Follow-up results of embolization therapy for palliation of incurable bladder carcinoma
1985
Embolization therapy of the renal artery (N=10), hypogastric arteries (N=18) and ureter (N=24) was performed in 41 patients with incurable bladder carcinoma for palliation of gross hematuria and severe dysuria. Careful follow-up of the patients until death gave a mean survival time of 12.3 months after embolization; 6 patients are still alive. The results show that embolization therapy is justified for management of bleeding and dysuric complaints. Ureteral occlusion alone has almost no effect on hematuria. Combined embolization procedures yield better results than occlusion of the vessels or the ureter. Ureteral occlusion with a detachable balloon is superior to embolization with tissue ad…
Transpenile Venenokklusion zur Therapie der erektilen Impotenz
1989
In 15 of 18 patients, 2 of them with previous surgery, transpenile venoablation was performed for treatment of erectile dysfunction due to cavernous leakage. In 4 this was combined with retrograde venooclusion via the internal iliac vein. In 4 patients normal erectile status could be obtained. In 3 other patients erections became possible with use of intracavernous vasoactive agents. In two only mild amelioration, and in two others no change of erectile dysfunction were obtained. Follow-up studies are yet missing in 3 patients. Complications of the procedure were not observed.
Ethylene-vinyl alcohol copolymer (Onyx®) transarterial embolization for post-traumatic high-flow priapism
2016
International audience; We report a case of high-flow priapism treated successfully with superselective embolization of the cavernous artery. A 16-year-old male developed post-traumatic priapism subsequent to a fall causing blunt perineal trauma. He presented to our hospital four days after trauma. Immediately after the injury, he suffered painless sustained incomplete erection. High-flow priapism was diagnosed on the basis of color doppler ultrasonography findings. Computed tomography scan showed a high-flow arterio-venous fistula with feeders from branches of the right internal iliac artery. Selective arteriography of the right internal pudendal artery demonstrated an arterio-cavernous fi…
Embolization with ethylene vinyl alcohol copolymer (Onyx®) for peripheral hemostatic and non-hemostatic applications: a feasibility and safety study
2018
International audience; Background: Onyx® is a liquid embolic agent, which is approved for the treatment of cerebral vascular lesions but still rarely used in peripheral interventional radiology. The goal of this study is to report the feasibility and safety of embolization with Onyx® for peripheral hemostatic and non-hemostatic endovascular procedures.Methods: Retrospective study of all consecutive patients who underwent visceral or peripheral embolization with Onyx® for hemostatic or non-hemostatic purpose in our department between May 2014 and November 2016. Demographic data, clinical presentation, underlying etiology, culprit vessel, endovascular procedure, pain during embolization, out…
Management of Lemierre Syndrome.
2022
Lemierre Syndrome is a rare form of septic thrombophlebitis of the head and neck veins, most typically of the internal jugular vein, which affects otherwise healthy adolescents and young adults after an oropharyngitis or other local infection. It is characterized by multiple septic embolization. Despite treatment, Lemierre Syndrome displays a high rate of in-hospital complications that include thrombus progression and a new peripheral septic embolization; moreover, it can be fatal or cause disabling sequelae. The mainstay of the treatment is antibiotic therapy; anticoagulation is often used, but its role is controversial. Surgical treatment is often necessary in case of peripheral septic le…
Chirurgische Therapie von Lebermetastasen kolorektaler Karzinome
2003
Resection is the only curative treatment of colorectal liver metastases proofed by a long-term follow-up. The operation is indicated if the metastases are completely removable with sufficient liver parenchyma remaining after resection and if the patient is fit for surgery. The resection is not indicated in cases with non resectable extrahepatic tumours and lymph node metastases distal the hepatoduodenal ligament. The postoperative mortality amounts to about 5 % and the 5-year-survival-rates range between 20 and 40 % depending on the selection of patients. Aims of new concepts of operative therapy are the improvement of resectability by preoperative portal vein embolization, the resection co…
Retrograde Venenokklusion - Zur Therapie der verlogenen Impotenz
1993
Retrograde occlusion of penile drainage veins can produce improvement in patients with impotence due to venous leaks. We performed 50 transfemoral and three transjugular procedures; 46 (86%) were technically successful. Clinical improvement was found in 24 out of the 46 procedures (52%). In 20 patients spontaneous intercourse became possible, in four this occurred after intracavernous injection of vaso-active substances. In eleven patients there was deterioration after one to twenty months; in seven this was treated by repeated venous occlusion. In 13 patients improvement has been maintained over a period of one to thirty months (average 10.5 months). There were no complications.
Arteriovenous fistula of the vertebral artery in a female infant with hypotonia and cephalocorporal disproportion
2010
Background: Congenital arteriovenous fistulas are exceptional in childhood and imply a therapeutic challenge. Case report: A 9-month-old female infant was studied for cephalocorporal disproportion, hypotonia, progressive muscular atrophy and hyperreflexia. Computed tomography of the brain and electroencephalography were normal. Electromyographic patterns suggested proximal myopathic involvement. A continuous murmur with systolic reinforcement was audible in the neck. Angioresonance detected intracranial aneurysmal dilatations behind the bulbo-medullary junction and cerebral panangiography evidenced a direct vertebrovertebral fistula with extra- and intra-cranial varices and extreme medulla…
Reinfarction Related to PTCA-Induced Coronary Embolism after Successful Thrombolytic Therapy
1989
Coronary embolism originating from residual thrombotic material is one of the complications arising during acute percutaneous transluminal coronary angioplasty (PTCA) in acute myocardial infarction. This case report describes a symptomatic embolization of the right posterolateral and right posterior descending branch during success-ful PTCA of a subtotal stenosis of the midright coronary artery after acute inferior myocardial infarction. Typical ECG signs of reinfarction were recorded. We succeeded in recanalizing these branches by superselective thrombolysis and angioplasty.
0197: Angiographically visible distal embolization is not linked with culprit lesion but with clinical characteristics
2016
Despite the recent improvements in percutaneous coronary intervention (PCI), angiographically visible distal embolization (AVDE) complicates 6 to 18% of ST elevation myocardial infarction (STEMI) treated with PCI, and is associated with poor clinical outcomes. Culprit lesion characteristics have been proved to be the main predictive factor of AVDE. But data regarding clinical characteristics predicting AVDE are lacking. We aimed to identify predictors of AVDE complicating PCI in STEMI management. 769 consecutive patients admitted for STEMI who underwent PCI were included. Clinical, angiographic and therapeutics characteristics were assessed for each patien. AVDE was defined as an abrupt ves…
