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.
REPORT: A 10 year old girl with end stage renal failure dialysing through a left brachiocephalic fistula presented with left upper limb and facial swelling. She had previously exhausted the option of ambulatory peritoneal dialysis for recurrent peritonitis. A central venogram showed occlusion at the left subclavian vein, which was not amenable for angioplasty through either an upper limb or femoral approach. Given the precious fistula with concomitant worsening venous hypertension, an ipsilateral axillary vein to external iliac vein bypass was performed. Subsequently, her venous hypertension was significantly resolved. This report is the first in English literature on this surgical bypass in a child with central venous occlusion.
DISCUSSION: Central venous stenosis or occlusion rates are rising due to extensive central venous catheter use in the paediatric population with end stage renal failure. In this report, an ipsilateral axillary vein to external iliac vein bypass was used successfully as a safe temporary option to maintain AVF. Ensuring a high flow fistula pre-operatively and continued antiplatelet post-operatively will allow longer patency of the graft.
METHODS: This is a retrospective study performed in a vascular surgery unit in a tertiary hospital on patients who underwent AKAs over 1 year, from July 2021 until June 2022. Patient demographic data, WIfI scoring, outcome of AKAs, and patency of profunda femoris and internal iliac artery (IIA) were collected. To minimize confounding, a single vascular surgeon performed all computed tomography imaging reviews and arterial measurements. Approval for this study was obtained from the National Research Registry, NMRR ID-23-01865-KQ4 (investigator initiated research).
RESULTS: Ninety patients underwent AKA over 1 year, from July 2021 until June 2022. Occluded IIA in the presence of patent profunda femoris did not affect the wound healing of the AKA stump. There was significant association between WIfI scoring and mortality. Patients with a WIfI scoring of 3 to 4 were observed to have a higher mortality rate compared with patients with normal healing: 47 (72.0%) vs. 4 (80.0%); P = 0.021.
CONCLUSIONS: In this study, the IIA patency shows no statistically significant effect on AKA stump healing; however, the small number of patients is a drawback of the study. This study also demonstrates that the WIfI score can be a prognostic factor for mortality in patients undergoing AKA.
