INTRODUCTION
Pseudo aneurysm of the ankle is a rare presentation and the management is complex due to the complex anatomy. The aim of this review is to examine the epidemiology, etiology, diagnostic modalities used and management. This is the first systematic review of this topic in literature.
METHODS
We performed a systematic review in multiple databases (including PubMed, MEDLINE, EMBASE, and Scopus) from 1966 to May 18, 2019, to identify all case reports and case series describing patients with ankle pseudo aneurysm. This systematic review was performed in accordance with the Preferred Reporting Items for a Systematic Review and Meta-analysis (PRISMA). Our inclusion criteria included patients with ankle pseudo aneurysm of any age. We excluded reports in which the individual level data is not available. Patients demographic (gender, age), clinical characteristics (precipitating event, duration), diagnostic modality and treatment were recorded.
RESULT
There were in total 23 case reports identified on ankle pseudo aneurysm from 1966 until 2018. Among these twenty-three reports, 16 (70%) were male and seven (30%) patients were female. Age distribution showed higher number of reports among young adults, 15 patients (65%). Based on our systematic review trauma (48%), arthroscope (48%) and arthrodesis (4%) were the etiologies described in all these case reports. Ultrasound duplex and CT Angiogram has been used as a single modality in three reports each. In fifteen patients (65%) combination of imaging has been used for diagnosis. Anterior tibial artery is the most commonly injured vessel among the reported cases, comprised of 14 (61%) patients. Among these arthroscopes were the highest reported precipitating events, 9 (64%), followed by trauma in four patients (29%) and arthrodesis in one patient (7%). Treatment modalities described in all previous reports were excision and ligation, 10 (42%); excision of sac and primary repair, 4 (17%); excision of sac followed by reversed saphenous venous graft repair, 2 (8%); US guided compression, 2 (8%); US guided thrombin injection, 4 (17%); stenting, 1 (4%) and coiling, 1 (4%).
CONCLUSION
Ankle pseudoaneurysm is mostly preventable by detailed initial assessment following trauma or careful approach during arthroscope. Evolving diagnostic modality and treatment has shed some light into noninvasive management of pseudo aneurysm of ankle.

BACKGROUND
Penetrating vertebral artery injuries (VAIs) are rare. Because of their rarity, complex anatomy, and difficult surgical exposures, few surgeons and trauma centers have developed significant experience with their management. The objectives of this study were to review their incidence, clinical presentation, radiologic identification, management, complications, and outcomes and to provide a review of anatomic exposures and surgical techniques for their management.
METHODS
A literature search on MEDLINE Complete-PubMed, Cochrane, Ovid, and Embase for the period of 1893 to 2018 was conducted. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used. Our literature search yielded a total of 181 potentially eligible articles with 71 confirmed articles, consisting of 21 penetrating neck injury series, 13 VAI-specific series, and 37 case reports. Operative procedures and outcomes were recorded along with methods of angiographic imaging and operative management. All articles were reviewed by at least two independent authors, and data were analyzed collectively.
RESULTS
There were a total of 462 patients with penetrating VAIs. The incidence of VAI in the civilian population was 3.1% vs 0.3% in the military population. More complete data were available from 13 collected VAI-specific series and 37 case reports for a total of 362 patients. Mechanism of injury data were available for 341 patients (94.2%). There were gunshot wounds (178 patients [49.2%]), stab wounds (131 [73.6%]), and miscellaneous mechanisms of injury (32 [8.8%]). Anatomic site of injury data were available for 177 (49%) patients: 92 (25.4%) left, 84 (23.2%) right, and 1 (0.3%) bilateral. Anatomic segment of injury data were available for 204 patients (56.4%): 28 (7.7%) V1, 125 (34.5%) V2, and 51 (14.1%) V3. Treatment data were available for 212 patients. Computed tomography angiography was the most common imaging modality (163 patients [77%]). Injuries were addressed by operative management (94 [44.3%]), angiography and angioembolization (72 [34%]), combined approaches (11 [5.2%]), and observation (58 [27.4%]). Stenting and repair were less frequently employed (10 [4.7%]). The incidence of aneurysms or pseudoaneurysms was 18.5% (67); the incidence of arteriovenous fistula was 16.9% (61). The calculated mortality in VAI-specific series was 15.1%; in the individual case report group, it was 10.5%.
CONCLUSIONS
The majority of VAIs present without neurologic symptoms, although some may present with exsanguinating hemorrhage. Computed tomography angiography should be considered first line to establish diagnosis. Gunshot wounds account for most injuries. The most frequently injured segment is V2. Surgical ligation is the most common intervention, followed by angioembolization, both of which constitute important management approaches.

OBJECTIVE
True profunda femoris artery aneurysm (TPFAA) is rare. Most cases of profunda femoris artery aneurysm are classified as pseudoaneurysms. TPFAAs are mostly asymptomatic, but some are manifested with pain, swelling, paresthesia, gait and movement disturbances, thrombosis, and rupture. There is a paucity of evidence on the effectiveness of diagnostic and therapeutic measures for management of TPFAA. The aim of this paper was to systematically review the incidence, diagnosis, and management of TPFAA.
METHODS
A comprehensive systematic review on the diagnosis and management of TPFAAs was conducted by a search through PubMed, Cochrane, Embase, and Google Scholar databases to identify and to evaluate publications on TPFAA since 2012. Only publications on TPFAA were included in this review.
RESULTS
A total of 19 publications published from 2012 were included in the review. The studies were 18 case reports and a cadaver study reporting 27 TPFAAs in 26 patients with a mean age of 69.6 years. Rupture was reported in 18.5% of the cases (n = 5); the conventional clinical presentation of unruptured TPFAA was reported in 48% of cases (n = 13), with 40.9% of unruptured aneurysms being asymptomatic (n = 9). Computed tomography angiography was used as a diagnostic tool in 85.2% of the cases (n = 23); Doppler ultrasound was applied in 33.3% of cases (n = 9). The common therapeutic approaches were resection and revascularization (n = 13 [48.1%]) and ligation or resection without reconstruction (n = 6 [22.2%]). Cumulative analysis for cases reported before and after 2012 yielded similar results.
CONCLUSIONS
Review of the current literature supports that computed tomography angiography and Doppler ultrasound are the mainstay diagnostic approaches for TPFAA. Surgical repair through ligation, resection, and revascularization remains the most common and effective therapeutic procedure. Endovascular embolization is recommended for aneurysms when surgery is not tenable because of the patient's comorbidities and the aneurysm's anatomy.

Meta-Analysis
OBJECTIVE
Aneurysms arising from arteriovenous fistulae are a common finding among dialysed patients and pose a risk of acute bleeding. The aim of this study was to perform a systematic review and meta-analysis evaluating the surgical options for the treatment of aneurysmal arteriovenous fistulae.
METHODS
A systematic review and meta-analysis of articles published between January 1973 and March 2019 describing the surgical treatment of arteriovenous fistulae aneurysms.
RESULTS
A total of 794 records were identified. After duplicate and low quality studies were removed, 72 full text articles were reviewed and from these 13 were included in the meta-analysis. The total number of patients was 597. Aneurysms were located in the upper arm in 289 (59%) cases and the smallest diameter of a treated aneurysm was 15 mm. The most frequent indication for treatment was bleeding prevention in 513 (86%) cases. Aneurysmorrhaphy was the surgical method of choice in all 13 studies. The pooled primary patency at 12 months was 82% (95% CI 69%-90%, 12 studies, I = 84%, p < .01). The 12 month primary patency rates were similar for aneurysmorrhaphy with external prosthetic reinforcement (85%, 95% CI 71%-93%, two studies, I = 0%, p = .33) and aneurysmorrhaphy performed using a stapler (74%, 95% CI 61%-83%, four studies, I = 0%, p = .48) and without a stapler (82%, 95% CI 60%-94%, six studies, I = 92%, p < .01).
CONCLUSION
Aneurysmorraphy of arteriovenous fistulae is a procedure with acceptable short and long term results, with a low complication and aneurysm recurrence rate.

BACKGROUND
Gastroduodenal artery (GDA) pseudoaneurysm is a serious complication following pancreatic resection, associated with high morbidity and mortality rates. This review aimed to report the incidence of GDA pseudoaneurysm after pancreatic surgery, and describe clinical presentation and management.
METHODS
MEDLINE and Embase were searched systematically for clinical studies evaluating postoperative GDA pseudoaneurysm. Incidence was calculated by dividing total number of GDA pseudoaneurysms by the total number of pancreatic operations. Additional qualitative data related to GDA pseudoaneurysm presentation and management following pancreatic resection were extracted and reviewed from individual reports.
RESULTS
Nine studies were selected for systematic review involving 4227 pancreatic operations with 55 GDA pseudoaneurysms, with a reported incidence of 1·3 (range 0·2-8·3) per cent. Additional data were extracted from 39 individual examples of GDA pseudoaneurysm from 14 studies. The median time for haemorrhage after surgery was at 15 (range 4-210) days. A preceding complication in the postoperative period was documented in four of 21 patients (67 per cent), and sentinel bleeding was observed in 14 of 20 patients (70 per cent). Postoperative complications after pseudoaneurysm management occurred in two-thirds of the patients (14 of 21). The overall survival rate was 85 per cent (33 of 39).
CONCLUSION
GDA pseudoaneurysm is a rare yet serious cause of haemorrhage after pancreatic surgery, with high mortality. The majority of the patients had a preceding complication. Sentinel bleeding was an important clinical indicator.

OBJECTIVE
Upper extremity access (UEA) is an important component of complex fenestrated and branched endovascular aneurysm repair (F/BEVAR). Open and percutaneous UEA approaches have been reported during these procedures. The aim of this review was to assess the outcomes of UEA done to facilitate F/BEVAR.
METHODS
A systematic review of studies focusing on upper extremity arterial access during F/BEVAR was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. Three databases including PubMed MEDLINE, Embase, and Cochrane Library were queried. Outcomes of interest included UEA-related and other unrelated early and late morbidity and mortality, such as arterial occlusion, neurologic deficit, bleeding complications, and stroke, in patients undergoing UEA during F/BEVAR.
RESULTS
Five full-text manuscripts and one abstract met criteria to be included, accounting for a total of 495 patients. The median age of patients who underwent UEA during F/BEVAR was 73.4 years. Predominantly male patients (371 [74.9%]) were treated. Indications for F/BEVAR were thoracoabdominal aortic aneurysms in 325 (65.6%), pararenal aneurysms in 96 (19.4%), juxtarenal aneurysms in 44 (8.9%), and suprarenal aortic aneurysms in 30 (6.1%). Axillary conduits were created in 29 (5.8%) patients. A total of 41 (8.2%) UEA-related complications were reported. Of those 41 complications, 17 (41.5%) were access bleeding, 10 (24.4%) were ischemic strokes, 7 (17.1%) were arterial occlusions, 4 (9.7%) were upper extremity neurologic deficits, 2 (4.9%) were arterial stenoses, and 1 (2.4%) was pseudoaneurysm. UEA-related complications were reported in 15 of 56 (26.8%) patients undergoing percutaneous UEA and 26 of 439 (5.9%) undergoing open UEA (P < .001).
CONCLUSIONS
The overall complication rate associated with UEA during F/BEVAR is low, with 2% stroke rate reported. The percutaneous approach showed a higher UEA-related complication rate compared with open UEA. More studies on percutaneous UEA and randomized studies comparing open vs percutaneous UEA during F/BEVAR are warranted to determine the safest and most efficient UEA approach strategy during complex aortic procedures.

Meta-Analysis
BACKGROUND
This study aimed to synthesize data from recently published literature to evaluate the safety and efficacy of endovascular treatment (EVT) for infrarenal aortic occlusion (IAO).
METHODS
The PubMed and Embase were searched to identify all studies reporting EVT for IAO from January 1st, 2000 to December 31st, 2017. Information about patients' characteristics, comorbidities, technical success, mortality, complications, and patency was collected and analyzed.
RESULTS
9 articles consisting of 220 patients were included in this meta-analysis. Patients often had severe symptoms and many comorbidities. The overall technical success and periprocedural mortality was 95.64% (95% confidence interval [CI], 88.60%-99.42%) and 0.35% (95% CI, 0.00% to 2.33%). In successful cases, ankle-brachial index was raised from 0.42 to 0.91. The complication described in one article is of the whole samples and that of the technical success cases was not represented separately. We made the meta-analysis on the other 8 articles. Periprocedural complications included vascular complications (11.35% [95% CI: 3.50%-19.20%]) mainly pseudoaneurysm, thromboses, hematoma, and dissections; limb complications 8.28% (95% CI: 4.86%-13.77%); and renal complications 1.25% (95% CI: 0.00%-3.65%). In an article, vascular complications of whole samples were 12.24%, limb complication 6.12%, and renal complication 10.20%. Overall primary patency was 93.53% (95% CI: 89.37%-97.68%) at 1 year, 78.96% (95% CI: 72.26%-84.96%) at 3 years, and 75.31% (95% CI: 66.42%-84.20%) at 5 years. Overall secondary patency was 98.25% (95% CI: 95.50%-99.73%) at 1 year, 95.92% (95% CI: 89.25%-99.47%) at 3 years, and 94.02% (95% CI: 88.10%-98.00%) at 5 years.
CONCLUSIONS
EVT for IAO is acceptable with relatively high technical success rate, low mortality, and satisfying short-term patency. Although primary patency was lower than after surgery, secondary patency was roughly similar to that of surgical repair. However, this conclusion is based on retrospective observational studies, and the results could be imprecise due to the limited sample sizes, especially in midterm and long-term patency. More studies with longer follow-up and bigger sample size are needed to further elucidate this.

The occipital artery (OA) is a critical artery in vascular lesions. However, a comprehensive review of the importance of the OA is currently lacking. In this study, we used the PubMed database to perform a review of the literature on the OA to increase our understanding of its role in vascular lesions. We also provided our typical cases to illustrate the importance of the OA. The OA has several variations. For example, it may arise from the internal carotid artery or anastomose with the vertebral artery. Therefore, the OA may provide a crucial collateral vascular supply source and should be preserved in these cases. The OA is a good donor artery. Consequently, it is used in extra- to intracranial bypasses for moyamoya disease (MMD) or aneurysms. The OA can be involved in dural arteriovenous fistula (DAVF) and is a feasible artery for the embolisation of DAVF. True aneurysms and pseudoaneurysms can occur in the OA; surgical resection and embolisation are the effective treatment approaches. Direct high-flow AVF can occur in the OA; embolisation treatment is a good option in such cases. The OA can also be involved in MMD and brain arteriovenous malformation (AVM) by forming transdural collaterals. For a patient in the prone position, if occipital and suboccipital craniotomies are performed, the OA can also be used for intraoperative angiography. In brief, the OA is a very important artery in vascular lesions.

Meta-Analysis
BACKGROUND
The evidence supporting management decisions of visceral artery aneurysms (VAAs) is sparse. Practice guidelines are needed to help patients and surgeons choose between endovascular and open surgery approaches.
METHODS
We searched MEDLINE, EMBASE, Cochrane databases, and Scopus for studies of patients with VAAs. Studies were selected and appraised by pairs of independent reviewers. Meta-analysis was performed when appropriate.
RESULTS
We included 80 observational studies that were mostly noncomparative. Data were available for 2845 aneurysms, comprising 1279 renal artery, 775 splenic artery, 359 hepatic artery, 226 pancreaticoduodenal and gastroduodenal arteries, 95 superior mesenteric artery, 87 celiac artery, 15 jejunal, ileal and colic arteries, and 9 gastric and gastroepiploic arteries. Differences in mortality between open and endovascular approaches were not statistically significant. The endovascular approach was used more often by surgeons. The endovascular approach was associated with shorter hospital stay and lower rates of cardiovascular complications but higher rates of reintervention. Postembolization syndrome rates ranged from 9% (renal) to 38% (splenic). Coil migration ranged from 8% (splenic) to 29% (renal). Otherwise, access site complication were low (<5%). Pseudoaneurysms tended to have higher mortality and reintervention rates.
CONCLUSIONS
This systematic review provides event rates for outcomes important to patients with VAAs. Despite the low certainty warranted by the evidence, these rates along, with surgical expertise and anatomic feasibility, can help patients and surgeons in shared-decision making.
