Purpose: To assess the effectiveness and safety of self-expanding metallic stents as a primary palliative treatment for inoperable
malignant colorectal strictures.
Methods: Under radiological guidance 20 self-expanding metallic Wallstents were implanted in 16 consecutive patients with colorectal
stenoses caused by malignant neoplasms, when surgical treatment of the condition had been ruled out. The patients were followed
up clinically for 1–44 months, until death or termination of this study.
Results: The stents were successfully implanted in all cases and resolved the clinical obstruction in all the patients except one,
who underwent subsequent colostomy. During follow-up of the remaining 15 patients, clinical complications arising from the
procedure were pain (two patients), minor rectal bleeding (one patient), and severe rectal bleeding (one patient) (26%). There
were three cases of stent migration and three cases of stent occlusion, and reintervention by us was necessary in 20% of cases
(3/15). The mean life span following the procedure was 130 days, and none of the patients exhibited clinical symptoms of obstruction
at the time of death (12 patients) or termination of the study (3 patients).
Conclusion: Deployment of metallic stents under radiologic guidance is an effective alternative as a primary palliative measure in malignant
colorectal obstruction, though the possible clinical complications and need for repeat intervention during follow-up should
be taken into account. 相似文献

Purpose: The application of self-expanding metallic endoprostheses (stents) to treat symptomatic pelvic venous spurs as an alternative
to surgery.
Methods: Wallstents with a diameter from 14 to 16 mm and one Cragg stent were placed in the left common iliac vein of eight patients
(seven women, one man; mean age 42 years) with a symptomatic pelvic venous spur (left deep venous thrombosis or post-thrombotic
leg swelling). Four patients had surgical thrombectomy prior to stent placement.
Results: Technical success with immediate reduction of left leg circumference was achieved in all eight patients. A primary patency
rate of 100% was observed during an average follow-up of 3 years (range 10–121 months). There were no procedural or stent-related
complications.
Conclusion: The percutaneous transfemoral placement of self-expanding metallic stents is an effective minimally invasive alternative
to surgery in the treatment of symptomatic pelvic venous spur.

Gastric and Duodenal Stents: Follow-Up and Complications 总被引:11,自引:0,他引:11
Isabel Teresa Pinto Pabón Laura Paúl Díaz Juan Carlos Ruiz de Adana Julio López Herrero 《Cardiovascular and interventional radiology》2001,24(3):147-153
Purpose: To assess the efficacy of self-expanding metallic stents in treating inoperable gastric and duodenal stenoses during follow-up
and to evaluate the complications encountered.
Methods: A total of 31 patients suffering from gastroduodenal obstruction (29 malignant, 2 benign) were treated with a self-expanding
metallic stent (Wallstent). In 24 cases insertion was by the peroral route, in seven cases via gastrostomy.
Results: All the strictures were successfully negotiated under fluoroscopic guidance without having to resort to endoscopy. A total
of 27 patients (87%) were able to resume a regular diet, a soft diet, or a liquid diet orally. Complications included one
case of stent malpositioning, one case of leakage of ascitic fluid through the gastrostomy orifice, one case of perforation
and fistula to the biliary tree, and two cases of hematemesis. In two patients (6%) additional stents were implanted to improve
patency. In all patients follow-up was maintained until death. Recurrence of symptoms immediately before death occurred in
seven cases (23%). Mean survival time of patients was 13.3 weeks (SE ± 4.6).
Conclusions: The deployment of gastroduodenal stents resulted in good palliation of inoperable gastric and duodenal stenoses. Certain
technical aspects, e.g., adaptation of stents to bowel morphology, is critical to proper stent function and avoidance of complications. 相似文献

Clinical Experience with Covered Wallstents for Biliary Malignancies: 23-Month Follow-Up 总被引:4,自引:4,他引:0
Plinio Rossi Mario Bezzi Filippo M. Salvatori Claudio Panzetti Michele Rossi Gianluca Pavia 《Cardiovascular and interventional radiology》1997,20(6):441-447
Purpose: To evaluate the effectiveness of partially covered metallic Wallstents to prevent tumoral ingrowth in patients with neoplastic
obstruction of the biliary tract.
Methods: Twenty-one patients with malignant obstructive jaundice have been treated with Wallstents partially covered with a polyurethane
polymer. In total, 36 covered stents (8 and 10 mm in diameter, 70 and 90 mm long) were deployed. All the stents were free
from covering at both ends.
Results: Jaundice was successfully treated in 100% of cases. There were no problems related to the releasing system during stent positioning,
no major complications, and no incompatibility reactions to the materials composing the endoprostheses. At 23-month follow-up,
6 patients are still alive and 15 are dead; of these 15 patients, 11 died in the first 6 months and the last 4 died between
6 and 23 months. Seven patients had an obstructed stent; in four of these, cholangioscopy showed the presence of tumoral ingrowth
and in one it showed necrotic tissue with biliary pigments and inflammatory cells. No biopsy specimen was obtained in the
remaining two patients with stent obstruction. The follow-up, ranging from 7 to 23 months, showed a primary patency of 46.8%
and 24.6% and an assisted patency of 66.3% and 59% at 6 months and 23 months, respectively.
Conclusions: Covered metallic stents are effective and may produce improved survival in patients with malignant biliary obstruction (27.8%
at 23 months). Stent patency, however, is similar to that of uncovered stents. Modifications in the design of the covering
membrane may reduce stent obstruction resulting from disruption of the plastic covering.

Treatment of Complete and Partial Obstruction of the Nasolacrimal System with Polyurethane Stents: Initial Experience 总被引:2,自引:0,他引:2
Juan M. Pulido-Duque Ricardo Reyes José M. Carreira Francisco Vega Elias Górriz M. Dolores Pardo Francisco Perez Manuel Maynar 《Cardiovascular and interventional radiology》1998,21(1):41-44
Purpose: To present our experience in the treatment of nasolacrimal occlusion by means of polyurethane stents.
Methods: Forty polyurethane stents were placed under fluoroscopic guidance in 35 consecutive patients with epiphora due to total or
partial obstruction of the nasolacrimal system. The set designed by Song was used in all patients. The procedure was performed
by introducing a guidewire through the superior punctum into the canaliculus and advancing it across the obstruction into
the inferior meatus of the nasal cavity. After pulling out the guidewire, the stent was advanced in retrograde fashion and
released into the sac and the nasolacrimal duct.
Results: The technical success rate was 100%. The average time for the procedure was 25 min (range 10–60 min). Immediate complications
were: mild pain (n= 5), severe pain (n= 1), minimal epistaxis (n= 7), and moderate epistaxis (n= 1). No major complications occurred. The last clinical control revealed complete resolution of epiphora in 35 eyes and partial
resolution in four; one patient did not improve.
Conclusion: This technique for treatment of obstruction of the nasolacrimal system is simple and safe, and may obviate the use of more
invasive procedures.

Venous recanalization by metallic stents after failure of balloon angioplasty or surgery: Four-year experience 总被引:2,自引:0,他引:2
Gwen K. Nazarian M.D. William R. Austin Scott A. Wegryn Haraldur Bjarnason Daniel J. Stackhouse Wilfrido R. Castañeda-Zúñiga David W. Hunter 《Cardiovascular and interventional radiology》1996,19(4):227-233
Purpose: This retrospective study describes our updated experience in treating venous stenoses and occlusions with metallic endovascular
stents.
Methods: Gianturco, Palmaz, and Wallstent stents were placed in 55 patients over a 4-year period. Stent sites included the subclavian
veins (9), innominate veins (3), superior vena cava (4), inferior vena cava (3), iliac veins (29), femoral veins (5), and
portal veins (6). The most common indications for stent placement were malignant stenoses and chronic pelvic venous occlusions.
Venoplasty and/or urokinase were used as ancillary therapy. Patients were anticoagulated for 3–6 months. Follow-up included
clinical assessment and duplex ultrasound.
Results: Lifetable analysis shows 59%, 63%, and 72% primary, primary assisted, and secondary 1-year patency rates, respectively. The
4-year primary patency rates were the same. Duration of patency depended on the venous site. Death was a complication of stent
placement in 2 patients and 12 patients died within 6 months after stent placement from primary disease progression. Although
early failures were more common in stents placed across occlusions than stenoses, 1-year secondary patency rates were comparable.
Primary patency rates were only slightly lower in patients with malignant obstruction than in patients with benign disease.
Conclusion: Endovascular stent placement provides a nonsurgical alternative for reestablishment of venous flow and symptomatic relief
in patients with benign as well as malignant venous obstruction.

Purpose: Gastric outlet obstruction is a debilitating complication of upper gastrointestinal malignancy. We present our experience
with insertion of self-expanding metal stents (SEMS).
Methods: Twenty-eight patients were referred, stenting being attempted in 23. Two patients had esophageal Wallstents inserted through
a gastrostomy; 21 had an endoscopic approach with enteral Wallstents.
Results: One stent insertion failed, ten patients (45%) returned to a normal diet, ten patients (45%) managed semi-solid food and
two patients (9%) had no significant improvement. No immediate complications were seen. One patient subsequently developed
pancreatitis. Reintervention (4 stents, 1 jejunostomy, 1 gastrojejunostomy) was required in six of 22 patients (27%) for inadequate
stent expansion (1), second stricture (2), stent migration (1), and tumor ingrowth (2). The mean survival was 95.4 days (SD
78.8 days, range 3–230 days). The mean follow-up time was 98.9 days (SD 86.7 days, range 3–309 days).
Conclusions: SEMS are effective in palliating malignant gastric outlet obstruction. A combined endoscopic/fluoroscopic approach allows
the most complete assessment of the stricture and removes the need for gastrostomy insertion. Careful assessment of the gastrointestinal
tract distal to the lesion is important. 相似文献

We assessed the results of self-expanding metallic stent insertion into benign proximal tracheal stenosis in patients not appropriate or unfit for surgical repair. Proximal benign tracheal stenoses had occurred in 11 patients (7 men, 4 women, mean age 68.8 years) after long-time intubation (n = 6), tracheostomy (n = 4), or chondropathia (n = 1). Fourteen self-expanding nitinol stents were placed in the patients under general anesthesia with endoscopical and fluoroscopical guidance. Stent insertion was successful in all cases and led to immediate relief of the morphological and functional airway obstruction. No immediate complications were noted. During the mean follow-up period of 67.5 weeks we observed one recurrent dyspnea 3 months after implantation and granuloma formation at the stent insertion site in another patient. Both complications were successfully treated with additional stent insertion in one case and laser resection of granulomas in the other. Self-expanding nitinol stents should be considered for the treatment of benign proximal tracheal obstruction in selected patients for whom surgical repair is contraindicated. 相似文献

Efficacy and complications of the gianturco-Z tracheobronchial stent for malignant airway stenosis 总被引:1,自引:0,他引:1
Yasuo Nakajima Yasuyuki Kurihara Hiroshi Niimi Shoko Konno Tohru Ishikawa Hiroaki Osada Hiroshi Kojima 《Cardiovascular and interventional radiology》1999,22(4):287-292
Purpose: To describe our experience using the Gianturco Z-stent (G-Z stent) for the management of malignant tracheobronchial stenosis,
with special reference to complications.
Methods: Thirty-six stents were used in 22 patients with 28 lesions. Thirteen patients were grade 5 according to the Hugh-Jones classification.
The technical success rates, follow-up results, and complications were reviewed on the basis of the patients' charts and radiographs.
Results: All stents were successfully placed in the ideal position without procedure-related complications. After the procedure, respiratory
status improved in 95% (21/22) of patients, and performance status improved in 77% (17/22). Mean survival after stent placement
was 15 weeks. Four patients suffered from increased thick secretions requiring multiple suctioning and aspiration by bronchoscopy.
One of these patients died from asphyxiation 2 weeks after placement. Stent disruption and/or migration was observed in six
patients. Of these six, four experienced life-threatening hemoptysis; all four had received aggressive anticancer treatment.
Conclusion: G-Z stents are useful for palliation of malignant tracheobronchial obstruction. However, complications of stent strut fracture
and migration give cause for concern. 相似文献

Are Covered Stents Really Effective at Closing Esophagotracheal Fistulas? Results of an Animal Study 总被引:2,自引:0,他引:2
Wagner HJ Stinner B Barth P Klose KJ 《Cardiovascular and interventional radiology》2000,23(4):291-297
Purpose: To determine whether covered self-expanding metal stents successfully exclude experimentally created esophagotracheal fistulas.
Methods: Esophagotracheal fistulas were surgically created in the upper third of the esophagus in 12 minipigs and immediately sealed
by implantation of a covered self-expanding metal stent (20 mm expanded diameter) in the esophagus. Before the animals were
killed, after 3, 7, 14, 28, 30, and 36 days, the position of the stent and the sealing of the fistula were monitored fluoroscopically.
The esophagus, trachea, and both lungs were examined histologically.
Results: Creation of an esophagotracheal fistula was successful in all cases. All fistulas were widely patent at autopsy. The technical
success rate for stent deployment and initial sealing of the fistula was 100%. During follow-up, five stents migrated distally,
but none into the stomach. Therefore, the fistula was no longer excluded in five animals. In seven animals the stent sealed
the fistula until the death of the animal. Tracheal narrowing necessitated additional tracheal stenting in three animals.
Two minipigs died due to aspiration of food. Histologic examination showed signs of aspiration in all animals with stents
in place for longer than 2 weeks.
Conclusion: This experimental animal study revealed worse results for sealing of esophagotracheal fistulas with covered self-expanding
metal stents than have been reported for the clinical use of these devices. 相似文献

Purpose: To evaluate the patency and healing characteristics of a woven polyester fabric-covered stent in the canine model.
Methods: Twenty-four self-expanding covered stents were placed in the infrarenal aorta and bilateral common iliac arteries of eight
dogs and evaluated at 1 (n = 2), 3 (n = 2), and 6 (n = 4) months. Stent assessment was done using angiography prior to euthanasia, and light and scanning electron microscopy.
Results: Angiographically, just prior to euthanasia, 8 of 8 aortic and 14 of 16 iliac endovascular covered stents were patent. Histologically,
the stented regions showed complete endothelialization 6 months after graft implantation. A neointima had formed inside the
stented vessel regions resulting in complete encasement of the fabric-covered stent by 3 months after graft implantation.
Medial compression with smooth muscle cell atrophy was present in all stented regions. Explanted stent wires, examined by
scanning electron microscopy, showed pitting but no cracks or breakage.
Conclusion: The covered stent demonstrated predictable healing and is effective in preventing stenosis in vessels 10.0 mm or greater
in diameter but does not completely preclude stenosis in vessels 6.0 mm or less in diameter. 相似文献

Purpose: The efficacy and safety of endovascular stent implantation to correct dissection or a suboptimal result after percutaneous
transluminal angioplasty (PTA) was evaluated in patients suffering from aortic stenosis due to aortoarteritis.
Methods: Twelve children and young adults [aged (mean ± SD) 18.2 ± 8.7 years] underwent stent implantation after PTA of the aorta,
seven for obstructive dissection, four for ineffective balloon dilatation, and one for recurrent restenosis. Nine patients
underwent implantation of self-expandable stents and three received balloon-expandable Palmaz stents.
Results: Stent implantation could be successfully performed in all 12 patients. After stent implantation, the peak systolic pressure
gradient decreased from 91 ± 33.5 mmHg to 12.4 ± 12.5 mmHg (p < 0.001). The diameter of the stenosed segment increased from 4.6 ± 0.8 mm to 11.1 ± 1.9 mm (p < 0.001). The dissection was completely covered in all seven patients with dissection. Except for epigastric pain with vomiting in
one patient, there was no complication. On follow-up, over 12–57 months (mean 26.8 ± 10.8 months), 11 patients (91.6%) had
marked improvement in their blood pressure. Patients with congestive heart failure and claudication also showed improvement.
Repeat catheterization in five patients, between 6–30 months (mean 16.8 ± 9.1 months) after stent implantation, showed sustained
improvement in four and a fusiform, long segment, intrastent restenosis after 30 months in one child. The stenosis was safely
redilated.
Conclusion: Endovascular aortic stent implantation is safe and provides good immediate relief in patients with unsatisfactory results
after balloon angioplasty. Improvement is sustained in most patients on intermediate-term follow-up. 相似文献

A self-expanding metallic stent (Wallstent) was used to relieve obstruction of the common bile duct in a young male with
a desmoplastic small cell tumor of the abdomen. Two months after insertion and following a course of chemotherapy the lower
end of the stent eroded the mucosa of the second part of the duodenum causing severe gastrointestinal hemorrhage which necessitated
laparotomy and trimming of the stent. This complication may have been due to shrinking of the tumor as well as thrombocytopenia
following chemotherapy.

Purpose: To evaluate the long-term mechanical behavior in vivo of expandable endobronchial wire stents, we imaged three different
prostheses in the treatment of tracheobronchial disease.
Methods: Six patients with bronchial stenoses (three benign, three malignant) underwent insertion of metallic stents. Two self-expandable
Wallstents, two balloon-expandable tantalum Strecker stents and two self-expandable nitinol Accuflex stents were used. Measurements
of deformation properties were performed during voluntary cough by means of fluoroscopy, at 1 month and 7–10 months after
implantation. The procedures were videotaped, their images digitized and the narrowing of stent diameters calculated at intervals
of 20 msec.
Results: After stent implantation all patients improved with respect to ventilatory function. Radial stent narrowing during cough
reached 53% (Wallstent), 59% (tantalum Strecker stent), and 52% (nitinol Accuflex stent) of the relaxed post-implantation
diameter. Stent compression was more marked in benign compared with malignant stenoses. In the long term permanent deformation
occurred with the tantalum Strecker stents; the other stents were unchanged.
Conclusion: Endobronchial wire stents can be helpful in the treatment of major airway collapse and obstructing bronchial lesions. However,
evidence of material fatigue as a possible effect of exposure to recurrent mechanical stress on the flexible mesh tube may
limit their long-term use. This seems to be predominantly important in benign bronchial collapse. 相似文献

Purpose: The treatment of inoperable tracheobronchial stenoses with Palmaz stents is analyzed in terms of the clinical effect, typical
complications, and long-term follow-up.
Methods: Twenty-seven Palmaz stents were placed in 22 patients with the help of a rigid bronchoscope.
Results: Stents were implanted in the distal trachea, the main bronchi, and the lower lobe bronchi. Twenty-one of 22 patients reported
an immediate subjective improvement in their respiratory situation. The mean survival time was 12 months; in two patients
the stents were well tolerated for up to 40 months. A redilation of three stents was successful up to 33 months. In three
cases a dislocation of the stent was observed; after bronchoscopic retraction a new stent was successfully implanted in each
case.
Conclusion: Treatment of inoperable tracheobronchial stenoses with the Palmaz stent is a safe procedure that provides an immediate improvement
of the patient's pulmonary situation. The Palmaz stent shows a minimal complication rate in the long-term follow-up. 相似文献

Purpose: To assess selected balloon-expandable and self-expanding stents for radial force, flexibility, radio-opacity, and trackability,
and to relate these physical characteristics to potential indications for placement.
Methods: Force–strain curves were plotted for each stent and the force required to produce 50% luminal narrowing was recorded. The
ability of the stent to show elastic recoil following deformation was also noted. Flexibility was measured by bending the
stents against a force transducer and recording the force required per degree of flexion. Radio-opacity was measured by comparing
each stent against a standard aluminum step wedge. Trackability was measured by testing the ability of the stent on its delivery
system to track over angles of 90° and 60°.
Results: The balloon-expandable stents showed greater radial strength and radio-opacity but, apart from the AVE Iliac Bridge stent,
showed poorer flexibility and trackability. The self-expanding stents showed less radial force but were able to re-expand
following deformity. They were generally more flexible and had better trackability but lower radio-opacity.
Conclusion: There is no stent which exhibits all the ideal properties required and therefore the interventionist will need to keep a
range of stents available if all lesions are to be addressed. 相似文献

Purpose: To evaluate initial results in patients with epiphora secondary to obstruction of the nasolacrimal duct treated by placement
of a polyurethane stent, and to discuss the technical problems and complications arising during the procedure, with visualization
of the anatomy of the drainage apparatus using computed tomography (CT).
Methods: We inserted 20 polyurethane Song stents under fluoroscopic guidance after dacryocystography in 19 patients with grade 3–4
epiphora caused by idiopathic obstruction of the nasolacrimal duct. CT scans were obtained following stent placement in all
patients.
Results: We focus on the technical problems and complications that arose during these procedures. During negotiation of the guidewire
past the obstruction at the level of the junction of the duct with the lacrimal sac, the guidewire created a false passage
in a posterior suborbital direction in two cases and towards the posterior midline in another. In all cases the guidewire
was withdrawn and reinserted through the proper anatomic route without further difficulty or complications. In two cases the
stent was improperly positioned wholly or partially outside the nasolacrimal system (one medially, one posteriorly). In one
case the stent was removed and reinserted; in the other it remains in place and functional. CT was performed in all these
cases to ensure proper anatomic alignment and determine what had gone wrong. The epiphora was completely resolved in 13 cases
and partially relieved in four; there were three cases of stent obstruction. Epistaxis of short duration (1 hr) occurred in
seven patients and headache in one.
Conclusions: Treatment of epiphora with polyurethane stents is a technique that is well tolerated by patients and achieves a high success
rate, yet problems in placement may be encountered. Though no major consequences for patients are involved, cognizance of
such difficulties is important to avoid incorrect positioning of stents. 相似文献

Purpose: To evaluate the suitability of transbrachial access for endovascular renal artery interventions.
Methods: During 37 consecutive endovascular renal artery interventions, the transbrachial approach was used on nine patients (mean
age 63 years; range 41–76 years) for 11 renal artery procedures on native kidneys and one percutaneous transluminal angioplasty
(PTA) on a transplanted kidney. The reason for using transbrachial access was a steep aorta-renal angle in five, and severe
aorta-iliac atherosclerosis in the remaining patients. In addition to the intervention catheter in the left brachial artery,
an additional nonselective catheter for controlling the procedure was inserted transfemorally (six patients) or via the contralateral
brachial artery.
Results: Eleven interventions (six PTAs, five stents) were successfully completed. The one failure resulted from impenetrable subclavian
artery stenosis. The only major complication was a brachial artery pseudoaneurysm requiring surgical treatment.
Conclusion: Transbrachial access is an effective and relatively safe technique for renal artery interventions when transfemoral access
is not possible.
