Use of telemedicine for trauma care since the Russian invasion of Ukraine: A qualitative assessment.

INTRODUCTION: Ukraine's health and trauma system has been detrimentally impacted since the start of the Russian invasion in February 2022. Use of telemedicine became critical to providing timely medical care. As such, the aim of this study was to describe telemedicine's use in the health and trauma system of Ukraine following the full-scale invasion. METHODS: We conducted qualitative key informant interviews with military and civilian health care workers using an expanded version of the Global Trauma System Evaluation Tool which had components focusing on telemedicine use. Thematic content analysis was used to derive key telemedicine themes from interviews. RESULTS: We conducted 36 key informant interviews. Most respondents described using telemedicine through informal means of communication such as messaging apps to meet patient care needs. Concerns and challenges with use of telemedicine included weapons targeting, internet connections and safety of communications from Russian hackers. A unified system for telemedicine would greatly improve use in country both during and post conflict. DISCUSSION: Telemedicine use has rapidly increased in Ukraine during the current conflict particularly in the scope of providing trauma care when numerous specialties are needed. Development of a unified, secure telemedicine system with mechanisms for integrating multinational medical support would aid in providing swift medical care to persons injured in the conflict or unable to access a specialty provider in their proximity.

A pseudo-dilemma: Are we over-diagnosing and over-treating traumatic splenic intraparenchymal pseudoaneurysms?

BACKGROUND: Splenic embolization for traumatic vascular abnormalities in stable patients is a common practice. We hypothesize that modern contrast-enhanced computed tomography (CT) over diagnoses posttraumatic splenic vascular lesions, such as intraparenchymal pseudoaneurysms (PSA) that may not require embolization. METHODS: We reviewed the experience at our high-volume center with endovascular management of blunt splenic injuries from January 2016 to December 2021. Multidisciplinary review was used to compared initial CT findings with subsequent angiography, analyzing management and outcomes of identified vascular lesions. RESULTS: Of 853 splenic injuries managed overall during the study period, 255 (29.9%) underwent angiography of the spleen at any point during hospitalization. Vascular lesions were identified on 58% of initial CTs; extravasation (12.2%) and PSA (51.0%). Angiography was performed a mean of 22 hours after admission, with 38% done within 6 hours. Embolization was performed for 90.5% (231) of patients. Among the 130 patients with PSA on initial CT, 36 (27.7%) had no visible lesion on subsequent angiogram. From the 125 individuals who did not have a PSA identified on their initial CT, 67 (54%) had a PSA seen on subsequent angiography. On postembolization CT at 48 hours to 72 hours, persistently perfused splenic PSAs were seen in 41.0% (48/117) of those with and 22.2% (2/9) without embolization. Only one of 24 (4.1%) patients with PSA on angiography observed without embolization required delayed splenectomy, whereas 6.9% (16/231) in the embolized group had splenectomy at a mean of 5.5 ± 4 days after admission. CONCLUSION: There is a high rate of discordance between CT and angiographic identification of splenic PSAs. Even when identified at angiogram and embolized, close to half will remain perfused on follow-up imaging. These findings question the use of routine angioembolization for all splenic PSAs. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Porcine Acellular Dermal Matrix for Hernia Repair in Transplant Patients.

PURPOSE: The purpose of this study was to compare clinical outcomes of incisional hernia repair in solid organ transplant patients using non-cross-linked porcine acellular dermal matrix (PADM), human derived acellular dermal matrix (HADM) and synthetic mesh. METHODS: A retrospective review of patients who underwent hernia repair with PADM after pancreas and/or renal transplant at the University of Maryland Medical Center from 2008 to 2012 was conducted. Repair type, postoperative infection, hernia recurrence, mesh removal, and length of follow-up were recorded. Results were compared with our previously published data evaluating HADM and synthetic mesh used in transplant patients between 2000 and 2005. RESULTS: Twenty-seven patients underwent ventral hernia repair with PADM, 34 patients were repaired with HADM and 26 were repaired with synthetic mesh. The rate of wound infection in those repaired with PADM, HADM, and synthetic mesh were 14.8%, 14.7%, and 65.4%, respectively. Rates of recurrence were 13.3%, 23.5%, and 76.9%, respectively. Rate of mesh removal was found to be 7.4%, 11.8%, and 69.2%, respectively. These complication rates were significantly lower in patients who received HADM or PADM compared with patients repaired with synthetic mesh (P < 0.001). There was no statistically significant difference in the outcomes between the groups repaired with HADM or PADM. CONCLUSIONS: The use of PADM for incisional hernia repair after kidney and/or pancreas transplant significantly reduces the incidence of hernia recurrence, wound infection, and need for mesh removal compared to synthetic mesh. No difference in morbidity between HADM and PADM was observed in the study population; however, longer follow-up in the PADM group is warranted.

Utility of indocyanine green fluorescence lymphography in identifying the source of persistent groin lymphorrhea.

SUMMARY: Surgical manipulation of the groin can result in lymphatic injury in a significant number of patients leading to poor wound healing or infectious complications. Surgical repair of lymphatic injury is greatly aided by the precise and prompt intraoperative localization of the injured lymphatic vessels. We assessed and identified lymphatic leaks in 2 cases of surgical wound lymphorrhea occurring after instrumentation of the groin using laser-assisted indocyanine green lymphography paired with isosulfan blue injection. Both cases healed without complication, and no lymphatic leak recurrence was observed during postoperative follow-up. Laser-assisted indocyanine green lymphography is a useful adjunct in the management of lymphatic leaks after surgery of the groin and may have potential for prophylactic evaluation of high-risk groin wounds.

Novel technique for innervated abdominal wall vascularized composite allotransplantation: a separation of components approach.

OBJECTIVE: Applications for Abdominal Wall Vascularized Composite Allotransplantation may expand if a functional graft with decreased immunosuppressive requirements can be designed. We hypothesize that it is anatomically feasible to prepare a functional, innervated, and vascularized abdominal composite graft using a multilayered component separation technique. Including vascularized bone in the graft design may decrease the immunosuppressive requirements by inducing immunologic chimerism. METHODS: Two cadaver torsos were used. Adipocutaneous flaps were elevated from the midaxillary lines, preserving deep inferior epigastric artery perforators. A 2-layered component separation through the external and internal oblique fasciae was carried out, exposing segmental intercostal thoracolumbar nerves. Superiorly directed muscle release over the subcostal margin provided for a 3-rib segment with attached rectus abdominis muscle. The remainder of the full-thickness allograft was harvested with its vasculature. Flap inset into the recipient cadaver abdomen, with osteosynthesis fixation between donor and recipient ribs, was achieved. RESULTS: The harvested grafts had an average size of 845 ± 205 cm(2) with a total procurement time of 110 minutes. On one cadaver, 4 thoracolumbar nerves were isolated bilaterally, while the other cadaver yielded 3 nerves. The nerves were transected with an average length of 5.7 ± 1.2 cm. The graft vasculature was transected with a length of 4.40 ± 0.10 cm. CONCLUSION: Using the principles of component separation technique, we demonstrated a novel approach to harvest and transfer a neurotized osteomyofasciocutaneous abdominal wall allotransplant as a multipedicled, single functional unit.
