Use of an amplatzer vascular plug in embolization of a pulmonary artery aneurysm in a case of hughes-stovin syndrome: a case report
<p>Abstract</p> <p>Introduction</p> <p>Hughes-Stovin syndrome is a rare condition characterized by peripheral deep venous thrombosis accompanied by single or multiple pulmonary arterial aneurysms. The limited number of cases has precluded controlled studies of the management of pulmonary artery aneurysms, which usually cause massive hemoptysis leading to death. This is the first report of a new endovascular treatment of a single large pulmonary arterial aneurysm.</p> <p>Case presentation</p> <p>An 18-year-old Caucasian man was referred to our department with recurrent severe hemoptysis. His medical history included Hughes-Stovin syndrome diagnosed during a recent hospital admission. The patient was initially treated with corticosteroids. Because of his recurrent hemoptysis, we decided to embolize a 3.5 cm pulmonary arterial aneurysm using an Amplatzer Vascular Plug. The procedure was not complicated, and the patient's post-intervention course was uneventful. The patient has remained free from any complications of the embolization 36 months after the procedure.</p> <p>Conclusion</p> <p>Percutaneous embolization of a single large pulmonary artery aneurysm with an Amplatzer Vascular Plug in a patient with Hughes-Stovin syndrome is a less invasive procedure that represents the best multidisciplinary approach in treating these patients.</p
Carotid Interventions Above and Below the Bulb
Atherosclerotic occlusive lesions of the common carotid artery (CCA), the internal carotid artery (ICA), and the intracranial branches are amenable to angioplasty and stenting. Non atheromatous occlusive lesions caused by fibromuscular dysplasia, arteritis, or trauma may also be treated by image guided intervention in selected patients. Aneurysmal lesions of the CCA, ICA and the intracranial branches of degenerative, mycotic or traumatic etiologies, as well as carotid cavernous fistulae are mostly best treated by embolization. Technological developments continuously expand the indications of interventional treatment in these vascular territories
Revisiting endovascular treatment in below-the-knee disease. Are drug-eluting stents the best option?
Patients with below-the-knee arterial disease are primarily individuals
suffering from critical limb ischemia (CLI), while a large percentage of
these patients are also suffering from diabetes or chronic renal failure
or both. Available data from randomized controlled trials and their
meta-analysis demonstrated that the use of infrapopliteal drug-eluting
stents (DES), in short-to medium-length lesions, obtains significantly
better results compared to plain balloon angioplasty and bare metal
stenting with regards to vascular restenosis, target lesion
revascularization, wound healing and amputations. Nonetheless, the use
of this technology in every-day clinical practice remains limited mainly
due to concerns regarding the deployment of a permanent metallic
scaffold and the possibility of valid future therapeutic perspectives.
However, in the majority of the cases, these concerns are not
scientifically justified. Large-scale, multicenter randomized controlled
trials, investigating a significantly larger number of patients than
those already published, would pro-vide more solid evidence and
consolidate the use of infrapopliteal DES in CLI patients. Moreover,
there is still little evidence on whether this technology can be as
effective for longer below-the-knee lesions, where a considerable number
of DES is required. The develo-pment and investigation of new, longer
balloon-expanding or perhaps self-expanding DES could be the answer to
this problem
Subclavian artery occlusion and pseudoaneurysm caused by lung apex mucormycosis: Successful treatment with transcatheter embolization
Subclavian artery pseudoaneurysm and occlusion in young patients are
usually post-traumatic. We report the case of a 33-year-old diabetic
woman with subclavian artery occlusion and pseudoaneurysm formation
caused by pulmonary mucormycosis infection. The patient presented with
diabetic ketoacidosis, Horner’s syndrome, and absent left arm pulses. A
cystic lesion of the left lung apex was found by imaging, was surgically
resected, and was histologically diagnosed as mucormycosis infection.
Magnetic resonance angiography depicted a left subclavian artery
pseudoaneurysm and occlusion adjacent to the mucormycosis lesion. To
protect against thromboembolic complications and rupture, the
pseudoaneurysm was embolized with coils. The patient is clinically well
1 year after the intervention with no perfusion of the pseudoaneurysm
Clinical Outcome and Safety of Multilevel Vertebroplasty: Clinical Experience and Results
To compare safety and efficacy of percutaneous vertebroplasty (PVP) when
treating up to three vertebrae or more than three vertebrae per session.
We prospectively compared two groups of patients with symptomatic
vertebral fractures who had no significant response to conservative
therapy. Pathologic substrate included osteoporosis (n = 77), metastasis
(n = 24), multiple myeloma (n = 13), hemangioma (n = 15), and lymphoma
(n = 1). Group A patients (n = 94) underwent PVP of up to three treated
vertebrae (n = 188). Group B patients (n = 36) underwent PVP with more
than three treated vertebrae per session (n = 220). Decreased pain and
improved mobility were recorded the day after surgery and at 12 and 24
months after surgery per clinical evaluation and the use of numeric
visual scales (NVS): the Greek Brief Pain Inventory, a linear analogue
self-assessment questionnaire, and a World Health Organization
questionnaire.
Group A presented with a mean pain score of 7.9 +/- A 1.1 NVS units
before PVP, which decreased to 2.1 +/- A 1.6, 2.0 +/- A 1.5 and 2.0 +/-
A 1.5 NVS units the day after surgery and at 12 and 24 months after
surgery, respectively. Group B presented with a mean pain score of 8.1
+/- A 1.3 NVS units before PVP, which decreased to 2.2 +/- A 1.3, 2.0
+/- A 1.5, and 2.1 +/- A 1.6 NVS units the day after surgery and at 12
and 24 months after surgery, respectively. Overall pain decrease and
mobility improvement throughout the follow-up period presented no
statistical significance neither between the two groups nor between
different underlying aetiology. Reported cement leakages presented no
statistical significance between the two groups (p = 0.365).
PVP is an efficient and safe technique for symptomatic vertebral
fractures independently of the vertebrae number treated per session
A survival analysis of patients with malignant biliary strictures treated by percutaneous metallic stenting
Background: Percutaneous metal stenting is an accepted palliative
treatment for malignant biliary obstruction. Nevertheless, factors
predicting survival are not known.
Methods: Seventy-six patients with inoperable malignant biliary
obstruction were treated with percutaneous placement of metallic stents.
Twenty patients had non-hilar lesions. Fifty-six patients had hilar
lesions classified as Bismuth type I (n = 15 patients), type II (n =
26), type III (n = 12), or type IV (n = 3 patients). Technical and
clinical success rates, complications, and long-term outcome were
recorded. Clinical success rates, patency, and survival rates were
compared in patients treated with complete (n = 41) versus partial (n =
35) liver parenchyma drainage. Survival was calculated and analyzed for
potential predictors such as the tumor type, the extent of the disease,
the level of obstruction, and the post-intervention bilirubin levels.
Results: Stenting was technically successful in all patients (unilateral
drainage in 70 patients, bilateral drainage in 6 patients) with an
overall significant reduction of the post-intervention bilirubin levels
(p < 0.001), resulting in a clinical success rate of 97.3%. Clinical
success rates were similar in patients treated with whole-liver drainage
versus partial liver drainage. Minor and major complications occurred in
8% and 15% of patients, respectively. Mean overall primary stent
patency was 120 days, while the restenosis rate was 12%. Mean overall
secondary stent patency was 242.2 days. Patency rates were similar in
patients with complete versus partial liver drainage. Mean overall
survival was 142.3 days. Survival was similar in the complete and
partial drainage groups. The post-intervention serum bilirubin level was
an independent predictor of survival (p < 0.001). A cut-off point in
post-stenting bilirubin levels of 4 mg/dl dichotomized patients with
good versus poor prognosis. Patient age and Bismuth IV lesions were also
independent predictors of survival.
Conclusions: Percutaneous metallic biliary stenting provides good
palliation of malignant jaundice. Partial liver drainage achieved
results as good as those after complete liver drainage. A serum
bilirubin level of less than 4 mg/dl after stenting is the most
important independent predictor of survival, while increasing age and
Bismuth IV lesions represent dismal prognostic factors
