Surgical transluminal iliac angioplasty with selective stenting: long-term results assessed by means of duplex scanning. (1/1972)

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)

Plaque area increase and vascular remodeling contribute to lumen area change after percutaneous transluminal angioplasty of the femoropopliteal artery: an intravascular ultrasound study. (2/1972)

OBJECTIVE: The aim of the study was to assess the change in lumen area (LA), plaque area (PLA), and vessel area (VA) after percutaneous transluminal angioplasty (PTA) of the femoropopliteal artery. METHODS: This was a prospective study. Twenty patients were studied with intravascular ultrasound (IVUS) immediately after PTA and at follow-up examination. Multiple corresponding IVUS cross-sections were analyzed at the segments that were dilated by PTA (ie, treated sites; n = 168), including the most stenotic site (n = 20) and the nondilated segments (ie, reference sites; n = 77). RESULTS: At follow-up examination, both the PLA increase (13%) and the VA decrease (9%) resulted in a significant LA decrease (43%) at the most stenotic sites (P =.001). At the treated sites, the LA decrease (15%) was smaller and was caused by the PLA increase (15%). At the reference sites, the PLA increase (15%) and the VA increase (6%) resulted in a slight LA decrease (3%). An analysis of the IVUS cross-sections that were grouped according to LA change (difference >/=10%) revealed a similar PLA increase in all the groups: the type of vascular remodeling (VA decrease, no change, or increase) determined the LA change. At the treated sites, the LA change and the VA change correlated closely (r = 0.77, P <.001). At the treated sites, significantly more PLA increase was seen in the IVUS cross-sections that showed hard lesion or media rupture (P <.05). No relationship was found between the presence of dissection and the quantitative changes. CONCLUSION: At the most stenotic sites, lumen narrowing was caused by plaque increase and vessel shrinkage. Both the treated sites and the reference sites showed a significant PLA increase: the type of vascular remodeling determined the LA change at follow-up examination. The extent of the PLA increase was significantly larger in the IVUS cross-sections that showed hard lesion or media rupture.  (+info)

Intraoperative transoesophageal echocardiography as an adjuvant to fluoroscopy during endovascular thoracic aortic repair. (3/1972)

OBJECTIVES: To define the utility of intraoperative transeophageal echocardiography (TEE) during endovascular thoracic aortic repair. DESIGN: Retrospective study. MATERIALS: Five patients underwent six transluminal endovascular stent-graft procedures for repair of thoracic aortic disease. METHODS: After induction of anaesthesia, a multiplane or biplane TEE probe was placed to obtain views of the diseased aorta. Both transverse and longitudinal planes of the aortic arch and descending thoracic aortic segments were imaged. The aortic pathology was confirmed by TEE and the proximal and distal extents of the intrathoracic lesion were defined. Doppler and colour-flow imaging was used to identify flow patterns through the aorta before and after stent-graft deployment. RESULTS: Visualisation and confirmation of the aortic pathology by ultrasonography was accomplished in all patients. TEE was able to confirm proper placement of the endograft relative to the aortic lesion after deployment and was able to confirm exclusion of blood flow into the aneurysm sacs. CONCLUSIONS: TEE may facilitate repair by confirming aortic pathology, identifying endograft placement, assessment of the adequacy of aneurysm sack isolation, as well as dynamic intraoperative cardiac assessment.  (+info)

Effect and outcome of balloon angioplasty and stenting of the iliac arteries evaluated by intravascular ultrasound. (4/1972)

OBJECTIVES: To document the mechanism of percutaneous transluminal angioplasty (PTA) and stenting of the iliac arteries, and to relate the effect to patency. MATERIALS AND METHODS: Thirty-seven stenotic iliac arteries were examined by intravascular ultrasound (IVUS) and arteriography before and after PTA, and after stent deployment (n = 16). The patients were followed prospectively by duplex scanning at 3, 6, 12, 18 and 24 months after the intervention. RESULTS: The effect of PTA was established by both compression and stretching with the major contribution arising from stretching. There were differences in the effect of PTA dependent on plaque morphology: in homogeneous eccentric lesions, stretching contributed significantly more than compression to the luminal gain, while stretching and compression contributed equally in concentric or heterogeneous plaques. Stenting of the arteries had no effect on the free luminal area as measured by IVUS. The primary 1-year patency rate was 72%. The patency was related to the free luminal area and diameter and the heterogenicity of the plaque as evaluated by IVUS. The arteriographic measurements did not have any predictive value. CONCLUSION: IVUS was able to document the effect of PTA and stenting in the iliac arteries, and predict the outcome. The luminal gain and reduction in degree of stenosis seemed to be accomplished primarily by stretching of the arteries and to a lesser extent by plaque compression. Stenting did not change the IVUS measurements. Patency was related to the size of the free lumen and the heterogenicity of the plaque.  (+info)

Antegrade visceral revascularisation via a thoracoabdominal approach for chronic mesenteric ischaemia. (5/1972)

OBJECTIVES: It has been suggested that patients with chronic visceral ischaemia are elderly and emaciated hence they may not tolerate antegrade visceral revascularisation via a thoracoabdominal approach. There are no studies to support this assumption. The purpose of this study is to assess the efficacy of this approach for the treatment of chronic visceral ischaemia. METHODS: Between 1988 and 1996, 10 patients underwent antegrade visceral revascularisation for chronic visceral ischaemia via a thoracoabdominal approach and were followed-up for a mean of 40 months. Eight patients were treated with aorto superior mesenteric artery bypass and implantation of the coeliac axis in the graft and two patients with aorto superior mesenteric bypass alone. Graft patency was monitored with duplex scanning. RESULTS: There were no postoperative deaths in this series. Two patients developed postoperative pulmonary infections and required intubation for a short period of time. All patients were discharged after a mean of 17 days (range 7-38). Follow up with duplex scanning revealed that all grafts were patent. One patient developed a high grade anastomotic stenosis which was followed by recurrence of the symptoms. This was dilated on three occasions by balloon angioplasty within a period of 17 months. On the last occasion a stent was placed and since the patient remains asymptomatic. CONCLUSIONS: Antegrade visceral revascularisation via a thoracoabdominal approach is a durable and effective method of relieving symptoms of chronic visceral ischaemia. The low morbidity in this series justifies larger studies in order to establish the true incidence of complications.  (+info)

Outcome of the first 100 femoropopliteal angioplasties performed in the operating theatre. (6/1972)

OBJECTIVES: To examine the factors influencing outcome and restenosis in an initial series of 100 infrainguinal angioplasties. DESIGN: Prospective study of angioplasties of the superficial femoral and popliteal arteries performed over a 42-month period. MATERIALS AND METHODS: One hundred consecutive angioplasties in 96 patients performed in the operating theatre between January 1993 and June 1996 were followed prospectively with clinical, ABI, and duplex assessment. Forty-four procedures were for disabling claudication and 56 for critical ischaemia. Stents were deployed in 30 limbs. RESULTS: Angioplasty was successful in 84 of 100 limbs. Cumulative patency of the entire group at 3, 6, 12 and 18 months was 78%, 60%, 53%, and 49% respectively, while excluding initial failures, gave patencies of 95%, 69%, 63%, and 58%, respectively. Claudicants with a 1-year patency of 64% did significantly better than patients with critical ischaemia (44% p < 0.05). Angioplasties performed during the initial 21 months had a 1-year patency of 42%, while those performed in the final 21 months had a 74% patency (p = N.S.). The patency for stented arteries was 66% vs. 49% for angioplasty alone (p = N.S.). The 2-year limb salvage rate was 91% in patents with critical ischaemia. Forty-six per cent of restenoses were asymptomatic. CONCLUSIONS: The results suggest that while angioplasty is useful in treating infrainguinal arterial disease, there is a learning curve, resulting in a high restenosis rate for occlusive and multilevel disease, while concomitant placement of stents may be beneficial.  (+info)

Managing Budd-Chiari syndrome: a retrospective review of percutaneous hepatic vein angioplasty and surgical shunting. (7/1972)

BACKGROUND: The role of percutaneous hepatic vein angioplasty in the management of Budd-Chiari syndrome has not been well defined. Over a 10 year period at our unit, we have often used this technique in cases of short length hepatic vein stenosis or occlusion, reserving surgical mesocaval shunting for cases of diffuse hepatic vein occlusion or failed angioplasty. AIMS: To review the outcome of angioplasty and surgical shunting to define their respective roles. PATIENTS: All patients treated by angioplasty or surgical shunting for non-malignant hepatic vein obstruction over a ten year period from 1987 to 1996. METHODS: A case note review of pretreatment features and clinical outcome. RESULTS: Angioplasty was attempted in 21 patients with patent hepatic vein branches and was successful in 18; in three patients treatment was unsuccessful and these patients had surgical shunts. Fifteen patients were treated by surgical shunting only. Mortality according to definitive treatment was 3/18 following angioplasty and 8/18 following surgery; in most cases this reflected high risk status prior to treatment. Venous or shunt reocclusion rates were similar for both groups and were associated with subtherapeutic warfarin in half of these cases. Most surviving patients in both groups are asymptomatic although one surgical patient has chronic hepatic encephalopathy. CONCLUSION: With appropriate case selection, many patients with Budd-Chiari syndrome caused by short length hepatic vein stenosis or occlusion may be managed successfully by angioplasty alone. Medium term outcome is good following this procedure provided that anticoagulation is maintained. Further follow up is required to assess for definitive benefits but we suggest that this should be included as a valid initial approach in the algorithm for management of Budd-Chiari syndrome.  (+info)

Follow-up results of transvenous occlusion of patent ductus arteriosus with the buttoned device. (8/1972)

OBJECTIVES: The purpose of this presentation is to document results of buttoned device (BD) occlusion of patent ductus arteriosus (PDA) in a large number of patients with particular emphasis on long-term follow-up in an attempt to provide evidence for feasibility, safety and effectiveness of this method of PDA closure. BACKGROUND: Immediate and short-term results of BD occlusion of PDA have been documented in a limited number of children. METHODS: During a six-year period ending August 1996, transcatheter BD closure of PDA was attempted in 284 patients, ages 0.3 to 92 years (median 7) under a protocol approved by the local institutional review boards and FDA with an investigational device exemption in U.S. cases. RESULTS: The PDAs measured 1 to 15 mm (median 4) at the narrowest diameter; 20 were larger than 8 mm and 10 larger than 10 mm. They were occluded with devices measuring from 15 to 35 mm delivered via 7F (N = 140) or 8F (N = 144) sheaths. Successful implantation of the device was accomplished in 278 (98%) of 284 patients. The Qp:Qs decreased from 1.8+/-0.6 (mean+/-SD) to 1.09+/-0.19 (p < 0.001). Effective occlusion defined as no (N = 167 [60%]) or trivial (N = 79 [28%]) residual shunt was achieved in 246 (88%) patients. All types of PDAs, irrespective of the shape (conical, tubular or short), size (small or large) or length (short or long) of the PDA and previously implanted Rashkind devices, could be occluded. Follow-up data, 1 to 60 months (median 24) after device implantation, were available in 234 (84%) patients. Seven (3%) patients required reintervention to treat residual shunt with (N = 2) or without (N = 5) hemolysis. Actuarial reintervention-free rates were 95% at 1 and 5 years. There was gradual reduction of actuarial residual shunts and were 40%, 28%, 21%, 14%, 11%, 10%, 6% and 0% respectively at 1 day, 1, 6, 12, 24, 36, 48 and 60 months after device implantation. Incorporation of folding plug over the button loop in 10 additional patients produced immediate and complete occlusion of PDA. CONCLUSIONS: This large multiinstitutional experience confirms the feasibility, safety and effectiveness of buttoned device closure of PDAs. All types of PDAs irrespective of the shape, length and diameter can be effectively occluded. Incorporation of folding plug over the button loop produces complete PDA occlusion at the time of device implantation.  (+info)

To determine whether balloon angioplasty can provoke arterial vasoconstriction independent of platelet aggregation and neurogenic input, we studied the spontaneous vasomotor effects of balloon dilatation in isolated, perfused whole-vessel segments of rabbit aorta and pig carotid artery. Freshly dissected rabbit thoracic aortas were mounted in a muscle bath-perfusion chamber, perfused with physiologic saline solution at 70 mm Hg, and allowed to equilibrate. The proximal or distal half of the aortas were dilated with either a large (5 mm, 31-51% stretch beyond relaxed diameter) or a small (4 mm, 5-16% stretch) balloon angioplasty catheter with the other half of the vessel serving as the control. A similar series of experiments were performed in pig carotid arteries using large (6 or 8 mm, 48-90% stretch) balloon catheters. The spontaneous vasomotor effects of balloon angioplasty were examined with long-axis, high-frequency ultrasonic imaging combined with computerized edge detection image ...

A balloon angioplasty catheter having a balloon head assembly carried at the distal end of an elongated catheter body. The balloon head assembly includes an inflatable balloon envelope and a perfusion lumen extending through the balloon envelope to provide a blood flow passage during inflation of the balloon envelope. In a preferred embodiment, the perfusion lumen is formed by a helical member having spaced coils encapsulated with a flexible material. A discharge lumen is formed by a projecting tip, the tip being integrally formed with the balloon envelope. Discharge orifices are provided through the tip sidewall. In a preferred embodiment, the side discharge orifices are elongated in the general direction of perfusion flow through the balloon head. The invention also encompasses means for facilitating discharge of perfused blood through the discharge orifices. This is accomplished by valving perfusate flow through the discharge lumen.
Technical success was 85% and 100% in balloon angioplasty and stent insertion, respectively. Clinical success was achieved in 78% of balloon angioplasties and in 100% of stent insertions. At 1, 5, and 10 years after balloon angioplasty, patency rates were 87%, 82%, and 68% respectively, and the rates of stent patency were all 100%. Portal vein size measured during the operation of patients with and without recurrence were 19±4.2 mm and 19±3.0 mm (P = 0.956), respectively.

In our series the repeat revascularisation rate for restenosis was similar in dialysis and non-dialysis patients. This suggests that dialysis does not affect the clinical restenosis rate when coronary stenting is performed, or when a stent-like result is obtained after balloon angioplasty. The rate was half that reported previously, which has ranged from 47-81%.9-15 In the study by Schoebel and colleagues,5 the six month clinical restenosis rate was 65% in dialysis patients, compared with 37 (9)% following balloon angioplasty (v 21 (10)% in our study). This suggests that residual stenosis is the main predictive factor of restenosis after PTCA, in accordance with previous studies.21-23 In our study dialysis patients with stent-like results had the same clinical restenosis rate as dialysis patients with coronary stenting. However, owing to the small number of patients, this needs to be confirmed in a larger prospective study. In the Benestent II study (second Belgium-Netherlands stent study), ...

Renal artery stenosis (RAS) caused by atherosclerotic changes of the renal arteries has become a concern as a cause of end-stage renal failure. Percutaneous balloon angioplasty with or without endovascular stenting is an increasingly accepted procedure at the expense of classical approaches such as aortorenal bypass and other types of surgery. Renal percutaneous transluminal angioplasty and stenting (RPTAS) represent the first therapeutic choice; however, there is doubt regarding the satisfactory long-term outcome for primary RPTAS. Currently, there is no clear evidence whether or not RPTAS prevents further progressive renal function decline because comparisons between interventional randomized studies and medical therapy are still lacking. Despite the fact that the use of angiotensin-converting enzyme inhibitors (ACEIs) may be a potential cause of acute renal failure, clinical data suggest that ACEI therapy is associated with better survival in patient with RAS. In our case, the use of ACEIs ...

Angioplasty, also known as balloon angioplasty and percutaneous transluminal angioplasty (PTA), is a minimally invasive, endovascular procedure to widen narrowed or obstructed arteries or veins, typically to treat arterial atherosclerosis. A deflated balloon attached to a catheter (a balloon catheter) is passed over a guide-wire into the narrowed vessel and then inflated to a fixed size. The balloon forces expansion of the blood vessel and the surrounding muscular wall, allowing an improved blood flow. A stent may be inserted at the time of ballooning to ensure the vessel remains open, and the balloon is then deflated and withdrawn. Angioplasty has come to include all manner of vascular interventions that are typically performed percutaneously. The word is composed of the combining forms of the Greek words ἀγγεῖον angeîon vessel or cavity (of the human body) and πλάσσω plássō form or mould. A coronary angioplasty is a therapeutic procedure to treat the stenotic ...
PCB has been used for BMS-ISR because previous studies have shown that PCB angioplasty is safe and effective in treating BMS-ISR (1). Although PCB is now widely used, there are few reports on intracoronary imaging of the drug-coated neointima after PCB angioplasty. In the current report, slow-flow phenomenon after PCB angioplasty was observed, and OCT and CAS nicely revealed drug-coated neointimal plaque after PCB angioplasty. To our knowledge, this is the first report of the case that slow-flow phenomenon occurred after PCB angioplasty and drug-coated neointimal plaque was evaluated by OCT and CAS. It was reported that PCB angioplasty was associated with diminished endothelial-dependent vasomotor function (2) and acute decrease in coronary flow reserve (3). In these cases, the slow-flow phenomenon after PCB angioplasty was partly caused by an impaired microvascular response as a result of drugs. In addition, CAS revealed white granular materials that might indicate undissolved drugs on the ...

The variable distention angioplasty balloon assembly, for insertion into a blood vessel, comprises an inner elongated, inflatable balloon having a distal portion, a proximal portion and an intermediate portion therebetween and defining therein a first chamber. The inner balloon has a first Youngs modulus. The outer elongated, inflatable balloon has a distal portion, a proximal portion and an intermediate portion therebetween positioned around the inner balloon and defines between the balloons a second chamber. The outer balloon has a second Youngs modulus. The inner balloon is substantially enclosed by the outer balloon, and the first Youngs modulus of the inner balloon is less than the second Youngs modulus of the outer balloon. The first chamber of the inner balloon and the second chamber of the outer balloon define a variable dilation structure for dilating an anatomical stricture. The dilation structure with variable characteristics has a first diameter and pressure characteristic curve defined

At the time of the initial reporting of results from NASCET and ECST, the first large multicenter randomized clinical trial comparing an endovascular approach to CEA for symptomatic patients with carotid stenosis was also initiated. In the CAVATAS (Carotid and Vertebral Artery Transluminal Angioplasty Study), 504 patients were randomized to carotid balloon angioplasty (with 26% stent use) versus CEA. The risk of death and ipsilateral stroke at 30 days and 3 years was comparable between the 2 strategies, with a higher risk of cranial nerve palsy (8.7% CEA vs. 0% angioplasty, p , 0.0001) but lower risk of restenosis at 1 year (4% CEA vs. 14% angioplasty, p , 0.001) with CEA (29). Despite the lack of randomized controlled trial data demonstrating the superiority of carotid stenting over balloon angioplasty in reducing restenosis, carotid stenting was increasingly undertaken, as it enabled the treatment of arterial dissections and addressed immediate elastic recoil after balloon angioplasty. ...

The data confirmed the indications from previous study results at one, two and three years in terms of:. Primary patency: Patients treated with Zilver PTX demonstrated 75% primary patency in the superficial femoral artery. This compares to 57.9% patency for patients with provisional bare metal stent placement in the study.. Restenosis reduction: Four-year restenosis was reduced by 41% with the paclitaxel coating in the head-to-head comparison of provisional paclitaxel-eluting stent placement vs. bare metal stent placement.. Revascularisation rate: 83.2% of patients with femoropopliteal lesions who were treated with Zilver PTX did not require revascularisation after four years. In comparison, 69.4% of patients treated with acutely successful percutaneous transluminal angioplasty or provisional bare metal stent placement did not require revascularisation.. ...
According to his study-Stent graft vs. balloon angioplasty for failing dialysis-access grafts- published in the New England Journal of Medicine, anatomic success with the stent graft compared to percutaneous transluminal angioplasty was 94% and 73% respectively. At six months, Haskal explained, binary restenosis was 27.63% for the stent graft and 77.61% for angioplasty.. He also noted that the 12-month reintervention rate to maintain patency was 1.9% for the stent graft and 2.4% for angioplasty. The 12-month index of patency function was 5.3% for the stent graft and 4.4% for angioplasty, for access circuit primary patency it was 24.1% and 10.3%, and for treatment area primary patency it was 4.7% and 24.8% respectively. The latter was statistically significant (p,0.001).. Results of the study exceeded our expectations, and that is a boon for dialysis patients, said Haskal. Dialysis is very demanding, and anything that prevents access sites from failing and reduces the need for invasive ...

Balloon angioplasty plays a major role in lower extremity revascularization and will likely be an essential technique in the foreseeable future. Drug-coated balloons have shown promise and will prompt renewed interest in the angioplasty mechanism and how it may be optimized (11-13). In arteries that are obstructed by atherosclerotic plaque, balloon angioplasty increases the vessel lumen diameter by causing dissection. Post-PTA dissections are uncontrolled arterial injuries that are usually manifested by longitudinal tears creating tissue flaps of varying degrees of severity that are visible angiographically. When post-PTA dissection produces a suboptimal result in current practice, the only reasonable option available is stent placement to secure the dissection flap and ensure the integrity of the lumen. Contemporary SFA stent trials conducted primarily in TASC A and B lesions have a stent bailout rate of 35% to 50% in patients randomized to balloon angioplasty (14,15). The more challenging ...

Background: The aim of this study was to investigate the efficacy and safety of paclitaxel-coated balloon (PCB) for the treatment of the bare-metal stent restenosis (BMS-ISR) and drug-eluting stent restenosis (DES-ISR).. Methods: This study was a prospective, multicenter, randomized (2:1) trial conducted in 208 patients with 213 in-stent restenosis lesions (BMS-ISR; 123 lesions, DES-ISR; 90 lesions) at 13 centers in Japan. Patients were randomly assigned to PCB group (PCB group, 137 patients with 142 lesions) or conventional balloon angioplasty group (BA group, 71 patients with 71 lesions). The primary endpoint was target vessel failure (TVF) at 6-month follow-up.. Results: Clinical and angiographic follow-up 6 months after intervention was performed in 207 patients (99.5%) with 208 lesions (97.7%). TVF was noted in 6.6% of PCB group and 31.0% of BA group (p,0.001). Recurrent restenosis occurred in 4.3% of PCB group and 31.9% of BA group (p,0.001).

BACKGROUND: This study is the third in a series of investigations on the requisite length of time that patients should be restricted to bed after coronary arteriography or percutaneous transluminal coronary angioplasty using a femoral artery approach. METHODS: A prospective, experimental-control group design with randomization was used initially to compare the incidence of bleeding between patients who remained in bed for 4 hours and patients who remained in bed for 6 hours after sheath removal following percutaneous transluminal coronary angioplasty. RESULTS: Rapid changes in the healthcare environment led to nurses collecting complete data sets for the experimental group only. The experimental group (n = 51) was 73% male and 27% female; mean age was 57 years (SD = 11.4 years). Mean time in bed was 4.1 hours (SD = 0.27 hours). Most patients (98%) did not bleed from the femoral artery access site after remaining in bed for 4 hours following sheath removal. Ninety-two percent of patients required ...
This procedure can greatly improve the blood flow through the coronary arteries and to the heart tissue in about 90% of patients and may eliminate the need for coronary artery bypass surgery. The outcome is relief from chest pain symptoms and an improved exercise capacity. In 2 out of 3 cases, the procedure is considered successful with complete elimination of the narrowing or blockage. This procedure treats the condition but does not eliminate the cause and recurrences happen in 1 out of 3 to 5 cases. Patients should consider diet, exercise, and stress reduction measures. If adequate widening of the narrowing is not accomplished, heart surgery (coronary artery bypass graft surgery, also called a CABG) may be recommended. ...
Laser balloon angioplasty (LBA) is a technique for improving the post angioplasty result by the radial diffusion of continuous wave Neodymium:YAG laser energy to the arterial wall during the final inflation of percutaneous transluminal coronary angioplasty (PTCA). Potential mechanisms of luminal improvement include sealing of dissections, reduction of arterial recoil, desiccation of thrombus, and reduction of thrombogenicity of tissues at the luminal surface. These effects are helpful in the management of failed PTCA as defined by the presence of a greater than 50% stenosis after conventional PTCA. Preliminary data suggest that LBA may be safe and effective for the treatment of abrupt closure, with a majority of patients successfully avoiding emergency coronary artery bypass surgery. Similarly, a cohort in which the residual post-PTCA luminal diameter was less than 50% of reference diameter (n=13) was subsequently treated with LBA and demonstrated uniform success in improving luminal diameter, ...

Definition : Thermal angioplasty catheters that use an electrical (e.g., radiofrequency) energy source to heat a metal cap or band; the cap typically encloses the distal tip of the catheter, while the metal band is placed around the catheter. They are used for thermal compression and ablation of the atheromatous plaque inside the vessels, except for heavily calcified plaque. These units do not deliver electric current to the tissues. Tip temperatures can exceed 400 degrees Celsius, allowing plaque to be vaporized, melted, or otherwise reformed. Electrically heated thermal angioplasty catheters are used mainly to open total occlusions or high-grade stenoses in peripheral arteries; they may also be used to facilitate balloon angioplasty, based on the assumption that thermal ablation improves clinical success and reduces the rate of complications and restenosis..

Restenosis is the recurrence of stenosis, a narrowing of a blood vessel, leading to restricted blood flow. Restenosis usually pertains to an artery or other large blood vessel that has become narrowed, received treatment to clear the blockage and subsequently become renarrowed. This is usually restenosis of an artery, or other blood vessel, or possibly a vessel within an organ. Restenosis is a common adverse event of endovascular procedures. Procedures frequently used to treat the vascular damage from atherosclerosis and related narrowing and renarrowing (restenosis) of blood vessels include vascular surgery, cardiac surgery, and angioplasty. When a stent is used and restenosis occurs, this is called in-stent restenosis or ISR. If it occurs following balloon angioplasty, this is called post-angioplasty restenosis or PARS. The diagnostic threshold for restenosis in both ISR or PARS is ≥50% stenosis. If restenosis occurs after a procedure, follow-up imaging is not the only way to initially ...

Angioplasty is a minimally invasive procedure that opens up a blocked artery or vein so blood can flow through it normally again. An interventional radiologist performs the procedure using an angiogram for guidance. Through angioplasty, the interventional radiologist opens the blockage by inserting a balloon-tipped catheter into the affected blood vessel. The balloon is then inflated to open the blockage. You may benefit from angioplasty if you: Have advanced atherosclerosis (buildup of plaque in your arteries) that isnt improving with lifestyle changes and medicines Have a high risk for heart attack, stroke or gangrene due to atherosclerosis Have persistent chest pain (angina) Have narrowing of a central vein, fistula or graft used for dialysis Had a heart attack and didnt undergo thrombolysis immediately afterwards What to Expect: Angioplasty Angioplasty can take a few hours to complete. The length of the procedure depends on the number of blocked blood vessels and location of the blood

Coronary artery restenosis after balloon angioplasty occurs in 30% to 50% of patients. More than 50 randomized trials have failed to show a successful pharmacologic intervention, and the first 2 trials with directional atherectomy (1, 2) produced equivocal results. In these 2 stent trials, the angiographic results were remarkably similar for both post-procedural and follow-up minimum luminal diameter and percent diameter stenosis. Each showed an absolute 10% reduction in angiographic restenosis with stenting, a significant advance in this field. The clinical outcome results can be interpreted in various ways. A more negative analysis than that presented by the authors can be summarized by tabulating the results for stenting rather than angioplasty in 100 patients. In the Benestent study, 10 patients were spared repeat angioplasty at a cost of 1 extra acute coronary artery closure, 2 more bypass operations, 10 extra bleeding or vascular complications, and 540 additional acute hospital days.

Your heart has been mended, but its not like before. About 45 million people in India suffer from coronary artery disease each year, most of them in the age bracket of early forties to late seventies. Tiny blood vessels supplying the heart and providing it with nutrition either thicken or get clogged up with clots and fatty deposits, slowly diminishing in their capacity to function properly.. Angioplasty or percutaneous transluminal coronary angioplasty (PTCA) is a temporary technique used to widen the coronary arteries by placing a stent (a small, expandable tube) in the area of blocked vessel to enable blood circulation to the heart.. The word angioplasty is derived from Greek words angio meaning vessel and plasticos meaning fit for moulding. The rate of performing angioplasty surgeries in India has increased by about 42% in 2015. This is indeed a dismal situation where people are increasingly seeking treatment for a condition whose origins are based in our faulty lifestyles.. Unhealthy ...
Patients are wildly enthusiastic about these treatments. Thereve been focus groups with prospective patients who have stunningly exaggerated expectations of efficacy. Some believed that angioplasty would extend their life expectancy by 10 years! Angioplasty can save the lives of heart-attack patients. But for patients with stable coronary disease, who comprise a large share of angioplasty patients? It has not been shown to extend life expectancy by a day, let alone 10 years-and its done a million times a year in this country. Jones adds wryly, If anyone does come up with a treatment that can extend anyones life expectancy by 10 years, let me know where I can invest ...
BACKGROUND: Total occlusion of the infrarenal abdominal aorta is a very rare disease in clinical practice. The clinical outcome may be poor unless management is attempted promptly. Surgical bypass has been recommended as the treatment of choice for these lesions. However, there was relatively high surgical mortality and morbidity associad with aorto-bifemoral bypass graft in patients with other systemic disease, especially coronary artery disease. As a result, the use of, thrombolysis with percutaneous transluminal angioplasty (PTA) has recently been extended to this disease as an alternative method to surgery. PTA is technically simpler with less morbidity and mortality than surgery.We report our experience with thrombolysis and balloon angioplasty of total aortic occlusion in 14 patients between March 1991 and December 1996. METHODS: Fourteen patients, whose mean age was 59+/-13 years (11 male, 3 female), serve as the studys patients. Aortography was introduced via transbrachial artery. The ...
Evidence-based recommendations endovascular stent insertion for treating intracranial atherosclerotic disease (ICAD/intracranial stenosis)
Objective:To summarize our experience of treating lower extremity arteriosclerosis obliterans (ASO) by endovascular angioplasty combined with traditional operation.Methods:From November 2003 to Jaunary 2006,16 cases of lower extremity ASO with multi-segment lesions underwent bypass vessel transplantation in combination with balloon angioplasty and/or stent implantation.All patients except one (peri-surgical death) had followed-up for 2~26 months. Results: The symptoms were markedly improved due to collateral circulation formation after treatment in 14 patients.There were recurrence of artery obliteration (n=2),obliteration of artificial vessel (n=1) and stricture of stent (n=1).Conclusion:Endovascular angioplasty combined with traditional surgical operation can significantly improve the success rate of surgical procedure,reduce the difficulty and complexity of surgery and surgical complications as well.
In 2007 it was reported that eight million Americans are affected by Peripheral Vascular Disease (PVD) and of these affected, around ten percent report being symptomatic (Mayo Clinic). With such a large percentage of Americans affected by this problem, many providers who care for these patients opt to treat with the least invasive option and then progress to more invasive means if necessary. To date, Percutaneous Transluminal Angioplasty (PTA) has been the preferred minimally invasive endovascular treatment option for symptomatic PVD. Though this option is preferred and used extensively, there are concerning short and long term potential consequence such as dissection and recoil of the arterial wall in the acute setting (Laird 2005), and, more importantly, re-stenosis of the affected area in the long term setting causing recurrent symptoms and the need for further treatment. There have been multiple reported results showing that the re-stenosis rates have been as high as 60% (Muradin 2001).
