Infrainguinal revascularisation in the era of vein-graft surveillance--do clinical factors influence long-term outcome? (1/2062)

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. (2/2062)

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. (3/2062)

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.

Surgical transluminal iliac angioplasty with selective stenting: long-term results assessed by means of duplex scanning. (4/2062)

PURPOSE: The safety of iliac angioplasty and selective stenting performed in the operating room by vascular surgeons was evaluated, and the short- and long-term results were assessed by means of serial duplex scanning. METHODS: Between 1989 and 1996, 281 iliac stenotic or occlusive lesions in 235 consecutive patients with chronic limb ischemia were treated by means of percutaneous transluminal angioplasty (PTA) alone (n = 214) or PTA with stent (n = 67, 23.8%). There were 260 primary lesions and 21 restenosis after a first PTA, which were analyzed separately. Stents were implanted in selected cases, either primarily in totally occluded arteries or after suboptimum results of PTA (ie, residual stenosis or a dissection). Data were collected prospectively and analyzed retrospectively. Results were reported in an intention-to-treat basis. Clinical results and patency were evaluated by means of symptom assessment, ankle brachial pressure index, and duplex scanning at discharge and 1, 3, 6, and every 12 months after angioplasty. To identify factors that may affect outcome, 12 clinical and radiological variables, including the four categories of lesions defined by the Standards of Practice Committee of the Society of Cardiovascular and Interventional Radiology, were analyzed separately. The statistical significances of life-table analysis of patency were determined by means of the log-rank test. RESULTS: There were no postoperative deaths or amputations. Local, general, and vascular complications occurred in 2.1%, 1.3% and 4.7% of cases, respectively (total, 8.1%). The mean follow-up period was 29.6 months. The cumulative patency rates +/- SE of the 260 PTAs (including 55 PTAs plus stents) were 92.9% +/- 1.5% at 1 month, 86. 5% +/- 1.7% at 1 year, 81.2% +/- 2.3% at 2 years, 78.8% +/- 2.9% at 3 years, and 75.4% +/- 3.5% at 5 and 6 years. The two-year patency rate of 21 redo PTAs (including 11 PTAs plus stents) was 79.1% +/- 18.2%. Of 12 predictable variables studied in the first PTA group, only the category of the lesion was predictive of long-term patency. The two-year patency rate was 84% +/- 3% for 199 category 1 lesions and 69.7% +/- 6.5% for 61 category 2, 3, and 4 lesions together (P =. 02). There was no difference of patency in the stented and nonstented group. CONCLUSION: Iliac PTA alone or with the use of a stent (in cases of occlusion and/or suboptimal results of PTA) offers an excellent long-term patency rate. Categorization of lesions remains useful in predicting long-term outcome. PTA can be performed safely by vascular surgeons in the operating room and should be considered to be the primary treatment for localized iliac occlusive disease. (+info)

Right atrial bypass grafting for central venous obstruction associated with dialysis access: another treatment option. (5/2062)

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.

Relief of obstructive pelvic venous symptoms with endoluminal stenting. (6/2062)

PURPOSE: To select patients for percutaneous transluminal stenting of chronic postthrombotic pelvic venous obstructions (CPPVO), we evaluated the clinical symptoms in a cohort of candidates and in a series of successfully treated patients. METHODS: The symptoms of 42 patients (39 women) with CPPVO (38 left iliac; average history, 18 years) were recorded, and the venous anatomy was studied by means of duplex scanning, subtraction venography, and computed tomography or magnetic resonance imaging. Successfully stented patients were controlled by means of duplex scanning and assessment of symptoms. RESULTS: The typical symptoms of CPPVO were reported spontaneously by 24% of patients and uncovered by means of a targeted interview in an additional 47%. Of 42 patients, 15 had venous claudication, four had neurogenic claudication (caused by dilated veins in the spinal canal that arise from the collateral circulation), and 11 had both symptoms. Twelve patients had no specific symptoms. Placement of a stent was found to be technically feasible in 25 patients (60%), was attempted in 14 patients, and was primarily successful in 12 patients. One stent occluded within the first week. All other stents were fully patent after a mean of 15 months (range, 1 to 43 months). Satisfaction was high in the patients who had the typical symptoms, but low in those who lacked them. CONCLUSION: Venous claudication and neurogenic claudication caused by venous collaterals in the spinal canal are typical clinical features of CPPVO. We recommend searching for these symptoms, because recanalization by means of stenting is often feasible and rewarding. (+info)

Use of high-intensity focused ultrasound to control bleeding. (7/2062)

OBJECTIVE: High-intensity focused ultrasound (HIFU) has been shown to be effective in controlling hemorrhage from punctures in blood vessels. The objective of the current study was to investigate the capability of HIFU to stop bleeding after a more severe type of vascular injury, namely longitudinal incisions of arteries and veins. METHODS: The superficial femoral arteries, common femoral arteries, carotid arteries, and jugular veins of four anesthetized pigs were exposed surgically. A longitudinal incision, 2 to 8 mm in length, was produced in the vessel. HIFU treatment was applied within 5 seconds of the onset of the bleeding. The HIFU probe consisted of a high-power, 3.5-MHz, piezoelectric transducer with an ellipsoidal focal spot that was 1 mm in cross section and 9 mm in axial dimension. The entire incision area was scanned with the HIFU beam at a rate of 15 to 25 times/second and a linear displacement of 5 to 10 mm. A total of 76 incisions and HIFU treatments were performed. RESULTS: Control of bleeding (major hemosatsis) was achieved in all 76 treatments, with complete hemostasis achieved in 69 treatments (91%). The average treatment times of major and complete hemostasis were 17 and 25 seconds, respectively. After the treatment, 74% of the vessels in which complete hemostasis was achieved were patent with distal blood flow and 26% were occluded. The HIFU-treated vessels showed a consistent coagulation of the adventitia surrounding the vessels, with a remarkably localized injury to the vessel wall. Extensive fibrin deposition at the treatment site was observed. CONCLUSION: HIFU may provide a useful method of achieving hemostasis for arteries and veins in a variety of clinical applications.

Hemodialysis access: influence of the human immunodeficiency virus on patency and infection rates. (8/2062)

PURPOSE: The complication rate for patients who are dialysis dependent and infected with the human immunodeficiency virus (HIV) and the role of viral indicators (CD4 counts) as predictors of these complications are poorly characterized. To determine the influence of HIV status and viral activity on graft patency and infection rates, we retrospectively reviewed our results. METHODS: Between June 1993 and March 1997, the charts of 104 patients (HIV+, n = 42; HIV-, n = 62) who required 112 hemodialysis access grafts were reviewed. Of the 112 procedures, 55 (48%) were autologous arteriovenous fistulae (AVF) procedures (HIV+, n = 23; HIV-, n = 32) and 57 (52%) were prosthetic expanded polytetrafluoroethylene grafting procedures (HIV+, n = 27; HIV-, n = 30). Transcutaneous catheter procedures were excluded from the study. The autologous AVF procedures consisted of direct and transposed AVFs. Patency rates were determined by means of life-table analysis. Infection rates and CD4 counts were compared with the chi2 test and the Fisher exact test. Significance was accepted at a P value of.05 or less. RESULTS: The cumulative 12-month and 24-month patency rates for prosthetic grafts in patients who were HIV+ were 49% and 21%, respectively, versus 77% and 45% for patients who were HIV-. The differences in the prosthetic graft patency rates between these two groups were significant (P .05). The mean CD4+ cell counts were 174: CD4+ counts that were less than 200 did not correlate with or predict the development of infection (P >.05). CONCLUSION: Our data showed that prosthetic graft infection rates were increased and patency rates were decreased in patients who were HIV+ as compared with patients who were HIV- and HIV+ with autologous AVFs. There were no differences in patency rates or infection rates in patients who had undergone autologous access procedures. Long-term graft patency rates were not affected by HIV status, and CD4+ lymphocyte counts were not predictive of infection development. Because the prosthetic graft infection rates exceeded those rates of autologous access procedures, we recommend the vigorous use of autologous AVFs in all patients who are HIV+, regardless of CD4+ count.

Vascular patency is a term used in medicine to describe the state of a blood vessel (such as an artery or vein) being open, unobstructed, and allowing for the normal flow of blood. It is an important concept in the treatment and management of various cardiovascular conditions, such as peripheral artery disease, coronary artery disease, and deep vein thrombosis.

Maintaining vascular patency can help prevent serious complications like tissue damage, organ dysfunction, or even death. This may involve medical interventions such as administering blood-thinning medications to prevent clots, performing procedures to remove blockages, or using devices like stents to keep vessels open. Regular monitoring of vascular patency is also crucial for evaluating the effectiveness of treatments and adjusting care plans accordingly.

Fallopian tube patency tests are medical procedures used to determine whether the fallopian tubes, which are the pair of narrow tubes that connect the ovaries to the uterus in females, are open and functioning properly. The tests typically involve introducing a dye or gas into the uterus and observing whether it flows freely through the fallopian tubes and spills out of the ends.

There are several types of Fallopian tube patency tests, including:

1. Hysterosalpingogram (HSG): This is a radiologic procedure that involves injecting a dye into the uterus through the cervix while taking X-rays to observe the flow of the dye through the fallopian tubes.
2. Sonohysterography: This is an ultrasound procedure that involves injecting a sterile saline solution into the uterus through the cervix and observing the flow of the fluid through the fallopian tubes using ultrasound imaging.
3. Falloposcopy: This is a minimally invasive procedure that involves inserting a thin, flexible tube with a camera into the uterus and fallopian tubes to directly visualize their patency and any abnormalities.
4. Hysterosalpingo-contrast sonography (HyCoSy): This is an ultrasound procedure that involves injecting a contrast medium into the uterus through the cervix while observing the flow of the contrast through the fallopian tubes using ultrasound imaging.

These tests are often performed as part of an infertility evaluation to determine whether blocked or damaged fallopian tubes may be contributing to difficulty conceiving.

Graft occlusion in the context of vascular surgery refers to the complete or partial blockage of a blood vessel that has been surgically replaced or repaired with a graft. The graft can be made from either synthetic materials or autologous tissue (taken from another part of the patient's body).

Graft occlusion can occur due to various reasons, including:

1. Thrombosis: Formation of a blood clot within the graft, which can obstruct blood flow.
2. Intimal hyperplasia: Overgrowth of the inner lining (intima) of the graft or the adjacent native vessel, causing narrowing of the lumen and reducing blood flow.
3. Atherosclerosis: Deposition of cholesterol and other substances in the walls of the graft, leading to hardening and narrowing of the vessel.
4. Infection: Bacterial or fungal infection of the graft can cause inflammation, weakening, and ultimately occlusion of the graft.
5. Mechanical factors: Kinking, twisting, or compression of the graft can lead to obstruction of blood flow.

Graft occlusion is a significant complication following vascular surgery, as it can result in reduced perfusion to downstream tissues and organs, leading to ischemia (lack of oxygen supply) and potential tissue damage or loss.

An arteriovenous shunt is a surgically created connection between an artery and a vein. This procedure is typically performed to reroute blood flow or to provide vascular access for various medical treatments. In a surgical setting, the creation of an arteriovenous shunt involves connecting an artery directly to a vein, bypassing the capillary network in between.

There are different types of arteriovenous shunts used for specific medical purposes:

1. Arteriovenous Fistula (AVF): This is a surgical connection created between an artery and a vein, usually in the arm or leg. The procedure involves dissecting both the artery and vein, then suturing them directly together. Over time, the increased blood flow to the vein causes it to dilate and thicken, making it suitable for repeated needle punctures during hemodialysis treatments for patients with kidney failure.
2. Arteriovenous Graft (AVG): An arteriovenous graft is a synthetic tube used to connect an artery and a vein when a direct AVF cannot be created due to insufficient vessel size or poor quality. The graft can be made of various materials, such as polytetrafluoroethylene (PTFE) or Dacron. Grafts are more prone to infection and clotting compared to native AVFs but remain an essential option for patients requiring hemodialysis access.
3. Central Venous Catheter (CVC): A central venous catheter is a flexible tube inserted into a large vein, often in the neck or groin, and advanced towards the heart. CVCs can be used as temporary arteriovenous shunts for patients who require immediate hemodialysis access but do not have time to wait for an AVF or AVG to mature. However, they are associated with higher risks of infection and thrombosis compared to native AVFs and AVGs.

In summary, a surgical arteriovenous shunt is a connection between an artery and a vein established through a medical procedure. The primary purpose of these shunts is to provide vascular access for hemodialysis in patients with end-stage renal disease or to serve as temporary access when native AVFs or AVGs are not feasible.

Polytetrafluoroethylene (PTFE) is not inherently a medical term, but it is a chemical compound with significant uses in the medical field. Medically, PTFE is often referred to by its brand name, Teflon. It is a synthetic fluoropolymer used in various medical applications due to its unique properties such as high resistance to heat, electrical and chemical interaction, and exceptional non-reactivity with body tissues.

PTFE can be found in medical devices like catheters, where it reduces friction, making insertion easier and minimizing trauma. It is also used in orthopedic and dental implants, drug delivery systems, and sutures due to its biocompatibility and non-adhesive nature.

The popliteal artery is the continuation of the femoral artery that passes through the popliteal fossa, which is the area behind the knee. It is the major blood vessel that supplies oxygenated blood to the lower leg and foot. The popliteal artery divides into the anterior tibial artery and the tibioperoneal trunk at the lower border of the popliteus muscle. Any damage or blockage to this artery can result in serious health complications, including reduced blood flow to the leg and foot, which may lead to pain, cramping, numbness, or even tissue death (gangrene) if left untreated.

The femoral artery is the major blood vessel that supplies oxygenated blood to the lower extremity of the human body. It is a continuation of the external iliac artery and becomes the popliteal artery as it passes through the adductor hiatus in the adductor magnus muscle of the thigh.

The femoral artery is located in the femoral triangle, which is bound by the sartorius muscle anteriorly, the adductor longus muscle medially, and the biceps femoris muscle posteriorly. It can be easily palpated in the groin region, making it a common site for taking blood samples, measuring blood pressure, and performing surgical procedures such as femoral artery catheterization and bypass grafting.

The femoral artery gives off several branches that supply blood to the lower limb, including the deep femoral artery, the superficial femoral artery, and the profunda femoris artery. These branches provide blood to the muscles, bones, skin, and other tissues of the leg, ankle, and foot.

A blood vessel prosthesis is a medical device that is used as a substitute for a damaged or diseased natural blood vessel. It is typically made of synthetic materials such as polyester, Dacron, or ePTFE (expanded polytetrafluoroethylene) and is designed to mimic the function of a native blood vessel by allowing the flow of blood through it.

Blood vessel prostheses are used in various surgical procedures, including coronary artery bypass grafting, peripheral arterial reconstruction, and the creation of arteriovenous fistulas for dialysis access. The choice of material and size of the prosthesis depends on several factors, such as the location and diameter of the vessel being replaced, the patient's age and overall health status, and the surgeon's preference.

It is important to note that while blood vessel prostheses can be effective in restoring blood flow, they may also carry risks such as infection, thrombosis (blood clot formation), and graft failure over time. Therefore, careful patient selection, surgical technique, and postoperative management are crucial for the success of these procedures.

Arterial occlusive diseases are medical conditions characterized by the blockage or narrowing of the arteries, which can lead to a reduction in blood flow to various parts of the body. This reduction in blood flow can cause tissue damage and may result in serious complications such as tissue death (gangrene), organ dysfunction, or even death.

The most common cause of arterial occlusive diseases is atherosclerosis, which is the buildup of plaque made up of fat, cholesterol, calcium, and other substances in the inner lining of the artery walls. Over time, this plaque can harden and narrow the arteries, restricting blood flow. Other causes of arterial occlusive diseases include blood clots, emboli (tiny particles that travel through the bloodstream and lodge in smaller vessels), inflammation, trauma, and certain inherited conditions.

Symptoms of arterial occlusive diseases depend on the location and severity of the blockage. Common symptoms include:

* Pain, cramping, or fatigue in the affected limb, often triggered by exercise and relieved by rest (claudication)
* Numbness, tingling, or weakness in the affected limb
* Coldness or discoloration of the skin in the affected area
* Slow-healing sores or wounds on the toes, feet, or legs
* Erectile dysfunction in men

Treatment for arterial occlusive diseases may include lifestyle changes such as quitting smoking, exercising regularly, and eating a healthy diet. Medications to lower cholesterol, control blood pressure, prevent blood clots, or manage pain may also be prescribed. In severe cases, surgical procedures such as angioplasty, stenting, or bypass surgery may be necessary to restore blood flow.

Currently, synthetic vascular grafts made using expanded polytetrafluoroethylene (ePTFE) or Dacron are commercially available as treatments to cardiovascular diseases. (uwaterloo.ca)
These synthetic vascular grafts have good patency, which is a measure used to determine the success of the grafts, and are actively used in more than 400,000 life-saving procedures in the United States alone. (uwaterloo.ca)
However, the available synthetic grafts have limitations - their patency is poor when used in small-diameter application. (uwaterloo.ca)
Polyurethane vascular grafts were modified with gelatin and collagen to enhance endothelial cell adhesion and were modified using heparin to reduce thrombogenesis. (uwaterloo.ca)
Likewise, poly(vinyl alcohol) (PVA) vascular grafts were developed in 2008. (uwaterloo.ca)
In this thesis, the roles crosslinking density and interlayer adhesion play in compliance and burst pressure of PVA vascular grafts were studied. (uwaterloo.ca)

Although effective in restoring the blood flow, these procedures activate a population of vascular cells resident in the arterial wall to grow into the vesslel lumen, causing re-narrowing (restenosis) of the treated artery months or years later. (ca.gov)
Once activated, these cells grow and differentiate into cells that invade the vascular luman and contribute to arterial re-narrowing. (ca.gov)

However, if signs of a low systemic cardiac output develop (low urine output and progressive acidosis) it will be necessary to increase the pulmonary vascular resistance by active respiratory management: it may seem counterintuitive to reduce inspired oxygen in a sick, shocked neonate but this is frequently necessary to achieve stability.
