angiographic detection of the lumen of the internal carotid artery is important for surgical consideration. 相似文献

In-situ internal mammary artery (IMA) grafts have a better patency rate than free IMA grafts. Every effort is made to leave the IMA as an in-situ graft attached to the subclavian artery. A 56-year-old patient underwent reoperation because of occlusion of the vein graft to the left anterior descending coronary artery (LAD). At the second operation, the left IMA was anastomosed to the segment of the LAD distal to the first anastomotic site. The hyperinflated lung crossed the midline and stretched the IMA graft. The herniated portion of the left lung which stretched the IMA graft was resected with a 9-cm long linear stapler along the course of the IMA graft. No harmful effects were observed. This is a simple and safe method to reduce the tension on the IMA graft due to the hyperinflated lung. 相似文献

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. 相似文献

A patient had an occlusion of the left subclavian artery just proximal to the takeoff of a previously placed subclavian-carotid graft. This caused reversal of flow in the graft and a symptomatic steal of blood via to the intracranial arteries. An axilloaxillary graft restored forward flow. In a second patient, a steal occurred from the right carotid and vertebral systems into the distal carotid system of the left side that has been isolated by a proximal carotide artery occlusion from arteriosclerosis. A saphenous vein, used as a bypass from the subclavian to the carotid artery, restored normal flow. Thus, the carotide system may be the low-pressure area responsible for the steal, although this is rarer than the subclavian. 相似文献

Although thrombogenicity of the prosthetic graft, progression of the atherosclerotic disease and distal anastomotic intimal hyperplasia are known etiologic factors of late graft failure, its occurrence is frequently encountered in the late graft occlusion. Forth-two canine PTFE iliofemoral grafts (all with end-to-side distal anastomosis) were studied. Computer digitization revealed that distal anastomotic intimal hyperplasia occurred exclusively at the heel and the toe of the graft and the floor of the host artery. The distal anastomotic intimal hyperplasia was 80-130 cells thick. Light microscopy and transmission electron microscopy revealed a similar architecture of interlamination of cellular elements and extracellular matrix in the hyperplastic cells. Transmission electron microscopy further defined a gradual cell transformation and orientation from the graft to the lumen. The cells near the graft were characterized by a gradual reduction of rough endoplasmic reticulum with a concomitant acquisition of myofilaments, transforming ovoid mesenchymoid cells to slender myofibroblasts. The orientation of cells in distal anastomotic intimal hyperplasia was embodied by random cell distribution at the periphery to a well-organized interlamination of myofibroblasts and extracellular matrix near the lumen. Distal anastomotic intimal hyperplasia is a biologic entity with active cellular and subcellular events. Its biogenesis appears to be influenced by the hemodynamics of blood flow at the distal anastomosis. 相似文献

A 62-year-old man with end-stage ischemic cardiomyopathy and left ventricular function of 20% was evaluated for heart transplantation. Cardiac catheterization revealed proximal occlusion of the dominant right coronary artery (RCA) with collateral blood flow and significant stenosis in the distal part, but no significant re-occlusions of the stented left coronary artery and no significant stenosis of the left circumflex artery. When the patient became catecholamine dependent, Novacor left ventricular assist device (LVAD) implantation, as a bridge to transplantation, was considered and the patient operated upon. To avoid ischemic right heart failure after LVAD implantation, a concomitant re-vascularization of the distal RCA was performed. The post-operative course was uneventful. Five weeks later, a control angiogram showed the patent bypass graft. The distal stenosis of the RCA was treated successfully with dilation and stent implantation. The patient is presently in stable condition on LVAD and awaits transplantation as an outpatient. 相似文献

A 59-year-old man with 18-year history of renal dialysis due to chronic nephritis suffered coronary artery disease, which
was complete occlusion of the right coronary artery and diffuse 90% stenosis of the proximal left anterior descending artery.
Off-pump coronary artery bypass grafting was performed. Saphenous vein (SV) was anastomosed with left internal thoracic artery
(ITA) as a T-graft. Left ITA was anastomosed to the left anterior descending artery. The end of SV was sewn on the posterior
descending artery. Coronary and graft angiography performed 2 weeks after the operation showed good patency with good distal
run-off of both left ITA and SV. Three months after the operation, he was admitted with unstable angina. Angiography revealed
accelerated SV graft stenosis without any change of prior coronary disease. However, angiography 7 months after the operation
revealed complete obstruction of the S V graft when he was admitted because of recurrent anginal pain. 相似文献

The shriveled, stenotic mammary graft sometimes observed after internal mammary artery (IMA) to coronary artery bypass grafting has been attributed to competitive flow from the insufficiently stenosed native coronary vessel. To study further the effects of native coronary artery competing flow on IMA graft flow, 10 dogs (mean weight, 23.5 +/- 3.69 kg) underwent coronary artery bypass grafting using the pedicled left IMA anastomosed to a normal, fully patent proximal circumflex (CFX) coronary artery. The procedure was performed through a left thoracotomy, off pump, using a brief local occlusion to perform the anastomosis. Native in situ IMA flow, CFX flow distal to the anastomosis, and IMA graft flow were measured using calibrated electromagnetic flow probes. When the CFX proximal to the anastomosis was occluded transiently, IMA flow increased to supply 100% of the previously measured distal CFX flow (60.2 +/- 7.9 mL/min). When both the IMA graft and CFX proximal to the anastomosis were patent, total distal perfusion was maintained (58.9 +/- 7.8 mL/min) and relative IMA graft flow (26.5 +/- 3.3 mL/min) was proportional to the relative diameter of the IMA graft to the native coronary artery (r = 0.96). The mean flow in the IMA in situ on the chest wall before its division was 23.8 +/- 8.1 mL/min. These results suggest that, at least acutely in a canine model, IMA graft flow is maintained above in situ levels even when grafted to a completely patent coronary artery and that acute competitive flow probably does not cause mammary artery shriveling. 相似文献

Is distal anastomosis only to the true channel in chronic type B aortic dissection justified? 总被引:1,自引:0,他引:1

BACKGROUND: We investigated long-term outcomes of the distal false lumen of the aorta and aortic branches after distal anastomosis of the graft only to the true lumen in chronic type B aortic dissection. METHODS: From November 1979 until June 1998, we treated 98 patients without Marfan syndrome who had chronic type B aortic dissection and underwent replacement of the descending aorta, 79 of whom had distal anastomosis to the true lumen only. The celiac artery originated from the false lumen in 11 patients, superior mesenteric artery in 5, right renal artery in 19, and left renal artery in 16. RESULTS: There were 12 (15.1%) early deaths. Spinal cord ischemia was detected in 5 patients. Postoperative follow-up was achieved in 67 patients, and 13 patients died. Postoperative survival at 10 years was 67.6% +/- 7.1%. Eight patients had complete occlusion of the distal false lumen, 54 patients had occlusion of the false lumen down to the celiac artery, and 5 patients had a patent false lumen. Four patients required further replacement of the thoracoabdominal aorta. CONCLUSIONS: In non-Marfan patients with chronic type B aortic dissection, the false lumen distal to the graft anastomosis was likely to be thrombosed when the graft was anastomosed to the true lumen only. Postoperative visceral circulation was not compromised, but spinal cord ischemia is a problem that remains to be solved. 相似文献

A 71-year-old man was operated for a complete occlusion of the left common iliac artery caused by arteriosclerosis obliterans. Cross-over bypass was performed from the right external iliac artery to the left superficial femoral artery in June 1978, using a Double Velour Dacron graft (Cooley) 8 mm in diameter. In February 1985, the patient noticed the pulsatile mass in his left groin. Angiography showed a false aneurysm at the distal anastomosis of the graft. On operation, 2 aneurysmal dilatations were found on the distal anastomosis. After resection of the aneurysms, the reconstruction was established by EPTFE graft successfully. The resected specimen showed that one of the aneurysms was caused by the anastomotic failure of the distal portion of the graft, but that the other was the false aneurysm caused by rupture of the implanted graft. Two ruptured holes were confirmed to be 20 X 25 mm, 10 X 15 mm in size respectively, 10 mm proximal to the anastomotic aneurysm. Rupture of the Dacron arterial prosthesis is a rare complication. Only 23 cases have been reported in the United States. But some literatures show that the incidence of the failure of the Dacron prosthesis was about 3%. Therefore, we should make a long-term follow-up to the patients implanted Dacron arterial prostheses. 相似文献

We report a rare case of a ruptured internal carotid-posterior communicating artery (IC-PcomA) aneurysm associated with an anomalous hyperplastic anterior choroidal artery (AchoA) and aneuysm. A 64-year-old woman was admitted to our hospital because of a sudden onset of headache. CT scan showed subarachnoid hemorrhage. Left internal carotid angiograms showed a saccular aneurysm at the IC-PcomA region. Left posterior cerebral artery filling from the fetal type PcomA and an anomalous hyperplastic AchoA originating from the internal carotid artery (ICA) were also revealed. Left vertebral angiograms (Allcock test) revealed the left ICA and an anomalous hyperplastic AchoA via the fetal type PcomA. The patient was surgically treated through the left pterional transsylvian approach. The ruptured aneurysm was observed at the IC-PcomA region. The unruptured small aneurysm was found on just distal to the ruptured aneurysm. The PcomA and an anomalous hyperplastic AchoA were not observed behind the ICA. To prevent bleeding, the ruptured aneurysm and unruptured small aneurysm were clipped. Postoperative left internal carotid angiograms demonstrated no aneurysm was observed at the IC-PcomA region. The patency of the fetal type PcomA and an anomalous hyperplastic AchoA were preserved. The 7 reported cases of a intracranial aneurysm associated with an anomalous hyperplastic AchoA with our case are reviewed and their neuroradiological and clinical features are discussed. 相似文献

Surgery for chronic total occlusion of the left main coronary artery--myocardial preservation 总被引:1,自引:0,他引:1
Ipek G Omeroglu SN Ardal H Mansuroglu D Kayalar N Sismanoglu M Guler M Daglar B Yakut C 《Journal of cardiac surgery》2005,20(1):60-64
We report seven patients with chronic total occlusion of the left main coronary artery that were operated in our institution and discuss the myocardial preservation options in these patients. In addition to total occlusion of the left main coronary artery, three patients also had severe lesions of right coronary artery. Prior myocardial infarction history and significantly depressed left ventricle functions were detected in all three patients with right coronary artery lesions. Five patients were operated on cardiopulmonary bypass while two patients were operated off pump. All patients received alternating antegrade/retrograde cardioplegia for myocardial preservation. In patients with simultaneous right coronary artery disease we first established the origin of the collaterals to the left coronary system. For patients with collaterals arising from the right coronary artery segment distal to the right coronary artery lesion, the antegrade component was administered through the saphenous vein graft bypassed to a distal part of right coronary artery segment. Thus we have achieved a more effective distribution of the antegrade cardioplegia. In off-pump-operated patients the left coronary system was revascularized before the right coronary system. Postoperative low cardiac output syndrome occurred in only one patient who was operated off pump. There was no operative and early mortality. Mean follow-up was 32 +/- 21.42 (range, 4 to 60) months. Alternating antegrade/retrograde cardioplegia was used with acceptable results in patients with total occlusion of the left main coronary artery. In patients with simultaneous RCA lesion we recommend regulation of the antegrade component based on the origin of collaterals that supplies the left coronary system. In off-pump-operated patients we suggest avoiding of clamping of right coronary artery at the beginning of the operation while it still supplies all the coronary circulation. 相似文献

Occlusion of the aortofemoral prosthetic graft 总被引:1,自引:0,他引:1
A R Downs 《Canadian journal of surgery》1986,29(5):342-344
The commonest late complication of aortofemoral prosthetic grafting is graft-limb occlusion, the usual cause of which is outflow obstruction due to anastomotic neointimal hyperplasia or progressive atherosclerosis in the deep femoral artery. Occasionally graft-limb occlusion is due to thrombosis of an anastomotic false aneurysm or is associated with graft infection. Inflow occlusion at the aortic anastomosis is uncommon unless the aortic anastomosis is at the lower end of the aorta distal to the inferior mesenteric artery. When graft-limb occlusion occurs, severe ischemia usually necessitates urgent revascularization to save the leg. Graft thrombectomy and profundaplasty may be successful; however, a cross-femoral graft to the distal patent deep femoral artery is probably the simplest procedure and is usually effective. Occasionally a distal femoropopliteal reconstruction is necessary to establish a satisfactory outflow. Unsuccessful reconstruction of a graft-limb occlusion usually necessitates a high, above-knee amputation. 相似文献

OBJECTIVE: Total arterial myocardial revascularization may be achieved by using the 'Y-graft' techniques with different free arterial conduits anastomosed off the side of an in situ internal thoracic artery to reach distal coronary segments. This study was assessed to measure intraoperative graft flow, resistance and clinical outcomes. METHODS: Seventy-six patients who underwent coronary artery bypass grafting during a time period of 27 months were enrolled in this prospective study. All patients received sequential grafting by using both internal thoracic arteries, inferior epigastric and right gastroepiploic artery joined as a composite Y graft. Intraoperative graft flow, resistance and derived variables were measured. RESULTS: All patients except one showed good flow (ml/min and waveform) in either branch of composite graft. In one case, a low-flow situation through the graft was registered requiring surgical correction. Temporary occlusion of either branch did not significantly affect flow in the other side of the arterial Y. Mid-term follow-up (3 and 15 months) and angiographic studies showed a high graft patency rate. CONCLUSION: Composite arterial grafts provide excellent early and mid-term clinical results. Flow reserve of the left internal thoracic artery did not affect blood flow and resistance on either branch of the Y graft when temporary occlusion on the other side of the arterial Y was performed. 相似文献

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. 相似文献

BACKGROUND: The initial use of radial artery (RA) for myocardial revascularization was abandoned due to high incidence of early occlusion. The revival of radial artery graft use was attributable to the improved harvesting techniques as well as the introduction of antispasm prophylaxis by calcium channel blockers. Various techniques of harvesting RA have been described and extrafascial harvest is one of the techniques to minimize trauma during harvest. The immediate arm complications and mid-term angiographic patency of the radial artery grafts harvested using extrafascial no-touch technique and used as a conduit for myocardial revascularization were not documented well in the literature. METHODS: Between January 1997 and February 2003, 385 patients were operated for coronary artery bypass grafting using radial artery graft as one of the conduits. We used extrafascial no-touch technique and a coagulation current cautery at a strength of 10 to 15 W to control the bleeding during the blunt dissection of the radial artery. The complications related to the radial artery harvest were prospectively recorded and analyzed. This conduit was used as a free graft in 272 patients, left internal mammary artery and radial artery Y graft in 61 patients, Right internal mammary artery, and radial artery composite in situ graft in 52 patients. The radial artery donor arm in these patients was evaluated for complications. Angiographic evaluation of the radial artery graft was carried out randomly in 51 patients and angiography was done after an interval of 6 to 72 months (mean 29.55 +/- 21.77 months). RESULTS: In two patients, although the preoperative Allen test was negative, the radial artery was not harvested after completion of the dissection and was left in situ because the pulse could not be felt in the radial artery distal to the clamp after trial occlusion of the mid part of RA. The arm complications noticed were cutaneous parasthesias in 9 patients (2.33%), which subsided in 4 weeks, stitch abscess and superficial wound infection in 4 patients (1.03%), hematoma/seroma treated with drainage in outpatient department in 3 patients (0.78%), and wound infection requiring open drainage in an operating room in one patient (0.76%). Angiographically radial artery was patent in 48 of 51 patients (94.11%). CONCLUSIONS: The extrafascial technique of radial artery harvest is safe and an easily reproducible method with minimal arm complications and good mid-term clinical and angiographic results. The mid-term angiographic patency rates of RA harvested using this technique are comparable to that of the published results of intrafascially harvested radial artery grafts and left internal mammary artery grafts. 相似文献
