Profunda femoris pseudoaneurysm rupture post dynamic hip screw fixation after physiotherapy.

This case discusses an elderly female who presented acutely with compromised profunda femoris pseudoaneurysm and massive haematoma five weeks after dynamic hip screw insertion for a left neck of femur fracture. The only precipitating factor leading to this presentation was ongoing physiotherapy. She was referred from a rehabilitation hospital to the nearest vascular surgical unit for acute and definitive surgical intervention. Post-operatively, she fared incredibly well, regaining her baseline level of functioning. History taking is complex in a patient with dementia. Clinical examination should follow with a focused approach to the site of recent operation and also where complications are likely to manifest when an alteration from baseline cognitive function is noted. This is of course in addition to the complete work up required from a holistic perspective with any acute deterioration. Imaging should be arranged and prompt referral made if a treatable acute cause is identified. It is imperative to involve family and/or next of kin if possible, but this should not impede prompt decision-making in the patient's best interests by the clinical team if delays are likely to occur.

Prospective Study on the Efficacy of Orally Administered Tranexamic Acid and Goreisan for the Prevention of Recurrence After Chronic Subdural Hematoma Burr Hole Surgery.

OBJECTIVE: This prospective study investigated whether tranexamic acid and Goreisan effectively prevent recurrence after burr hole surgery for chronic subdural hematoma. METHODS: A total of 297 patients with chronic subdural hematoma underwent initial burr hole surgery at our hospital from April 2014 to March 2018. Of these, 206 patients (250 hematomas) consented to participate in this study. Patients were randomly divided into the nonadministration, tranexamic acid, and Goreisan groups based on age. The oral administration intervention was implemented from the day after surgery, after which there was a 3-month follow-up. Recurrence rates were measured, and head computed tomography scan was used to measure the volume of residual hematoma 1 day, 1 week, and 1, 2, and 3 months after surgery. RESULTS: A total of 193 patients (232 hematomas) were followed-up for 3 months (82 hematomas in the nonadministration group, 72 hematomas in the tranexamic acid group, and 78 hematomas in the Goreisan group). There were no significant between-group differences in demographic characteristics, current drug treatment, comorbidities, hematoma, operation side (bilateral or unilateral), preoperative hematoma volume, and recurrence rates. At 1, 2, and 3 months, the residual hematoma volume was significantly smaller in the tranexamic acid group than in the other 2 groups. CONCLUSIONS: Oral administration of tranexamic acid or Goreisan does not minimize recurrence after chronic subdural hematoma burr hole surgery; however, tranexamic acid can reduce the hematoma volume.

What the radiologist should know about postoperative MDCT evaluation of a patient treated with cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy.

Cytoreductive surgery (CRS), often associated with hyperthermic intraperitoneal chemotherapy (HIPEC), is now a well-recognised treatment for most peritoneal malignancies in selected patients. As imaging is frequently performed postoperatively, radiologists are increasingly confronted with postoperative multidetector-row computed tomography (MDCT) examinations in these cases. In this article, after briefly describing the procedures that are currently being performed for the treatment of peritoneal metastases, the normal postoperative MDCT changes that may be encountered after these procedures are described. We then highlight complications that may arise after CRS, depending on the surgery performed, and those related to HIPEC, and illustrate their MDCT features.

Significant Hemorrhage Rate Reduction after Gamma Knife Radiosurgery in Symptomatic Cavernous Malformations: Long-Term Outcome in 95 Case Series and Literature Review.

BACKGROUND: The natural history of cavernous malformations (CMs) has remained unclear. This lack of knowledge has made treatment decisions difficult. Indeed, the use of stereotactic radiosurgery is nowadays controversial. The purpose of this paper is to throw light on the effectiveness of Gamma Knife radiosurgery (GKRS) therapy. METHODS: The authors reviewed data collected from a prospectively maintained database. A total of 95 patients (57 female and 38 male) underwent GKRS for high-surgical-risk CMs. A total of 76 cavernomas were deeply located (64 lesions in the brainstem and 12 lesions in the thalamus). All of them were located in eloquent regions. The median malformation volume was 1,570 mm3. The median tumor margin dose was 11.87 Gy, and the mean tumor maximum dose was 19.56 Gy. RESULTS: Ninety-five cavernous CMs were managed from 1994 to 2014. All patients had experienced at least 1 symptomatic bleeding incident before treatment (only 1 hemorrhage event in 81%). The median length of follow-up review was 78 months. The pretreatment annual hemorrhage rate was 3.06% compared with 1.4% during the first 3-year latency interval, and 0.16% thereafter (p = 0.004). Four patients developed new location-dependent neurological deficits, and 3 patients had edema-related headache after radiosurgery. All of them presented full recovery. CONCLUSIONS: The best dosage range for preventing bleeding was identified as between 11 and 12 Gy in our series. Although the efficacy of radiosurgery in CMs remains impossible to quantify, a very significant reduction in the bleeding rate occurs after a 3-year latency interval. No permanent neurological morbidity is reported in our series. These results defend the safety of GKRS in surgical high-risk CM from the first bleeding event.

Evolution in the Treatment of Delayed Postpancreatectomy Hemorrhage: Surgery to Interventional Radiology.

OBJECTIVES: We summarized a single center's evolution in the management of postpancreatectomy hemorrhage (PPH) from surgical toward endovascular management. METHODS: Between 2003 and 2013, 337 patients underwent Whipple procedures. Using the International Study Group of Pancreatic Surgery (ISGPS) consensus definition, patients with PPH were identified and retrospectively analyzed for the presentation of hemorrhage, type of intervention, and 90-day mortality outcome measures. RESULTS: Management evolved from operative intervention alone, to combined operative and on-table angiographic intervention, to endovascular intervention alone. The prevalence of PPH was 3.0%. Delayed PPH occurred with a mean of 13.8 days. On angiography, visceral arteries affected were the gastroduodenal artery, hepatic artery, jejunal branches of the superior mesenteric artery, pancreaticoduodenal artery, and inferior phrenic artery. Ninety-day mortality for PPH was 20%. From early to recent experience, the mortality rate was 100% for operative intervention alone, 25% for combined operative and on-table angiographic intervention, and 0% for endovascular intervention alone. CONCLUSIONS: Our 10-year experience supports current algorithms in the management of PPH. Key considerations include the recognition of the sentinel bleed, the presence of a pancreatic fistula, and the initial operative role of a long gastroduodenal artery stump with radiopaque marker for safe and effective embolization should PPH occur.

N-butyl cyanoacrylate embolization for pseudoaneurysms complicating pancreatitis or pancreatectomy.

PURPOSE: To evaluate the clinical effectiveness and safety of transcatheter arterial embolization with n-butyl cyanoacrylate (NBCA) for pseudoaneurysms complicating pancreatitis or pancreatectomy. MATERIALS AND METHODS: Twelve procedures were performed in nine patients (seven men and two women; mean age, 60.6 years) for pseudoaneurysms that occurred secondary to pancreatitis or as a consequence of pancreatic juice leakage at the site of pancreatectomy. For embolization, NBCA was mixed with iodized oil at a ratio of 1:1-1:4; in one patient with failed selective catheterization of the target vessel, the mixture ratio was 1:9. Technical and clinical success rates, recurrent bleeding, procedural complications, serum amylase level, and clinical outcome were determined for each procedure. RESULTS: Embolization was technically successful in all procedures, with no recurrent bleeding documented from the initially treated territory. In three procedures, we encountered additional bleeding vessels at 11, 33, and 49 days after the procedures, which were successfully managed by a second embolization in each case. There were no major complications related to the procedures. As minor complications, in two procedures, the embolized material overflowed beyond the target vessels; however, no clinically significant ischemic events were observed in the embolized territories. Serum amylase did not increase compared with initial levels after any of the procedures. Seven patients were discharged after clinical improvement. Two patients died 2 and 3 weeks after the embolization as a result of multiple organ failure not associated with the procedure. CONCLUSIONS: In this limited series, NBCA embolization was found to be feasible and effective for pseudoaneurysms as a complication of pancreatitis or pancreatectomy.
