Initial Experience with the Eclipse Double-Lumen Balloon Catheter for Embolization of Cranial Vascular Malformations

Double lumen balloon catheters (DLBCs) have emerged as a potential alternative to single lumen balloon catheters (SLBCs) for endovascular embolization of arteriovenous malformations (AVMs) and dural arteriovenous fistulas (dAVFs). This study describes our preliminary experience with the Eclipse 2L DLBC in treating AVMs and dAVFs. Patients who underwent embolization of cranial dAVFs or AVMs at our institution from August 2021 to March 2024 were included. Spinal vascular malformations were excluded. Descriptive statistics were used to analyze procedural outcomes, technical nuances and post-operative outcome on follow-up. 25 patients who underwent 38 embolization procedures (15 AVMs and 23 dAVFs) met criteria for inclusion in this study. The mean age of the cohort was 52.44 (standard deviation (SD)= 17.26), and 48% of the overall cohort (n= 13) was female. The average procedure times for AVMs and dAVFs were 80.4 minutes and 96.73 minutes, respectively. There was one instance of catheter entrapment. Two patients in the AVM cohort experienced mortality and one experienced post-operative rupture. Our preliminary experience using the Eclipse 2L balloon catheter for Onyx embolization reported procedural outcomes comparable to other DLBCs despite relatively higher procedure times and radiation doses. Further long-term studies on its efficacy as primary modality in treating AVMs and dAVFs are encouraged.

Use of a Balloon Catheter for Occlusion of Iatrogenic Direct Carotid-Cavernous Fistula Occurring during a Neurointerventional Procedure

Neurointerventional procedures involving the anterior circulation, including aneurysm coiling, mechanical thrombectomy (MT), and intracranial angioplasty, can result in rare life-threatening complications such as iatrogenic carotid-cavernous fistulas (CCFs). Here, we describe the successful use of a balloon catheter for the occlusion of an iatrogenic CCF during neurointerventional procedures in a 78-year-old woman. The patient underwent successful MT for right middle cerebral artery occlusion; however, her symptoms worsened the day after the procedure; therefore, intracranial stenting was planned. An iatrogenic CCF that occurred during the neurointerventional procedure was successfully occluded using a balloon catheter. Neurointerventionalists should be aware of iatrogenic CCFs and be prepared to treat this rare complication. The double-lumen balloon catheter may be a useful tool for the transarterial treatment of iatrogenic CCFs.

Balloon Mitral Valvotomy With the Accura Double-Lumen Balloon Catheter: Immediate and One-Year Clinical Outcomes.

ObjectiveDespite the decline in the incidence of rheumatic heart disease in developed countries, the disease still remains endemic among individuals of low socioeconomic status. The aim of the study is to assess immediate and one-year outcomes of balloon mitral valvotomy using the double-lumen Accura balloon (Vascular Innovations Co., Nonthaburi, Thailand) in patients with mitral valve stenosis.MethodsThis was a single-centre, observational, investigator-initiated retrospective study. All consecutive patients undergoing balloon mitral valvotomy with the Accura balloon between January 2015 and June 2020 were included. The primary endpoint was procedural success defined as an increase in mitral valve area (MVA) ≥50% from basal valve area or final valve area of ≥1.5 cm2, in the absence of mitral regurgitation grade >2. Clinical, echocardiographic, and haemodynamic parameters were assessed at the one-year follow-up.ResultsA total of 62 patients underwent balloon mitral valvotomy. The mean age was 34.9 ± 8.0 years, and 54 (87.1%) patients were female. Mean Wilkins' echo score was 7.5 ± 0.5. Procedural success was achieved in 59 (96.7%) patients. Mean MVA increased from 0.75 ± 0.14 cm2 to 1.64 ± 0.21 cm2, and mean mitral valve gradient decreased from 24.9 ± 5.5 mmHg to 7.30 ± 1.40 mmHg. Atrial fibrillation, mitral valve replacement, and moderate to severe mitral regurgitation occurred in 36 (59.0%), two (3.3%), and two (3.3%) patients, respectively. No death, cerebrovascular accidents, restenosis, or redo procedures occurred.ConclusionBalloon mitral valvotomy using the double-lumen Accura balloon is safe in patients with mitral valve stenosis.

Deployment of low-profile flow-diverter through a double lumen balloon catheter (remo-diversion technique) to treat recurrent middle cerebral artery bifurcation aneurysm: A technical note.

Wide neck intracranial aneurysms are often difficult to treat with coiling alone, and sophisticated techniques such as balloon-assisted coiling, stent-assisted coiling, flow-diversion, or intrasaccular flow-disruption are sometimes required.This technical note reports the endovascular treatment of a recurrent middle cerebral bifurcation aneurysm by remodeling technique followed by flow-diverter (Silk Vista Baby) deployment through a remodeling balloon (double lumen balloon Eclipse 2L).

Transarterial Treatment of Cranial Dural Arteriovenous Fistulas: The Role of Transarterial and Transvenous Balloon-Assisted Embolization.

Treatment of dural arteriovenous fistulas can be performed by transarterial or transvenous accesses. For those fistulas located at a dural sinus wall, obliteration of the sinus might lead to a substantial risk of complications if the occluded sinus impairs normal venous drainage. For those fistulas with direct leptomeningeal venous drainage, navigation to reach the arteriovenous shunting point of a leptomeningeal vein is usually technically demanding. We report the outcomes of patients with dural AVFs treated by transarterial injection of liquid embolic agents assisted by transarterial double-lumen balloon catheters and/or transvenous balloon catheters. This was a retrospective, 3-center study including patients with dural AVFs treated with a balloon-assisted technique in at least 1 treatment session. Angiographic follow-up was performed at 6 months. Clinical assessment was performed at admission and discharge and was reassessed at 30-day and 6-month follow-ups. Forty-one patients with 43 dural AVFs were treated. Thirty-four fistulas were located at a dural sinus wall. Treatment was performed using only a transarterial approach in 42 fistulas. Only 1 session was needed for complete obliteration of the fistula in 86% of the patients. Immediate complete angiographic occlusion was achieved in 39 fistulas. Of the 41 controlled fistulas, 40 (97.6%) were completely occluded at 6 months. Thirty-nine fistulas (95.1%) were cured without any report of major neurologic events or death during follow-up. Transarterial balloon-assisted treatment of dural AVFs with or without transvenous balloon protection was shown to be safe and effective.

Double-Lumen Balloons, Are They Only Useful in Neurointerventions? Preliminary Outcomes of Double-Lumen Balloon-Assisted Embolization of Visceral Artery Aneurysms.

This study aimed to assess the feasibility and results of double-lumen balloon-assisted embolization of visceral artery aneurysms (VAAs). Nine patients (mean age, 55.3 ± 10.8 years) diagnosed with VAA (superior mesenteric, n = 5; splenic, n = 2; renal, n = 2) and undergoing double-lumen balloon-assisted embolization were included in this study. Magnetic resonance angiogram (MRA) was used in the 6-month follow-up to assess the aneurysms and patency of the parent arteries. All patients were successfully treated with no reports of morbidity or mortality. Residual filling of the aneurysm neck was detected in 2 patients at the end of the procedure, but those parts were found to be stable in the sixth-month MRA. In 1 patient with renal aneurysm, a stent had to be deployed using a double-lumen balloon catheter because of the prolapse of the coil into the main artery. In another patient with a very large-necked superior mesenteric artery aneurysm, additional coils could be used at the same time thanks to the double-lumen balloon as the coils were not stabilized enough during embolization with the microcatheter coils. Liquid embolic agent was also used in this patient from the same lumen because of the large diameter of the aneurysm. Double-lumen balloons, which are mostly used in neurointerventional procedures, can be efficiently used as in the treatment of VAAs due to their ability to deploy stent and perform coil-liquid embolization through 1 lumen.

Endovascular Management of Cerebral Aneurysm: The Recent Trends

AbstractCerebral aneurysm rupture is the leading cause of mortality and morbidity in patients with hemorrhagic stroke. Surgical clipping and endovascular coiling are the mainstay of management for securing the aneurysm. After International Subarachnoid Aneurysm Trial (ISAT) and Barrow Ruptured Aneurysm Trial (BRAT) results, worldwide trend has shifted gradually in favor of endovascular management. Nonetheless, endovascular management was faced with some limitations, especially while treating giant, wide neck bifurcation, blister, and small uncoilable aneurysm. The recent introduction of new devices such as flow diverter stents, microstents, bifurcation devices, double-lumen balloon catheters, and microcoils have proved to be effective in overcoming the limitations of traditional aneurysm coiling. The authors present a review of recent advances in the endovascular management of cerebral aneurysm.

Adjunct to Embolize the High-Flow Fistula Part of Arteriovenous Malformation Using a Double-Lumen Balloon Catheter

The purpose of this study is to report our initial experience of Onyx embolization of the high-flow fistula part of arteriovenous malformation (AVM) using a double-lumen balloon catheter. A Scepter C balloon catheter was used in 2 patients with AVMs associated with high-flow fistulas. The fistulas were located in the anterior cerebral artery and the middle cerebral artery. Onyx embolization was successful in 2 cases, resulting in elimination of the high-flow fistula part of the AVM. There were no treatment-related events. The double-lumen Scepter balloon appears to be a safe and convenient device for Onyx embolization of high-flow fistulas.

Novel use of a double lumen balloon catheter for venous sinus thrombolysis and venoplasty

We describe the novel use of a double lumen balloon catheter for venous sinus thrombolysis and venoplasty. Cerebral venous sinus thrombosis is a rare disease that is usually treated with medical anticoagulation. In certain refractory cases, surgical or endovascular thrombolysis and thrombectomy may be required. A 48year-old man on anticoagulation for cerebral venous sinus thrombosis presented with nausea, vomiting and worsening hemiparesis. The patient underwent endovascular venous sinus thrombolysis and venoplasty with continuous in situ tissue plasminogen activator (tPA) infusion over 48hours. This novel approach to the endovascular treatment of venous sinus thrombosis, including the use of a double lumen balloon was advantageous, as it allowed direct infusion of tPA through the balloon catheter without having to exchange the balloon for a microcatheter.

Brief history of interventional radiology

In 1923, angiography was first successively used for the human body. In 1953, a Swedish doctor Sven-Ivar Seldinger pioneered the Seldinger technique, which laid down the foundation of interventional radiology. In 1963, Charles Dotter first proposed the idea of interventional radiology. In 1964, Charles Dotter opened a new era of percutaneous angioplasty through accidental operation, marking the formation of interventional radiology. On this basis, the techniques of balloon catheter dilation and metal stent implantation was developed. Endovascular stent was proposed in 1969. In 1973, the percutaneous angioplasty has been a breakthrough with the emergence of soft double-lumen balloon catheter. Percutaneous coronary angioplasty is applied in 1977. Since the 1990s, balloon angioplasty relegated to secondary status with the emergence of metal stent. Currently, endovascular stent have entered a new stage with the emergence of temporary stent and stent grafts and biological stent. Transcatheter arterial embolization had been one of the most important basic techniques for interventional radiology since 1965, it had also been a corresponding development with the improvement of embolic agents and catheter technology for the treatment of diseases now. Transjugular intrahepatic portosystemic stent-shunt is a comprehensive interventional radiology technology since 1967, in which the biliary system can be reached through a jugular vein, and the improvement appeared with balloon expandable stent in 1986.Since 1972, non-vascular interventional techniques was another important branch of interventional radiology. Currently, it is applied in the diagnosis and treatment of many diseases of the internal organs like the pancreas, liver, kidney, spinal cord, Fallopian tubes, esophagus and other organs. In 1973, Chinese radiologist first conducted the angiography test. Interventional radiology was introduced into China in the 1980s, it was readily developed through the sponsoring of training class (1981) and academic conferences (1986). Along with the return of the overseas scholars, the gap in the interventional diagnosis and treatment technology between China and the world has been narrowing since the 1990s.

Onyx embolization using dual-lumen balloon catheter: Initial experience and technical note

Onyx as an embolization agent for the management of vascular malformation is well established. We report our initial experience with dimethyl-sulphoxide (DMSO) compatible double lumen balloon catheters used for Onyx embolization. Between December 2011 and March 2013, we treated 22patients aged between 1.5 to 70years with two types of DMSO compatible dual-lumen balloon catheters (Scepter C and Ascent) to treat dural arteriovenous fistulas, brain arteriovenous malformation (AVM) with dural feeders, mandibular, facial, lingual, vertebral and paravertebral AVMs. The catheter has good navigability, compliant balloon on inflation formed a "plug" that has more resistance than Onyx plug enhancing better penetration. During injection, the balloon remained stable without spontaneous deflation or rupture and withstood the pressure build-up well. The retrieval of the catheter in most cases took less than a minute (19/28) while in five, it was less than five minutes and in the remaining four, it was longer that includes a trapped catheter on prolonged attempted retrieval resulted in an epidural hematoma, requiring emergent surgical evacuation. The fluoroscopy time is reduced, as we do not form a proximal onyx plug, the injection time is shorter along with easy and instantaneous removal of the catheter after balloon deflation in most cases. Dual-lumen balloon catheter Onyx embolization is a safe and effective technique. Currently, an important tool to circumvent some of the shortcomings associated with Onyx embolization. The catheter has good navigability, the balloon has stability, tolerance, enhances penetrability. It is easy to retrieve the microcatheter. With the experience gained, and with more compliant balloon catheters available, this technique can be applied to cerebral vessels in near future.

Initial Experience with the New Double-lumen Scepter Balloon Catheter for Treatment of Wide-necked Aneurysms

ObjectiveA new double-lumen balloon catheter was being developed for the treatment of cerebral aneurysms. The purpose of this study is to report our initial experience of a double-lumen balloon catheter for the treatment of wide-necked aneurysms.Materials and MethodsSeventeen patients (mean age, 63 years; range, 45-80 years) with wide-necked, with or without a branch-incorporated aneurysms, (10 ruptured and 9 unruptured) were treated with balloon-assisted coil embolization using a double-lumen balloon catheter (Scepter C™ or Scepter XC™) for 7 months after being introduced to our country. Locations of the aneurysms were posterior communicating artery (n = 7), anterior communicating artery or A2 (n = 7), middle cerebral artery (MCA) bifurcation (n = 3), basilar artery tip (n = 1) and anterior choroidal artery (n = 1). The initial clinical and angiographic outcomes were retrospectively evaluated.ResultsCoil embolization was successfully completed in all 19 aneurysms, resulting in complete occlusions (n = 18) or residual neck (n = 1). In one procedure, a thrombus formation was detected at the neck portion of the ruptured MCA bifurcation aneurysm near to the end of the procedure. It was completely resolved with an intra-arterial infusion of Glycoprotein IIb/IIIa inhibitor (Tirofiban, 1.0 mg) without any clinical sequela. There were no treatment-related events in the remaining 18 aneurysms. At discharge, functional neurological state improved in 11 patients (10 patients with ruptured aneurysm and 1 with unruptured aneurysm presenting with mass symptoms) and 6 patients with unruptured aneurysms had no newly developed symptoms.ConclusionIn this preliminary case series, the newly developed double-lumen Scepter balloon appears to be a safe and convenient device for coil embolization of wide-necked aneurysms.

Quality Improvement Guidelines for Transjugular Intrahepatic Portosystemic Shunt (TIPS)

Portal hypertension is a syndrome caused by increased resistance in the portohepatic circulation and an increase in the splanchnic vein blood supply. In the normal liver, the difference between pressures in the portal vein and the free hepatic veins or right atrium usually does not exceed 5 mm Hg. Portal hypertension is defined as a gradient larger than 6 mm Hg, but clinical complications seem to occur only when the pressure gradient exceeds 10–12 mm Hg. Wedged hepatic pressure measurement has two components. The portal component is the pressure transmitted from the hepatic sinusoids, and the systemic component is the blood pressure transmitted from the central veins. It is the portal component that causes the development of portal systemic collaterals. The term corrected sinusoidal pressure includes only the portal component and is calculated by subtracting the mean right atrial or inferior vena cava pressure from the wedged hepatic venous pressure. Wedged hepatic pressure is obtained through an end-hole catheter that is advanced into a hepatic vein until it can go no further. Alternatively, pressure can be measured through the wire channel of a double lumen balloon catheter inflated in a more central vein. Transjugular intrahepatic portosystemic shunt (TIPS) is the percutaneous method of creating a portosystemic shunt to decrease or treat portal hypertension. TIPS is a side-to-side shunt of a determined diameter designed to function as a partial shunt that preserves a portion of portal flow to the liver [2]. Flow through the completed shunt is assessed by comparing the degree of preferential filling of the shunt to the that of the portal vein branches and portosystemic collaterals (mainly in the gastric veins). The identification of hepatofugal (reversed) blood flow in portal vein branches (total shunting) is a sign of good flow through the shunt. Technical success is defined as a decrease of the portosystemic pressure gradient to 12 mm Hg or less, or a reduction of at least 20 %. Clinical success is defined as cessation of variceal bleeding, decrease of ascites, and conversion into diuretic-sensitive ascites, as well as improvement of liver function in patients referred for massive thrombosis of hepatic veins. Hepatic encephalopathy is defined as the complex of all cerebral dysfunctions that can occur during the course of serious liver disease. Clinical symptomatology, which as a rule is potentially reversible, ranges from disorientation, somnolence, and lethargy to sopor and coma. Hepatic encephalopathy has three forms: type A, associated with acute liver failure; type B, associated with portosystemic bypass without liver disease; and type C, or chronic, associated with liver cirrhosis.

Use of a New Double-Lumen Balloon Catheter for Single-Catheter Balloon-Assisted Coil Embolization of Intracranial Aneurysms: Technical Note

The prevalence of intracranial aneurysms is approximately 2% with an annual rupture rate of 0.7%. We describe our initial feasibility experience using a new double-lumen balloon catheter for single-catheter balloon-assisted coil embolization of wide-neck intracranial aneurysms. Two patients with large wide-neck intracranial aneurysms were referred for endovascular therapy. Endovascular treatment in the form of coil embolization alone was not feasible given the angioarchitecture of the aneurysms. Balloon-assisted coil embolization was planned. The patients underwent balloon-assisted coil embolization using the Ascent double-lumen balloon catheter (Micrus, San Jose, California). The balloon portion of the catheter was placed into the proximal neck of the aneurysm. The balloon was inflated and coil embolization performed through the inner lumen of the catheter. There were no procedural complications. Both aneurysms were successfully coiled by using the Ascent balloon occlusion catheter. The single-catheter balloon-assisted coil embolization technique can be performed safely and effectively with the Ascent double-lumen balloon catheter.

SU-FF-T-19: Accelerated Partial Breast Irradiation With Shielded MammoSite-Type Applicator

Purpose: We propose a method to improve delivery of APBI and therefore improve patient access to BCT. Method and Materials: BCT in conjunction with accelerated partial breast irradiation (APBI), using for instance the Hologic MammoSite applicator, is becoming popular due to the good dose distribution, and relatively short five day treatment procedure. Brachytherapy‐based APBI procedures typically work by implanting a double lumen balloon catheter in the lumpectomy cavity of breast following surgery. The balloon is inflated with an iodine‐based material mixed with saline. If the skin to balloon distance is less than 7mm, the procedure may not be recommended due to adverse skin reactions leading to poor cosmesis. This problem could be avoided by partially shielding the radiation dose to the skin by introducing a thin layer of high density material (high Z powder) inside the balloon catheter. In this case, the metalpowders may be controlled by a relatively weak external magnetic field applied externally to the patient to form an internal shielding layer inside the balloon in the region of concern, thus avoiding radiation damage to the skin.Results: Our preliminary results indicate that if, for example, the skin‐to‐balloon spacing is only 4 mm, when about 2 mm thin layer of ironpowders arranged internally under that segment of surface of the MammoSite balloon will decrease the skindose to an acceptable level. Our laboratory tests show that only a slight magnetic filed is required to bring such a small amount of ferrous powders to controllable configuration. Conclusion: The suggested approach will improve cosmetic outcome for all APBI patients treated, in addition to increasing survival expectancy and minimizing negative side effects.

Bladder inhibition or excitation by electrical perianal stimulation in a cat model of chronic spinal cord injury

To test the hypothesis that perianal electrical stimulation (PES) in chronic spinal cord-injured (SCI) cats could induce frequency-dependent inhibitory or excitatory reflex bladder responses. The experiments were conducted > or =4-5 weeks after spinal cord transection at the T9-T10 level. PES was applied via a pair of hook electrodes to the perianal skin area in three awake female cats with chronic SCI. A double-lumen balloon catheter was inserted through the urethra into the bladder to monitor bladder pressure and infuse saline (2-4 mL/min). Under isovolumetric conditions PES at 3-10 Hz significantly inhibited large-amplitude reflex bladder activity induced by bladder distension above the micturition volume threshold. However, PES at 20-50 Hz induced large-amplitude bladder contractions when the bladder volume was below the micturition volume threshold. Inhibitory PES (7 Hz) significantly increased the mean (sem) bladder capacity by 40 (10)% when it was applied continuously during cystometrography. The optimum excitatory PES (30 Hz) induced large-amplitude (>25 cmH(2)O), long-duration (>20 s) bladder contractions at a wide range of bladder volumes (10-90% of bladder capacity). This study showed that activation of pudendal afferent fibres by PES could induce frequency-dependent reflex bladder responses in awake cats with chronic SCI, indicating that a possible noninvasive treatment based on PES could be developed to restore both continence and micturition function for patients with SCI.

Catheter-Assisted Vein Sclerotherapy: A New Approach for Sclerotherapy of the Greater Saphenous Vein with a Double-Lumen Balloon Catheter

We sought to optimize sclerotherapy of the greater saphenous vein (GSV) by targeted application of foamed sclerosant by using a catheter. We designed a new double-lumen catheter that is inserted into the GSV. Via one lumen, a balloon at the tip of the catheter can be inflated to stop the blood flow. Via the second lumen, the sclerosing agent can be injected and aspirated. This method enabled us to perform a targeted application of the sclerosing agent [catheter-assisted vein sclerotherapy (KAVS)]. In an open study, outpatients suffering from varicosis of the GSV received a foam sclerotherapy under ultrasound guidance, using the newly developed KAVS catheter. Thirty patients with an insufficiency (reflux) of the GSV were treated with the newly developed KAVS method using foamed polidocanol. The intervention was well tolerated in all patients without the occurrence of serious side effects. In 27 of the 30 treated patients (90%), we found a closure of the GSV at control visits 6 weeks, 3 months, and 6 months after treatment. The KAVS method represents a feasible approach for sclerotherapy of the GSV. The efficiency and treatment modalities need to be explored in further studies.
