The internal resistance of a material to moving some parts of it parallel to a fixed plane, in contrast to stretching (TENSILE STRENGTH) or compression (COMPRESSIVE STRENGTH). Ionic crystals are brittle because, when subjected to shear, ions of the same charge are brought next to each other, which causes repulsion.
Surgery performed on the heart.
A pathological condition caused by impaired blood flow in the basal regions of cerebral hemispheres (BASAL GANGLIA), such as INFARCTION; HEMORRHAGE; or ISCHEMIA in vessels of this brain region including the lateral lenticulostriate arteries. Primary clinical manifestations include involuntary movements (DYSKINESIAS) and muscle weakness (HEMIPARESIS).
The failure by the observer to measure or identify a phenomenon accurately, which results in an error. Sources for this may be due to the observer's missing an abnormality, or to faulty technique resulting in incorrect test measurement, or to misinterpretation of the data. Two varieties are inter-observer variation (the amount observers vary from one another when reporting on the same material) and intra-observer variation (the amount one observer varies between observations when reporting more than once on the same material).

The value of late computed tomographic scanning in identification of vascular abnormalities after abdominal aortic aneurysm repair. (1/810)

PURPOSE: The purpose of this study was to determine the prevalence of late arterial abnormalities after aortic aneurysm repair and thus to suggest a routine for postoperative radiologic follow-up examination and to establish reference criteria for endovascular repair. METHODS: Computed tomographic (CT) scan follow-up examination was obtained at 8 to 9 years after abdominal aortic aneurysm (AAA) repair on a cohort of patients enrolled in the Canadian Aneurysm Study. The original registry consisted of 680 patients who underwent repair of nonruptured AAA. When the request for CT scan follow-up examination was sent in 1994, 251 patients were alive and potentially available for CT scan follow-up examination and 94 patients agreed to undergo abdominal and thoracic CT scanning procedures. Each scan was interpreted independently by two vascular radiologists. RESULTS: For analysis, the aorta was divided into five defined segments and an aneurysm was defined as a more than 50% enlargement from the expected normal value as defined in the reporting standards for aneurysms. With this strict definition, 64.9% of patients had aneurysmal dilatation and the abnormality was considered as a possible indication for surgical repair in 13.8%. Of the 39 patients who underwent initial repair with a tube graft, 12 (30.8%) were found to have an iliac aneurysm and six of these aneurysms (15.4%) were of possible surgical significance. Graft dilatation was observed from the time of operation (median graft size of 18 mm) to a median size of 22 mm as measured by means of CT scanning at follow-up examination. Fluid or thrombus was seen around the graft in 28% of the cases, and bowel was believed to be intimately associated with the graft in 7%. CONCLUSION: Late follow-up CT scans after AAA repair often show vascular abnormalities. Most of these abnormalities are not clinically significant, but, in 13.8% of patients, the thoracic or abdominal aortic segment was aneurysmal and, in 15.4% of patients who underwent tube graft placement, one of the iliac arteries was significantly abnormal to warrant consideration for surgical repair. On the basis of these findings, a routine CT follow-up examination after 5 years is recommended. This study provides a population-based study for comparison with the results of endovascular repair.  (+info)

Video-assisted crossover iliofemoral obturator bypass grafting: a minimally invasive approach to extra-anatomic lower limb revascularization. (2/810)

Graft infection continues to be one of the most feared complications in vascular surgery. It can lead to disruption of anastomoses with life-threatening bleeding, thrombosis of the bypass graft, and systemic septic manifestations. One method to ensure adequate limb perfusion after removal of an infected aortofemoral graft is extra-anatomical bypass grafting. We used a minimally invasive, video-assisted approach to implant a crossover iliofemoral obturator bypass graft in a patient with infection of the left limb of an aortofemoral bifurcated graft. This appears to be the first case report describing the use of this technique.  (+info)

Three ventriculoplasty techniques applied to three left-ventricular pseudoaneurysms in the same patient. (3/810)

A 59-year-old male patient underwent surgery for triple-vessel coronary artery disease and left-ventricular aneurysm in 1994. Four months after coronary artery bypass grafting and classical left-ventricular aneurysmectomy (with Teflon felt strips), a left-ventricular pseudoaneurysm developed due to infection, and this was treated surgically with an autologous glutaraldehyde-treated pericardium patch over which an omental pedicle graft was placed. Two months later, under emergent conditions, re-repair was performed with a diaphragmatic pericardial pedicle graft due to pseudoaneurysm reformation and rupture. A 3rd repair was required in a 3rd episode 8 months later. Sternocostal resection enabled implantation of the left pectoralis major muscle into the ventricular defect. Six months after the last surgical intervention, the patient died of cerebral malignancy. Pseudoaneurysm reformation, however, had not been observed. To our knowledge, our case is the 1st reported in the literature in which there have been 3 or more different operative techniques applied to 3 or more distinct episodes of pseudoaneurysm formation secondary to post-aneurysmectomy infection. We propose that pectoral muscle flaps be strongly considered as a material for re-repair of left-ventricular aneurysms.  (+info)

Pseudoaneurysm of the vertebral artery. (4/810)

Pseudoaneurysms of the vertebral artery are rare. Their treatment depends on the location, size, cause, and coexisting injuries.

Feasibility of three-dimensional intravascular ultrasonography: preliminary clinical studies. (5/810)

The aim of this study was to demonstrate the clinical utility of reconstructed three-dimensional intravascular ultrasonography using a voxel-based volume rendering technique. Three-dimensional reconstruction of intravascular ultrasonographic data was performed in 12 patients with various vascular abnormalities during interventional radiology procedures. A stepping motor device was used to pull either a 12.5 or a 20 MHz catheter-based transducer through the lumen of a variety of vessels at a rate of 1.5 mm/s. Images were downloaded to a Life Imaging System for three-dimensional reconstruction. The value of three-dimensional ultrasonographic imaging was evaluated in comparison to conventional intravascular ultrasonography. A variety of abnormalities were demonstrated in reconstructed three-dimensional ultrasound imaging, including arterial atheroma and plaque, aneurysm and pseudoaneurysm, aortic dissection and stenosis (May-Thurner syndrome). The vascular branches and accessory vessels, as well as their relationships to each other, were easily demonstrated on three-dimensional imaging by selecting an appropriate angle, plane, and section of the image. The dimensions and shapes of the vascular lumen were determined in the longitudinal view. Three-dimensional information proved useful for determining the distribution and type of plaque in vessels. Reconstructed three-dimensional imaging allows for global evaluation of the dissection entry site, extent of the flap, and the false lumen of a pseudoaneurysm. Intravascular three-dimensional ultrasonography provides information complementary to that obtained with two-dimensional imaging. It supplies information about spatial relationships of anatomic structures that cannot be evaluated using conventional imaging methods.  (+info)

True and anastomotic femoral artery aneurysms: is the risk of rupture and thrombosis related to the size of the aneurysms? (6/810)

OBJECTIVE: the management of asymptomatic femoral aneurysms remains controversial. The purpose of this study was to investigate the relation between the diameter of true and anastomotic aneurysms and the risk of rupture. DESIGN: retrospective study. MATERIAL AND METHODS: we reviewed the case records of 17 patients who underwent 17 arterial reconstructive procedures for true femoral aneurysms. In addition, the case records of 76 patients who underwent 90 arterial reconstructive procedures for femoral anastomotic aneurysms were identified and reviewed. RESULTS: the rupture rate for aneurysms less than 5 cm in diameter was 1.6% (one out of 64) compared with 16% (seven out of 43) for those larger than 5 cm. The thrombosis rate for aneurysms less than 5 cm in diameter was 17% compared with 5% for those larger than 5 cm. CONCLUSIONS: this study seems to show that the risk of rupture of femoral artery aneurysms is related to the diameter of the aneurysms. However, the rise in the risk of rupture with increasing size seems less dramatic than for abdominal aortic aneurysm (AAA).  (+info)

Pseudoaneurysm of the subclavian artery due to Xanthomonas pneumonia in a patient with acute myeloid leukemia: its rupture treated by transcatheter coil embolization. (8/810)

A 52-year-old male with acute myeloid leukemia developed pseudoaneurysm of the subclavian artery. Pneumonia due to Xanthomonas maltophilia, which was multi-drug resistant, progressed to a lung abscess even under administration of antibiotics. This lung infection contiguous to the left carotid and subclavian arteries was suggested to have caused the pseudoaneurysm of the subclavian artery. The rupture of the aneurysm by penetration to the trachea amounted to about 1,000 ml of bleeding; fortunately the bleeding ceased spontaneously. Nonetheless, an emergency transcatheter coil embolization prevented re-bleeding. Endovascular treatment should be considered especially for aneurysms which develop in patients with underlying diseases.  (+info)

Ultrasound guided percutaneous thrombin injection has recently been described for the treatment of iatrogenic femoral pseudoaneurysms. Patient selection and technical aspects of this technique are still evolving and safety data, particularly after coronary intervention, remains limited. The percutaneous thrombin injection of femoral artery pseudoaneurysms in 13 consecutive patients, most of whom were receiving antiplatelet/anticoagulant treatment (aspirin 11, heparin 4, clopidogrel 6), is reported. Thrombin (1000 U/ml) was injected over several seconds until Doppler colour flow within the cavity ceased. The median dose of thrombin injected was 800 U (range 200-1000 U) and the treatment was successful in all cases without complication. In one case, thrombus was visualised within the arterial lumen immediately after thrombin injection, but this dissolved spontaneously within five minutes without evidence of embolisation. In contrast to ultrasound guided compression, percutaneous thrombin injection ...

Anastomotic pseudoaneurysm is a rare complication following aorta replacement. However, this condition is life-threatening because of the high risk of rupture. This complication has a mortality rate of 61% if no intervention is performed.[1] Its foremost cause may be the high local tension or the edematous aortic wall, which causes sutures to lacerate the aortic wall. Another possible cause is the graft infection.[2]. The incidence rate of anastomotic pseudoaneurysm ranges from 0.5% to 15%.[3] To date, two interventions are mainly used to manage this condition: The surgical repair and thoracic endovascular aortic repair. Surgical treatment involves the replacement of a prosthetic graft or direct repair via a redo left lateral thoracotomy. Such redo thoracotomy is extremely difficult because of the adhesion of lungs to the chest wall in the left chest cavity. The high risk of lung injury was reported for more than 30% of the patients.[4] Meanwhile, open surgery has a high mortality ...

Case Reports: Three patients (2 women and 1 man aged 52, 68, and 43 years, respectively) developed pseudoaneurysm of the ascending aorta following thoracic organ transplantation. Due to the prohibitive risk of open surgery in each case, an endovascular repair of the ascending aorta was performed, with implantation of 1 to 3 stent-grafts to span the lesions. Follow-up imaging demonstrated complete exclusion of the pseudoaneurysms, with excellent outcomes at 4 months, 6 months, and 3 years. Conclusion: Stent-grafting of the ascending aorta represents a viable approach to pseudoaneurysm in the post-transplant setting.. AB - Purpose: To demonstrate ...

Relatively straightforward placement of an umbilical arterial catheter can be complicated by psuedoaneurysm formation in the presence of a coagulopathy.

Pertinent imaging findings are described with a brief literature review.. ...
Pseudoaneurysms, or false aneurysms, are differentiated from true aneurysms by the layers of the artery involved. Pseudoaneurysms are the result of the rupture of all three layers of the artery: the tunica intima, media, and adventitia. The aneurysm is contained by an organized hematoma or neighboring connective tissue. With true aneurysms, the outermost layer, the adventitia, remains intact.. As a result of its secure location, injury to the basilar artery is rare.1 Only 10% of traumatic aneurysms in the brain occur in the posterior circulation. As was seen in this case, the majority of basilar artery aneurysms are associated with skull base fractures. In addition, the connective tissue surrounding the basilar artery is usually unable to contain the aneurysm, making it improbable that a patient would survive a traumatic aneurysm in the posterior circulation.2 Rapid treatment is imperative because of the high morbidity and mortality associated with basilar artery pseudoaneurysms. ...
A sixty-six years old male patient presented with left upper thigh pulsatile swelling for 5 months. He had no history of any trauma or chronic infection. All necessary investigations were done. The diagnosis was uncertain and could not differentiate between femoral artery pseudo- aneurysm and vascular soft tissue tumor. Intraoperative findings were suggested chronic pseudo-aneurysm of the femoral artery and diagnosis supported by histopathology. We concluded that chronic non-traumatic femoral artery pseudo-aneurysm is very rare and early surgery should be initiated to prevent complications..

Pseudoaneurysm of the ascending aorta is a rare but potentially lethal complication arising after interventions involving surgical manipulation of the aorta. The classic therapeutic management strategy consists of high-risk surgical reintervention. In recent years, percutaneous treatment has emerged as an alternative to surgery. Here, we present a case of successful repair of an aortic pseudoaneurysm by percutaneous intervention.. An 81-year-old woman presented with persistent chest pain 3 weeks after surgical replacement of the aortic valve. Thoracic computed tomography revealed a pseudoaneurysm of the ascending aorta measuring 40×27 mm, with a narrow neck connected to the anterior face of the aorta (Ao) above the level of the pulmonary artery (PA) and the left main coronary artery (LMCA) (Figures 1A and B). The case was discussed in a medical-surgical session, and a decision was made to perform percutaneous closure of the pseudoaneurysm. An aortogram showed a rounded cavity connected to the ...
In addition to haematoma and arteriovenous fistula, the iatrogenic pseudoaneurysm is a common complication of vascular access that is caused by a perforation in the arterial wall. Iatrogenic pseudoaneurysms can progress in size and lead to rupture and active bleeding. Over the previous few decades, therapeutic methods have evolved from surgical repair to less invasive options, such as ultrasound-guided compression therapy (UGCT) and ultrasound-guided thrombin injection (UGTI). This paper presents an overview of the diagnostic and treatment modalities used in femoral pseudoaneurysms as well as a comprehensive summary of previous studies that analysed the success and complication rates of UGCT and UGTI ...

Another option for treatment is ultrasound probe compression of the neck of the pseudoaneurysm. The neck of the pseudoaneurysm is the narrow path of blood flow between the artery, through the arterial wall, and into the pseudoaneurysm cavity. The artery, neck, and pseudoaneurysm are seen on ultrasound. The ultrasound probe can be pushed firmly against the patients skin to compress the neck of the pseudoaneurysm for usually about 20 minutes. During this time, the blood within the pseudoaneurysm clots; after the probe is then removed, the pseudoaneurysm will hopefully remain clotted and will not continue to expand. The procedure may be stopped early due to patient discomfort. It is less successful if the patient is obese, since there is more fatty tissue between the skin and the neck of the pseudoaneurysm. It also is less successful if the neck of the pseudoaneurysm is wider, since it is less likely to clot off during the period of compression. Finally, it is also much less successful if the ...
Ruptured pseudoaneurysm following pelvic surgery is a rare and fatal complication. Because of its rarity, existing evidence is limited to a small case series. A 60-year-old woman underwent staging laparotomy, including pelvic and para-aortic lymphadenectomy, for ovarian cancer. On the 11th day, the patient developed a sudden lumbar pain and loss of consciousness, which resulted in a state of shock. She was diagnosed as having a pelvic abscess and ruptured external iliac artery pseudoaneurysm. We performed ligation of the external iliac artery to restrain hemorrhage and femoro-femoral artery bypass to prevent infection, which saved the patients life ...
A 61-year-old man with acute myocardial infarction developed a painful hematoma in his groin after percutaneous coronary intervention. Ultrasonography, including color Doppler, detected a pulsatile, hypoechogenic, single compartment lesion (2.3 × 3.0 × 2.9 cm) consistent with a partially thrombosed pseudoaneurysm originating from the distal part of the common femoral artery (Figure, A). Sampling from the neck of the pseudoaneurysm connecting the pseudoaneurysm to the common femoral artery, spectral Doppler waveform analysis unexpectedly displayed flow directed toward the pseudoaneurysm cavity both in systole and diastole (Figure, B), in contrast to the characteristic to and fro-like flow pattern detected in uncomplicated pseudoaneurysms (Figure, C). The turbulent monophasic flow of the pseudoaneurysm neck, with its characteristic high end-diastolic velocities (Figure, B), suggested flow to an area of low peripheral resistance, in contrast to the normal high-resistance biphasic arterial flow ...
A 65-year-old alcoholic man presented with subacute exertional dyspnea and left shoulder pain. Three years earlier he was bitten by a rat while feeding a pet snake, resulting in sepsis, which was treated with intravenous antibiotics. Cardiac catheterization at an outside hospital was interpreted as myocardial bridging of the circumflex artery, and transthoracic 2-dimensional echocardiogram raised suspicion of aortic dissection, resulting in a transfer to our hospital.. Chest radiograph at admission was unremarkable, but ECG revealed sinus tachycardia with inferolateral ST-T wave changes, suggestive of ischemia (Figure 1A and 1B). Bedside transesophageal echocardiogram with 3-dimensional full-volume reconstruction showed severe aortic stenosis and a large pseudoaneurysm (PSA) of the mitral-aortic intervalvular fibrosa, with a mobile calcification noted at the opening of the PSA cavity (Figure 2A and 2B and online-only Data Supplement Movie I). Cardiac computed tomographic angiography established ...

Pseudoaneurysms are a recognised complication of pancreatitis. Necrotising vasculitis with resultant aneurysmal changes in peri-pancreatic vessels is more recognised in chronic pancreatitis. Similar pseudoaneurysms have been described in association with acute pancreatitis, but only occur in approximately 10% of cases. The damage in pancreatitis is caused by released and activated pancreatic enzymes. Necrotizing vasculitis and erosion of vessel walls results in aneurysmal changes in peripancreatic vessels. The vessels of the coeliac trunk are the most commonly affected. Haemorrhage from arterial pseudoaneurysm rupture is potentially fatal. In most cases, massive gastrointestinal bleeding is typical at onset and prognosis of these cases is usually poor. Early diagnosis and treatment of this complication is therefore important. It is well recognised and documented that radiology has a major role in diagnosis and management. Ultrasound may be useful in diagnosing pseudoaneurysm complicating acute ...
A pseudoaneurysm, also known as a false aneurysm, is a collection of blood that forms between the two outer layers of an artery, the muscularis propria and the adventitia. It is usually caused by a penetrating injury to the vessel, which then bleeds, but forms a space between the above two layers, rather than exiting the vessel. It may be pulsatile and can resemble a true aneurysm. A true aneurysm involves all three layers of the blood vessel. A dissecting aneurysm is when blood from the vessel lumen tracks between the two inner layers, the intima and the muscularis. This can cause blockage of the flow. A perivascular hematoma is a collection of blood that is external to the three vessel layers. Due to being close to the vessel, it can also be pulsatile, and can be mistaken for a pseudoaneurysm or aneurysm. Femoral pseudoaneurysms may complicate up to 8% of vascular interventional procedures. Small pseudoaneurysms can spontaneously clot, while others need definitive treatment. A pseudoaneurysm ...
Pseudoaneurysm formation after vascular reconstruction is a rarely encountered problem in the treatment of peripheral arterial disease. It has most commonly been described in the vascular surgical literature as a delayed complication of lower extremity bypass surgery, and the usual mode of repair has been surgical. Recent advances in minimally invasive therapy for this clinical entity have centered on ultrasound-guided compression and thrombin injection to obliterate the cavity and restore vascular integrity. With the advent of stent-supported angioplasty, endovascular methods of treatment for

The risk of rupture for pseudoaneurysm in transplanted patients is 50% [3]; if untreated the reported mortality-rate is 69% or higher in case of extrahepatic pseudoaneurysm [4]. Altough pseudoaneurysms are uncommon, they represent potential life-threatening post-OLT arterial complications which must be promptly diagnosed and treated. In fact, without an early treatment, they may threaten patient and graft survival, limiting the long-term success of transplantation ...
The principal surgical approach is the median sternotomy and consequently the exclusion of SLVP by direct suture or patch positioning. According to O Flynn et al. [4] and Namboodiri et al. [5] the direct closure of the orifice located outside the LV and outside the LV under thoracotomy or could be the available, safe and less invasive approach to do. On the contrary, Honda and colleagues [6] supported the conventional approach and surgical technique by closing the pseudoaneurysm with a patch and the median sternotomy approach (Table 2). The early surgical repair is often the recommended treatment, in particularly if the heart failure is present and the pseudoaneurysm size is more than 3 cm in diameter (Table 2) in order to reduce the risk of rupture or infection or compression of neighboring structures. Therefore, the most incidence of SLVP are in patient with a clinical history of previous cardiac surgery, hence the less invasive approach could be the safer and the more effective. Moreover a ...

A subclavian artery aneurysm associated with Neurofibromatosis type 1 (NF 1) is extremely rare. We report a ruptured pseudo-aneurysm of the subclavian artery in a patient with NF 1 treated with endovascular surgery. A 51 year old man with NF 1 presented with initially sudden left neck pain and continuous dysphagia. Radiological examination showed a pseudo-aneurysm of the left subclavian artery. Endovascular stenting and coil embolisation was performed to prevent rebleeding and the lesion was completely obliterated. Follow-up angiography at 3 months revealed good flow through the stent without flow into the pseudo-aneurysm. Our patient is the first reported example of successful endovascular treatment for a ruptured subclavian artery pseudo-aneurysm associated with NF 1. Endovascular stenting and coil embolisation for the ruptured subclavian artery pseudo-aneurysm was very effective ...

Left ventricular aneurysms (LVAs) and pseudoaneurysms are two complications of myocardial infarction (MI) that can lead to death or serious morbidity.An LVA is most commonly the result of MI, usually involving the anterior wall. Other causes of LVA i
The aim of this study is to report a new minimally invasive technique of superficial temporal artery (STA) pseudoaneurysm treatment. Several surgical options have been employed to treat STA pseudoaneurysms. To address this rare condition, the employed techniques are ligation and excision of the aneurysm, endovascular coil embolization or percutaneous ultrasound-guided thrombin injection. Between techniques no significant differences are reported in terms of outcomes. The decision to adopt a technique depends on STA pseudoaneurysm morphology and surgeon preference. In the present report, STA pseudoaneurysm afferent and efferent branches were identified by ultrasound in a 92-year-old female. Under local anaesthesia, these branches were ligated through small skin incisions. STA pseudoaneurysm decompression was obtained by an over the needle aspiration. A compressive dressing was left in space for 48 h. ...

Table) Ninety-one patients had superficial thrombin injection (STI) and 55 patients had neck thrombin injection (NTI). Baseline characteristics were similar in both groups. At the time of injection, all patients were on dual antiplatelet therapy and 9.6% were on oral anti-coagulation therapy without significant difference between both groups. Patients in the NTI cohort tended to have shorter neck. The NTI technique utilized lesser amount of Thrombin with a trend to a higher success rate and lesser recurrence. The two patients in the NTI group with recurrent PSA on follow-up imaging study were both on Coumadin and both PSAs were successfully treated with re-injection of Thrombin. No serious complications were observed including thromboembolism, limbischemia, aneurysm rupture, or abscess formation. ...

A 52-year-old man presented with signs of a right middle cerebral artery stroke. A large pulsatile mass was noted at the right base of his neck, together with an overlying scar which the patient reported as being due to a stab wound sustained 22 years ago (Fig. 1). A computed tomography (CT) scan of the brain showed an infarct in the area of the right middle cerebral artery (Fig. 2). Computed tomographic angiography revealed a pseudo-aneurysm of the right common carotid artery at its origin with extensive surrounding thrombus (Fig. 3), as well as paucity of branches of the right middle cerebral artery (Fig. 4). Definitive management of the pseudo-aneurysm was achieved by vascular surgical intervention.

In this brief report, we describe a technique to facilitate hypothermic arrest before a redo sternotomy that is likely to require extensive dissection. This approach may be well-suited for patients with significant aortic insufficiency, as it allows control of left ventricular distention once hypothermic ventricular fibrillation ensues. The procedure entails inserting a second venous cannula through the left ventricular apex through a 7-cm left mini-thoracotomy. We used the technique successfully in a patient with a ruptured, infected ascending aortic pseudoaneurysm and severe aortic insufficiency who had undergone a previous sternotomy. ...
The authors identified two randomized controlled trials, one observational study with a control group, and nine observational studies without a control group. A total of five different catheters were used across these trials. In controlled studies, there was a reduction in mean systolic (-28.9 mm Hg; 95% confidence interval [CI], -37.2 to -20.6; p < 0.0001) and diastolic (-11.0 mm Hg; 95% CI, -16.4 to -5.7; p < 0.0001) blood pressure (BP) at 6 months compared to medically treated patients. In uncontrolled studies, there was a similar reduction in mean systolic (-25.0 mm Hg; 95% CI, -29.9 to -20.1) and diastolic (-10.0 mm Hg; 95% CI, -12.5 to -7.5) blood pressure at 6 months compared to pre-RDN values. There was no difference in the effect of RDN according to the type of the device used. Reported procedural complications included one renal artery dissection and four femoral pseudoaneurysms.. ...

Vasculo-Behçet disease iVBD jis a special type of Behçet disease iBD jinvolving some vascular disorders like aneurysmal formation, arterial occlusion, and venous thrombosis in various vessels. VBD has a poor prognosis due to aneurysmal rupture or recurrence of vascular disorders despite optimal treatment. However, definite diagnosis in BD is made on the basis of clinical features, and early diagnosis is difficult. We report 2 patients whose first clinical symptoms were femoral-pseudoaneurysms. They received a diagnosis of VBD after surgery. The first patient was a 69-year-old man, who underwent autologous-vein patch closure of a perforated region in the left femoral artery. One year later, he had a pseudoaneurysm of the right profunda femoris artery, which was ligated. The second patient was a 51-year-old man, who underwent the interposition of the saphenous vein for defective artery due to left superficial femoral-pseudoaneurysm ...
