Disease Spectrum

Pancreatic arteriovenous malformation (PAVM) is a very rare and mostly congenital lesion, with less than 80 cases described in the English-published literature. It is defined as a tumorous vascular abnormality that is constructed between an anomalous bypass anastomosis of the arterial and venous networks within the pancreas. It represents about 5% of all arteriovenous malformations found in the gastrointestinal tract. Herein, we present a 64-year-old patient with symptomatic PAVM involving the body and tail of the organ, which was successfully treated by transcatheter arterial embolization. The disease spectrum and review of the literature are also presented.

Spinal Arteriovenous Malformations

Spinal vascular malformations are rare, with dural arteriovenous fistulas (AVFs) accounting for the majority of the pathology. Unlike spinal arteriovenous malformations, which cause abrupt neurological change as a result of hemorrhage, spinal dural AVFs tend to result in a progressive myelopathy through venous congestion and cord edema. If diagnosed and treated early with endovascular embolization or microsurgery, some deficits may be reversible.

Purpose. The aim of this study was to evaluate the safety and efficacy of transcatheter arterial embolization (TAE) in patients with renal hemorrhage after percutaneous nephrolithotomy (PCNL) and evaluate the risk factors that may result in severe bleeding requiring TAE. Methods. We retrospectively reviewed 121 patients with post-PCNL renal hemorrhage. Thirty-two patients receiving endovascular embolization were compared with 89 patients only receiving conservative treatment. The demographic and clinical data were recorded and compared between the two groups. The values of estimated glomerular filtration rate (eGFR) and serum creatinine (SCr) were recorded preoperatively, postoperatively, and at last follow-up and analyzed to evaluate the safety and efficiency of TAE. Results. The successful hemostasis rate of conservative therapy was 73.6% (89/121) and that of TAE was 100% (32/32). SCr and eGFR were not significantly different before PCNL and after the last follow-up of TAE (SCr: 0.95 vs. 0.95 mg/dl, P=0.857; eGFR: 86.77 vs. 86.18 ml/min/1.73m2, P=0.715). The univariate analysis demonstrated that advanced age, urinary tract infection, and diabetes mellitus were significantly associated with severe bleeding during PCNL. Multivariate analysis further identified that diabetes mellitus was an independent risk factor for severe bleeding needing TAE [odds ratio (OR): 3.778, 95% confidence interval (CI):1.276-11.190, and P=0.016]. Conclusion. TAE is a safe and effective procedure to treat renal hemorrhage that cannot be resisted by conservative treatment after PCNL. Diabetes mellitus was associated with high risks of severe bleeding needing TAE after PCNL.

Spinal Dural Arteriovenous Fistulas

Abstract: Spinal dural arteriovenous fistulas are a rare cause of congestive myelopathy. Symptoms are insidious in onset and may be confused with degenerative spinal disease. MRI characteristically shows edema of the spinal cord with serpiginous flow voids that follow the surface of the spinal cord. Careful evaluation with spinal angiography is required to ensure accurate diagnosis. Spinal dural arteriovenous fistulas differ from spinal arteriovenous malformations in that most fistulas have only a single fistulous point without a nidus. Spinal dural arteriovenous fistulas may be treated successfully with either surgical resection or endovascular embolization depending on their anatomy. Earlier treatment is associated with better outcomes.

Arteriovenous Fistulas

Introduction Dural arteriovenous fistulae (DAVF) are vascular lesions with arteriovenous shunting that may be treated with surgical obliteration or endovascular embolization. Some DAVF, such as anterior cranial fossa DAVF (AC-DAVF) derive their arterial supply from ophthalmic artery branches in nearly all cases, and trans-arterial embolization carries a risk of vision loss. We determined the efficacy and safety of trans-ophthalmic artery embolization of DAVF. Materials and methods We performed a retrospective cohort study of all patients with DAVF treated by trans-ophthalmic artery embolization from 2012 to 2020. Primary outcome was angiographic cure of the DAVF. Secondary outcomes included vision loss, visual impairment, orbital cranial nerve injury, stroke, modified Rankin Scale at 90-days, and mortality. Results 12 patients met inclusion criteria (9 males; 3 females). 10 patients had AC-DAVF. Patient age was 59.7  ±  9.5 (mean ± SD) years. Patients presented with intracranial hemorrhage (4 patients), headache (4 patients), amaurosis fugax (1 patients), or were incidentally discovered (2 patients). DAVF Cognard grades were: II (1 patient), III (6 patients), and IV (5 patients). DAVF were embolized with Onyx (10 patients), nBCA glue (1 patient), and a combination of coils and Onyx (1 patient). DAVF cure was achieved in 11 patients (92%). No patients experienced vision loss, death, or permanent disability. One patient experienced a minor complication of blurry vision attributed to posterior ischemic optic neuropathy. 90-day mRS was 0 (10 patients) and 1 (2 patients). Conclusions Trans-ophthalmic artery embolization is an effective and safe treatment for DAVF.

Brain Avms

Object High-flow fistulas associated with brain arteriovenous malformations (AVMs) pose a significant challenge to both stereotactic radiosurgery (SRS) and surgical treatment. The purpose of this study was to examine the outcomes of multimodality treatment of AVMs in association with a large arteriovenous fistula (AVF), with a special focus on endovascular embolization and its associated complications. Methods One hundred ninety-two patients harboring cerebral AVMs underwent endovascular treatment in the authors' department between 1997 and 2003. Of these, the authors selected 74 patients presenting with an AVM associated with high-flow AVF(s) for a retrospective analysis based on the findings of superselective angiography. After endovascular embolization, 32 patients underwent resection, 33 underwent either SRS or hypofractionated stereotactic radiotherapy (HSRT), and 3 underwent both surgery and SRS. Six patients underwent embolization only. Immediate and midterm treatment outcomes were analyzed. Results Fifty-seven (77%) of the 74 patients had AVMs that were Spetzler-Martin Grade III or higher. A complete resection was achieved in all 32 patients. Of patients who underwent SRS/HSRT, 13 patients (39.3%) had either complete or > 90% obliteration of the AVM, and 2 patients (6.1%) had incomplete obliteration. Fourteen patients (42.4%) with residual AVM underwent repeated radiotherapy (and remain under observation). Of the 3 patients who underwent both SRS and resection, resection was complete in 2 and incomplete in one. No follow-up was obtained in 6 patients (8.1%). An endovascular complication was observed in 4 patients (5.4%). Fistula embolization was safely performed in every patient, whereas every endovascular complication was associated with other procedures such as nidus embolization. Conclusions Endovascular occlusion of the fistulous component was successfully achieved in every patient; every endovascular complication in this series was related to other procedures such as nidus embolization. The importance of the fistula treatment should be emphasized to minimize the endovascular complications and to maximize the treatment effect when a multimodality therapy is used to treat brain AVMs with large AVF.

Purpose: Wunderlich syndrome (WS) with hypovolemic shock secondary to ruptured renal angiomyolipoma (rAML) represents an urgent condition. Hence, we reported our experience with transcatheter arterial embolization (TAE) using different embolic materials under this condition.Methods: This retrospective study consisted of 22 patients. Embolic materials including particles, microcoils, and liquid embolic agents were selectively used based on the decisions of interventional radiologists. Technical success was defined as the complete occlusion of bleeding vessels on the final renal angiogram. Clinical success was defined as the absence of re-hemorrhage needed for repeat endovascular or surgery treatment after TAE.Results: The articulated materials were used when WS presented without aneurysms; a combination of particulate materials and microcoils or Glubran 2 alone were used for WS with aneurysms. The technical success based on 24 episodes of TAEs in 22 patients was 100% (24 of 24). Repeat TAE was achieved in two patients with hemorrhages re-occurring two days after the initial embolization with microcoils alone. The clinical success was 90.9% (20 of 22). No nontarget embolization or embolization-related complications occurred during the TAE procedure. Of the patients, 27.3% (6 of 22) experienced minor complications of post-embolization syndrome (PES). During a median follow-up time of 34 months, no recurrent hemorrhage that required repeat endovascular or surgical treatment for hemostasis occurred.Conclusion: Urgent TAE with the selective use of different embolic materials is an effective alternative to control WS with hypovolemic shock secondary to ruptured rAML. The condition of presenting with or without aneurysms may determine the embolic materials employed.
