Project description:Background and study aims Endoscopic injection of gastric varices (GVs) using cyanoacrylate (CYA) is associated with significant adverse events (AEs). We aimed to compare the efficacy and safety of endoscopic ultrasound (EUS)-guided CYA injection into the perforating vein versus direct endoscopic injection (DEI) of CYA in treatment of high-risk GVs. Patients and methods This was a randomized controlled trial that included 52 patients with high-risk GVs. Group A underwent EUS-guided injection into the perforator vein and Group B underwent DEI of 1 mL CYA. Endoscopic examination and Doppler EUS were repeated after 3 months to confirm eradication. Obliteration by Doppler EUS was considered by absence of Doppler flow within the varix. Repeated injection was performed in the absence of obliteration. Doppler EUS examination was repeated at 3 and 6 months after each injection. Results Forty-three patients including 27 males and 16 females with mean age 57 years completed the study. Variceal obliteration was achieved during the index session after 3 months in eight of 21 (38.1 %) in group B compared to 17 of 22 (77.2 %) in group A ( P = 0.014). There was a significant difference in the amount of CYA needed to achieve obliteration in group B compared to group A (2 vs.1 mL, P = 0.027). There was no statistically significant difference in the overall AE rate between group A and group B (4.5 % vs. 14.3 %, P = 0.345). Conclusions EUS-guided CYA injection into the perforating veins achieved less amount of CYA, fewer number of sessions to obliteration, and similar overall AE rates in the treatment of high-risk GVs compared to DEI.
Project description:AIM:To compare n-butyl-2-cyanoacrylate, iso-amyl-2-cyanoacrylate and a mixture of 72% chromated glycerin with hypertonic glucose solution in management of gastric varices. METHODS:Ninety patients with gastric varices presented to Endoscopy Unit of Ain Shams University Hospital were included. They were randomly allocated into three groups; each group included 30 patients treated with intravariceal sclerosant injections in biweekly sessions till complete obturation of gastric varices; Group I (n-butyl-2-cyanoacrylate; Histoacryl(®)), Group II (iso-amyl-2-cyanoacrylate; Amcrylate(®)) and Group III (mixture of 72% chromated glycerin; Scleremo(®) with glucose solution 25%). All the procedures were performed electively without active bleeding. Recruited patients were followed up for 3 mo. RESULTS:26% of Scleremo group had bleeding during puncture vs 3.3% in each of the other two groups with significant difference, (P < 0.05). None of Scleremo group had needle obstruction vs 13.3% in each of the other two groups with no significant difference, (P > 0.05). Rebleeding occurred in 13.3% of Histoacryl and Amcrylate groups vs 0% in Scleremo group with no significant difference. The in hospital mortality was 6.6% in both Histoacryl and Amcrylate groups, while it was 0% in Scleremo group with no significant difference. In the first and second sessions, the amount of Scleremo needed for obturation was significantly high, while the amount of Histoacryl was significantly low. Scleremo was the less costly of the two treatments. CONCLUSION:All used sclerosant substances showed efficacy and success in management of gastric varices with no significant differences except in total amount, cost and bleeding during puncture.
Project description:Traumatic pseudoaneurysm of limb arteries are relatively rare. A 70-year-old gentleman, with history of mechanical aortic valve implantation on warfarin, presented to the emergency department with pain and swelling in the right leg. He had sustained blunt injury to the leg, a week prior to presentation. On examination, the lateral compartment of the leg was swollen, ecchymotic, and tense. Distal pulses were well palpable. An ultrasound Doppler evaluation revealed a large intramuscular hematoma in the lateral compartment with a pseudoaneurysm of a muscular branch of the anterior tibial artery. An ultrasound-guided compression of the pseudoaneurysm was initially attempted for 24 hours, which failed in closing off the pseudoaneurysm. He was subsequently taken up for thrombin injection into the pseudoaneurysm, which resulted in instant thrombosis of the pseudoaneurysm, with an uneventful clinical course thereafter. Thrombin injection is an effective and safe modality to treat pseudoaneurysms of limb arteries.
Project description:IntroductionGastric variceal (GV) bleeding is a feared complication of cirrhosis. Traditional endoscopic treatment with cyanoacrylate (CYA) injection can be challenging. Alternatively, endoscopic ultrasound (EUS)-guided delivery of hemostatic coils has shown high therapeutic success without the complications profile of CYA alone. Our aim was to compare the clinical outcomes of EUS-guided coil embolization with endoscopic CYA injection for the treatment of GV.MethodsWe performed a matched cohort study using a prospective registry involving 2 tertiary centers. A total of 10 patients undergoing EUS-based coil therapy were matched in 1:3 fashion to 30 patients who underwent CYA injection. The matching criteria included type of GV, Charlson comorbidity index, and bleeding severity. Primary outcomes were technical success and complications. Secondary outcomes were rebleeding rates, reinterventions rates, total transfusion requirements, and time-to-event analysis (rebleeding, reintervention, and transfusion).ResultsTechnical success was 100% for EUS coil therapy vs 96.7% for CYA injection (P = 1.0). Complication rates were 10% in the EUS coil group vs 20% in the CYA group; P = 0.65. At 9 months, no EUS coil patient had rebled compared with 38% of the CYA group. No EUS coil patient required blood transfusion for GV rebleed, whereas over 50% of CYA patients did. Ten percent of EUS coil patients required reintervention compared with 60% of CYA patients. The EUS coil group had superior time to reintervention, GV rebleed, and transfusions (all P < 0.05).DiscussionCompared with CYA, EUS-guided coil injection appears superior for the treatment of GV and should be considered initial endoscopic treatment of choice in centers with interventional EUS expertise.
Project description:A 69-year-old patient underwent an urgent aortic valve replacement because of Streptococcus agalactiae endocarditis of his native aortic valve. Since a rapid progression of the former abscess cavity into an aortic root pseudoaneurysm with increasing paravalvular regurgitation during postoperative follow-up, reoperation was performed. In the preoperative transesophageal echocardiography (TEE) images the pseudoaneurysm completely surrounds the left coronary artery (LCA) without any signs of myocardial ischemia.
Project description:We present a case report of an 84-year-old male who presented with a profunda femoris artery (PFA) pseudoaneurysm 8 years after the index revision total hip arthroplasty procedure. Failure of revision hardware and subsequent migration of implants led to damage of the PFA and pseudoaneurysm formation. The patient was hemodynamically unstable on presentation and required emergent endovascular intervention. Once medically stabilized, the patient underwent extensive debridement of the aneurysm and hematoma bed and broken hardware was removed to prevent further complications. At 6-month follow-up, the patient was able to mobilize independently and had returned to all prior levels of activities of daily living. We discuss the vascular anatomy of the hip, the paucity of literature on PFA pseudoaneurysm, as well as the likely etiology of total hip arthroplasty failures.
Project description:We report the case of a ruptured middle cerebral artery aneurysm that showed pseudoaneurysm formation in an intracerebral hematoma. A 61-year-old man who was taking warfarin complained of dysarthria. Three days later, he was found unconscious, and computed tomography on admission showed subarachnoid hemorrhage and an intracerebral hematoma in the left temporal lobe. Three-dimensional computed tomographic angiography showed an irregular-shaped aneurysm-like cavity extending from the left middle cerebral artery into the hematoma. Intraoperative observation revealed that the aneurysm itself was small and the lesion observed on computed tomography was a pseudoaneurysm that had formed in the hematoma. Pathologic examination of the aneurysm demonstrated that there was a thrombus at its tip. In this report, radiologic characteristics of three-dimensional computed tomographic angiography and etiology of a pseudoaneurysm in an intracerebral hematoma due to aneurysm rupture are discussed.
Project description:Submacular hemorrhage (SMH) following ruptured retinal artery macro aneurysm (RRAM) has better prognosis as compared to other etiologies. Timely intervention from as early as 24 h to less than 7 days is known to provide better visual outcomes in such cases. A variety of surgical techniques have been described in the treatment of RRAM. In this case report, we describe the advantages of intraoperative optical coherence tomography-guided sub-retinal injection of a cocktail mixture consisting of recombinant tissue plasminogen activator, bevacizumab, and air. Faster visual recovery with an immediate displacement of sub-macular bleed can be achieved with this technique in cases of RRAM-associated SMH.
