For the patients with chronic mesenteric ischemia, various surgical procedures can be performed to reestablish mesenteric blood flow. Recently endovascular procedure are also tried in selected patients. But there still exist debates on which procedure is easier and safer to perform and more endurable for this uncommon arterial lesion. We will discuss here the indications for treatment, the merits and demerits of vairous mesenteric revascularization procedures.

Hemangioblastoma is a benign and highly vascular tumor. Complete surgical resection of highly vascular tumor such as hemangioblastoma may be challenging due to excessive bleeding. Preoperative embolization of these lesions may decrease the intraoperative blood loss and facilitate excision. We report three cases of cerebellar hemangioblastomas that were embolized using Onyx.

Migration of coils during endovascular procedures is a rare, but well-known complication. We are reporting two cases of successfully retrieving migrated coil using detachable intracranial stent. In both of our cases there was distal migration of coil during the intracranial aneurysm coiling procedure. The Solitaire® AB stent (Covidien, Irvine, CA, USA) was used to retrieve those coils. The stent was passed distal to the migrated coil using standard technique. It was then partially deployed and gradually withdrawn along with the entangled coil. Coil retrieval using the fully retrievable intracranial stent is a very simple, safe and easily available alternative for retrieval of distally migrated coil.

Vascular surgeons encounter a myriad of complications during the management of patients. The complications that occur associated with vascular surgery are often life threatening. Vascular surgeons have played a pioneering role in the development and introduction of new vascular and endovascular techniques, and some of the techniques changed the therapeutic options available for patients with vascular disease. Especially, with the development of endovascular surgery, there has been substantial change in the management of most vascular diseases and their complications. The best way to manage complications is to prevent them from occurring by careful planning, appropriate patient selection, extensive operator experience, and the correct use of appropriate devices. Successful operation outcomes depend on avoiding complications, as well as recognizing and promptly managing complications when they occur. This article reviews various local complications and their management in the field of vascular and endovascular surgery.

The current assortment of microcatheters widely used for aneurysm coil embolization may not be well suited for several anatomic variants, including excessive vascular tortuosity and small aneurysms less than 3 mm. Longer microcatheters designed with a smaller caliber that can accommodate and deliver coils may be of use in these situations. This case series and literature review illustrates the advantages and limitations of the Marathon microcatheter (Covidien, Irvine, CA, USA) when used for coil embolization of cerebral aneurysms. Despite some technical compromises including the distal marker, length, and the risk of buckling, the Marathon microcatheter was able to adequately deliver coils to achieve satisfactory occlusion of cerebral aneurysms. We found unique advantages with regards to length and smaller distal outer diameter (OD). These results may serve as a guide for the further development of a microcatheter used for coil embolization that has the features of a smaller distal OD and longer length.

Retrograde type A aortic dissection (RTAD) following thoracic endovascular aortic repair is a devastating complication associated with high mortality rates. In particular, a deployed endograft in a bird-beak formation in an acute curve of the aortic arch can induce injury to the fragile aortic wall, with the subsequent development of RTAD. Here, we describe an extremely rare case of RTAD caused by fracture of the bare spring of the thoracic endograft for type A aortic dissection.

Endovascular recanalization therapy (ERT) has been proven its efficacy in improving prognosis of acute ischemic stroke with intracranial large artery occlusion. Before the DAWN and DEFUSE 3 trials, ERT was recommended for stroke patients who could be treated within 6 hours after the onset of symptoms and the prognosis after ERT has been known time-dependent. However, the most recently published 2 ERT trials performed more than time window of 6 hours showed significant efficacy of ERT to compare with conservative therapy in selected patients. Now we should apply the result of new trials of ERT in the extended time window clinically. Herein, the result of recent ERT trials and the predictive factors affecting prognosis beyond the concept of time in ERT will be discussed.

Background and Objective: Stroke has remained one of the primary causes of significant morbidity and mortality. Among the therapeutic options for acute stroke management, endovascular thrombectomy is intended to remove the thrombi within the intracerebral vasculature and restore adequate perfusion to the surrounding penumbra. It is recommended up to 24 hours from onset of neurologic symptom. In the Philippines, only a few tertiary healthcare institutions are able to offer and perform endovascular thrombectomies. The aim was to describe the profile and discharge outcomes of endovascular thrombectomy for acute ischemic stroke at a tertiary hospital in our country. Methods: We conducted a retrospective records review among 924 patients admitted for acute ischemic stroke from October 2018 to August 2021 who underwent mechanical thrombectomy. Clinical and functional outcomes were measured using the National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin Score (mRS). Results: Among 31 patients included in the study, 29 subjects (93.5%) had moderate to severe disability (mRS 3–5), and 25 (80.6%) had moderate stroke (NIHSS 6–21) on admission. The identified site of the cerebrovascular thrombi was within the M1 segment of the middle cerebral artery (41.9%, n=13). The stent retriever approach was performed in 19 participants (61.2%). Upon discharge, only 7 (22.6%) had favorable functional outcomes (MRS 0–2), and 9 (29.0%) resulted in mortality. Successful reperfusion was achieved in 92.3% of the patients. Conclusion Overall, endovascular thrombectomy is a possible treatment option for large vessel acute ischemic stroke in developing countries.

Endovascular aneurysm repair (EVAR) has been a revolutionary development in the treatment of abdominal aortic aneurysms (AAAs) since its introduction in the early 1990s. The result of the two randomized controlled trials comparing EVAR versus open repair for the treatment of AAAs has provided some insight to the advantages and limitations of EVAR technology. Endoleaks continue to be a challenge for EVAR and most endoleaks can now be successfully managed by endovascular techniques. Fenestrated and branched stent-graft technology is increasingly applied to patients with complex AAA anatomies. This paper outlines some of the concepts and discusses the controversies and challenges facing clinicians involved in EVAR today and in the future.
