Infrainguinal revascularisation in the era of vein-graft surveillance--do clinical factors influence long-term outcome? (1/2458)

OBJECTIVES: To investigate the variables affecting the long-term outcome of infrainguinal vein bypass grafts that have undergone postoperative surveillance. DESIGN: A retrospective analysis. PATIENTS AND METHODS: Details of 299 consecutive infrainguinal vein grafts performed in 275 patients from a single university hospital were collected and analysed. All grafts underwent postoperative duplex surveillance. Factors affecting patency, limb salvage and survival rates were examined. These factors were gender, diabetes, hypertension, aspirin, warfarin, ischaemic heart disease, run-off, graft type, early thrombectomy, level of anastomoses and indication for surgery. RESULTS: The 6-year primary, primary assisted and secondary patency rates were 23, 47, and 57%, respectively. Six-year limb salvage and patient survival were 68 and 45%, respectively. Primary patency was adversely influenced by the use of composite vein grafts. Early thrombectomy was the only factor that significantly influenced secondary patency. Limb salvage was worse in diabetic limbs, limbs with poor run-off and in grafts that required early thrombectomy. Postoperative survival was better in males, claudicants and in patients who took aspirin. CONCLUSIONS: Although co-morbid factors did not influence graft patency rates, diabetes did adversely effect limb salvage. This study, like others before it, confirms that aspirin significantly reduces long-term mortality in patients undergoing infrainguinal revascularisation.  (+info)

Isolated femoropopliteal bypass graft for limb salvage after failed tibial reconstruction: a viable alternative to amputation. (2/2458)

PURPOSE: Femoropopliteal bypass grafting procedures performed to isolated popliteal arteries after failure of a previous tibial reconstruction were studied. The results were compared with those of a study of primary isolated femoropopliteal bypass grafts (IFPBs). METHODS: IFPBs were only constructed if the uninvolved or patent popliteal segment measured at least 7 cm in length and had at least one major collateral supplying the calf. When IFPB was performed for ischemic lesions, these lesions were usually limited to the digits or small portions of the foot. Forty-seven polytetrafluoroethylene grafts and three autogenous reversed saphenous vein grafts were used. RESULTS: Ankle brachial pressure index (ABI) increased after bypass grafting by a mean of 0.46. Three-year primary life table patency and limb-salvage rates for primary IFPBs were 73% and 86%, respectively. All eight IFPBs performed after failed tibial bypass grafts remained patent for 2 to 44 months, with patients having viable, healed feet. CONCLUSION: In the presence of a suitable popliteal artery and limited tissue necrosis, IFPB can have acceptable patency and limb-salvage rates, even when a polytetrafluoroethylene graft is used. Secondary IFPB can be used to achieve limb salvage after failed tibial bypass grafting.  (+info)

Superficial femoral eversion endarterectomy combined with a vein segment as a composite artery-vein bypass graft for infrainguinal arterial reconstruction. (3/2458)

OBJECTIVE: The purpose of this study was to determine the results of composite artery-vein bypass grafting for infrainguinal arterial reconstruction. METHODS: This study was designed as a retrospective case series in two tertiary referral centers. Forty-eight of 51 patients underwent the procedure of interest for the treatment of ischemic skin lesions (n = 42), rest pain (n = 3), disabling claudication (n = 1), and infected prosthesis (n = 2). The intervention used was infrainguinal composite artery-vein bypass grafting to popliteal (n = 18) and infrapopliteal (n = 30) arteries, with an occluded segment of the superficial femoral artery prepared with eversion endarterectomy and an autogenous vein conduit harvested from greater saphenous veins (n = 43), arm veins (n = 3), and lesser saphenous veins (n = 2). The main outcome measures, primary graft patency rates, foot salvage rates, and patient survival rates, were described by means of the life-table method for a mean follow-up time of 15.5 months. RESULTS: The cumulative loss during the follow-up period was 6% and 24% at 6 and 12 months, respectively. The primary graft patency rates, the foot salvage rates, and the patient survival rates for patients with popliteal grafts were 60.0% +/- 9.07%, 75.7% +/- 9.18%, and 93.5% +/- 6.03%, respectively, at 1 month; 53.7% +/- 11.85%, 68.9% +/- 12.47%, and 85. 0% +/- 9.92% at 1 year; and 46.7% +/- 18.19%, 68.9% +/- 20.54%, and 53.1% +/- 17.15% at 5 years. For infrapopliteal grafts, the corresponding estimates were 72.4% +/- 7.06%, 72.9% +/- 6.99%, and 92.7% +/- 4.79% at 1 month; 55.6% +/- 10.70%, 55.4% +/- 10.07%, and 77.9% +/- 9.02% at 1 year; and 33.6% +/- 22.36%, 55.4% +/- 30.20%, and 20.8% +/- 9.89% at 5 years. CONCLUSION: The composite artery-vein bypass graft is a useful autogenous alternative for infrainguinal arterial reconstruction when a vein of the required quality is not available or when the procedure needs to be confined to the affected limb.  (+info)

The value of late computed tomographic scanning in identification of vascular abnormalities after abdominal aortic aneurysm repair. (4/2458)

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)

Right atrial bypass grafting for central venous obstruction associated with dialysis access: another treatment option. (5/2458)

PURPOSE: Central venous obstruction is a common problem in patients with chronic renal failure who undergo maintenance hemodialysis. We studied the use of right atrial bypass grafting in nine cases of central venous obstruction associated with upper extremity venous hypertension. To better understand the options for managing this condition, we discuss the roles of surgery and percutaneous transluminal angioplasty with stent placement. METHODS: All patients had previously undergone placement of bilateral temporary subclavian vein dialysis catheters. Severe arm swelling, graft thrombosis, or graft malfunction developed because of central venous stenosis or obstruction in the absence of alternative access sites. A large-diameter (10 to 16 mm) externally reinforced polytetrafluoroethylene (GoreTex) graft was used to bypass the obstructed vein and was anastomosed to the right atrial appendage. This technique was used to bypass six lesions in the subclavian vein, two lesions at the innominate vein/superior vena caval junction, and one lesion in the distal axillary vein. RESULTS: All patients except one had significant resolution of symptoms without operative mortality. Bypass grafts remained patent, allowing the arteriovenous grafts to provide functional access for 1.5 to 52 months (mean, 15.4 months) after surgery. CONCLUSION: Because no mortality directly resulted from the procedure and the morbidity rate was acceptable, this bypass grafting technique was adequate in maintaining the dialysis access needed by these patients. Because of the magnitude of the procedure, we recommend it only for the occasional patient in whom all other access sites are exhausted and in whom percutaneous dilation and/or stenting has failed.  (+info)

Infrarenal endoluminal bifurcated stent graft infected with Listeria monocytogenes. (6/2458)

Prosthetic graft infection as a result of Listeria monocytogenes is an extremely rare event that recently occurred in a 77-year-old man who underwent endoluminal stent grafting for infrarenal abdominal aortic aneurysm. The infected aortic endoluminal prosthesis was removed by means of en bloc resection of the aneurysm and contained endograft with in situ aortoiliac reconstruction. At the 10-month follow-up examination, the patient was well and had no signs of infection.  (+info)

Endovascular stent graft repair of aortopulmonary fistula. (7/2458)

Two patients who had aortopulmonary fistula of postoperative origin with hemoptysis underwent successful repair by means of an endovascular stent graft procedure. One patient had undergone repeated thoracotomies two times, and the other one time to repair anastomotic aneurysms of the descending aorta after surgery for Takayasu's arteritis. A self-expanding stainless steel stent covered with a Dacron graft was inserted into the lesion through the external iliac or femoral artery. The patients recovered well, with no signs of infection or recurrent hemoptysis 8 months after the procedure. Endovascular stent grafting may be a therapeutic option for treating patients with aortopulmonary fistula.  (+info)

Frame dislocation of body middle rings in endovascular stent tube grafts. (8/2458)

OBJECTIVES: To understand the cause, and propose a mechanism for frame dislocation in endovascular grafts. MATERIALS AND METHODS: Five tube grafts were explanted due to secondary distal leakage 15-21 months after operation. One bifurcated graft was removed during emergency operation after aortic rupture caused by secondary leakage. A second bifurcated graft was harvested from a patient with thrombotic occlusion of one limb, who died after transurethral prostatic resection. The inside of the grafts were examined endoscopically. The stent was inspected after removal of the fabric, broken ligatures were counted and examined by scanning electron microscopy. The fabric strength was tested by probe puncture. RESULTS: We found 17-44% of the stent ligatures of the body middle rings to be loose. The knots were intact. Degradation of the polyester textile was not observed. CONCLUSIONS: Continuous movements in the grafted aorta and blood pressure impose permanent stress to the stent frame and the polyester fabric resulting in morphological changes in the body middle ring of grafts. The clinical implications of the suture breakages are unknown although they may be related to distal secondary leakage in tube grafts.  (+info)

A novel endovascular approach useful in the treatment of aneurysms, particularly saccular aneurysms. The present endovascular prosthesis comprises a leaf portion capable of being urged against and blocking the opening of the aneurysm thereby leading to obliteration of the aneurysm. The leaf portion is attached to, and independently moveable with respect to, a body comprising at least one expandable portion. Thus, the body serves the general purpose of fixing the endovascular prosthesis in place at a target body passageway in the vicinity at which the aneurysm is located and the leaf portion serves the purpose of blocking the aneurysmal opening thereby leading to obliteration of the aneurysm. A method of delivering and implanting the endovascular prosthesis is also described.

Process for forming a multilayer blood vessel prosthesis. Each layer is formed from bioreplaceable materials which include those produced by contacting collagen with an aminopolysaccharide and subsequently covalently crosslinking the resulting polymer, polymers of hydroxyacetic acid and the like. Cross flow filtration molding and wet extrusion molding are two processes which are particularly useful for forming the inner layer of the blood vessel prosthesis. The outer layer of the blood vessel prosthesis is preferably formed by freeze drying a dispersion of the bioreplaceable material onto the inner layer(s). The disclosed blood vessel prosthesis is a multilayer structure with each layer having a porosity and other physicochemical and mechanical characteristics selected to maximize the effectiveness of the blood vessel. The prosthesis functions initially as a thromboresistant conduit with mechanical properties which match those of the adjacent natural blood vessel. Eventually, the prosthesis

Cardiovascular disease is the leading cause of death worldwide, accounting for 29% of all global deaths and is set to rise to 23 million deaths a year by 2030 (World Health Organisation, 2012). Arterial bypassing, both peripheral and coronary, is usually performed with autologously harvested vessels. However, the quantity available is often very limited as well as the vessels of elderly patients often suffering from thrombus, aneurysm formation or arthrosclerosis in high pressure arterial sites. The shortcomings of autografts has led to a substantial amount of research being directed towards tissue engineered vascular grafts (TEVGs) (Kakisis et al., 2005). Currently available artificial grafts for small diameter vasculature (mm) suffer from poor patency rates due to thrombosis, aneurysm formation, and a compliance mismatch, which often stems from the inherent properties of synthetic polymers. The primary goal of the research presented in this thesis was to develop a small diameter tissue engineered

The failure of synthetic vascular grafts due to de-endothelialization of the lumen as a result of exposure to fluid-induced shear stress prevents the widespread use of such grafts as small-diameter vessel replacements. Physical surface modification, an approach that seeks to alter the topography of the luminal surface, has been investigated as a method of reducing de-endothelialization under physiological stresses. Based on prior experimental evidence supporting this approach, computation fluid dynamics was used to investigate the impact of selected channel geometry parameters (wall angle, channel width, depth, and radius of curvature) on fluid flow and the resulting wall shear stress. Optimization of these parameters was performed in order to determine if micro-topographical modification of the lumen wall could alter fluid flow in a manner such that favorable conditions for both endothelial cell retention and stimulation are produced. It was found that a 50% decrease in the wall angle, width, ...

Introduction: Endovascular aneurysm repair (EVAR) has been an established treatment for abdominal aortic aneurysm (AAA). Although statin use has been shown associated with better long-term survival following open AAA surgery, its impact on EVAR has not been systematically explored.. Methods: We retrospectively analyzed a multicenter database of 368 consecutive patients (age, 76 ± 8 years; 84% male) undergoing EVAR for AAA between November 2006 and December 2013. The outcome measure was overall survival following EVAR. Independent predictor associated with the outcome was assessed by Cox proportional hazard regression model. Furthermore, the association between the statin use and the outcome was assessed.. Results: During the follow-up of 30 ± 20 months, 38 patients died from cardiovascular disease (33%), cancer (23%) or infection (23%). Survival rate was 96% and 81% at 1 and 5 years, respectively. In Cox regression analysis, statin use (in 213 AAA patients, 58%) was negatively associated with ...
This is the first article to our knowledge to report the use of biophysical forces to attach endothelial cells to the surface of prosthetic vascular grafts. EOCs readily endocytose paramagnetic particles and are rapidly attracted to magnetized graft surfaces. Once seeded, these cells remain attached at shear forces comparable to those seen in the circulation. A porcine study provided proof of concept and demonstrated the presence of a large number of seeded cells after 24 hours of pulsatile blood flow.. Vascular grafts based on either expanded polytetrafluoroethylene or polyethylene terephthalate fiber (Dacron) work very well when positioned in vessels with diameters ,6 mm and in conditions of high flow. However, the majority of vascular disease occurs in vessels with caliber of ,6 mm. Coronary bypass grafting is commonly performed with arterial conduits (when available), and with autologous saphenous vein grafts. However, up to 30% of the patients do not have veins suitable for vascular ...

September 28, 2017-The US Food and Drug Administration (FDA) has issued a letter to health care providers advising that the agency is evaluating recent information regarding type IIIa and IIIb endoleaks with the use of endovascular graft systems indicated for endovascular aneurysm repair (EVAR) procedures. The letter, addressed to vascular and cardiothoracic surgeons, radiologists, and cardiologists, stated that an increase in the occurrence of type III endoleaks has been suggested by several sources, including the FDAs Medical Device Reporting system and the Annual Clinical Updates to Physicians by the manufacturers. This increase is compared with earlier clinical update reports in patients with various device models and implant duration lengths, including some patients who had previously stable repairs.. The purpose of the FDAs letter is to bring this potential complication to the attention of health care providers and to remind and encourage them to report type IIIa and IIIb endoleak events ...
Fenestrated and branched endovascular aortic repair (F/B-EVAR) is associated with a high degree of technical and clinical success. Despite this, studies have also reported high reintervention rates, and these are often related to the bridging stent grafts. Often new devices appear on the market before they have been tested in the bridging stent graft position. This review aims to assess the current literature on bridging stent grafts and discuss complications, illustrated by case reports. Complications reported with bridging stent grafts include; endoleak, kink, fracture, migration, occlusion, stenosis and perforation. Some known risk factors for bridging stent occlusions are renal artery stent grafts vs. SMA and celiac artery stent grafts.

PURPOSE: To report 5-year results of the prospective, multicenter study designed to evaluate the Zenith Fenestrated AAA Endovascular Graft (William A. Cook Australia, Brisbane, Australia) for juxtarenal abdominal aortic aneurysms (AAAs). METHODS: Sixty-seven patients (54 male, mean age 74 ± 8 years) were prospectively enrolled at 14 U.S. centers from 2005 to 2012. Fenestrated stent grafts were used in patients with infrarenal aortic neck lengths of 4 to 14 mm to target 178 renal-mesenteric arteries with a mean of 2.7 vessels per patient. At 5 years, 42 of the 67 patients completed the final study follow-up, with clinical examination obtained in 41 and computed tomography imaging in 39. Outcomes adjudicated by a clinical events committee included all-cause and aneurysm-related mortality, major adverse events, renal stent occlusion/stenosis, renal function changes and renal infarcts, aneurysm sac enlargement (>5 mm), device migration (≥10 mm), type I/III endoleak, and secondary interventions. ...
Medtronic Receives FDA Breakthrough Device Designation for Developing Stent Graft System to Treat Thoracoabdominal Aortic Aneurysm - - Minneapolis (Minnesota)
A major dilemma faced by a surgeon in view of a vascular graft infection is the selection of treatment. Currently it is commonly agreed that the removal of the infected graft and a concurrent vascular reconstruction is the best method. While surgical removal of the infected graft does not raise concerns in most cases, the reconstruction stage is associated with the necessity of selecting the optimal location of the reconstructed vascular bed (extra-anatomical bypass or in situ bypass graft) together with the material necessary for its formation (autologous vessels, cadaver homograft, silver-coated grafts or antibiotic-soaked vascular grafts).. The authors also encountered the problems presented above based on the case of a 73-year-old patient with a massive infection of a dacron aortobifemoral vascular graft. The patient was initially operated on due to symptomatic Leriche syndrome with ischemia of both lower extremities stage III°, according to the Fontaines scale (20-30m intermittent ...
Background: Bypass graft thrombosis remains a significant mode of failure in prosthetic graft revascularization. The purpose of this investigation was to evaluate the long-term thromboresistant effect of heparin-bonded expanded polytetrafluoroethylene (ePTFE) graft using Carmeda BioActive Surface technology in a canine model. Methods: Bilateral femorofemoral artery bypass grafts with ePTFE grafts were performed in 25 adult grayhound dogs. In each animal, a heparin-bonded ePTFE graft (Propaten, WL Gore) was placed on one side, whereas a control nonheparin graft was placed on the contralateral side. The graft patency was assessed at 1, 6, 12, 18, and 24 months (n = 5 per group) following the bypass. Heparin bioactivity of the graft material was analyzed. The effect of intimal hyperplasia was also assessed. Results: All bypass grafts were patent at 1 month. Significantly greater patency rates were noted in the Propaten group compared to the control group at 12, 18, and 24 months, which were 84%, ...
Infections of the aorta remain one of the most dreaded complications in reconstructive vascular surgery. The purposes of this study were to evaluate the efficacy of a cryopreserved aortic allograft to treat an established vascular graft infection by the surgical in situ replacement of the infected segment in an animal model, and to investigate the role of antibiotics to decontaminate the allograft during the cryopreservation process. Furthermore, the tissue concentrations of the antibiotic and the kinetics of desorption were investigated in in vitro experiments. A model of prosthetic graft infection by Staphylococcus epidermidis RP-62 (inserted in the infrarenal aorta) in dogs was developed. By in situ replacement of the infected prosthetic graft with a cryopreserved aortic allograft, this study demonstrated an intrinsic resistance to infection of cryopreserved aortic allografts. However, antibiotic loading of the cryopreserved aortic allografts appeared to be essential to obtain optimal ...

The Endurant II AAA stent graft (Medtronic) is a stent-graft composed with highly elastic nitinol stents with a high-density polyester fiber. Nitinol is an alloy of titanium and nickel and has been shown to have several advantages which include greater resistance to crushing forces as well as lower bending stress when placed within tortuous vessels (which is sometimes the case with aortic aneurysms).. Nitinol is also safe with use of magnetic resonance imaging (MRI). The Endurant stent graft system is often employed in challenging endovascular repairs (e.g. close proximity of the aneurysm to the renal arteries or tortuous aorta). Even while including results from difficult repairs, studies have shown that success and complication rates are comparable to other stent grafts. ...

Objective: The purpose of this study was to report prospective data of an off-the-shelf fenestrated endograft (Zenith p-Branch; Cook Medical, Bloomington, Ind) from four centers for the treatment of patients with pararenal abdominal aortic aneurysms. Methods: Data were combined from four single-center investigational studies conducted in the United States and Europe. The p-Branch endograft consists of a proximal off-the-shelf component incorporating a scallop for the celiac artery, a superior mesenteric artery fenestration, and two conical pivot fenestrations to preserve flow to the renal vessels. The device is available in two configurations, a left renal fenestration at the same (configuration A) or lower (configuration B) longitudinal position than the right to accommodate varied anatomy of the patients. Results: Between August 2011 and September 2015, 76 patients (82% male; mean age, 72 years; 65 elective and 11 emergent) were enrolled, with 55% implanted with option A and 45% with B. The ...

A vascular graft comprised of a tubular polytetrafluoroethylene (ePTFE) sheet is provided. The ePTFE sheet has a substantially uniform coating of bioresorbable gel material, for example gelatin, on a surface thereof. The coating minimises bleeding through suture holes in the ePTFE sheet and provides an increase in longitudinal extensibility.
Despite medical achievements, the number of patients with end-stage kidney disease keeps steadily raising, thereby entailing a high number of surgical and interventional procedures to establish and maintain arteriovenous vascular access for hemodialysis. Due to vascular disease, aneurysms or infection, the preferred access-an autogenous arteriovenous fistula-is not always available and appropriate. Moreover, when replacing small diameter blood vessels, synthetic vascular grafts possess well-known disadvantages. A continuous multilayered gradient electrospinning was used to produce vascular grafts made of collagen type I nanofibers on luminal and adventitial graft side, and poly-ɛ-caprolactone as medial layer. Therefore, a custom-made electrospinner with robust environmental control was developed. The morphology of electrospun grafts was characterized by scanning electron microscopy and measurement of mechanical properties. Human microvascular endothelial cells were cultured in the graft under ...

Porous expanded polytetrafluoroethylene material having a microstructure of nodes interconnected by fibrils wherein a surface of the material has been modified to have increased hydrophobicity as indicated by having a water droplet roll-off angle of less than about 10 degrees in comparison to a typical roll-off angle of greater than about 12 degrees for the unmodified material. Under magnification, the surface morphology may be indistinguishable from that of the unmodified precursor material. The modification is preferably done by exposing the surface to radio frequency gas plasma discharge with a reactive etching gas for a lengthy amount of time such as about ten minutes. If surface etching is continued beyond a time adequate to produce the highly hydrophobic behavior, then the surface morphology includes the appearance of broken fibrils. Still further treatment results in complete removal of fibrils from the surface so that under magnification the surface has the appearance of freestanding node

The treatment of thoracic aortic TSXN with endografts presents several technical challenges. The most important is the lack of a dedicated device for these patients. All commercially available aortic endografts, especially those for use in the thoracic aorta, were designed for treatment of aneurysms and dissections. These pathologies usually occur in older individuals with intrinsic arterial disease and larger diameter aortas. The smallest commercially available thoracic aortic endograft, the Gore TAG device (W.L. Gore & Associates, Flagstaff, AZ) is 26 mm diameter, and is not recommended for use in aortas less than 23 mm in diameter [12]. One concern with excessive endograft oversizing is in-folding of the graft material that prevents an adequate seal against the aortic intima. Of greater concern, graft collapse has been reported when this device is used in aortas smaller than 23 mm diameter to treat an aortic TSXN [2,6]. The mechanism of graft collapse is unclear but this complication has also ...

  • The main reason to consider a reverse prosthesis is when there is arthritis of the shoulder joint and the rotator cuff tendons are torn or gone. (
  • A hip replacement is a surgical procedure where an injured or damaged hip joint is replaced with an artificial hip joint known as a prosthesis. (
  • Reoperation of a total hip replacement to resolve a painful hip condition and loss of motion due to a loosened prosthesis (artificial hip joint) is known as correction of a loose hip replacement. (
  • Another risk is injury to the blood vessels and the nerves around the hip joint, which is pretty rare. (
  • The fracture can tear the blood vessels and cut off the blood supply to the femoral head, which is the "ball" of the "ball-and-socket" hip joint. (
  • Ankle joint replacement is performed without significant blood loss, and the postoperative pain syndrome is not severe. (
  • Neuroprosthesis research in amputee patients aims to develop new prostheses that move and feel like real limbs. (
  • However, except for AIMS, PMMA Replacement Prosthesis has probably never been used by any other major diabetic foot centre in the world for the replacement of destroyed foot and ankle bones. (
  • Why should a person get a reverse prosthesis instead of a standard shoulder replacement? (
  • Since the advent of the vascular anastomosis by Alexis Carrel in the early 20th century, the repair and replacement of blood vessels have been key to treating acute injuries, as well as chronic atherosclerotic disease. (
  • Special distractor instruments are used to restore the normal height of the disc and to determine the appropriate size of the artificial disc replacement prosthesis. (
  • The splitting of the vessel wall in one or both (left and right) internal carotid arteries (CAROTID ARTERY, INTERNAL). (
  • Blood supply to the penis can become blocked or narrowed as a result of vascular disease such as atherosclerosis (hardening of the arteries). (
  • Not having enough blood flow to the penis - Conditions like heart disease, diabetes, and hardened arteries can all restrict the functions of an individual's circulatory system, which can prevent proper amounts of blood flow to certain areas of the body. (
  • This study is typically performed after the injection of a chemical that causes the arteries to open up, a vasodilator (prostaglandin E1), into the corpora cavernosa in order to cause dilation of blood vessels and promote blood flow into the penis. (
  • Blood flow to the corpora cavernosa is via the paired deep arteries of the penis (cavernosal arteries), which run near the center of each corpora cavernosa (see the following image). (
  • For proximal femoral reconstruction, the estimated 5-year modular prosthesis survival rate was 90.7 % and the mean Toronto Extremity Salvage (TES) score was 61 % [ 9 ]. (
  • The muscles around the shoulder also help keep the reverse prosthesis in place. (
  • They work by relaxing the muscles in the penis, which allows for increased blood flow. (
  • It is attached to the muscles that control movement, so when Cass looks up with her good eye, the prosthesis also "looks up. (
  • Impulses from the brain and local nerves cause the muscles of the corpora cavernosa to relax, allowing blood to flow in and fill the open spaces. (
  • Erection is reversed when muscles in the penis contract, stopping the inflow of blood and opening outflow channels. (
  • The abdominal muscles, blood vessels and peritoneal sac (containing the intestines) are gently pushed or moved aside using special retractors. (
  • This disease is classified into organic impotence caused by disorders in the nerves, blood vessels or muscles in the penis per se or sexual hormones and functional (psychic) impotence caused by mental or psychologic troubles. (
  • Center Penile erection is a complex process in which the brain, nerves, muscles and blood vessels play a major role. (
  • The most successful method for controlling a prosthesis to date is a surgical procedure in which nerves that were previously attached to muscles in a lost arm and hand are transplanted into the chest. (
  • These drugs not only affect and often suppress the central nervous system, but can also cause serious damage to the blood vessels, leading to permanent ED. (
  • Surgical drains are placed for the excess blood to drain out and the incision is closed. (
  • Lower limb prostheses worn by amputee subjects during running. (
  • The fracture may heal, but the blood vessels don't. (
  • Your doctor will perform a careful physical exam to ensure blood vessels and nerves passing near the fracture site have not been injured. (
  • When the fracture line crosses the tip of the prosthesis and extends towards the elbow, open reduction and internal fixation (ORIF) of the fracture may be required. (
  • However, fixation of periprosthetic shoulder fractures can be very complicated, and each case is treated individually, depending on the severity of the fracture and the condition of the prosthesis. (
  • The part of the fixation of the prosthesis was tested by the author with nylon and drilling on the tibia, made with drills. (
  • Age & Gender: Young male Condition Presented: Severe lymph oedema and swelling to left lower leg due to and injury to the blood and lymph vessels 1 year prior. (
  • This helps them make a temporary leg prosthesis that you can wear soon after the procedure. (
  • Requirements of the surgical procedure are determined and necessary preoperative preparations are carried out, such as reserving blood, requesting consultations, giving nutritional advice and management of pain killers and drugs. (
  • If CoroFlow ‡ is used together with 3rd party infusion catheters for assessment of Absolute Flow and Resistance, ensure that the maximum infusion rate per manufacturers instruction is not exceeded or vessel injury may occur. (
  • It can show brain and spinal trauma from injury, herniated discs (cartilage located between the vertebrae), vascular (blood vessel) irregularities, bleeding, inflammation that might compress the spine and spinal cord, and injury to the ligaments that support the cervical spine. (
  • Being a disease of the blood vessels diabetes affects all organs. (
  • The blood vessels get weaken and do not flow properly to the penis for its erection. (
  • The tunica albuginea helps to trap the blood in the corpora cavernosa, thereby sustaining erection. (
  • PulseWave therapy uses low-intensity sound waves to naturally enhance blood flow to your penis, allowing you to achieve and maintain a firmer erection. (
  • It may also be difficult for an individual to keep blood in the penis long enough to sustain an erection. (
  • A rubber ring placed at the base of the penis helps to maintain the blood maintaining the erection. (
  • Most such patients have been fitted with - and mastered - sophisticated mechanical prostheses. (
  • Its principle of action is to increase blood flow to the genitals, under the pressure of which the chambers of the corpora cavernosa expand and the penis stretches over time. (
  • The blood creates pressure in the corpora cavernosa, making the penis expand. (
  • Although modular prosthesis is commercially available to meet requirements in most limb salvage surgeries, customized prosthesis is still needed. (
  • In recent years, the modular prosthesis has been developed and extensively used in limb salvage surgeries due to being readily available. (
  • They will then hollow out the inside of the femur, where they will place the metal stem of the prosthesis. (
  • Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the internal carotid artery and aneurysm formation. (
  • With the help of an interventional radiologist, on can perform intravascular interventions, multiple puncture embolization (blocking of blood vessels), occlusion, aneurysm clipping, and others. (
  • The three factors of Virchow's triad--venous stasis, hypercoagulability, and changes in the endothelial blood vessel lining (such as physical damage or endothelial activation)--contribute to DVT and are used to explain its formation. (
  • The use of prosthesis in a patient living with diabetes increases the cardiac strain to over 15%, leading to cardiac failure over a period of time. (

  • A blood clot can be a life-changing diagnosis for many people, and the path to healing is a little bit different for everyone. (
  • It's important to keep your head raised, rest a lot, and move your legs from time to time to improve blood flow. (
  • They work by creating a vacuum around the penis, which allows for increased blood flow. (
  • Quitting smoking, losing weight, and exercising regularly can all help to improve blood flow and reduce stress. (
  • There are four heart valves in the heart that regulate blood flow, opening and closing in turn. (
  • As a result, the blood flow is disturbed, and the heart begins to work less efficiently. (
  • With the vascular nature of impotence, when blood flow to the penis is disrupted, operations are performed on vessels and cavernous bodies. (
  • Any disorder that impairs blood flow in the penis has the potential to cause impotence. (
  • The pulsating waves of GAINSWave improves blood flow to the penis by dissolving plaque build-up and stimulating the growth of new blood vessels. (
