A Patient With Foot Pain Found to Have Leriche Syndrome: A Case Report and Brief Review of the Literature.

Leriche syndrome, a rare and critical complication of peripheral arterial disease (PAD), affects the distal abdominal aorta (infrarenal) and, similar to PAD, is a result of plaque buildup in the arterial lumen. The Leriche syndrome triad includes claudication in the proximal lower extremity, decreased or absent femoral pulses, and, in some cases, impotence. This article presents a patient with an atypical presentation of foot pain who was subsequently found to have Leriche syndrome. The patient was a 59-year-old female, a former smoker, who presented to the emergency department (ED) with atraumatic, acute right foot pain. All right lower extremity pulses were faintly audible on bedside Doppler. Computed tomography with angiography of the abdominal aorta revealed a Leriche-type occlusion of the infrarenal abdominal aorta and left common iliac and a 10 cm right popliteal arterial occlusion. Pharmacological anticoagulation was initiated by the ED. Definitive treatment in this patient included catheter-directed tissue plasminogen activator lysis to the thrombus on the right and placement of kissing stents in the distal aorta without complication. The patient made an excellent recovery and had a complete resolution of her symptoms. PAD is an omnipresent condition and, when untreated, can result in a myriad of high mortality and morbidity conditions such as Leriche syndrome. Collateral vessel formation can make the symptoms of Leriche syndrome vague and inconsistent, often making early recognition difficult. Optimal outcomes hinge on the clinician's ability to efficiently recognize, diagnose, stabilize, and coordinate multidisciplinary involvement of vascular and interventional radiology specialties. Case reports such as this one help to illuminate some of the more infrequent presentations of Leriche syndrome.

Splenic Injury: A Curious Complication of Colonoscopy.

Colonoscopies are generally considered a safe procedure with an overall complication rate of 0.5%. Splenic injuries, including laceration, subcapsular hematoma, and rupture, have been thought to be underreported in the currently available literature. The etiology of splenic injury remains unknown, although excessive splenocolic ligament stretching and traction of adhesions have been hypothesized to play a role in its development. Even though conservative, percutaneous, and surgical strategies have been described in the literature, these strategies have been associated with higher mortality, and there is no consensus on the optimal approach to management. We present the case of a patient who sustained a splenic injury after a colonoscopy and was successfully managed with conservative measures.

Contralateral Inferior Alveolar Nerve Transposition for Simultaneous Dental Implant Placement on a Unilateral Reconstructed Mandible: A Case Report With a 7-Year Follow-Up.

This case report describes an unusual case of implant treatment after contralateral inferior alveolar nerve transposition (IANT) on a unilateral reconstructed mandible due to gunshot trauma with a 7-year follow-up. The patient had an edentulous atrophic mandible and underwent large bone reconstruction on the left side. The irregular passage of the right inferior alveolar nerve was within 1-2 mm of the superior aspect of the mandible, passed through the midline, and was nearly exposed under the oral mucosa at the left anterior part of the mandible, which prevented the placement of conventional implants. Consequently, right IANT followed by iliac onlay bone grafting was undertaken under general anesthesia to create a sufficient bone volume for implant placement. Four implants were installed simultaneously on the augmented bone. After a 2-month waiting period, soft tissue graft placement and vestibuloplasty were performed. The patient was scheduled for a continuous follow-up for the next 7 years. After 3 years, the bar-retained supporting system was replaced with the new CAD/CAM milled bar system on the same 4 implants. The 4 implants presented good initial stability (>35 N/cm), and radiographic evaluation showed osseointegration around all 4 implants. The patient experienced lip numbness in the first 5 days postoperatively but recovered by 97% after 2 months. After a 7-year follow-up, the result remained satisfactory with no sign of bone loss around any of the 4 implants, and the prosthesis functioned well and was stable and esthetically satisfactory. In conclusion, an immediate implant placement procedure after a complex surgery involving unilateral IANT and iliac onlay bone grafting remains challenging, especially when the patient has extensive bone defects or an atrophic mandible. However, a successful long-term outcome can be achieved with appropriate perioperative and postoperative care.

A Rare Case of Hip Pain Secondary to Pigmented Villonodular Synovitis.

A 19-year-old Asian male presented to our emergency department with atraumatic right hip pain radiating to the right groin associated with pain on ambulation. Magnetic resonance imaging of the right hip with and without contrast revealed the diagnosis. Pigmented villonodular synovitis is a rare, monoarticular benign tumor originating from the synovium of the joint. The treatment is synovectomy of the pathological joint to prevent further disease progression.
